Daerah Pasirwangi merupakan salah satu area terdampak signifikan ketika terjadi gempa bumi akibat aktivitas Sesar Garsela. Kerusakan akibat gempa ini semakin parah akibat litologi penyusun daerah ini merupakan endapan gunungapi muda yang bersifat lepas dan belum terkonsolidasi. Oleh karena itu, penelitian mengenai besaran deformasi permukaan yang diakibatkan oleh sesar aktif ini diperlukan untu…
Daerah penelitian terletak di Desa Cimanintin dan Sekitarnya, Kabupaten Majalengka, Provinsi Jawa Barat. Penelitian ini dilakukan dengan menggunakan data primer dan data sekunder. Data primer berupa pengamatan singkapan dan observasi lapangan terhadap enam titik sampel pada lokasi penelitian yang kemudian diambil sampel batuan untuk dilakukan analisis petrografi. Sedangkan data sekunder berasal…
Landscape along the deformation zone in an area of 81 km2 in the Citarum area, Cianjur Regency has been identified by two approaches, namely reconstructing the geological structure cross-section and analyzing topographic 3D expressions with Digital Elevation Model (DEM). Determination of the boundary of the structural zone is undertaken by interpreting the five geological sections, which are co…
The mining process in Bangko Tengah entered the initial staging of production processing. However, on the low wall of the excavation, there is still coal that has yet to be produced due to the influence of landslide material on it and limited land for excavation. Therefore, studies on geomechanical models are required to find low-wall weak-layer areas. Material properties that are the focus of …
Sumatra is one of the islands in Indonesia that is affected by active tectonic activities, because it is controlled by the interaction between the Indo-Australian and Eurasian plates. The interaction between the two lithospheric plates resulted in the emergence of the Barisan Orogeny, where the basin area was uplifted and active faults were developed along the island. This study examines the ro…
Identification of geological structures using the Global Gravity Model Plus (GGMPlus) gravity model by taking the area of Keban Jati and its surroundings, South Bengkulu, Bengkulu. The aim of this research is to identify subsurface geological structures and to understand the relationship between field structure data. The analysis method involves field geological information and previous studies…
The research area is in the Pseksu Sub-district and its surroundings, including the South Sumatra Basin with active tectonic influences. This study intends to identify the tectonic activity level by using a quantitative geomorphological approach (morphometry) conducted in the Kikim sub-watershed. The research area is divided into 3 (three) segments, namely segment one on the Sungai Saling, segm…
Research on the geochemistry and petrogenesis of granitoid rocks that make up Granite Garba (Kgr) was conducted in Biabia, Muaradua District, South OKU, South Sumatra. Granit Garba is one of the basements that make up the Garba Mountains which was exposed due to uplift in the Paleogene. The research was conducted using two approaches, namely petrographic analysis and rock geochemistry. Petrogra…
Identifikasi morfologi dan struktur geologi berdasarkan lineament dilakukan di dalam dan sekitar Desa Tanjung Beringin, Kabupaten Lahat, Sumatera Selatan. Tahap awal identifikasi menggunakan pendekatan penginderaan jauh dengan analisis lineament menggunakan data DEMNAS. Penelitian ini berfokus pada analisis lineament menggunakan data Digital Elevation Model (DEM) untuk mengidentifikasi struktur…
Meteorology, Climatology, and Geophysics Agency (BMKG), earthquake activity has increased significantly in Indonesia. Given the new planning standards, it is important to know the extent of the difference in response range from the SNI standard 1726-2012, and how this affects the earthquake load for building structures built in accordance with SNI 1726-2012. So the research was conducted by ana…
