Settlement Suitability Analysis Based on the Catastrophic Eruption of Sinabung

Abstract

Mount Sinabung is an active volcano after being 'dormant' for a long time since the 1600s. Sinabung has begun to show its activities from 2010 to 2020, so that it has a long impact on community activities, damage to settlements, agricultural and threats to the lives of residents around Sinabung. This study aims to determine the conditions of land use in disaster-prone areas in relation to spatial patterns and levels of disaster prone. The research method is carried out through spatial analysis by overlaying the land use map with the spatial planning map to produce a land use suitability map. The spatial pattern suitability map is overlaid with a disaster hazard map to determine the level of security in settlements. The results showed that 5 affected Districts, namely in the Districts of Naman Teran, Payung, Simpang Empat, Tiganderket, Munte, the safe zone was 145.66 hectares, the less safe zone was 0.98 hectares, the unsafe zone was 36.91 hectares and the very insecure zone was 1.25 hectares. It is hoped that the spatial analysis regarding the distribution of safe locations for settlements is expected to become a policy material for the government to formulate arrangements for the use and utilization of space so that the spatial planning policies that are established are in line with efforts to reduce the risk of the eruption of Mount Sinabung disaster.
