Aplikasi Geolistrik Resistivitas Konfigurasi Wenner-Schlumberger untuk Pemetaan Sebaran Leachate di Sekitar TPA Putri Cempo Surakarta Chiranjeevi Nugroho, Darsono, Ari Handono Ramelan

Abstract

Mapping leachates distribution using geoelectrical resistivity has been done at Plesungan village, Gondang Rejo, Karanganyar regency. Acquisition using Wenner-Schlumberger configuration with space of the smallest electrode is 15 meters away. This research uses resistivitymeter OYOMcOHM-EL for current injection and measure the potential difference. Inversion process uses Res2dInv software for 2 dimensions model and RockWorks16 software for 3 dimensions model. The location of the research has geology old alluvium with characteristics conglomerate, sandstone, silt and clay. Leachate mapping estimates resistivity value of <5.55 Om with the direction away from the final disposal site where the main constituent of reseach sites is clay.
