MetadataShow full item record
The formulation of kecombrang flos extract (Etlingera elatior (Jack) R.M.Sm.) liquid bath soap has been established. The objective of this research was to formulate liquid bath soap of kecombrang flos extract (Etlingera elatior (Jack) R.M.Sm.) and to test its antibacterial activity to Staphylococcus aureus. Kecombrang flos extract was extracted by maceration method using 96% ethanol, and followed by minimum inhibitory concentration (MIC) test using hole method. Concentration variation of kecombrang flos extract was conducted as F1 (6%), F2 (8%), and F3 (10%). The formula of liquid bath soap of kecombrang flos extract was evaluated using several examinations such as organoleptic, pH, viscosity, density, foaming stability, antibacterial activity test, irritation test and hedonic test. The result shows the liquid bath soap of kecombrang flos extract F1, F2 and F3 can inhibit the growth of Staphylococcus aureus. Based on statistical test using SPSS 21 (for trial) ANOVA method continued by LSD shows that F0 (negative control), F1, F2, F3 and positive control (triclosan 2.5%) have difference meaningful result with significance value < 0,05.
