Abstract

Parit Demang is an area with peatland used for residential purposes, so information on soil thickness in this area is very important for development planning. This study aims to identify peat soil thickness using the Wenner-Schlumberger configuration of the geoelectric method. Data was obtained through three measurement lines, each 50 m long. The 2D inversion modeling at the study site showed that the resistivity values of the peat layer ranged from 32.4 to 315 Ωm, with peat soil thickness between 2.3 to 5.5 m. The interpretation results were validated with soil sample drilling data. The layer located under the peat soil was identified as clay with resistivity between 1.56 to 15.2 Ωm. Information on peat soil thickness can be used as a basis for selecting soil improvement methods by the local community and related parties for development planning, particularly in the process of house construction.

Abstract

Bansir Darat is a sub-district that utilizes peatland for residential areas. Therefore, information about peatland thickness is essential for the community in the sub-district. This study aims to identify the thickness of peatland in the Bansir Darat sub-district. The geoelectric resistivity method using the Wenner-Schlumberger configuration was used in this measurement. Data collection was carried out on three tracks with a length of 50 m each and the smallest electrode spacing of 2 m. The obtained field data were inverted using the Least Squares Inversion method. The inversion results in the form of a resistivity cross-section with peatland soil estimated to have a resistivity value of 0.687 - 24.2 Ωm. The interpretation results indicate that the thickness of the peatland varies between 1.5 - 6 m. Information regarding the thickness of the peatland can be used in planning residential development by the local community.
