Abstract:
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
