The New Face of Mining in South Halmahera: When Local Women Lead Change
The nickel mining and processing industry is often depicted as a harsh, noisy, and high-risk masculine world. However, in the operational landscape of Harita Nickel on Obi Island, South Halmahera, that narrative is slowly changing. Emancipation is no longer mere rhetoric but is embodied in the dedication of a series of resilient women. They not only hold strategic control on the front lines of safeguarding occupational safety and ecosystem preservation but also serve as the driving force in weaving social harmony with the community. Their stories prove that in an industry traditionally dominated by men, there is real space for equal creation and leadership. Here, opportunities are no longer measured by gender but by competence.
Local Daughters on the Front Lines: Safeguarding Harmony and Safety
The presence of native local daughters in strategic positions represents the strongest embodiment of inclusivity at Harita Nickel. Margarita Luwudara and Yufita Tuhuteru are two native heroines of Obi Island who hold important control in two vital pulses of the company: social and technical operations.
Margarita, who serves as Community Relations Superintendent at PT Trimegah Bangun Persada (TBP) Tbk, has been a crucial bridge between the company and the community since 2018. As a resident of Kawasi, the main operational ring village, Rita brings an empathetic local perspective to ensure every social programme hits its target.
“As a child of Obi, I am grateful for the company’s support. This has a significant impact on our future, and I hope the young generation of Obi dares to dream,” said Rita. For her, this role is not just a profession but a path to empowering her birthplace.
If Rita nurtures social harmony, Yufita Tuhuteru guards the hard technical front with high risks. As a Process Safety Engineer at PT Halmahera Persada Lygend (PT HPL), this native woman from Soligi Village holds control over process safety in the factory producing raw materials for electric vehicle batteries.
Armed with a master’s degree in chemistry from Gadjah Mada University (UGM), Yufita ensures all installations are safe from fatal scenarios. For her, maintaining factory safety is not just about complying with operational standards but a form of love in protecting colleagues as well as the villagers of her birthplace from various risks.
Taming Natural Challenges for Sustainability
Mining operations always run alongside nature. For PT TBP Tbk, the high rainfall on Obi Island is a daily challenge that demands extra precision. At this critical point, Esmar Sulea Datu Lalong, Senior Mine Hydrology Engineer, and Mira Marlinda, Environment Supervisor, take on their roles.
They shoulder vital responsibility in managing runoff water. One focus is on the Tugu Raci 2 sediment pond, which spans 43 hectares. “Water quality is strictly controlled through physical and chemical methods to meet quality standards before being returned to the environment,” explained Esmar and Mira.
A similar challenge but in a different realm is faced by Rahma Maulida. As a Laboratory Assistant Engineer at the Dry Stack Tailing Facility (DSTF) of PT HPL, Rahma is tasked with monitoring water quality in the placement area for processing residues. She conducts strict monitoring at the inlet and outlet points every day to ensure operations are free from potential pollution and landslides.
From Coastal Conservation to a Culture of Compliance
Concern for environmental sustainability does not stop at the mining area but extends far to coastal regions by Putri Wulandari. As Environment Marine Foreman and an alumnus of Khairun University in Ternate, Wulan leads concrete steps for ecosystem recovery through mangrove planting, coral growth media installation, and regular sea quality monitoring in the Obi Industrial Area.
Ultimately, all these upstream-to-downstream safeguarding efforts are bound by one absolute foundation: a culture of compliance. At the PT Halmahera Jaya Ferronikel (HJF) smelting plant, this oversight is in the hands of Claudia Kowaas. As Occupational Health and Safety Compliance System Staff and an alumnus of Sam Ratulangi University, she ensures Occupational Safety and Health (K3) standards are truly implemented, not just stacks of administrative documents.
“Compliance is the absolute foundation. It is the lifeblood that ensures every worker can return home to their families safely,” emphasised Claudia.
The presence of women in these crucial operational positions at Harita Nickel is not an anomaly but a reflection of the new face of the mining industry. As noted by the Executive Director of the Indonesian Mining Association (IMA), Hendra Sinadia, the role of women in the mining sector is now developing rapidly, penetrating leadership levels.
At Harita Nickel, these heroines prove one thing: they are present not to fill quotas. They are decision-makers, nurturers of social harmony, risk mitigators, and the front-line guards ensuring all operational lines run in alignment with the company’s commitment to human development, nature preservation, and the welfare of the surrounding mining community.
