Distribution Analysis of Leachate Using the Wenner Configuration Resistivity Method at Sambutan Tpa, Samarinda City, East Kalimantan, Indonesia

Abstract

The research located in Sambutan TPA, Samarinda City, East Kalimantan Province, Indonesia, with an area of ​​± 350 m2. This study aims to interpret the resistivity and direction of the distribution of subsurface leachate using the resistivity method of the Wenner configuration with a track length of 90 meters per pass. The leachate is known to have a resistivity value of < 10 Ώm. The results of the analysis of the measurement location and the indicated depth of leachate have different variations, on the path 1 leachate in the north - south direction has a resistivity value range of 0.467 - 8.76 Ώm with a depth of 0 - 12.4 m, path 2 leachate with the direction of Northeast – Southwest has a resistivity value range of 5.77 Ώm with a depth of 0 – 12.4 m, path 3 leachate in a South – Northwest direction has a resistivity value range of 2.55 – 9.34 Ώm with a depth of 0 – 15 m and track 4 of leachate in the Southwest – Northeast direction has a value range of 6.49 – 8.78 Ώm with a depth of 0 – 7.82 m. The results of the interpretation of the geoelectric trajectory have the direction of the leachate distribution in the Northeast – Southwest direction in the study area.
