Abstract

Research on identifying the subsurface layer structure and the temperaturedistribution of geothermal areas in Mantikolevillage. Dolodistrict, Sigiregency has been conducted. Measurements were performed on3 tracks around geothermal sources by using the geoelectric resistivity of wenner configuration that was subsequently processed using EarthImager2D software. Based on the results of dataprocessing, the subsurface layer structures in study area were surface water, clay, and igneous rock of granite with resistivity values ranging between 75 Ωm-1585 Ωm.Subsequently, the obtainedresistivity values were converted to a temperature distribution using anequation that is derived from Archie formula and further modelled usingRockwork software. Considering this temperature distribution, it is known that the temperature values ranged between 38oC-57oC with the highest temperature at the second track.

Keywords: Geolistrik resistivity, geothermal, temperature distribution.
