Boyke Raymond Toisuta, Bustami Ibrahim, Sugeng Heri Suseno

Fisheries production volume increased to 345.130 ton in 2011 (KKP 2012). The favorite and abundant product is smoked fish. Smoked fish processing is very traditional, and produces considerable waste. 40-60% waste are usually dumped directly to sewage system. The study objective are utilization of tuna wastecharacteristic. The result showed the first phase had a total yield of 35.08%. The nutrient content are moisture (head 76.33%), fat (gonads 3.83%), protein (skin 24.08%) and ash (head 5.66%). The heavy metals residue were still inside the safe thresholds of Indonesian National Standard., The identification of fatty acids obtained 30 types of fatty acids. The highest content of SFA are palmitic acid (18,09%) recovered from the head, MUFA are oleic acid (11,96%) also recovered from the head, and PUFA are DHA (30,10%) recovered from gonad. By-product from gonad also have the best yield for fatty acid as much as 68,75%.
