Aims: Residential sector is the largest electricity consumer in Nigeria. But they also contribute heavily to the climate change through their choice of energy. Mostly prefer source is the fossil fuel for electricity generation despite the growing awareness of the need to reduce greenhouse gas emissions by embracing renewable energy technologies across the globe. Hence, this study investigated the factors influencing solar PV utilization in Akure. Study Design: The study employed a survey research design. Place and Duration of Study: Three residential estates in Akure, Ondo State, Nigeria formed the study areas. The study was conducted between June 2019 and July 2019. Methodology: The study surveyed 292 households located in the three residential estates in Akure, Ondo State and 219 retrieved questionnaire were found usable for the analysis. Data was analysed using the mean ranking of the influencing factors. Results: The results revealed that the highest ranking factor influencing utilization of Solar PV for energy services is that Solar PV is a good backup against power failure. This is as a result of the erratic power supply in Nigeria which has not only failed to meet the need of household but also hampered economic growth. However, the least ranking factor influencing solar PV utilization for energy services is Ability to sell electricity to the national grid. Conclusion: Cooperation between private enterprises and relevant government agencies supported by ‘political will’ is required to promote the aforementioned factors influencing the solar PV utilization for energy services in Nigeria. Utilization of solar PV as an energy source for energy service ensure access to affordable, reliable, sustainable and modern energy for all. The research recommended that government support for solar PV intervention should be further encouraged.

Most rural people in Kenya rely principally on human and animal muscle power in their work as subsistence farmers, herdsmen, fisherman, or small-scale crop farmers. All the agricultural processes (ranging from ploughing to harvesting) are done largely by hand, with some help from draft animals and simple tools. Firewood is their principal cooking and heating fuel while kerosene in used for lighting. Their economic growth is hence blocked by the energy crisis. Due to their heavy dependence on biomass – mainly firewood, crop residues, and animal dung – they deprive the soil of essential nutrients and pose a threat to the agricultural lands due to deforestation and the resulting soil erosion. The problem of rural energy, therefore places the provision of food and other basic needs at risk. A technology which extracts a more useful and convenient form of fuel from biomass without destroying its fertilizer value than the traditional conversion method of direct combustion is highly desirable. Anaerobic digestion of agricultural residues generates biogas which can be used directly for lighting, cooking, electricity generation, or to power an IC engine for water pumping or milling. The remaining sludge forms a good fertilizer. This paper reviews the role of biomass in meeting Kenya's energy needs and how biogas can contribute in alleviating the rural energy crisis. Biogas production and utilization technology was introduced in Kenya in 1954 but by 1986 there were less than 200 installed biogas plants and less than 25% of these were operational. A survey of installed biogas plants (across the country) was carried out (using questionnaires and interviews) to identify the factors that have inhibited the adoption of biogas technology in Kenya; and the problems which have caused the failure of many of the installed plants. The paper gives a detailed discussion of the findings. The survey showed that amoung the reasons for nonadoption are: lack of capital and sufficient input materials (animal dung and water); limited dissemination of technical knowledge and experience to operate biogas plants; and the lack of credit and extension facilities. It was also found that problems such as scum build-up and corrosion, and the lack of sufficient knowledge on the operation and maintenance of the digesters especially on feeding and feedstock dilution (leading to low gas production) has resulted to many failures. The paper attempts to answer some of the problems which have resulted to the many failures and hindered widespread acceptance of biogas technology in Kenya. Finally the issue of dissemination is discussed.

This study aims to analyze the influence of biophysical, economic, location, socio-cultural, institutional and environmental aspects on the water supply and the need for clean water in Medan city. Clean water was originally consideredas social goods that were freely accessed. The need for clean water for the population in Medan city is heightened due to the population growth, the increase on economic activities such as industrial growth in small-scale, medium and large industries, the development of public facilities and the increasing welfare of the community. The primary and secondary data obtained from relevant agencies and public in Medan city are used in this study. The secondary data were obtained starting in 1990 - 2012, while primary data were obtained from 30 respondents. The analysis model used is the structural equation models. The results have shown that; (i) biophysical, economic, location, sociocultural, institutional, environmental aspects positively influence the water supply and the need for clean water; (ii) there is a greater influence of water needs on the water supply, as compared to the effect of water supply to the needs of clean water.

In the context of the energy revolution, integrated energy services have ushered in a period of opportunities for rapid development. To assess the demand of users of integrated energy services, we establish indexes of demand of integrated energy service users. We got the assessment model based on the analytic hierarchy process (AHP) and entropy weight method. The proposed assessment model is tested on 50 users, and K-means clustering algorithm is used to cluster users. The characteristics of the service requirements of each type are analysed.

Salah satu alasan yang kuat nelayan tangkap skala kecil tetap melaut meskipun mempunyai risiko tinggi karena peluang/prospek pendapatan/penerimaan yang tinggi pada satu saat. Risiko melaut tidak hanya membuat ketidakpastian tetapi juga karena risiko biaya operasional yang tinggi. Dihadapkan dengan kondisi biaya operasional yang  tinggi, nelayan menggunakan strategi yang berbeda, salah satunya melekat pada peran tengkulak. Dalam pandangan konvensional, pedagang perantara/ langgan sebagai hambatan bagi nelayan untuk menjadi kompetitif di pasar. Namun di negara berkembang seperti Indonesia, mereka memainkan peran penting sebagai "bantal sosial" dalam kehidupan nelayan skala kecil. Tujuan penelitian adalah menyelidiki tingkat kecenderungan keterikatan hubungan langgan/pedagang antara sebagai “bantal sosial” dengan nelayan di dua daerah penangkapan ikan yang menonjol di pantai utara dan pantai selatan Jawa. Analisis data dilakukan dengan metode analisis kuantitatif yaitu model analisis multinomial logistik. Hasil penelitian menunjukkan bahwa nelayan dari pantai utara cenderung sangat kuat hubungannya dengan perantara untuk kelangsungan hidupnya dibandingkan dengan nelayan di pantai selatan. Implikasi dari temuan tersebut bahwa peran sentral langgan/perantara/tengkulak/langgan merupakan bentuk hubungan yang bersifat ekonomi dimana kedua belah pihak bisa mengambil keuntungan. Pola hubungan bukan hanya sekedar sebagai penyangga, namun lebih dari itu yaitu berfungsi sebagai “bantal” sosial (social cushion) para nelayan. Hubungan seperti ini merupakan bentuk layanan dimana para nelayan bisa mendapatkan alternatif layanan jasa “kredit” dari para perantara/langgan/tengkulak. Bentuk layanan seperti yang diperankan oleh langgan/pedagang perantara selama ini belum bisa digantikan oleh lembaga pemerintah yang resmi, dimana pola hubungan tersebut sangat dibutuhkan oleh nelayan skala kecil. Pola hubungan tersebut selain dipengaruhi oleh lokasi, juga dipengaruhi oleh status kepemilikan kapal, lama kepemilikan kapal dan jumlah ABK.Title: The Role “Social Cushion” On The Livelihood Of Small Scale Fishers In JavaOne of the strong reason for small scale fishers to keep fishing despite high risk of fishing, is the prospect of high earning at one moment in time. Risk at fishery not only  create uncertaining but also risk high cost of fishing. Faced with such a high cost, fishers use different strategies, one of which is attached to the middlemen. Convientional views middlemen as an obstacle for fishers to be competitive in the market. Yet in developing country such us Indonesia, they play crucial role as a “social cushion” in the livelihood of small scale fishers. The purpose of research is to investigate the tendency of engagement relationships middleman as "social cushion" with fishermen in the fishing areas that stand out on the north coast and the south coast of Java. Data was analyzed using quantitative analysis method multinomial logistic analysis model. Results of this study show that fishers of the northern coast tend to strongly attach to middlemen for their survival compared with those in the southern coast.  Relationships with fishermen middlemen is a service, where fishermen can get alternative services "credit" from the middleman. Services such as that played by middleman has not been able to replace them by official government agencies, where this kind of relationship is needed by small-scale fishermen. The relationship patterns in addition affected by the location, also influenced by the status of ownership of the vessel, long time ship ownership and the number of crew.
