Jakarta, INTI – Indonesia’s demand for aluminum continues to rise in line with rapid infrastructure development, manufacturing expansion, and the growth of electric vehicles. Amid pressure from increasing demand and the challenge of maintaining supply resilience, Indonesia underscores the importance of adopting more sustainable strategies. This momentum was reflected in a series of technical activities and industrial evaluations held in North Sumatra on Monday, November 17, 2025, highlighting the role of green energy and human resource quality as key solutions. As global markets fluctuate, efforts to reinforce the foundation of the aluminum industry are considered crucial for future competitiveness.
Aluminum Industry Becomes a Strategic National Issue
The growing domestic consumption of aluminum has made the supply of primary aluminum a critical issue for Indonesia’s industrial resilience.
Indonesia Asahan Aluminium (INALUM) has managed to maintain its operations through a combination of green energy and production efficiency, making it a real example of how a major industry can remain competitive despite global price volatility.
Green Energy from Hydropower Sets INALUM Apart
INALUM utilizes environmentally friendly electricity sourced from two hydropower plants (PLTA) harnessing the natural flow of Lake Toba to the Asahan River. This initiative has positioned INALUM as one of Asia’s pioneers in green smelting, even before the global discourse on green industry became mainstream.
The support of green energy also drives large-scale conservation programs. Throughout 2024, INALUM planted more than 871,000 trees across over 2,200 hectares and aims to restore 500 hectares of critical land in 2025.
Daniel JP Hutauruk, Head of INALUM’s Strategic Services Group, explained that the modernization of the hydropower turbines saved up to 35 million cubic meters of water per year while generating an additional 20,168 MWh of energy.
Downstream Industry Strengthens the National Aluminum Value Chain
Aligned with President Prabowo Subianto’s Asta Cita agenda, INALUM continues to advance mineral downstreaming by processing bauxite into alumina and aluminum. This effort strengthens Indonesia’s aluminum value chain, ensuring the country is not merely an exporter of raw materials.
However, the company’s strength lies not only in its industrial facilities but also in its local workforce. Of nearly 4,000 employees, around 80% come from North Sumatra, fostering intergenerational competency continuity and strong ties to the surrounding environment.
According to Ismadi from the Ministry of Energy and Mineral Resources (ESDM), approximately 1,820 employees hold organic positions, while around 1,970 are outsourced personnel.
Innovation as the Driver of Production Resilience
INALUM’s culture of innovation is reflected in initiatives ranging from the use of Robotic Servo Arms to improve workplace safety to enhancements in the potline system, which can add 110 tons of molten metal per furnace per year.
These innovations helped INALUM achieve an All-Time High Production record in 2024, reaching 275,000 tons of aluminum annually. During TIS 2025, a total of 166 participants competed with ideas to increase production capacity to 450,000 tons per year.
Conclusion
Industrial resilience is not solely determined by machine modernization or investment size. Its most essential foundation lies in clean energy, structured downstreaming, and a continuously innovative workforce. With this combination, Indonesia has a strong opportunity to reinforce its position as an important player in the global aluminum industry in the future.
