Abstract

PT Pertamina Geothermal Energy sudah diamanatkan pemerintah untuk melakukan pengusahaan panas bumi di Indonesia. Saat ini wilayah kerja (WK) panas bumi PT PGE yang sudah berproduksi meliputi area Kamojang, Ulubelu, Lahendong, dan Sibayak dengan total kapasitas 437 MW, sehingga menjadikan PT PGE sebagai satu-satunya perusahaan di dunia yang mengerjakan empat proyek pengembangan PLTP secara bersamaan. Guna meningkatkan pengusahaan panas bumi dan perluasan wilayah kerja salah satu cara yang dapat dilakukan adalah dengan menentukan daerah potensi panas bumi menggunakan metode Spatial Multi Criteria Analysis (SMCA). Metode Spatial Multi Criteria Analysis (SMCA) digunakan untuk menentukan model berdasarkan parameter geosains. Parameter geosains yang digunakan dalam hal ini geologi, geokimia, dan geofisika. Dengan menggunakan weighted overlay dengan bobot: 40% parameter geologi, 30% parameter geokimia, dan 30% parameter geofisika didapatkan dua kelas, yakni optimal dan cukup optimal. Luas daerah untuk daerah optimal adalah 340,446 ha, sedangkan luas daerah yang cukup optimal adalah 1568,234 ha. ========================================================= ========================================================= PT Pertamina Geothermal Energy is a Government-mandated to do the geothermal business in Indonesia. At this time, the geothermal work areas (WK) of PT PGE which already produced are Ulubelu, Kamojang, Sibayak and Lahendong, with a total capacity of 437 MW, made PT PGE as the only company in the world that was working on four projects of geothermal power plant development at the same time. In order to improved geothermal concessions and expansion of working area one way that can be done is determined areas of potential geothermal using Spatial Multi Criteria Analysis (SMCA). Spatial Multi Criteria Analysis (SMCA) is used to define a model based on the parameters of the geosciences. Geoscience parameters used in this geology, geochemistry, and geophysics. By using weighted overlay by: 40% of the geological parameters, 30% of geochemistry parameters, and 30% of geophysical parameters obtained two classes, i.e., optimal and quite optimal. The area for optimal area is 340.446 hectares, whereas a quite optimal area is 1568.234 hectares.
