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.

Abstract

Geothermal is a natural heat resource derived from the interaction between heat that has been emitted by hot rocks and water. Geothermal energy is pollution-free, sustainable, or renewable. Geothermal energy appears on the surface in the form of geothermal manifestations such as warm ground, steamy ground, hot springs. North Sulawesi has the potential to be the location of direct and indirect geothermal development. This study aims to determine the fluid type and molecular functional groups of hot springs in Sawangan Village, North Minahasa Regency, because this location has geothermal potential. By using the geochemical method of making diagrams , it is known that the fluid type of hot springs in Talawaan Bantik Village, Wori District is of the Birkabonat type and the molecular functional groups are C = O and O-H, where the parent chain, C, O and H bind (Bicarbonate) which corresponds to the fluid type results.
