JAKARTA - The construction of wave break water in Kelor Island, Thousand Islands Regency, DKI Jakarta Province, is directed to protect the Martello Fort Cultural Heritage object from the threat of rob and abrasion.

"'Break water' from the threat of rob or waves that eroded the walls of the fort," said Head of the Regional Technical Implementation Unit (UPTD) of the Maritime Museum, Mis'ari in Jakarta, Thursday, March 21, as reported by Antara.

As the manager of Kelor Island, his party appreciates the efforts made by the DKI Jakarta Water Resources Service (SDA) to support the rescue of Kelor Island.

"The construction of this 'break water' has had a good impact on the cultural heritage buildings there," he said.

Head of Rob Control and Coastal Development Division of the DKI Jakarta Provincial Natural Resources Service, Ciko Tricanescoro, said, "break water" is one of the coastal protective buildings that functions to reduce wave energy coming to the beach.

According to him, in the construction of "break water", a solid and strong material is needed in the face of sea waves and currents. Materials that are often used as raw materials for "break water" are made of concrete with a length of 380 meters.

"The beach, which is arranged by sand material, will easily change due to the process of wave and near-shore flow, causing a form of sediment movement that can move horizontally and vertically," he said.

This can result in beach erosion which causes land areas to be reduced due to eroded by sea waves and currents.

He assessed that to stabilize the coastline, it can be done by building a beach safety building in the form of a "break water"

"Therefore, in an effort to protect Kelor Island as a cultural heritage island, a break water was built to prevent abrasion from occurring," he said.
