According to the president's envoy, the program aims to protect rice fields on the north coast of Java Island.
He drew attention to public concerns about the sea wall, particularly the threat posed by rising sea levels to fishermen.
Hashim stated that plans for the giant sea wall had been in development since 1994, highlighting that the government recognized the dangers posed by rising sea levels at that time. However, the project has not been realized.
The envoy projected that the giant sea wall's construction could take 10 to 20 years.
Earlier, President Prabowo instructed his ranks to review the construction of a giant sea wall extending from Jakarta to Cirebon as part of a National Strategic Programme (PSN) in 2025.
Coordinating Minister for Economic Affairs Airlangga Hartarto noted that the construction of the Jakarta-Cirebon giant sea wall project will connect with existing flood and tidal control embankments in Tambaklorok, Semarang, Central Java.
