Evaluation of Coastal Protection Structures (Revetment) and Management of Affected Communities on the Palu Bay Coastline

Disaster mitigation and coastal protection, a coastal protection structure in the form of a revetment was built. This study aims to evaluate the technical effectiveness of the revetment that has been built, as well as to review the social handling of the affected community in the coastal area of Palu Bay. The research method used is descriptive with a qualitative and quantitative approach, through the collection of primary and secondary data. This method is used to provide a clear picture/description of a situation without treatment of the research object and the suitability of the design to the characteristics of the beach, and the level of damage due to abrasion or waves. Social handling is evaluated through field studies, interviews with affected communities, and analysis of relocation and rehabilitation policies. The results of the study indicate that some revetment structures have functioned in reducing the rate of abrasion, but there are several segments that have been damaged due to lack of maintenance and designs that are not fully adaptive to local conditions. Periodic evaluation of coastal infrastructure is needed as well as more participatory and sustainable policies for handling affected communities to support the resilience of the Palu Bay coastal area.
