Electric generation using the photovoltaic (PV) effect is considered ideal in South Sumatra as a response to the government policy to increase the utilization of renewable energy to support the depletion of conventional energy. PV panels can be installed in a fishing village in the Sungsang Estuary. This paper examined the eligibility analysis for the installation of PV panels on brackish water. In this research, two Panels are installed, the first one is floating over a water body, and the second is ground mounted as a comparison of electricity produced and efficiency. The Jsc floating and ground mounting differ in 0.4435 A. The measured Jload in floating PV panels is 0.3900 A higher than the ground mounting. The  measured Voc at the floating PV panels is 0.2935 V higher, and the Vload of the floating PV panel is 3.0742 V higher than the ground mount. The differences are due to the floating PV panel surface temperature being lower than ground mounting. Electricity generated by floating PV panels is averagely 11.89 Watt higher, and the efficiency is 4% higher than that of ground installation. This experiment also shows that PV panels can be installed over brackish water in the fishing village of Sungsang Estuary.

Abstract The Kenyan photovoltaic industry has been growing steadily in recent years. Since 1990 more than 2.5 megawatts of photovoltaic capacity have been sold in Kenya and 60% of these sales have gone into home systems as part of new energy supplies. The demand for energy in Kenya exceeds the supply and for this reason renewable energy is regarded a priority in the energy sector. A solution to this problem lies in four areas: technology development, environmental protection, energy economics and socio-cultural adjustments. This paper discusses the state of current research and applications of stand-alone building-integrated PV home systems by looking at the possibilities and limitations in this developing country. Houses need a PV panel-surface area of about 36m2 to meet basic energy needs.

The surface temperature of PV panel has an adverse impact on its performance. The several electrical parameters of PV panel, such as open circuit voltage, short circuit current, power output and fill factor depends on the surface temperature of PV panel. In the present study, an experimental work was carried out to investigate the influence of PV panel surface temperature on its electrical parameters. The results obtained from this experimental study show a significant reduction in the performance of PV panel with an increase in panel surface temperature. A 5W PV panel experienced a 0.4% decrease in open circuit voltage for every 1°C increase in panel surface temperature. Similarly, there was 0.6% and 0.32% decrease in maximum power output and in fill factor, respectively, for every 1°C increase in panel surface temperature. On the other hand, the short circuit current increases with the increase in surface temperature at the rate of 0.09%/°C.

In this work, was considered the thesis that the optic properties of anti-reflecting and the satin-like glasses can improve the efficiency of solar panels that use plastic covertures or conventional glasses as coverage. The infrared radiation that is not turned into electricity with the conventional photovoltaic cells, increments the panel surface temperature, of the supporting structure and of the photovoltaic cells. For above 35oC it is possible that some cells stop converting the visible light in electricity due toparameters dispersion effect, with this, the efficiency of electric generation is diminished. In the electromagnetic spectrum, the wavelength of infrared radiation is since 800nm, the anti-reflecting glasses transmittance is since430 to 680 nm, while the satin-like glassestransmittance issince 500 to 600nm, therefore for thiscause the infrared transmittance is not observed. In this work, it was proved that the use of anti-reflecting glasses and satin-like glasses improves the conventional solar panels efficiency. The results suggest an efficiency of 31.6 % of solar energy conversion with the anti-reflecting glass, and 36% with the satin-like glass, when these were used as cover panel photovoltaic.

The 19Th Century

The article studies the system of pre-conditions that caused the onset of the uniat clergy’s movement towards Orthodoxy in the Russian Empire in the beginning of the 19th century. The author comes to the conclusion that the tendency of the uniat clergy going back to Orthodoxy was the result of certain historic conditions, such as: 1) constant changes in the government policy during the reign of Emperor Pavel I and Emperor Alexander I; 2) increasing latinization of the uniat church service after 1797 and Latin proselytism that were the result of the distrust of the uniats on the part of Roman curia and representatives of Polish Catholic Church of Latin church service; 3) ecclesiastical contradictions made at the Brest Church Union conclusion; 4) division of the uniat clergy into discordant groups and the increase of their opposition to each other on the issue of latinization in the first decades of the 19th century. The combination of those conditions was a unique phenomenon that never repeated itself anywhere.

Palm oil industry in Indonesia has been growing rapidly. But, unfortunately the growth is only effective on upstream industry with low value products, such that potential downstream value added are not explored proportionally. The government is therefore in the process of developing an appropriate policy to strengthen the national palm oil downstream industry. This paper proposes that an approriate policy for developing palm oil downstream industry could be derived from the maps of value chain and existing technology capability of the industry. The result recommends that government policy should emphasize on the supply of raw materials, infrastructure and utilities, as well as developing the missing value chain industry, especially ethoxylation and sulfonation.

Penelitian ini bertujuan untuk mengkaji daya saing komoditi kakao di Sulawesi Tengah dan melihat peran pemerintah dalam meningkatkan daya saing komoditi kakao. Data primer berasal dari observasi, wawancara dan kuesioner, sementara data sekunder berasal dari instansi terkait. Metode analisis menggunakan Policy Analysis Matrix (PAM) dan analisis sensitivitas. Penelitian ini menemukan bahwa nilai PCR Kabupaten Parigi Moutong 0,589 dan Kabupaten Sigi 0,396. Sedangkan nilai DRC Kabupaten Parigi Moutong 0,387 dan Kabupaten Sigi 0,319. Hal tersebut mengindikasikan bahwa usahatani komoditi kakao di Sulawesi Tengah memiliki daya saing, namun tidak menguntungkan secara ekonomi karena Sulawesi Tengah menghasilkan biji kakao yang tidak difermentasi akibatnya petani menerima harga rendah. Berdasarkan hasil analisis, pemerintah belum memberikan proteksi terhadap harga biji kakao dalam negeri melalui harga referensi biji kakao sehingga harga biji kakao didaerah penelitian masih tergolong rendah jika dibandingkan dengan harga di pasar internasional. Sementara terhadap input, pemerintah telah memberikan kebijakan subsidi kepada petani, namun implementasinya masih perlu perbaikan terutama terkait penyaluran dan pengelolaan bantuan agar merata. Kajian ini merekomendasikan masih diperlukan kebijakan pemerintah baik terhadap input maupun output untuk meningkatkan produktivitas, menurunkan biaya produksi dan menaikkan harga jual biji kakao, sehingga dapat meningkatkan daya saing biji kakao. The purpose of this study is to assess the competitiveness of cocoa in Central Sulawesi and to investigate the role of government in improving the competitiveness of cocoa. The primary data were generated through observation, interviews and some questionnaires. The secondary data were obtained from the agency or the institution related to the research. This study uses the Policy Analysis Matrix (PAM) and sensitivity analysis. The study found that the PCR value for Parigi Moutong district was 0.589 and Sigi district was 0.396. While, the DRC value for Parigi Moutong district was 0.387 and Sigi district was 0.319. This indicates that cocoa beans farming in Central Sulawesi has competitiveness, but not economically beneficial because Central Sulawesi produces unfermented cocoa beans consequently farmers receive low prices. Based on the results of the government's impact on output analysis, the government did not provide protection for domestic cocoa seed prices through the reference price of cocoa beans, consequently the price of domestic cocoa beans, particularly in the research area, was relatively low compared to the price of cocoa beans at the international market. Seen from the government policy on inputs, the government have provided subsidies to farmers but they need to improve the distribution and management of aid to be evenly distributed. It is necessary to set up good government policy on inputs and outputs in order to increase cocoa seed productivity, decrease production cost and increase the price which simultaneously can improve its competitiveness in the research location.

The aim of this study is to investigate the factors influencing the entrepreneurial success of rural women entrepreneurs in Bangladesh. Non-probability sampling specifically convenience sampling is used to draw the sample and data is collected using the self-administered survey. Regression analysis and descriptive statistics are used to analyze the data. The study discloses that motivational factors, government policy and financial support have significant influence on the rural women entrepreneurial success in Bangladesh. Due to lack of suitable training and proper development as well as ICT knowledge, the rural women of Bangladesh could not accomplish the achievement. Half of the total populations of Bangladesh are female and most of them live in rural areas. Therefore, the government and the policymakers in Bangladesh should develop the potential of rural women entrepreneurs by providing development facilities, proper training, and ICT knowledge.
