Daftar Isi:
- The consumption of palm cooking oil in Indonesia is very high, and as a result, the used cooking oil (UCO) which is mostly end up as the waste is also high. Direct discharge of UCO into environment causes serious environmental pollution problems. UCO contains triglyceride and free fatty acid, which can be converted into biodiesel. In this study, the conversion of UCO into biodiesel was conducted using subcritical methanol method. The effect of the process parameters such as the ratio of UCO to methanol, temperature, and pressure on the yield of biodiesel was investigated. Based on the Response Surface Method; temperature, pressure, and UCO to methanol ratio gave significant effect on the FAME yield. From the experimental result, the maximum FAME yield obtained was 88.43% with the purity up to 97% (180°C, 45 bar, 3:10), while the maximum yield calculated by RSM was 88.8115% with the optimum condition: 174.7°C, 45 bar for UCO to methanol ratio 3.263:10. The components in the FAMEs product are Undecanoic Acid Methyl Ester (C11:0), Myristoleic Acid Methyl Ester (C14:1), cis-10-Pentadecenoic Acid Methyl Ester (C15:1), Stearic Acid Methyl Ester (C18:0), Oleic Acid Methyl Ester (C18:1n9c), Elaidic Acid Methyl Ester (C18:1n9t), cis-8,11,14-Eicosatrienoic Acid Methyl Ester (C20:3n6), Heneicosanoic Acid Methyl Ester (C21:0), Arachidonic Acid Methyl Ester (C20:4n6), cis-5,8,11,14,17-Eicosapentaenoic Acid Methyl Ester (C20:5n3), Erucic Acid Methyl Ester (C22:1n9) cis-13,16-Docosadienoic Acid Methyl Ester (C22:2) Tricosanoic Acid Methyl Ester(C23:0).
