Gedangan village, a dairy farming center, has many biogas reactors that are used for cooking and lighting petromax lamps. Previous community service activities resulted in the construction of three Biogas Power Plants (PLT-Biogas) capable of producing 15 kW of power but which were not fully utilized. Participatory Rural Appraisal (PRA) is the approach method used to actively involve the community in the program. To optimize the PLT-Biogas, the service team rearranges the equipment and replaces the UPS with an inverter and battery charger before constructing a street lighting electricity network that can be used by the entire community. The next step is to provide operational and maintenance training for the long-term use of PLT-Biogas. As a result, the initial stage of electrical energy is currently used for street lighting in two hamlets, as well as freezers and water pumps, with a potential savings of 2,775.6 kWh per year. By converting biogas energy to electricity, this community service activity can help to kickstart the realization of an energy self-sufficient village.

The use of biomass as a renewable energy source is currently a reality, mainly due to the role it can play in replacing fossil energy sources. Within this possibility, coal substitution in the production of electric energy presents itself as a strong alternative with high potential, mostly due to the possibility of contributing to the decarbonization of energy production while, at the same time, contributing to the circularization of energy generation processes. This can be achieved through the use of biomass waste forms, which have undergone a process of improving their properties, such as torrefaction. However, for this to be viable, it is necessary that the biomass has a set of characteristics similar to those of coal, such that its use may occur in previously installed systems. In particular, with respect to grindability, which is associated with one of the core equipment technologies of coal-fired power plants—the coal mill. The objective of the present study is to determine the potential of certain residues with agroforestry origins as a replacement for coal in power generation by using empirical methods. Selected materials—namely, almond shells, kiwifruit pruning, vine pruning, olive pomace, pine woodchips, and eucalyptus woodchips—are characterized in this regard. The materials were characterized in the laboratory and submitted to a torrefaction process at 300 °C. Then, the Statistical Grindability Index and the Hardgrove Grindability Index were determined, using empirical methods derived from coal analysis. The results obtained indicate the good potential of the studied biomasses for use in large-scale torrefaction processes and as replacements for coal in the generation of electrical energy. However, further tests are still needed, particularly relating to the definition of the ideal parameters of the torrefaction process, in order to optimize the grindability of the materials.

The utilization of rice husk as an alternative fuel for the power plant in Indonesia is still under study. In present, steam power plants in Indonesia are still using coal fuel. This study was conducted to obtain data on the development potential of rice husk within 12 years duration. The potential of rice husk for each province was obtained by analyzing the rice production of 22 provinces that have rice production greater than 1 million tons per year. The study shows that the potential of rice husk and potential electrical energy increased by about 36.8% within 12 years or an average increase of around 3.1% per year. For the potential of rice husk in 22 provinces, the total gain was estimated 12.76 × 106 tons which is equivalent to 6.62 × 106 tons of coal or equivalent to 3.68 × 106 tons of oil. The available capacity of power plants is around 5,664 MW with the potential of electric energy is around 49,622 GWh. This potential is equivalent to 50% of the energy needs of coal in Indonesia in 2011, which was about 99,312 GWh. In conclusion, rice husk is indeed potential to be used as an alternative fuel in power plants thanks to its increasing yearly production and ability for distribution to all provinces in Indonesia.

Investments in energy sector are usually long term processes both in construction and exploitation phase, and therefore require many conditions to be satisfied, mostly from legislative and technical sector. While the legislative can change in accordance with economy activities in the country, technical data (on-site measurements) which are the main base for energy facility design, need to be reliable as much as possible. Wind energy has a significant global potential which exceeds the world?s electrical energy consumptions. This paper presents the estimation of wind energy potentials in Montenegro, based on all previous available studies in this field. The wind energy potential in Montenegro is based on a combination of 3-D numerical simulations of wind fields on the entire territory, and comprehensive on-site measurements. The preliminary studies show that there is a potential of areas with high and mean values of a capacity factor about 400 MW, and annual production of 900 GWh of electric energy. The share of wind parks in the total installed power in Montenegro is planned to be about 8%, while an adequate ratio of wind parks in an annual production from renewable sources (large hydro power plants are included here) is estimated to be 11.4%. The paper presents the current state of art in the field of building of wind parks in Montenegro. A particular attention was paid to the legislation framework and strategic documents in the energy area in Montenegro.

Solar energy, which is essential for all on earth, is clean and plentiful and can be transformed into electrical energy using photovoltaic (PV) systems. The generation of energy using different types of PV solar panel mountings viz. fixed, tracking, and adjustable, depends on a variety of factors such as sun intensity, relative humidity, cloud cover, and heat buildup. This paper reviews the various parameters which influence the performance of solar power plants. Further, the performance comparison of fixed and tracking PV systems shows that in comparison to the classical fixed-position PV systems, the tracking type of PV systems capture much more solar energy and thus produce substantially higher output power. Furthermore, consideration is also given to design variables which should be taken into account during the initial stage of engineering of a plant to achieve better performances and outcomes from the generation of a solar power plant.

The Sophistication of digital media provides how easy to access about information in almost all aspects of society. The leap of technological sophistication is too rapid makes the negative impact of digital media increasingly disguised. This community service aims to improve the understanding of housewives regarding the negative impact of digital media on children. Using the adult approach method, this service activity actually looks for cases from within the community itself, and guides the community to find solutions to problems from themselves. At the end of the activity, it was known that housewives in the Demen, Pakem, Sleman area had knowledge of the negative impact of digital media on children, but awareness of its long-term impact still became homeworks not only for the mothers themselves, but also the other stakeholders.
