Abstract

This study aims to examine the geothermal manifestations in the Dieng Plateau using remote sensing methods and provide recommendations for their potential utilization as geothermal resources. The main research questions addressed are the condition of geothermal manifestations in this region based on remote sensing methods and the recommendations for their utilization based on temperature classification from data processing results. The objective of this study is to analyze the condition of geothermal manifestations in the Dieng Plateau and to provide recommendations for their potential use as geothermal resources based on temperature classifications. The research methods involve processing Landsat 8 satellite imagery data and conducting field surveys. The imagery data is processed to obtain land surface temperature (LST) classifications using the Radiative Transfer Equation (RTE) developed by Prof. Jose Antonio Sobrino. The processing steps include image cropping, radiometric correction, converting radiance to brightness temperature, NDVI, vegetation proportion, land surface emissivity, and land surface temperature. Field surveys are conducted to validate the image processing results. Data analysis includes surface temperature analysis, image interpretation, field validation, and result comparison. The results show that the maximum surface temperature at Kawah Sileri and the industrial area reaches 31.03˚C, while the minimum temperature in the forest area is 13.31˚C. Temperature classification in various research locations shows low to very low temperatures, with the highest temperature at Kawah Sileri and the lowest at Mata Air Sipandu. This temperature variation is influenced by the area size, where smaller areas utilized as hot spring baths tend to have lower temperatures compared to larger, unused manifestations. Data processing results indicate that the surface temperature in the study sites does not meet the criteria for geothermal energy sources, which require a minimum temperature of 180˚C-250˚C. The correlation analysis between LST and NDVI shows a decreasing trend, where higher surface temperatures correlate with lower vegetation density. This is evidenced by the conditions in geothermal manifestation areas, which have sparse vegetation due to the soil and rock structure being unsuitable for plant growth. This study concludes that although there are geothermal manifestations in the Dieng Plateau, the surface temperatures do not meet the criteria for geothermal energy sources. The correlation between surface temperature and vegetation density provides additional insights into the environmental conditions around the geothermal manifestations.
