Abstract

Cassava leaves contain flavonoids, saponins, polyphenols, alkaloids, and steroids that act as antibacterial substances. The use of liquid soap in the community is preferred over other soap dosage forms. The use of SLS as a surfactant in soap formulations can irritate the skin, so cocamide DEA is used to reduce skin irritation. The advantages of cocamide DEA are it can produce good foam, is stable at room temperature, and can be used on sensitive skin. This study aims to determine the physical characteristics of liquid soap ethanol extract of cassava leaves and antibacterial activity on the growth of Staphylococcus aureus. This research is experimental with various extract concentrations, namely 1%, 3%, and 5%. Parameters tested were organoleptic test, pH test, homogeneity test, foam height and stability test, viscosity test, and antibacterial test. The results obtained include the percentage of cassava leaf yield of 16.57%; the highest pH test was 7.50 (F1) and the lowest was 7.0 (F1); the highest test of foam height and stability was 82.36% (F3) and the lowest was 75.01% (F1); the highest viscosity test was 306.2 cPs (F1) and the lowest was 143.6 cPs (F3); organoleptic test is in accordance with the requirements of SNI. Based on the test, the better formula is F3 (5%) and the antibacterial test has not shown any inhibitory power against Staphylococcus aureus.
