Information about the variability of chlorophyll-a and sea surface temperature is a reference to determine the potential fishing area (fishing ground). This study aims to determine the variation of chlorophyll-a and sea surface temperature effects on Cakalang (Katsuwonus Pelamis) fish catches in the waters of Sawu sea, East Nusa Tenggara. Predictions of potential areas of skipjack capture are determined based on statistical analysis and multitemporal analysis. The results showed that variations in chlorophyll-a and sea surface temperature were very influential with the catches of Cakalang in the waters of Sawu. Chlorophyll-a increases in the East season (June-August) and at the beginning of Transition II (September), so this season has the potential to catch Cakalang fish.
This study aims to analyze the influence of physical and chemical factors on the
existence of Kurau Fish (Eleutheronema tetradactylum) in the Maro River Estuary of
Merauke Regency. Data collection was carried out by measuring the environmental
parameters directly, namely temperature, salinity and pH, while the fish catch data of
Kurau was obtained by calculating directly the number of catches per trip with the data
amount of 34 data. Environmental factor data and catch results were tested statistically
using regression models. The results showed that environmental factors that influence
the presence of Kurau Fish in the Maro River Estuary are water temperature and
salinity.

The research aims to know the condition of environmental parameters both from biological factors and physical factors of the Makassar Strait during the East season. The usability of the research ie can be to build and simulate dynamic models of fisheries systems. Data Collection has been carried since May 2019 to November 2019. Data collection on environmental parameters (temperature, salinity, pH, dissolved oxygen, flow velocity) and nutrients (nitrates and phosphates), phytoplankton and zooplankton abundance, , and gastric contents analysis were carried out, Method for analysing was used analysis of variance (ANOVA) to compare environmental parameters, nutrients and abundance of plankton between the three districts observed. The relationship between the abundance of plankton with environmental parameters was analyzed by using multiple linear regression analysis. Determination of trophic level is based on analysis of gastric contents using the TrophLab 2K program. Results of analysis of variance (ANOVA) between observation stations grouped in 6 months of observation showed that salinity was significantly different between locations and months of observation, temperature and pH were significantly different between months but did not differ according to location of observation, whereas DO levels did not show differences either between locations. The results of identification of phytoplankton types obtained during this research were dominated by diatoms. The type of zooplankton obtained is generally dominated by copepods. The result of gastric surgery is 10 dominant and economically valuable fish's species belonging to planktivor, omnivor and carnivor fish, and based on ecosystems including pelagic and demersal fish.

Pulau Sulawesi merupakan salah satu pulau terbesar di Indonesia dan dikenal memiliki potensi di bidang kelautan, baik dari segi pariwisata hingga potensi perikanannya. Pulau ini dilintasi garis khatuliswa di seperempat bagian utara sehingga sebagian besar wilayahnya berada di belahan bumi selatan. Geografis pulau Sulawesi yang berbeda menyebabkan perbedaan karakteristik parameter oseanografi. Salinitas dan pasang surut air laut merupakan parameter oseanografi yang dapat mempengaruhi keberlangsungan hidup biota di suatu perairan. Tujuan dari penelitian ini adalah melakukan studi parameter oseanografi fisika kimia yang meliputi pasang surut dan salinitas di perairan pulau Sulawesi menggunakan data NOAA dan BIG. Dari penelitian yang telah dilakukan menunjukkan bahwa perairan di sekitar Pulau Sulawesi memiliki rerata muka air tinggi sebesar 1,3 meter dan muka air rendah sebesar 0,9 meter. Kemudian dari perhitungan dihasilkan bilangan Formzahl sebesar 0,8 (0,25 < F £ 1,5) yang berarti tipe pasang surut masuk dalam kategori Campuran, cenderung Semi Diurnal. Kemudian hasil analisis salinitas menunjukkan bahwa pada bulan Juli tahun 2020 kandungan salinitas berkisar 29,63 hingga 36,45 ppt dengan rata-rata 33,99 ppt. Pada bulan November 2020 kandungan salinitas berkisar 25,71 hingga 39,74 ppt dengan rata-rata sebesar 33,50 ppt.

Pada musim kemarau rata-rata kandungan salinitas air laut di perairan Sulawesi relatif tinggi dibandingkan musim penghujan dengan nilai kandungan terendah sebesar 29,63 ppt.
Climate change and its impact on the fisheries in Lake Kivu, East AfricaInnspub Net
Climate change, its variability, and its impact on fish catch in Lake Kivu were verified from the analysis of climate variables and fisheries statistics. The results show qualitative and quantitative disturbances in the variation of rainfall, the significant increase in temperature of 1.57°C, 0.63°C, and 0.66°C at Kamembe, Gisenyi, and Lwiro, respectively around Lake Kivu watershed. The relative humidity decreased significantly by 4.5% and 7% at Gisenyi and Kamembe, respectively; the wind speed decreased by 3 m/s. These changes resulted in a decrease of 0.58 m in the water level of the lake, followed by periods of declines in catches of Limnothrissa modern, the major lake’s commercial fish. Predictions show a decline in Catch per Unit Effort of 2.92 kg for an approximate reduction
of 0.01 m water level by 2025. Strategic policies should be made and adaptation measures are taken to prevent climate change, in order to conserve the aquatic resources and avoid advert conditions in the fisheries sector of Lake Kivu.
Investigation of the Tidal Character in Bawean Island East Java Using Admiral...Luhur Moekti Prayogo
Bawean Island is one of the islands in Gresik Regency, East Java, where almost all its territory is a coastal environment. This region's tidal oceanographic condition is critical because this area has a lot of potential for marine tourism and relatively shallow waters. This study aims to determine the tidal characteristics in the waters of Bawean Island, East Java, using the Admiralty method. This method was chosen because it can calculate the tidal component with only 15 days of data and can be used in various water conditions. The data used is tidal data from the Geospatial Information Agency (BIG) on November 1-15, 2020. From this research, it can be concluded that tidal analysis using the Admiralty method produces nine components, including M2, S2, N2, K1, O1, P1, M4, MS4, and K2. The four components determine the type of tide, namely O1, K1, M2, and S2, with amplitude values of 11.79347, 30.14857, 55.72241, and 63.69851. The calculation with the Formzahl number equation yields a value of 0.3512 (0.25 <F <1.5), which means that the tidal type in Bawean Island, East Java, has a mixed type with a semidiurnal tendency (double daily).

Abrupt change is a hallmark of the climate record. It has happened in the past, and is already happening in some systems now.
Abrupt climate change—large shifts in climate that take place within decades or even years—is the topic of increasing scientific research because of the potential for such changes to happen faster than society or ecosystems could adapt. A new report from the National Research Council evaluates the potential for abrupt changes in the ocean, atmosphere, ecosystems, and high latitude regions to help decision makers and communities make informed decisions about how to prepare for sudden changes. The report calls for an early warning system to help society better anticipate abrupt changes.

Nepal does not have own climate projection model. Therefore, climate change studies in Nepal completely depend on the results of available model throughout the world. Many field based studies have proven that Nepal is the most vulnerable country in the context of climate change due to limited capacity to adapt to it. On the other hand, it is a big challenge to natural scientists to demonstrate climate change physically because of limited resources. Due to the complex geography of Nepal, most of the global climate projections are not able to capture the temporal and spatial climatic variability. In consideration to this problem, the Department of Hydrology and Meteorology (DHM) of Nepal has initiated a project to downscale climatic parameters regionally with technical support from the Asian Disaster Preparedness Centre (ADPC) under the financial support of Asian Development Bank (ADB). They used three different Regional Climate Models (RCM); PRECIS, RegCM4, and WRF under AR4 scenarios. However, there is still a lot of discrepancy among these projections which have created confusion among the stakeholders. Therefore, the objective of my presentation will be to focus on the discussion over these issues among the climate experts at UNBC.
This research was done in Pelabuhan Ratu Bay, about 60 km South Sukabumi Regency. The aim of this study is to determine the suitable area for floating net cage culture that can be developed.

PRODUCTIVITY VARIATION OF SOUTHEASTERN ARABIAN SEA: INFERENCES FROM BENTHIC F...IAEME Publication
The Indian monsoon has a strong impact on the climate of the southern Arabian Sea (SEAS). To analyze paleoenvironmental and paleoclimatic changes during the last 13.5 kyr BP, we created proxy records of benthic foraminiferal diversity in sediments from core SK215/GC05 in the continental shelf off Cochin, off the (SEAS). We found 21 species in 10 sediment subsamples from this investigation. Among them are four species: a) Uvigeriperigrina, Sp., b). Cibicidesrobertsiniaus, Sp., c). Sp. Anomalinella rostrate, and d). Palaeoclimatic indicators, such as Ammomassilinaalveoloformis Sp., are employed. The findings indicate a positive relationship between the four dominant species in the SEAS. We determined that the late glacial to early Holocene periods (13.5 to 9 kyr BP) were less productive, and the Holocene climatic optimum (9 to 5 kyr BP) had the highest production, following which productivity stabilized (5 to 1 kyr BP). Our findings are consistent with the global climatic trend in the northern hemisphere.
GIS based spatial distribution of Temperature and Chlorophyll-a along Kalpakk...IJERA Editor
This paper briefly describes the status of Temperature and Chlorophyll-a trend in Kalpakkam Coast, discusses its ecological and temperature impacts recommending measures to achieve long term sustainability using advanced tools like Geographic Information System (GIS). Present study reveals the monthly spatial distribution of Temperature and Chlorophyll-a at Kalpakkam. Transect based in-situ Temperature and Chlorophyll-a collected at 200m, 500m and 1 km distance into the sea was interpolated using the Inverse Distance Weightage (IDW) method in ARC GIS. Data revealed the extent of spatial distribution of thermal effluent in Kalpakkam. It could be found that temperature range of 26.2 – 31.9°C provided substantial Chlorophyll-a concentration between 0.8 – 2.9 mg/m3 for surface and bottom waters. Further, increase of Chlorophyll-a levels did not lead to higher productivity. Combined temperature and chlorophyll a showed little synergistic effects. It is concluded that the effect of thermal discharge from the power plant into the receiving water body is quite localized and productivity of the coastal waters are not affected. From the results obtained, the spatial data has been found to be useful in determining zones of safe use of seawater and to understand the extent of relationship between the relatable parameters.
Fluctuation of NO3-N and PO4 Elements in The Traditional Pond Area at TidesIJAEMSJORNAL
Traditional pond technology depends on nature in management, such as filling and disposal of pond water utilizing the time of low and high tides. The food for traditional pond technology comes from nature. The availability of nutrients such as N and P greatly determines the productivity of pond. The study was aimed to determine the fluctuations of N and P elements in traditional pond areas at tides. This research was conducted with purposive sampling method and laboratory analysis for several water parameters. The results showed that pH ranged from 7 to 8 both at low tide and high tide.

Diversity of fish and macrobenthos at the coastal area of Tanjung Kidurong Po...AbdullaAlAsif1
The regular assessment of faunal diversity near the energy power plant has gained the interest of many researchers. The activity and the effluent discharged from the power plant have remarkably stressed the adjacent assemblage of the alpha biotic community surrounding the power plant. Hence, this study aimed to assess the alpha faunal diversity of fishes and benthos in the bordering areas of Tanjung Kidurong Combined Cycle Power Plant (TKCCP), Bintulu Sarawak. The investigation was conducted in the coastal area from 2019 to 2020. Different ecological indices such as the evenness index, Margalef richness, and Shannon-Weiner diversity index were implemented, along with the cluster analysis of other stations. A number of 141 fish individuals were recorded, containing 40 species of 19 families. In addition, 13182 individuals of benthos communities from six classes and 37 species were identified. A percentage of 78 comprised fishes, while 22% were identified as crustaceans. Among the benthos addressed, Foraminifera was the major group (74%), followed by bivalve (10%) and Scaphopoda (7%). Compared to SEB2, 3 & 4, SEB1, the nearest to the power plant, recorded the highest richness, number of species, and diversity indexes. Cluster analysis, PCA, and nMDS analysis suggested that SEB2, SEB3, SEB4 had similar biodiversity compositions. The study of benthos indicates that SEB1 possesses a distinguished value of diversity and evenness indexes. This study would provide future researchers with vital documentation to evaluate the impact of thermal discharge from the power plant on alpha biodiversity in Bintulu, Sarawak, Malaysia.
Sea level rise impact modelling on small islands: case study gili raja island...Luhur Moekti Prayogo
Coastal regions and small islands are areas that will be adversely affected by the phenomenon of sea level rise globally. In general, Sea Level Rise (SLR) will result in coastal impacts as follows: increased frequency and intensity of floods, changes in ocean currents and widespread intrusion of sea water. This research was conducted in Gili Raja Island of Sumenep Madura. Objectives of this research were to demonstrate the ability of combining remote sensing and GIS method to determine the impact of SLR on a small island and to model its scale using different scenario. GIS based run-up model were performed to estimate and predict the impact of SLR to the island’s area. Three water level scenario (0.5 m, 1.0 m and 1.5 m) were applied. The results showed that in the first scenario 8.73% of the island was flooded by sea water, furthermore in two other scenario the flooded area was increase significantly (15.88% and 22.38%).

Integrating fuzzy logic and genetic algorithm for upwelling prediction in Man...TELKOMNIKA JOURNAL
Upwelling is a natural phenomenon related with the increase in water mass that also occurs in Maninjau Lake, West Sumatra. The upwelling phenomenon resulted in considerable losses for freshwater fish farming because make mass mortalities of fish in farming using the method of floating net cages (karamba jaring apung/KJA). It takes a system that can predict the possibility of upwelling as an early warning to the community, especially fish farming to immediately prepare early anticipation of upwelling prevention. With historical water quality monitoring data at six sites in Maninjau Lake for 17 years, a prediction model can be made. There are three input criteria for Tsukamoto FIS that is water temperature, pH, and dissolve oxygen (DO). The model is built with fuzzy logic integration with the genetic algorithm to optimize the membership function boundaries of input and output criteria. After the optimization, hybrid Tsukamoto FIS and genetic algorithm successfully make a correct upwelling prediction on of 16 data with 94% accuracy.

Interface change of seawater and freshwater on Asam – Asam Watersheds, South ...Innspub Net
Temporal change of seawater and fresh water interface in the watershed area needs scientific study on dynamics of ecosystem parameters in different seasons and analysis of satellite imagery. This research aims to assess the change of interface seawater and freshwater from the temporal estuary upstream. The study used four methods: (1) Interviews with local community respondents; determined with snowball method. (2) Secondary data obtained from the Report of Environmental Monitoring Result of Power Plant Operations of Asam – Asam in 2014 (3) Observed parameters include pH, salinity, electrical conductivity in the dry season (August), transition (October) and rainy season (December). (4) Temporal observations with the use of satellite imagery analysis with Nipah (Nypa fruticans Wurmb) as indicator. According to the respondent, seawater intrusion has occurred extremely from the estuary of Asam-Asam river to the upstream. Secondary data shows significant differences in the intake value of DHL Asam-Asam power plant (546 μ mhos/cm) with upstream intake (231 μ mhos/cm) which means the intrusion of sea water is moderate to high level. Field observations show the dry season (August 2013) interface was 12.86 miles from the estuary, whereas in transitional season (October 2013) was 12.53 miles from estuary, and rainy season (December 2013) is 5.24 km from the estuary. Satellite imagery showed the interface in 1991 was 8.13 miles from the estuary and increase upstream from 0.03 to 1.86 per year. In 2014, the interface becomes 12.88 miles from the estuary. This shows that the sea water increasingly moving toward the river. Get more articles at: http://www.innspub.net/volume-6-number-4-april-2015-jbes/

Sathean Bay is a small, semi-enclosed waters which have been utilized as an area for pearl oyster farming using floating long line method. The growth of pearl oysters are affected by the availability of food (phytoplankton) in the waters. The phytoplankton own self is highly affected by N and P in the waters. This study aims to assess the carrying capacity of the Sathean Bay for pearl oysters farming for three different size group pearl oyster based on the nutrient balance which was the ratio between N and P are available in the waters and in the pearl oyster tissue. The study was conducted from April to September 2016 in nine sampling sites of Sathean Bay, Southeast Maluku. The result showed the smallest group size of pearl oyster(5 ± 2 cm) had the highest carrying capacity among the other two size group (13 ± 2 cm, 18 ± 2 cm). The carrying capacity of pearl oyster based nitrogen level(DIN) in the waters was always greater than the carrying capacity based on DIP level for all size groups of pearl oyster.
Greetings all,
This month’s newsletter is devoted to ocean indices aiming at a better understanding of the state of the ocean climate. Ocean
climate indices can be linked to major patterns of climate variability and usually have a significant social impact. The estimation of
the ocean climate indices along with their uncertainty is thus crucial: It gives an indication of our ability to measure the ocean. It is
as well a useful tool for decision making. Ocean climate indices also provide an at-a-glance overview of the state of the ocean
climate, and a way to talk to a wider audience about the ocean observing system. Several groups of experts are now working on
various ocean indicators using ocean forecast models, satellite data and reanalysis models in observing system simulation
experiments, among which the OOPC, NOAA and MERSEA/Boss4Gmes communities for example:

http://www.mersea.eu.org/Indicators-with-B4G.html
Scientific articles about Ocean indices in the present Newsletter are displayed as follows: The first article by Von Schuckmann et
al. is dealing with the estimation of global ocean indicators from a gridded hydrographic field. Then, Crosnier et al. are describing
the need to conduct intercomparison of model analyses and forecast in order for experts to provide a reliable scientific expertise
on ocean climate indicators. The next article by Coppini et al. is telling us about ocean indices computed from the Mediterranean
Forecasting System for the European Environment Agency and Boss4Gmes. Then Buarque et al. are revisiting the Tropical
Cyclone Heat Potential Index in order to better represent the ocean heat content that interacts with Hurricane. The last article by Greiner et al. is dealing with the assessment of robust ocean indicators and gives an example with oceanic predictors for the
Sahel precipitations.
The next July 2009 newsletter will review the current work on data assimilation and its techniques and progress for operational
oceanography.
We wish you a pleasant reading.

Living in 21st century in itself reminds all of us the necessity of police and its administration. As more and more we are entering into the modern society and culture, the more we require the services of the so called ‘Khaki Worthy’ men i.e., the police personnel. Whether we talk of Indian police or the other nation’s police, they all have the same recognition as they have in India. But as already mentioned, their services and requirements are different after the like 26th November, 2008 incidents, where they without saving their own lives has sacrificed themselves without any hitch and without caring about their respective family members and wards. In other words, they are like our heroes and mentors who can guide us from the darkness of fear, militancy, corruption and other dark sides of life and so on. Now the question arises, if Gandhi would have been alive today, what would have been his reaction/opinion to the police and its functioning? Would he have some thing different in his mind now what he had been in his mind before the partition or would he be going to start some Satyagraha in the form of some improvement in the functioning of the police administration? Really these questions or rather night mares can come to any one’s mind, when there is too much confusion is prevailing in our minds, when there is too much corruption in the society and when the polices working is also in the questioning because of one or the other case throughout the India. It is matter of great concern that we have to thing over our administration and our practical approach because the police personals are also like us, they are part and parcel of our society and among one of us, so why we all are pin pointing towards them.

Globally, Millions of dollars were spent by the organizations for employing skilled Information Technology (IT) professionals. It is costly to replace unskilled employees with IT professionals possessing technical skills and competencies that aid in interconnecting the business processes. The organization’s employment tactics were forced to alter by globalization along with technological innovations as they consistently diminish to remain lean, outsource to concentrate on core competencies along with restructuring/reallocate personnel to gather efficiency. As other jobs, organizations or professions have become reasonably more appropriate in a shifting employment landscape, the above alterations trigger both involuntary as well as voluntary turnover. The employee view on jobs is also afflicted by the COVID-19 pandemic along with the employee-driven labour market. So, having effective strategies is necessary to tackle the withdrawal rate of employees. By associating Emotional Intelligence (EI) along with Talent Management (TM) in the IT industry, the rise in attrition rate was analyzed in this study. Only 303 respondents were collected out of 350 participants to whom questionnaires were distributed. From the employees of IT organizations located in Bangalore (India), the data were congregated. A simple random sampling methodology was employed to congregate data as of the respondents. Generating the hypothesis along with testing is eventuated. The effect of EI and TM along with regression analysis between TM and EI was analyzed.

A STUDY OF VARIOUS TYPES OF LOANS OF SELECTED PUBLIC AND PRIVATE SECTOR BANKS...IAEME Publication
Banking regulations act of India, 1949 defines banking as “acceptance of deposits for the purpose of lending or investment from the public, repayment on demand or otherwise and withdrawable through cheques, drafts order or otherwise”, the major participants of the Indian financial system are commercial banks, the financial institution encompassing term lending institutions. Investments institutions, specialized financial institution and the state level development banks, non banking financial companies (NBFC) and other market intermediaries such has the stock brokers and money lenders are among the oldest of the certain variants of NBFC and the oldest market participants. The asset quality of banks is one of the most important indicators of their financial health. The Indian banking sector has been facing severe problems of increasing Non- Performing Assets (NPAs). The NPAs growth directly and indirectly affects the quality of assets and profitability of banks. It also shows the efficiency of banks credit risk management and the recovery effectiveness. NPA do not generate any income, whereas, the bank is required to make provisions for such as assets that why is a double edge weapon. This paper outlines the concept of quality of bank loans of different types like Housing, Agriculture and MSME loans in state Haryana of selected public and private sector banks. This study is highlighting problems associated with the role of commercial bank in financing Small and Medium Scale Enterprises (SME). The overall objective of the research was to assess the effect of the financing provisions existing for the setting up and operations of MSMEs in the country and to generate recommendations for more robust financing mechanisms for successful operation of the MSMEs, in turn understanding the impact of MSME loans on financial institutions due to NPA. There are many research conducted on the topic of Non- Performing Assets (NPA) Management, concerning particular bank, comparative study of public and private banks etc. In this paper the researcher is considering the aggregate data of selected public sector and private sector banks and attempts to compare the NPA of Housing, Agriculture and MSME loans in state Haryana of public and private sector banks. The tools used in the study are average and Anova test and variance. The findings reveal that NPA is common problem for both public and private sector banks and is associated with all types of loans either that is housing loans, agriculture loans and loans to SMES. NPAs of both public and private sector banks show the increasing trend. In 2010-11 GNPA of public and private sector were at same level it was 2% but after 2010-11 it increased in many fold and at present there is GNPA in some more than 15%. It shows the dark area of Indian banking sector.

ROLE OF SOCIAL ENTREPRENEURSHIP IN RURAL DEVELOPMENT OF INDIA - PROBLEMS AND ...IAEME Publication
The majority of the population in India lives in villages. The village is the back bone of the country. Village or rural industries play an important role in the national economy, particularly in the rural development. Developing the rural economy is one of the key indicators towards a country’s success. Whether it be the need to look after the welfare of the farmers or invest in rural infrastructure, Governments have to ensure that rural development isn’t compromised. The economic development of our country largely depends on the progress of rural areas and the standard of living of rural masses. Village or rural industries play an important role in the national economy, particularly in the rural development. Rural entrepreneurship is based on stimulating local entrepreneurial talent and the subsequent growth of indigenous enterprises. It recognizes opportunity in the rural areas and accelerates a unique blend of resources either inside or outside of agriculture. Rural entrepreneurship brings an economic value to the rural sector by creating new methods of production, new markets, new products and generate employment opportunities thereby ensuring continuous rural development. Social Entrepreneurship has the direct and primary objective of serving the society along with the earning profits. So, social entrepreneurship is different from the economic entrepreneurship as its basic objective is not to earn profits but for providing innovative solutions to meet the society needs which are not taken care by majority of the entrepreneurs as they are in the business for profit making as a sole objective. So, the Social Entrepreneurs have the huge growth potential particularly in the developing countries like India where we have huge societal disparities in terms of the financial positions of the population. Still 22 percent of the Indian population is below the poverty line and also there is disparity among the rural & urban population in terms of families living under BPL. 25.7 percent of the rural population & 13.7 percent of the urban population is under BPL which clearly shows the disparity of the poor people in the rural and urban areas. The need to develop social entrepreneurship in agriculture is dictated by a large number of social problems. Such problems include low living standards, unemployment, and social tension. The reasons that led to the emergence of the practice of social entrepreneurship are the above factors. The research problem lays upon disclosing the importance of role of social entrepreneurship in rural development of India. The paper the tendencies of social entrepreneurship in India, to present successful examples of such business for providing recommendations how to improve situation in rural areas in terms of social entrepreneurship development. Indian government has made some steps towards development of social enterprises, social entrepreneurship, and social in- novation, but a lot remains to be improved.
OPTIMAL RECONFIGURATION OF POWER DISTRIBUTION RADIAL NETWORK USING HYBRID MET...IAEME Publication
Distribution system is a critical link between the electric power distributor and the consumers. Most of the distribution networks commonly used by the electric utility is the radial distribution network. However in this type of network, it has technical issues such as enormous power losses which affect the quality of the supply. Nowadays, the introduction of Distributed Generation (DG) units in the system help improve and support the voltage profile of the network as well as the performance of the system components through power loss mitigation. In this study network reconfiguration was done using two meta-heuristic algorithms Particle Swarm Optimization and Gravitational Search Algorithm (PSO-GSA) to enhance power quality and voltage profile in the system when simultaneously applied with the DG units. Backward/Forward Sweep Method was used in the load flow analysis and simulated using the MATLAB program. Five cases were considered in the Reconfiguration based on the contribution of DG units. The proposed method was tested using IEEE 33 bus system. Based on the results, there was a voltage profile improvement in the system from 0.9038 p.u. to 0.9594 p.u.. The integration of DG in the network also reduced power losses from 210.98 kW to 69.3963 kW. Simulated results are drawn to show the performance of each case.

2. Variability of Chlorofil-a and Sea Surface Temperature, the Effect on the Catches of Cakalang
Fish in Sawu Sea of East Nusa Tenggara
http://www.iaeme.com/IJCIET/index.asp 716 editor@iaeme.com
fish in the Savu Sea is 156,000 tons / year (KEPMEN-KP Number 6 of 2014). This shows that
the potential of fish in the waters needs to be utilized optimally by operating fishing gear
effectively and efficiently.
According to Syamsuddin et al. (2008), the level of exploitation of fish resources in Kupang
has not reached optimal conditions. In this connection, efforts need to be made in the form of
adding fishing operations, fishing gear units and searching for new fishing areas by utilizing
fish detection devices (echosounder and remote sensing).
Fishing operations by East Nusa Tenggara fishermen are generally still dependent on
information from fellow fishermen and their own experience by utilizing the five senses to
predict fishing grounds. While the availability of fish resources in a waters region always
changes along with changes in the environment.
In addition to optimizing the use of fishing gear in fishing activities, information on
environmental conditions is also needed in the form of oceanographic parameters.
Oceanographic parameters include chlorophyll-a and sea surface temperature (SPL). By
knowing the environmental conditions, especially chlorophyll-a and optimum sea surface
temperature of a fish species in a waters, of course it will facilitate fishermen in predicting
potential fishing areas. Sea surface temperature is closely related to the suitability of
physiological conditions and morphological adaptation of fish. Besides that sea surface
temperature becomes an indirect indicator of biological productivity or the presence of fish
food (Santos, 2000). Whereas chlorophyll-a is a factor that can provide a direct indication of
the existence of fish food and the pathways of fish migration areas (Polovina et al., 2011).
Some results of research conducted in Indonesian waters indicate that oceanographic
parameters such as temperature, salinity, chlorophyll-a concentration, upwelling, eddies are
related to fish existence (Mukhlis et al., 2009; Mugo, 2010; Zainuddin et al., 2015) . According
to Gaol (2010) it is more assertive that information about oceanographic parameters and
dynamics is an absolute necessity for forecasting potential fishing areas.
One alternative that can be used to obtain environmental conditions in the form of
oceanographic parameters is to utilize GIS capabilities and marine sensing. Ocean senses are
able to provide data on the scale of globa on the surface layer of the water. Data from the results
of oceanographic satellite shooting can be used to monitor various marine phenomena such as
upwelling, eddy, fronts and altimetry which are closely related to fisheries activities (Kotta et
al., 2018; Padmaningrat et al., 2017). One sensory satellite equipped with a sensor that can
detect chlorophyll-a and SPL content is the Aqua Moderate Resolution Imaging
spectroradiomete (Aqua MODIS) satellite.
Based on the description above, it is necessary to do research on the variability of
chlorophyll-a and sea surface temperature spatially and temporally as a basis for determining
fishing areas in the waters of Sawu sea. The purpose of this study is to determine the variability
of chlorophyll-a and sea surface temperature and the factors that influence it.

Regression analysis is used to determine the effect of independent variables with dependent
variables. According to Padmaningrat et al. (2017) regression analysis method can be used to
see linear regression and correlation analysis to find out how much the relationship between
oceanographic parameters (sea surface temperature and chlorophyll-a) to the number of fish
catches. Regression analysis according to Bender et al. (2014) can be expressed in equation 1,
i.e.:
Y = a0 + a1x + a2x2

Y = CPUE the results of the capture of Cakalang
a = constant
X = Oceanographic parameters (chlorophyll-a and sea surface temperature).
A perfect linear relationship occurs between x and y if the value r = +1 or -1. If the value
of r approaches this value, there is a high correlation between the two variables, whereas if the
value of r approaches zero, the linear relationship between the values of x and y is very weak.
Correlation analysis aims to measure the strength or closeness of the relationship between two
variables (Bender et al., 2014). According to Bender et al. (2014) correlation analysis can be
expressed in equation 2, i.e.:
(2)
Where:
= correlation coefficient value
= amount of catch data
= the amount of Cakalang's catch
= Oceanographic parameters (sea surface temperature and chlorophyll-a)
According to De Vaus (2001), to interpret the results of correlation studies are presented in

3. RESULTS
Catching Cakalang fish in the waters of the Savu sea is one day fishing. Cakalang fishing
activities in Sawu sea waters during the period of January - December 2017 are divided into 4
seasons namely the West season, Transition I season, East season and Transition II season.
Based on data from look book pole and line capture of Cakalang fish obtained by catch data
during the period January - December 2017 as many as 193 fishing trips with a total production
of 579,217 kg, of which in the West season as many as 11 trips with catches reached 22,028
kg, in the Transition I season 53 trip with the catch of 127,038 kg, the East season 14 trips with
the catch of 70,225 kg and the transition season II as many as 114 trips with the results of
359,926 kg. Cakalang fish production during the period of January - December 2017 can be
seen in Figure 2.

3.1. RELATIONSHIP BETWEEN CHLOROPHYLL-A PARAMETERS AND SEA
SURFACE TEMPERATURE AGAINST CAKALANG CATCHES
The relationship of the chlorophyll-a pathameter and sea surface temperature to Cakalang's
monthly CPUE can be seen in Figure 3.
Figure 3. Graph of relationship between Chlorophyll-a and sea surface temperature to Cakalang
monthly CPUE
Figure 3 shows CPUE tends to start increasing in June and peaked in August and then began
to decline again in September. This indicates that the increase in chlorophyll-a and cooling of
sea surface temperature has a very strong relationship to the CPUE of Cakalang catches in the
waters of Sawu sea, in August the sea surface temperature cooled to reach a low value of 27
oC causing an increase in chlorophyll-a concentration reaching 0.5 mg / m3 and followed by a
high CPUE catch of 6,330 kg. Zainuddin et al. (2013) High CPUE of skipjack fish from April
to June to the east following a periodic increase in chlorophyll-a concentration in the eastern
part of Bone Bay. It is strongly suspected that the food of skipjack fish increases along with

the development of concentrations of chlorophyll-a and is then followed by a high cluster of
gathered tuna. Thus a potential zone of catching skipjack fish will be created.
The relationship between chlorophyll-a parameters and sea surface temperature on
Cakalang catches was analyzed using multiple regression with catch as dependent variable,
chlorophyll-a and SPL as independent variables.
Analysis of variance (Test F) was used to see the relationship of chlorophyll-a and sea
surface temperature together to the catches of Cakalang fish, the results of the analysis can be
seen in table 1 (b). Table 1 (b) shows that the significant value obtained is 0,000 less than (0.05)
with Fcount = 57,789 (> Ftable = 3.12), this shows together that chlorophyll-a and sea surface
temperature have a significant effect on Cakalang catches.

Correlation coefficient value is used to determine the magnitude of the influence of
independent variables on the dependent variable, table 1 (a) shows the correlation coefficient
(R) of 0.783, this means that the relationship between chlorophyll-a and sea surface
temperature to Cakalang fish catches is 78%. The detrmination coefficient (R2) is 0.613,
meaning that 63% of the effect of the catch is influenced by chlorophyll-a and sea surface
temperature while 37% is influenced by other factors.
The results of the analysis using regression analysis can be used to see the magnitude of
the influence of chlorophyll-a and sea surface temperature on Cakalang catches, in the analysis
all data from chlorophyll-a converts, sea and fish surface temperatures, data generated in
converts to 80 data for chlorophyll-a and 125 data for sea surface temperature. The results of
the regression analysis showed a relationship between chlorophyll-a and Cakalang catch
(Figure 4), with a coefficient of determination (R2) 0.686, which means that 68% of the catches
of Cakalang are affected by chlorphyl-a. The trendline line (Figure 4) shows an increase in
chlorophyll-a concentration followed by an increase in the number of catches of Cakalang,
catches of Cakalang in Sawu sea water increase when the chlorophyll-a condition reaches 0.92
mg / m3 and decreases in chlorofi-a 0.16 mg / m3.

Figure 4. Relationship of chlorophyll-a to catch
The relationship of sea surface temperature to Cakalang catches can be seen in (Figure 5),
with a coefficient of 0.486 which means that the effect given by sea surface temperature on
Cakalang catches is 48% smaller than chlorophyll-a. Sriawan (2002) explains that sea surface
temperature does not have too much influence on the catches of Cakalang in the waters of the
Savu Sea. Sawu sea water from Cakalang catch tends to increase at a temperature of 26o
C and
decreases at a temperature of 30.28o
C.
Figure 5. Relationship of sea surface temperature to Cakalang catches
3.2. Potential Area Predictions Catching Cakalang
The results of data analysis using indicate a very strong relationship between oceanographic
parameters, especially chlorophyll-a, where the higher the concentration of chlorophyll-a the
higher the catch of Cakalang, while for the sea surface temperature the lower the variation in
sea surface temperature the higher the catch Cakalang, thus predicting the potential area of
Cakalang catch is determined based on areas that have high chlorophyll-a concentrations and
cold sea surface temperatures. In the waters of the Savu Sea based on the results of 15 years of
image processing for the period 2003-2017, it was found that there were quite high areas of
chlorophyll-a conduction and colder sea surface temperatures in the East (June-August) and
early Transition II (September) . The area is presented in Figure 6.

4. CONCLUSION
Based on the results of data analysis, the variation of chlorophyll-a and SPL is very influential
with the catches of Cakalang in the waters of the sea of Sawu. And based on the results of
image processing for 15 years, the period 2002-2017 shows that chlorophyll-a construction
increases in the East season (June-August) and at the beginning of Transition II (September),
thus this season has the potential to catch Cakalang Fish.
