Abstract

Flooding has become a seasonal disaster in Bangkalan Regency, linked to the policy incoherence especially in spatial planning, water resource management, infrastructure, environmental considerations, institutional frameworks, and community participation. This study aims to identify gaps in flood management policies and formulate policy alternatives to strengthen flood resilience in Bangkalan Regency. The policy analysis was conducted through a review of regulations, regional development planning documents, government technical documents, secondary data, and relevant literature. The analytical process involved problem identification utilizing some root cause analytical methods such as Fishbone Analysis, 5 Whys Analysis, Policy Gap Analysis, the formulation of policy alternatives, and Multi-Criteria Analysis (MCA). Three policy alternatives Grey Infrastructure, Green Infrastructure, and Hybrid Integrated Flood Management (Hybrid IFM) were analyzed based on effectiveness, efficiency, implementability, sustainability, and institutional support. The MCA results yielded scores of 4.65 for Hybrid IFM, 3.55 for Green Infrastructure, and 3.50 for Grey Infrastructure. Based on these findings, Hybrid IFM was formulated as the recommended flood management policy for Bangkalan Regency.
