Jakarta Sinking and the Nusantara New Capital — 2026-09-27
This week's news centers on Nusantara's construction push: the IKN Authority reports continued progress on legislative and residential projects, while DPR leadership presses for 2026 targets to be met. In Jakarta, the subsidence-and-rob debate remains framed by the giant sea wall and groundwater control as the capital's functions slowly migrate.

Top developments
Legislative complex at IKN reaches 14.8% progress
DPD RI Chairman Sultan B. Najamudin inspected construction of the Legislative Complex at Nusantara in East Kalimantan on Tuesday, 22 September 2026, finding work at 14.8% progress. The visit was aimed at verifying how ready the infrastructure will be to support Nusantara's planned political functions
Parliament and judicial complex targeting 2027 completion for a "political capital by 2028"
IKN's combined parliament and judicial complex has reached 15% progress with completion targeted for 2027, ahead of Nusantara's role as Indonesia's political capital in 2028, according to national business reporting published 24 September 2026
Low-income housing (rusun MBR) at 88.22%, targeted done by end of 2026
The Ministry of Public Works and Housing confirmed on 25 September 2026 that low-income apartment blocks (rusun MBR) in Sepaku have reached 88.22% progress, with 65 housing units expected to be finished by the end of 2026 — key to easing accommodation constraints for relocated civil servants
IKN Authority chief upbeat: investors coming in, infrastructure and commercial airport on the table
IKN Authority head Basuki Hadimuljono gave a progress interview on 25 September 2026 outlining investor interest, private investment, infrastructure readiness, toll roads and plans for a commercial airport at Nusantara
Local view
Indonesian construction trade media (Top Konstruksi) notes that DPR Vice Chairman Sufmi Dasco Ahmad met with OIKN head Basuki Hadimuljono to scrutinize IKN development and press for the 2026 targets to be achieved — a sign that parliament is keeping direct supervisory pressure on the project timeline
Context & numbers
- Land subsidence in Indonesia's PT Free Zone evaluation research puts local rates as high as 20–28 cm/year in specific locations, while analyses often cite averages of 75–100 mm/year for Jakarta — the underlying reason for the capital move
- North Jakarta subsidence has been estimated around 4.9 cm per year, with groundwater overuse identified as the main cause
- The IKN Authority's 2026 budget allocation was reported at Rp 6.7 trillion, of which Rp 5.3 trillion is earmarked to continue the legislative-judicial complex works
- Presidential Regulation No. 79/2025 (signed 30 July 2025) ordered relocation of 1,700–4,100 civil servants to Nusantara during 2026
On the radar
- The 2028 "political capital" milestone: with the parliament/judicial complex at only ~15%, the pace of remaining works will be closely watched as the 2027 completion target approaches
- Commercial airport plans at IKN flagged by Basuki Hadimuljono — details and investors still to be announced
- End-2026 completion of the Sepaku rusun MBR housing (65 units, currently 88.22%), a prerequisite for further civil servant relocations
- Private capital's expanding role as public funding for the new capital is trimmed in the 2027 budget — watch for new private investment announcements or their absence
