Head of the Minerba Conservation Working Group/Mining Inspector of the Directorate General of Mineral and Coal Donny P. Simorangkir said that domestic coal consumption growth was relatively low. "It's not comparable to the production growth rate of national coal mining companies," he said during the Coal webinar on the Metallurgical Industry Downstream Strategy for National Competitiveness, Friday (11/12/2021). Until now, he continued, 50.3 percent of PLN's electrical energy sources still come from PLTU as the cheapest energy.

On the other hand, demands to reduce global warming and environmental issues continue to increase in addition to the slow development of renewable energy sources.

Even so, coal-fired power plants are considered to be relatively small. Indonesia accounts for 1.62 percent of PLTU power plants from the world's total. In addition, the use of domestic steam power plants is still relatively new compared to European countries which are now starting to abandon this commodity.

"The implementation of coal conservation efforts in the framework of good mining engineering principles needs to be done through optimizing coal reserves to support the guarantee of the availability of domestic coal, especially steam power plants, industry, textile cement, smelters to downstream industries."

Special Staff of the Minister of Energy and Mineral Resources for the Acceleration of Governance in the Minerba Sector Irwandy Arif said that currently six coal gasification plants will be built to produce syngas, DME methanol and ammonia. As well as four semi-coke and activated carbon factories.

"This needs to be accelerated because the products produced are to reduce the need for imports of basic chemicals," he said.

From the downstream plan, the ministry aims for PNBP and taxes to be US$136 trillion and can save the country's foreign exchange up to Rp140 trillion in 2045.

In 2020, the Directorate General of Mineral and Coal of the Ministry of Energy and Mineral Resources recorded non-tax state revenues (PNBP) of IDR 34.6 trillion. Achievement increased by 110 percent from the target of Rp. 31.41 trillion

Meanwhile, the realization of PNBP in the Minerba sector until the third quarter of 2021 has reached Rp49.67 trillion. This figure jumped 127 percent from the target until the end of this year, which was Rp. 39.1 trillion

According to data from the Ministry of Energy and Mineral Resources, Indonesia has coal resources and reserves of 144 billion tpn and 39 billion tons, respectively. This amount is predicted to last up to 70 years with an average production of 570 million tons per year and domestic absorption of around 132 million tons.
