Abstract

To meet future energy needs, the Indonesian government has developed alternative energy sources: geothermal energy. Rano Raindang is one of the areas with a geothermal field due to several geothermal manifestations, such as hot springs. This study aims to examine the fluid type, the reservoir temperature estimation, and the functional group of hot springs. The method used is a geoindicator of Na, K, Mg, Cl, SO4, and HCO3, combining spectrophotometry and FTIR spectroscopy. Research results show that the type of hot spring fluid around Rano Raindang with geoindicators Na, K, Mg is immature waters, this is because the type of hot spring fluid around Rano Raindang has undergone a mixing process, while the geoindicators Cl, SO4, HCO3 are bicarbonate (HCO3) types. This corresponds to the results of measurements using FTIR spectroscopy. The estimated reservoir temperature in the area is 193.66 °C and is included in the medium-temperature geothermal system, as the temperature around Rano Raindang is between 125–225 °C. The functional group of hot spring molecules around Rano Raindang has functional groups C=O and O-H.

Abstract

Geothermal is a source of heat energy contained in hot water, rocks, water vapor as well as gases and minerals and others that cannot be genetically separated from a geothermal system. Geothermal energy is a renewable natural resource with high potential. The source of this energy comes from heating magma against water rocks together with elements contained in the earth's crust. North Sulawesi has the potential to become a geothermal development area, both directly and indirectly. The existence of hot springs shows that the research location in Sawangan Village has geothermal potential. This research aims to determine the fluid type and molecular functional groups of hot springs in Sawangan Village, North Minahasa Regency, North Sulawesi Province. Using geochemical methods using Cl-SO2-HCO3 and FTIR diagrams, it is known that the type of hot spring fluid in Sawangan Village is Bicarbonate (HCO3) and the molecular functional group is C=O, where the parent chain C binds HCO3 (Bicarbonate) which corresponds to fluid type results.

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.

Abstract

North Sulawesi has considerable geothermal potential as evidenced by the emergence of several types of geothermal manifestations, one of which is located in Kanonang village, precisely on the hill of Kasih Kanonang. The purpose of this research is to determine the rock structure and type of rock contained in the rock in the manifestation area located on the hill of love kanonang. The method to be used in this research is to analyze in the laboratory using SEM-EDX tools and FTIR tools. The results showed that the mineral content and mineral types of geothermal manifestations of hot springs in kanonang love hill have 3 elements namely Oxygen, Silica, and Aluminum with a percentage content of O 66.60%, Si 31.25%, and Al 0.73%.

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.
