Abstract

The GAR (Grand Aceh Residence) housing estate is located in Baet Village, Aceh Besar District and was constructed on the land of a pond that has been filled in and is close to the coast. The majority of residents use clean water sources from PDAM because of the difficulty of obtaining clean water. The purpose of the research was to identify potential groundwater zones and determine the conditions. The research method used was electrical resistivity method, SuperSting R8/IP with Wenner-Schlumberger configuration. The research was conducted in 3 lines with 6 m spacing. RES2DINV software based on the least square inversion approach was used for data processing. The results obtained show resistivity values varying from 0.1 - 100 Ohm.m with a depth penetration of up to 28.8m. There are 3 lithological layers obtained, namely clay (0.1 - 1.5 Ohm.m), clayey sand (1.5 - 17.7 Ohm.m), and sand (17.7 - 100 Ohm.m). The groundwater presence zone is assumed to be in the sand layer. There are 2 types of groundwater obtained, which are shallow groundwater (phreatic) located from the center to the north of the lines to a depth of ± 13 m and deep groundwater, located varies in the middle of the lines from a depth of ± 15 m to the end with groundwater conditions may still be brackish due to the influence of seawater intrusion with a resistivity value of 0.1 Ohm.m identified to a depth of ± 25 m

Abstract

This study aims to analyse the subsurface lithology in the landslide-prone area at KM-25 West Cross Road using a 2-dimensional resistivity method with a dipole-dipole configuration on two measurement tracks. The inversion results reveal significant lithological heterogeneity, with a low resistivity zone (<50 Ωm) at a depth of 5-20 metres, interpreted as a water-saturated clay layer or weathered material. The physical properties of this layer contribute to increased pore pressure, potentially forming a slip plane. The transition zone between the saturated clay layer and hard rock with high resistivity (>100 Ωm) is identified as a geomechanically weak zone prone to ground movement, primarily when saturation occurs due to heavy rainfall. The resistivity cross-section of the second pass shows similar features, with a thicker and wider zone of very low resistivity (<30 Ωm), indicating the presence of soft clays or unconsolidated fill. These results emphasise the importance of early detection of subsurface resistivity contrasts as indicators of landslide potential. This research provides an essential contribution to disaster mitigation efforts and can serve as a basis for spatial planning and infrastructure design to enhance resilience against geological hazards.
