Abstract

Research has been carried out on the effect of potassium hydroxide catalyst concentration on the yield of coconut oil (Cocos nucifera) transesterification and continued to characterize the reaction results. The concentration of potassium hydroxide used was 1, 2, and 3% by weight of coconut oil with ethanol as the reactant. The data processing used was the one-way analysis of variation and its characterization from a physicochemical perspective, followed by the analysis of gas chromatography-mass spectroscopy (GCSM) and infrared spectrophotometry. Based on the data processing results, potassium hydroxide concentrations of 1, 2, and 3% did not affect the yield of the transesterification reaction of coconut oil, and the results were 74.5264%, 71.9330%, and 69.0420%. The characterization results show that the physicochemical properties of the reaction products, such as acid number, density, and viscosity, comply with the Indonesian National Standard (SNI) for biodiesel. The results of the GCMS analysis showed that nine peaks were dominated by ethyl laurate.

Abstract

Coconut oil is one of the vegetable oils widely used in the food, cosmetic, and pharmaceutical industries due to its high content of saturated fatty acids, particularly lauric acid. This study was conducted on the effect of coconut oil processing methods on the characteristics of the resulting coconut oil. Three processing methods were applied: non-heating, fermentation, and direct heating. A transesterification step was carried out to determine the fatty acid profile and its derivatives. The characterization of coconut oil compounds included measurements of density, acid value, peroxide value, and ester value, as well as analysis of fatty acid compounds using Gas Chromatography-Mass Spectrometry (GC-MS). The results showed that the best method for producing coconut oil was the non-heating process, with the following physicochemical properties: yield of 13.5%, acid value of 0.20 mg KOH/g, peroxide value of 2.00 meq/kg, and ester value of 223.28 mg KOH/g. The main components identified from the transesterified coconut oil were dodecanoic acid methyl ester (methyl laurate), methyl tetradecanoate, and hexadecanoic acid methyl ester.
