FORMULATION AND PHYSICAL QUALITY TESTING OF SOLID SOAP COMBINATION OF CITRONELA OIL (Cymbopogon nardus) WITH EXTRACT BAJAKAH TAMPALA (Spatholobus littoralis Hassk) AGAINST BACTERIA Staphylococcus aureus

Abstract

to the skin. Citronella oil and Bajakah Tampala are plants that possess antibacterial activity and can be used as raw materials for the production of solid antibacterial soap. This study aimed to determine the physical quality characteristics of citronella oil solid soap with a combination of Bajakah Tampala extract and perform an antibacterial activity test. The method employed was experimental, involving the formulation of solid soap and several preliminary tests such as organoleptic testing, pH testing, homogeneity testing, and foam stability testing. Antibacterial activity tests were conducted using the disc diffusion method. The results of this study indicate that the addition of citronella oil and Bajakah Tampala extract to solid soap influenced the antibacterial activity against Staphylococcus aureus, exhibiting a very strong inhibitory effect in Formula 3 at 100%. In the physical quality testing of the solid soap formulation, the results were in accordance with the Indonesian National Standard (SNI). The conclusion of this research is that the physical quality characterization of the soap is in line with established standards, and the solid soap formulation has proven antibacterial activity.
