This document summarizes a research article that analyzes food demand for carbohydrate sources in Indonesia using the Linear Approximation-Almost Ideal Demand System (LA-AIDS) model. The study uses household expenditure and consumption data from Indonesia's 2016 National Socio-Economic Survey. The results show differences in demand between rural and urban households for commodities like rice, corn, cassava, sweet potatoes, and wheat flour, which are influenced by price, income, and household size. Rice has the most inelastic price demand compared to other commodities. The study aims to provide information on managing staple food prices and diversifying carbohydrate sources.
The effects of food price increases on urban household food commodities expen...nanaeghan
The document analyzes the effects of food price increases on urban household food expenditures in Ghana using data from the Ghana Living Standard Survey. It estimates price and income elasticities of demand for 11 food groups using the Linear Almost Ideal Demand System model, controlling for expenditure endogeneity and sample selection bias. The results show that household demographic characteristics like household size, education level, sex, and age of the household head significantly influence urban households' food expenditures. Cereals, roots and tubers, fish, and vegetables collectively account for about 78% of future urban food expenditures based on marginal expenditure shares. The study finds that rising urbanization presents market opportunities for Ghana's economy if appropriate agricultural policies focus on increasing food production.
Study of Lifestyle Trends on Changing Food Habits of Indian Consumersiosrjce
Global markets have increased the plethora of options available to Indian consumers. With the clear
shift in consumer tastes and preferences, food companies have also capitalized on the same. While Indian
consumers are still not as heavily impacted by the obesity epidemic like some other developed nations – there is
a clear shift; one which does not augur well for the health of the average citizen. The objective of this paper was
to identify these key lifestyle trends that have emerged over the dozen years or so – and understand the way they
are changing food habits. For this purpose, we talked to 600 respondents across 6 cities in India. The research
was conducted using a questionnaire administered online and through CATI. The results overwhelmingly show
that there is a shift from opting to eat at home to opting to eat out. Also interestingly awareness about harmful
effects of processed foods was high but the reason for consumption was attributed primarily to ease of purchase.
The implications of the research are an attempt to ensure that key steps are taken by public officials: such as a
tax on unhealthy foods, subsidies for healthy food, and promotion of healthy norms. Also FSSAI guidelines need
to strengthen to ensure that customer awareness increase and food companies opt for a more transparent
communication platform.
Study on Income Effect of Nutrient Intake Structure of Migrant Workers: The C...Dr. Amarjeet Singh
This paper empirically analyzes the income effect of the nutrient intake structure of migrant workers based on the 2014 survey data on the employment and food demand of urban migrant workers in China. The results showed that after controlling for factors such as labor intensity, height and weight, the monthly average income significantly increased the calorie intake of migrant workers, and the income elasticity was 0.052. From the perspective of nutrient intake structure, the average monthly income had no significant effect on the carbohydrate intake of migrant workers, but significantly increased the fat and protein intake of migrant workers, and the income elasticity was 0.222 and 0.075, respectively. Nutrition has not linear relationship between demand and income. The effect of average income on caloric intake of migrant workers in low income group, middle income group and high income group decreases with the increase of income group, until it has no significant effect on high income group, and heat demand income elasticity of low-income as well as middle-income group of migrant workers was 0.182 and 0.092, respectively.
This document summarizes a study that estimates output supply and input demand elasticities for rice production in Sri Lanka using a restricted normalized translog profit function approach. The study analyzes four major rice producing districts from 1990-2012. The results show that changes in input and output prices significantly affect farmer profits, rice supply, and input use. Rice supply elasticity with respect to price is 0.5, while fertilizer demand elasticity with respect to price is -0.05 on average. Fertilizer subsidy increases both fertilizer demand and rice supply. Low substitution elasticity between labor and fertilizer indicates complementary relationships that synergistically increase production when applied together. Overall, higher output prices are essential for greater rice production according to
Urbanization and pattern of urban food consumption in ashanti region, ghana ...Alexander Decker
Urbanization is rapidly increasing food insecurity in Ghana's Ashanti region. A study of 116 urban households found:
1) Yam, cassava, and rice have become more important in urban diets, comprising 64.3% of consumption on average.
2) Urban households spend 74.6% of their budget on food, indicating rising urban food prices are a challenge.
3) The estimated food security index was 0.66, meaning urban households do not meet the minimum daily calorie requirement on average and are food insecure.
4) Specifically, 78.5% of respondents were food insecure, and 34.2% experienced severe food insecurity.
DETERMINANT OF RICE CONSUMPTION: EVIDENCE FROM PANEL DATA IN INDONESIAIAEME Publication
Rice is the main staple food for the population of Indonesia. Although people in several provinces such as Papua and Maluku initially consumed staple foods other than rice such as sago and tubers, they are currently switching to consuming rice. Rice demand for consumption in Indonesia is increasing with the increasing population. This study aims to determine the dynamics of rice consumption and its determinants in Indonesia. The data used are data originating from the Central Bureau of Statistics and the Ministry of Agriculture, which includes data from 33 provinces in the period 2010-2018. The data was analyzed using panel data regression analysis with the selected model fixed effect model on the equality of functions of rice consumption in Indonesia. The results of the analysis show that rice consumption in Indonesia influenced by the number of households, rice prices, cooking oil prices, chicken prices, participation in rice consumption, age and social assistance. Price elasticity and income elasticity is inelastic, but income elasticity not statistically significant. There are indications that food diversification is happening, can be seen from consumption decline due to social assistance which provides alternative choices of consumption

Analysis of Rural Households Food Security Status in Dibatie District, Wester...Premier Publishers
This study examines the rural household’s food security status and its determinants in the Dibatie district of Bebishangul Gumuz region. The simple random sampling technique was used to select respondents with proportionate sample size based on the number of households that exists in sampled kebele administrations. The data were collected using structured questionnaires and key informants interviews. Both descriptive statistics and econometric model (binary logit model) were used to analyze this data at household levels. Food Security Index is used to measure the food security status of sample households based on average kcal/day/adult equivalent. The results of this study revealed that households of 59.4% were found food secure and 46.6% food insecure. The mean calorie intake of all sampled households was 2431.68kcal/day/equivalent. Furthermore, estimated a binary logit model results show that the variables such as education level of household head, utilization of formal credit, cultivated land size, access to training, farm experience, household size and distance to nearest market were found significant influence on households’ food security status in the study area. However, the remaining variables were not found significant effect on households’ food security status. Finally, the study suggests that any interventions designed to promote farmers to increase food security status at household level in the study area are welcome.

The study aimed to identify the key factors influencing food insecurity in urban areas to help policymakers address the problem.
Review on Consumer Preference of Milk and Milk Product in EthiopiaAI Publications
The aim of this review was to assesses consumer preferences and its determinates towards milk and milk product in Ethiopia. To do this review secondary data such as books, journals, and domestic and foreign published articles were used. According to different past studies result fresh milk, traditional butter, butter milk, cottage cheese, whey and ghee were the common products which consumed frequently in almost all part of the country. Fresh milk was the most preferable product in the country as compared to others due to high fat content, availability, taste and lower price. The review indicates that better educated household head, higher income households, younger and female household head and people who agree with “unpacked and unprocessed milk is not healthy” consume more packed and processed /pasteurized / milk than do others. Generally, consumer preference towards milk and milk product were significantly dependent on demographic, socioeconomic and psychological characteristics of household as well as market mixed variables includes product characteristics, pricing strategies, packaging, Promotion and place factors. thus, it is recommended that, milk producing and processing companies need to design better pricing, promotion and advertising strategies for different milk product consumption to attract consumers.

Exploring dietary diversity, nutritional status of adolescents amongfarmhouse...Olutosin Ademola Otekunrin
Purpose –This study aims to explore dietary diversity (DD) and nutritional status of adolescents among rural farm households in Southwestern Nigeria. It analyses whether higher commercialization levels of farm households translate to better nutrition. Design/methodology/approach –This study was conducted in Ogun and Oyo States of Southwestern Nigeria, using primary data from352 farm households with a total of 160 adolescent members. The individual version of dietary diversity score (DDS) of nine food groups was used to calculate adolescent DDS over a 24-h recall period. World Health Organization AnthroPlus software was used in analyzing adolescents’ anthropometric data (height-for-age z-score and body mass index-for-age z-score) while household crop commercialization index (CCI) was estimated for each farm household. Separate logit models were used to examine thedriversof adolescents’ DDandmalnutrition. Findings –Thestudyfindings indicated that 100% of the adolescents consumed starchy staples while 0%, 3.1% and 12.5% consumed organ meat, milk/milk products and eggs, respectively. Results revealed that 74.1%and21.2%ofboyswerestuntedandthinwhiletheprevalenceinadolescent girls was 50.7%and9.3%, respectively. Prevalence of stunting was found to be very high (60%–83%) in all the four CCI levels’ households indicating that belonging to highly commercialized households (CCI 3–4) may not necessarily translate to better nutrition of adolescent members. Food expenditure (p < 0.01) and access to piped water (p <0.01) negatively influenced adolescents’ stunting mainly because of lower expenditure on food items and lower percent of household having access to piped water, respectively, while education (p < 0.01) had positive effects on adolescents’ DD. Originality/value –Previous studies have contributed to the body of knowledge concerning the link between agricultural commercialization and nutrition using under-five children of the households. However, to the best of the authors’ knowledge, this is the first study that investigated the influence of CCI on DDSandnutritional status of adolescent members of farm households in Nigeria. This study fills this existing knowledge gap in investigating adolescents’ DD and malnutrition among smallholder farm households.

Determinants of Farmers’ Willingness to Pay for Improved Irrigation Water Use...AI Publications
The main objective of this study was to identify the key determinants of farmers’ willingness to pay for improved irrigation water use using the contingent valuation method. Cross sectional data were collected from 251 households using a two-stage sampling technique (purposive and random sampling techniques) from four kebeles of Woliso District through a semi-structured questionnaire. The result from the Tobit model revealed that education level, family size, irrigable land size, number of oxen owned, total annual income, experience in irrigated farming, dissatisfaction, credit utilization and cash crops have significant and positive effect on households’ WTP for the improvement of the existing irrigation use whereas initial bid was found to have a negative and significant effect. Since these variables are identified as major determinants of willingness to pay for improved irrigation water use, policy makers and government should take into account in the designing of improved irrigation water supply system.

Agri-Food Supply Chain Management Literature ReviewJim Webb
This document provides a literature review of research on agri-food supply chain management. It analyzed over 100 research articles on the topic from 2006-2016. The review classified the literature into four categories: general literature reviews of agri-food supply chains, policies affecting supply chain segments, analyses of individual supply chain segments, and performance of supply chain segments. Descriptive analytics using Nvivo software showed that most research focused on terms like supply, farmers, chain, and food, but few addressed business management aspects. The review identified gaps in research on specific commodity supply chains like potatoes in India and opportunities to further analyze relationships between supply chain actors and improve efficiency.
Food is life and the global food sustainability is essential to human being survival. The global food system is highly
complex and is driven by various factors including environment, cultural, social and economic drive. It is vital to understand
these drivers and their interaction in order to help to improve the public food sustainability policies. Global polices and projects
desperately required in order improving the global food sustainability. Food sustainability is one of the unsolved global issues
and great commitment is required starting from global policy makers, national governments, and every individual home. This
research paper includes analysis and study of various elements such as global change science, policy, food crisis, factor affecting
and challenging food security, data on status and future projection and potential ways of solving problems. The goal of food
sustainability is to enable all people throughout the world to satisfy their basic needs and have a reasonable quality of life without
compromising the quality of life of future generations. Agriculture sustainability is the best solution which can feed the world
without compromising the environment or threatening human health. Scientific evidence that global environment has changed
is overwhelming and indisputable. These phenomena have a direct impact on agriculture which in turn affects food
sustainability. The food price is always toward upward trend which is validated by the periodic average global food price
monitoring report released by the Food and agricultural organizations. The factors affecting and challenging the food security
are many including increased food consumption due to population increase, uneven distribution, changes in living styles, limited
resources, environmental problems, economic problems and others. The potential ways to solve food sustainability need to be
established and implemented effectively across the world.
This document summarizes the transformation of China's pig industry from smallholder farms to larger, more industrialized operations based on national statistics and the authors' field surveys. National statistics show the share of pig production from small farms (less than 50 pigs) declining from 73% in 2003 to 29% in 2010, while production on the largest farms (over 500 pigs) increased from 0% to 47% of national production over this period. The authors' detailed field surveys found continuing consolidation of pig production in the towns and villages they studied between 2004 and 2012, with more production shifting to medium and large-scale commercial farms. This transformation brings new opportunities but also challenges around environmental sustainability and impacts on small farmers.

This document summarizes a study that investigated demand response for carbohydrate foods like gari and rice in Imo State, Nigeria. Data was collected on prices and quantities demanded of gari and rice (as substitutes) from three markets between January to December 2012. The data was analyzed using descriptive statistics, charts, and econometric models. Error correction models were developed for each market. Results showed that gari demand was normal except during festivals. Lagged own price of gari was negative and inelastic, indicating gari is a normal good. Reducing gari price in Ihiagwa market could improve food security. Rice was a better substitute to gari in Relief market. The study recommends steady, reduced prices for
Analytical Approach to Recycle the Vegetable and Fruit Waste into Feedijtsrd
The worlds population is projected to grow from about 7.7 billion in 2019 to 9.6 billion people by 2050. More than half of this growth is expected in Sub Saharan Africa SSA China and India. In addition to population growth, per capita meat and milk consumption is also growing, especially in China and India. As the cities are urbanizing and population is migrating in search of better living standards there is double impulse for food in these magnets of growth. In food the demand of fruits and vegetables as well as dairy and meat products is increased gradually in last decade which correspondingly lead to the demand of feed for animals. In this research paper we are presenting a mechanism to convert the vegetable and fruit waste into animal feed by designed feed making machine and its impact on environment in terms of fewer quanta discarded to dumping yard and less production of methane emission due to fruit and vegetable waste. And the scope of recycling the waste will be assessed on pigsty in Pune.

The long run impact of climate change on the productivity of major crops in the districts of Punjab is analyzed for the time period of 1970 to 2010. This study used deviations from average maximum annual temperature and deviations from average rainfall are used as indicators for climate change. While other variables include sale price, fertilizer use and number of tube wells. In order to incorporate long timer periods, this study used Panel ARDL model. The results show that cotton productivity is more positively sensitive to price changes; an increase in temperature, tube wells and fertilizers while wheat productivity is more positively sensitive to the rainfall in the long run. Consequently, in the short run, wheat productivity equilibrium is faster converging. Hence deviations from average rainfall are harmful to cotton crop in the long run and cotton & wheat in the short run, while deviations in maximum temperature is only harmful for cotton crop in the short run.
The Statutory Interpretation of Renewable Energy Based on Syllogism of Britis...AI Publications
The current production for energy consumption generates harmful impacts of carbon dioxide to the environment causing instability to sustainable development goals. The constitutional reforms of British Government serve to be an important means of resolving any encountered incompatibilities to political environment. This study aims to evaluate green economy using developed equation for renewable energy towards political polarization of corporate governance. The Kano Model Assessment is used to measure the equivalency of 1970 Patents Act to UK Intellectual Property tabulating the criteria for the fulfillment of sustainable development goals in respect to the environment, artificial intelligence, and dynamic dichotomy of administrative agencies and presidential restriction, as statutory interpretation development to renewable energy. The constitutional forms of British government satisfy the sustainable development goals needed to fight climate change, advocate healthy ecosystem, promote leadership of magnates, and delegate responsibilities towards green economy. The presidential partisanship must be observed to delineate parties of concerns and execute the government prescriptions in equivalence to the dichotomous relationship of technology and the environment in fulfilling the rights and privileges of all citizens. Hence, the political elites can execute corporate governance towards sustainable development of renewable energy promoting environmental parks and zero emission target of carbon dioxide discharges. The economic theory developed in statutory interpretation for renewable energy serves as a tool to reduce detrimental impacts of carbon dioxide to the environment, mitigate climate change, and produce artefacts of bioenergy and artificial intelligence promoting sustainable development. It is suggested to explore other vulnerabilities of artificial intelligence to prosper economic success.

Food Security Index is used to measure the food security status of sample households based on average kcal/day/adult equivalent. The results of this study revealed that households of 59.4% were found food secure and 46.6% food insecure. The mean calorie intake of all sampled households was 2431.68kcal/day/equivalent. Furthermore, estimated a binary logit model results show that the variables such as education level of household head, utilization of formal credit, cultivated land size, access to training, farm experience, household size and distance to nearest market were found significant influence on households’ food security status in the study area. However, the remaining variables were not found significant effect on households’ food security status. Finally, the study suggests that any interventions designed to promote farmers to increase food security status at household level in the study area are welcome.

The study aimed to identify the key factors influencing food insecurity in urban areas to help policymakers address the problem.
Review on Consumer Preference of Milk and Milk Product in EthiopiaAI Publications
The aim of this review was to assesses consumer preferences and its determinates towards milk and milk product in Ethiopia. To do this review secondary data such as books, journals, and domestic and foreign published articles were used. According to different past studies result fresh milk, traditional butter, butter milk, cottage cheese, whey and ghee were the common products which consumed frequently in almost all part of the country. Fresh milk was the most preferable product in the country as compared to others due to high fat content, availability, taste and lower price. The review indicates that better educated household head, higher income households, younger and female household head and people who agree with “unpacked and unprocessed milk is not healthy” consume more packed and processed /pasteurized / milk than do others. Generally, consumer preference towards milk and milk product were significantly dependent on demographic, socioeconomic and psychological characteristics of household as well as market mixed variables includes product characteristics, pricing strategies, packaging, Promotion and place factors. thus, it is recommended that, milk producing and processing companies need to design better pricing, promotion and advertising strategies for different milk product consumption to attract consumers.

Exploring dietary diversity, nutritional status of adolescents amongfarmhouse...Olutosin Ademola Otekunrin
Purpose –This study aims to explore dietary diversity (DD) and nutritional status of adolescents among rural farm households in Southwestern Nigeria. It analyses whether higher commercialization levels of farm households translate to better nutrition. Design/methodology/approach –This study was conducted in Ogun and Oyo States of Southwestern Nigeria, using primary data from352 farm households with a total of 160 adolescent members. The individual version of dietary diversity score (DDS) of nine food groups was used to calculate adolescent DDS over a 24-h recall period. World Health Organization AnthroPlus software was used in analyzing adolescents’ anthropometric data (height-for-age z-score and body mass index-for-age z-score) while household crop commercialization index (CCI) was estimated for each farm household. Separate logit models were used to examine thedriversof adolescents’ DDandmalnutrition. Findings –Thestudyfindings indicated that 100% of the adolescents consumed starchy staples while 0%, 3.1% and 12.5% consumed organ meat, milk/milk products and eggs, respectively. Results revealed that 74.1%and21.2%ofboyswerestuntedandthinwhiletheprevalenceinadolescent girls was 50.7%and9.3%, respectively. Prevalence of stunting was found to be very high (60%–83%) in all the four CCI levels’ households indicating that belonging to highly commercialized households (CCI 3–4) may not necessarily translate to better nutrition of adolescent members. Food expenditure (p < 0.01) and access to piped water (p <0.01) negatively influenced adolescents’ stunting mainly because of lower expenditure on food items and lower percent of household having access to piped water, respectively, while education (p < 0.01) had positive effects on adolescents’ DD. Originality/value –Previous studies have contributed to the body of knowledge concerning the link between agricultural commercialization and nutrition using under-five children of the households. However, to the best of the authors’ knowledge, this is the first study that investigated the influence of CCI on DDSandnutritional status of adolescent members of farm households in Nigeria. This study fills this existing knowledge gap in investigating adolescents’ DD and malnutrition among smallholder farm households.

Determinants of Farmers’ Willingness to Pay for Improved Irrigation Water Use...AI Publications
The main objective of this study was to identify the key determinants of farmers’ willingness to pay for improved irrigation water use using the contingent valuation method. Cross sectional data were collected from 251 households using a two-stage sampling technique (purposive and random sampling techniques) from four kebeles of Woliso District through a semi-structured questionnaire. The result from the Tobit model revealed that education level, family size, irrigable land size, number of oxen owned, total annual income, experience in irrigated farming, dissatisfaction, credit utilization and cash crops have significant and positive effect on households’ WTP for the improvement of the existing irrigation use whereas initial bid was found to have a negative and significant effect. Since these variables are identified as major determinants of willingness to pay for improved irrigation water use, policy makers and government should take into account in the designing of improved irrigation water supply system.

Agri-Food Supply Chain Management Literature ReviewJim Webb
This document provides a literature review of research on agri-food supply chain management. It analyzed over 100 research articles on the topic from 2006-2016. The review classified the literature into four categories: general literature reviews of agri-food supply chains, policies affecting supply chain segments, analyses of individual supply chain segments, and performance of supply chain segments. Descriptive analytics using Nvivo software showed that most research focused on terms like supply, farmers, chain, and food, but few addressed business management aspects. The review identified gaps in research on specific commodity supply chains like potatoes in India and opportunities to further analyze relationships between supply chain actors and improve efficiency.
Food is life and the global food sustainability is essential to human being survival. The global food system is highly
complex and is driven by various factors including environment, cultural, social and economic drive. It is vital to understand
these drivers and their interaction in order to help to improve the public food sustainability policies. Global polices and projects
desperately required in order improving the global food sustainability. Food sustainability is one of the unsolved global issues
and great commitment is required starting from global policy makers, national governments, and every individual home. This
research paper includes analysis and study of various elements such as global change science, policy, food crisis, factor affecting
and challenging food security, data on status and future projection and potential ways of solving problems. The goal of food
sustainability is to enable all people throughout the world to satisfy their basic needs and have a reasonable quality of life without
compromising the quality of life of future generations. Agriculture sustainability is the best solution which can feed the world
without compromising the environment or threatening human health. Scientific evidence that global environment has changed
is overwhelming and indisputable. These phenomena have a direct impact on agriculture which in turn affects food
sustainability. The food price is always toward upward trend which is validated by the periodic average global food price
monitoring report released by the Food and agricultural organizations. The factors affecting and challenging the food security
are many including increased food consumption due to population increase, uneven distribution, changes in living styles, limited
resources, environmental problems, economic problems and others. The potential ways to solve food sustainability need to be
established and implemented effectively across the world.
This document summarizes the transformation of China's pig industry from smallholder farms to larger, more industrialized operations based on national statistics and the authors' field surveys. National statistics show the share of pig production from small farms (less than 50 pigs) declining from 73% in 2003 to 29% in 2010, while production on the largest farms (over 500 pigs) increased from 0% to 47% of national production over this period. The authors' detailed field surveys found continuing consolidation of pig production in the towns and villages they studied between 2004 and 2012, with more production shifting to medium and large-scale commercial farms. This transformation brings new opportunities but also challenges around environmental sustainability and impacts on small farmers.

Analytical Approach to Recycle the Vegetable and Fruit Waste into Feedijtsrd
The worlds population is projected to grow from about 7.7 billion in 2019 to 9.6 billion people by 2050. More than half of this growth is expected in Sub Saharan Africa SSA China and India. In addition to population growth, per capita meat and milk consumption is also growing, especially in China and India. As the cities are urbanizing and population is migrating in search of better living standards there is double impulse for food in these magnets of growth. In food the demand of fruits and vegetables as well as dairy and meat products is increased gradually in last decade which correspondingly lead to the demand of feed for animals. In this research paper we are presenting a mechanism to convert the vegetable and fruit waste into animal feed by designed feed making machine and its impact on environment in terms of fewer quanta discarded to dumping yard and less production of methane emission due to fruit and vegetable waste. And the scope of recycling the waste will be assessed on pigsty in Pune.

The long run impact of climate change on the productivity of major crops in the districts of Punjab is analyzed for the time period of 1970 to 2010. This study used deviations from average maximum annual temperature and deviations from average rainfall are used as indicators for climate change. While other variables include sale price, fertilizer use and number of tube wells. In order to incorporate long timer periods, this study used Panel ARDL model. The results show that cotton productivity is more positively sensitive to price changes; an increase in temperature, tube wells and fertilizers while wheat productivity is more positively sensitive to the rainfall in the long run. Consequently, in the short run, wheat productivity equilibrium is faster converging. Hence deviations from average rainfall are harmful to cotton crop in the long run and cotton & wheat in the short run, while deviations in maximum temperature is only harmful for cotton crop in the short run.

The Statutory Interpretation of Renewable Energy Based on Syllogism of Britis...AI Publications
The current production for energy consumption generates harmful impacts of carbon dioxide to the environment causing instability to sustainable development goals. The constitutional reforms of British Government serve to be an important means of resolving any encountered incompatibilities to political environment. This study aims to evaluate green economy using developed equation for renewable energy towards political polarization of corporate governance. The Kano Model Assessment is used to measure the equivalency of 1970 Patents Act to UK Intellectual Property tabulating the criteria for the fulfillment of sustainable development goals in respect to the environment, artificial intelligence, and dynamic dichotomy of administrative agencies and presidential restriction, as statutory interpretation development to renewable energy. The constitutional forms of British government satisfy the sustainable development goals needed to fight climate change, advocate healthy ecosystem, promote leadership of magnates, and delegate responsibilities towards green economy. The presidential partisanship must be observed to delineate parties of concerns and execute the government prescriptions in equivalence to the dichotomous relationship of technology and the environment in fulfilling the rights and privileges of all citizens. Hence, the political elites can execute corporate governance towards sustainable development of renewable energy promoting environmental parks and zero emission target of carbon dioxide discharges. The economic theory developed in statutory interpretation for renewable energy serves as a tool to reduce detrimental impacts of carbon dioxide to the environment, mitigate climate change, and produce artefacts of bioenergy and artificial intelligence promoting sustainable development. It is suggested to explore other vulnerabilities of artificial intelligence to prosper economic success.

Analysis of Value Chain of Cow Milk: The Case of Itang Special Woreda, Gambel...AI Publications
Ethiopia has a long and rich history of dairy farming, which was mostly carried out by small and marginal farmers who raised cattle, camels, goats, and sheep, among other species, for milk. Finding the Itang Special Woreda cow milk value chain is the study's main goal. In order to gather primary data, 204 smallholder dairy farmer households were randomly selected, and the market concentration ratio was calculated using 20 traders. Descriptive statistics, econometric models, and rank analysis were used to achieve the above specified goals. Out of all the participants in the milk value chain, producers, cafés, hotels, and dairy cooperatives had the largest gross marketing margins, accounting for 100% of the consumer price in channels I and II, 55% in channels III and V, and 25.5% in channels V. The number of children under five, the number of milking cows owned, the amount of money from non-dairy sources, the frequency of extension service contacts, the amount of milk produced each day, and the availability of market information were found to have an impact on smallholders' involvement in the milk market. Numerous obstacles also limited the amount of milk produced and marketed. The poll claims that general health issues, sickness, predators, and a lack of veterinary care are plaguing farmers. In order to address the issue of milk perishability, the researchers recommended the host community and organization to construct an agro milk processor, renovate the dairy cooperative in the study region, and restructure the current conventional marketing to lower the transaction and cost of milk marketing.
Minds and Machines: Impact of Emotional Intelligence on Investment Decisions ...AI Publications
In the evolving landscape of financial decision-making, this study delves into the intricate relationships among Emotional Intelligence (EI), Artificial Intelligence (AI), and Investment Decisions (ID). By scrutinizing the direct influence of human emotional intelligence on investment choices and elucidating the mediating role of AI in this process, our research seeks to unravel the complex interplay between minds and machines. Through empirical analysis, we reveal that EI not only directly impacts ID but also exerts its influence indirectly through AI-mediated pathways. The findings underscore the pivotal role of emotional awareness in investor decision-making, augmented by the technological capabilities of AI. It suggests that most investors are influenced by the identified emotional intelligence when making investment decisions. Furthermore, AI substantially impacts investors' decision-making process when it comes to investing; nevertheless, AI partially mediates the relationship between emotional intelligence and investment decisions. This nuanced understanding provides valuable insights for financial practitioners, policymakers, and researchers, emphasizing the need for holistic strategies that integrate emotional and technological dimensions in navigating the intricacies of modern investment landscapes. As the synergy between human intuition and artificial intelligence becomes increasingly integral to financial decision-making, this study contributes to the ongoing discourse on the symbiotic relationship between minds and machines in investments.0
Bronchopulmonary cancers are common cancers with a poor prognosis. It is the leading cause of death by cancer in Algeria and in the world. Behind this unfavorable prognosis hides numerous disparities according to age, sex, and exposure to risk factors, ranking 4th among incident cancers and developing countries including Algeria, all sexes combined. It ranks 2nd cancers in men and 3rd among women. Whatever the age observed, the incidence of this cancer is higher in men than in women, however the gap is narrowing to the detriment of the latter. The results of scientific research agree to relate trends in incidence and mortality rates to tobacco consumption, including passive smoking. Furthermore, other risk factors are mentioned such as exposure to asbestos in the workplace or to radon for the general population, or even genetic predisposition. However, the weight of these etiological and/or predisposing factors is in no way comparable to that of tobacco in the genesis of lung cancer and the resulting mortality. We provide a literature review in our article on the descriptive and analytical epidemiology of lung cancer.

Haphazard and low soil fertility, low yielding verities and poor agronomic practices are among the major factors constraining onion production in the central rift valley of Ethiopia. Therefore, a field experiment was conducted in East Showa Zone of Adami Tulu Jido Combolcha district in central rift valley areas at ziway from October 2021 to April 2022 to identify appropriate rate of NPSB fertilizer and planting pattern of onion varieties. The experiment was laid out in split plot design of factorial arrangement in three replications. The main effect of NPSB blended fertilizer rates and varieties (red coach and red king) significantly (p<0.01) influenced plant height, leaf length, leaf diameter, leaf number and fresh leaf weight, shoot dry matter per plant, and harvest index. Total dry biomass, bulb diameter, neck diameter, average fresh bulb weight, bulb dry matter, marketable bulb yield, and total bulb yield were significantly (p<0.01) influenced only by the main effect of NPSB blended fertilizer rates. In addition, unmarketable bulb yield was statistically significantly affected (p≥0.05) by the blended fertilizer rates and planting pattern. Moreover, days to 90% maturity of onion was affected by the main factor of NPSB fertilizer rate, variety and planting pattern. The non-fertilized plants in the control treatment were inferior in all parameters except unmarketable bulb yield and harvest index. Significantly higher marketable bulb yield (41 t ha-1) and total bulb yield (41.33 t ha-1) was recorded from 300 kg ha-1 NPSB blended fertilizer rate applied. Double row planting method and hybrid red coach onion variety had also gave higher growth and yields. The study revealed that the highest net benefit of Birr, 878,894 with lest cost of Birr 148,006 by the combinations of 150 kg blended NPSB ha-1 with double row planting method (40cm*20cm*7cm) and red coach variety which can be recommendable for higher marketable bulb yield and economic return of hybrid onion for small scale farmers in the study area. Also, for resource full producers (investors), highest net benefit of Birr 1,205,372 with higher cost (159,628 Birr) by application of 300 kg NPSB ha-1 is recommended as a second option. However, the research should be replicated both in season and areas to more verify the recommendations.

The ethanolic extract of canarium solomonense leaves (ecsl) was studied for its neuroprotective activity. The neuroprotective activity of ECSL was found to have a significant impact on neuronal cell death triggered by hydrogen peroxide (MTT assay) in human SH-SY5Y neuroblastoma cells. Scopolamine, a muscarinic receptor blocker, is frequently used to induce cognitive impairment in laboratory animals. Injections of scopolamine influence multiple cognitive functions, including motor function, short-term memory, and attention. Using the Morris water maze, the Y maze, and the passive avoidance paradigm, memory enhancing activity in scopolamine-induced amnesic rats was evaluated. Using the Morris water maze, the Y maze, and the passive avoidance paradigm, ECSL was found to have a substantial effect on the memory of scopolamine- induced amnesic rats. Our experimental data indicated that ECSL can reverse scopolamine induced amnesia and assist with memory issues.
The goal of neuroprotection is to shield neurons against damage, whether that damage is caused by environmental factors, pathogens, or neurodegenerative illnesses.

In the current digital landscape, cybercriminals continually evolve their techniques to execute successful attacks on businesses, thus posing a great challenge to information technology (IT) professionals. While traditional cybersecurity approaches like layered defense and reactive security have helped IT professionals cope with traditional threats, they are ineffective in dealing with evolving cyberattacks. This paper focuses on the need for a proactive cybersecurity culture among IT professionals to enable them combat evolving threats. The paper emphasis that building a proactive security approach and culture can help among IT professionals anticipate, identify, and mitigate latent threats prior to them exploiting existing vulnerabilities. This paper also points out that as IT professionals use reactive security when dealing with traditional attacks, they can use it collaboratively with proactive security to effectively protect their networks, data, and systems and avoid heavy costs of dealing with cyberattack’s aftermaths and business recovery.
The Impacts of Viral Hepatitis on Liver Enzymes and BilrubinAI Publications
Viral hepatitis is an infection that causes liver inflammation and damage. Several different viruses cause hepatitis, including hepatitis A, B, C, D, and E. The hepatitis A and E viruses typically cause acute infections. The hepatitis B, C, and D viruses can cause acute and chronic infections. Hepatitis A causes only acute infection and typically gets better without treatment after a few weeks. The hepatitis A virus spreads through contact with an infected person’s stool. Protection by getting the hepatitis A vaccine. Hepatitis E is typically an acute infection that gets better without treatment after several weeks. Some types of hepatitis E virus are spread by drinking water contaminated by an infected person’s stool. Other types are spread by eating undercooked pork or wild game. Hepatitis B can cause acute or chronic infection. Recommendation for screening for hepatitis B in pregnant women or in those with a high chance of being infected. Protection from hepatitis B by getting the hepatitis B vaccine. Hepatitis C can cause acute or chronic infection. Doctors usually recommend one-time screening of all adults ages 18 to 79 for hepatitis C. Early diagnosis and treatment can prevent liver damage. The hepatitis D virus is unusual because it can only infect those who have a hepatitis B virus infection. A coinfection occurs when both hepatitis D and hepatitis B infections at the same time. A superinfection occurs already have chronic hepatitis B and then become infected with hepatitis D. The aim of this study is to find the effect of each type of viral hepatitis on the bilirubin (TB , DSB) , and liver enzymes; AST, ALT, ALP,GGT among viral hepatitis patients. 200 patients were selected from the viral hepatitis units in the central public health laboratory in Baghdad city, all the chosen cases were confirmed as a positive samples , they are classified into four equal group each with fifty individual and with a single serological viral hepatitis type either; anti-HAV( IgM ) , HBs Ag , anti-HCV ,or anti-HEV(IgM ). All patients were tested for; serum bilirubin ( TB ,D.SB ) , AST , ALT , ALP , GGT. Another fifty quite healthy and normal person was selected as a control group for comparison. .

Determinants of Women Empowerment in Bishoftu Town; Oromia Regional State of ...AI Publications
The purpose of this study was to determine the status of women's empowerment and its determinants using women's asset endowment and decision-making potential as indicators. To determine representative sample size, this study used a two-stage sampling technique, and 122 sample respondents were selected at random. To analyze the data in this study, descriptive statistics and a probit model were used. The average women's empowerment index was 0.41, indicating a relatively lower status of women's empowerment in the study area. According to the study's findings, only 40.9% of women were empowered, while the remaining 59.1% were not. The probit model results show that women's access to the media, women's income, and their husbands' education status have a significant and positive impact on the status of women's empowerment, while the family size of households has a negative impact. As a result, it is important to enhance women's access to the media and income, promote family planning and contraception, and improve men's educational status in order to improve the status of women's empowerment.
The Comparison of Ticket Performance of Existing and Proposed TPRCA SystemAI Publications
This document summarizes a research study that compared the ticket performance of existing and proposed Ticket Performance Root Cause Analysis (TPRCA) systems for IT infrastructure management. The study found that the proposed TPRCA system, which uses domain-driven data mining and incorporates root cause analysis and continuous improvement processes, resulted in higher ticket processing rates and better resolution of issues compared to the existing system. Specifically, the proposed system reduced processing times, classified tickets by issue type to aid resolution, identified root causes of high problem tickets, and implemented solutions to reduce future ticket volumes. A trial implementation in two banking sectors supported these findings.

strengths and weaknesses, so the application must be
adapted to the needs of the analysis.
Analysis with the LES model cannot describe
consumer demand behavior according to Engel's law
(Nugroho & Suparyono, 2015). The LES model is only
capable of analyzing normal and superior commodities
(Maula et al., 2019). Meanwhile, the Rotterdam model is
inconsistent with the utility maximization function (Delavar
et al., 2020). So that neither the LES model nor the
Rotterdam model is suitable for the analysis of food demand
because both models do not meet the assumptions of the law
of demand. One alternative demand system model that can
be used for food analysis is the ITS and LA-AIDS models.
Both of these models can explain the system demand
flexibly and better describe the empirical conditions.
However, the ITS model requires a relatively high number
of independent parameters for analysis, so it is not suitable
when applied to secondary data. The most suitable system
demand model for food analysis is the LA-AIDS model.
The LA-AIDS model is linear in parameters and simpler in
analysis (Deaton, A., & Muellbauer, J., 1980; Sulgham,
2006; Liao and Chern, 2007).
Another advantage of the LA-AIDS model is that the
resulting price coefficient can be used to calculate three
kinds of elasticity, namely (1) own price elasticity, (2)
cross-price elasticity, and (3) expenditure elasticity
(Akinbode, 2015; Delport, M., et al, 2017; M.J.A. Van den
Tillaart, 2019; Bett et al., 2012). Further information on the
value of the elasticity of demand can be applied to the
estimation of demand for staple food. Analysis of the
estimated demand for staple food has been carried out by
several researchers, such as the analysis of demand for rice
and other commodities in the Philippines (Sombilla, M. A.,
Lantican, F. A., & Quilloy, K. P., 2013), demand for rice in
Nigeria (Kassali, R., Kareem, R. O., Oluwasola, O., &
Ohaegbulam, O. M., 2010; Erhabor, P. O. I., & Ojogho, O.,
2011; Oyinbo, O., Omolehin, R. A., & Abdulsalam, Z.,
2013). Analysis of staple food demand is also carried out in
China (Zheng and Henneberry, S.R., 2010a; Zheng, Z., &
Henneberry, S. R., 2010b), The results of the analysis
explain that there are differences in household behavior
based on social and demographic factors such as the number
of household members and region. Therefore, each analysis
is important to distinguish social and demographic factors
in the analysis.
Food analysis, especially staple food in Indonesia,
has been carried out by several researchers, such as food
demand in East Java (Purwaningsih, Y., Hartono, S.,
Masyhuri, M., & Mulyo, J. H., 2014), National food demand
(Pangaribowo, E.H. and Tsegai, D. W., 2011; Sa’diyah, A.
A., Nendissa, D. R., & Sinaga, A. M., 2019), food demand
in East Kalimantan (Sunaryati, R., 2016). The problem that
is often faced by researchers is the value of zero
consumption, thus causing biased results in econometric
analysis. The zero consumption value solution can be solved
by grouping the commodity with similar commodities (Cox
dan Wohlgenant, 1986). Apart from grouping commodities,
the problem of zero consumption can also be overcome
using the Inverse Mill's Ratio (IMR) approach in the
analysis. IMR is the ratio of the estimated value of the
standard normal density function to the estimated value of
the standard normal cumulative distribution function (Heien
dan Wessells, 1990).
Currently, the analysis of staple foods is still needed
(Muyanga et al., 2006). Staple food as a source of
carbohydrates has an important role in human life,
especially in developing countries such as Indonesia.
According to Rachman and Ariani (2008); Amanto et al.,
2019; Hafizah et al., (2020), food consumption in Indonesia
is still dominated by food sources of carbohydrates,
especially rice. The demand for rice will continue to
increase in line with population growth in Indonesia which
is increasing every year (Badan Pusat Statistik, 2017a;
Bashir & Yuliana, 2018). This condition causes the price of
rice to increase if it is not balanced with an increase in
production. If rice production cannot be increased, the effort
that can be done is to diversify local food products such as
corn, cassava, and sweet potatoes. Analysis of staple foods
with a demand system is expected to be able to provide
information about the relationship between rising rice prices
as the main staple food source and local diversified
commodities. According to Ariani (2010), diversification of
staple food commodities has started to occur, but what has
happened is that rice diversification is more not with local
commodities but with wheat flour which is a non-local food
commodity. Diversification of rice to flour will cause other
problems, namely the increase in the value of wheat flour
imports. This condition causes the need for an analysis of
the linkage of rice as the main food commodity with local
and non-local commodities (wheat flour). This study aims
to: (1) analyze the estimated demand for carbohydrate-
sourced food, (2) analyze the demand for food-carbohydrate
sources in rural households, (3) analyze the demand for
food-carbohydrate sources in urban households.
II. METHODS
The research uses data from the 2016 National Socio-
Economic Survey (Susenas). The Susenas data required
includes the Consumption and Expenditure module at the
household level in the province of Central Java for March
2016. The data is obtained from the Central Statistics
Agency (BPS). Central Java Susenas data in 2016 consisted
3. Anindita et al. International Journal of Horticulture, Agriculture and Food Science (IJHAF)
6(2)-2022
https://aipublications.com/ijhaf/ Page | 13
of 11,796 rural households and 10,994 urban households.
The core data needed in this study include the status of
residence (city/village) and the number of household
members. Meanwhile, the consumption module data needed
is a description of household expenditures for rice, corn,
cassava, sweet potato, and wheat flour commodities.
Analysis of food demand for carbohydrate sources
was carried out using the Linear Approximation/Almost
Ideal Demand System (LA-AIDS) model. The LA-AIDS
model is a linear demand model derived from Marshallian
demand but in the proportion of expenditure or budget share
(Deaton dan Muellbauer, 1980). The LA/AIDS model was
estimated using the Seemingly Unrelated Regression /SUR
(Siami-Namini, 2017; Essaten, S., Mekki, A. A. E., &
Serghini, M., 2018). SUR is an estimate in a multivariate
regression system that explains the value of each unrelated
equation model. So that each equation model can be
analyzed simultaneously without causing a correlation
between the models (Zellner, 1962). Here are the
similarities of LA-AIDS:
𝑤𝑖 = 𝛼𝑖 + ∑ 𝛾𝑖𝑗 log 𝑝𝑗
𝑗 + 𝛽𝑖 log(𝑥 𝑝
⁄ ∗) + 𝛽𝑖 log 𝐴𝑅𝑇𝑗 +
𝜇𝑖 ............................................. (1)
The household consumption data from the Susenas is
household consumption for one week. The short
consumption time causes some households not to consume
(zero consumption). This condition causes the results of the
OLS analysis to be biased (Busway, et al, 2007). To avoid
the problem of bias in the analysis, Heckman (1979) uses
the predictive value of the probit model that produces the
Inverse Mill's Ratio (IMR). IMR is the ratio of the estimated
value of the standard normal density function to the
estimated value of the cumulative standard normal
distribution function. The IMR value is obtained from the
following equation:
𝐼𝑀𝑅𝑖ℎ =
∅(𝑥,𝛽)
𝜃(𝑥,𝛽)
𝑓𝑜𝑟 𝑦𝑖ℎ = 1
............................................................................................
(2)
𝐼𝑀𝑅𝑖ℎ =
∅(𝑥,𝛽)
𝜃(𝑥,𝛽)
𝑓𝑜𝑟 𝑦𝑖ℎ = 0
...............................................................................................
. (3)
Where x is the socio-demographic factor, 𝛽 is the log
of commodity prices. 𝑦𝑖ℎ is a dummy variable, 𝑦𝑖ℎ = 1 if
the household consumes the commodity and, 𝑦𝑖ℎ = 0 if the
household does not consume the commodity.
Heien and Wessells (1990) used Heckman's two-step
estimation by including IMR in the observations. So that the
LA-AIDS equation is obtained as follows:
𝑤𝑖 = 𝛼𝑖 + ∑ 𝛾𝑖𝑗 log 𝑝𝑗
𝑗 + 𝛽𝑖 log(𝑥 𝑝
⁄ ∗) + 𝛽𝑖 log 𝐴𝑅𝑇𝑗 +
𝐼𝑀𝑅𝑗 + 𝜇𝑖 ................................... (4)
Where 𝑤𝑖 is the ith
food expenditure share; 𝑝𝑗 is the jth
commodity price; x is total food expenditure; IMR is the
value of Inverse Mills Ratio; α, d, β, 𝛾 are estimation
parameters, and μ are error terms. p* is the stone price index
(ln 𝑝∗
= Σ𝑤𝑖. ln 𝑝𝑖). While i, j for 1 (rice), 2 (corn), 3
(cassava), 4 (sweet potato), 5 (wheat flour). The LA-AIDS
model to be consistent with the demand theory, the use of
the AIDS model in the demand system must go through a
demand restriction test consisting of adding up,
homogeneity, and symmetry. (Liao dan Chern, 2007).
Adding up : ∑ 𝑎𝑖 = 1

𝑖 , ∑ 𝑏𝑖 = 0
𝑖 ,
Homogenitas : ∑ 𝑐𝑖𝑗 = 0

Simetri : 𝑐𝑖𝑗 = 𝑐𝑗𝑖.
The results of the model estimation with LA-AIDS
are used to calculate the elasticity of demand. This analysis
uses two approaches in calculating the elasticity of demand,
namely the compensated (Hicksian) approach, and the
uncompensated (Marshallian) approach. These two
approaches are used because they have different effects
namely, there is a substitution effect in the compensated
analysis, while in the uncompensated analysis, apart from a
substitution effect, there is also a real income effect
(Nicholson, 1995; Crosetto, 2010).

III. RESULT AND DISCUSSION
1.1. Estimation of Food Demand for Carbohydrate
Sources
Respondents from Central Java Susenas data in 2016
consisted of 22,838 households. Of the total number of
respondents, 51.76% of households live in rural areas and
48.24% of households live in urban areas. According to the
Central Statistics Agency (2017a), household consumption
of rice in rural areas (1,494 kg/capita) is greater than in
urban areas (1,344 kg/capita), which means that households
in rural areas are more dependent on demand for rice as the
main food ingredient than in urban areas. Several factors
influence the size of household consumption in both rural
and urban areas, including prices, household expenditures,
and the number of household members. The effect of each
variable can be seen in Table 1.

All observation variables in Table 1 have a
probability value of less than one percent. This means that
all independent variables have a significant effect on
changes in commodity demand. The significant value of the
price and expenditure coefficients can be used to analyze
the sensitivity of household consumption to changes in
prices and expenditures. The analysis is carried out through
an analysis of the elasticity of demand in the form of an
analysis of own price elasticity, cross price elasticity, and
expenditure elasticity.
Table 1 shows the coefficient for the size of
household members, some are positive and some are
negative. Positive and negative signs explain the effect of
the number of household members on the increase and
decrease in demand for commodities. The coefficient on the
number of household members has a positive effect on each
share of rice expenditure and negatively on the share of
wheat, sweet potato, and cassava expenditures. However,
the size of household members has a different effect on the
share of maize expenditure, which is positive in the rural
analysis and negative in the urban analysis.
1.2. The Elasticity of Food Demand for Carbohydrate
Sources in Rural Areas
Analysis of elasticity of demand is carried out to determine
the level of sensitivity of demand for a commodity to
changes in expenditure and changes in commodity prices.
Expenditure elasticity describes the behavior of households
towards the demand for a commodity due to changes in
household spending. Meanwhile, marginal expenditure
share is used to determine changes in the share allocation of
commodity expenditures in the future due to changes in
household expenditures (Andreyeva et al., 2010; Hursh, S.
R., & Roma, P. G., 2016; Asare dan Eghan, 2012; Wogbe,
2000). Own price elasticity explains the effect of changes in
5. Anindita et al. International Journal of Horticulture, Agriculture and Food Science (IJHAF)
6(2)-2022
https://aipublications.com/ijhaf/ Page | 15
commodity prices on the demand for these commodities.
Meanwhile, cross price elasticity describes the relationship
formed between commodities when one of them
experiences a price change (Elnovita et al., 2019;
Hirshleifer, 1985; Anindita, 2008). The results of the
analysis of expenditure elasticity and marginal expenditure
share are presented in Table 2. While the results of the
analysis of own price elasticity and cross price elasticity are
uncompensated and compensated in Table 3.
Table 2. Expenditure Elasticity and Marginal Expenditure share in Rural households
Commodity Expenditure Elasticity Marginal expenditure share
Rice 0.9921 1.0180
Corn 0.9986 0.8819
Wheat Flour 1.0092 0.6886
Sweet Potato 1.0254 0.2060
Cassava 1.0012 -1.7946
Source: Author’s calculations from Susenas.
The elasticity of the six commodities (rice, corn,
wheat, sweet potato, cassava) has a positive between 0.9921
to 1.0254 (Table 2). The positive value of the expenditure
elasticity illustrates that an increase in household spending
can increase the demand for a commodity (Sa’diyah et al.,
2019; Hirshleifer, 1985; Tomek, W. G., & Kaiser, H. M.,
2014; Nendissa, D. R., Anindita, R., Khoiriyah, N., &
Sa’diyah, A. A., 2021). Rice has a lower elasticity value
than other commodities. This means that among other
commodities, rice is the main source of carbohydrates
because the value of the change in demand is lower than the
change in expenditure of 0.9921. This condition is rice
consumption has become the main source of carbohydrate
food consumption so changes in household spending do not
have a major influence on rice consumption for rural
households. In addition to rice, the commodity that has an
elasticity value of less than one is corn, which is 0.9986.
Meanwhile, other commodities have expenditure elasticity
values of more than one, namely 1.0092 (wheat), 1.0254
(sweet potato), and 1.0012 (cassava). The results of this
analysis support another analysis which states that the
elasticity of rice expenditure in rural Indonesia is lower than
other carbohydrate sources (Saliem, 2002; Miranti, 2017).
The marginal expenditure share for rice is 1.0180
(greater than one). This large value indicates that in the
future only rice will receive a larger increase in expenditure
allocation compared to other commodities. Meanwhile, for
other commodities, the marginal expenditure share is
around 0.2060-0.8819. The interesting thing is the marginal
expedited value of cassava is -1.7946. This means that in the
long term there will be a decrease in the allocation of
expenditure to consume cassava. Even though cassava is
one of the local commodities which is an alternative food
from the government's efforts to diversify rice (Ariani,
2010; Rahmawati, 2009; Sasongko, L. A., 2009).

The uncompensated or Marshallian price elasticity
(Table 3) in rural areas has a negative for each carbohydrate.
This result is following the theory of demand, namely the
demand for a commodity will decrease when there is an
increase in the price of the commodity or it is called
downward sloping (Varian, 2010; Febianti, Y. N., 2014;
Sudarmanto, E., Syaiful, M., Fazira, N., Hasan, M.,
Muhammad, A., Faried, A. I., & Purba, B., 2021). The
elasticity own price of rice, corn, and cassava are -0.9962; -
0.9645; -0.9938, including the category of a commodity that
is inelastic to price changes, where the value of the change
in demand is not greater than the price change. Meanwhile,
the own price elasticity of flour and sweet potato are -1.0032
and -1.0139, including commodity categories that are elastic
to price changes, which means that the value of changes in
demand is greater than changes in commodity prices. If
viewed on a compensated or Hicksian own price elasticity
basis (in Table 3), the price elasticity of each commodity in
rural areas also has a negative, except for positive rice.
Almost all commodities in the compensated analysis have
an elasticity of less than one (-0.0218 to -0.8079). This
explains that these commodities are included in
commodities that are inelastic to price changes. Different
conditions occur in cassava which is elastic to price changes
because it has more than one elasticity, which is 2.7885.
The results of the uncompensated cross-elasticity
analysis show that rice has a substitution relationship with
other commodities except for maize which has a
complementary relationship. Corn has a substitution
relationship with other commodities except for rice. Wheat
has a substitution relationship with sweet potato and cassava
and has a complementary relationship with rice and corn.
Sweet potato has a substitution relationship with rice and
cassava, while with corn and wheat it has a complementary
relationship. Cassava with other commodities has a
complementary relationship except with rice. Although the
relationship formed between commodities has differences,
the magnitude of the value given from the impact of changes
in commodity prices on other commodities overall has a
value of less than one or is inelastic to changes in the prices
of other commodities. If analyzed on a compensated basis,
the cross price elasticity of food demand in rural areas
almost all commodities have a complementary relationship
with other commodities. In contrast to other commodities,
cassava has a substitution relationship with other
commodities. Meanwhile, if viewed from the magnitude of
the change in value, only changes in the price of rice and
cassava provide changes in inelastic demand for other
commodities. The results of this study are following the
results of BPS research (2009) .
The difference in the results of the uncompensated
analysis with the compensated analysis explains that there
is an influence given by the income effect on the
uncompensated analysis. So that when an analysis is carried
out without an income effect (compensated) it can provide
different results, both from substitution to complementary
relationships and vice versa (Anindita, 2008).
1.3. The Elasticity of Food Demand for Carbohydrate
Sources in Urban
The elasticity of demand for food sources of carbohydrates
in urban areas is also carried out with three analyzes, namely
expenditure elasticity, price elasticity, and cross elasticity.
In addition, marginal expenditure share analysis was also
carried out. As in rural areas, the elasticity of demand
analysis in urban areas is carried out using two approaches,
namely the uncompensated or Marshallian approach and the
compensated or Hicksian approach. The analysis of
expenditure elasticity and marginal expenditure share in
urban areas is presented in table 4, while the results of the
analysis of price elasticity and cross elasticity are presented
in table 5.
Table 4. Expenditure Elasticity and Marginal Expenditure Share of Food Demand in Urban Areas

Rice 0.9846 1.1171
Corn 0.9656 0.0269

The expenditure elasticity (Table 4) shows that rice,
corn, wheat flour, sweet potato, and cassava are normal
goods because they have elacticity less than one. This
means that an increase in household spending can increase
the demand for these commodities. The elasticity of
household expenditure in urban areas is between 0.9650 to
0.9923. Wheat flour is included in a superior (luxurious)
commodity with an elasticity of more than one, which is
1.0291. This means that the allocation of urban household
expenditures for wheat flour consumption is higher than for
other commodities when there is an increase in income
(Lantican et al, 2013). This condition needs attention from
the government. Given that flour is an imported product.
The value of the marginal expenditure share of rice
commodities in urban areas is the highest compared to the
other four commodities (corn, flour, cassava, and cassava).
This means that the value of the increase in the allocation of
rice expenditure in the future is the highest compared to
other commodities, amounting to 1.1171. Meanwhile, other
commodities ranged in value from 0.0269 to 0.3229. If rice
expenditure allocation increases, sweet potato, and cassava
experience a decrease in expenditure allocation for urban
households by -0.1974 (sweet potato) and -0.2695
(cassava).

Uncompensated own price elasticity in urban areas
shows that each commodity has a negative elasticity value
according to the theory of demand, an increase in
commodity prices can reduce demand for these
commodities. In urban areas, commodities that are inelastic
to price changes are rice (-0.9490), wheat (-0.9868), and
sweet potato (-0.9986). Rice is the most responsive
commodity to price changes because it has the lowest
inelastic. Meanwhile, commodities that have an elastic
elasticity are maize (-1.1528) and cassava (-1.0057). The
results of the elastic analysis explain that the value of the
change in demand is greater than the value of the in the price
change. If analyzed on a compensated basis, the price
elasticity in urban areas has the same results as the analysis
in rural areas, namely that all commodities have negative
values except for rice commodities. Each commodity has a
different response to any changes in commodity prices. Rice
and wheat are inelastic to price changes, while corn, sweet
potato, and cassava are elastic to price changes.
Analysis of uncompensated cross price elasticity in
urban areas explains that the relationship between rice and
corn and wheat is a substitution, while the relationship with
sweet potato and cassava is complementary. Corn has a
complementary relationship with all commodities except
cassava. Wheat has a substitution relationship with corn and
cassava and has a complementary relationship with rice and
sweet potato. Sweet potato and cassava have a
complementary relationship with rice and wheat.
Meanwhile, with other commodities, sweet potato has a
substitution relationship. The analysis of compensated cross
price elasticity in urban areas explains that the relationship
formed between commodities is complementary to rice and
other commodities, corn to other commodities, and flour to
other commodities. Meanwhile, sweet potato and cassava
have a substitution relationship with other commodities.
The value of the effect of changes in the price of a
commodity with other commodities having a high influence
is when a change in the price of rice affects the demand for

flour (1.1568), sweet potato (1.1430), and cassava (1.1309).
While the change value for other commodities does not
reach one or means that the relationship formed is inelastic.
IV. CONCLUSIONS AND RECOMMENDATIONS
The demand for food sources of carbohydrates has
differences between rural and urban households which are
influenced by several things, including price, income, and
number of household members. When viewed from the
elasticity of demand, rice and corn are commodities that are
inelastic to changes in household expenditure. Wheat is a
superior commodity in both rural and urban areas.
Meanwhile, sweet potato and cassava are elastic in terms of
expenditure for rural households. However, each household
allocates higher consumption expenditures for rice
compared to other commodities. In line with the expenditure
elasticity analysis, rice has the most inelastic price elasticity
value compared to other commodities. In addition, the effect
of changes in rice consumption on changes in prices of other
commodities is lower than the effect of changes in rice
prices on the consumption of other commodities. This
condition explains that among other commodities, the
demand for rice to meet the needs of carbohydrates in the
household is the highest. So that effort are needed from the
government to maintain the stability of rice commodity
prices in the market.
