Transesterifikasi Minyak Ikan Perak (Mene maculata) Dengan Katalis CaO Dari Cangkang Telur Ayam
Transesterification of Silver Fish Oil (Mene maculata) with CaO Catalyst from Chicken Egg Shells
Abstract
Silver fish (Mene maculata) is a type of pelagic fish found in the Moluccas sea, this fish has a high oil content so that it is easy to extract the oil content for transesterification. The transesterification reaction of oil from silver fish oil needs a catalyst, and heterogenous catalyst is a better choice. This study was determined the fatty acid methyl ester composition of M. maculata by transesterification process using heterogeneous CaO catalyst from chicken egg shells through 3 steps i.e. oil isolation, CaO catalyst synthesis, and oil transesterification reactions. Oil isolation was carried out by soxhletation method using petroleum ether with the oil content was 13.51%. Synthesis of CaO catalyst was carried out by calcination at 1000 °C for 2 hours and then charactererized by XRD. Fish oil is transesterified using CaO catalyst in a ratio of 11% (w/v) of the mixture. Furthermore, fatty acid methyl esters obtained were analyzed using GC-MS. The results showed 6 methyl ester fatty acids as composition of transesterification products which were methyl myristic (11.85%), methyl palmitoleate (8.71%), methyl palmitic (25.13%), methyl oleic (9.49%), methyl stearic (10.04%), and methyl 5,8,11,14-eikosatetraenoate (1.96%).
