Formulation And Antibacterial Activity Of Liquid Soap Of Sago Leaves Extract (Metroxylon Sago Rottb) Against Staphylococcus Aureus And Escherichia Coli Bacteria.

Abstract

Liquid soap is a skin cleansing formulation made from soap- based ingredients with addition of other permitted compound and can be used for bathing without causing irritation to the skin. One of the plants that has antibacterial activity is sago leaf (Metroxylon sago rottb) which contains various active compounds such as alkaloids, flavonoids, saponins, phenols, tannins, and steroids. This study aims to formulate the liquid soap preparations of ethanol extract of sago leaves with concentrations of 5 %, 10 %, and 15 % against the growth of Staphylococcus aureus and Escherichia colim bacteria.This study using laboratorium experimental method with the concentrations of ethanol extract (Metroxylon sago rottb) made into liquid soap formulations. Stability test were carried out including organoleptic tests, pH test, Foam height test, moisture content test, homogenity and
viscosity test. Antibacterial testing was carried out using agar diffusion by means of wells. The results of the physical stability test, the liquid soap preparation with concentrations of 10 % and 15 % met the standard of nationally Indonesia (SNI), namely organoleptic test, pH test, Foam height test, water content test, homogeneity and viscosity test. The result of antibacterial activity test of sago leaf ethanol extract liquid soap could inhibit staphylococcus aureus bacteria at concentrations of 5 % (13.30 mm), 10 % (12,73 mm) and 15 % (11.30mm), and Escherichia coli at concentration 5 % (12.83), 10 % (13,53 mm) and 15 % (15.10 mm) are strong categories.
