Landslides are natural disasters involving the sudden movement of a rock or soil mass. Natural disasters can affect geological, atmospheric, and anthropogenic factors. This study was conducted to reveal lineament in controlling landslides that have the potential to occur in the Kemang area and its surroundings, Cianjur Regency, West Java. Lineament is considered an essential geological structure indicator for determining general and local tectonic trends and fault zones in rocks. Lineament can also be used to assist in the analysis of probable landslides. This method uses analysis with a combination of field data and spatial data in the form of automatic extraction of Lineament and weighted overlay model methods to determine the potential landslide zone of the study area. This study used automatic lineament extraction methods and weighted overlay model methods to examine and identify lineament features of Kemang and surrounding areas. Lineament extraction of the study area showed low to high lineament density with visualisation of each azimuth. The orientation lineament consists of several directions, namely in azimuth 0o oriented Lineament West Southwest (WSW) - East Northeast (ENE), at 45o oriented Northwest (NW) - Southeast (SE), at 90o oriented North Northwest (NNW) - South Southeast (SSE), and 135o with orientation Southwest (SW) - Northeast (NE). The results of the research conducted will then be correlated with each other to provide visualization and interpretation related to potential landslides and natural disasters that have the potential to occur at the research site. The study used Five parameters: lithology, geomorphology, river flow patterns, lineage density, and slope. In overlay analysis, a new spatial data set is created by combining data from two or more input data layers. Overlay analysis combines multiple layers of datasets representing different themes to analyze or identify the relationships of each layer and produce new geometries or units. The study results provide visualization and interpretation of potential landslides in the research area. GIS is used to deal with potential landslides by analyzing the disaster. Landslide vulnerability analysis is one way to find out and mitigate landslide disaster areas in areas with high – low levels of landslide susceptibility to increase vigilance in local communities to avoid landslides.
