ABSTRACT
Agarwood leaf extract is able to inhibit the growth of Bacillus subtilis and Pseudomonas aeruginosa in order to prevent the skin infections. The ability of agarwood leaf extract to inhibit microbial growth can be applied to a liquid soap. The study aimed to determine the effect of agarwood leaf extract addition in the quality of liquid soap and its inhibitory effect on the growth of Bacillus subtilis and Pseudomonas aeruginosa bacteria. The study used complete randomized design with five treatments and four replications. The treatments were addition of agarwood leaf extract volume in consecutive S0 (0%), S1 (2,5%), S2 (5%), S3 (7,5%), and S4 (10%) in the liquid soap formulations. The data was statistically using Analysis of Variance and continued with Duncan’s New Multiple Range Test at 5%. The result showed that addition variations of agarwood leaf extract in making of the liquid soap significantly effected on free alkali, degree of acidity (pH), foam stability, density of liquid soap, antibacterial activity test, and sensory of the liquid soap. The selected treatment from this study was S4 (10% addition of agarwood leaf extract). Liquid soap from this treatment had 0.057% free alkali, 9.33 degree of acidity, 89.79% foam stability, 1.08 g/ml of specific gravity, 24.86 mm antibacterial activity against Bacillus subtilis and 22.16 mm antibacterial activity against Pseudomonas aeruginosa. The result of descriptive test on the liquid soap showed that the soap had dark brown color and agarwood leaf flavor. Keywords: agarwood leaf extract, antibacterial activity, Bacillus subtilis, liquid soap, Pseudomonas aeruginosa
