Abstract:
The final disposal site is one of the landfill sites in the city of Pekanbaru. This final disposal
site is equipped with a leachate pond. In this area it is suspected that there is leachate
seepage which is a waste pollutant that can contaminate the soil around the final disposal
site. The final disposal of Muara Fajar is a regional waste landfill located in Muara Fajar
village, Rumbai district, Pekanbaru city which uses an open dumping system. This study aims
to determine the direction of seepage leachate around Landfill Muara Fajar using the
geoelectric resistivity method with the Wenner configuration and determining the quality of
the leachate using several parameters. The process was continued with infers using Res2dinv
Softwere.The measurement result on track 1 produces a resistivity value range ranging from
1,01 ohm meter to 32,3 ohm meter and track 2 ranging from 0,0248 to 1,13 ohm meter. To
determine the quality of leachate, 3 sample points were used, namely leachate water, river
water near the leachate disposal, and resident well water. This sample samples are tasted
with Parameters such as pH, Fe, Pb.
