Powering Nvidia and Intel: Arsari Tambang to Build High-Tech Tin Research Center for Semiconductor Supply Chain

JAKARTA, Investortrust.id — Arsari Tambang, the mining arm of the powerful Arsari Group, is shifting its focus from the pit to the lab. CEO Aryo Djojohadikusumo announced on Tuesday that the company will build a dedicated Tin Research Center in the Bangka Belitung Islands to capture a slice of the global semiconductor boom.

This is a sophisticated evolution of Indonesia's downstreaming mandate. While most miners stop at smelting, Arsari is targeting the high-precision "solder paste" required by industry titans like Nvidia and Intel. By moving into R&D and proprietary chemical formulations, Indonesia is no longer just selling "dirt"—it is positioning itself as a critical, high-tech link in the global AI and chip-making supply chain.

The "Solder Paste" Breakthrough

Following the MetConnex 2026 conference in Jakarta, Aryo Djojohadikusumo made it clear that "downstreaming" is a misnomer if it doesn't include advanced manufacturing. He identified solder paste as the key high-value product that can bridge Indonesian minerals with Silicon Valley needs.

"We found that one of the largest added values in the tin industry is solder paste. This solder paste is used for semiconductors utilized by Nvidia, Intel, and others," Aryo explained. To meet the exacting standards of these tech giants, Arsari is betting big on local intellectual property. "Because this has never been built in Indonesia before, Arsari Tambang is initiating the Tin Research Center in Bangka Belitung."

Beyond Mining: A $25 Million Bet

The research center is the brain for a broader industrial body. Arsari’s subsidiary, PT Solder Tin Andalan Indonesia (Stania), has already committed a total investment of Rp 400 billion ($25.1 million) for a production facility in Batam.

Hashim Djojohadikusumo, Chairman of Arsari Tambang and brother to President Prabowo Subianto, previously noted that the Batam facility targets an initial output of 2,000 tons per year with an expected turnover of $75.4 million (Rp 1.2 trillion).

"Our goal is export; we are confident we will be competitive thanks to the support of the regional government and the skilled workforce in Batam," Hashim stated during the plant's groundbreaking.

Investing in Intellectual Property

Aryo emphasized that the center’s contribution goes beyond balance sheets. By developing tech in-house, the company ensures that "national intellectual property" remains in Indonesian hands.

"This is our contribution not just for downstreaming, but also for investment in R&D and in intellectual property that will belong to the nation’s children," Aryo stated. The project marks a turning point where Indonesian firms transition from being labor providers to becoming technology owners in the competitive global electronics arena.
