potassium were examined at the end of composting. Moisture be maintained in higher level, than 70%. Carbon
to nitrogen ratio of 30 :1 was experimented.
Biogas Synthesis as Means of Solid Waste Management in Kampala, UgandaScientific Review SR
Cattle dung, cooked food waste, and chicken droppings mixed with coffee husks have been used separately and also as mixtures to form anaerobic digestion slurries in a bid to treat to degrade the organic fractions of these wastes and recycle the bio-fertilizer after recovering biogas. Single and mixed substrate slurries evolved significant quantities of methane within 27days together with reduced mass of soil conditioner. The volume of biogas formed in cogeneration mixtures were higher than for single substrate digestion due to the C/N ratio shifting to near 30:1 as a result of mixing. So degradation of organic pollutants was higher in mixed substrate digestion mixtures. Our study yielded average volumes ranging from 315 to 435+ 5.65.mL/L which was in agreement with what is in literature. Digestion of cattle dung, cooked waste foods, and droppings of chicken and mixed substrate slurries using sludge inoculums was very effective in degrading solid waste from homes, thus detoxifying it to bio-fertilizers. Although both single and mixed substrate digestion of waste yielded high enough volumes of biogas; digestion of slurry of mixed organic solid waste substrates is better method of waste management. Digestion of garbage from Kampala should be tested at macro levels at both ambient and mesophilic temperatures. There is need to try out the garbage digestion experiments in the semi-arid towns as well as very cold towns in Uganda.

A greenhouse study was conducted to assess the potential of green waste wood ash compost on a tropical acid soil. Four types of compost (prepared with 0, 5, 10 and 15% of wood ash prior composting) were used to amend an Oxisol from the centre region of Cameroon. The different composts were mixed with the soil in 1/4 proportions (w/w); the experimental design was a completely randomized block with three replicates per treatment. The different treatments were planted with soybean (Glycine max L.) for three month growing period. Compost amendment increased the soil pH, organic carbon, total nitrogen and total phosphorus. Bacterial and fungal biomass together with cellulase and protease activities also increased in amended soil. Following soil chemical, physical and chemical parameters, plant growth and yield also improved in compost treated sols. However, compost prepared with 15% wood ash additive showed trends of inhibition of the soil microbiota. It can be concluded that green waste wood ash compost could be used as a suitable soil fertilizer for tropical acid soils, although precautions are to be taken when using these composts prepared with addition of wood ash ≥ 15%.

This study was focused on the effects of Sugarcane Bagasse Ash (SCBA) additive on process parameters and compost quality of Co-composting of filter cake and bagasse. Filter cake and bagasse were mixed and sugar cane bagasse ash (SCBA) from a heating power plant of sugar mill. Three compost mixes (M) were obtained: MA with 0%, MB with 10% and MC with 20 wt % of fuel ash. These three different mixes were composted in an experimental composter as three parallel experiments for 3 weeks each. The physical, chemical and biological parameters were monitoring during composting. Significantly, ash additives decreased the total organic carbon; measured by mineralization the breaking down of the organic matter was more rapid in the MC than in the MA, as well as increased the pH during composting. Interesting, the pH decreased was most important in MA and attend 5 for the first week of composting, and then it gradually increased to pH around 8 at the end of the process. The results indicated that ash inhibits the pH drop due to production of organic acids during composting. The acidity of the material was reported as affects the process during the initial phase of rising temperature and quality of the final product. The temperature reached up to 50-55oC during thermophilic phase, the greater temperature was obtained for MC. At the end of composting, the electrical conductivity increased in the MC, especially in MC, but don’t exceed limit (4 mS/cm) for prevent phytotoxicity of the compost. The SCBA additive was likely to speed up the composting process of bagasse with filter cake from 44 days to 33 days.

Abstract— This research was carried out in order to utilize mud cake from sugar factory and cattle feces waste to make compost. Composting process was accelerated by addition of isolate called Trichoderma viride APT01. The study was conducted according to a completely randomized design with three replications with mud cake and cattle feces ratio: 100/0, 75/25, 50/50, 25/75, and 0/100. Each mixture of organic matter was added with isolate of Trichoderma viride APT01. Quantitative data was analyzed using variance analysis with alpha 0:05. Among those compositions, it was shown that the value of C / N ratio between 14.6 to 18.3 with the level of acidity, pH 6.62 to 7.36 was the best product. Compost produced for composition of mud cake and cattle feces 25/75 has a value of C/N = 14.6 and pH = 6.78. This result was in accordance with The Bureau of Indian Standards.

Acceleration of Lead Phytostabilization by Maize (Zea mays) in Association wi...Agriculture Journal IJOEAR
Abstract— Soil where shooting practices are conducted is extremely contaminated with heavy metals, exclusively by Pb, due to the bullets and bullet fragments. These extreme concentrations of Pb, generate an unfavourable surroundings for agriculture and human health through phytoaccumulation. This study was conducted to assess the possibility of particular bio-amendment, phytostabilization on the reduction of bioavailable Pb in such contaminated soil. Biomass (BM) produced from Gliricidiasepium was used to see its ability to be used in soil remediation together with Maize (Zea mays) as phytostabilizer. A pot experiment was conducted with Maizeby adding BM at three different percentages, 1, 2.5 and 5% (w/w). Soil without amendments served as the control and arranged in a complete randomized design. By maize, translocation rate of heavy metals into crop were determined. After sixth week, grown maize were harvested and analyzed followed by digestion with con.HNO3. The most significant immobilization (p<0.05)>TF in maize. For the treatment 5% BM, PF and TF for Pb are 1.22 and 0.15 respectively. Thereby maize can be considered as a potential phytostabilizer. At the same time efficiency of phytostabilizing nature of maizecan increase together with the application of soil amendment – BM.
Optimization of Experimental Biomethanation Applied to Poultry Droppings for ...IJEAB
The fight against climate change is first and foremost passed by the reduction of greenhouse gases (GHG). Mainly in the form of methane CH4, the GHGs emitted by the waste originate from the decomposition of organic matter which is more commonly known as Anaerobic Digestion (AD) or Biomethanation. Livestock manure is one of the major hazards to the environment and human health due to the nuisances and pollution generated. The present study consists of optimizing the methane fermentation applied to poultry droppings. This optimization focuses on the daily monitoring of experimental digesters, on the physico-chemical characterization of the inputs used and on the study of the effect of temperature and inoculum changes on the daily production of biogas and its composition (CH4, CO2 and H2S). The main results show, on the one hand, that the stability of the DA process after initial filling depends on experimental conditions, the general characteristics of the anaerobic digester, the initial biomass activity and the nature of the introduced inoculum. On the other hand, the production of biogas is better at a temperature of 35°C than at a temperature of 55°C and the addition of the inoculum has improved the production of biogas and the CH4 content, especially the use Of liquid poultry digestate.

Cars are a very important part of this modern world because they give luxury and comfort. Even
though they are comfortable, some problems always keep arising on the safety side. After a lot of research they
rectified certain problems using air bags, auto parking, turbo charger, pedal shift…, etc.
And now we are going to discuss about one such problem that arises on the safety side. An unsuspected
accident occurs when people smash their fingers in between the car doors. Due to this kind of accident around
120,000 people are injured every year. But this was not taken as a very major safety concern for the customer.
To avoid this kind accident due to car doors, we are introducing “SAFETY DOOR LOCK SYSTEM”
with the help of “HYDRAULIC PISTON AND IR SENSORS”.
The major working process of the “SAFETY DOOR LOCK SYSTEM”is, when a person places his/her
hand or fingers in the gap between the door and the outer panel, at the time when the closing action of the door
takes place, the Sensors start to transmit the Infra Red Rays to the Receivers at the
other end, and so even if someone closes the door without anybody‟s knowledge the hydraulic piston will
automatically come out and stop the door from closing and prevent the person from the unsuspected accident
and minor injuries by the car door and ensure maximum safety to the customer.
Extrusion can be defined as the process of subjecting a material to compression so that it is forced to
flow through an opening of a die and takes the shape of the hole. Multi-hole extrusion is the process of
extruding the products through a die having more than one hole. Multi-hole extrusion increases the production
rate and reduces the cost of production. In this study the ram force has calculated experimentally for single hole
and multi-hole extrusion. The comparison of ram forces between the single hole and multi-hole extrusion
provides the inverse relation between the numbers of holes in a die and ram force. The experimental lengths of
the extruded products through the various holes of multi-hole die are different. It indicates that the flow pattern
is dependent on the material behavior. The micro-hardness test has done for the extruded products of lead
through multi-hole die. It is observed that the hardness of the extruded lead products from the central hole is
found to be more than that of the products extruded from other holes. The study suggests that multi-hole
extrusion can be used for obtaining the extruded products of lead with varying hardness. The micro-structure
study has done for the lead material before and after extrusion. It is observed that the size of grains of lead
material after extrusion is smaller than the original lead.
Analysis of Agile and Multi-Agent Based Process Scheduling Modelirjes
As an answer of long growing frustration of waterfall Software development life cycle concepts,
agile software development concept was evolved in 90’s. The most popular agile methodologies is the Extreme
Programming (XP). Most software companies nowadays aim to produce efficient, flexible and valuable
Software in short time period with minimal costs, and within unstable, changing environments. This complex
problem can be modeled as a multi-agent based system, where agents negotiate resources. Agents can be used to
represent projects and resources. Crucial for the multi-agent based system in project scheduling model, is the
availability of an effective algorithm for prioritizing and scheduling of task. To evaluate the models, simulations
were carried out with real life and several generated data sets. The developed model (Multi-agent based System)
provides an optimized and flexible agile process scheduling and reduces overheads in the software process as it
responds quickly to changing requirements without excessive work in project scheduling.
Effects of Cutting Tool Parameters on Surface Roughnessirjes
This paper presents of the influence on surface roughness of Co28Cr6Mo medical alloy machined
on a CNC lathe based on cutting parameters (rotational speed, feed rate, depth of cut and nose radius).The
influences of cutting parameters have been presented in graphical form for understanding. To achieve the
minimum surface roughness, the optimum values obtained for rpm, feed rate, depth of cut and nose radius were
respectively, 318 rpm, 0,1 mm/rev, 0,7 mm and 0,8 mm. Maximum surface roughness has been revealed the
values obtained for rpm, feed rate, depth of cut and nose radius were respectively, 318 rpm, 0,25 mm/rev, 0,9
mm and 0,4 mm.
Possible limits of accuracy in measurement of fundamental physical constantsirjes
The measurement uncertainties of Fundamental Physical Constants should take into account all
possible and most influencing factors. One from them is the finiteness of the model that causes the existence of
a-priori error. The proposed formula for calculation of this error provides a comparison of its value with the
actual experimental measurement error that cannot be done an arbitrarily small. According to the suggested
approach, the error of the researched Fundamental Physical Constant, measured in conventional field studies,
will always be higher than the error caused by the finite number of dimensional recorded variables of physicalmathematical
models. Examples of practical application of the considered concept for measurement of fine
structure constant, speed of light and Newtonian constant of gravitation are discussed.
Performance Comparison of Energy Detection Based Spectrum Sensing for Cogniti...irjes
With the rapid deployment of new wireless devices and applications, the last decade has witnessed a growing
demand for wireless radio spectrum. However, the policy of fixed spectrum assignment produces a bottleneck for more
efficient spectrum utilization, such that a great portion of the licensed spectrum is severely under-utilized. So the concept of
cognitive radio was introduced to address this issue.The inefficient usage of the limited spectrum necessitates the
development of dynamic spectrum access techniques, where users who have no spectrum licenses, also known as secondary
users, are allowed to use the temporarily unused licensed spectrum. For this purpose we have to know the presence or
absence of primary users for spectrum usage. So spectrums sensing is one of the major requirements of cognitive radio.Many
spectrum sensing techniques have been developed to sense the presence or absence of a licensed user. This paper evaluates
the performance of the energy detection based spectrum sensing technique in noisy and fading environments.The
performance of the energy detection technique will be evaluated by use of Receiver Operating Characteristics (ROC) curves
over additive white Gaussian noise (AWGN) and fading channels.

length, span 30m and varying bay spacing 4m, 5m and 6m respectively having eaves level for all the portals is at
10m and the EOT crane is supported at the height of 8m from ground level and pre-engineered steel frames of
same dimensions are analyzed and designed for wind zones (wind zone 2, wind zone 3, wind zone 4 and wind
zone 5) by using STAAD Pro V8i. The study deals with the comparative study of both conventional and preengineered
with respect to the amount of structural steel required, reduction in dead load of the structure.
Flip bifurcation and chaos control in discrete-time Prey-predator model irjes
The dynamics of discrete-time prey-predator model are investigated. The result indicates that the
model undergo a flip bifurcation which found by using center manifold theorem and bifurcation theory.
Numerical simulation not only illustrate our results, but also exhibit the complex dynamic behavior, such as the
periodic doubling in period-2, -4 -8, quasi- periodic orbits and chaotic set. Finally, the feedback control method
is used to stabilize chaotic orbits at an unstable interior point.
Energy Awareness and the Role of “Critical Mass” In Smart Citiesirjes
A Smart City could be depicted as a place, logical and physical, in which a crowd of heterogeneous
entities is related in time and space through different types of interactions. Any type of entity, whether it is a
device or a person, clustered in communities, becomes a source of context-based data.
Energy awareness is able to drive the process of bringing our society to limit energy waste and to optimize
usage of available resources, causing a strong environmental and social impact. Then, following social network
analysis methodologies related to the dynamics of complex systems, it is possible to find out, emergent and
sometimes hidden new habits of electricity usage. Through an initial Critical Mass, involving a multitude of
consumers, each related to more contexts, we evaluate the triggering and spreading of a collective attitude. To
this aim, in this paper, we propose a novel analytical model defining a new concept of critical mass, which
includes centrality measures both in a single layer and in a multilayer social network.
A Firefly Algorithm for Optimizing Spur Gear Parameters Under Non-Lubricated ...irjes
Firefly algorithm is one of the emerging evolutionary approaches for complex and non-linear
optimization problems. It is inspired by natural firefly‟s behavior such as movement of fireflies based on
brightness and by overcoming the constraints such as light absorption, obstacles, distance, etc. In this research,
firefly‟s movement had been simulated computationally to identify the best parameters for spur gear pair by
considering the design and manufacturing constraints. The proposed algorithm was tested with the traditional
design parameters and found the results are at par in less computational time by satisfying the constraints.
The Effect of Orientation of Vortex Generators on Aerodynamic Drag Reduction ...irjes
One of the main reasons for the aerodynamic drag in automotive vehicles is the flow separation
near the vehicle’s rear end. To delay this flow separation, vortex generators are used in recent vehicles. The
vortex generators are commonly used in aircrafts to prevent flow separation. Even though vortex generators
themselves create drag, but they also reduce drag by delaying flow separation at downstream. The overall effect
of vortex generators is more beneficial and proved by experimentation. The effect depends on the shape,size and
orientation of vortex generators. Hence optimized shape with proper orientation is essential for getting better
results.This paper presents the effect of vortex generators at different orientation to the flow field and the
mechanism by which these effects takes place.
An Assessment of The Relationship Between The Availability of Financial Resou...irjes
The availability of financial resources is an important element in impacting the success of a planning
process for an effective physical planning. The extent to which however, they are articulated in the process
remained elusive both in scholarly and public discourse. The objective of this study wastherefore, to examine
the extent to which financial resources affect physical planning. In doing so, the study examinedwhether
financial resources were adequate or not to facilitate planning processes in Paidha. According to the study
findings,budget prioritization and ceilings are still a challenge in Paidha Town Council. This is partly due
limited level of knowledge of physical planning among the officials of Paidha Town Council. As a result, there
were no dedicated budget line for routine inspection of physical development plan compliance and enforcement
tools in Paidha. In conclusion, in addressing uncoordinated patterns of physical development that characterize
Uganda‟s urban centres, a critical starting point ought to be the analysis of physical planning process. The
research of this kind is not only significant to other emerging urban centres facing poor a road network,
mushrooming informal settlements and poor social services including poor pattern of residential and commercial
developments but also to all institutions that are involved in planning these towns. Knowing the extent of need
for financial influences in planning may assist local authorities to take the processes of planning seriously which
will help enhance the sustainable development of emerging urban centres including Paidha.
The Choice of Antenatal Care and Delivery Place in Surabaya (Based on Prefere...irjes
- Person's desire to do a pregnancy examination is determined by the service place that suits the tastes
and facilities owned by it. Until now, the utilization of antenatal care by pregnant women is still low (Mardiana,
2014). The purpose of the study is to analyze factors affecting the utilization of antenatal care and delivery place
in Surabaya city based on the preferences and choice theory.
Type of survey research is cross sectional approach, the population is mothers who have children aged 1-
12 months in Surabaya. The large sample of 250 mothers who have children aged 1-12 months in 2013 is taken
by simple random sampling technique. Variables of the research are the preference elements and steps, choice
elements and steps, utilization of antenatal care and delivery place. Data were collected through questionnaires
and secondary data were then analyzed with descriptive statistics in the form of a frequency distribution, shown
by the schematic diagram.
The result showed that the preference elements and steps showed almost half (42.9%) desire to give birth
in a health care because of information got from someone else, while the choice element and step shows the
bulk (57.1%) of the criteria of delivery place chosen is a safe, comfortable and cheap delivery place, the labor
place which is the main choice most (57.1%) is cheap, comfortable, close.
Conclusion of the research based on the preferences and choice theory can be found three (3) new
theories, they are preferences become choice, preferences do not become choice, choice is preceded by
preferences
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Abstract:- Cow manure manure was co-composted with straw in a batch anaerobic composter, to understand
the effects of physical and chemical parameters on composting, for four weeks. Process was performed at
temperature 37o
C. Properties of the material periodically monitored during the composting process were
moisture content, temperature, pH, total nitrogen, total carbon, C/N ration, and total phosphorus and total
potassium were examined at the end of composting. Moisture be maintained in higher level, than 70%. Carbon
to nitrogen ratio of 30 :1 was experimented.

I. INTRODUCTION
Composting is a biological treatment in which aerobic/anaerobic thermophilic and mesophilic
microorganisms use organic matter as a substrate, the main products of this process being fully-mineralized
materials and stabilized organic matter (mostly humic substances). Composting is one of the technologies of
integrated waste management strategies, used for the recycling of organic materials into a useful product. The
application of compost to agricultural land is a practice which is gaining importance particularly due to its
beneficial properties in improving soil fertility and plant growth, and reducing the potential of erosion and
desertification (Gigliotti, Valentini, Erriquens and Said-Pullicino 2005). Composting stabilizes organic wastes
and destroys most parasites, pathogens, and viruses contained in the wastes (Tiquia et al., 2000). However, one
of the most negative effects of composting animal manures is the loss of nitrogen (N) through ammonia (NH3)
volatilization which reduces the fertilizer value of the manure, and constitutes an important economic loss.
Hence, composting changes the nature of the waste and can affect its usefulness as a soil amendment (Tiquia
and Tam, 2000). During composting, carbonaceous and nitrogenous compounds are transformed through the
activities of successive microbial populations into more stable, complex organic forms, which chemically and
biologically resemble humic substances (Bernal, Alburquerque and Moral 2009). The end product obtained from
composting may have some fertilizer value but it should be strongly emphasized that compost is an excellent
soil conditioning agent; reducing the odour emission by decreasing the concentration of volatile compounds
(Smet, Van Langenhove and De Bo, 1999), the moisture content, the potential phytotoxicity and also contributes
to the elimination of pathogens (Tchobanoglous, Kreith and Williams 2002). Measuring physical (temperature,
humidity) and chemical (pH, organic matter content, electric conductivity) parameters to evaluate the progress
of the composting process has become a necessary step to determine the suitability of compost for different uses
(Senesi and Brunetti 1996; Adani et al. 1997; Outmane et al. 2000; Eggen and Vethe 2001). The most widely
used parameter for composting is the C:N ratio of the initial composting material; high initial C:N ratio will
cause a slower beginning of the process and the required composting time to be longer than usual, while low
initial C:N ratio results in high emission of NH3 (Tiquia and Tam, 2000). The pH is one determination employed
to characterize compost and to follow the decomposition process. From the results of batch composting,
reported that pH values near 8 are optimum for composting. The increases in costs of fertilizers and the need for
soil conditioners with some unproductive infertile soils may also stimulate additional interest in composting
(Barberis and Nappi 1996). Many studies on composting organic waste have been conducted to determine the
optimum conditions for composting process. The aim of the present study was to measure the physical and
chemical parameters during composting of preselected organic wastes (dairy manure and bulking agents), in
anaerobic batch. Process was performed at temperature 37o
C. The anaerobic process is very slow, takes
place at low temperature and produces odors. The raw materials, which we used for process, were animal
wastes and straw. Cow manure is commonly applied to farmland directly; hence, it frequently causes
environmental problems (air and water). It will be more valuable if it is converted into an organic fertilizer,
applying composting process to its application on farm land.
II. MATERIAL AND METHOD
This study was conducted using laboratory scale batch composter. The external part of body and the
perforated cover were insulated using cloth to minimize heat loss. The cow manure picked out in farm which

approximately 1 kg was. Bulking agent (absorbent material), such as straw from field was used for composting.
The suitable mixing weight ratio of 2 parts of manure to 1 part bulking agent. Batch composter (Fig. 1) was a
cylinder type (20 x 18 cm) with 1.4 cm thickness glass material. Batch composting unit had a loading capacity
of around 0.5 kg. This laboratory scale composter was built from glass cylinder, which submerged into water
bath. Water temperature was controlled heating equipment, such as temperature controller. Temperature on the
composting process was measured by the continuous self recording thermometer. Temperature measurements
were taken at two locations, 0.10 m from the top and 0.25 from the bottom.

Raw material were composted in seven days and after curing for one month. Storage of produced
compost was ambient temperature in a vinyl chloride envelope without cover. Physical and chemical parameters
of compost were analyzed at an interval of seven days. Solid waste was preliminary treated with drying,
grinding and screening, and then analytically examined. If the sample contains more than 15% moisture, it must
drain to ensure compliance in subsequent analyses. The following chemical and physical properties were
analyzed: a pH, conductivity, moisture, ash and total concentration of N, P, K. The moisture was calculated by
sample weight loss at 105 C for a period of 24 h. The pH and the EC were measured from an aqueous extract.
VS were calculated by sample weight loss at 575 C for 3–4 h. The organic nitrogen was evaluated using the
Kjeldahl method. After components dilution, the solution is analyzed by atomic absorption spectrometer (K) and
by spectrophotometer (P). All values were below the limits established by European Guidelines. The results of
experiments performed for each organic waste, were within the range given for the preparation of compost.
III. RESULTS AND DISCUSSION
The compost process depends on many factors as discussed, especially carbon-to-nitrogen ratios,
moisture content, temperature, pH, EC. The art of composting is balancing these factors to achieve the final
product quality in the desired level. Physical and chemical characteristics of raw materials and analysis for
individual ingredients of it are shown in Table 1.

essential role in the metabolism of microorganisms and indirectly in the supply of oxygen. A moisture content
of 40 to 60 percent provides adequate moisture. If moisture content falls below 40 percent, bacterial activity will
slow down, and will cease entirely below 15 percent. When the moisture content exceeds 60 percent, nutrients
are leached, air volume is reduced, odours are produced (due to anaerobic conditions), and decomposition is
slowed. Adding dry material, such as straw can also remedy an excess moisture problem. If the materials are too
wet, anaerobic conditions will dominate the composting process. In our case, the moisture content of the
compost mass in anaerobic batch, remained 75 - 80% (w. B).

Determination of organic matter is a more routinely procedure for composts and provides an estimate of all
substances containing organic carbon. The organic matter results obtained from batch composter are shown in
figure 3. The experiment results showed a decrease in organic matter, but the composters should stay much
more longer than twenty one days, to achive an optimal results, until organic matter result under 70%.
Fig. 3 Organic matter (%) results during composting process
The pH level of the composting mass typically varies with the passage of time. The initial pH of
mixture during the composting process, was 7.67. The pH of the produced compost remained consistently close
to 7 or 8 independent of the variations in pH for the initial mixtures. The studies carried out have shown that pH
values near 8 are optimum for composting. pH values of straw was alkaline, hence compost mixture should be
valuable as acid soil conditioner. pH values during composting process are presented in figure 4. In initial phase
pH values reduced, due to increased amount of organic acids. Stabilization of pH values were done in the
coming days.

Fig. 4 pH of composting organic waste
Electrical conductivity affects the quality of compost because it reflects the suitability salinitetin and
plant growth. This parameter is increased for some samples after the active phase, probably due to the release of
soluble salts such as ammonia and phosphates, resulting from the decomposition of biodegradable organic
subtrateve. Electrical conductivity results show that mixtures are within the allowable rate, and can be used for a
wide range of plants (figure 5).
Fig. 5 EC of composting organic waste
Carbon and nitrogen compounds are important components in composting process, excessive or
insufficient amounts depends in material. Microorganisms in compost digest (oxidize) carbon as an energy
source, and ingest nitrogen for protein synthesis. The proportion of these two elements should approximate 30
parts carbon to 1 part nitrogen by weight. C:N ratios within the range of 25:1 to 40:1 result in an efficient
process. Straw is good sources of carbon. Cow manure is a good source of nitrogen. The mixed straw compost
contained 1.5 to 3.2 percent nitrogen. The initial C/N ratio of raw material was 15 for caw manure and 122 for
straw, and also produced compost of it was 21 – 31. This may have been due to vigorous NH3 volatilization
during composting. At the initial C/N ratio was to high, for this reason composting was delayed. Reduction in
C/N ratio of composting material is presented in Figure 6.

IV. CONCLUSIONS
Dairy manure is one of organic amendments that can improve the physical, chemical and biological
characteristics of the soils This study was initiated to investigated the effect of initial condition about
moisture content, pH value, C/N ratio, during the anaerobic composting process , mixed dairy manure
with bulking agents. Degree of composting should be affected by physical factors. Dairy manure can be
composted in a batch composter in around four weeks. Mixing weight ratio was of dairy manure to
bulking agent successfully composted was 2 parts of manure to 1 part bulking agent. Favorable moisture
content of initial condition was ranged from 60-65 % (w. b.), during the process was maintained 70-85%.
It could not be composted satisfactory due to the initial low pH value. The pH of the produced compost
remained consistently close to 7 or 8 independent of the variations in pH for the initial mixtures. The influence
of the nitrogen component on the decomposition was very important. The carbon-to-nitrogen ratio (C:N)
is a major nutrient factor. Adequate levels of phosphorus and potassium are also important in the composting
process and are normally present in farm organic material such as manure. Concentration of macro and micro
nutrients such a nitrogen, phosphorus and potassium in finished compost was higher than that of initial compost.
Initial phosphorus content was 0.173, and in the end was 0.201; and potassium content 1.13 to 1.41.
