The successful determination of buffer zone played the main role in the implementation of sustainable development in the National Parks. However, the buffer zone of Sembilang National Park (SNP) in Banyuasin Regency, South Sumatera, Indonesia was not well proposed due to the complex conflict of interest and the fragmentation area. The present study aims to propose the most appropriate criteria in determining the SNP buffer zone using the overlay technique between the ecological and socio-economic aspects. The analysis was conducted using Quantum Geographical Information System (QGIS) using a limited rational model to produce an output in the form of a boundary based on the provided function. The results showed that the proposed SNP buffer zone covering an area of 175,327.2 hectares which consisted of the forest mosaics, the agricultural land, the area of the settlement, the mixed gardens, the open land, the community villages, the oil palm plantations, and the other types of land use. Based on the land ownership status, the SNP buffer zone is approximately 131,037.75 hectares where the rest area of 44,289.45 hectares was owned by the community which has a regulation to use the land. The further analysis proved that the state-owned forest is the best area as the SNP buffer zone. By combining the ecological and socioeconomic aspects, the buffer zone was determined properly without ignoring the sustainability and socio-economic aspects. As the boundary, the distinctive ecosystem (peat dome) and the small unit of land use were found to separate the buffer zone and another part of SNP.
