“…The lowest layer is the rock layer with the highest resistivity value of 100.1 Ωm -> 274 Ωm. The resistivity value can be interpreted as a layer of limestone (Azis et al, 2023;Rahmaniah et al, 2021). Located at 74 -112 meters with a depth of 12.5 -31.9 meters.…”

The research area is located in Banga, Soppeng Regency, South Sulawesi Province. The purpose and intent of this research is to determine the resistivity value of the material layer, identify the characteristics of the slip plane and its relationship to the plasticity properties and the characteristics of the clay minerals contained in the soil. The method used to collect field data includes surface geological data and subsurface geology, which are the electrical resistivity data and surface soil data, then interpreted by combining topographiccross-sectional data and subsurface geoelectrical data along the measurement path. The first slip plane is curved as well as the second slip plane is the residual soil resulting from weathering of limestone which is still above the less dense and thick parent rock (in situ). The geochemistry of the soil samples showed that the mineral content in each layer had the largest percentage of illite 54.4% - 69.9%, and montmorillonite 6.1% - 13.6%, these two clay minerals have large shrinkage properties. Plasticity Index 29.8% - 35.8%, causing vulnerability to the soil, so that the mass movement on the sliding plane is moderate and active in slow motion. The mass movement in the slip plane can be categorized into creep type.

“…Both studies successfully identified the presence of freshwater. In South Sulawesi, similar research was conducted by Rahmaniah et al (2021), but this research is considered too regional so it needs to be done more locally, especially in the Soreang Village area, Maros Regency.…”

The seawater intrusion into the groundwater layer is one of the factors that can disrupt groundwater quality in Soreang Village, Maros Regency. This is a serious problem for the community in the area, so it is necessary to identify the seawater intrusion zone. Previous study using the resistivity method is in regional scale. In this study, two intersecting lines with a length of 470 meters each were acquired using the Wenner-Schlumberger array with a spacing of 10 meters to get local scale. Based on the resistivity value of the study area, there are three layers interpreted as a layer of fill (1 - 1000 Ωm), alluvium layer (1 - 6 Ωm) and limestone layer (≥ 7 Ωm). The seawater intrusion zone in the study area is in the alluvium layer with varying depths up to 40 meters subsurface. The results of this study can be a reference for the community or government in the search for fresh water.
