Abstract
Indonesia has the potential for abundant coal reserves. According to data from the Ministry of Energy and Mineral Resources in 2011, the total amount of Indonesian coal is estimated at 119.4 billion tons, of which 48% is located in South Sumatra with 70% of the coal deposits being brown or low quality coal. coal that is still affordable and cheap. Behind the selection of coal there are still some drawbacks from using coal directly. One of them is that coal releases gas (CO2, N2O, NOx, SOx and Hg) which causes global warming and pollution. Coal gasification is a process for converting solid coal into a gas mixture that has a fuel value (Triantoro, A., 2013). Coal gasification will produce producer gas in the form of synthetic gas (syngas) with the main components consisting of carbon monoxide (CO), hydrogen (H2), and (CH4). By converting coal using gasification as a clean energy producer, a blower as a regulator of air flow, cyclone as a tar separator and a gas cooler. Based on the results of testing the variation of coal used, the 5515 Kcal / Kg variation of coal experienced a rapid rise in temperature and was able to produce a flame for 115 minutes. with the composition of Syngas CO and CH4 of 12.4% an 1.2% while the variation of coal 4640 Kcal / Kg produces the highest H2 of 6.9%. Coal 5515 Kcal / Kg produces the largest percentage of syngas conversion, carbon conversion, LHV and Power Output, 13.46%, 70.397%, 2.427 MJ/Kg and 18.403 KW
