Abstract
Eel (Anguilla sp.) is a highly nutritious Indonesian marine commodity. However, information on the eel nutrient content in Indonesia is still limited. This study was aimed to determine chemical properties of Indonesian eels,Anguilla bicolor bicolor and A. marmorata. Proximate, amino acid, fatty acid, and vitamin A analysis were carried out on the fresh eel. The A. bicolor bicolor ontained 65.51% of moisture, 1.34% of ash, 16.78% of protein, 13.26% of fat, and 3.1% of carbohydrate. Meanwhile, results on A. marmorata showed it contained 57.17% of moisture, 1.09% of ash, 17.30% of protein, 21.35% of fat, and 3.12% of carbohydrate. Leucine and glutamic acid represented the highest essential and non-essential amino acid of both A. bicolor bicolor and A. marmorata, respectively. The highest saturated and monounsaturated fatty acid were palmitate and oleic acid for A. bicolor bicolor as well as A. marmorata. The content of vitamins in A. marmorata was higher than in A. bicolor bicolor.

Analisis yang dilakukan yaitu kadar proksimat, komposisi asam amino, komposisi asam lemak, dan vitamin A pada ikan segar. Kandungan proksimat pada A. bicolor bicolor yaitu kadar air 65,51%; abu 1,34%; protein 16,78%; dan lemak 13,26%. Hasil proksimat pada A. marmorata yaitu kadar air 57,17; abu 1,09%; protein 17,30%; dan lemak 21,35%. Ikan sidat memiliki kandungan gizi yang tinggi terutama vitamin A, E dan asam lemak tak jenuh (EPA dan DHA) (Seo et al 2013). Penelitian mengenai komposisi asam amino dari A. bicolor bicolor dan kandungan proksimat, asam amino, asam lemak, dan vitamin A dari A. marmorata di Indonesia belum dilaporkan, sehingga perlu dilakukan penelitian terhadap karakterisasi ikan sidat ini. Penelitian ini bertujuan untuk menentukan karakteristik sidat jenis A. bicolor bicolor dan A. marmorata yang terdiri dari kandungan proksimat, komposisi asam amino, komposisi asam lemak dan vitamin A
