Abstract

The location of research is located in the Tanjung Baru Area, Lahat Regency, South Sumatera. The Geological
setting of the Tanjung Baru Area in the South Sumatra Basin is included in the Muara Enim Formation the age
is Middle Miocene to Late Miocene. Coal in the Tanjung Baru Area, has a calorific value of 5089-5321 Kcal
/ kg and is rank High in Bituminous Volatile C-High Volatile Bituminous B according to the ASTM
classification. Average quality (proximate test) of Muara Enim Formation coal: total sulphur 0.36 -1.49%
(adb); 1.28-2,5% ash (adb); inherent moisture 9-11% (adb); volatile matter 38.7-42.4% (adb); fixed carbon
45.5-47.9% (adb), total moisture 28.1-28.8% (Ar); relative density 1.28. Coal Charactersitics of Coal Tanjung
Baru the macerals average are vitrinite (92,4% vol.); liptinite (2.9% vol.); i nertinite (5,7% vol.). Each
macerals or group macerals has different physical and chemical properties. The variation of composition
microscopy showed the changes of plant communities or coal facies leading to varies of coal quality, with a
average vitrinite reflectance value 0.47-0.58, generally the coal rank is subbituminous-bituminous. Coal
gasification is the process of converting coal into synthesis gas. One of the gas produced is a flammable
methane gas. Gasification is raw fuel, in this case coal is partially oxidized to produce a product called
combustible gas. The main product from the gasification product is synthesis gas or syngas, consisting of
Carbon Monoxide (CO), Hydrogen (H2), Methane (CH4), Carbon Dioxide (CO2) and Nitrogen (N2).
