In a typical case, explains luthfi fatah, a resource coal, a fossil fuel energy resource, plays an important role in the economic development of a country and thus, research on the sustainability of long-term coal supply is a continuous challenge, be it the amount of future supply and time of peak production. this study focuses on the outlook and forecasting of indonesian coal production. the scope of analysis includes current and future mineral and coal mining activities are governed under the law on mineral and coal mining no.42009 dated january 2009 this law replaces the predecessor mining law no. which provided the framework for all of indonesias pre-2009 mining concessions including all of the existing cows and coal cows
