Ministry of Public Works Implements A30 to Strengthen Construction Material Self-Sufficiency
Jakarta (ANTARA) - The Ministry of Public Works (PU) has begun applying a 30 per cent Buton asphalt (asbuton) mixture, known as A30, on several strategic toll road sections as a step to strengthen national construction material self-sufficiency while reducing dependence on imported asphalt.
Public Works Minister Dody Hanggodo said the use of asbuton forms part of the government’s strategy to strengthen domestic industry, increase the added value of national natural resources, and maintain infrastructure spending efficiency amid global commodity price dynamics.
“The reason for using A30 asphalt is to reduce asphalt imports,” said Dody in Jakarta on Saturday.
The policy implements Minister of Public Works Regulation Number 10 of 2026 on the Processing of Refined Buton Asphalt for Road Construction and Preservation, which provides the foundation for the use of refined asbuton in Indonesia.
According to Minister Dody, the A30 implementation will be carried out in stages using an approach similar to the biodiesel blending policy, such as B10 through to B20. The asbuton blending percentage will continue to be increased in line with industry readiness, technical evaluation results, and economic considerations.
“So we will gradually raise the Buton asphalt content, while still paying attention to its economic value. This ensures that the state budget normally used to build and preserve roads does not balloon,” he said.
Beyond supporting the strengthening of national industry, the use of asbuton is also expected to reduce the impact of world asphalt price fluctuations on infrastructure development financing.
To date, Indonesia still relies on imports to meet most of its national asphalt needs, even though Buton Island in Southeast Sulawesi holds very large natural asphalt reserves.
As an initial implementation stage, the A30 mixture will be applied to several strategic toll road sections that are also designed to serve a dual function as emergency runways for Indonesian Air Force fighter jets, namely the Banda Aceh–Sigli Toll Road, the Jakarta–Cikampek II South (Japek II South) Toll Road, the Terbanggi Besar–Pematang Panggang–Kayu Agung Toll Road, and the Probolinggo–Banyuwangi Toll Road.
The use of asbuton on these sections is expected to demonstrate that domestic materials can meet technical standards for strategic national infrastructure, including infrastructure with both civil and defence functions.
Through the implementation of Ministerial Regulation Number 10 of 2026, the Ministry of Public Works reaffirms its commitment to expanding the use of asbuton in stages for road construction and preservation across Indonesia.
The policy is expected to strengthen the resilience of the construction material supply chain, enhance the competitiveness of the national asphalt industry, and maintain the quality of infrastructure built while keeping the efficiency of state budget utilisation in mind.
