ABSTRACT: People has been used
juicy tuber as food and cosmetic for delicated skin. Juicy tuber extract was
formulated in cream in order to practical and effective. The aim of this
research is to know the influence of difference concentration of juicy tuber
extract in cream and storage duration to its physical properties. Extract was
obtained from juicy tuber by remaceration method using 70% ethanol. Cream were
made in five formulas with extract concentration 0,5 %, 1,0 %, 1,5 %, 2,0 % and
2,5 % w/w using standard formula cold cream. The physical stability of the
cream was tested such as homogeneity, creaming and cracking, stickness, and
spreadibility for 4 weeks storage. The data obtained were statistically
analyzed using Friedman test with the 95 % confident level, followed by Mann
Whitney test. Result of this research indicate that the cream of juicy tuber
