Biomass gasification is a topic that is currently popular technology which convert biomass to another form of energy. Unfortunately, gasification has many challenges specially to reduce tar in significant amounts which will be discussed in this journal. Regular updraft gasifier can produce 10%-30% volatile tar while many gasifiers produce so much tar that gas cleaning cost is more than the actual gasifier. In-situ method is used for reducing tar amount inside the reactor. One of the solutions is inverted downdraft gasifier implementation, which typically produces much less tar, about 1-5%. In this research, the inverted downdraft gasification was simulated by Aspen Plus which provides an overview optimal condition for less tar syngas. The result gives us highest value of syngas, 6,05 MJ/Nm3 for Coal and 6,24 MJ/Nm3 for MSW(Municipal Solid Waste) which both of them have ER 0,20. In Aspen Plus, we can discover several main parameters that can be done by finding both mass flow rate and contents in syngas which contains CH 4, H 2, CO, CO 2, O 2, H 2 S, N 2 and H 2 O.
