<p dir="ltr">The 2026 National Occupational Health and Safety (OHS) Month serves as a strategic momentum for Harita Nickel to reaffirm its collective commitment to strengthening a safety culture founded on connectivity and mutual responsibility. In alignment with the national theme, “Building a Professional, Reliable, and Collaborative National OHS Management Ecosystem,” Harita Nickel positions OHS not merely as a system, but as an integrated ecosystem embedded in the daily operations of all Insan Harita.</p>
<p dir="ltr">This commitment was reflected in the opening series of BK3N activities held across Harita Nickel’s operational areas on Obi Island, South Halmahera. The opening ceremony marked a unified declaration of commitment involving business units, management, and business partners, emphasizing that safety is a shared responsibility that must be implemented comprehensively and consistently.</p>
<p dir="ltr"><img style="display: block; margin-left: auto; margin-right: auto;" src="https://api.tbpnickel.com/storage/images/base64/page_1769993987_JlFGILezSA.jpeg" width="1080" height="720"></p>
<p dir="ltr">Deputy Technical Support of PT Obi Sinar Timur (OST), Amirrudin, stated that the principle of “Satu Harita, Saling Menjaga” extends beyond a tagline and must be internalized as a core value in every work activity. Safety, he noted, transcends organizational structures, functions, and roles, and is the responsibility of every individual as part of a single organization.</p>
<p dir="ltr">“Operational activities inherently involve potential hazards; however, incidents are preventable. Consistent adherence to procedures, compliance with OHS standards, and proactive care through mutual reminders are fundamental to establishing a safe working environment,” he explained.</p>
<p dir="ltr">He further emphasized that while management remains committed to providing adequate safety systems, procedures, training, and facilities, effective implementation is contingent upon the active participation and accountability of all Insan Harita.</p>
<p dir="ltr"><img style="display: block; margin-left: auto; margin-right: auto;" src="https://api.tbpnickel.com/storage/images/base64/page_1769993987_NqQlq1zq7l.jpeg"></p>
<p dir="ltr">In line with this, Primus Priyanto, Head of Mining Engineering at PT Trimegah Bangun Persada Tbk, underscored the importance of developing a professional, reliable, and collaborative OHS ecosystem. He noted that professionalism in OHS begins with a thorough understanding of occupational risks and is reinforced through consistent application of risk controls and strict compliance with work procedures.</p>
<p dir="ltr">“Professional conduct is demonstrated through consistency in adhering to work procedures and applying risk control measures,” Primus stated.</p>
<p dir="ltr">He added that the reliability of the OHS system must be continuously strengthened through the enhancement of human resource competencies and the reinforcement of the Mining Safety Management System (SMKP). This includes strengthening safety leadership, developing supervisory capabilities, and cultivating a constructive feedback culture that addresses unsafe actions or conditions as a form of care rather than blame.</p>
<p dir="ltr">“Feedback and corrective reminders should be viewed as an expression of concern for collective safety,” he emphasized.</p>
<p dir="ltr">Furthermore, Primus highlighted collaboration as a critical enabler of an effective OHS ecosystem. Cross-departmental involvement in setting OHS objectives, targets, and programs, supported by regular joint evaluations, is essential to ensure alignment and sustainability of OHS implementation across all operational areas.</p>
<p dir="ltr"><img style="display: block; margin-left: auto; margin-right: auto;" src="https://api.tbpnickel.com/storage/images/base64/page_1769993987_5lZDa7TlnB.jpeg"></p>
<p dir="ltr">Through the commemoration of BK3N 2026, Harita Nickel calls on all Insan Harita to embed safety as a core value, habitual practice, and organizational character. Returning home safely is not an option, but an obligation. Guided by the spirit of “Satu Harita, Saling Menjaga”, Harita Nickel remains committed to fostering a safe, healthy, and productive work environment while continuously strengthening the OHS management ecosystem.</p>

Satu Harita, Saling Menjaga: Harita Nickel Reinforces Its OHS Ecosystem

<p dir="ltr">Harita Nickel collaborated with the Kawasi Village Government to facilitate the formation of a Village Disaster Preparedness Team (TSBD). This initiative began with disaster preparedness training and simulations involving 51 residents in the New Settlement of Kawasi Village on Friday, December 19, 2025.</p>
<p dir="ltr">This activity was led by the South Halmahera Regional Disaster Management Agency (BPBD). It involved multi-stakeholder collaboration, ranging from the Oesman Sadik Meteorological Station, the Ternate Search and Rescue Office, the Auxiliary Health Center, to the Village Maternity Clinic. This cross-sector collaboration strengthens integrated and responsive disaster risk mitigation.</p>
<figure class="image align-center"><img src="https://api.tbpnickel.com/storage/images/base64/page_1768811330_NaIdNt59mW.jpeg" width="1080" height="720">
<figcaption><span style="font-size: 12px;"><em>Residents of Kawasi take part in an evacuation simulation as part of the formation of the Village Disaster Preparedness Team (TSBD).</em></span></figcaption>
</figure>
<p dir="ltr">Preparedness is a strategic necessity for Kawasi Village, located in a coastal area with potential for earthquakes and high rainfall intensity. Based on the Meteorology, Climatology, and Geophysics Agency (BMKG) monitoring, peak rainfall on Obi Island occurs in June, which has the potential to increase the risk of natural disasters. Therefore, 43 adults and 8 children participating in the training were provided with materials on risk identification, evacuation simulations, and strengthening coordination during emergencies.</p>
<p dir="ltr">The Head of the Welfare Section of Kawasi Village Government, Bambang Bakir, emphasized the importance of establishing the TSBD as a concrete step to improve community preparedness. "This training is important so that the community is ready to face the impacts of weather changes and potential natural disasters in Kawasi Village. The establishment of the Village Disaster Preparedness Team strengthens the role of residents as the main actors in preparedness," he said.</p>
<p dir="ltr">The Coordinator of Observation and Information at the Oesman Sadik South Halmahera Meteorological Station, Yusran Titdoy, added that preparedness must be based on data. "Disaster preparedness must be supported by accurate weather information. This year, the peak rainfall on Obi Island occurred in June. The BMKG is strengthening its monitoring so that the community can obtain early information on the potential impact of the weather," he explained.</p>
<p dir="ltr">This initiative is also in line with the spirit of Satu Harita, Saling Menjaga (One Harita, Looking After Each Other), and the Community Empowerment Program (PPM). Assistant Vice President of Site Corporate Communications at Harita Nickel, Joseph Sinaga, emphasized that the resilience of the community is the foundation of shared sustainability.</p>

Harita Nickel Supports TSBD Kawasi through Disaster Preparedness Training

<p dir="ltr" style="text-align: justify;">Behind its contribution to national development and economic growth, the mining industry carries inherently high occupational risks. Every worker in mining operations faces real hazards on a daily basis—from extreme working environments and the use of heavy machinery to exposure to materials that may be harmful to health.</p>
<p dir="ltr" style="text-align: justify;">Occupational Health and Safety (OHS) serves as the foundation for managing these risks and preventing workplace accidents and health-related incidents. Through an effective management system, potential hazards can be controlled — which is why OHS plays a crucial role in mining operations.</p>
<p dir="ltr" style="text-align: justify;">In this article, we will explore what OHS is, how it is applied within the mining industry, and how Harita Nickel integrates OHS as part of its identity and work culture across all operational lines.</p>
<h2 dir="ltr" style="text-align: justify;">What is OHS?</h2>
<p dir="ltr" style="text-align: justify;">OHS, which is known in Indonesia as K3 (Keselamatan dan Kesehatan Kerja), means Occupational Health and Safety in English. This term encompasses all policies, procedures, and efforts to protect workers from physical and psychological dangers, as well as from hazardous work environments.</p>
<p dir="ltr" style="text-align: justify;">In Indonesia, the legal basis for OHS implementation includes:</p>
<ul style="text-align: justify;">
<li dir="ltr" aria-level="1">
<p dir="ltr" role="presentation">Law Number 1 of 1970 concerning Occupational Safety, which outlines employer and employee obligations in ensuring workplace safety.</p>
</li>
<li dir="ltr" aria-level="1">
<p dir="ltr" role="presentation">Government Regulation Number 50 of 2012 concerning the Occupational Health and Safety Management System (SMK3).</p>
</li>
<li dir="ltr" aria-level="1">
<p dir="ltr" role="presentation">Minister of Energy and Mineral Resources Regulation Number 26 of 2018 concerning Good Mining Engineering Practices, which specifically regulates mining safety, occupational health, and environmental management.</p>
</li>
</ul>
<p dir="ltr" style="text-align: justify;">With these legal foundations, OHS is not merely a moral obligation or internal policy — it is a mandatory requirement that ensures companies maintain a safe and healthy working environment.</p>
<h2 dir="ltr" style="text-align: justify;">Why is OHS Essential in the Mining Industry?</h2>
<p dir="ltr" style="text-align: justify;">The mining industry has unique workplace characteristics, including heavy machinery use, remote operational areas, and rapidly changing geological and weather conditions. Several reasons make OHS critically important in this sector:</p>
<ul style="text-align: justify;">
<li dir="ltr" aria-level="1">
<p dir="ltr" role="presentation">Workers as main assets: Mining workers are at the frontline of operations and are key contributors to industrial success. Their safety and health must therefore be a top priority.</p>
</li>
<li dir="ltr" aria-level="1">
<p dir="ltr" role="presentation">High levels of hazards and risks: Activities such as mining, blasting, hauling, and mineral processing carry significant risks of accidents and occupational illnesses if not properly managed.</p>
</li>
<li dir="ltr" aria-level="1">
<p dir="ltr" role="presentation">Interaction between humans, equipment, and technology: Mining relies heavily on machinery and technological systems, yet human involvement remains decisive. This interaction can create safety risks if not carefully controlled.</p>
</li>
<li dir="ltr" aria-level="1">
<p dir="ltr" role="presentation">Operational sustainability: Modern mining companies are evaluated not only on production output, but also on how safely and responsibly they operate.</p>
</li>
<li dir="ltr" aria-level="1">
<p dir="ltr" role="presentation">Building a strong safety culture: Consistent implementation of OHS fosters a disciplined, collaborative, and caring work culture that supports long-term productivity and sustainability.</p>
</li>
</ul>
<h2 dir="ltr" style="text-align: justify;">Implementation of OHS at Harita Nickel</h2>
<p dir="ltr" style="text-align: justify;">Harita Nickel applies Occupational Health and Safety (OHS) as an integral part of all operational activities. This commitment is demonstrated through structured management systems, safety culture reinforcement, and strategic collaboration. Examples include:</p>
<p dir="ltr" style="text-align: justify;"><strong>a. International Management System Certifications</strong></p>
<p dir="ltr" style="text-align: justify; padding-left: 40px;">Harita Nickel has obtained ISO 14001:2015 and ISO 45001:2018 certifications, confirming that its environmental and occupational health and safety management systems meet international standards. This reflects the company's commitment to implementing best practices within its Integrated Management System.</p>
<p dir="ltr" style="text-align: justify;"><strong>b. Training and Capacity Building</strong></p>
<p dir="ltr" style="text-align: justify; padding-left: 40px;">Capacity building related to OHS is a priority at Harita Nickel, starting from safety induction to specialized internal training and competency development based on job functions. Knowledge and awareness of OHS are essential foundations for creating a strong safety culture. One example includes seminars and discussion forums conducted in collaboration with the University of Indonesia.</p>
<p dir="ltr" style="text-align: justify;"><strong>c. Strengthening Commitment and Awareness</strong></p>
<p dir="ltr" style="text-align: justify; padding-left: 40px;">Harita Nickel runs programs aimed at reinforcing corporate OHS commitment and increasing safety awareness across all business units. These efforts include hazard identification, routine inspections, safety standard implementation, and safety campaigns. The 2025 National OHS Month served as a momentum to disseminate safety messages widely and emphasize collective responsibility across the organization.</p>
<p dir="ltr" style="text-align: justify;"><strong>d. Strategic Collaboration and Continuous Improvement</strong></p>
<p dir="ltr" style="text-align: justify; padding-left: 40px;">Harita Nickel continuously collaborates with academic institutions to enhance scientific and technical approaches to OHS. In 2025, the company conducted a large-scale emergency response drill in collaboration with the Disaster Risk Reduction Center (DRRC) of the University of Indonesia, involving management teams, emergency units, employees, and government representatives.</p>
<p dir="ltr" style="text-align: justify;"><strong>e. Strengthening the Culture of “Safety is Everyone’s Role”</strong></p>
<p dir="ltr" style="text-align: justify; padding-left: 40px;">In daily operations, Harita Nickel emphasizes that OHS is not solely the responsibility of the Health, Safety &amp; Environment (HSE) function, but of every individual. OHS is embedded as a core company value aligned with the spirit of “Satu Harita, Saling Menjaga.” Practices such as reporting potential hazards, proper use of PPE, and self-inspection are part of daily work routines aligned with the philosophy that “working safely means going home safely.”</p>
<p dir="ltr" style="text-align: justify;">The implementation of OHS in the mining industry is not merely about regulatory compliance, but also about upholding human values, protecting lives, and ensuring operational continuity. Harita Nickel demonstrates that through a comprehensive approach ranging from international standards to daily work culture, Occupational Health and Safety can be embedded into the core values of a company.</p>
<p style="text-align: justify;">&nbsp;</p>
<p style="text-align: justify;">

What is OHS and Why is it a Cornerstone of Safety in the Mining Industry?

<p dir="ltr">As Indonesia's nickel industry grows stronger and downstreaming gains momentum, the need to develop and improve nickel smelter operating standards continues to increase. Harita Nickel, as an integrated nickel mining and processing company, emphasizes that national industrial growth must be accompanied by increasingly holistic occupational safety standards to ensure sustainable downstreaming.&nbsp;</p>
<p dir="ltr">This message was conveyed by Supriyanto Suwarno, Harita Nickel’s Operational Health and Safety (OHS) &amp; Management System Manager, during an exclusive discussion among nickel industry stakeholders held by the Indonesian Nickel Industry Forum (FINI) together with DSS Sustainable Solutions (dss+).</p>
<p dir="ltr">Through his presentation at the event titled "Transforming Indonesia's Smelting Industry," Supriyanto explained that the measures implemented by Harita Nickel to strengthen safety standards at the company's smelter refer to applicable regulations and reinforce a risk-based approach at the operational level.</p>
<p dir="ltr">"We implement a safety system that not only focuses on compliance, but also on a risk-based approach and strengthening the overall process. With increasingly complex smelter technology, safety must be managed in a measurable and comprehensive manner," he explained.</p>
<p dir="ltr">He added that safety reinforcement is built based on an integrated cross-functional OHS framework within the organization and involves stakeholders. Harita Nickel's OHS program covers three main aspects, namely operational activities, community, and stakeholders.</p>
<p dir="ltr">"The scope of our OHS program not only covers risk control in operational areas, but also the health and safety of the surrounding community, emergency management, and collaboration with stakeholders to maintain safety standards throughout the company's ecosystem," said Supriyanto.</p>
<p dir="ltr">Supriyanto concluded his presentation by emphasizing that the success of the smelter industry in Indonesia is highly dependent on strong partnerships and shared commitment among industry players, the government, industry associations, academics, the community, and global partners.&nbsp;</p>
<p dir="ltr">"Going forward, synergy with all stakeholders will be key in developing a well-standardized OHS framework. This begins with openness to knowledge sharing, strengthening safety regulations, and building local competencies so that Indonesia's smelter industry can grow with higher standards that are relevant to global needs," he concluded.</p>

<h1 style="text-align: justify;">Understanding Obi Island’s Environment: The Sea, Local Communities, and the Future of Indonesia’s Nickel Resources</h1>
<div style="text-align: justify;">The sea is the lifeblood of coastal communities in Obi Island, North Maluku. It serves as a source of livelihood, a nurturing environment for ecosystem growth, and a shared space where community life meets industrial activities. In recent years, the island has emerged as a focal point of attention amid intersecting interests, situated between the rising global demand for nickel to support the energy transition and growing public concern over its environmental impact.</div>
<div style="text-align: justify;">As different narratives continue to unfold, it is crucial to examine the state of Obi’s marine environment in its entirety. This article aims to provide a brief summary of the island’s ecological landscape, local communities, and environmental management, guided by routine monitoring, operational data, and the social dynamics observed on the ground.</div>
<div style="text-align: justify;">&nbsp;</div>
<h2 style="text-align: justify;">Coral Reefs and the “New Homes” on the Seafloor</h2>
<div style="text-align: justify;">Marine restoration has attracted significant focus as one of the key initiatives in environmental conservation. In several parts of Obi Island waters, hollow cube structures known as reef cubes have been deployed on the seafloor to help restore the ecosystem.</div>
<div style="text-align: justify;">Independent monitoring has recorded the following developments:</div>
<div style="text-align: justify;">• 109 species of coral reef fish from 22 families have been sighted within the restoration zone.</div>
<div style="text-align: justify;">• Coral growth rates between 0.93 and 6.64 cm over a two-year span.</div>
<div style="text-align: justify;">• The reef cubes have transformed into new habitat for species ranging from juvenile fish to adult groupers.</div>
<div style="text-align: justify;">The restoration is not intended to substitute natural processes; it is implemented incrementally with a measured approach to support ecological recovery.</div>
<div style="text-align: justify;">&nbsp;</div>
<h2 style="text-align: justify;">Water and Waste Management: Transparency and Control System</h2>
<div style="text-align: justify;">Water and waste management has always been one of the most discussed topics whenever mining activities come under public scrutiny. In Obi, several mechanisms work in parallel to preserve water quality and mitigate sedimentation risks.</div>
<h3 style="text-align: justify;">58 Settling Ponds to Mitigate Sedimentation</h3>
<div style="text-align: justify;">Runoff from the operational area is processed through 58 settling ponds to let sediment settle prior to release. This is a critical step to prevent solid particles from entering water bodies.</div>
<h3 style="text-align: justify;">Real-Time Monitoring through SPARING</h3>
<div style="text-align: justify;">Water quality is monitored automatically through the SPARING system (under the Ministry of Environment and Forestry). Data collected from the monitoring instruments are transmitted directly to the government’s data center, ensuring they can be audited at any time.</div>
<h3 style="text-align: justify;">Land-based Tailings Management, Zero Ocean Disposal</h3>
<div style="text-align: justify;">Harita Nickel does not implement the Deep-Sea Tailings Placement (DSTP) method. Instead, all tailings are processed through a Dry Stack Tailings Facility (DSTF):</div>
<div style="text-align: justify;">• Utilizes a dewatering-based system</div>
<div style="text-align: justify;">• Incorporates multiple protective layers</div>
<div style="text-align: justify;">• Designed to prevent seepage</div>
<h3 style="text-align: justify;">International-Standard Sustainability Audit</h3>
<div style="text-align: justify;">Harita Nickel undergoes the IRMA (Initiative for Responsible Mining Assurance) audit, a global mining standard comprising over 400 indicators. The audit involves independent verification, ensuring standardized practices and transparency in environmental management.</div>
<h2 style="text-align: justify;">Fishing Communities and the Coastal Economy: Indicators of Ocean Health&nbsp;</h2>
<div style="text-align: justify;">Ocean health extends beyond marine life and ecosystem; it is also reflected in the socioeconomic realities of coastal communities. Coastal fishing activities often serve as an early indicator of aquatic environmental change.</div>
<div style="text-align: justify;">Field observations report:</div>
<div style="text-align: justify;">• Unchanged fishing patterns; fishermen consistently follow their traditional fishing routes</div>
<div style="text-align: justify;">• Fish catch volumes (including commercially important species such as grouper, rabbitfish, and squid) remain stable</div>
<div style="text-align: justify;">• Effective marketing support through the SUTAN program, allowing tens of tons of fishermen’s catch reach the market&nbsp;</div>
<div style="text-align: justify;">The everyday practices of coastal communities are an integral part of Obi’s ecological balance, affirming the enduring role of the sea as their primary source of livelihood.</div>
<h2 style="text-align: justify;">Obi Island, Nickel, and the Future of Socio-Environmental System</h2>
<div style="text-align: justify;">Obi Island stands as one of the principal hubs of Indonesia’s nickel downstream industry. Despite its economic momentum, the island faces a significant challenge in balancing the rising global demands to advance the energy transition with the need to preserve the ecosystem and the well-being of coastal communities.</div>
<div style="text-align: justify;">The data and on-site observations reveal:</div>
<div style="text-align: justify;">
<ul>
<li>The productivity of Obi Island waters is well-preserved</li>
<li>Coral reef restoration outcomes show a sustained path to recovery</li>
<li>Tailings and water management adheres to international standards</li>
<li>Fishermen continue their everyday routines without any disruption</li>
</ul>
</div>
<div style="text-align: justify;">There is always room for improvement. The mining industry, anywhere in the world, requires rigorous supervision. In Obi, the current situation shows that processes of mitigation, monitoring, and recovery are actively underway.</div>
<div style="text-align: justify;">Ultimately, Obi Island is a connected ecosystem where marine life, communities, and industrial activities meet. Only by examining Obi in its complete, interconnected context can we gain a clearer, more balanced perspective on the future of Indonesia’s nickel industry.</div>
<div style="text-align: justify;">&nbsp;</div>

The State of Obi Island Waters and the Harita Nickel’s Environmental Management

<p dir="ltr">Harita Nickel, through PT Halmahera Jaya Feronikel (HJF), once again conducted a water pollution control drill to enhance the team's preparedness in responding to environmental emergencies. Through this annual exercise, the company reaffirms its commitment to maintaining water quality and complying with environmental management standards in its operational areas.</p>
<p dir="ltr">This drill focused on handling conditions when the water resulting from the treatment process showed parameters outside the quality standards. The activities carried out at the Wastewater Treatment Plant (WWTP) facility involved the Health, Safety, and Environment (HSE) team of PT HJF as the party responsible for managing domestic wastewater. This training was also part of fulfilling the ISO 14001 standard related to preparedness and emergency response systems.</p>
<p dir="ltr"><img style="display: block; margin-left: auto; margin-right: auto;" src="https://api.tbpnickel.com/storage/images/Media/Liputan/Kabar%20Obi/16112025_HN_PhotoDrillPengendalianPencemaranAirIPALP2HJF_51.jpg" alt="" width="1080" height="720"></p>
<p dir="ltr">The drill began with a scenario in which water quality test results showed that dissolved oxygen (DO) levels did not meet quality standards. The team then carried out a series of emergency response procedures to restore water quality parameters to normal.</p>
<p dir="ltr">Environment Superintendent of HJF, Bobby Loys Lengga, explained the steps taken by the team when the condition was discovered. "We verified our initial findings through testing at the outlet, and the results still showed DO outside the standard. After that, we contacted the wastewater treatment plant operator to immediately install a pump to help the air flow into the water (venturi pump) and repair the blower system," he said.</p>
<p dir="ltr">After corrective action was taken, the team conducted another test. The results showed that the DO value was back above the quality standard. Giovanni emphasized the importance of periodic exercises like this. "Preventive measures such as this ensure that the water discharged from the WWTP always meets quality standards before flowing into water bodies. In addition to preventing potential negative environmental impacts, this activity also educates the team on the importance of maintaining water quality," he added.</p>
<p dir="ltr"><img class="n1ed--selected" style="display: block; margin-left: auto; margin-right: auto;" src="https://api.tbpnickel.com/storage/images/Media/Liputan/Kabar%20Obi/16112025_HN_PhotoDrillPengendalianPencemaranAirIPALP2HJF_71.jpg" alt="" width="1080" height="720"></p>
<p dir="ltr">This water pollution control drill is one of three annual environmental drills conducted by the environment team, covering water, air, and hazardous waste management. All of the drills are designed to ensure preparedness and consistency in the implementation of standard operating procedures (SOPs) in the event of a potential emergency.</p>
<p dir="ltr">Through this training, Harita Nickel ensures that environmental monitoring and management in the company's operational areas continue to be conducted in accordance with established standards. This step also demonstrates the company's commitment to implementing responsible mining practices.</p>

Harita Nickel Conducts Water Quality Emergency Drill To Reinforce Pollution Control

<p dir="ltr" style="text-align: justify;">Harita Nickel operates nickel downstream facilities on Obi Island with the support of more than 23,000 workers. These massive operational activities and daily consumption generated high volumes of organic waste. If not managed properly, the waste can cause odors, produce methane gas, and has the potential to contaminate the soil and water around the operational area.</p>
<p dir="ltr" style="text-align: justify;">In response to this challenge, Harita Nickel developed KUSO (Kelola Ulang Sampah Organik or Organic Waste Management), an initiative by PT Trimegah Bangun Persada Tbk, aimed at transforming food waste into organic fertilizer as part of the implementation of circular economy principles on Obi Island.</p>
<p dir="ltr" style="text-align: justify;">Interestingly, the name ‘KUSO’ not only reflects the process of managing organic waste, but is also inspired by the endemic animal of Obi Island, the Obi cuscus (Phalanger rothschildi), which is known locally as kuso. This nocturnal marsupial symbolizes the harmony and the unique biodiversity of Obi, while also serving as a reminder that every environmental management effort is inherently linked to the preservation of life on the island.</p>
<p dir="ltr" style="text-align: justify;"><img style="display: block; margin-left: auto; margin-right: auto;" src="https://api.tbpnickel.com/storage/images/base64/page_1765872183_ZwLpPm8Yv4.jpeg" width="1080" height="720"></p>
<p dir="ltr" style="text-align: justify;">“Our KUSO program began in March 2024 with the processing of organic waste from the employee canteen. Now, this program is having a real impact, with a total of around 7.4 tonnes of organic waste that have been processed as of November 2025,” explained Imam Agus Faisyal, Junior Environment Compliance Engineer at PT TBP. He added that sorting waste at source is key to the success of composting at the CAKRA Composting House.&nbsp;</p>
<p dir="ltr" style="text-align: justify;">The CAKRA Compost House is a facility that processes food waste into compost through an organic process at the Harita Nickel site. The facility itself was chosen in line with the theme of the puppet (wayang) show, where "Cakra" symbolizes protection and balance. This philosophy is translated into a mission to restore the natural cycle by turning food waste into a new and useful resource.</p>
<p dir="ltr" style="text-align: justify;"><img style="display: block; margin-left: auto; margin-right: auto;" src="https://api.tbpnickel.com/storage/images/Media/Liputan/Kabar%20Obi/12122025_HN_KusoProductions_31.jpg" alt="" width="1080" height="720"></p>
<p dir="ltr" style="text-align: justify;">Upon arrival at the CAKRA Compost House, organic waste is chopped and mixed with wood chips or dry leaves to maintain a balanced carbon-nitrogen ratio. The mixture is then placed in a closed composter and treated with Miko Local Organism (MOL) as a bioactivator. This process is marked by rising temperatures inside the composter, reflecting active microbial decomposition.</p>
<p dir="ltr" style="text-align: justify;">“The composting process is carried out aerobically and requires regular turning to maintain oxygen flow and moisture,” said Imam.</p>
<p dir="ltr" style="text-align: justify;">As of November 2025, the CAKRA compost house has collected 7.4 tons of organic waste. Approximately 60% has been turned into around 4.4 tons of solid compost, while the liquid fertilizer produced ranges from 370 to 741 liters. All of these organic products are used for the maintenance of green spaces, nurseries, and reclamation in the company's operating areas.</p>
<p dir="ltr" style="text-align: justify;">PT TBP’s Senior Environment Compliance Engineer, M. Saifullah Nijar, emphasised that KUSO is the first step towards implementing more extensive organic waste management. “We hope that this program can be replicated independently in other business units, so that its benefits can be even greater,” he said.</p>
<p dir="ltr" style="text-align: justify;"><img style="display: block; margin-left: auto; margin-right: auto;" src="https://api.tbpnickel.com/storage/images/Media/Liputan/Kabar%20Obi/12122025_HN_KusoProductions_99.jpg" alt="" width="1080" height="720"></p>
<p dir="ltr" style="text-align: justify;">KUSO complements Harita Nickel's other circular economy initiatives, including the use of used bottles as biofilters in Wastewater Treatment Plants, the conversion of plastic waste into alternative fuel, and the use of used cooking oil as a substitute for coal in smelter facilities. This series of efforts underscores the company's commitment to reducing processing waste, strengthening resource efficiency, and maintaining environmental sustainability on Obi Island.</p>

KUSO: Harita Nickel's Solution to Transform Food Waste into Organic Fertiliser

<p dir="ltr">Amid the growing momentum of Indonesia’s nickel downstream industry, Harita Nickel on Obi Island, South Halmahera, demonstrates that industrial progress can go hand in hand with environmental care. For Dr. Tri Edhi Budhi Soesilo, M.Sc., Academician of the School of Environmental Science at Universitas Indonesia—who has visited Harita Nickel’s operations several times—this commitment is not mere rhetoric but a reality observed in the field.</p>
<p dir="ltr">“I see harmony between the upstream and downstream sectors, integrated seamlessly. From water to air management, everything is designed comprehensively and interconnected,” he said.</p>
<p dir="ltr">During his visit, Dr. Budhi highlighted four environmental innovations that, in his view, deserve to be models for the mining industry in Indonesia:</p>
<h3 dir="ltr" role="presentation"><strong>1. DSTF: A Tailings Management Innovation Worth Patenting</strong></h3>
<p><strong><img style="display: block; margin-left: auto; margin-right: auto;" src="https://api.tbpnickel.com/storage/images/Media/Liputan/Kabar%20Obi/17062025_HN_Universitas%20Indonesia%20%26%20Telapak%20Site%20Visit_229.jpg" alt="" width="1080" height="722"></strong></p>
<p dir="ltr" role="presentation">One of Harita Nickel’s major breakthroughs is the Dry Stack Tailing Facility (DSTF), a technology that manages Nickel Ore Processing Residue (SHP) by reducing its water content until it becomes solid. This method minimizes the risk of water contamination and enables wider reuse of materials for land reclamation.<br><br>“DSTF deserves to be patented. It’s not only technically sound but also demonstrates a strong commitment to sustainability,” said Dr. Budhi.</p>
<h3 dir="ltr" role="presentation"><strong>2. Research-Based Reclamation: Turning Slag into Fertile Planting Media</strong></h3>
<p><strong><img style="display: block; margin-left: auto; margin-right: auto;" src="https://api.tbpnickel.com/storage/images/Media/Liputan/Kabar%20Obi/17062025_HN_Universitas%20Indonesia%20%26%20Telapak%20Site%20Visit_47.jpg" alt="" width="1080" height="720"></strong></p>
<p dir="ltr" role="presentation">Harita Nickel has made significant strides in post-mining land rehabilitation. Going beyond administrative requirements, the company’s environmental team conducts experiments to find the most effective planting media composition.</p>
<p dir="ltr">Trials involve mixing overburden soil with nickel slag in various ratios to enhance the fertility of reclaimed land.<br><br>“This approach shows a willingness to learn and innovate. It’s not just a formal reclamation effort but an ongoing scientific process,” Dr. Budhi noted.</p>
<h3 dir="ltr" role="presentation"><strong>3. Protecting Kawasi Springs and Lake Karo: A Rapid Response System for Sustaining Life</strong></h3>
<p><strong><img class="n1ed--selected" style="display: block; margin-left: auto; margin-right: auto;" src="https://api.tbpnickel.com/storage/images/Media/Liputan/Kabar%20Obi/sorotan/23122025_Mata%20Air%20Kawasi_2.JPG" alt="" width="1680" height="1259"></strong></p>
<p dir="ltr" role="presentation">Water is a central focus in Harita Nickel’s environmental management. Every drop from mining areas undergoes treatment before being discharged back into the environment.</p>
<p dir="ltr">Monitoring at community water sources such as Kawasi Springs and Lake Karo consistently shows good and well-maintained water quality.<br><br>“I witnessed a very effective quick-response mechanism. Once a potential issue arises, all departments immediately coordinate to ensure the community isn’t affected. This is real accountability,” he emphasized.</p>
<h3 dir="ltr" role="presentation"><strong>4. 24-Hour Clean Air: Real-Time Emission Monitoring</strong></h3>
<p><img style="display: block; margin-left: auto; margin-right: auto;" src="https://api.tbpnickel.com/storage/images/Media/Liputan/Kabar%20Obi/dr-budhi-ui-site-visit.jpg" alt="" width="1080" height="721"></p>
<p dir="ltr" role="presentation">Beyond water and soil, air quality is also strictly monitored. Harita Nickel uses Electrostatic Precipitator (ESP) and Flue Gas Desulfurization (FGD) systems to reduce emissions from plant operations.</p>
<p dir="ltr">All air quality parameters are monitored in real time, 24 hours a day, with an automatic alarm system that activates if thresholds are exceeded.<br><br>“Emission control of this level is rarely seen in industrial operations. It reflects genuine corporate responsibility toward the environment and society,” said Dr. Budhi.</p>
<p dir="ltr">For Dr. Budhi, sustainability is not just about outcomes but about consistency in process. Routine documentation, cross-departmental collaboration, and a readiness to continually improve form the foundation of a responsible industry.</p>
<p dir="ltr">He concluded with a thoughtful reflection: “Nothing is ever perfect, but what I see here is sincerity. And from sincerity comes sustainable innovation.”</p>
<p dir="ltr">The harmony between industrial downstream development and environmental preservation, as reflected in Harita Nickel’s operations on Obi Island, stands as proof that the future of Indonesia’s nickel industry can—and should—be built upon the foundation of ecological responsibility and continuous innovation.</p>

Four Green Innovations by Harita Nickel Set an Example for the National Mining Industry

<p dir="ltr" style="text-align: justify;">Obi Island in North Maluku is known for one of the largest nickel mining operations in Indonesia, run by the Harita Nickel company. Due to the proximity of these operations to the coastline and offshore marine ecosystems, the quality of the seawater around the mine is a critical concern—not only for the company, but also for the local community, the environment, and stakeholders.</p>
<p dir="ltr" style="text-align: justify;">In this article, we take a closer look at the marine ecosystem surrounding Obi, and explore the environmental management efforts being implemented by Harita Nickel to ensure these habitats remain protected.</p>
<h2 dir="ltr" style="text-align: justify;">Marine Life and the Efforts to Protect It</h2>
<p dir="ltr" style="text-align: justify;">The marine ecosystem surrounding Obi Island supports many forms of life. Here, fishermen go out to sea, while fish take shelter among the reefs and corals grow on man-made frames. This scene is a picture of what Harita Nickel strives to preserve; healthy and productive waters, which can be passed down to future generations.</p>
<ul>
<li dir="ltr" style="text-align: left;"><strong>A Variety of fish and corals decorate the waters of Obi</strong><br>Monitoring of the restoration area has revealed the return of 109 species of reef fish from 22 families in the waters surrounding the artificial reef frameworks. These fish use these cube-like structures as a shelter and as their feeding grounds.</li>

These structures serve as a <a href="https://finance.detik.com/ekonomi-hijau/d-8057548/harita-nickel-sulap-sisa-hasil-pengolahan-jadi-rumah-buat-terumbu-karang?utm_source=chatgpt.com">“new home”</a> for coral growth.Over the past two years, observations have shown coral growth ranging from 0.93 cm to 6.64 cm. This is considered significant progress, as coral reefs typically require stable marine conditions and long growth periods. Clean seawater, adequate sunlight, and balanced temperatures are among the key factors supporting coral recovery.<br>Now, around these reef cubes, small fish and even groupers can often be found feeding among the young corals.</li>

<ul>
<li dir="ltr" style="text-align: justify;"><strong>Routine monitoring to maintain ocean quality<br></strong>Harita Nickel doesn't stop with the installation of reef cubes. The marine environment team conducts weekly maintenance, monitors coral growth, and records fish species. Every 6 months, seawater quality testing is also conducted with an&nbsp;<a href="https://tbpnickel.com/id/telapak-dan-unkhair-amati-laut-sekitar-harita-nickel-bersih-dan-terjaga">independent agency </a>for external verification.&nbsp;<br><img src="https://api.tbpnickel.com/storage/images/Media/Liputan/Kabar%20Obi/Lingkungan/A4.jpeg" alt="" width="600" height="337"><br><br></li>
<li><strong>Controlled mine water management<br></strong>To prevent direct sedimentation into the sea, Harita Nickel has built sediment ponds, large settling basins where water is directed so that soil sediments can settle before being released into river bodies. In addition, rainwater is collected and reused, as part of the company’s efforts to reduce dependence on limited freshwater sources. Meanwhile, residual materials from the HPAL (High Pressure Acid Leach) process are managed using the<a style="text-align: justify;" href="https://tbpnickel.com/id/tailing-bukan-beban-tapi-kesempatan-untuk-berkembang"> Dry Stack Tailings Facility (DSTF) method.</a><br><br><br></li>
<li><strong>Independent audits for transparency</strong><br>To ensure these practices meet the necessary standards, Harita Nickel is open to external audits, including <a href="https://connections.responsiblemining.net/site/266">IRMA (Initiative for Responsible Mining Assurance).</a> These audits assess environmental, social, and governance aspects, and provide recommendations for improvement.<br><br></li>

<p dir="ltr" style="text-align: justify;">The health of the ocean surrounding Obi Island is evident in the presence of reef fish, fishermen's catches, and positive reef growth. Harita Nickel continues to strive for sustainability through reef restoration, ocean quality monitoring, mine water management, and independent audits.</p>
<p dir="ltr" style="text-align: justify;">With the synergy of companies, communities, and the government, Obi Island can continue to be known not only for its nickel, but also for its rich and healthy sea.</p>

How Harita Nickel Protects Marine Biodiversity in the Obi Sea

<p dir="ltr" style="text-align: justify;">A recent study by researchers from the Faculty of Fisheries and Marine Sciences of Khairun University (FPIK Unkhair) Ternate shows that fishing activities on Obi Island continue to be active amid the development of the nickel mining and processing industry. This finding illustrates that coastal communities in Obi continue to adapt and be empowered in the midst of regional economic changes.</p>
<p dir="ltr" style="text-align: justify;">This research was conducted in June 2025, through observations and interviews with communities in Kawasi and Soligi Villages, two coastal villages that are in the operational circle of Harita Nickel.</p>
<p dir="ltr" style="text-align: justify;">Prof. Dr. Janib Achmad, S.Pi., M.Sc., Professor of FPIK Unkhair, said that observation is important to understand the socio-economic aspects of the community. "Fisheries are an important natural resource in South Halmahera, North Maluku. This observation is important to know the current condition of the company's presence on fisheries resources and coastal communities," he said.</p>
<p dir="ltr" style="text-align: justify;">The observation revealed that fishing activities in Kawasi and Soligi are still active. In Soligi Village, for example, there is a Tunas Mandiri fishermen group consisting of 16 full-time fishermen who are active at sea every day, and 59 part-time fishermen. Meanwhile, in Kawasi, there are 23 people who make a living as fishermen. The fish catch is quite abundant, with a variety of species.</p>
<p dir="ltr" style="text-align: justify;">"What fishermen in Soligi Village catch are tuna and skipjack. Tuna can reach 40 kg per trip, and skipjack up to 7 kg per trip. While in Kawasi Village, the types of fish caught are mackerel, caesio, trevally, grouper, and cockatoo," explained Dr. Nebuchadnezzar Akbar, S.Pi., M.Si., Researcher at the Faculty of Fisheries and Marine Sciences, Unkhair.</p>
<p dir="ltr" style="text-align: justify;">One of the fishermen from Soligi Village, Musahati, confirmed that fishing activities have continued and even become more supported since the collaboration with the company began.</p>
<p dir="ltr" style="text-align: justify;">“Before the company came, we sold our fish wherever we could. But often, part of our catch was rejected and sent back. After the company arrives, whenever there is a request — even for a small amount, like one ton or 200 kilograms — they take everything and pay immediately. So, automatically, our economy has improved,” said Musahati in an interview with academics from Unkhair and Telapak.</p>
<p dir="ltr" style="text-align: justify;">In addition to fishing activities, the observation of the research team from Unkhair also found Harita Nickel's initiative through Salam Kawasi, which succeeded in increasing the income of local fishermen by developing freshwater fish farming.</p>
<p dir="ltr" style="text-align: justify;">"Communities that previously relied solely on marine products have now also begun to develop freshwater fish farming businesses with tilapia and catfish. The results are sold to the company and the surrounding community," said Prof. Janib.</p>
<p dir="ltr" style="text-align: justify;">The observation of the Unkhair research team reported that coastal communities on Obi Island continue to adapt in the midst of industrial growth. Fishermen remain active at sea, while freshwater fish farming is an additional source of income.</p>
<p dir="ltr" style="text-align: justify;">The result of this observation confirms Harita Nickel's commitment to building open and constructive relationships with surrounding communities. The company also ensures that industrial progress can go hand in hand with improving the welfare of coastal communities.</p>
