Harita Continuous Improvement Winners Advance to Group-Level Competition

Winners of the Harita Continuous Improvement (HCI) competition at the business unit level have introduced a range of innovations aimed at improving productivity, efficiency, and workplace safety. They will now advance to the group-level competition, where they will compete for the overall championship title.

These innovations were recognized during the HCI Awarding Night 2025, held in early October 2026. Each solution was developed in response to real operational challenges, ranging from maintaining mining productivity during rainfall to improving energy efficiency, accelerating licensing processes, and managing occupational health risks.

In the mining sector, the Production Department team from PT Trimegah Bangun Persada (TBP) and PT Gane Permai Sentosa (GPS), led by Fransisco Yustian Mangalik, developed a controlled mining method for rainy conditions at Pit Senggigi using the Road Severity Index (RSI). This approach helps assess road conditions and determine whether mining operations can safely continue.

Between October and December 2025, the implementation reduced lost production hours by 21% and tonnage losses by 27%, equivalent to 60,048 wet metric tons (WMT). These results demonstrate the potential of data-driven approaches to maintaining productivity while prioritizing workplace safety.

Meanwhile, PT Megah Surya Pertiwi (MSP) introduced an energy efficiency innovation by converting diesel-powered excavators to electric power. Following technical and safety testing, along with operator training, the initiative is projected to generate energy cost savings of approximately IDR 106 million per unit per month. Beyond reducing operational costs, the transition to electric power also offers opportunities to lower operational emissions.

Innovation also extended beyond field operations. PT Halmahera Jaya Feronikel (HJF) developed an initiative titled "Transforming the Effectiveness of Electricity Licensing to Support Independent Integrated IUPTLU Licensing." By managing electricity licensing processes independently, the company has been able to accelerate permit completion by up to 100 days, supporting smoother and more efficient operations.

In occupational health, the BreatheSafe Squad team from PT Halmahera Persada Lygend (HPAL), led by Priyo Adi Pamungkas, developed an approach to monitoring nickel sulfate dust exposure. Involving 108 Harita employees, the team integrated air quality data with workers' health indicators as the foundation for an Integrated Exposure Management System. The proposed system is designed to combine risk mapping, exposure monitoring, and early detection into a comprehensive occupational health management approach.

Harita Nickel President Director Roy Arman Arfandy expressed his appreciation for the improvement initiatives developed by employees.

"The spirit of continuous improvement is part of our shared culture at Harita Nickel. We are very proud of the dedication and determination of our people to continuously strive for excellence," he said.

He also expressed hope that these innovations would continue to be implemented and refined, ensuring their benefits could be sustained over the long term.

With the business unit-level competition concluded, the winners are now preparing for the next stage at the group level. Each team will bring forward its innovation, competing to demonstrate solutions with the potential to deliver broader improvements across Harita Nickel's operations.

Through HCI, Harita Nickel continues to encourage employees to identify challenges, develop practical solutions, and continuously improve work processes. This commitment reflects the spirit of #CaranyaHarita, fostering a culture of continuous improvement to build safer, more effective, and more efficient operations.
