The need for land has increased every year, and this increase is caused by the rate of population growth, resulting in changes in land use. Uncontrolled land-use conversion has led to catastrophic flooding in the Antokan watershed. The purpose of this study was to determine the direction of land-use change policies in the Antokan Watershed, West Sumatra Province. To determine land-use change using the GIS method with the overlay technique of land use maps for the period 2000-2020. Furthermore, to determine the policy direction using the ISM method involving 20 experts. Research results in the Antokan watershed have shown changes in land use of 4.178 hectares during the 2000-2020 period. Changes occur in forest areas, mixed gardens, shrubs, and rice fields which have decreased, on the other hand, settlements, plantations, and open land have expanded. Furthermore, two sub-elements are the priority for policy direction to reduce the rate of land-use change, namely making regulations and firm sanctions on land use errors (E3) and consistency in enforcing land use laws (E4). © 2021, Pusat Penelitian Lingkungan Hidup - Lembaga Penelitian dan Pengabdian Kepada Masyarakat Institut Pertanian Bogor (PPLH-LPPM IPB).
