The effectiveness of adding antioxidant compounds from pedada leaves extract (Sonneratia Caseolaris) in antiseptic soap production

Pedada leaves (Sonneratia caseolaris) are plants from tropical areas with relatively high antioxidant content. This research aims to make antiseptic soap with the addition of pedada leaves and see the quality of the antiseptic soap by SNI 03-3532-1994. This research includes the pre-treatment process, namely taking pedada leaf extract by maceration using ethanol and acetone solvents using a variety of evaporation tools in the form of a water bath and soxhlet, then making soap with coconut oil with variations used in the form of evaporation methods and the amount of extract used. This research analyzed water content, free alkali, and free fatty acids. The observations showed that using a water bath would produce a more significant amount of extract. The results of the soap-free alkali analysis produced ranged from 0.061% to 0.088%, which shows that the free alkali content is still below the limit determined by SNI. The lowest water content analysis results obtained were 11.30%.
