Study on optimal conditions for pigment production from Monascus purpureus TISTR 3090 on adlay solid state fermentation was carried out using Central Composite Design (CCD) with three parameters: moisture (x1: 50 60 and 70 percent), pH (x2: 5.5 6.0 and 6.5) and temperature (x3: 25 30 and 35 deg C) The result indicated that the most significant factors influencing pigment production were pH and temperature. The optimum conditions for pigment production was 58-63 percent moisture, pH 5.95-6.25 and 28-31deg C which pigment production was 105 OD units/g. dry weight at 10 days fermentation.
