OPTIMASI FRAKSI MASSA ALKALI DALAM PEMBUATAN SABUN MINYAK JELANTAH DAN UJI KUALITASNYA

ABSTRACT: This study focuses on the optimization of alkali mass fraction in the manufacture of used cooking oil soap and its quality testing with variations in alkali mass of 7.5; 8; 8.5; and 9 grams. This study aims to optimize the alkali mass fraction in the manufacture of solid soap from used cooking oil and evaluate its chemical quality and organoleptic characteristics. Four types of used cooking oil were used with variations in NaOH mass of 7.5; 8; 8.5; and 9 grams. Before the saponification process, the oil was tested for its peroxide value using the iodometric titration method to determine the oxidation level. The resulting soap was then tested based on SNI 3532:2021 including water content, pH, and insoluble materials in ethanol, as well as foam stability and organoleptic tests. The average peroxide value of used cooking oil was 16.89 meq O₂/kg. The best soap had a water content of 13.65%, a pH of 9.22, and insoluble materials of 0.57%, all of which met the standards. The foam stability of 58.33% indicates a fairly good foaming ability. The organoleptic test showed the highest level of preference at an alkali mass fraction of 0.17, namely 8.5 grams using oil 1, with a percentage of aroma of 76%, color of 76%, texture of 76% and hardness of 68%. Keywords: Used cooking oil, solid soap, alkali mass fraction, peroxide test, organoleptic
