Abstrak

Indonesia has significant geothermal energy potential associated with its active volcanic and tectonic setting. The Lumut Balai area in Muara Enim Regency, South Sumatra, is a prospective geothermal area characterized by surface manifestations and geological structures that may control hydrothermal fluid circulation. This study aims to identify indications of geothermal potential in the Bukit Lumut Balai area using remote sensing and spatial data interpretation. Landsat 8 OLI and Digital Elevation Model (DEM) data were analyzed to derive several parameters, including Normalized Difference Vegetation Index (NDVI), Land Surface Temperature (LST), slope, lineament, Fault Fracture Density (FFD), and surface hydrothermal alteration. The parameters were interpreted spatially to identify areas associated with geothermal manifestations and geological structures. The results indicate that geological structures strongly control the Lumut Balai area, particularly lineaments with a dominant NW–SE orientation consistent with Sumatra's regional structural pattern. Areas with high FFD values are interpreted as potential permeable zones that may facilitate hydrothermal fluid circulation. LST analysis identifies surface temperature anomalies, with values reaching approximately 70°C, while areas with high surface temperature generally show lower NDVI values. The alteration map also indicates hydrothermally altered zones associated with structural features. These results, together with the occurrence of hot springs, indicate that the Bukit Lumut Balai area has geothermal potential and that remote sensing can be used effectively as an initial reconnaissance tool to identify prospective geothermal zones.
