Abstract

Fresh fish samples were divided into three parts (A, B, and C). Sample A,weighing 109.83 g, was extracted by maceration method using petroleum ether as a solvent. Sample B was extracted oil by roasting, while sample C was extracted by means of oil extraction. Analysis of fatty acid content and the levels in the sample using GC-MS. The results obtained are the oil content in the sample as much as 1.637%. Sample A contained 3 fatty acid component compounds, namely tetradecanoic acid methyl ester with a concentration of 3.56% and retention time of 13.032 minutes, 9-hexadecenoic acid methyl ester with a concentration of 2.04% and retention time of 15.191 minutes, and hexadecenoic acid methyl ester with levels of 7.84% and retention time of 15.395 minutes. Sample B contains 3 fatty acid component compounds, namely propanoic acid methyl ester with a concentration of 0.27% and retention time of 1.520 minutes, butanoic acid dimethyl ester with a concentration of 1.34% and retention time of 3.599 minutes, and hexadecanoic acid methyl ester with a concentration of 0 ,67% and retention time 15.394 minutes. While sample C contains 6 fatty acid components,namely tetradecanoic acid methyl ester with a concentration of 5.60% and retention time of 13.033 minutes, 9-hexadecanoic acid methyl ester with a concentration of 4.38% and retention time of 15.189 minutes,hexadecanoic acid methyl ester with a concentration of 17.90% and retention time of 15.394 minutes, 9-octadecanoic acid methyl ester content of 1.97 % and retention time of 17,315 minutes, 11-octadecanoic acid methyl content of 1.42% and retention time of 17.370 minutes, and methyl octadecanoic acid content of 5.49% and retention time of 17.550 minutes. The same type of fatty acid contained in the three samples, namely, hexadecanoic acid.
