Comparison between the Measurement of SP and Resistivity Method to Detect Wastewater in the North and South Bantar Geban

The problem of waste day by day more noticeably for many people. Garbage heap from households in DKI Jakarta is the cause pollution and health problems, so the rest of the household garbage heap is collected and transported to Final Disposal (TPA) Bantar Gebang, Bekasi which far from residential areas in order to keep the environment clean. Now, in fact the problem is not only on the surface like the smell of garbage wafted until the hundreds of meters, but also below the surface. Many residents are complained that several wells have bad odor, and allegedly a result of polluted by leachate water. The garbage are mounting (open dumping) without a thick layer of skin geotextile and channel leachate container, so that oozes down the surface. Based on the study, leachate water conductivity higher than groundwater which means the resistivity value was low. Utilization of SP and resistivity method is used to review and determine the distribution of the leachate below the ground surface which already oozes to the well of residential areas.
