Abstract

Volcanoes are mountains that are formed as a result of eruption material accumulating around the center of an eruption or a mountain formed from a magma eruption. Volcanoes are only found in certain places, namely in the mid-ocean ridge, at the point where two plates of the Earth's crust meet, and at hot spots on the earth where magma is released, on continents and in oceans. Indonesia is a country with active volcanoes formed due to subduction zones between three tectonic plates, namely the Eurasian plate, the Indo-Australian plate and the Pacific plate. The location of the research was carried out in the Soputan Volcano Area, by taking two samples, namely two different rock types in the study area. This study aims to determine the elemental composition of the rock and rock mineral types in Soputan Volcano. Using SEM-EDX and FTIR.

Abstract

As one of the countries in the tropical region, Indonesia is blessed with various energy resources, one of which is geothermal energy. The existence of geothermal sources on the surface is reflected in the appearance of manifestations to the earth's surface, namely hot springs, fumaroles, etc. This study described the distribution of soil surface temperature to determine the surface temperature and the direction of the surface temperature opening around the Palu Koro Fault, Central Sulawesi. This study used remote sensing methods with thermal infrared channels recorded in 2015, 2017, 2018, 2019, and 2020. The results showed that the ground surface temperature in the geothermal potential area ranges from 31,5501°C - 38,8913°C, and the direction of the temperature opening is in the northwest to the southwest to the Southeast and is getting closer to the Palu Koro Fault.

Abstract

Bolaang Mongondow is an area that has an active volcano, namely the Ambang volcano, which is located in the village of Bakan. The existence of hot spring manifestations that appear indicates the potential for geothermal energy in the area. However, until now, geothermal potential in the area has not been developed due to a lack of knowledge about determining geothermal potential. For this reason, research on reservoir characteristics such as fluid type and reservoir temperature estimation is carried out. The method used in this research is the geochemical analysis of the fluid in the form of the percentage of fluid content and the calculation of the geothermometer. Fluid type analysis was determined based on plotting on ternary Na-K-Mg diagrams. While the reservoir temperature estimation is determined using the Na-K geothermometer equation. From the physical-chemical analysis of fluids in Bakan hot springs, it was found that the type of fluid in the Bakan area was immature water. Based on the estimated reservoir temperature calculation using a Na-K Geothermometer, the subsurface temperature ranges from 235 ℃ - 242 ℃ and includes a High-temperature reservoir.

Abstract

Geothermal is one of the alternative energy sources that are classified as new and renewable (new and renewable). This is because geothermal energy sources are still relatively new and are said to be renewable because production waste in the form of water is re-injected and produces a recycle process that allows sustainability. The process of exploration, exploitation and production does not produce toxic gas emissions. In terms of prospects, geothermal itself is a promising energy in the future because the source is heat from within the earth that will never run out. One of the areas in North Sulawesi that has the potential for geothermal project development is located in the Tomohon area, North Sulawesi Province. Based on the preliminary survey that has been carried out, at this location found manifestations in the form of hot springs located in the Pine Forest. The purpose of this study was to determine the type of fluid and functional groups of molecules manifesting hot springs in the Tomohon pine forest tourism area. Analysis of the ion content in the fluid using spectrophotometer characterization, and analysis of molecular functional groups using FTIR (Fourier Transform Infra Red) spectroscopy. The results showed that the type of fluid manifestation of the hot springs in the Tomohon Pine Forest Tourism Area has the type of bicarbonate (HCO3). Analysis of functional groups of fluid molecules in the manifestation of hot springs in the Tomohon Pine Forest Tourism Area has functional groups C=O, C≡C and O-H.

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

Geothermal is one of the natural resources that has great potential to be used as a renewable energy. The existence of geothermal resource on the surface is reflected by the presence of the geothermal manifestations on earth surface. This research was conducted to map the shallow subsurface temperature and determine the temperature gradient pattern of the geothermal manifestation in Noongan Tiga Village, Minahasa. This research uses observation method by measuring the temperature at the depth of 3 cm, 9 cm, and 15 cm in the morning, daytime, and the afternoon at 10 different points. The results showed that in that in the morning the temperature average reached 42,03 0C at the depth of 3 cm, 50,09 0C at the depth of 9 cm, and 60,26 0C at the depth of 15 cm. In the daytime, the temperature average rises to 59,2 0C at the depth of 3 cm, 66,01 0C at the depth of 9 cm, and 76,16 0C at the depth of 15 cm. While in the afternoon the temperature average reaching 41,28 0C at the depth of 3 cm, 49,46 0C at the depth of 9 cm, and 59,38 0C at the depth of 15 cm. The temperature gradient obtained shows an increase in temperature where the deeper you go, the temperature increases, with a linear temperature gradient pattern to the northeast.

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

North Sulawesi has a fairly large geothermal potential, this is evidenced by the emergence of several types of geothermal manifestations, one of which is in the village of Tempang. The purpose of this study was to determine the microstructure of rocks and the types of rocks contained in the rocks in the manifestation area in the village of Tempang. The method that will be used in this research is to analyze in the laboratory using SEM-EDX and FTIR. The results showed that the mineral content and types of minerals around the geothermal manifestation in the form of steaming ground had 3 mineral elements, namely oxygen, silica, and aluminum. The percentage results from EDX for sample 1 contained Oxygen (O) 43.72%, Silica (Si) 54.12%, and Aluminum (Al) 2.16%. For sample 2, the content of oxygen (O) is 51.10% and silica (Si) is 48.90%. This is in accordance with FTIR measurements obtained that the mineral type of steaming ground rocks in Tempang Village is Quartz (SiO2).
