FORMULATION AND CHARACTERISATION OF GRANULE EFFERVESCENT CILEMBU SWEET POTATO(IPOMOEA BATATAS (L) LAMK)EXTRACT WITH CONCENTRATION VARIATION OF CITRIC ACID AND SODIUM BICARBONATE

Abstract

Nowdays there are many people interested in consuming traditional drugs because of the chemical compound. Effervescent granule extract cilembu sweet potato is made from citric acid, tartaric acid, sodium bicarbonate, saccharum lactis, PVP (Polivinylpirolidone), extract cilembu sweet potato. The purpose of this study to determine the effect of varying concentrations of acid and alkaline source to the physical quality of effervescent granules. The through is use dry granulation method.There are three variations of the formula one of them with a citric acid concentration of 4.7%, 4.3%, 3.9%. Tartaric acid concentration of 9.4%, 8.6%, 7.8% and 11.7% base concentration, 12.8%, 13.8%. Evaluation extracts include organoleptic test, test-free ethanol, qualitative test. Evaluation of the physical quality of the granules include organoleptic test, test flow properties, the test angle of repose, solubility test, pH test. Research result show that average pH 4,3., average angle of repose 25,42o., average flow properties 0,740gram/detik, solubility 1 minute second 10 . Data were analyzed by One Way ANOVA test. Statistic data show that there is no meaningfull difference and significance standart p >0,05.
