The geotechnical condition of an area is very decisive in choosing the location of a dam to be built because it affects the stability and seepage of a dam. The Randugunting Dam is a dam that will be built in the Blora area, Central Java, so it is necessary to study the geotechnical feasibility around the planned dam. The purpose of this study was to determine the geological conditions and geotechnical aspects of the area planned for the construction of the Randugunting Dam. The method used in this study is to conduct surface analysis (mapping) and subsurface analysis (drilling) on the planned location of the dams. The morphological conditions of the planned dam area and its surroundings are corrugated hilly areas that have a river width of around 10-20 m, with steep cliff morphology on the right side and a relatively sloping left side. Lithology in the study location can be grouped into three rock units, namely topsoil (gravel, gravel sand, silt, and clay), Calcareous Siltstone units (Ledok Formation) and Calcareous Claystone units. The foundation of the dam will be above the bedrock which is composed of calcareous siltstone from the Ledok formation which is classified as varying into rock class (D), (D - CL) and (CL - CM). Permeability in dam foundations generally has a lugeon Lu value of < 3, so that the foundation is quite impermeable and there is no need for treatment using the grouting method.
