Abstract:
The landfills (TPA) Cahaya Kencana is applying system Sanitary Landfill, the landfill system
that is done by the garbage dumped and compacted, then covered with dirt as cover and carried out
continuously each end of the operation. This research is very important investigate the distribution of
leachate contaminated leachate approximately systems Sanitary Landfill based on the resistivity value and
the content of chemical elements in the holding pond. Based on the results of data processing 2D geoelectric
Wenner configuration on four tracks with each track length of 100 m were processed using Res2dinv,
obtainable at a depth of between 0.75 – 11.6 m resistivity values in the leachate is 4.34 – 10.0 Ωm track 2, 3,
and 4, but are not on track 1. The results of laboratory test on four samples consecutive for content. BOD
leachate from 26.2 - 121.0 mg/l; and COD 132.5 – 276.2 mg/l is not exceeded the limit of waste water quality
standard, except for sample 4 with a COD value of 472.9 mg/l while for pH 7.24 - 7.39 mg/l and the
concentration of heavy metals in leachate outlet still on the threshold of normal, where Pb <0.0019 mg/l; Cd
<0.0019 mg/l; and Cr <0,0035mg/l.
