Harita Nickel through one of its subsidiaries, PT Halmahera Jaya Feronikel (HJF), recently held a drill or training to comply with the quality standards of the Waste Water Treatment Plant (WWTP). Drill conducted by the Department of Health, Safety & Environment (HSE) aims to improve the preparedness of the team on duty in the field.
Dressed in gray uniforms complete with masks and vests along with supporting equipment, the team conducted a drill in the employee mes WWTP area. The team simulated the steps that need to be taken when they found the content in the waste exceeded the established quality standards.
 
In this drill, the scenario involved the sampling team discovered the ammonia levels in the wastewater outlet exceeded the quality standards. Following this, swift action was taken to address the situation. The sample was immediately sent to the laboratory for validation. If the results confirmed the breach of the quality standards, the operational team would be notified via internal radio communication for further action.
 
Environment Supervisor HJF Bobby Loys Lengga explained, “Validation was needed to ensure the next actions taken were based on reliable data. Following this, control procedures for handling the situation were directly implemented.”
These procedures included shutting the main valve to prevent further wastewater flow. The HSE team then prepared to use nutribac, a substance designed to accelerate the growth of bacteria or microbes that aid in wastewater treatment, ensuring the WWTP operates efficiently and meets the required water quality standards as per applicable regulations. Additionally, the emergency blower was activated to support the aeration process in the WWTP.
 
“By shutting off the flow and injecting nutribac, we ensure that the treatment process can resume optimally, accelerate the reduction of ammonia levels, and restore the water quality to meet the standard,” said Bobby.
 
Once ammonia levels return to normal and align with the standards, the team will continue to monitor and conduct further sampling, both in the field and at the laboratory, for validation.
Bobby further explained that drill like this are crucial for maintaining the team’s readiness to handle unforeseen situations. “This kind of training is essential to enhance the team’s preparedness. Moreover, we want to ensure that every member knows exactly what actions to take if an emergency situation arises,” he stated.
Through this drill, HJF demonstrates its strong commitment to effective and responsive environmental management. This drill not only serves to prepare tactical personnel for field emergencies but also reinforces the reminder that maintaining environmental quality is an integral part of the company’s operations and responsibilities.

Raising Preparedness, HJF Held Quality Standard Compliance Drill

PT Trimegah Bangun Persada Tbk (NCKL) or Harita Nickel, a sustainable integrated nickel mining and processing technology company operating in Obi Island, South Halmahera, North Maluku, has inaugurated the new Ternate Representative Office (KPT) building located in Kalumata Village, South Ternate District, Ternate City.
The inauguration of the new KPT building was led by the President Commissioner Donald J. Hermanus, on Monday, November 4, 2024. Also present at this event were the Head of South Ternate Sub-District, Danramil Ternate, South Ternate Police Chief, and Head of Kalumata Village.

New Building, New Hope: Inauguration of Ternate Representative Office

The futsal court at the employee&nbsp; living quarter&nbsp;of PT Halmahera Jaya Feronikel (HJF) was filled with excitement. The cheers of the audience blended seamlessly with the resonant sound of musical instruments. That evening, a friendly futsal match between business units within the partnership of Harita Nickel and Lygend Resources was taking place.
What set the event apart was that the match, involving employees at the supervisor level and above, was presented in the style of a professional game. This included player arrivals by bus, chants and coordinated attire among supporters, and even press conferences with team managers. It felt as though one was watching the national team in action.
A moving moment occurred when the players, along with the spectators filling the stands, sang the Indonesian national anthem, “Indonesia Raya.” Rico W. Albert, Head of Technical Support at PT Halmahera Persada Lygend (HPL), expressed how touched he was to be in the middle of the arena, which featured a match between the Warrior team&mdash;a combination of HJF, PT Karunia Permai Sentosa (KPS), and PT Obi Sinar Timur (OST)&mdash;and the Apache team, comprised of HPL, PT Dharma Cipta Mulia (DCM), and PT Obi Nickel Cobalt (ONC).<img alt="C1 fun futsal hjf vs hpal 98 11zon" src="https://apiharitanikel.dipstrategy.co.id/storage/images/old/images/C1_Fun Futsal_HJF vs HPAL_98_11zon.jpg"> 
Rico noted that while employees and management usually meet in formal work settings, that night they could mingle freely and enjoy a joyful atmosphere, whether as spectators or players. Rico himself, as a representative of the management on-site, took to the field to strengthen the Warrior team’s offensive lineup. Despite this, everyone gave their best effort on the field. There was no hesitation, for example, when needing to steal the ball from a higher-ranking opponent.

“This event is very positive because it embodies the core values of Harita. Especially in building strong teamwork,” he said, emphasizing that such events should be held regularly and include not only futsal but other sports as well.

Rico also specifically praised HJF for hosting the first match and challenged HPL, which will host the second match, to make it even more festive.

Committee Coordinator Christoforus Nanda Rahardian stated that the friendly futsal match between HPL and HJF involved all departments. Regarding the match’s professional game-like concept, he noted that it was to create a more lively atmosphere.

“The spirit is not just about playing futsal but more about how everyone can participate in the activity,” said Christo, who in his daily role serves as an Employee Relations Specialist at KPS.

The match between Warrior and Apache ended with a score of 1-3 in favor of the visiting team. Apache will host Warrior for the second match, which will be held at the HPL futsal court.

Fostering Solid Teamwork Through a Friendly Futsal Competition

The lush sengon and sea pine trees provided a refreshing shade for Mokhamad Rifai and Bagas Nicolaus Saputra. In the scorching midday heat, the two were engaged in monitoring activities at the Komodo reclamation area owned by Harita Nickel. This 11.82-hectare area, previously a mining site, has now returned to a vibrant green, inhabited by a variety of wildlife.
Mokhamad Rifai, the Mine Reclamation Superintendent at Harita Nickel, stated that the reclamation activities in the mining area are part of the company's obligations, as outlined in the Mineral and Coal Mining Law (UU Minerba) No. 3 of 2020. These activities are conducted in areas that have been declared mine-out.
He explained that a mining site can be declared mine-out when the extraction process has reached the bedrock layer. This means that the mining material in the ground has been exhausted or has reached its limit.
As of now, Harita Nickel has successfully reclaimed 201 hectares of post-mining land, according to Mokhamad Rifai, the Mine Reclamation Superintendent. This achievement encompasses a strategic collaboration between PT Trimegah Bangun Persada Tbk (TBP) and PT Gane Permai Sentosa (GPS).
“Reclamation goes beyond fulfilling corporate obligations; it’s crucial for restoring the ecological integrity and functionality of former mining sites,” Rifai stated, emphasizing the dual responsibility of environmental stewardship and compliance with regulations.
 <img alt="Reklamasi 24 11zon" src="https://apiharitanikel.dipstrategy.co.id/storage/images/old/news_assets/Reklamasi_24_11zon.jpg">
To achieve this, Harita Nickel employs a range of plants specified in the Environmental Impact Assessment (Analisis Mengenai Dampak Lingkungan or AMDAL), focusing on species capable of thriving in the harsh conditions typical of post-mining landscapes. Key plants include sea pine, bintangor, gofasa, and other resilient species known as pioneer plants.
 
These plants not only survive but also improve soil fertility. Their roots release substances that attract beneficial bacteria and help prevent soil erosion, greatly enhancing soil structure and nutrient content.
 
In addition to these pioneer species, the reclamation area features several indigenous trees from Obi Island, aimed at restoring the original ecosystem and attracting the island’s endemic wildlife. “We’re focused on bringing this reclaimed area back to its natural state. This year, we’re targeting 30 hectares for reclamation,” said Bagas Nicolaus Saputra, the Reclamation Operation Foreman at Harita Nickel.
 
However, reclaiming land on Obi Island isn’t without its challenges. Unpredictable weather conditions often complicate the planting schedule.
 
“Sometimes it rains too much when the land isn’t ready, and then when it is ready, there’s no rain,” Bagas said, pointing out how these weather changes can impact planting success and plant growth.
 
Rifai and Bagas stressed that a flexible approach is needed to adapt to changing weather patterns. Despite the challenges, Harita Nickel is committed to making its reclamation program successful and promoting sustainable ecosystem restoration.
 
To ensure accountability and effectiveness, Harita Nickel regularly monitors and evaluates its reclamation efforts with help from external experts. This includes measuring plant growth, checking soil quality, and tracking the wildlife in reclaimed and mining areas. The insights gained from this monitoring are used to improve future reclamation and revegetation efforts.

Facing Weather Challenges, Harita Nickel's Reclamation Successfully Reclaims Former Mining Areas

Harita Nickel hosted a graduation ceremony for the Youth Vocational Program (Pelita) on Monday, September 2, 2024, at the Obi Island site in South Halmahera, North Maluku. The 28 graduates had successfully completed a three-month training program focused on operating Overhead Crane heavy equipment.
Through this vocational program, Harita Nickel provides opportunities for local employees in its operational area to improve their skills while also developing their career paths.
Latif Supriadi, Head of External Relations at Harita Nickel, stated that Pelita is part of the company's Community Development and Empowerment (PPM) program in education. He continued by explaining that this vocational program aims to support the sustainability of the company's business by fulfilling the need for a skilled workforce.
"Through Pelita, we are contributing to the government's vision of creating vocational education that meets the needs of today’s industry," he remarked.
This Pelita program is the second batch, following the successful graduation of 14 participants who were previously trained to operate Wheel Loaders, consisting of crew members and daily laborers (THL). This program not only teaches heavy equipment operating skills but also equips participants with mental and physical training, as well as important materials on workplace safety.
"The Pelita vocational education program teaches not just heavy equipment operation but also other essential skills for the company's operations. This is a key step in achieving operational excellence at Harita Nickel," Latif added.
<img alt="C2 dokumentasi kegiatan kelulusan pelita batchii csr 2024 dsc083111 11zon" src="https://apiharitanikel.dipstrategy.co.id/storage/images/old/images/C2_Dokumentasi_Kegiatan_Kelulusan_PELITA_BatchII_CSR_2024_DSC083111_11zon.jpg">
The Head of the Industrial Relations Development Division at the South Halmahera Manpower Office, Ladama La Sabadu, who also attended the event, expressed appreciation to Harita Nickel for continuing its commitment to improving local human resources. Ladama also advised the participants to make the most of the opportunities provided by the company.
“Let us grow and develop the spirit to learn and improve skills and show that South Halmahera's human resources can compete with other regions,” he said.
Meanwhile, participant Fajri Kadili expressed his happiness at completing the Pelita activities and graduating. This resident of Buton Village in Obi Subdistrict, who was previously a crew member, will now be appointed as an operator.
"Thank goodness we have such a great job here with excellent wages and facilities, along with opportunities to improve our skills," said Fajri.
 
Unlike the first batch graduation ceremony, this event included the participants' parents. Jafar Kadili, Fajri Kadili's father, expressed pride that his son works at Harita Nickel and has the chance to improve his skills.
"I am very proud that the company has given my child, who had no skills before, the chance to become a heavy equipment operator. I encouraged my child to work hard and be disciplined to make us proud," he said.
 
The second batch of the Pelita vocational program included 28 local employees from PT Halmahera Jaya Feronikel (HJF), a business unit of Harita Nickel, and lasted three months. Participants received classroom lessons and field practice under the guidance of experienced mentors. The graduation ceremony marked the end of the training, and those who were crew members will now become Overhead Crane operators

Harita Nickel Continues to Invest in South Halmahera Youth with Heavy Equipment Operation Training

Harita Nickel has introduced a new initiative&mdash;Produk Unggulan Olahan Rempah Maluku Utara, known as Propala, as part of Harita Nickel’s broader Community Development and Empowerment Program (Pengembangan dan Pemberdayaan Masyarakat or PPM). This program specifically targets local women, particularly mothers, now residing in the new settlement of Kawasi Village.
Harita Nickel has launched Produk Unggulan Olahan Rempah Maluku Utara, known as Propala, a new initiative under its Community Development and Empowerment Program. This program focuses on local women, especially mothers, living in the new settlement of Kawasi Village.
 
Ifan Farianda, Harita Nickel's Community Development Manager, explained that Propala was designed as a platform to empower local women by diversifying the use of nutmeg, a crop deeply rooted in the history of North Maluku. Despite nutmeg being the region’s one the most prized commodity, its full potential has long been overlooked. The nutmeg seed has always been harvested, but the flesh, which makes up the majority of the fruit, has been left untapped.
 
“The flesh of the nutmeg is both sweet and slightly tangy, and can be transformed into an array of products, including nutmeg syrup, jam, and the chewy confection, similar to Turkish Delight, known as dodol,” Ifan remarked. 
 
To unlock this potential, Harita Nickel has enlisted the help of small business entrepreneurs from Ternate, who have been conducting training workshops for the women in Kawasi. 
 <img alt="C2 dokumentasi kegiatan propala csr 2024 a74085931 11zon" src="https://apiharitanikel.dipstrategy.co.id/storage/images/old/images/C2_Dokumentasi_Kegiatan_Propala_CSR_2024_A74085931_11zon.jpg">
In a recent workshop, 30 women learned how to process nutmeg into drinks and snacks, as well as how to package these products attractively. The sessions not only provided technical skills but also focused on building entrepreneurial confidence and instilling the basics of running a business.
 
“The mothers in Propala are a new group, joining other women-led businesses we've helped before. This is part of our ongoing effort to support the community's economic stability, especially as they adjust to their new homes,” Ifan added.
 
In a further boost to their business prospects, Harita Nickel has helped secure Pangan Industri Rumah Tangga or PIRT certification for five Propala products: nutmeg syrup, fruit concentrate, air guraka (a traditional herbal drink), jam, and dodol. These certifications open doors for wider market access, allowing the women to sell to employees heading home on leave or visitors to the site.
 
Fauzia, a member of the Propala group, expressed her excitement at participating in the program. “I used to think nutmeg was only valuable for its seeds. Now, we’re making syrups, dodol, candies, and even air guraka. Our region is rich in spices, but before the company came, it was hard to find buyers or even get our hands on the ingredients. But now, with the economy improving, selling these processed products is much easier,” she shared, hopeful for the additional income Propala could bring.
 
The new settlement of Kawasi village, supported by the government and facilitated by Harita Nickel, provides residents with better housing. Since moving in, the community has started to grow economically, with people opening grocery stores and vegetable stalls to serve others.
 
In Propala, Harita Nickel has not only invested in the local economy but in the future of Kawasi’s women, offering them the tools and training to build a sustainable livelihood in the heart of North Maluku’s spice-rich landscape.

Empowering Kawasi Mothers: Harita Nickel Launches Propala in New Settlement

The sky above Pasturi, a small island amidst the waters of Kawasi, is clear. After two days of choppy waves, the sea this morning is calm. The dive team can finally carry out their activities at the blue hole&mdash;a patch of deep blue water surrounded by white sand.
On this morning (August 16, 2024), divers from Harita Nickel’s various business units are about to raise the Red and White flag beneath the sea. This initiative, part of Indonesia’s 79th Independence Day celebrations, symbolizes the company's commitment to preserving the waters around Obi Island.
Jesaya Alfredo, Marine Environment Supervisor at PT Halmahera Persada Lygend, explains that Pasturi's sandy waters are one of three points included in Harita Nickel’s coral reef restoration program. Since its launch in 2021, a total of 1,696 artificial coral reefs have been placed. These cube-shaped, hollow coral structures, made from nickel slag byproducts, have since become home to marine life as natural corals grow on them.
“Why is the water in Kadera calmer than in Pasturi?” Jesaya asks rhetorically. “That’s because Kadera is shielded by several islands, while Pasturi's waters are exposed to the open sea.”
An alumnus of the Bandung Institute of Technology (ITB), where he studied oceanography, Jesaya explains that waves are influenced by both weather and season. He elaborates that Indonesia’s waters experience two primary seasons: west and east. August falls within the eastern season, where the monsoon winds blow from Australia to Asia from April to October.
He goes on to describe the unique nature of Obi’s waters, which, like much of Eastern Indonesia, boast deep seas and breathtaking underwater views. More than that, Obi’s waters are particularly productive due to the meeting of two major ocean currents&mdash;the Indian and Pacific Oceans.
“This convergence is known as Arlindo,” Jesaya says, “and one of its entry points is through the waters of eastern Indonesia, including Obi. Here, you’ll find plenty of fish with high economic value, though they’re far offshore.”
<img alt="Whatsapp image 2024 10 03 at 2.02.43 pm" src="https://apiharitanikel.dipstrategy.co.id/storage/images/old/images/WhatsApp Image 2024-10-03 at 2.02.43 PM.png"> 
Back to Pasturi, the divers from Harita Nickel’s business units have returned here several times over the past three days, determined to complete their dives. Although they could have been content with diving in Kadera&mdash;another small island near the village of Laiwui&mdash;their sights were set on Pasturi.
“Why are they so eager to dive in Pasturi?” Jesaya smiles. “Besides the stunning underwater views, the blue hole here has much clearer water.”
Remarkably, despite being near the operations of a mining and nickel processing company, the waters of Kawasi remain well-preserved. Thanks in large part to the diligent efforts of Harita Nickel’s Environmental Marine team, of which Jesaya is a key member.
The core mission of the Marine Environmental division is to monitor the waters surrounding the company’s operations. This includes regular checks on marine ecology and water quality. On the ecology front, their routine involves monitoring the growth of coral reefs and identifying the various species of fish in the area. They also keep tabs on meteorological and oceanographic conditions. As for water quality, the team conducts tests on a weekly, monthly, and quarterly basis.
To support these efforts, the team is equipped with advanced tools. Among them is a seawater sampling device outfitted with a CTD meter (conductivity, temperature, and depth) to measure ocean water profiles, and a remotely operated vehicle (ROV) used to inspect underwater structures like piers and pipelines, as well as aquatic environments inaccessible to divers.
“Management has been incredibly supportive, providing us with the necessary equipment. On top of that, they offer us opportunities to enhance our skills through training and certifications,” Jesaya says.
He reflects on the journey that began in 2019, noting how his role has allowed him to delve deeper into the knowledge he gained in school. He feels fortunate to be pursuing a career that aligns with his passion. For him, the sea is a vital source of life, not just for the creatures within it, but also for humans on land.
“The challenge is that Harita Nickel’s operations are so close to the ocean, which means we have to work extra hard to preserve it. But thankfully, we’ve been able to show results,” he says, expressing pride in being part of a company so committed to environmental preservation.

Jesaya Alfredo: The Guardian of Obi’s Seas

Harita Nickel’s mining and nickel ore processing operations are deeply committed to environmental safety, particularly in ensuring that the water discharged from mining areas poses no threat to the surrounding ecosystems. Given that the company’s operational areas border vital aquatic zones, which are home to diverse marine life and crucial to the livelihoods of local fishermen, this commitment takes on added urgency.
To protect the quality of water leaving the mine, the company has created 52 settling ponds across two mining licenses. Thirty-five of these ponds are managed by PT Trimegah Bangun Persada, and the other seventeen by PT Gane Permai Sentosa. The largest pond, Tuguraci 2, has a capacity of 924,000 cubic meters and covers an area of 43 hectares.
Muhamad Riftadi Hidayat, a Senior Mine Hydrology Engineer at PT Trimegah Bangun Persada Tbk, highlights the importance of settling ponds in capturing sediment from soil, rock, and other materials eroded by mining. If not managed, these particles could pollute the environment. “These ponds are essential for keeping the water clean and safe before it's released back into the waterways,” he says.
The settling ponds are carefully designed to allow water to effectively filter out sediment before it is returned to its natural flow. This process ensures that the discharged water is clear and meets strict government quality standards.
At Harita Nickel, managing the settling ponds involves monitoring water quality parameters like pH and Total Suspended Solids (TSS). Dedicated teams from various business units perform daily checks to ensure they meet strict environmental standards.
<figure><img alt="C1 settling pond bunaken 2 50 11zon" src="https://apiharitanikel.dipstrategy.co.id/storage/images/old/images/C1_Settling Pond Bunaken 2_50_11zon.jpg" title="C1 settling pond bunaken 2 50 11zon"><figcaption>Harita Nickel Employees Conduct Water Monitoring at the Settling Pond Facility</figcaption></figure>

Indra Maizar, Environmental Superintendent at PT Halmahera Persada Lygend, explains the importance of regular maintenance. The company regularly dredges the ponds when sediment builds up to 70 percent of their capacity. “When sediment reaches 80 percent, we use heavy machinery to deepen the pond,” Indra says.
Dredging prevents sediment buildup from reducing capacity and keeps the water clear before it flows into places like the Todoku River. “Pond Tuguraci 2 can handle water flow rates of 10,000 to 50,000 cubic meters per hour, even during heavy rain,” he adds. The pond also has a retention time of 10 to 15 hours, which helps ensure that upstream water is clear before being released.
“These ponds clearly show the company’s commitment to protecting the environment around the mine,” Indra says. “They also reflect one of Harita Nickel’s core values: teamwork. All business units will keep working toward sustainability and environmental conservation in our operational areas.”

Collaborating for a Greener Future: Harita Nickel's Water Management Initiative

In early June 2024, the JH Hutasoit Auditorium at the Faculty of Animal Science, IPB University in Bogor was filled with hundreds of excited students attending a lecture on environmentally-friendly mining. This event was part of the "Harita Nickel Goes To Campus" (HGTC) program initiated by Harita Nickel, marking the fourth campus visit in this series.
Ir. Tonny Gultom, the Director of Health, Safety, and Environment at Harita Nickel, was the speaker for the lecture, titled “Mining the Future: Environmentally Friendly and Sustainable Nickel for Indonesia.” The talk was moderated by Dr. Ir. Iskandar, a lecturer in Land Resource Management at IPB University.
Tonny was joined by other Harita Nickel leaders, including Latif Supriadi (Head of External Relations), Dr. Retno Dewi Handayani (Green Mining Manager), Windy Prayogo (Environmental Marine Manager), and Dr. Irdika Mansur (Head of the Research Laboratory at IPB University).
The audience consisted of 229 students from various faculties, including Agriculture, Forestry, Fisheries, and Economics.
During the event, Tonny stated that Harita Nickel places the principles of Environment, Social, and Governance (ESG) into all its operational activities. He provided examples of various reclamation programs aimed at restoring ecological functions to areas that have been mined.
Dr. Ir. Irdika Mansur, M.For.Sc., from IPB University, emphasized the important role of IPB alumni in the mining industry. He noted that alumni from various disciplines, including community empowerment, forestry, and post-mining land utilization, are greatly needed in this sector.
Students who attended the lecture reported gaining new insights. Niko Bakri, a student from the Forestry and Environment Department of Silviculture, stated, “I gained many new insights that the mining world is not only for mining engineering students but is also open to students from the Forestry Faculty.”
M. Faransani from the Agriculture Faculty, who studies Land Resource Management, shared a similar view. “I want to learn about environmental management in mining, and this event has taught me about reclamation and sustainability,” he said.
To keep students engaged, Harita Nickel organized competitions with the Student Executive Board (BEM) of the Agriculture Faculty, including an infographic contest, a creative video production contest, and an essay competition. These competitions aimed to promote discussions about sustainable nickel mining in Indonesia, with 57 students participating.
In addition to reclamation, Tonny mentioned that Harita Nickel also focuses on revegetation and using former mining sites for factories.
Harita Nickel is dedicated to preserving the quality of seawater around its operations by monitoring coral reefs and adding artificial reefs in Kawasi waters. These reefs provide homes for fish and marine life, helping to maintain biodiversity.
Latif Supriadi highlighted several economic empowerment programs by Harita Nickel on Obi Island, including the Gemar Papeda initiative and the Obi Food Resilience Center (Sentani). These programs have created 691 jobs and supported 65 local suppliers and 26 farmer groups. “There are about 30,000 employees on Obi Island, with monthly transactions reaching IDR 13.2 billion,” Latif said.

Shaping Future Leaders: IPB University Students Discover Sustainable Mining with Harita Nickel

Harita Nickel's successful nickel mining and downstream operations on Obi Island have received praise from academics at Universitas Padjajaran (UNPAD) in Bandung. Professor Mega Fatimah Rosana, a seasoned geology expert at UNPAD, has called the company's practices a model for others to emulate.
During a recent visit to the Obi site, Professor Mega and her colleagues, Dr. Boy Yoseph Cahya Sunan Sakti Syah Alam and Dr. Mochamad Candra Wirawan Arief, observed Harita Nickel's operations from extraction to processing.
Her praise is well-deserved. She believes Harita Nickel strictly follows regulations and shows a commitment to responsible mining practices, including nickel processing and water management, ensuring that discharged water meets environmental standards before reaching the sea.
“I believe Harita Nickel complies with regulations and meets all its environmental obligations. In fact, I would say what they have done exceeds their obligations,” she remarks.
Professor Mega praises Harita Nickel for its effective conservation of mineral resources. The company has turned low-grade limonite, which was once considered waste, into a valuable product using High-Pressure Acid Leaching (HPAL) methods.
“Even the waste from the nickel processing plant, in the form of slag, is repurposed into building materials. I’ve seen the quality of these structures firsthand; they are impressively sturdy,” she adds.
Beyond environmental considerations, she appreciates the company’s commitment to community welfare. Harita Nickel not only supports local government initiatives for regional development and improving residents' living standards but also provides essential facilities, including schools, places of worship, and shopping centers.
“The facilities in this new settlement are more than adequate. I observed that schools are running smoothly, and the local economy is thriving as residents get involved in trade,” she says, highlighting that Harita Nickel's approach could serve as a model for other companies.
The visit by the three UNPAD academics aimed to assess the company’s operations and reinforce its partnership with educational institutions, as well as engage with other stakeholders. During their visit, they also attended the Enviro Talk event, held in celebration of World Environment Day, where one of the participants, Mochamad Candra Wirawan Arief, Ph.D., served as a speaker. They also connected with UNPAD alumni working across various business units at Harita Nickel.
“My long and exhausting journey from Bandung to here was well worth it after witnessing the extraordinary activities of this company. Engaging with enthusiastic employees and reconnecting with alumni here has been truly rewarding,” she concludes.
