Temugiring (Curcuma heyneana) contains flavonoid and curcumin compounds that have the potential as sunscreen. Therefore, the extract concentration added in the cream formulation must be determined precisely since it may affect the Sun Protection Factor (SPF) value. This research aims to determine the effect of concentration variations of temugiring extract on the SPF value of the temugiring extract cream. In this research, ethanol extract temugiring were obtained by maceration employing ethanol. Then, temugiring extract obtained was formulated in cream formulations with variations in the extract concentration 5%, 7.5%, and 10%. Furthermore, the SPF value was conducted using the UV-Vis spectrophotometry method. The results show that concentration variations of temugiring extract produced different SPF values for each cream formula. The SPF value for formulas 1, 2, and 3 was 3. 307±0.11; 3.497±0.18; 4.966±0.24. Therefore, it can be concluded that the concentration variations of temugiring extract affect the SPF value and creams with concentrations of temugiring extract 5%; 7.5%; and 10% have the potential as sunscreens with minimal until moderate categories.

The concentration of bangle (Zingiber cassumunar) ethyl acetate fraction added in the formulation of the temugiring (Curcuma heyneana) extract cream formulation must be determined precisely since it may affect the Sun Protection Factor (SPF) value. This research aims to determine the effect of concentration variations of bangle ethyl acetate fraction on the SPF value of the temugiring extract cream. In this research, temugiring extract and bangle extract were obtained by remaceration employing ethanol, while the bangle ethyl acetate fraction was obtained by fractionation using n-hexane, ethyl acetate, methanol, and water. The bangle ethyl acetate fraction obtained was formulated in cream formulations of temugiring extract formulas 1, 2, and 3 with variations in the concentration of bangle ethyl acetate fraction 2%; 3%; and 4%. Furthermore, the SPF value was conducted using the UV-Vis spectrophotometry method. The results show that bangle ethyl acetate fraction concentration variations produced different SPF values for each cream formula. The SPF value for formulas 1, 2, and 3 was 11.466; 12.122; and 17.266. One Way ANOVA test produced a p-value of 0.037. Thus, it can be concluded that the concentration of the bangle ethyl acetate fraction would affect the SPF value in the cream temugiring extract.
