Development of Coastal Protection Structure in Karawang Coastal Area of Indonesia

Abstract

This research is a case study on the coast of Karawang Regency, West Java Province, which is part of the North Coast of Java. In the coastal area of Karawang, it was previously planned to build a port, but it was canceled and shifted to another regency. How is the condition of the Karawang coast? Has it undergone physical changes and is it risky if a port is built, and do it need some coastal protection strutures to protect it from damage? What kind of coastal structures are suitable to protect the coast of Karawang? These question are at the same time a problem that will be raised in this study. The objectives of this research are: (1) to plan a coastal protection structure for the coast of Karawang; (2) to determine the type and structure of coastal protection structures that are suitable for the Karawang coast. Research data in the form of primary and secondary data, with primary data covering topography, bathymetry, tides, currents, obtained by validation through Ground Check Points (GCP), and secondary data covering wind, and socioeconomic. Analysis of the data through simulation and determination of the selected coastal structures, with the result that the appropriate coastal protection structures are breakwaters and groynes, because they can reduce the overflow of waves that occur, so that the coast is protected from the onslaught of damaging waves.
