The risk of natural disasters in the Lembang Fault area and its surroundings will be greater in line with the increasing population growth. The high rate of population growth will directly have an impact on changes in land cover and land use in the area. One of the causes of changes in land cover and land use is the high level of human activity on land, for example infrastructure development and conversion of conservation land functions. Therefore, this study aims to predict and analyze changes in Land Use Land Cover (LULC) and their effect on the potential for increasing the disaster risk index in the Lembang Fault and surrounding areas. The resulting analysis is expected to provide information for the central government, relevant agencies, and the community in carrying out matters related to spatial planning and the use of land conversion. The research methodology used is literature study, data collection, image data processing and disaster risk map data, as well as data analysis. The classification method used is a guided classification with the CART algorithm, while the prediction of land use land cover uses the Markov chain and cellular automata methods. The results of the study showed that the built-up land had increased by 35% while water bodies, non-agricultural and agricultural experienced a decrease of 12%, 8.7%, 8.6%. Then, for vacant land, it decreased and increased by 61% and 47%, respectively. From this research, it can be concluded that the addition of the built-up area will potentially increase the disaster risk index in the Lembang Fault and its surroundings.
