District clustering in Malang City based on natural disaster vulnerability: basic polity formulation in disaster management

The primary objective of this study is to assess the vulnerability to natural disasters in various sub-districts within Malang City, utilizing secondary data from the Central Statistics Agency (BPS). Additionally, it seeks to recognize and analyze distinct vulnerability patterns within each sub-district and establish a more effective disaster management policy framework tailored to the specific vulnerability characteristics of each sub-district cluster. The research employed cluster analysis to categorize sub-districts with comparable vulnerability characteristics. As a result, two distinct clusters emerged: Cluster 1 comprising the Sukun and Blimbing sub-districts, characterized by a higher vulnerability rate, and Cluster 2 encompassing the Kedungkandang, Klojen, and Lowokwaru sub-districts, which exhibit a lower vulnerability rate. This shows a significant difference in vulnerability to natural disasters between sub-districts in Malang City. This research approach is expected to provide a deeper understanding of disaster vulnerability in each sub-district to help formulate more effective disaster management policies on the characteristics of vulnerability in each sub-district cluster.
