ABSTRACT
Used cooking oil is frying oil that contains carcinogenic compounds such as free fatty acids, peroxides and others. To utilize used cooking oil, researchers are interested in recycling used cooking oil by carrying out a purification process using wood charcoal powder as an adsorbent. After the purification process, the oil is used to make liquid bath soap. This study investigates the effect of adding KOH concentration in the manufacture of liquid soap from used cooking oil and measuring pH, free alkali, specific gravity and organoleptic properties of the resulting liquid soap. This research method begins with the process of purifying used cooking oil by preparing a sample of wood charcoal powder, then activation using 20% KOH soaked for 24 hours. The used cooking oil purification process uses wood charcoal as an adsorbent with a mass of 12 g and a particle size of 60 mesh. Furthermore, the purification process is carried out using the adsorption method. The results of the purification of used cooking oil are used to make liquid soap using various concentrations of KOH 6.5%; 7.5%; 8.5% and 10% as reagents at 80℃ heating temperature. The soap paste obtained was then melted and mixed with 100 ml of distilled water heated at 40℃ until the soap paste became liquid. The resulting liquid soap was tested such as pH, free alkali content, specific gravity and organoleptic based on SNI for liquid bath soap. The best liquid soap is to use 10% KOH where pH 10,9 is obtained, free alkali is 0.078%, specific gravity is 1.011, liquid soap is milky white in color, has a characteristic soap smell and is liquid in shape.
Keywords: Adsorbent, Potassium hydroxide, Cooking oil, Liquid bath soap.
