Thecuy.com – PT Stargate Mineral Asia (SMA) adalah sebuah perusahaan pemurnian (smelter) nikel yang berlokasi di Desa Molore, Kecamatan Langgikima, Kabupaten Konawe Utara, Sulawesi Tenggara. Perusahaan ini merupakan bagian dari ekspansi PT United Tractors Tbk ke sektor pertambangan dan pengolahan mineral, setelah UNTR melalui anak perusahaannya, PT Danusa Tambang Nusantara, mengakuisisi mayoritas saham PT Stargate Mineral Asia bersama perusahaan afiliasinya, PT Stargate Pasific Resources (SPR), pada akhir tahun 2022. Bijih nikel yang diolah oleh SMA disuplai langsung dari tambang milik SPR di Konawe Utara, sehingga rantai pasok bahan baku antara tambang dan smelter terintegrasi dalam satu kawasan industri yang dikenal sebagai Stargate Industrial Park.
Smelter PT Stargate Mineral Asia menggunakan teknologi Rotary Kiln Electric Furnace (RKEF) untuk memproduksi nickel pig iron (NPI), bahan baku penting bagi industri baja tahan karat dan baterai kendaraan listrik, dengan target produksi mencapai puluhan ribu ton per tahun. Sebagai bagian dari Grup Astra, PT Stargate Mineral Asia terus memperkuat kapasitas produksinya seiring dengan komitmen investasi lanjutan dari PT United Tractors Tbk untuk pengembangan hilirisasi mineral nikel di Indonesia. Pertumbuhan operasional ini membuka peluang karier di berbagai bidang teknik dan produksi bagi tenaga kerja lokal maupun profesional berpengalaman yang tertarik berkarier di industri smelter nikel Sulawesi Tenggara.
