    Abstract: Gasification attract smore interest recently since it offers 
  higher conversion efficiency and low pollution generated. Equivalence ratio 
  is parameters for control gasification performance. The purpose of this study 
  is to evaluate gasification rubber wood in conventional updraft gasifier. In 
  this study, the equivalence ratio is varied from 0.21-0.31 according to obtain 
  temperature distribution, gas composition, LHV of the gas, cold gas efficiency 
  and tar content produced. The highest of LHV the gas reachs of 4.2 MJ/m<SUP>3</SUP> 
  with cold gas efficiency of 75% and tar content of 140 g/m<SUP>3</SUP> at equivalence 
  ratio of 0.31.
