Batam, 10 July 2025 – PT Solder Tin Andalan Indonesia (STANIA), a subsidiary of Arsari Tambang, officially launched its first solder manufacturing plant located at Tunas Prima Industrial Estate (TPIE) in Batam today. This milestone supports Indonesia’s national mineral downstreaming agenda initiated by President Prabowo, while demonstrating Arsari Tambang’s commitment to becoming a pioneer in environmentally friendly tin-based products in Southeast Asia.
Built on a land area of 6,500 m² within the 100-hectare TPIE, a Greenmark-certified international-standard industrial estate developed with sustainability principles in every aspect, the plant’s construction was completed in less than one year since its groundbreaking in May 2024. The factory is ready to produce up to 2,000 tons of solder bars per year, with future expansion plans to include solder wire, powder, and paste production reaching a total capacity of up to 16,000 tons annually.
“This grand launching is our concrete commitment to supporting Indonesia’s downstreaming agenda while responding to global challenges in energy transition and sustainability. It marks the beginning of Arsari Tambang’s long journey towards a responsible mining industry,” said Hashim S. Djojohadikusumo, President Commissioner of Arsari Tambang.
TPIE, developed and managed by Tunas Industrial, welcomed the operational commencement of PT STANIA’s facility as further evidence of its positioning as a premier industrial hub in Batam and Indonesia. With its strategic location, integrated infrastructure, and a sustainability-focused environment, TPIE has become an investment magnet for local and multinational companies looking to expand in Southeast Asia.
Aryo P. S. Djojohadikusumo, President Director of Arsari Tambang, added, “PT STANIA is part of our vision to build a tin-based industrial ecosystem, positioning Indonesia as a major global player in the tin product supply chain. Through green technology utilization and strategic collaboration, we aim to prove that the mining industry can simultaneously champion sustainability.”
PT STANIA’s plant operates with electricity sourced entirely from PLN’s Renewable Energy Certificate (REC)-certified power, making it an emission-free facility. Its building design optimizes energy efficiency with extensive transparent roofing to maximize natural lighting and reduce electricity usage.
The inauguration was attended by Deputy Minister of Investment and Downstreaming, Todotua Pasaribu, who stated, “This plant is tangible evidence of private sector collaboration with the government’s grand vision. Downstreaming creates added value, generates employment, and enhances Indonesia’s industrial competitiveness.” Governor of Riau Islands, Ansar Ahmad, also welcomed PT STANIA’s investment as a catalyst for regional industrial transformation, technological advancement, and economic growth in Batam.
With an initial investment of IDR 400 billion, PT STANIA targets becoming one of the world’s leading solder producers, supporting Indonesia’s industrial growth while strengthening its role as Southeast Asia’s leading tin downstream hub. Its products will support electronic manufacturers in Batam and global export markets, reinforcing Indonesia’s strategic position in the international solder supply chain.
