Abstract
Cooking oil consumption in Indonesia is very high and tends to rise every year, reaching 500,000 tons / year. Therefore, used cooking oil is used to reduce waste cooking oil by reprocessing through purification using activated charcoal to remove color and odor. This study aims to determine the effect of NaOH concentration on the quality of soap with used cooking oil as a raw material from purified activated charcoal. This study was designed using an experimental method with descriptive analysis. The treatment in this study was the difference in NaOH concentrations of 10%, 30%, and 50% with each concentration repeated three times. The effect of NaOH concentration on soap quality was tested through the ANOVA test. The results obtained show that the most optimal NaOH concentration is 50% because it has a dense soap consistency. While the 30% NaOH concentration has a semi-solid soap consistency. At 10% NaOH concentration the consistency of soap is still liquid. It can be concluded that the concentration of NaOH affects the quality of the soap.
