Abstract
The area has a limestone lithology of the Rajamandala Formation and is included in the karst landscape. It has a fault zone located in the north and south of the Cipatat Area. The method used is stadio observation in the form of geological alignment, field observation to measure the direction and slope of the geological structure in the research area in the form of fractures and faults to determine the direction of the main stress. Then, an analysis was carried out using a rose diagram. The results of the study are in the form of a geological structure alignment map along with field data and its analysis. The main results obtained confirm that the geological structure of the Cipatat area is west-east which is controlled by the Karangpanganten fault, and lithological information is obtained that the research area is limestone of the Rajamandala Formation. from these data it shows that the Cipatat area is prone to landslides because it is controlled by tectonics and lithology that are less compact
