    This experiment was aimed to making plasticizer from oil of waste catfish and isobutanol. Oil of waste catfis have high potential to developed as alternative raw material for making plasticizer for substitution petroleum. To process oil of waste catfish to be plastisizer can be used transesterification reaction with H-zeolite as catalyst and isobutanol as an alcohol. Transesterification oil of waste catfish using agitation reactor with reaction time as long 5 hours. The studying variation in this experiment are molar ratio (catfish oil: isobutanol) and agitation speed. After running the experiment got conversion increase by elevated molar ratio, while the increase of agitation given an unsignificant conversion. The highest conversion reached is 74,8% by using molar ratio oil to isobutanol is 1:12, agitation speed is 175 rpm and catalyst concentration is 10 wt% at temperature reaction 102 . The physical properties of isobutyl ester were produced by transesterification reaction confirm with standard plastisizer comercial and from analysis product by using GC-MS showed that not all product conversion to be isobutyl ester, the product just have isobutyl laurate, isobutyl caprate and isobutyl stearate with each value of concentrasion are 1,83%, 4,93% and 2,35%
