Abstract
Sea cucumber Paracaudina australis has high value of nutrition and high potential economically for increasing trading of others fish productions. This research has purpose to study of proximate content, profile of amino acid and profile of fatty acids. The samples of P. australis were taken from Kenjeran Waters, Eastern Part of Surabaya. The result showed that P. australis had contain high protein (20.22%), very low contain carbohydrate (0.86%), ash (2.58%), total fat (1.42%) crude fiber (0.51%) and very high percentage of moisture (74.92%). The profile of amino acid was dominated non essential amino acid such as glutamine acid (1.06 g · (100 g)–1), glycine acid (0.85 g · (100 g)–1), aspartic acid (0.60 g · (100 g)–1). Sea cucumber P. australis had contain some essential amino acid such as leucine, histidine, lysine, threonine, arginine, valine and isoleucine. There were very few procentage of fatty acid, Oleat acid C 18:1 omega 9 (0.0537%). The profile of fatty acid from P. australis were dominated by oleat acid C18:1 and palmitate acid C 16:0.
