The increase of virgin vegetable oil price has contributed the problems to the biofuel
manufacturing industry. An option with great potential is used cooking oil recycling, which includes a variety
of processes like pyrolysis and catalytic cracking, designed to transform waste cooking oil into hydrocarbon
products for use in the preparation for refined chemicals or fuels. This research aims to determine some
properties of used cooking for the production of biofuel. Preliminary analysis of used cooking oil properties
via GCMS using capillary column shows n-Hexadecanoic acid and Oleic acid as the major compounds
present in the used frying oil. The analysis for determination of volatile and moisture content with 3 replicates
show an average of 0.02% moisture and volatile content, which the experimental procedure was based on
