Study area is located in Kertasari Area, Brebes District, Central Java. It covers 17,5 km2 of total area located on Ketanggungan dan Banjarharjo Subdistrict, while methods use in the geological mapping are field observation and laboratory analysis and methods use for land use application is Analytical Hierarchy Process with Geographical Information System (GIS) as tools to process data. Lithostratigraphic units of the study area from older to younger are Sandstone-Siltstone Unit (equalized with Halang Formation), Volcanic Breccia Unit (equalized with Kumbang Formation), Claystone Unit (equalized with Kalibiuk Formation). These units are deposited conformably one to another,and they overlain unconformably with Alluvial Deposit Unit. Geomorphology units are divided as follows: Synclinal Valley Unit, Synclinal Ridge Unit, Denudational Plain Unit, and Aluvial Plain Unit. Main stress in the study area is northeast-southwest. Geological structure developed in the study area are synclinal fold, thrust fault, and strike-slip. The study area is at mature geomorphological stage. Recommendation zones are divided as follows: Very Feasible Zone (40%) in northern and eastern area, very feasible for settlement area. Feasible Zone (30%) in outer-middle and southwestern area, fesible for settlement area. Fair Zone (25%) in semiouter-middle and northwestern area, not feasible for settlement area, more feasible for plantation area. Poor Zone (5%) in middle area, not feasible for settlement area, more feasible for conservation forestry zone.
