This research aimed to get the combination of drying temperature and dextrin concentration against the quality of temulawak’s essence, and the combination between citric acid and Na- Bicarbonate treatment against temulawak’s effervescent powder quality. The result of the first step shows that the treatment combination between 20% of dextrin concentration and 50°C of drying temperature which is the best treatment of the first step from temulawak’s powder essence that has characteristics on 10.11% of water content, ( L*) 55.10 of brightness level, (a*) 14.56 of redness level, ( b*) 44.20 of yellowness level, 24.63% of rendement, 5.63 of pH; 2.78 of water re-absorption; 1.88% of sugar content reduction; 62.27% antioxidant content, 5.55 obtains panellists’ assessment against color, 5.95 of taste, and 4.15 of aroma. The result of the second step shows that the treatment combination between 10% citric acid and 20% Na-bicarbonate that is the best treatment of the second step that has characteristics on 7.48% of water content, (L*) 59.37 of brightness level, (a*) 14.53 of redness level, (b*) 46.50 of yellowness level, 5.33 of pH, 88.17 of dissolving rate, 2.49% of sugar content reduction, and 46.53% of antioxidant content. The conclusion of this research is the best treatment combination on the first step is 20% of dextrin concentration and 50°C drying temperature, while at the second step is 10% citric acid concentration and 20% Na-bicarbonate. The advice of this research is its necessary to analyze the curcuminoid content as an active antioxidant compound in temulawak.
