The energy crisis of fossil fuels has become a problem due to its limited availability and to cause global warming. The use of bioavtur is an effort to develop an alternative renewable fuel and to reduce global warming gas emissions for around 15% in the aviation sector. Sunan pecan oil is a non-edible oil that is more attractive because it does not need to compete with food sources and is easily converted into bioavtur fuel. Sunan pecan oil-based methyl ester converted into bioavtur product through ozonolysis bubbling process does not produce much pollution and has a high selectivity. This research aims to develop the bioavtur production process from sunan pecan oil using an agitated ozonolysis reactor. Study on the effect of ozon flowrate (5, 10, 15, 20 L/min) on ozonolysis reaction products was carried out by measuring density, acid value, and kinematic viscosity. The results showed that the higher the ozon flowrate, the smaller the density, acid value, and kinematic viscosity of bioavtur product. The decrease in density means that the medium chain methyl esters formed are lighter in specific gravity. While the decline in acid numbers is related to breaking of unsaturated bonds by penetration of ozone molecules. The hydrogen bonding of free fatty acid products is getting weaker, therefore the viscosity of ozonolysis products is also decreases. The density produced from ozonolysis (795-804 kg / m3) has a characteristic density at 15 ° C for aircraft fuel according to ASTM 1655 of 775 - 840 kg / m3, The acid number and acid value produced from ozonolysis ranged from 0,5-0,8 mg KOH/g and 0,597-1,045 cP at 26°C.
