Government Maps Out 15 Segments of Giant Sea Wall from Serang to Gresik

The Head of the North Java Coast Management Authority, Didit Herdiawan, stated this after a limited meeting with President Prabowo Subianto discussing the progress of the Giant Sea Wall construction on Tuesday (12/5/2026). According to him, the government is still examining the conditions of each region before the project is implemented.

“So, we also reported earlier that in Java, particularly in the North Coast area, there are 15 segments. And we are delving into them, from Serang to Gresik, for the thematic areas,” Didit said.

Didit stated that the government still requires further evaluation and assessment regarding the conditions of each area, including the social and economic impacts on communities in the affected regions. According to Didit, the North Coast area has long been a centre of economic activity for the community, from fishermen, farmers, to aquaculture farmers.

Therefore, the government wants to ensure that mitigation aspects as well as social-economic impacts are the primary focus in the project implementation. “Indeed, in that area, there are economic activities carried out by the community. Precisely with mitigation and social-economic issues, these will be accompanied in the implementation of the construction activities,” he said.

Didit revealed that several priority points for the Giant Sea Wall construction have actually been discussed in previous coordination meetings. However, the government has not yet made a final decision because it still requires more in-depth studies.

“For the prioritised points, yesterday during the IPK Coordination Meeting, we already had several points that are alternatives in the implementation of the construction activities. However, these points have not yet been decided further because they need to be delved into,” he said.

“First, for example, Jakarta Bay, in Central Java, West Java, and so on. But for the 15 segments, there are sub-segments and sections within them that require collaboration,” he continued.

Regarding the construction schedule, Didit said the government is still calculating the project implementation timeline through backward planning. According to him, all components must be included before the final schedule is set.

“For the timeline, we are arranging the implementation of these activities, calculating the backward planning for how long. Because all components must be included,” he said.
