The determination of geothermal potential area based on remote sensing, Micromine software, and land surface temperature calculation

Abstract

Indonesia has a significant geothermal energy potential because it is in the Ring of Fire. However, only 7% of identified potential geothermal has been utilized until now. This research aims to determine and predict geothermal potential area by using Landsat 8 imagery, Micromine software, and Land Surface Temperature Calculation. Land Surface Temperature calculation can be carried out by thermal infrared bands which can be obtained from Landsat 8 imagery. Land Surface Temperature calculation is based on a Split-Window algorithm which providing a surface temperature value and its distribution. Furthermore, the method can support to generate the distribution of Land Surface Temperature in research area using Micromine software. The remote sensing analysis also being done to determine geological structures development in the research area which assumed to control manifestation occurrence. It also shows the appearances of geothermal surface manifestation. The result of Land Surface Temperature analyses could predict surface temperature zone in the research area. The area that has high surface temperature value tends to be an area that has a potential geothermal area. The application of this method is being done on a potential geothermal field around Mt. Patuha, Ciwidey, West Java to verify these approaches. This research shows that Land Surface Temperature method to determine geothermal potential has a positive result.
