Abstract
The laundry business on Taman Karya Street produces the disposal of waste
containing chemicals surrounding the ground water in that place. This research
aims to determine the depth of groundwater, investigating the water quality for
consumption using the Schlumberger configuration geoelectric method on two
tracks with a length of 100 m. The data obtained in the acquisition process is used
to calculate the apparent resistivity value at each measurement point and analyzed
quantitatively and qualitatively. The process is continued with inversion using the
Software Progress v3.0 application so that the resistivity and layer thickness
values can be obtained. The result show that the first track obtains a range of
resistivity values ranging from 198.58 Ωm to 252.61 Ωm, and the second track is
9.90 Ωm to 1209.97 Ωm. There are five sample points from each of the laundry
wells and residents' wells. The underground water sample is tested such as pH,
TDS, conductivity, salinity, and turbidity. The results show that the underground
water around the research area cannot be consumed by the people who live in that
area, based on the Regulation of the Minister of Health of the Republic of
Indonesia. The data describe that underground water samples exceed the standard
quality in which the pH is 6.5 or acidic. However the TDS and turbidity
parameters still fulfill with the quality standard.
