Abstract

Geothermal energy is the heat stored within the Earth’s subsurface rocks and the fluids contained within them. Indonesia, located on the Ring of Fire, has significant geothermal potential, particularly in North Sulawesi. This study aims to assess the geothermal energy potential in Sawangan Village, North Minahasa Regency, specifically at the Kepangian River hot springs. The research was conducted by analyzing the fluid characteristics and estimating the geothermal reservoir temperature using geochemical fluid analysis and geothermometer calculations. The analysis Involved laboratory testing of fluid samples, followed by data processing using Na-K and silica geothermometers, and plotting on a Na-K-Mg ternary diagram. The results indicate that the fluid type at the Kepangian River hot springs is immature water, with an estimated reservoir temperature ranging from 240.04°C to 267.01°C, which classifies it as a high-temperature reservoir.

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

The need for energy in everyday life is very important, geothermal energy has the potential to become an energy source for power plants. Indonesia has one of the largest geothermal potentials, because Indonesia is located in the Ring of Fire. One of the provinces known for its abundance of geothermal energy is North Sulawesi. The purpose of this study is to determine the characteristics of this geothermal manifestation. The method used is the Cl-Li-B Geoindicator to determine the outflow zone or upflow zone of a geothermal system. The results of the study show that the manifestation has a temperature of 39⁰C with a pH of 6.39 containing a higher chloride (Cl) content than Lithium (Li) and Boron (B), the chloride (Cl) content has a percentage of 82.3529% while for Lithium (Li) has a percentage of 11.7647% and Boron (B) has a percentage of 5.8823%. The data shows that of the three parameters studied, the relatively low B/Cl ratio indicates that the hot spring comes from an old geothermal reservoir and chloride (Cl) has the highest percentage of content, it can be concluded that this manifestation is in the outflow zone
