Investor Daily - Tangani risiko banjir, Kementerian PU bangun tanggul pantai Jakarta
10 June 2025
The Ministry of Public Works is addressing the issue of land subsidence and aiming to reduce flood risk in Jakarta through the construction of coastal defences. The Jakarta Coastal Embankment Project forms part of the National Strategic Projects (PSNs).
Minister of Public Works Dody Hanggodo announced that the Ministry, via the Directorate General of Water Resources, has prepared the seventh phase of embankment construction along the northern coastline of Jakarta Bay.
Phase 7, Package 1 involves coastal protection works at Ancol River and Dadap River. The Ancol River embankment is planned to extend 100 metres, funded by the State Budget (APBN), and will be implemented under a single-year contract in 2025. The project is currently in the pre-tender stage.
“Coastal protection is one of the Ministry of Public Works’ priority programmes and forms part of the National Strategic Projects (PSNs),” said Minister Dody in an official statement issued in Jakarta on Monday, 9 June 2025.
The next part of Phase 7 will cover 850 metres across Ancol, Muara Baru Barat, and Cilincing Rivers. Funding for this segment is currently being proposed through State Sharia Securities (SBSN) and is planned as a multi-year contract between 2026 and 2027.
This phase will also include the construction of a polder system at Dadap River, which will function as an integrated flood control mechanism under the Integrated Coastal Development of the National Capital (PTPIN). The polder is also set to be funded by SBSN and carried out under a multi-year contract between 2026 and 2027.
As of 2024, the Ministry has built 14.75 kilometres of Jakarta’s coastal embankments across six phases, covering areas such as Kalibaru, Kamal Muara, Muara Baru, Ancol, and Dadap Rivers.
The Ministry stressed that sea wall construction is part of a broader flood control system, which also encompasses clean water provision and wastewater management.
This initiative is integrated with the construction of the Karian and Jatiluhur Dams to secure water supply, as well as the Jakarta Sewerage Development System to improve water quality in downstream areas.
Such an integrated approach is expected to reduce the risks of flooding and erosion while helping to prevent further land subsidence caused by excessive groundwater extraction.
Previously, the government continued to refine the design of the Giant Sea Wall mega-project to attract both domestic and international investment. The development plan includes housing, business centres, and recreational facilities.
To realise the 946-kilometre sea wall, President Prabowo Subianto assigned Coordinating Minister for Infrastructure and Regional Development Agus Harimurti Yudhoyono to establish a special task force for managing the northern coast of Java.
Funding for the Giant Sea Wall—stretching from Banten to East Java—will not rely solely on the State Budget (APBN) and will require private sector involvement.
Speaking at the Ministry of Public Works’ Regional Consultation in mid-May 2025, Minister Agus stated that the government is working to harmonise early designs and development concepts for the sea wall project. He emphasised the need for collaboration between the Ministry of Public Works and Bappenas to align existing plans and concepts under a unified framework.
Currently, the northern coastal region of Java—particularly North Jakarta—is experiencing rising sea levels and significant land subsidence, necessitating a long-term strategic response.
