PENERAPAN FUZZY LOGIC DALAM PEMBUATAN PETA ELEMENT AT RISK BENCANA LUAPAN BANJIR SANGAI AIR BENGKULU KOTA BENGKULU

Abstract

Flood is a disaster that can cause loss and damage in various fields, especially infrastructure. One effort to prevent and reduce the impact of flood is by making simulations through spatial modeling in the form map of element at risk. In making map of element at risk, data input in the form of a map downloaded from the Open Street Map containing infrastructures and natural features from disaster simulations made using Fuzzy logic. The application of Fuzzy logic is used to interpret vague statements of the percentage of the building area affected in each classification of flood overflow areas into a logical understanding of the damage classification of "Berat", "Sedang" and "Ringan". Based on the results of the flood disaster simulation, it was found that the number of buildings impacted by the overflowing floods of the Air Bengkulu River was 37 buildings "Rusak Berat", 216 "Rusak Sedang" and 329 "Rusak Ringan", with 2,328 fatalities.
