Abstract
The DC resistivity method is a subsurface investigation method that can identify subsurface temple structures without excavation. This research aims to obtain the subsurface structure at Serut Temple in Batujaya Temple Area, Karawang, West Java, using geoelectric method.The DC resistivity measuring instrument used in this research is Marcapada with 48 electrodes and 0.5 m spacing between electrodes. The Wenner configuration geoelectric method was used to identify the subsurface layer and the buried temple structure in the study area. Measurements were made on 9 passes with a track length of 23.5 m. The results showed a resistivity value range of 6 Ω-m - 17.9 Ω-m which is suspected to be a temple structure. Then for resistivity 3 Ω-m - 6 Ω-m as sandy loam, and resistivity1 Ω-m - 3 Ω-m is thought to be a layer with high water content. The estimated depth of the temple structure is 1 m - 3.21 m. The 3D reconstruction results show that the alleged structures on the L3, L4, and L5 trajectories have a continuous projection from northwest to southeast. This is in accordance with the Batujaya National Cultural Area Zoning Report by the Director General of Culture that the Batujaya Temple building faces northeast. Based on this finding, it is possible that the temple structure is part of the wall of the temple building, this wall is a continuation of the Serut Temple structure.
