Urbanization attracts people migration, which in turn triggers land use change. Bekasi Regency has a role as a food security area, but the increasing trend of builtup land threatens the existence of the food provision ecosystem. Planning has an important role in creating a livable and sustainable region into the future. Environmental carrying capacity in the form of food provision ecosystem services is an important indicator to be considered in planning. Measuring the Index of Ecosystem Services (IJE) of food producer lands is one of the alternatives to map the food provision ecosystem services. Before irreparable damage to food provision ecosystems, it is necessary to understand the condition of food availability in the future through land cover change prediction models and their influence on food provision ecosystem services as a consideration in spatial planning. The purpose of this study is to conduct spatial modeling of land cover change and its influence on food provisioning ecosystem services as a consideration in spatial planning in Bekasi Regency. In this study, secoandary data used are from the government and other official websites. The findings of this study include classifying land cover in Bekasi Regency into 10 classification, whose changes generally come from nonbuilt land to built-up land. Prediction models were conducted with and without constraint zones, both of which resulted in an increasing trend of land cover change to built-up land until 2031. As a result, in the IJE mapping of food providers, low category IJE values will increasingly dominate in the future. There is an incompatibility between the prediction results and the prevailing spatial policy, such as RTRW and LSD. Efforts are needed to further optimize the availability of area for food provision ecosystem, including through increasing the policy enforcement in the application of spatial regulations, improving the determination of food security priority areas, and synchronizing between spatial policies.
