Abstract

Geothermal is a natural resource energy in the form of hot water or steam that forms in reservoirs within the earth through the heating of subsurface water by hot igneous rocks. Based on field surveys, the Sulili area shows characteristics of geothermal energy in the form of hot springs. The research aims to use the Na-K geothermometer to find out the temperature of the geothermal reservoir below the ground and the Na-K-Mg geothermometer to look into the type of fluid that is in the geothermal reservoir. The research employs the geochemical analysis method in conjunction with the Na-K geothermometer method. Reservoir subsurface temperature is estimated at EPU station 1 at 326.504°C, EPU station 2 at 473.369°C, and station EPU 3 at 456.508°C. According to the results, the hot springs at the three sites are chlorides with temperatures below ground that are part of the high-temperature geothermal system and are >225°C. The hot spring is in the immature water group. Based on the calculation, the Sulili Geothermal Field with an average reservoir temperature of 418°C is approximately 68.33 MWh. This is a simplified calculation, and actual energy output can vary based on several factors, including the specific characteristics of the geothermal reservoir and the efficiency of the power plant.

Abstract

Field surveys in the Sulili Region show geothermal characteristics in the form of manifestations, namely hot water springs. This study aims to determine the type of geothermal fluid in the study area based on the Na-K-Mg geothermometer method and then classify it based on trilinear and ternary diagrams. The results showed that the types of hot springs from the three hot springs in the study area were included in the chloride type with a percentage between 96.209% -96.651% which was plotted on the trilinear diagram. Based on the ternary diagram plotting, the geothermal fluid in the study area belongs to the immature water group. Based on the results of the study it can be concluded that the type of hot water springs in the study area is chloride with one of the hot springs included in the immature water group, namely EPU-1 hot water spring station, while two hot water spring stations, such as EPU-2 and EPU-3 stations cannot plotted due to the high levels of Mg at that station.

Abstract

Keberadaan bahan galian mangan di Desa Pattappa, Kecamatan Pujananting, Kabupaten Barru, Provinsi Sulawesi Selatan memberikan peluang besar untuk dikembangkan sebagai geowisata yang edukatif. Bahan galian mangan yang dapat diamati langsung di lapangan memiliki potensi besar sebagai sarana pendidikan bagi siswa SMK Geologi-Pertambangan, mahasiswa Teknik Pertambangan dan Teknik Geologi, serta masyarakat umum. Pemetaan ini bertujuan untuk memberikan informasi mengenai potensi geowisata berbasis geologi, yang tidak hanya akan berdampak positif pada perekonomian lokal, tetapi juga meningkatkan kesadaran masyarakat mengenai pelestarian alam dan pentingnya pendidikan geologi. Metode yang digunakan yaitu observasi lapangan untuk memetakan lokasi dan potensi bahan galian mangan, serta menilai aksesibilitas jalur transportasi menuju lokasi yang dapat dikembangkan menjadi geowisata. Hasil pemetaan menunjukkan bahwa lokasi bahan galian mangan memiliki luas 18.775 m² (18,775 ha) dan dapat dijangkau dengan jarak 1,44 km dari kantor Desa Pattappa menggunakan kendaraan roda dua, roda empat, atau berjalan kaki. Dengan pengembangan yang tepat, geowisata ini berpotensi memberikan nilai tambah bagi perekonomian desa dan memperkuat kesadaran tentang pemanfaatan serta pelestarian sumber daya alam secara berkelanjutan.

Abstract

In the Lipukasi area, Barru Regency, South Sulawesi Province, sulphide deposits and complex alteration processes have been discovered. However, information regarding the alteration and mineralisation that has developed in this area is not yet available, so further research is needed to identify the types of alteration and mineralisation present in the Lipukasi area, Barru Regency, South Sulawesi Province. The purpose of this study was to determine the type of hydrothermal alteration and mineralisation that developed in the study area. The analytical method used in this research first carried out megaskopis analysis to determine the physical properties of the sample. After that, laboratory analyses of mineragraphy and X-Ray Diffraction (XRD) were carried out. The results of megascopic analysis of the two research samples are an igneous rock with a fresh grey colour, a weathered yellowish-brown colour, a massive structure, an intermediate rock type, a crystalline texture, namely holocrystalline, a granularity, namely phaneroparabolic, a relationship, namely equigranular, and a crystal shape, namely euhedral. The minerals found from the results of mineralographic and XRD analysis are Hematite, mafic mineral, goethite, silica mineral,  sulphide mineral (galena, chalcopyrite, pyrite, covellite), quartz, and kaolinite. So it can be concluded the minerals found in the study area are hematite (Fe₂O₃), mafic minerals, silica minerals, goethite (FeO₂H), galena (PbS), covellite (CuS), chalcopyrite (CuFeS₂), pyrite (FeS₂), kaolinite and quartz (SiO₂). Based on the indicated mineral composition, the type of alteration that developed in the study area is propylitic
