Protecting Water Resources: Harita Nickel Collaborates With Communities in Kawasi Village

<h2 dir="ltr">Water, Mining, and Harita Nickel’s Commitment</h2>
<p dir="ltr" style="text-align: justify;">In mining activities, one of the most crucial environmental issues is water management. To ensure that water flowing from mining areas remains safe for the environment, Harita Nickel implements an integrated rainwater management system through the construction of sediment ponds. These facilities are located at several points across the mining area, including around Kawasi Village on Obi Island, North Maluku.<br><br></p>
<p dir="ltr" style="text-align: justify;">These sediment ponds demonstrate Harita Nickel's firm commitment to maintaining water quality, protecting the surrounding environment, and providing a sense of security for the surrounding community, particularly in Kawasi Village, which is located near to the operational area.</p>
<p dir="ltr">&nbsp;</p>
<h2 dir="ltr">What is a Sediment Pond and Why is it Important?</h2>
<p dir="ltr" style="text-align: justify;">A sediment pond, or settling pond, is a temporary holding pond that collects runoff from mining areas. In this pond, solid particles and sediments settle at the bottom, allowing the discharged water to become clearer and meet environmental quality standards.</p>
<p dir="ltr" style="text-align: justify;">The primary functions of a sediment pond include:</p>
<p dir="ltr" style="text-align: justify;">· &nbsp; Reduce Total Suspended Solids (TSS) levels to prevent water pollution.</p>
<p dir="ltr" style="text-align: justify;">· &nbsp; Maintain the quality of river and sea water, which are essential to daily life for local communities.</p>
<p dir="ltr" style="text-align: justify;">· &nbsp; Control runoff during the rainy season to prevent flooding or excessive turbidity in bodies of water.</p>
<p dir="ltr" style="text-align: justify;">&nbsp;</p>
<h2 dir="ltr">Scale and Capacity of Harita Nickel’s Sediment Ponds</h2>
<p dir="ltr"><img src="https://api.tbpnickel.com/storage/images/Media/Liputan/Kabar%20Obi/Lingkungan/B2.JPEG" alt="" width="900" height="506"></p>
<p dir="ltr" style="text-align: justify;">Harita Nickel builds its sediment ponds with carefully planned designs, taking into account the catchment area where water naturally flows. One example is<a href="https://tbpnickel.com/id/jaga-lingkungan-unit-bisnis-harita-nickel-berkolaborasi-kelola-air-2"> Tuguraci Pond 2</a>, which can accommodate water flows of up to 10,000–50,000 m³ per hour, which is especially important during periods of heavy rainfall.</p>
<p dir="ltr" style="text-align: justify;">Furthermore, Harita Nickel routinely adjusts the pond design and capacity to reflect the size of the catchment area being cleared. This means that each time new land is cleared, the pond system is expanded to accommodate the potential for rainwater runoff. This way, the risk of sediment overflow is minimized.</p>
<p dir="ltr">&nbsp;</p>
<h2 dir="ltr">Commitment to Water Management in Kawasi</h2>
<p dir="ltr"><img class="n1ed--selected" src="https://api.tbpnickel.com/storage/images/Media/Liputan/Kabar%20Obi/Lingkungan/B3.JPEG" alt="" width="900" height="600"></p>
<p dir="ltr" style="text-align: justify;">Kawasi Village is a key location for the implementation of this sediment pond system. As the area closest to mining operations, water quality in Kawasi must be strictly maintained. Harita Nickel ensures that any water flowing into the sea around Kawasi has undergone a strict filtration and sedimentation process in the sediment pond.</p>
<p dir="ltr" style="text-align: justify;">By taking these steps, Harita Nickel strives to ensure mining operations do not compromise environmental sustainability or the well-being of the Kawasi community.</p>
<p><strong>&nbsp;</strong></p>
<h2 dir="ltr">Part of Harita Nickel’s ESG Commitment</h2>
<p dir="ltr" style="text-align: justify;">The development and management of sediment ponds are part of Harita Nickel’s broader commitment to sustainability, ensuring a balance between environmental, social, and governance (ESG) principles.<br>By strengthening the application of these ESG values, Harita Nickel strives to make sure every aspect of its operations runs responsibly and transparently.</p>
<ul style="text-align: justify;">
<li dir="ltr" aria-level="1">
<p dir="ltr" role="presentation">Environmental: Protecting water quality and aquatic ecosystems.<br><br></p>
</li>
<li dir="ltr" aria-level="1">
<p dir="ltr" role="presentation">Social: Building and maintaining the trust of the Kawasi and Obi Island communities that mining activities are managed responsibly.<br><br></p>
</li>
<li dir="ltr" aria-level="1">
<p dir="ltr" role="presentation">Governance: Adhering to strict regulations on mine water quality and ensuring transparency in environmental management.<br><br></p>
</li>
</ul>
<p dir="ltr" style="text-align: justify;">In its <a href="https://api.tbpnickel.com/storage/images/TBP%20Sustainability%20Policy.pdf">sustainability report</a>, Harita Nickel highlights that water management is one of the company’s key pillars in sustainable mining practices.<br><br></p>
<p dir="ltr" style="text-align: justify;">The existence of sediment ponds in Kawasi and across the Obi Island mining area is a reflection of this commitment, showing how the company manages mine water responsibly in line with environmental regulations. With adaptive designs and supporting technology, Harita Nickel proves that mining operations can go hand in hand with efforts to protect the environment.Through integrated water management via sediment ponds, the company continues to ensure that the water quality around its mining areas, including in Kawasi, remains clean and well within environmental standards.</p><script src="https://cdn.flmngr.com/widgets.js?apiKey=FLMNFLMN" data-ts="1784619190385"></script>

Sediment Ponds: Harita Nickel’s Commitment to Mine Water Management

<p dir="ltr">Harita Nickel reaffirms its commitment to decarbonization and sustainable energy transition through its participation in the International Bangkok Climate Action Week (BKKCAW) 2025, held on September 28–29 in Bangkok. This international forum, themed “Renewable Energy and Mining Synergies in Indonesia,” brings together industry players, academics, and stakeholders to discuss the application of renewable energy and the challenges of decarbonization in the mining world.</p>
<p dir="ltr">Zahedi Zakaria, Harita Nickel's ESG Transformation Manager, presented Harita Nickel's concrete steps in its decarbonization efforts within its operational areas and the challenges involved.</p>
<p dir="ltr">"We operate on Obi Island, South Halmahera, about 200 km from the national power source, far from the energy hub, but we remain committed to consistently applying decarbonization principles. The challenges are great, but that's where innovation and collaboration come in," he said.</p>
<p dir="ltr">Various decarbonization efforts have been implemented by Harita Nickel, ranging from the construction of coal dome facilities to reduce dust, the installation of solar panels in office areas and worker dormitories, to the use of used cooking oil as an alternative fuel.</p>
<p dir="ltr">"Harita Nickel continues to develop decarbonization potential. Working with researchers and the government to support decarbonization targets, both at the operational level and at the national level," Zahedi added.</p>
<p dir="ltr">In addition to representatives from Harita Nickel, this discussion panel also featured Dr. Adji Kawigraha from BRIN, Fahmi Islami from Mandala Consulting, Dr. Muyi Yang from Ember Energy, and Dr. Rachel Zhou from Reach Advisory. The experts shared their insights on the application of renewable energy and the synergy among the mining sector in Indonesia.</p>
<p dir="ltr">Harita Nickel's participation in BKKCAW 2025 emphasizes the company's active role in supporting the global energy transition. Through strategic collaboration with all stakeholders, Harita Nickel is committed to continuing to develop sustainable solutions and strengthening its contribution to the achievement of Sustainable Development Goals (SDGs), particularly in the areas of clean energy and climate action.</p>

Harita Nickel Emphasizes Decarbonization and Renewable Energy in Bangkok Climate Action Week 2025

<p dir="ltr">A recent field visit by Perkumpulan Telapak, a non-governmental organization focused on environmental and social governance, together with a team of academics from Khairun University (Unkhair) Ternate, has confirmed that the marine ecosystem surrounding Harita Nickel’s operational area on Obi Island remains well-preserved and in good condition.</p>
<p dir="ltr">The joint team conducted observations at several points, including one located approximately 500 meters from the shoreline and another about five kilometers offshore. The results revealed clear seawater conditions, with artificial reefs developed from processed nickel slag showing natural coral growth.</p>
<p dir="ltr">According to Dickson Aritonang, Vice Chairman of Perkumpulan Telapak, the clarity of the surrounding waters reflects Harita Nickel’s strong environmental management performance.</p>
<p dir="ltr">“The water clarity is remarkable. Even at a depth of four to five meters, we could clearly see the artificial reefs developed by Harita Nickel already covered with naturally grown corals,” said Dickson, adding that the nickel slag-based reefs showed no signs of disrupting the surrounding marine ecosystem.</p>
<p dir="ltr">Dickson also observed the wastewater management infrastructure on land. He mentioned two main sediment ponds he observed, namely the Bunaken and Tuguraci ponds, covering approximately 20 and 40 hectares, respectively. Both are equipped with a Wastewater Treatment Plant (IPAL) and SPARING, a water quality monitoring tool directly connected to the Ministry of Environment.</p>
<p dir="ltr">"If the water quality isn't up to standard, the device will immediately send data to the Ministry. There's no grey area there," he explained. He assessed that the drainage and sedimentation system for mine runoff and wastewater at Harita Nickel demonstrates a solid oversight structure.</p>
<p dir="ltr">While acknowledging that mining activities have an impact, he emphasized the importance of appreciating the recovery measures. "Harita Nickel must remain open to independent evaluation. Because sustainability is not just about business performance, but also about social and environmental responsibility."</p>
<p dir="ltr">The findings of Dickson and the Telapak team align with the observations of the Unkhair academic team led directly by Prof. Dr. M. Janib Achmad, S.Pi., M.Sc. He also observed that Harita Nickel's operational activities are carried out with socially, economically, and environmentally responsible principles. "Observation results show that all the physical parameters of seawater we monitored meet quality standards. This indicates that the ecological pattern in the waters is maintained," he said.</p>
<p dir="ltr">Prof. Janib stressed the importance of using technology and implementing approaches oriented towards sustainable development. "These principles must continue to be upheld, so that the benefits truly reach the wider community, not just the industrial sector," he asserted.</p>
<p dir="ltr">Despite coming from different backgrounds, both Dickson Aritonang and Prof. Janib voiced the same common thread: environmental protection must be carried out with firmness, transparency, and oversight. And if this consistency is maintained, it is not impossible that what Harita Nickel is building on Obi Island today will become an important reference for more sustainable mining governance in the future.</p>

Telapak NGO and Unkhair Academics Confirm the Waters Around Harita Nickel Remain Well-Preserved

<p dir="ltr">Did you know? In 2024, Indonesia produced approximately 33.7 million tons of waste from 311 regencies/cities. Tragically, more than 40% of this waste is not managed properly. This situation is a wake-up call for us all. By following the principles of a more circular economy, we can begin to find solutions.</p>
<p dir="ltr">But what exactly does circularity mean in this context? What are its benefits? And how can we apply these approaches in our daily lives?</p>
<p dir="ltr">&nbsp;</p>
<h2 dir="ltr">What is the Definition of a Circular Economy?</h2>
<p dir="ltr">Circular economies follow a production and consumption model that aims to maintain the maximum value of products and materials for as long as possible through sharing, reusing, repairing, rejuvenating, and recycling the products and materials we use.&nbsp;Simply put, a circular economy encourages us to avoid wasteful patterns and shift to more resource-efficient ones.</p>
<p dir="ltr">This model is often summarized by the 3R principle:</p>
<p dir="ltr">· &nbsp; Reduce: Lessening the amount of waste created from the start.</p>
<p dir="ltr">· &nbsp; Reuse: Reusing items that are still in good condition by repairing or rejuvenating them.</p>
<p dir="ltr">· &nbsp; Recycle: Recycling items into new products with different functions</p>
<p dir="ltr">&nbsp;</p>
<h2 dir="ltr">Circular vs. Linear Economies</h2>
<p dir="ltr">A circular economy offers an alternative to the linear economic model we're more familiar with: Take, make, use, and dispose. In a linear economy, products are designed for limited use, encouraging consumers to continually purchase new ones.</p>
<p dir="ltr">By contrast, the circular economy seeks to break this wasteful cycle by creating a more sustainable system.</p>
<p dir="ltr">&nbsp;</p>
<h2 dir="ltr">Why Does it Matter?</h2>
<h3 dir="ltr">1. Protecting the Environment</h3>
<p dir="ltr">By reusing and recycling, we can use natural resources more responsibly and reduce greenhouse gas emissions that contribute to the climate crisis.</p>
<h3 dir="ltr">2. Encouraging Economic Efficiency</h3>
<p dir="ltr">Implementing the 3R principle also means we don't have to constantly buy new items. This is not only more economical but also opens up new business opportunities.</p>
<h2 dir="ltr">&nbsp;</h2>
<h2 dir="ltr">Circular Economy in Action at Harita Nickel</h2>
<p dir="ltr">So what about at Harita Nickel? Here, the circular economy isn’t just a concept, but real-life practice that is implemented on a daily basis. We continue innovating on Obi Island, to make our operations more environmentally friendly and efficient.</p>
<p dir="ltr">Here are some of the initiatives we've implemented so far:</p>
<h3 dir="ltr">1. Plastic Waste Reduction</h3>
<p dir="ltr">We initiated the #AwalBaikDariObi movement in 2024 as a first step to reduce the use of single-use plastics on site. This movement was fully supported by management through the signing of a joint commitment, which became an official company policy.</p>
<h3 dir="ltr">2. Nickel Slag Utilization</h3>
<p dir="ltr">Nickel slag, a byproduct of the processing of saprolite ore into ferronickel, is usually considered waste. However, at Harita Nickel, slag is utilized optimally.&nbsp;With its sand-like texture, this slag is reused for various construction needs, from dormitories, offices, and to developing road infrastructure within the operational area.</p>
<h3 dir="ltr">3. Used Cooking Oil Utilization</h3>
<p dir="ltr">We also utilize used cooking oil from employee consumption as an alternative fuel to coal in the ferronickel smelter.&nbsp;The result? This process is capable of generating 1,545 GJ of energy while preventing more than 1,419 tons of greenhouse gas emissions (CO₂ equivalent).&nbsp; A simple step, with a big impact.</p>
<p dir="ltr">&nbsp;</p>
<p dir="ltr">The circular economy isn't just a future concept—it's a necessity today. By implementing it, we can live more sustainably, economically, and environmentally consciously.&nbsp;And most importantly: Every small step, like the ones we're taking at Harita Nickel, has the potential to make a huge difference!</p>

Circular Economy: Definition, Benefits, and Examples of Application

<p dir="ltr">As a home for marine biodiversity, coral reefs are an important part of the ecosystem around Obi Island, South Halmahera. Recognizing this, Harita Nickel presents the reefcube innovation, an artificial, modular-shaped coral reef made from nickel processing byproducts in the form of fly ash and nickel slag.</p>
<p dir="ltr">Interestingly, despite being made from nickel processing by-products, nickel slag is considered non-B3 waste or non-hazardous and toxic material. Based on characteristic tests, this material is not toxic, making it safe to use in the sea. Instead, the minerals in it support the growth of corals and marine life.</p>
<p dir="ltr">Multi-year study by Harita Nickel’s Environment Team published in the <a href="https://jurnal.usk.ac.id/depik/article/view/46932/pdf">DEPIK journal from Syiah Kuala University Aceh</a>&nbsp;with the title "Coral Recruitment Enhancement in Fish Shelter Media Composed of Fly Ash and Nickel Slag on Obi Island, South Halmahera", shows that reefcube is effective for coral recruitment process, which is the process of coral larvae (planula) attaching to a surface and grows into a new colony.&nbsp;</p>
<p dir="ltr">Windy Prayogo, Harita Nickel’s Environmental Marine Compliance Manager, explained that they have produced reefcubes since 2020, deployed 1,696 units, and continue to monitor their effectiveness. “We conduct regular monitoring to record the development of the reefcubes that we have placed, including natural coral growth,” he explained.</p>
<p dir="ltr">The results of a two-year observation showed that coral growth in reefcubes reached 2.4–12.9 centimeters, particularly in the genera Isopora and Pocillopora. Beyond coral growth, the reefcube also successfully attracted 128 species of reef fish and other marine animals, turning it into a lively artificial ecosystem.</p>
<p dir="ltr">The result of this study also shows that the reefcube produced with fly ash and nickel slag provides a strong foundation for the successful coral recruitment process, creating new habitats for marine biodiversity on Obi Island. When responsibly processed, the byproducts from nickel processing can positively impact the marine environment of Obi.</p>
<figure class="image"><img src="https://api.tbpnickel.com/storage/images/25012025_KPS_Slag%20Nickel_12.jpg" alt="Nickel slag used as the main material for reefcube, Harita Nickel’s artificial coral reef innovation in the waters of Obi Island.">
<figcaption>
<p><span style="font-size: 12px;"><em>Nickel slag used as the main material for reefcube, Harita Nickel’s artificial coral reef innovation in the waters of Obi Island.</em></span></p>
</figcaption>
</figure>
<p dir="ltr">"Reefcube has proven to be effective as a coral recruitment medium because it is made from fly ash and nickel slag, which are rich in calcium, magnesium, and silica. When submerged, these minerals create ideal conditions for coral larvae to attach and grow," said Prasari Riski Hutami, Marine Monitoring Team Diver, Harita Nickel Environment Department.</p>
<p dir="ltr">More than a technical solution, the reefcube demonstrates that mining practices can work in synergy with marine conservation efforts. Nickel slag no longer ends up as waste material, but takes on a new role in supporting marine biodiversity, particularly on Obi Island. This initiative shows that nickel slag, when processed wisely, can become a new foundation for aquatic biodiversity. A testament to Harita Nickel’s commitment to sustainability.</p>

Harita Nickel Boosts Coral Growth with Reefcube Made from Nickel Slag

<p dir="ltr" style="text-align: justify;">Have you ever wondered what happens to land after it’s been mined? Is it just left alone?</p>
<p dir="ltr" style="text-align: justify;">Naturally, the answer is no. Mining companies are required to undertake reclamation activities to restore the environment after it's been used. But what exactly is reclamation? Can it really restore nature to its former glory? Let’s take a closer look!</p>
<h2 dir="ltr" style="text-align: justify;">What is Mine Reclamation?</h2>
<p dir="ltr" style="text-align: justify;">Mine reclamation is an activity that’s done throughout the mining business cycle, in order to organize, restore, and improve the quality of the environment and ecosystem so that it can function properly again.</p>
<p dir="ltr" style="text-align: justify;">Reclamation is a mandatory requirement for mining companies, as stipulated in<a href="https://peraturan.bpk.go.id/Details/138909/uu-no-3-tahun-2020"> Law Number 3 of 2020 concerning Mineral and Coal Mining (Minerba Law).</a></p>
<p dir="ltr" style="text-align: justify;">In fact, this regulation states that companies are required to submit a reclamation plan, even before they begin their operations!</p>
<h2 dir="ltr" style="text-align: justify;">Objectives of Mine Reclamation</h2>
<p dir="ltr" style="text-align: justify;">The primary goal of reclaiming former mining sites is to ensure that the land can be used again for its original purpose. More specifically, reclamation has several main objectives:</p>
<p dir="ltr" style="text-align: justify;">a. Restore the ecosystem, by replanting suitable vegetation so that the habitats of wildlife affected by mining activities can also be restored;</p>
<p dir="ltr" style="text-align: justify;">b. Prevent environmental damage such as erosion, landslides, and pollution; and</p>
<p dir="ltr" style="text-align: justify;">c. Support economic sustainability as the former mining land is restored.</p>
<h2 dir="ltr" style="text-align: justify;">The Mine Reclamation Process&nbsp;</h2>
<h3 dir="ltr" style="text-align: justify;">1. Planning</h3>
<p dir="ltr" style="text-align: justify;">Before a mine commences operations, the company is required to develop a 5-year reclamation plan for the mining site. This plan must be approved by the government before a permit is issued.</p>
<h3 dir="ltr" style="text-align: justify;">2. Implementation</h3>
<p dir="ltr" style="text-align: justify;">Reclamation can generally be divided into three stages:</p>
<ul>
<li dir="ltr" style="text-align: justify;">
<h4>Land Preparation</h4>
</li>
</ul>
<p dir="ltr" style="text-align: justify;">Formerly mined lands need to be reshaped and stabilized, for example by creating a safe slope. After that, fertile topsoil–which is collected during mining–is spread to allow plants to grow well.</p>
<p dir="ltr" style="text-align: justify;">Finally, infrastructure is put in place to control erosion and sedimentation. Some common methods include drainage, drop structures, sediment ponds, permanent drainage, sediment traps, and the use of cover crops.</p>
<ul>
<li dir="ltr" style="text-align: justify;">
<h4>Revegetation</h4>
</li>
</ul>
<p dir="ltr" style="text-align: justify;">This stage begins with planting cover crops. Good cover crops meet several criteria, including ease of planting, rapid growth, dense growth, symbiosis with beneficial bacteria or fungi, abundant biomass production, and rapid decomposition.</p>
<p dir="ltr" style="text-align: justify;">Cover crops play a crucial role in successful reclamation because they prevent erosion, enrich the soil, accelerate weathering, and suppress weed growth.</p>
<p dir="ltr" style="text-align: justify;">Next is the planting of pioneer plants. Pioneer plants are usually chosen because they grow quickly and adapt quickly to environmental conditions. Some plants often used for this purpose are gamal (Glycine gliricidia), lamtoro (Leucaena lamtoro), sengon laut (Sea falcataria), turi (Turi bean), johar (Johar), etc.</p>
<p dir="ltr" style="text-align: justify;">If the pioneer plants grow well, local plants are also planted, to enrich plant biodiversity.</p>
<ul>
<li dir="ltr" style="text-align: justify;">
<h4>Maintenance</h4>
</li>
</ul>
<p dir="ltr" style="text-align: justify;">Along with planting, maintenance is carried out in the form of fertilization, replanting, and weeding. In addition, weeds are removed, and diseases affecting the reclaimed plants are treated.</p>
<h2 dir="ltr" style="text-align: justify;">Harita Nickel: An Example of Mining Reclamation</h2>
<p><img class="n1ed--selected" src="https://api.tbpnickel.com/storage/images/Media/Liputan/Kabar%20Obi/Lingkungan/Aerial_Sunrise%20Reklamasi_2010202317.jpg_compressed.JPEG" alt="Aerial Reklamasi" width="1008" height="566"></p>
<p dir="ltr" style="text-align: justify;">Since before mining operations began, Harita Nickel has been developing a detailed plan to restore the native ecosystem. As of 2024, we have successfully revegetated an area of ​​231.53 hectares.</p>
<p dir="ltr" style="text-align: justify;">In the revegetated area, we are propagating seedlings of local tree species, including nani, bintangur, rain, mersawa, gosale, and cashew. We also regularly maintain the revegetated area.</p>
<p dir="ltr" style="text-align: justify;">Moreover, on January 30, 2025, Harita Nickel revegetated and inaugurated the Loji Central Nursery, a modern 2.8-hectare nursery with a capacity of up to 400,000 tree seedlings per year. These seedlings are used to expedite the reclamation process and support ecosystem recovery in areas surrounding the mine.</p>
<p dir="ltr" style="text-align: justify;">Harita Nickel is committed to continually reclaiming ex-mining land and monitoring the progress of the reclamation area to ensure it continues to provide a healthy habitat for the flora and fauna of Obi!</p>

World Cleanup Day Unites Harita Nickel and Obi Community in Joint Environmental Action

<p dir="ltr" style="text-align: justify;">Harita Nickel is advancing its commitment to renewable energy, with one of its key initiatives being the construction of a rooftop solar power plant (PLTS) on its office facilities and employee accommodations.</p>
<p dir="ltr" style="text-align: justify;">Low-emission energy is no longer a choice but a necessity. The world demands concrete steps to reduce carbon emissions, and Indonesia has affirmed its commitment to achieving net-zero emissions by 2060 or sooner. The industrial sector, including nickel mining and processing, plays a crucial role in this achievement.</p>
<p dir="ltr" style="text-align: justify;">Harita Nickel recognizes this responsibility. As an integrated mining and downstream processing company on Obi Island, Harita Nickel sees its role as extending beyond just the production process. Besides its use in stainless steel, the nickel produced here is an essential raw material for electric vehicle batteries, which are the backbone of the future's clean energy.</p>
<p dir="ltr" style="text-align: justify;">The energy demand for nickel mining and processing operations is substantial, and historically, it has been largely dependent on coal.</p>
<p dir="ltr" style="text-align: justify;"><img src="https://api.tbpnickel.com/storage/images/Media/Liputan/Kabar%20Obi/Lingkungan/PLTS%203.jpg" alt="" width="971" height="647"></p>
<p dir="ltr" style="text-align: justify;">To address this challenge, Harita Nickel has begun developing several solar power plants (PLTS) across various facilities, including at employee dormitories (pilot project, soon to be operational), at the facilities of PT Halmahera Persada Lygend (HPL), PT Obi Nickel Cobalt (ONC), and at the Nickel Sulfate plant, as well as in the HJF area (currently under construction, with the largest capacity in the first phase).</p>
<p dir="ltr" style="text-align: justify;">"The utilization of PLTS in the Obi Industrial Area (KIO) is a tangible step to accelerate the energy transition in the mining sector. Besides supporting operational efficiency, this initiative is also in line with global renewable energy trends and our national net-zero emission target," said Amiruddin, Deputy Department Head of Technical Support at PT Obi Sinar Timur (OST), the energy operator in KIO.</p>
<p dir="ltr" style="text-align: justify;">Although still in the early stages, the use of these solar panels is expected to have a significant impact by reducing the company's dependence on fossil fuels and simultaneously creating opportunities for future energy efficiency. Harita Nickel aims to gradually achieve an installed capacity of up to 300 MWp.</p>
<p dir="ltr" style="text-align: justify;"><img src="https://api.tbpnickel.com/storage/images/Media/Liputan/Kabar%20Obi/Lingkungan/PLTS%202.jpg" alt="" width="968" height="645"></p>
<p dir="ltr" style="text-align: justify;">Tonny Gultom, Director of Health, Safety &amp; Environment (HSE) at Harita Nickel, explained that the development of solar power plants (PLTS) requires a significant investment.</p>
<p dir="ltr" style="text-align: justify;">"This investment is certainly not cheap, but it is crucial for low-emission operations," Tonny emphasized.</p>
<p dir="ltr" style="text-align: justify;">All of these initiatives are part of Harita Nickel's decarbonization roadmap. The company seeks to demonstrate that business growth and sustainability can go hand-in-hand. For Harita Nickel, the use of PLTS on Obi is not merely a technical step but a strategic foundation for a low-carbon future for the Indonesian nickel industry.</p>
