    The flood disaster has caused many losses to human life. In an effort to reduce the impact caused by natural disasters, it is necessary to have disaster mitigation. Making maps of flood-prone zones is one form of non-structural mitigation. The purpose of this study was to determine the zoning level of flood vulnerability, design a dynamic model of flood vulnerability, and develop a floodprone area policy in Limapuluh Kota Regency, West Sumatra Province. The method used for the manufacture of flood-prone zones using a geographic information system (GIS) using GIS 10.1 software, then to determine dynamic modeling using a systems approach analyzed with powersim 10. Conclusion 1) Land use for gambir plants (Uncaria Gambir) has a large impact against floods. The mining activities of the excavated land also have a significant effect on the increase in flood disasters. 2) The study area consisted of three flood-prone zones, namely high vulnerability, 6.2% of the total area, prone zones while 50.6% zones were around 43.2% low hazard zones

    Natural disasters will bring harm to human life, and one of the efforts to minimize that is with disaster mitigation. Determination of landslide hazard zones in settlement areas is part of mitigation efforts in the sustainable use of land resources. The purpose of this study is to map the landslide hazard zone in the settlement area in Tanah Datar District. For the determination of landslide hazard zone, an overlay method is used by scoring technique using geographic information system (GIS). The analysis shows that Tanah Datar District has 35,6 percent of high landslide hazard areas, and about 38 percent of settlement areas are in high landslide hazard zones
