| Summary: | Indonesia has 95,181km of coastline, one of the longest in the world. With such a long coastline, coastal erosion is an issue that has never been absent in Indonesia. This issue greatly affects the lives of coastal communities who are disturbed by the receding coastline every year. For this reason, natural coastal protection such as mangroves, which are relatively cheaper and easier to build, can be used for thousands of coastal villages. However, mangroves take time to grow and become mature mangroves that can protect the coast more effectively. In order to protect the mangroves from ocean waves, temporary coastal protection structures are needed until the mangroves grow up. This combination of natural and artificial coastal protection structures is called hybrid engineering and is being widely discussed in Indonesia.
In this Final Project, 3 models are tested, namely bamboo pile breakwater overgrown with green mussels with rope model and bead model, as well as pile group breakwater in resisting extreme waves. This research focuses on choosing the best model and configuration shown by the smallest structural and system transmission coefficient. There are three configurations for each model to determine the effect of breakwater width, breakwater row spacing, breakwater column spacing, and wave steepness on the transmission coefficient.
