INTERPRETASI DATA RESISTIVITAS DI TEMPAT PEMBUANGAN SAMPAH AKHIR SUKOLILO SURABAYA

Abstract

The resistivity data in Solid Waste Final Disposal Site Sukolilo, Surabaya were measured to estimate the pattern of groundwater flow. The results of measurement were analysed by the Surfer software to obtain a map of resistivity distribution in the research site. It was estimated that there were leakage of leachate to the groundwater around the solid waste disposal site, which was identified from the pattern of minimum resistivity value among its maximum value at the coordinate (17850, 14755), (17850, 14650), (17900,14600) and (18100, 14490). By overlaying this map to the map of selfpotential data, it was obtained the maximum data was on the same location of the minimum selfpotential data. The maximum value of resistivity about 90 ohm-meter. The research concluded that the resistivity has significant correlation with the self-potential obtained from the previous research.
