<P><B>Abstract</B></P> <P>Lipase can be produced from Aspergillus niger using solid state fermentation method. This research aimed to produce lipase in powder form. The highest activity unit (38.67 U/g) was obtained from rice bran substrate at 5th day with inducer concentration of 2%. The best drying method to produce dry extract with activity unit of 566.67 U/g was freeze drying with maltodextrin additive. The best drying method to produce fine powder with activity unit of 333.33 U/g was spray drying with skim powder additive. Supernatant and powder lipase worked optimally at 30 <SUP>&deg;</SUP>C with activity unit of 44.00 U/g and 355.56 U/g respectively.</P>
