Abstract
Geothermal energy is one of the alternative energy sources that are environmentally friendly and can help meet the world's energy needs. This requires optimization of geothermal potential, one of which is the area around Mount Tampusu. This study aims to map the distribution of surface temperature around Mount Tampusu using Landsat 8 TIRS imagery and to know the difference in temperature distribution in the area around Mount Tampusu in the time period for taking data from the Landsat 8 TIRS image sensor, to determine the lateral direction of the Heat in the area. The Remote Sensing Method is an effective method used in Geothermal exploration activities through the Ilwis software. The temperature distribution is obtained from resampling the thermal band image of the Landsat 8 satellite (limiting the study area) so that the data is ready to be processed without geometric or radiometric correction processes then converted to get the surface temperature. Based on this research, it can be concluded that the temperature distribution in the area around Mount Tampusu using Landsat 8 TIRS imagery ranges from 15.2 ºC to 32.2 ºC. There was a significant change from 2016 to 2017. Meanwhile, in 2018 the temperature increased to 17 ºC from the previous year.
