Abstract

Penelitian mengenai identifikasi sesar di Kabupaten Sumbawa bagian selatan ini dilakukan dengan menggunakan metode gravitasi. Penelitian Data yang digunakan berupa data Free Air Anomaly (FAA) dan Topografi yang merupakan data citra saletit TOPEX. Data tersebut dilakukan koreksi Bouguer dan Terrain untuk diperoleh data anomali bouguer lengkap. Nilai Anomali bouguer lengkap dilakukan pemisahan anomali regional dan anomali residual dengan menggunakan filter Gaussian. Anomali regional memiliki rentang nilai 115.0 mGal sampai 164.2 mGal sedangkan anomali residual memiliki rentang nilai -8.8 mGal sampai dengan 6.8 mGal. Pada Anomali residual menunjukkan zona anomali rendah pada zona selatan bagian tengah yang dipengaruhi oleh densitas batuan di zona tersebut yang berupa alluvial dan endapan pantai. Anomali residual yang dihasilkan dilakukan analisis second vertical derivative (SVD) untuk mengidentifikasi jenis sesar/patahan di wilayah tersebut. Berdasarkan interpretasi, zona sesar/patahan berada pada nilai anomali rendah yang diapit oleh nilai anomali tinggi sehingga patahan yang berada di bagian selatan daerah penelitian relatif berarah Timurlaut-Baratdaya. Grafik hasil slicing menunjukkan nilai maksimum lebih kecil dibandingkan mutlak nilai minimum sehingga disimpulkan bahwa sesar di kawasan tersebut merupakan sesar naik.

Abstract

The research area is in the Datae Area, Watangpulu District, Sidenreng Rappang Regency, South Sulawesi Province. This study aims to determine the distribution of volcanic rocks, determine the crystallization phase based on petrographic analysis, and determine the type, magma affinity and tectonic environment based on geochemical data. The method used in this study was field data collection and rock sampling for analysis through petrographic analysis and geochemical analysis using the X-Ray Fluorescence (XRF) method by analysing the main elements, trace elements and rare earth elements (REE). The results of the petrographic analysis show that the rocks found in the field are volcanic breccia and ignimbrite. Volcanic breccia showed coarse-grained texture composed of angular to rounded andesite fragments and pyroclastic material fused together in a matrix. Meanwhile, ignimbrite showed fine grained texture with lapilli to boulder-sized fragments, poor sorting, open-packed and non-layered structure. Based on the Total Alkali Silika (TAS) diagram, AFM diagram, and binary diagram, the results of the geochemical analysis showed that the rocks found in the study area were andesite and trachy-andesite, while the magma affinity area is high-K calc-alkaline and shoshonitic. High-K calc-alkaline magmas are associated with subduction zones and are characterized by elevated levels of potassium and aluminum, while shoshonitic magmas are typically found in intraplate or back-arc settings, characterized by their distinctive potassium, sodium, and barium-rich compositions. The results from ternary diagram and geochemical Spider plots proved that the magma tectonic environment is island arc—continental arc basalt, indicating that the rock was formed in a subduction area. This research supports previous research regarding the tectonics of the western arm of Sulawesi, which stated that this area was formed by subduction.

Abstract

The aim of this study is to create a descriptive model of environment-based reclamation recommendations for ex-mining land in the Sumbawa region that is easy to understand and consider. This research consisted of three stages: literature studies from previous researchers were used as a basic reference to strengthen the background and discussion in the research, especially with regard to environment-based reclamation engineering, mapping of open hole points from former community mining, and environment-based reclamation recommendation models. well and precisely in the corn plantation while still considering the initial shape of the topography. Effective reclamation to restore agricultural land damaged and with holes caused by mining without permits by providing recommendations in the form of a descriptive model includes backfilling of openings, planting trees, or revegetation, considering it for agrotourism, and economical fish-farming ponds.

Abstract

income for the local community, also have negative impacts, namely land degradation with numerous abandoned and poorly managed former mining holes. This research aims to provide practical and sustainable recommendations for adaptive reclamation activities in former artisanal mining areas in Area Y, and to serve as a guide for realizing more responsible and sustainable artisanal mining practices. The research was conducted using a qualitative method through the analysis of relevant secondary data. The study results indicate that miners tend to leave former mining holes unreclaimed. This is due to miners' limitations in both technical knowledge and capital, rendering them incapable of carrying out reclamation independently. The impact of these abandoned mining holes has the potential to become a future hazard. The selection of an adaptive land reclamation model focusing on a flexible and participatory approach has proven to be an effective and efficient method for implementing reclamation activities in artisanal mining. Both government and non-governmental agencies can conduct intensive education and training to maximize local community participation for the success of reclamation activities

Abstract

Kegiatan  pertambangan  mangan  di  PT  Ngali  Sumbawa  Mining  (PT  NSM),  merupakan perusahaan swasta nasional yang memiliki Izin Usaha Pertambangan (IUP) sejak tahun 2011 yang berlokasi di Desa Lape, Kecamatan Lape, Nusa Tenggara Barat. Kegiatan pertambangan terbuka oleh PT. Ngali Sumbawa Mining berpotensi menimbulkan perubahan kondisi lingkungan, terutama pada kestabilan lereng dan kualitas air permukaan di sekitar wilayah tambang. Maka, tujuan penelitian ini adalah untuk menilai potensi bahaya lingkungan akibat aktivitas penambangan mangan. Evaluasi terhadap risiko longsor ke arah Dusun Ngali serta kemungkinan pencemaran air menjadi langkah awal untuk memastikan kegiatan penambangan tetap sesuai dengan prinsip pertambangan berkelanjutan (sustainable mining). Penelitian dilakukan secara deskriptif dengan metode kuantitatif, melalui studi literatur, observasi lapangan serta pengujian laboratorium. Hasil penelitian menunjukkan, kondisi lereng pada area penambanga PT Ngali Sumbawa Mining stabil, sehingga potensi kelongsoran kecil. Sedangkan, untuk kualitas air dari aktivitas penambangan masih berada dalam rentan baku mutu yang ditetapkan oleh pemerintah
