Abstract



Research related to the identification of slip surfaces was conducted on the Trans Seram Road section in the Sugiarto area, Kariele Hamlet, Haruru Village, Amahai District, Central Maluku Regency. This area is fairly steep and hilly, so landslides often occur. This can disrupt activities and endanger the community, as the area hosts several community settlements and serves as an important route for commodity distribution in the Central Maluku region. This research aimed to assess landslide potential by identifying the slip surface using the ERT (Electrical Resistivity Tomography) method. ERT measurements were carried out using the Wenner-Schlumberger configuration at four locations within a narrow area adjacent to a relatively deep ravine. At each location, one survey line was established parallel to the road, spanning 200 meters and with an electrode spacing of 5 meters. The results of the measurements and data processing revealed indications of slip surfaces at each location, with varying depths reaching up to 18 meters. To achieve optimal results, it is necessary to validate drilling data on rock layers below the surface and to conduct further geotechnical research . In addition, the results of the research are expected to have a positive impact on the community and local government in designing future policies related to regional development and can serve as a reference to encourage further research.
