Bioavtur is avtur substituent as an aircraft jet engine fuel. The use of bioavtur has been regulated in Minister of Energy and Mineral Resources Regulation No. 25 of 2013 which states that the use of bioavtur as aircraft fuel is required to be 2% in January 2016. However, so far Indonesia has not been able to produce bioavtur independently so that the bioavtur used is still 100% imported with a total value reached IDR 1.48 trillion in 2017. This research aims to synthesize bioavtur. The metal hydroxide mixture is prepared by the coprecipitation method. Metal base soap is made according to the method described in the modified Patent Akers (1984). Metal base soap is then decarboxylated in a glass reactor to produce liquid hydrocarbons. Liquid hydrocarbons are analyzed by gas chromatography and their composition is determined. The results gathered indicated that soap with ?=0,25 and decarboxylation temperature of 400°C gave the best result in terms of avtur yield and selectivity.
