Interpretasi Potensi Air Tanah Dan Parameter Fisis Bawah Permukaan Bumi Di Kecamatan Bukit Raya
Research has been done in the area of Bukit Raya Subdistrict which aims to
determine the potential for groundwater and underground lithology, determine the
permeability of the soil layer, and determine the quality of well water and trench
water around the research trajectory. The method used in this research is the
geoelectric resistivity method of the Wenner Configuration by taking 2 lines of data
and each track is 100 meters apart. Data processing used non-linear least square
optimization method with 2D inversion in Res2Dinv software. Lithology of track 1
with a resistivity value of (49.6-672) Ωm in the form of clay, sand, gravel, gravel and
sandstone and lithology of track 2 with a resistivity value of (41.0-3.896) Ωm in the
form of clay, sandy loam , sand, gravel, bedrock filled with dry soil, and lumps of
scale and sandstone. The water found is surface infiltration water with a resistivity
value of (0.5-300) Ωm. Soil permeability was measured in the study area as many as
10 samples using GPS and processed in the soil laboratory. The maximum soil
permeability value for 10 soil samples was 5.69 cm / hour and the minimum
permeability value was 0.33 cm / hour. Well water samples taken were community
well water in the study area as many as 4 samples and 6 samples of trench water. The
well water and trench water samples will be tested with pH and turbidity parameters.
One sample of well water is acidic with a pH value of 6.19 in Tengkerang Utara
Village. The well water and ditch water turbidity parameters have a value in
accordance with the quality standard, which is below 25 NTU.
