“…In addition, the geological structure in the form of lithology, layers of rock formations for each layer, alteration structures and sources have not been thoroughly discussed. The use of the MT method in previous studies [9] also did not provide good resolution in the shallow subsurface structure layer. Therefore, to obtain maps and 3D geological structure models in the geothermal prospect area in Kepahiang as a whole, this research was developed using the geomagnetic method.…”

“…Geologically, the Kepahiang geothermal field is part of the complex Kaba volcanic system [4][5][6], [9], [17]. Kaba Volcano consists of the main parts, namely the remnants of the Old Kaba and Young Kaba eruptions which are located around the remnants of other volcanic eruptions such as Malitan Hill (located southeast), Lumut Hill (northwestern part), and Taba Penanjung (southwestern part).…”

“…Therefore, to obtain maps and 3D geological structure models in the geothermal prospect area in Kepahiang as a whole, this research was developed using the geomagnetic method. The application of this method is based on the value and distribution of subsurface rock susceptibility which is closely related to the structure and geothermal system [9]- [14] in Kepahiang. The magnetic method is a very effective and efficient application for geothermal exploration because it can determine geothermal prospects by looking at the horizontal and vertical distribution based on rock susceptibility values [9], [11], [12], [14][15][16].…”

The magnetic method is a very effective and efficient application for geothermal exploration because it can determine geothermal prospects by looking at the horizontal and vertical distribution based on rock susceptibility values [9], [11], [12], [14][15][16]. The specific objectives of this study were (1) to map the magnetic anomalies of the geothermal field in Kepahiang, (2) to determine the lithology and rock formations of each layer to the maximum depth obtained from measurements based on rock susceptibility values, (3) the geological structure and its distribution on the administrative map of Kepahiang and its relationship to the activity of Mount Kaba and the Sumatran fault, and (4) the zone of altered rock distribution.…”

Deliniasi 3D struktur geologi daerah prospek Geothermal di Kabupaten Kepahiang telah dilakukan. Tujuan Penelitian adalah untuk mendapatkan gambaran subsurface dan geothermal system di Kepahiang serta memetakan zona alterasinya. Pemodelan kedepan dan inversi dilakukan kepada 194 data geomagnetik telah diukur menggunakan Proton Precission Magnetometer. Hasil analisi mendapati bahwa prospek lapangan geothermal di Kepahiang terdistribusi di Babakan Bogor, Barat Wetan, Pematang Donok, Tangsi Duren, Sido Makmur, dan Air Sempiang dengan kedalaman rata-rata reservoir 900 m dengan jenis batuan lapisan penudung yaitu gabro (ketebalan rata-rata 1100 m). Empat jenis formasi batuan ditemukan diantaranya batuan breksi gunung api, batuan basal, batuan gabro, dan batuan teralterasi. Anomali rendah yang berada di Babakan Bogor, Barat Wetan, Kuto Rejo, Pematang Donok, Tangsi Baru, Sido Makmur dan Air Sempiang diduga disebabkan oleh Sesar Segmen Musi yang masih aktif dan termagnetisasi secara induktif akibat reservoir panas bumi dari aktifitas Gunung Kaba

Conservation areas are synonymous with protected areas and is prohibited for social and industrial activities that damage the environment. How ever, this research found in which at Bukit Kaba, the use of conservation areas could support the preservation of the natural environment. This article explained that by finding niche commodities, conservation areas can generate many economic benefits for the surrounding community and preserve the natural environment at the same time. This research was environmental qualitative research conducted at conservation area of the Bukit Kaba, Bengkulu, Indonesia. Data were obtained through observation, interviews, document studies, and focus group discussion with the Bukit Kaba conservation area stakeholders. The research team stayed for 20 days in Rejang Lebong district and visited community groups while conducting observations and interviews. The research concluded that the agreement between farmer groups and the Balai Konservasi Sumber Daya Alam (Nature Conservation Agency) to maintain and cultivate sugar palm trees at Bukit Kaba conservation area is an excellent green economic practice. The agreement stipulated the palm trees growing in the Bukit Kaba conservation area as a niche commodity because it can provide multiple benefits. On the one hand, palm trees provide economic benefits to residents around the conservation area. On the other hand, palm trees help maintain land and soil resilience in the Bukit Kaba area.
