Suitability Evaluation of Land Use/ Land Cover (LULC) Towards Landslide Prone Areas in Structural and Volcano Landform

Abstract

North Bandung area covering structural landforms and volcanoes has an active volcano and fault, leading to potential of landslide. This study aims to create a new scheme of LULC zones based on a landslide prone area. The landslide zone is analyzed through Fuzzy through the following variables: rainfall, drainage distance, drainage density, slope angle, slope aspect, distance lineament, elevation, slope curvature, and topographic wetness index (TWI). The LULC is created based on Landsat-8 image. The suitability evaluation of the LULC area is analyzed using overlay onion and query to obtain region suitability results. The landslide analysis results in three classifications including high (3.626,97 ha), medium (5.294,53 ha), and low (1.117,69 ha). It is also found that there is a functional change by 11.87% (4,632.01 ha) from the total area as well as a type change from rice field and built-up into orchard and field. On the functional shift classification of orchard, the land can be used for palms, bamboo, kawung, and sugar palm whose core has small roots gripping the ground material enabling them to have high vegetation density. On the land with 15% slope, terracing and annual planting are recommended to keep the land productive and reduce landslide prone.
