Kerinci area is a small part of the Barisan Range where the Magmatic Arc Zones and a valley extending from the northwest to the southeast flanked by hills with steep slopes on both of sides that flank it. Isolated hill which is on the Kerinci Lake is the main focus to be studied because its existence is located in the middle of a part of the depression Kerinci Lake. In additions, in the vacinity of the research site there has never been research conducted both of in general and specifically. The research was conducted by interpreting the geological controlled by mechanism on isolated hill morphology forming based on geomorphoogical approach and petrographic analysis. Kerinci Lake on the south side of the research site is indicated as volcano - tectonic lake. The isolated hill is thought to be related to the formation of Kerinci Lake. In saveral location along the path of the Sumatran fault saveral lakes were found which were controlled by this fault. Sumatran fault formation is influenced by strike slip, while the formation of the lake is influenced by extensional stress. Based on it is existence, understanding the location of the research could be done analyzedg of volcanism and structural geology.

Daerah panasbumi Gunung Sumbing terletak di Desa Renah Kemumu, Kecamatan Jangkat, Kabupaten Merangin, Provinsi Jambi pada ketinggian ± 900 mdpl. Keberadaan manifestasi panasbumi di lokasi penelitian diduga belum terpetakan seluruhnya. Untuk mengidentifikasi sebaran manifestasi panasbumi dapat menggunakan Citra Landsat 8 berdasarkan sensor TIRS pada band 10. Akuisisi data geolistrik menggunakan konfigurasi dipole-dipole dilakukan sepanjang manifestasi air panas dan tanah beruap dengan panjang lintasan 750 m dan spasi elektroda 25 m. Penelitian ini bertujuan mendapatkan sebaran manifestasi panasbumi berdasarkan suhu permukaan tanah dari Citra Landsat 8 dan mendeskripsikan lapisan batuan bawah permukaan dalam menganalisis karakteristik hot springs flow berdasarkan metode geolistrik. Suhu permukaan tinggi berkisar 21-30°C berada di bagian baratdaya daerah penelitian. Hasil pengukuran geolistrik menunjukkan fluida hidrotermal dengan resistivitas 5 – 40 Ωm. Hal itu dikarenakan fluida hidrotermal berasosiasi dengan batuan alterasi sehingga bersifat konduktif. Aliran fluida hidrotermal teridentifikasi pada kedalaman 0 m hingga 25 m. Berdasarkan integrasi data geologi, faktor pengontrol adanya manifestasi mata air panas disebabkan oleh segmen Sesar Dikit dan batuan Vulkanik di daerah penelitian.Katakunci: Citra Landsat 8, metode geolistrik, panasbumi, hot springs flow.

Sumatra Island is an island that is traversed an active ring of fire at Barisan Range which is related to the active Sumatra fault system and geothermal manifestations. It is associated with geothermal manifestations in Cubadak, Talu, Bonjol, and Rimbo Panti, Pasaman Regency, and West Pasaman Regency, West Sumatra Province, as an indication of a geothermal system connected to the Sumatra Fault System from the Sianok Segment and the Talamau Volcano Complex. Sustainable geotourism has become effective for sustainable development of geotourism, the geothermal energy direct utilization. The purpose of this study is to provide sustainable geotourism from geothermal potential in the fault system, taking into account aspects of village geotourism, ecotourism, ecoculture, and education. The methodology used in this study is to collect data on geothermal manifestations from regional geological maps and field observations in geothermal manifestation areas by considering sustainable geotourism. A simple model of sustainable geotourism is made. Study results indicate several locations of potential geothermal manifestations to be used as sustainable geotourism associated with the Sumatra Fault System and the Talamau Volcano Complex.
