Electricity supply in Java Bali has increased with the operation of the Java 7 Unit 1 Steam Power Plant (PLTU) since the end of 2019. The coal-based PLTU located in Serang, Banten Province is the largest PLTU in Indonesia with a total capacity of 2×1,000 Megawatts (MW). This PLTU is the first large power plant in Indonesia to use Ultra Super Critical (USC) boilers which can increase the efficiency of the plant up to 15 percent higher than non-USC. USC technology also makes the resulting emissions lower so that it is more environmentally friendly. In addition to boiler technology, PLTU

PT Amman Mineral Industri’s (AMIN) copper smelter project continues to show significant progress. After entering the commissioning stage, this national strategic project is getting closer to the commercial production stage. As a form of support for the success of this project, PT Nusa Bahari Perkasa has sent its first fleet to transport Silica Flux commodities. This important raw material will be used in the smelter commissioning process and will later become one of the main components in the copper smelting process. This strategic partnership between Amman Mineral and Nusa Bahari Perkasa not only strengthens the domestic supply chain, but also

Steam Power Plants (PLTU) play a vital role in meeting Indonesia’s electrical energy needs. However, to ensure efficient and environmentally friendly PLTU operations, the availability of raw materials such as limestone is crucial. Limestone, or limestone, has an important function in the desulfurization process at PLTU. This mineral material is able to absorb sulfur dioxide produced by burning coal, thereby reducing emissions of harmful pollutants into the air. The abundance of limestone reserves in Indonesia is a distinct advantage for the country. However, the distribution of this raw material from mine sites to power plants requires complex and reliable logistics.
