Abstract
One of problems faced by cocoa farmers is waste cocoa beans that can not fulfill market standard. Ecological problems above could be principle back to nature by application it to make soap based fat cocoa apkir and a ginger extract. The purpose of this research was to determine the optimum consentration of oleoresin needed for the reaction with cocoa afkir fat during the bar soap making qualified to SNI and provides a relaxing effect. The treatments in this study were the addition of ginger extracts 5%, 10% and 15%. Observations on the soap were including chemical properties, physical properties, and organoleptic test. The results of the analysis showed that all soap formulas met the requirements of solid soap SNI 3532:2016 for water content, residual free alkali, and unsoluble raw materials. The formula of soap with addition of ginger extract 10% was the best product with organoleptic test test results reached 2,64 with color, aroma, texture, foam, and warm effect attributes that can be used for relaxation. The analysis results of those soap were 9,85 of water content, 0.08% of residual free alkali, 0.412% of unsoluble raw materials in etanol, pH value of 10.5, hardness 2.7224 N, the foam stability of 1.5 cm. This technology could be applied in the production of soap with the addition of ginger extract and to be developed into some industrial scale.
