Proses Pembuatan Methyl Ester (Biodisel) dari Minyak Kelapa Menggunakan Katalis Naoh Konsentrasi Rendah Dengan Bantuan Gelombang Mikro (Mikrowave)

Abstract

Research production process of methyl ester (biodiesel) from coconut oil using NaOH Catalyst with Microwave-assisted Transesterification in the background backs by the energy crisis that requires a new method to create renewable energy in this case is biodiesel. The purpose of this research is to study the process of making biodiesel with microwave radiation method, the effect of the catalyst concentration of NaOH, the influence of power, heating time used to the yield and viscosity of biodiesel produced. Production of methyl esters (biodiesel) from coconut oil carried by oil mole ratio: methanol = 1: 9. Biodiesel is then analyzed to the viscosity test, flash point test, and gas chromatography (GC). The optimum yield in the manufacture of methyl esters (biodiesel) from coconut oil with microwave-assisted method for the transesterification catalyst is NaOH concentration of 0.25% with a power of 400 watts and a reaction time of 4 minutes.
