Strategi Mitigasi Banjir Untuk Mendukung Perencanaan Pembangunan Wilayah Berbasis Mitigasi Bencana Di Kota Medan

Abstract

This research aims to identify flood-prone areas in Medan City, map the level of vulnerability, and formulate mitigation strategies based on regional development policies, especially structural mitigation. The analysis was conducted using spatial data based on remote sensing with Sentinel-2 imagery, Digital Elevation Model (DEM), CHIRPS data, and soil type and geology data. The level of vulnerability was determined using the scoring method, while mitigation strategies were analyzed using the SWOT method. The results showed that areas with high to very high vulnerability levels include Belawan Sicanang (1,047.07 ha, 12%), Martubung (1,032 ha, 11%), Besar (1,013 ha, 11%), and Pekan Labuhan (1,022 ha, 11%). The SWOT analysis resulted in four main strategies, namely optimizing levee and drainage infrastructure, utilizing early warning technology, increasing human resource capacity, and integrating flood mitigation in the Spatial Plan for long-term policies. This research is expected to serve as a basis for local governments and related parties in formulating effective flood mitigation and management strategies so as to minimize the risk and impact of flooding in Medan City
