Abstract
Coastal erosion and accretion have altered the shorelines of various Indonesian coastal areas, endangering the lives and livelihoods of coastal populations. Damage to beaches in coastal areas affects the community’s daily activities, the transportation system, industry, and trade, as well as the environment and public health. Based on this occurrence, the initial stage of disaster management study resulting from coastal damage is to identify the coast’s vulnerability to threatening harm. To assess coastal vulnerability, field observations and measurement from the research location were carried out to obtain visual damage observation, land use, lithology, tidal range, and beach slope. Coastline data from satellite imagery and wind data from the government agencies were carried out to obtain the rate of shoreline change, width of damage, length of damage, and wave height. The purpose of this research is to look at changes in the coastline of Serang, Banten Province, and analyse the amount of beach damage to set priorities for coastal management. The beaches explored were Karangantu Beach, Domas Beach, Lontar Beach, and Tengkurak Beach. Karangantu Beach’s level of vulnerability is classified as very high, so dealing with it is a top priority. Domas and Lontar Beaches are extremely vulnerable, so dealing with them is a key priority. Tengkurak Beach has a moderate level of vulnerability, hence the priority for managing is rather high. This can be utilized as a model for overcoming coastal damage in Serang District, Banten Province, by constructing coastal protection buildings based on the shore’s vulnerability and management priority.
