Abstract:
Research to find out the identification of subsurface layer of muara fajar landfill
using geoelectric method of Sclumberger configuration Rumbai subdistrict,
Pekanbaru City.has been done. The method used in this study is one-dimensional
Schlumberger configuration geoelectric method. Data were processed using
Software called Progress. Based on the results of data processing then the
information on rock layers at the research site is obtained. The results of the data
processing showed on the track 1 that the resistivity values of the soil layer are
976.43 ohm-meters at a depth of 0 - 8.39 meters, 116.69 ohm-meters at a depth of
8.39 - 20.15 meters, 151.55 ohm-meters at a depth of 20.15 – 42.65 meters, 69.12
ohms-meters at a depth of 42.65 – 55.04 meters, 4.20 ohms-meters at a depth of
55.04 meters. The track 2 soil layer resistivity values, are 896.61 ohms-meters at a
depth of 0 – 4.16 meters , 1709.36 ohms-meters at a depth of 4.16 – 9.86 meters,
361.98 ohms-meters at depths of 9.86 – 24.96 meters, 565.60 ohms-meters at
depths of 24.96 – 44.15 meters, 45.96 ohms-meters at a depth of 44.15 meters.
Based on the depth of track 1, the information obtained consists sand and gravel
with a thickness of 8.39 meters, sand with a thickness of 11.76 meters, sand with a
thickness of 22.5 meters, a layer of aquifers with a thickness of 12.39 meters and
lindi water obtained at a depth of 55.04 meters while for track 2 consists sand and
gravel with a thickness of 4.16 meters, sand with a thickness of 5.64 meters ,
gravel with a thickness of 15.09 meters, sand with a thickness of 10.67 meters and
aquifer layer obtained at a depth of 44.15 meters, while for the lindi water layer is
only identified on track 1 at a depth of 55.04 meters.
