Rare earth metals (Logam Tanah Jarang/LTJ) are currently a strategic commodity. Utilization of rare earth metals is closely related to high-tech industrial products, such as the computer, telecommunications, nuclear and aerospace industries. The use of LTJ will be widespread, especially single rare earth elements, such as neodymium, samarium, europium, gadolinium. Currently, energy is no longer just a form of fossil fuels, uranium, plutinoum, wind and water. LTJ is even categorized as an energy reserve. LTJ is also considered as an important material in the future.

Badan Geologi Kementerian Energi dan Sumber Daya Mineral (ESDM) conducts a survey and mapping of rare earth element mineral potentials in Indonesia. As a result, there are 28 locations that have been identified as having potential for LTJ. Sumatra Island is the location with the most potential for LTJ with 16 points, followed by Kalimantan with 7 points, Sulawesi with 3 points and finally Java with 2 potential points. The hypothetical resource in Sumatra is around 23 million tons with the LTJ laterite deposit type, along with 5 million tons of the LTJ with the tailings type. Meanwhile in Kalimantan, LTJ’s hypothetical resource is around 7 million tons with the tailings type and in Sulawesi about 1.5 million tons with the laterite type. These resources are still hypothetical and inferred, so they need further exploration.

Even the Kepala Badan Geologi, Eko Budi Lelono, revealed that the Lapindo mudflow in Sidoarjo, East Java was also identified as having the potential to contain LTJ. The potential content of LTJ is also found as an associated mineral in mining commodities, including coal in Kalimantan. The regulatory framework in terms of development and utilization is indeed needed and is immediately prepared starting from regulations under the Kementerian Energi dan Sumber Daya Mineral to downstream processing in the industrial sector as regulated in the UU Minerba.

LTJ producing countries such as China have begun to limit and reduce exports of rare earth metals (LTJ). This is an opportunity for researchers at universities and research institutions to develop LTJ, because this is needed by advanced industries today and in the future.

In order to develop ITS mission of contributing to science and technology for the welfare of society through education, research, community service and management activities based on information and communication technology, the Research Center for Science, Material, and Nanotechnology ITS presents WEBINAR Potential and Rare Earth Metal Processing Strategic Minerals and Energy of the Future with the aim of bringing together LTJ stakeholders and designing an understanding between stakeholders.
