Evaluation of Potency and Mineral Reserve Balance for Sustainable Mining Management Case Study: Central Java Province of Indonesia

The level of availability and scarcity of resources gives an indication of how to manage scarce resources. Good mining practice supports sustainability and minimizes environmental degradation. One alternative to support the development of potential mineral resources is the study of mineral resource balances. The research objectives are: (a) to evaluate the potential of mineral resources and reserves, (b) to evaluate the production data of mineral commodities, (c) to calculate mineral reserve balance. Research methodology includes an inventory of data in the Department of Energy and Mineral Resources. Compilation of mineral resource balance adjusted to the applicable regulations. The study was conducted in the Central Java Province of Indonesia. Based on the evaluation results there were 26 mineral commodities, but there were only 12 commodities developed during 2016-2018. These resources are andesite, limestone, basalt, fill-dirt, sandstone, trass, feldspar, quartz-sand, marble, diorite stone, talk and claystone. The mineral reserve supports the construction of highways, airports and other infrastructure projects in Central Java Province of Indonesia.
