Abstract
Effervescent drink is defined as a dosage form that produces carbon dioxide bubbles as a result of chemical reactions in solution. In this study, effervescent beverages will be made from a mixture of sappan wood and red ginger. The purpose of this study was to determine the effect of citric acid and sodium bicarbonate concentrations on the characteristics of effervescent powder of red ginger and sappan wood mixed drinks and to determine the best treatment of citric acid and sodium bicarbonate concentrations that produce effervescent products with the best characteristics and favored by panelists. This study used a completely randomized design (CRD) factorial pattern with two factors and three replications. Factor I is the addition of sodium bicarbonate concentration consisting of three levels, namely 32%, 34%, 36%. Factor II is the addition of citric acid concentration, namely 1.5%, 2%, 2.5%. If there is a significant difference, it will be continued with the DMRT 5% further test. The best treatment results were obtained in the treatment of adding sodium bicarbonate concentration of 34% and the treatment of adding citric acid with a concentration of 2.5% which produced a moisture content of 7.905%, pH value of 5.98, dissolving speed of 1.47 minutes, antioxidant activity of 40.672%, total phenol 0.366mg GAE/g, total titratable acid 3.36% and color (111), scent (132), taste (142.5).
