Indonesia is a tropical country located on the equator. The average intensity of solar radiation in Indonesia is 4.8 kWh/m2. This makes Indonesia a country with new and ren ewable energy potential, one of which is solar panel technology. The first step that must be done in the process of installing solar panels in a place is to analyze the potential of solar energy. In this study, an analysis of the potential of solar energy as a new renewable energy source has been carried out at Budi Luhur University, North Petukangan, South Jakarta. Based on the research results, the maximum photovoltaic efficiency that can be achieved is 21.45%. During the day, the efficiency of the solar panels increases along with the ncrease in the value of the voltage obtained. However, the higher the panel temperature, the lower the efficiency of the solar panel. Therefore, a cooling system is needed to anticipate this.

Budi Luhur University in collaboration with residents of Pondok Lakah Permai Ciledug housing, collaborates in the field of household scale waste management to be used as biogas raw material. The problem faced by environmental managers is that waste is not transported then rot. To solve this problem, the waste is processed into biogas through a fermentation process. The fermentation process is used to break down organic waste into methane gas which can be used for cooking. The role of the community is needed to collect waste raw materials and sort organic and non-organic waste. The purpose of this community service activity is to empower residents to separate waste from household waste to be processed into biogas. The method used is to provide counseling and continue with the manufacture of a waste chopping blender to process the waste. The results of this service can be concluded that the first one has produced a biogas reactor unit and a waste crusher / blender, then after training to the target community on how to make a biogas reactor, the second conclusion is that the two communities can operate the tools that have been made and can also sort waste. as a raw material for biogas. In this activity, the community understands how to protect the environment and can operate a waste chopping biodigester and blender so that the waste that had been piling up is now processed into biogas.

ABSTRAKSalah satu faktor yang dapat mempengaruhi efisiensi panel surya adalah suhu pada modul panel surya. Efisiensi panel surya akan menurun seiring dengan naiknya suhu panel surya. Oleh karena itu, dibutuhkan suatu mekanisme pendinginan pada sistem panel surya untuk dapat meningkatkan efisiensi panel surya. Pada penelitian ini, dirancang sebuah sistem pendinginan panel surya dengan metode penyemprotan air dan pengontrolan suhu air. Jika suhu telah mencapai 40oC, pompa yang terdapat pada bak penampungan air akan bekerja mengalirkan air ke permukaan panel surya. Dengan demikian, suhu pada panel surya dapat dikontrol agar sesuai dengan set point yang diinginkan yakni di bawah 40oC. Sistem pengontrolan suhu air dengan peltier dan fan dilakukan untuk mengontrol suhu air di dalam bak penampungan air agar tetap berada pada suhu maksimal 39oC. Sistem pendinginan panel surya pada penelitian ini mampu meningkatkan daya keluaran panel surya sebesar 30,19%.Kata kunci: panel surya, pendingin, semprotan air, peltierÂ ABSTRACTThe solar panels efficiency can be affected by the the temperature of the solar panel module. It will decrease as the temperature of the solar panels increases. Therefore, a cooling mechanism in the solar panel system is needed to increase the efficiency of the solar panels. In this study, a solar panel cooling system was designed with the method of spraying water and controlling water temperature. If the temperature has reached 40oC, the pump in the water reservoir will work to circulate water to the surface of the solar panel. Thus, the temperature on the solar panel can be controlled to match the desired set point, which is below 40oC. The water temperature control system with peltier and fan is carried out to control the temperature of the water in the water reservoir so that it remains at the maximum temperature of 39oC. The solar panel cooling system in this study was able to increase the solar panel output power by 30.19% when using the cooling system.Keywords: solar panels, cooling, water spray, peltier

The integration of distributed generation allows the distribution network to operate in either on-grid or off-grid mode. In off-grid mode, the power supply from the main grid is interrupted, and distributed generation becomes the main source of power to meet the load's power demand. The absence of power supply from the main grid reduces the grid's ability to meet load power demand. The load power demand is larger than the distributed generation capacity, causing a power deficit in the network. This paper studies strategies for restoring power balance through optimal load shedding, taking into account the presence of priority loads that require power demand to be maintained and met. The optimization objective is to maximize the remaining load with an optimal composition so that the power loss is minimal. The load-shedding optimization uses a hybrid Grey Wolf Algorithm and Whale Optimization Algorithm (GW-WOA). The performance of GW-WOA is tested by load shedding optimization on a 118-bus IEEE radial distribution system integrated with 12 units of DG. The network loading factor variation consists of 80%, 100%, and 140% of the base load. Regarding all loading factors, the GW-WOA hybrid algorithm is superior to the standard GWO and WOA. The GW-WOA hybrid algorithm can converge faster to obtain the global optimal solution to realize power balance, overcome power deficit, maximize remaining load, and minimize power loss in the network. The GW-WOA hybrid algorithm has improved the performance of load-shedding optimization in isolated distribution networks with global optimal results and shorter iterations.
