Jakarta Governor Pramono Anung Wibowo stated that the rob flood hitting North Jakarta and the Thousand Islands a few days ago was caused by the supermoon phenomenon. The DKI Provincial Government had anticipated the event 15 days in advance with preparations at various vulnerable points. Pramono emphasized that similar rob floods will still occur in the future.
The supermoon phenomenon, or perigee full moon, was the main cause of the rob flood that struck North Jakarta and the Thousand Islands a few days ago. DKI Jakarta Governor Pramono Anung Wibowo explained this during an encounter in North Jakarta on Monday (December 8, 2025). "Yesterday's rob indeed happened because of the supermoon. So, supermoon is a full moon," he said.
The DKI Provincial Government had prepared anticipations 15 days in advance, including in Muara Baru, Muara Angke, R.E. Martadinata, and other locations. In his 10 months of leadership, Pramono has made rob flood handling a top priority. He expressed gratitude for the readiness of government-owned water pumps that helped mitigate the impact.
Pramono warned the public that rob floods remain a potential risk in the future, so the Provincial Government will continue anticipations at critical points. Coordination is underway with the Ministry of Public Works, Ministry of Marine Affairs and Fisheries, Pelindo, and the DKI Water Resources Agency (SDA).
Additionally, Pramono inspected the sea wall in Muara Baru, Penjaringan, which had leaked and gone viral. He promised to address the leakage promptly to prevent future rob floods. "We will handle it immediately, because now, rob for next month or months ahead will definitely still happen," he said. Although primary responsibility lies with Pelindo, the DKI Provincial Government will collaborate.
SDA Head Ika Agustin Ningrum stated that strengthening the NCICD phase A wall structure is underway using grouting, shotcrete, 3-meter excavation, and K500 concrete pouring. Currently, work covers 400 meters downstream of Nizam Zachman and will extend to 1 kilometer, following initial emergency handling per SOP.
For the National Capital Integrated Coastal Development (NCICD) project, the Provincial Government has budgeted for continuation in 2026: Pluit 530 meters, Muara Angke 350 meters, and Kali Lencong 750 meters. In 2025, construction includes Ancol 1.2 kilometers, Muara Angke wall 1.1 kilometers, and Bywalk Pluit 400 meters out of a 600-meter target.
