The coastal vulnerability analysis is a fundamental phase towards effective risk reduction. The main focus of this study is to conduct a coastal vulnerability analysis in the Sunda Strait. The research location was carried out along the coastline of the Sunda Strait, which was mapped into 493.5 km of Lampung coastline and 269.5 km of Banten coastline, divided into a total of 206 segments. The method used in analyzing coastal vulnerability is the Coastal Vulnerability Index (CVI) method by assessing three geological parameters (Geomorphology, rate of coastline change, coastal slope) and three oceanographic parameters (tidal range, significant wave height, and relative sea level change). Based on the results obtained, in general, the coastal vulnerability in the Sunda Strait consists of low, moderate, high, and very high categories. Along the Lampung Province coastline, 135.7 km (27.5%) is categorized as low vulnerability, 114.49 km (23.2%) as moderate vulnerability, 150.34 km (30.46%) falls into the high vulnerability category, and 92.95 km (18.83%) of the mapped coastline is classified as very high vulnerability. Meanwhile, along the coastline of Banten Province, 62.76 km (23.29%) is categorized as low vulnerability, 84.07 km (31.2%) as moderate vulnerability, 43.99 km (16.32%) falls into the high vulnerability category, and 78.68 km (29.19%) is classified as very high vulnerability. Parameters that significantly influence the level of coastal vulnerability in the Sunda Strait are geomorphology, the rate of coastline change, coastal slope, and significant wave height. While the parameters of tidal range and relative sea level change remain constant. The findings of this research have the potential to furnish an up-to-date vulnerability map and crucial information pertaining to the coast of the Sunda Strait. The primary objective is to enhance awareness among decision-makers and stakeholders involved, prompting the formulation of strategies for mitigation and adaptation. Additionally, the results can be used as basic data for further risk analysis.
