Abstract

Geothermal is a renewable energy source that occurs naturally beneath the earth's surface. This energy source comes from heating magma to rocks and water along with the elements contained in the earth's crust. North Sulawesi has the potential as a geothermal development area, either directly or indirectly. The research location in Pinaesaan Village has geothermal potential because it’s characterized by the presence of hot springs and is included in the Geothermal Work Area Kotamobagu. The purpose of this study was to determine the type of fluid and molecular functional groups of hot springs in Pinaesaan Village, South Minahasa Regency. By geochemical method using Cl-SO4-HCO3 diagram and FTIR, it’s known that the type of hot spring fluid in Pinaesaan Village is Chloride (Cl) type, and the molecular functional groups are C=O, where the constituents of the main chain C bind to Cl (Chloride) which corresponds to the result of fluid type.

Abstract

Indonesia is a country with great geothermal potential because it is located at the meeting point of three large plates, and North Sulawesi is right in the ring of fire area, so it has large reserves of geothermal energy. The research area located in Karumenga Village, North Langowan District, Minahasa Regency, North Sulawesi Province was chosen as the research location because in that area there are surface manifestations in the form of hot springs which are estimated to come from a geothermal system. The purpose of this study was to determine the fluid characteristics and reservoir temperature estimation at the research site using geochemical methods andanalysis was carried out using the Na-K-Mg geo-indicator and the Na-K Giggenbach geothermometer. After plotting laboratory chemistry data on Giggenbach's Na-K-Mg ternary diagram, it shows that the fluid characteristics of the hot springs at the research site are partial equilibrium water where the fluid has partially changed so that it is not completely in a state of equilibrium. and based on calculations using a Na-K geothermometer, it was found that the estimated temperature of the hot spring reservoir in Karumenga Village, North Langowan District is 209.638 oC and is included in the medium enthalpy system.

Abstract

Geothermal is a source of thermal energy contained in hot water, rock, water vapor, and other gases and minerals that are genetically inseparable from a geothermal system. This energy comes from heating water and rocks and other elements contained in geothermal energy stored in the earth's crust. Energy needs are increasing, various efforts are made to take advantage of the potential that exists in Indonesia, one of which is geothermal potential. Geothermal energy is a renewable natural resource with high potential and is one of the preferred energy sources in energy diversity. The existence of geothermal sources, marked by the presence of geothermal manifestations emerging to the surface, one of which is in Tompaso Baru District. The fluid samples were then tested in the laboratory, then data processing was carried out using the fluid geochemical method in the form of calculating the percentage of the Na-K-Mg geoindicator to determine the type of fluid and a geothermometer to determine the estimated reservoir temperature. By using the calculation of the percentage of chemical content from the laboratory test results Na/1000+K/100+√Mg and plotting a ternary diagram of a partial equilibrium waters type of geothermal fluid, namely a condition where the fluid has partially changed so that it is not fully in equilibrium, and calculations using a silica geothermometer the estimated reservoir temperature is 191.1078ºC, which is the type of reservoir with medium temperature.

Abstract

Lake Linow is one of the volcanic lakes that has geothermal activity characterized by geothermal manifestations in the form of hot springs that appear on the surface. The purpose of this research is to study the type of fluid and estimate the reservoir temperature. The methods used in this research are ion analysis of fluid content using spectrometry, pH, and physical analysis of fluids in the form of physical appearance manifestations of hot springs. The results showed that the hot springs in Lake Linow are immature water types with a high percentage of Mg concentration. It is interpreted that there is a process of dilution with other elements and mixing with meteoric water which is rich in Mg elements. Calculations using water geothermometer equations on hot spring samples in the area are estimated to have a reservoir temperature of 92.85°C-127.9°C

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 Lahendong Geothermal Power Plant (PLTP) is the largest power plant in North Sulawesi. Turbine is one of the important components in a power plan, so performance and efficiency must be considered. Environmental temperatures that change on a daily basis can potentially affect turbine performance and efficiency. Therefore, it is necessary to analyze the turbine to determine whether the ambient temperature can affect the performance and efficiency of the turbine. The results of the study for 14 days at 10.00 and 22.00 showed differences in the value of turbine performance and efficiency. The turbine performance value is greater during the day than at night. Turbine efficiency is affected by the ambient temperature, when the ambient temperature increases there is a decrease in efficiency and when the temperature decreases there is an increase in turbine efficiency
