Abstract

This research originated from basic research conducted in 2015 on coastal ecosystem restoration in Malang Regency and Gresik Regency, East Java Province. The results showed that coastal areas in Gresik Regency are very vulnerable to flood disasters and the intensification of anthropogenic processes. In 2022, it continued with applied research related to disasters in the coastal areas of the Gresik and Lamongan Regencies. The results showed that the highest level of vulnerability along the Gresik Regency coastline was the coastline in Tanjung Widoro Village, Bungah District of the Gresik Regency. Problems that occur are that tidal flooding annually affects the coastal area of Tanjung Widoro. This disaster washed away hundreds of hectares of milkfish ponds ready for harvesting. This research aims to commercialize the results of the 2022 research by developing shoreline management innovations using mangrove forest ecosystem restoration to prevent coastal flooding disasters. The research method uses spatial analysis with remote sensing images and generalized structured component analysis to determine community attitudes and perceptions of disaster, Driver-Pressure-State-Impact-Response (DPSIR) framework, and analytical hierarchy process analysis. The results showed that, according to the prediction results, changing shoreline from 2023 to 2033 can reach more than 145 submerged ponds or about 158.4 ha. To prevent it, restoring mangrove forests along the 11-km coastline is necessary to withstand tidal floods.

 

Keywords: shoreline, tidal flooding, ecosystem restoration, flood management, Gresik Regency.
