Inhibition of Carica Solid Soap to the Growth of Staphylococcus epidermidis Bacteria

Abstract

Carica (Carica pubescens Lenne & K. Koch.) contains various nutrients such as vitamins, minerals, and active substances that can be used for skin care, and to bath soap products. The purpose of this research was to determine the inhibition of Carica soap to the growth of Staphylococcus epidermidis bacteria. The method used in this study was agar diffusion. Samples in this research were 12 Carica soaps with different formulation, and a control using papaya soap that has been circulating on the market. The results of the study were analyzed using ANOVA with a confidence interval of 5 %. The results showed that the significance value was 0.472 > 0.05 so there was no significant difference between the soap formulations on the inhibition zone of the S. epidermidis bacteria. The highest inhibitory zone is in soap with formula 1 (1.38 cm), the lowest inhibitory zone is in soap with formula 7 (1.1 cm), while the papaya soap inhibition zone (positive control) is 1.7 cm. Suggestion from this research is to reformulate Carica soap to improve its quality.
