Waste Cooking Oil (WCO) has potential as biodiesel feedstock since it contains triglycerides. However, it contains many impurities and requires several purifications. Thus, this study aims to evaluate the feasibility of WCO as a biodiesel feedstock in the term of physicochemical properties such as free fatty acid content (%FFA) as palmitic acid, moisture content, and peroxide number. Samples are collected from fast-food fried chicken restaurants in Padang, West Sumatera, Indonesia. WCO is processed by filtering, degumming, centrifugation, neutralization, and adsorption. FFA content, moisture content, and peroxide number are examined based on ISO 660, ISO 665, and ISO 3960, respectively. The finding shows that WCO has 2.01%FFA, 0.65% moisture content, and 1.02 mg O2/100g peroxide number. These findings show that WCO is feasible as biodiesel feedstock after several purifications. The results of this study are expected as the basic information in biodiesel production by using waste cooking oil as biodiesel feedstock. © Published under licence by IOP Publishing Ltd.
