Abstract

The subsurface structure of the geothermal field in Desa Tambang Sawah has been mapped. This research aims to delineate the resistivity values in the area of Tambang Sawah Village, Lebong Regency, Bengkulu Province based on magnetotelluric measurements which can later identify low, medium, and high resistivity values to interpret geothermal in the research area. The magnetotelluric (MT) method with electrical and magnetic sensors is used to collect data in the field. There are two electrical sensors in horizontal direction (Ex, Ey) and three magnetic sensors in horizontal direction. (Hx, Hy) and vertical (Hz). The results obtained from this study are that resistivity values of 20-50 ohm.m are considered as reservoirs, while resistivity of 0.26-0.8 ohm.m is considered as caprock, and resistivity greater than 300 ohm.m is considered as hot rock.

Abstract

Kepahiang Regency, Bengkulu Province, is an area crossed by the Musi segment of the Sumatra Fault and a number of secondary faults, including the Bogor Fault, which contribute to the high level of seismic activity in the region. The presence of these active faults, combined with a relatively high population density, poses a potential threat to infrastructure and public safety. This study aims to identify the subsurface geometric characteristics of the Bogor Fault, particularly its upper and lower depths, as part of earthquake disaster mitigation efforts. The Magnetotelluric (MT) method was used in this survey with the ADU-07e system, which utilizes natural electromagnetic fields, with two horizontal electrical sensors (Ex, Ey) and three horizontal sensors (Hx, Hy), as well as a vertical magnetic sensor (Hz). Data collection was conducted at six measurement points with a 1 km interval along the Northeast–Southwest transect that crosses the Musi Fault and the Bogor Fault. Data processing was performed using MAPROS software for time-domain to frequency-domain conversion, and ZONDMT2D for subsurface modeling. The modeling results showed a low resistivity zone at point T6, with values between 0.21–1.6 Ωm, which was interpreted as the presence of the Bogor Fault. This zone was identified at a depth of approximately 2 km and was estimated to extend more than 8 km in the north–south direction. This finding provides important indications of the presence of an active fault in the area and can serve as a basis for earthquake risk mitigation efforts in Kepahiang.

Abstract

Penyelenggaraan pemerintahan daerah di Provinsi Papua Barat Daya, sebagai daerah otonom baru, menghadapi berbagai tantangan, antara lain keterbatasan kapasitas kelembagaan, rendahnya transparansi dan akuntabilitas, serta partisipasi publik yang belum optimal dalam proses pengambilan kebijakan. Kondisi-kondisi tersebut menjadikan penerapan prinsip-prinsip tata kelola pemerintahan yang baik (good governance) sebagai kebutuhan mendesak demi mewujudkan tata kelola pemerintahan yang efektif, bersih, dan responsif terhadap kebutuhan masyarakat setempat. Urgensi penelitian ini terletak pada pentingnya penyediaan landasan empiris dan rekomendasi kebijakan yang relevan dengan konteks sosial, budaya, dan kelembagaan Papua Barat Daya. Tujuan penelitian ini adalah untuk menganalisis penerapan prinsip-prinsip tata kelola pemerintahan yang baik—meliputi transparansi, akuntabilitas, partisipasi, efektivitas, efisiensi, dan supremasi hukum—dalam penyelenggaraan pemerintahan daerah di Papua Barat Daya; mengidentifikasi faktor pendukung dan penghambat; serta merumuskan strategi penguatan tata kelola pemerintahan daerah yang berkelanjutan. Metode penelitian yang digunakan adalah pendekatan kualitatif dengan desain studi kasus. Pengumpulan data dilakukan melalui wawancara mendalam dengan para pemangku kepentingan utama, observasi lapangan, serta analisis terhadap dokumen kebijakan dan regulasi daerah. Analisis data dilakukan secara deskriptif dan analitis dengan menggunakan teknik triangulasi untuk menjamin validitas dan reliabilitas temuan penelitian. Luaran yang ditargetkan dari penelitian ini meliputi publikasi artikel ilmiah pada jurnal nasional terakreditasi, rekomendasi kebijakan bagi pemerintah daerah Papua Barat Daya, serta model penerapan tata kelola pemerintahan yang baik yang bersifat kontekstual dan praktis sebagai acuan untuk meningkatkan kualitas penyelenggaraan pemerintahan daerah.
