Secara administratif Bendungan Pamukkulu terletak pada Desa Kale Ko’mara, Kecamatan Polombangkeng Utara, Kabupaten Takalar, Provinsi Sulawesi Selatan. Litologi pada Bendungan termasuk Formasi Batuan Gunungapi Baturape-Cindako yaitu lava dan breksi beserta retas-retas andesit. Metode penelitian berupa pemetaan permukaan dan pengeboran inti batuan. Berdasarkan investigasi geologi bawah permukaan, kelas batuan yang sesuai zonasi 3B yaitu pada Blok B1 (10-20m), Blok A3 (5-10m), dan Blok D (5-20m) dengan kelas batuan CH. Untuk zona 3A dengan kelas batuan CM terdapat pada Blok A3 (10-15m), Blok B1 (5-10m), dan Blok D (0-5m) dan zona 3C terdapat pada Blok A3 (1-5m), Blok B1 (5-10m), dan Blok D (0-5m) dengan kelas batuan CM. Dari hasil uji laboratorium mekanika batuan nilai Uji Kuat Tekan antara 33.36 MPa–67.24 MPa hal ini menunjukkan batuan memiliki nilai kekerasan dan kekuatan berkisar dari sedang sampai keras. Nilai Rock Quality Designation (RQD) pada lapisan atas 0-10m berkisar 13-68% dan lapisan 10-20m berkisar 83-99%. Analisis Fragmentasi batuan hasil blasting rata-rata boulder batuan berukuran 100cm ialah 18.74%. Rekomendasi dalam pembangunan bendungan pada area quarry yaitu perlunya penyesuaian blasting plan terhadap faktor-faktor geologi yang terdapat dilapangan agar fragmentasi dapat tercapai dengan baik.

Keerom Regency is one of the areas that has the potential for Batugamping mineral resources which is quite potential, this is evidenced by the existence of several mining business actors who are carrying out mining activities in the area. Based on the geological map of the Jayapura sheet (Taritatu Sheet) the distribution of limestone potential is quite evenly distributed in the Keerom Regency area. The distribution of limestone potential in Keerom Regency is spread in the Arso 1, Arso 4, Arso 10, Arso 13 areas to Senggi. Based on the results of the initial survey, mining activities in Keerom Regency have not been managed properly, because some mining sites have carried out mining activities but do not yet have legality, namely a mining permit (SIP), do not have a good and correct mine processing plan based on the mining stages, there are still locations where limestone is not yet known distribution, volume and even the amount of resources and reserves. The potential for limestone is a good investment opportunity if it is developed into a community mine that can provide added value to the community. Therefore, it is necessary to have geological mapping activities and also the calculation of resource values. In this case, it concerns the quantity and quality of deposits to be able to provide information as a mineral database for the community as land owners and is also very useful for the Keerom Regency government. This research aims to determine the amount of limestone volume which can later be used as data base information during mining activities. The research also utilized the Surfer 11 application for the creation of topographic maps and to calculate the number of limestone volumes. The research method that will be carried out is the Cross Section Method which is a special method for types of rock minerals.

Morphotectonics is a major factor in controlling the development of landforms and has an influence on river systems in the Ereunpalay area and its surroundings. This study uses a quantitative method, starting with a broad perspective and then moving on to a more focused and targeted approach. This tectonic geomorphological analysis uses several morphometric parameters, such as: Drainage Density (Dd), Bifurcation Ratio (Rb), Valley Floor Width to Valley Height Ratio (Vf), Mountain Front Sinousity (Smf), Hypsometric Curve and Hypsometric Integral (HI), and the Tectonic Activity Index (IAT). From the results of IAT calculations, it is found that the Ereunpalay area and its surroundings are in class one to three tectonic activities or commonly called moderate to very high class. The flow pattern of the river that dominates the study area is a parallel flow pattern which is controlled by the geological structure. Based on the results of the morphotectonic analysis, it was found that the Ereunpalay area and its surroundings have a morphological shape that is influenced by tectonic activity in the form of faults and folds.

Indonesia and Malaysia are two countries that have historically disputed with each other. One of the disputes between Indonesia and Malaysia is the Ambalat Block boundary dispute. The Ambalat Block is a sea area of ​​15,235 square kilometers which is in the Sulawesi Sea or the Makassar Strait. The Ambalat Block is estimated to contain oil and gas that can be utilized for decades to come. Ambalat, is near the border line of Indonesia and Malaysia. In this area as a fishing area in Sebatik waters. This water area is recorded to be rich with potential for reef and demersal fish. Ambalat is not only rich in fish potential. This area, which is located in North Kalimantan, has long been a dispute between Indonesia and Malaysia. One of them, because it has the potential of oil and natural gas. Geological Survey Center - Geological Agency of the Ministry of Energy and Mineral Resources (ESDM) has identified this potential. Based on G&G study data around the East Ambalat area, this potential is in the Tarakan basin and its surroundings. The naming of the marine block contained in the Ambalat block is based on the interests of exploring marine and underwater wealth, especially in the oil mining sector. Tensions between Indonesia and Malaysia are increasing due to the ownership claims of each country over the Ambalat block area, the Ambalat block area which is now a dispute between the States of Indonesia-Malaysia is not a land area but is located at a sea depth of 2500 meters on the continental shelf geographically, block Ambalat is a natural continuation of the Indonesian Kalimantan mainland which is in the Tarakan Basin spreading area which has the potential as oil and gas.

Geothermal energy is a renewable energy source that can be used to generate electricity, heat homes and businesses, and provide hot water for industrial processes. The interior of the Earth is hot, and this heat can be transferred to the surface through geological structures such as faults, fractures and sedimentary basins. These structures provide pathways for geothermal fluids to flow, and they can also trap these fluids, creating geothermal reservoirs. The type and size of geological structures that affect geothermal energy can vary depending on the location. For example, in some areas, faults and fractures are the most important structures, while in other areas, sedimentary basins are the most important. The distribution of these structures also plays a role in determining the potential for developing geothermal energy. The study of geological structure is very important to understand the distribution and potential of geothermal energy resources. By understanding how these structures influence the circulation and accumulation of geothermal fluids, we can develop and better manage these resources. This abstract provides a brief overview of the topic of geothermal energy and the role of geological structures in this field. It is intended to provide a starting point for further research and discussion.
