Indonesia should position itself inside the global semiconductor supply chain rather than watching from outside it, according to Nezar Patria, a deputy minister at the communications and digital ministry. Speaking at a discussion in Jakarta, he argued that the country's mineral wealth is leverage in the competition over artificial intelligence, and that the leverage is currently being exported.

The specific asset he names is silica sand, the raw material for the silicon wafers from which chips are made. Indonesia, he says, holds an estimated 340 million tonnes of it, and at present ships much of that sand to China, Europe and Japan for processing.

From sand to wafers, and the distance between

The gap between a reserve and an industry is the whole story. Turning silica sand into semiconductor-grade silicon requires purification to a tolerance measured in parts per trillion, then crystal growth, wafering and fabrication — a chain of capital-intensive plants, each of which needs stable power, treated water and a workforce that does not yet exist at scale in Indonesia. The deputy minister acknowledges that domestic semiconductor manufacturing still relies heavily on imported components, and that the country is not yet part of the global chain.

His plan is downstream processing: stop exporting the raw material, map the resources the industry needs, and look for partner countries that already have the technology. That is the same downstreaming logic Indonesia applies to nickel and bauxite, and it is easier to state than to finance.

The reserves figure is the government's own estimate. Missing from the account are the purity of the deposits, the cost of the power and water a wafer plant would need, and any committed investor. On those, the pitch is still at the stage of ambition.
