</figure>
Harita Nickel's Vice President of OHS &amp; Management System, Supriyanto Suwarno, said the exercise was designed based on the characteristics of the company's operational area and evaluations of previous exercises. Potential emergencies may arise from both operational activities and natural hazards, making it essential to continuously strengthen personnel readiness and community support.
“In an emergency, no party can act alone. Everyone needs to work together to ensure an effective response,” he said.
This year's exercise involved approximately 1,500 personnel undertaking various roles, from planning and management to incident control and evacuation. The scenarios covered potential emergencies arising from natural disasters and operational incidents, with a focus on landslide-prone areas, residential settlements and power generation facilities. The exercise also took into account developments in the operational area, including newly established facilities that had not been covered in previous drills.
Head of Prevention and Preparedness at the South Halmahera Regional Disaster Management Agency (BPBD), Riski Triandini ASM, ST, highlighted the importance of such exercises in ensuring that personnel understand their respective procedures and responsibilities during emergencies. He also noted improvements in participants' understanding compared with the previous year's exercise.
“Exercises like this help test procedures while familiarising personnel with the appropriate responses, enabling them to act quickly and effectively without panicking,” he said.
According to Riski, regular exercises are essential to maintaining these capabilities. Community preparedness also deserves attention, as residents living near operational areas may be directly affected when a disaster occurs.
In Kawasi Village, community involvement has been further strengthened through the establishment of the Village Disaster Preparedness Team (Tim Siaga Bencana Desa or TSBD). Kawasi Village Secretary Frans Datang welcomed the LSE, noting that it provided residents with an opportunity to better understand the steps they should take in an emergency.
Yunince, one of the residents who participated in the exercise, expressed hope that similar activities would be held regularly to help the community become more familiar with emergency response and self-evacuation procedures.
“I hope exercises like this can be held every year so that residents always remember what to do when a disaster occurs,” she said.

Harita Nickel Presents Nickel Slag Innovation for Mine Reclamation at IPB University

Five students from SMA Negeri 10 Surabaya have won a gold medal at Indonesia Inventors Day (IID) 2026 for research exploring the potential use of nickel slag as a plant-growing medium. The achievement follows their earlier gold-medal success at the 2026 ASEAN Innovative Science Environmental and Entrepreneur Fair (AISEEF), highlighting their continued interest in the potential applications of nickel slag.
Their latest research, titled LESAGO: The Use of Legume Cover Crops in Nickel Slag-Based Growing Media on Plant Growth with an Expansive Root System, examines plant growth in nickel slag-based media combined with legume cover crops. The students are exploring how this approach could contribute to research into land revegetation.
<figure class="image"><img style="width: auto; height: auto;" src="https://api.tbpnickel.com/storage/images/WhatsApp%20Image%202026-10-07%20at%2011.15.26_1.jpeg" alt="SMA Negeri 10 Surabaya’s gold medal at Indonesia Inventors Day 2026 highlights how industry experience can inspire young innovators." width="4032" height="2268" data-fm="true">
<figcaption>SMA Negeri 10 Surabaya’s gold medal at Indonesia Inventors Day 2026 highlights how industry experience can inspire young innovators.</figcaption>
</figure>
Organised by the Indonesian Invention and Innovation Promotion Association (INNOPA), IID 2026 took place from 3 to 6 October at the SMESCO Building in Jakarta. The event brought together students and innovators from various countries to present their research and innovations.
The team's success builds on its earlier achievement at AISEEF 2026, held at Diponegoro University, where it also won gold for NISAGO: Utilization of Nickel Slag as a Planting Medium on Soil Properties and Growth Response of Ipomoea aquatica. Together, the two projects reflect the students' continued exploration of nickel slag and its potential applications in plant cultivation.
The idea behind LESAGO grew from the students' interest in industrial process residues and their potential role in revegetation. Environmental management practices in Obi's nickel industrial area provided a context for their inquiry, prompting them to explore how materials generated by industrial processes might have applications beyond their original purpose.
“We were initially interested in exploring how nickel slag could be put to use rather than simply being treated as industrial waste. This led us to investigate its potential as a planting medium and how it could be combined with cover crops to support revegetation,” said Abid Hakim Pradana, head of the SMA Negeri 10 Surabaya research team.
<figure class="image"><img style="width: auto; height: auto;" src="https://api.tbpnickel.com/storage/images/IMG-20261009-WA0054.jpg.jpeg" alt="SMA Negeri 10 Surabaya’s student research team had previously won gold at AISEEF 2026 for their NISAGO research, ahead of their success at IID 2026." width="4032" height="3024">

From Obi to the International Stage, Surabaya Students Win Gold for Nickel Slag Research

Harita Nickel continues to advance its approach to managing processing residues (SHP) as part of its commitment to responsible operations. What was once focused primarily on meeting regulatory requirements has evolved into efforts to find ways to reuse and create value from materials generated during the production process.
This was the key message conveyed at the *Integrated Waste and Residue Management and Environmental Quality Control Workshop*, held in Jakarta on Thursday, 3 September. The forum brought together Harita Nickel’s Health, Safety, and Environment (HSE) team and the Ministry of Environment / Environmental Control Agency (KLH/BPLH). During the event, Harita Nickel presented its circular economy innovations and received direct input and guidance from the regulator.
The workshop opened with remarks from Tonny H. Gultom, HSE Director of Harita Nickel, who emphasized that processing residue management is a strategic priority for the company. He also highlighted Harita Nickel’s continued efforts to encourage innovation in finding ways to reuse these materials.
Representing KLH, Drs. Sayid Muhadhar, M.Si., Director of Pollution and Environmental Damage Control in Coastal and Marine Areas at KLH/BPLH, stressed the importance of open communication between the government and industry. He also highlighted the role of appropriate environmental quality monitoring instruments, including SPARING, in ensuring that environmental performance data can be measured and properly accounted for.
The forum continued with opening remarks from Iwan Syahroni, Executive Vice President of Environmental Affairs at Harita. “Processing residue management on Obi Island is carried out based on circular economy principles. Through this approach, materials that were previously considered unusable can be put to use and given economic value,” Iwan explained.
Circular Innovations in Processing Residue Utilization
The session then moved to a presentation on Harita Nickel’s integrated processing residue management roadmap. Since 2017, the company has established controlled disposal systems in former mining areas. It subsequently expanded its dry tailings storage facilities while gradually developing innovations to shift its focus from controlled storage toward material utilization.
“Our plant capacity continues to grow, which also means an increase in the volume of processing residues. That is why we continue to innovate, so that former mining areas and the materials generated from our operations can regain their value,” said Aladin Sianipar, Vice President of Sustainable Product Development at Harita Nickel.
One type of processing residue that has found potential for reuse is *dry tailings*. Based on characterization tests, this material, generated from the processing of nickel limonite through the high-pressure acid leaching (HPAL) method, contains more than 43% iron.
This composition opens up two potential applications currently being developed by the company. The first is the production of *iron oxide pigment* for the ceramics industry, which has already been applied in paving block products used in operational areas. The second is the production of ferrous sulfate (FeSO₄), which can support water treatment processes. Its potential application is also supported by laboratory testing conducted in collaboration with the Bandung Institute of Technology (ITB).
Circular economy principles have also been applied to nickel slag products. Generated through the Rotary Kiln-Electric Furnace (RKEF) process, this material has been utilized by the company as a raw material for concrete bricks and as a soil amendment in reclamation activities, in accordance with SNI 9420:2025.
A similar approach is applied to domestic waste management. In the company’s operational areas on Obi Island, two Integrated Waste Processing Facilities (TPST) are in operation. Harita Nickel uses these facilities to implement technology-based waste sorting through magnetic separation, composting, odor control, and leachate treatment. These efforts focus on recovering and reusing materials, including converting waste into organic fertilizer and materials for fuel mixtures or construction products.
From Waste Management to Resource Management
Amsor, S.T., Director of Hazardous and Non-Hazardous Waste Management at KLH, also attended the forum. Responding to Harita Nickel’s presentation, he explained that waste is generated by all industrial activities, not only mining. However, industrial players must continue to take environmental considerations into account. This is where the circular economy can play a role.
“We appreciate the innovations presented by Harita Nickel. They represent one of the efforts to address existing challenges. The Minister’s direction is to ensure that every business activity generates benefits, with a portion of those benefits also allocated to the environment. Efforts like these are positive and should continue, while maintaining due consideration for environmental aspects,” Amsor explained.
Harita Nickel continues to support stronger collaboration between industry and regulators. This discussion forum reflects the company’s efforts to ensure that every initiative to utilize processing residues remains aligned with applicable regulations and can be implemented responsibly, with a continued commitment to improvement.<script src="https://cdn.n1ed.com/widgets.js?apiKey=FLMNFLMN" data-ts="1794281438487"></script>

PIC of the 2026 Carnival Festival, Ryan Monginsidi, said the event is an annual program that consistently provides employees with a space to showcase their ideas.
“The carnival is an annual event organized by PT Trimegah Bangun Persada and one of the most unique platforms, where employees can showcase their creative ideas through costumes, dance, and music,” Ryan said.
One of the standout concepts came from the Human Resource and General Affairs (HRGA) team through its theme, “The Civilization of the World.” The concept took the audience on a journey through human civilization, from traditional life in the past to modernization and the age of technology. Human Resource and General Affairs Foreman at Harita Nickel, Arthur Siwi, said the concept was inspired by the development of human civilization from the past to the modern era.
“Through this concept, the story we wanted to convey is that Obi Island is part of the journey of world civilization. Through the downstream processing of nickel ore, Obi is now connected to the world and has become part of the development of the global industry,” Arthur added.
The idea was brought to life through costumes, music, movement, and visual elements. The combination earned the HRGA team a place among the top three winners of the 2026 Carnival Festival.
Behind the achievement was a process that was equally meaningful. Team members exchanged ideas, shared responsibilities, and practiced together to build a strong sense of teamwork. These moments made the carnival more than just a performance; they became part of the shared experience of Insan Harita.

Harita Nickel Operations Director, Younsel Evand Roos, hopes that the spirit behind the Carnival Festival will continue to grow.
“I hope the Carnival Festival will not only serve as a place for Insan Harita to express their creativity and ideas, but also as a space to strengthen the bonds of togetherness among employees,” Younsel said.
With 17 teams taking part, the 2026 Carnival Festival became a celebration that brought different stories together on one stage. Through every concept and performance, Insan Harita showed how interests, talents, and a spirit of togetherness can come together in one meaningful moment.
From Kawasi, we embrace the world. Not only through the creativity showcased on stage, but also through the spirit of Insan Harita to keep creating, collaborating, and supporting one another. Let the spirit of the Carnival Festival continue in our daily lives, as we keep creating, keep collaborating, and together build positive energy in the spirit of “One Harita, Looking Out for One Another.”

One Stage, Many Stories: The Spirit of Insan Harita at the 2026 Carnival Festival

Amid a prolonged dry season and unpredictable weather, the Millennial Farmers’ Group in Buton Village, Obi District, has achieved a rice yield of at least 6.5 tonnes per hectare, exceeding the national target of 5.7 tonnes per hectare.
The harvest covered 12.5 hectares of farmland and was part of the “Synergy to Build the Nation” Rice Harvest Festival held on Monday (7 September). The event brought together South Halmahera Agriculture Agency Head Suryatmi Aldjokja, representatives of the Obi Agricultural Extension Centre (BPP), the sub-district leadership coordination forum (Forkopincam), and village government representatives.
Based on crop-cutting sample results conducted by the field support team, yields reached at least 6.5 tonnes per hectare across several varieties, including Inpari, upland rice and Mentik Wangi. The harvest marked the first for the Millennial Farmers’ Group, which was established earlier this year.
Group Head Ruslan Kasman said the achievement came despite challenging weather conditions. The group’s initial planting was lost after heavy rainfall, while replanting was followed by a prolonged dry season.
“We almost gave up. We are grateful for the continued support from the government and the company, including assistance with irrigation, which has helped ensure a steady water supply,” Ruslan said.
Suryatmi said the first harvest demonstrated the group’s rapid progress while contributing to food security efforts in South Halmahera. She said agricultural development is aligned with the South Halmahera Government’s Agromaritime concept, which integrates the region’s agricultural, marine and fisheries potential in a coordinated and sustainable manner.
“Support and collaboration from various stakeholders, including the private sector, are essential. We are committed to improving farmers’ welfare,” Suryatmi said, while expressing her appreciation for Harita Nickel’s continued support for local food security initiatives.
The support is provided through the Obi Food Security Centre (SENTANI). The initiative has grown from two initial farmers’ groups to three: Milenial, Akemoriri and Batu Putih. Together, they have 42 members cultivating 30 hectares of farmland.

This harvest season, the three groups are expected to harvest around 25 hectares. In addition to the Millennial group, Akemoriri and Batu Putih are also scheduled to harvest, with crop-cutting results from some plots exceeding 8 tonnes per hectare.
Harita Nickel Community Development Manager Broto Suwarso said the harvest amid abnormal weather conditions highlighted the importance of climate-resilient agriculture supported by local knowledge.
“Obi’s farmers have valuable local knowledge for reading weather patterns, understanding land conditions and managing water availability. This knowledge needs to be further developed to make agriculture more climate-resilient and strengthen food security,” Broto said.
Adaptation measures include selecting varieties suited to local conditions, managing irrigation on a rotational basis and using dryland areas for secondary crops. Interest in farming is also growing, with around 15 residents planning to establish a new farmers’ group.
Darwan Aduhasan, Chairman of the Pelangi Community (Pioneers of Obi Food Sovereignty) and a pioneer of agriculture in Buton Village, said this growing interest needs to be supported by an ecosystem that gives farmers greater confidence to invest in and expand their agricultural activities.
“For us, agriculture is the future, not the past. We want to build modern farmers and an agricultural sector that brings greater prosperity to the community,” he said.
The Millennial Farmers’ Group’s first harvest offers an early indication of Obi’s agricultural potential. With cross-sector collaboration, local knowledge and sustained support, agriculture can become an increasingly important contributor to food security and new economic opportunities for communities in Obi.

Obi’s Millenial Farmers Exceed National Rice Yield Target

Among Harita Nickel's diverse employees, dance has become a language that brings people together. Through traditional movement, they learn about different cultures, share stories, and build a stronger sense of togetherness.
In a workplace that brings together people from across Indonesia, Sanggar (dance studio) Masigaro offers a space to explore the nation's rich cultural heritage through dance. It is not devoted to the culture of a single region. Instead, it embraces the many art forms that its members bring and share.
The dance studio was founded on 29 November 2025. The name Masigaro comes from a local language of Ternate, North Maluku, and means "to invite." That meaning reflects the group's spirit of inviting employees to learn about, study, and preserve Indonesian culture together.
The idea came from Saddam Hi Kasim, an Industrial Relations staff member at PT Karunia Permai Sentosa (KPS), a Harita Nickel business unit. Saddam noticed that, amid busy work schedules, some employees had an interest in and experience with dance but no place to pursue it.
"I know that our colleagues here enjoy more than just basketball and singing. Some love to dance as well. So there is nothing wrong with the company providing a space for them to pursue their passion for traditional dance," said Saddam.
The invitation received a positive response. Today, about 20 employees have joined Sanggar Masigaro. They come not only from North Maluku but also from other parts of Indonesia, each with a different background and cultural experience.

For Syahril Abd Rauf, one of the members, this diversity is a big part of the appeal. The dance studio has connected Syahril with colleagues who share the same interest. It has also opened the door to learning about art forms from other regions.
"I am happy to meet people who share my interest in dance. Here, I can also learn about and get to know dances from other regions that I did not know before," said Syahril.
Learning takes place in two classes, one for professionals and one for beginners. Those with experience share their knowledge, while beginners have room to learn and grow together.
That togetherness was then brought to the stage. At Herophoria #6, held to celebrate the 81st anniversary of Indonesian Independence, Sanggar Masigaro performed the Katreji dance. This art form from Maluku blends local culture with European influences.
In its latest performance, the group presented the Dendang Ba Lala dance, also known as Ba Dendang Cobo Lala. This art form belongs to the Malay cultural family and has been part of life for centuries in the territory of the Bacan Sultanate. It is a traditional cultural expression typical of South Halmahera and has been protected as communal intellectual property.
The company supports the group's growth, including by providing a rehearsal space and opportunities to perform at various company events.

Looking ahead, Saddam hopes Sanggar Masigaro can grow into a broader platform. He envisions employees from Harita's various business units sharing their knowledge and love for regional arts.
More than a way to pursue a hobby, the dance studio has become a place where people meet. For its members, dance can be a way to learn about other cultures, strengthen fellowship, and ease the longing for their hometowns.
At Sanggar Masigaro, differences in regional origin do not remain mere differences. Through dance, employees get to know one another, share their cultures, and nurture their love for the heritage of the archipelago. That spirit also strengthens fellowship and brings to life the value of Bhinneka Tunggal Ika (Unity in Diversity) and the spirit of One Harita, Looking Out for Each Other.<script src="https://cdn.n1ed.com/widgets.js?apiKey=FLMNFLMN" data-ts="1790045612802"></script>

Sanggar Masigaro: When Dance Becomes a Language That Unites

Water flows 24 hours a day as part of daily life for residents of Kawasi Village's New Settlement. From basic needs like bathing and washing to cooking, a clean water supply is available whenever it is needed.
"Water is always there for bathing, washing, and cooking. Even if I want to bathe five times a day, there is still enough," said Yunince, a resident of Kawasi Village's New Settlement.
For Tina Nomor, a small business owner in the settlement, stable access to water and electricity supports her daily activities and her business. Even though both are available around the clock, she understands the importance of using them wisely.
"Reliable water and electricity help our business a lot. Everything is provided, so it eases our daily needs. Even so, we still use only what we need," she said.
Behind this supply is a series of steps that ensure water from the Akelamo River is treated before it reaches residents' homes. Raw water is pumped through a water intake facility to the Water Purification Plant (WPP), which is operated by Harita Nickel.
<figure class="image"><img src="https://api.tbpnickel.com/storage/images/Media/Liputan/Kabar%20Obi/sorotan/image2_7.jpg" alt="UGM Community Service (KKN) students and a media group observed the water treatment process firsthand at the Water Purification Plant (WPP), which supplies clean water to residents of the Kawasi Village New Settlement." width="720" height="480">

At the WPP, water first goes through a clarification process in a Rectangular Clarifier. Coagulants and flocculants help settle particles out of the water. The clarified water is then held in a Reservoir Pond before undergoing disinfection with Sodium Hypochlorite (NaOCl) to control microorganisms.
Amiruddin, Head of Technical Support at PT Obi Sinar Timur, explained that each stage is part of the water treatment process before distribution to the community and the industrial area.
"Raw water first goes through treatment and clarification before it is distributed. Its quality is also monitored regularly," he explained.
Quality is monitored from the water source, through the treatment process, to the point of distribution. Testing is carried out by an internal team and verified periodically through an accredited external laboratory.
To meet the needs of residents in Kawasi Village's New Settlement, the WPP supplies about 42,000 cubic meters of clean water each month. The same facility also supports the industrial area's water needs, with average use of about 1.75 million cubic meters per month.
Water management does not stop at treatment and distribution. Resource efficiency is also part of the system, through the reuse of process water in operational activities.

Clean water service is also provided to residents who still live in Kawasi Village's Old Settlement. Water quality in that distribution network is monitored regularly through internal testing and verified periodically by an accredited external laboratory.
For residents, the benefit feels simple: water is available when needed. Behind that flow, however, is a treatment and monitoring process that runs every day. From the Akelamo River, water passes through a series of stages before it finally flows into the homes of Kawasi residents.
This effort is part of Harita Nickel's support for expanding community access to adequate drinking water and sanitation. It also encourages the efficient and sustainable management of water resources on Obi Island.
