Abstract

Indonesia coal resources have been updated annually. The most recent data (2003 publication) shows that the total Indonesian coal resource is 57,847.74 million ton. This number can be classified as 12,466.42 million ton measured resources, 20,533.56 million ton indicated resources, 24,314.96 million ton inferred resources, and 532.80 million ton hypothetical resources.

Data for coal resources calculation derived from government inventory reports as well as private company reports. The main problem appears in coal resources compilation is there is no standard format in reporting Reserves and Resources of coal in their concession area. Although the government has already published the National Standard (Amendment 1 - SNI 13-5014-1998) for Coal Resources and Reserves Classification, most of private companies have not applied the standard yet. Therefore, there is no certainty for classified coal resources. Moreover, most of the coal companies (both private and BUMN) never reported the total reserve of their exploration areas. This would affect the compilation on Indonesia coal resources.

It is suggested that the government should make guidance for reporting the coal Resources and Reserves. The government also should insist coal companies to follow this guidance. Regarding resources and reserves classification, the government should strongly socialize the standard for coal resources and reserves to coal business sector (private companies, institution, as well as universities).
