Abstract
The skin is an organ that covers the entire human body, and has the power of protection against outside influences. One type of skin disorder that often occurs is acne. One of the common bacteria that infects acne is Staphylococcus epidermidis. Based on these problems, researchers are interested in making liquid soap preparations of starfruit extract (Averrhoa bilimbi L) which contain tannins, alkaloids, saponins and steroids/triterpenoids which have antibacterial activity. The ethanolic extract of starfruit was extracted by maceration using 96% ethanol solvent, then the preparation was formulated using various concentrations of 0%, 8% 12% 16%. The physical quality of liquid soap was tested for organoleptic, foaming power, pH, viscosity, homogeneity, stability, and antibacterial activity against S. Epidermidis. Antibacterial activity was tested using the well diffusion method. The data obtained were then processed statistically with the Shapiro-Wilk test. The results of the research on liquid soap formulations with ethanol extract of star fruit (Averrhoa bilimbi L) had good physical quality tests, and poor stability, but still met the predetermined standards. The liquid soap preparations of star fruit extract at concentrations of 8% and 12%, had inhibitory diameters of 16.66 mm and 19.33 mm in the strong category, and a concentration of 16% with an inhibitory diameter of 20.55 mm in the very category. strong. Keywords : Liquid soap, star fruit extract (Averrhoa bilimbi L), Staphylococcus epidermidis, antibacterial activity
