The Indonesian government has entered the second phase of development for the Nusantara Capital City (IKN) project, focusing on the integration of private sector investment to stimulate economic growth across East Kalimantan. According to the Nusantara Capital Authority (OIKN), this phase prioritizes the construction of essential infrastructure and facilities to support a functional administrative core, aiming to transition the region from a resource-dependent economy to a modern, service-oriented hub.
How Phase II Shapes Economic Growth
The second phase of the IKN project shifts the focus from initial land clearing and foundational works to the development of vertical infrastructure and commercial facilities. The Ministry of National Development Planning (Bappenas) reports that this stage is designed to attract domestic and international capital by providing ready-to-use land plots for private developers.

By prioritizing the "Work-Live-Play" ecosystem, the government intends to create a multiplier effect. As office buildings, residential complexes, and public amenities rise, the demand for local construction materials, services, and labor increases. This shift is intended to move East Kalimantan’s economy beyond its traditional reliance on coal and palm oil, fostering a more diversified industrial base.
What Infrastructure Projects Are Prioritized
Development in this phase centers on connectivity and urban functionality. According to the Ministry of Public Works and Housing (PUPR), current projects include:

- Transportation Networks: Expansion of toll roads and arterial streets to link the new capital with the major cities of Balikpapan and Samarinda.
- Public Facilities: Construction of hospitals, educational institutions, and government housing units to accommodate the expected influx of civil servants and private sector employees.
- Smart City Integration: Deployment of digital infrastructure, including fiber-optic networks and smart traffic management systems, to ensure the capital operates as a modern, technology-driven city.
Why East Kalimantan Matters
The relocation of Indonesia’s capital from Jakarta to East Kalimantan is a strategic move to address overcrowding and regional economic inequality. The Indonesian government emphasizes that the IKN project serves as a catalyst for "Indonesia-centric" development, shifting the center of gravity away from Java.

Compared to previous large-scale infrastructure projects in Indonesia, the IKN development is unique in its reliance on a public-private partnership (PPP) model. While the government finances foundational roads and administrative buildings, private investors are expected to lead the development of commercial districts and leisure facilities. This approach is intended to reduce the burden on the national budget while ensuring the city remains sustainable and economically viable in the long term.
Future Outlook
The transition into the second phase marks a critical test for the project’s timeline. With major ground works now largely complete, the visibility of vertical construction will serve as a key metric for investor confidence. According to data from the OIKN investment portal, the government continues to offer fiscal incentives, including tax holidays and streamlined permit processes, to accelerate private sector participation. The success of these efforts will determine whether the region can sustain the projected growth as the administrative transition gains momentum through 2025 and beyond.
