<p align= "justify">Coconut is one of the potential natural resources in Indonesia. The main fatty acid contained in coconut oil is lauric acid (~50%), followed by myristic acid (~18%) and palmitic acid (~9%). Lauric acid can be converted into its alcohol e.i. lauryl alcohol, which is used as raw material in detergen industry, such as soaps, cosmetics, and other cleaners. In this research, lauric ester resulted from the trans-esterification process of triglyceride of coconut oil, obtained from the previous research, was reduced using reductor agents zinc borohydride {Zn(BH4)2} and lithium aluminium hydride {LiAlH4} to form lauryl alcohol. Chromate test results from both procesess indicated the formation of primary alcohol. While the absorption peaks of the infrared spectra of the two products at 3450-3300 cm-1, which is assigned to the –OH vibration, and absorption at 2900-2950 cm-1 which is believed to be due to methylene group (-CH2) vibration of long chain, confirmed the formation of long chain primary alcohol. Quantitative analysis was performed for both processes by extraction and by conducting GCMS measurements, which resulted in 19,63% lauril alcohol from reduction with Zn(BH4)2 and 26,15% from reduction with LiAlH4.<p align= "justify">
