The threat of the northern coast of Java and Jakarta sinking has prompted the government to move quickly to build a giant sea wall. The Coordinating Ministry for Infrastructure and Regional Development (Kemenko IPK) revealed that the government has already spent up to IDR 123 trillion to support the construction of sea walls along the northern coastline.
Agus Harimurti Yudhoyono (AHY), Coordinating Minister for Infrastructure and Regional Development, explained that the IDR 123 trillion budget has been allocated to support the construction of approximately 41 kilometers of sea walls along the Jakarta coastline.
“When asked how much, based on the studies we’ve conducted previously, it’s approximately US$8 billion or IDR 123 trillion, just for the Jakarta area, covering around 41 kilometers,” said AHY at the International Conference of Infrastructure (ICI) 2025 at JICC, Jakarta, on Wednesday (June 11, 2025).
In line with this, AHY hinted that the plan to build a giant sea wall along the northern coast of Java (Pantura), stretching from Banten to Gresik, would require a significantly larger budget.
Nevertheless, the construction of this sea wall is essential to protect the various economic centers scattered across the Pantura region.
Previously, AHY had stated that building a giant sea wall along the northern coast of Java (Pantura) would be difficult to realize due to limited funding available to support the construction of the Giant Sea Wall from Banten to Gresik.

Aligned with this, AHY said that the development of infrastructure to mitigate the rising sea levels would be carried out through several programs. These programs include building the Giant Sea Wall and developing areas to facilitate the relocation of communities that can reasonably be moved.
In addition, AHY noted that the government’s efforts to address tidal flooding will also involve planting mangroves along the coast.
“Therefore, once again, we must ensure that the strategy we choose at the time truly fits the situation. For example, a revitalization approach can be applied in areas that are not densely populated, where relocation might be the most reasonable option,” he concluded.
