Abstract

The location of Indonesia, which is located between three major tectonic plates, has an advantage in the field of alternative energy, namely geothermal heat. This research was conducted in order to facilitate the government and the community in North Sumatra Province regarding the existing geothermal potential. Geothermal energy or can be called geothermal is heat energy contained in water fluid or in the form of steam, liquid, or a mixture of both which is at a depth of more than 1 kilometer below the earth's surface. Indonesia has a geothermal potential of 40% of the total geothermal potential in the world, Indonesia is in second place, which is 23.76 GigaWatt (GW). One example is in North Sumatra in the Sarulla (330 MW) and Sibayak (120 MW) and Dolok Marawa (38 MW) areas. This study aims to create a mapping of geothermal potential in the province of North Sumatra using Quantum GIS by conducting literature studies, data collection, data management, and map visualization on Quantum GIS. reduce the use of fossil energy that is not friendly to the environment. The results show that the largest Geothermal Working Capacity Area (WKP) in North Sumatera is in South Tepanuli Regency with a total of 1,046 MW in Sibual Buali WKP and the second highest is Mandailing Regency of 240 MW.

Abstract

Renewable energy that is now widely loved is solar energy, which can be converted into electrical energy with the help of solar panels. Solar panels are made of semiconductor silicon which absorbs photons from the sun's energy. However, the sun does not only produce photons which can be converted into electrical energy, but there is also heat energy which can increase the temperature of the solar panels which can reduce the performance of the solar panels. Therefor researchers conducted research to reduce the temperature of solar panels by using the monocrystalline solar panel cooling method using mineral oil with the immersion cooling technique. However, from the experimental data in the field, it was found that the results were not good where solar panels without cooling were more than solar panels with cooling. The anova analysis test which was continued with the Tukey method confirmed that the voltage and current of the uncooled solar panels were superior, namely 4.48 V and 0.94 A. Solar panels with a 3cm cooling liquid variation produced a power of 3.93 W while non-liquid solar panels The cooler produces a power of 4.81 W, so research on cooling solar panels using liquid mineral oil with immersion cooling techniques has not succeeded in increasing the performance of solar panels and cannot be applied to PLTS.
