 Abstract
 Arabica coffee leaves is one of the natural ingredients containing flavonoids which have the potential as antibacterial. This study aims to determine the antibacterial activity of facial wash gel preparation of ethanol extract of Arabica coffee leaves in inhibiting the growth of Cutibacterium acnes. Facial wash gel was made with a concentration of 20% arabica coffee leaf ethanol extract in several formulas with various gelling agents, namely carbopol, HPMC, Na CMC 10% and 30% respectively. Inhibitory activity of facial wash gel preparation of ethanol extract of arabica coffee leaves on Cutibacterium acnes bacteria using well diffusion method. The results of the diameters of the antibacterial inhibition of the formulas F1, F2, F3, F4, F5 and F6 respectively were 22.85 mm, 22.87 mm, 22.30 mm, 22.45 mm, 22.93 mm and 22, 26mm. It can be concluded that all formulas have strong category inhibition against Cutibacteriumacnes bacteria and based on the results of one-way ANOVA statistical analysis shows that there is no significant difference in the gelbase variation on the inhibition of facial wash gel for all formulas (P>0.05)
