Located in West Lombok, Gunung Sari is an area that frequently experiences landslides. Diverse land characteristics and the incompatibility of land allotment allegedly can be some factors causing the landslides. Therefore, it is necessary to conduct research to analyze the land suitability in some areas with a high frequency of landslides. The research approach used in this research is descriptive quantitative with overlay analysis techniques using Arc Gis application program. Based on the data analysis results, it was discovered that Gunung Sari has an area of 2.376.36 Ha or 29% of the total land area which is not in accordance with its designation, an area of 4.032.49 Ha or 49% of the total land area can be categorized into a conditional land and an area of 1.786 Ha or 22% of the total land might be classified into a suitable area land. According to the land function of this area, it was found that the largest area that is unsuitable land and conditional land are located in the conservation zone covering an area of 2249.48 Ha for the unsuitable land and 2433.24 Ha for the conditional land.
