Abstract

Ketepeng (Cassia alata) is a wild plant that is traditionally recognized as a medication for skin diseases. The leaf of Ketepeng has a phytochemical content that plays a role to inhibit the growth of Eschericia coli. A transparent soap with an addition of leaf extract is one of the innovations to increase the economic value of the Ketepeng plant. This research aims to identify the effect of adding leaf extract on the quality of transparent soap based on the Indonesian National Standards (SNI). The experiment design that used is Completely Randomized Design (RAL) with a three-time repetition. It comprised three different treatments consist of the addition of leaf extract as much as 2, 4, and 6 grams in 50-gram coconut oil as the basic material of soap. The result of this research indicated that increasing the concentration of leaf extract might increase saponification value, hardness, pH, inhibition zone of Eschericia coli ATCC 25922. It was also reported to increase the attribute texture of the transparent soap, as well as to decrease water content, foam stability, free alkali, and soap transparency. The best treatment in this study was the transparent soap which was added by 6 grams of ketepeng leaf extract.
