IDENTIFIKASI KEBERADAAN LINDI PADA TPA MUARA FAJAR MENGGUNAKAN METODE GEOLISTRIK KONFIGURASI SCHLUMBERGER

Abstract

TPA Muara Fajar is a final waste disposal site located at Muara Fajar, Pekanbaru City which uses an open dumping system. This system still has the potential to spread leachate to the area surround the TPA because this system does not fullfil the criteria of a TPA. This study aims to identify the depth of the subsurface structure around the Muara Fajar TPA area using the Schlumberger configuration geoelectric method and determine the quality of leachate using several parameters including pH, BOD, COD, and Kadmium. The resistivity value data was processed using Microsoft Exel Software. The process was continued with inversion using Progress Software v3.0 to determine the value of the layer depth at each measurement point. The measurement result for line 1 produces the resistivity value ranging from 1015,08 – 3, 61 ohm-meters and line 2 ranging from 734,09 – 8,65 ohm-meters.
