In 2020, the length of coastal abrasion in Rangsang Barat District will reach 10.75 km2. West Rangsang District is an area located on the coast which has strong wave and wind currents. For this reason, coastal abrasion disasters that occur must be overcome by implementing structural and non-structural mitigation to minimize the risks arising from coastal abrasion disasters that occur.
