Penentuan Sebaran Lindi Dengan Menggunakan Metode Geolistrik Konfigurasi Wenner Dan Uji Geokimia Di Tpa Muara Fajar
ABSTRACT
The process of determining the leachate distribution at Muara Fajar Final Disposal,
Rumbai, Pekanbaru has been carried out using geoelectric methods of the Wenner
rule and the Geochemical test. This study aims to determine the distribution of the
leachate and analyze the quality of the leachate. Measurements were made on two
tracks, each track was 100 meters long. Based on the results of data processing, it is
known that the leachate distribution layer on track 1 has a depth of 2.25 – 7.46
meters below the surface with a resistivity value of 0.729 – 4.38 Ωm. The leachate
distribution layer on track 2 has a depth of 2.25 – 5.56 meters below the surface
with a resistivity value of 1.82 – 10.2 Ωm. The distribution of leachate found from
the result of interpretation is not evenly distributed on each track. The parameters of
leachate in Muara Fajar Final Disposal such as pH has a values ranging from 5.29
to 8.30 and concentration of heavy metals Cadmium has a value < 0.0031 Mg/L,
Lead < 0.0017 Mg/L. This values are still met the leachate standard parameters,
while for BOD and COD parameters in samples 1 (389 Mg/L, 2435 Mg/L) and 2
(331 Mg/L, 2069 Mg/L) were not agree with the leachate standard parameters and
in sample 3 (87 Mg/L, 135 Mg) /L) and 4 (
