Abstract

The increasing population of the world's population results in the need for energy to continue to increase, therefore the Indonesian government develops energy outside of fossil fuels, one of which is geothermal. Geothermal is one of the alternative energy source that is relatively new and renewable and can be renewed because production waste in the form of water is re-injected and produces a recycle process that allows sustainability. Geological surveys, geochemical surveys, and geophysical surveys are characterizations that need to be carried out in describing geothermal potential. The purpose of this study was to determine the type of fluid and molecular functional groups of hot springs in Tempang Village, Minahasa Regency. With the geochemical method using a spectrophotometer and FTIR (Fourier Transform Infra Red) spectroscopy, it is known that the type of fluid in the hot springs in Tempang Village is Bicarbonate (HCO3) type with a content of 69 mg/L and the molecular functional group is O-H and C=O.

Abstract

The Solar Power Plant (PLTS) represents one of the pioneering electricity producers established at Manado State University. The aforementioned solar cell technology is a mechanism that effectively transforms solar energy into electrical energy. Indonesia, being situated on the equator and endowed with ample sun resources, stands to benefit significantly from the adoption of solar energy, thus enhancing its effectiveness. This study employs a quantitative methodology with a descriptive framework to examine the impact of light intensity on the voltage and current of solar panels. Based on the obtained measurements, it can be observed that the intensity of the sun is directly proportional to its brightness, assuming that there is no cloud cover. In ideal bright conditions, the maximum duration for the absorption of solar energy in a single day can extend up to 9 hours. On the contrary, the duration of optimal absorption during overcast or rainy weather conditions is limited to a maximum of five hours during a single day. The calculations were conducted using the average power generated on the initial day, which amounted to 30,299.76 kilowatt-hours per day, and on the subsequent day, which totaled 40,991.22 kilowatt-hours per day. There exists a positive correlation between the intensity of solar radiation and the performance of solar panels, whereby an increase in intensity leads to a corresponding increase in panel performance.

Abstract

The utilization of renewable energy has become a major focus in an effort to reduce dependence on fossil energy sources and reduce negative impacts on the environment, making it important to increase the use of clean and renewable energy. One of the biggest challenges in the application of renewable energy is efficient and sustainable energy storage. In this case, supercapacitors have proven to be a solution as an efficient and sustainable energy storage device. In this study, water hyacinth biomass material was tested as a supercapacitor electrode which was influenced by variations in Na2SO4 electrolyte, namely 1M, 2M, and 3 M, which produced voltages of 1.037 V, 1.404 V, and 1.647 V respectively and electric currents of 18.56 mA, 23.32 mA, and 32.34 mA. From the results of this study, it was found that the sample with an electrolyte concentration of Na2SO4 3 M had higher voltage and amperage values, which amounted to 1.654 V and 32.34 mA due to the greater number of Na+ and SO42- ions in the electrolyte. So it can be concluded that the variation of Na2SO4 electrolyte concentration of 1 M, 2 M, and 3 M results in an increase in the value of voltage and electric current produced by supercapacitors.
