Indonesia is reviewing 15 coastal segments along northern Java for a giant sea wall project, as authorities advance planning for a 575-kilometer coastal protection scheme.
Deputy Minister of Marine Affairs and Fisheries, as Head of the Java North Coast Management Authority, Didit Herdiawan Ashaf said the segments from Serang to Gresik are being assessed for thematic and technical feasibility.
"We have reported that in Java, especially along the northern coast, there are 15 segments and these are being studied in detail from Serang to Gresik based on local characteristics, requiring further assessment," Didit said after a cabinet meeting at the presidential palace in Jakarta on Tuesday (May 12).
He explained potential sites discussed in earlier coordination meetings, including Jakarta Bay and several locations in Central and West Java, remain under review with no final decisions made.

"However, the locations have not been finalised as further assessment is still required," he added.
The government plans to divide the 575-kilometer northern Java coastline into 15 segments, with further sub-segmentation within each segment for phased construction of the giant sea wall, aimed at reducing coastal risks and land subsidence.
Didit said the implementation timeline is still being developed, as the project must integrate technical, environmental, and social considerations.
He added that construction will be carried out thematically, taking into account existing economic activity along the coast to align development with local livelihoods and mitigation needs.
