FLOOD DISASTER RISK ANALYSIS IN WEST ACEH REGENCY BASED ON THE INDONESSIAN DISASTER RISK INDEX

Abstract

Floods are one of the most frequent hydrometeorological disasters occurring in West Aceh Regency and have the potential to cause significant losses. This study aims to analyze the flood disaster risk level in West Aceh Regency based on the Indonesian Disaster Risk Index (IRBI). The research employed a qualitative approach using a case study method. Data were collected through observations, interviews, Focus Group Discussions (FGDs), and document reviews, and were analyzed using the Miles, Huberman, and Saldaña data analysis model. The results indicate that flooding is the disaster with the largest hazard coverage area in West Aceh Regency, covering 89,800 hectares and categorized as a high hazard level. Furthermore, the Disaster Risk Index (DRI) of West Aceh Regency during the 2016–2024 period remained in the high-risk category, although it decreased from 203.20 to 173.76. These findings demonstrate that strengthening disaster mitigation efforts and improving regional capacity are still required to sustainably reduce flood disaster risk.
