Barracuda is one type of fish that is widely used in the diversification of processing fishery products. This business will increase the amount of waste if it is not managed optimally. This study aims to utilize fish skin and head bones as raw material for collagen, which can reduce the amount of fish processing waste and provide added value to the waste. Barracuda skin and head bones that will be used as a raw material in the manufacture of collagen are first characterized by analysis of the chemical composition of the skin, which includes water, ash, protein, fat content. This chemical composition analysis aims to assess the initial feasibility of barracuda skin and head bones as raw material for collagen. The results of proximate analysis of the skin and head bones of barracuda (Sphyraena jello) showed a water content of 67.39%; 22.56%, ash content 2.53%; 58.45%, protein content 21.69%; 14.32%, and fat content of 8.38%; 4.58%. Barracuda skin and head bones are still fresh in terms of the value of water content that is still in the range of water content of the skin and head bones in general. High protein levels in the skin compared to head bones barracuda allows it to be used as raw material for collagen. Barracuda skin and bone fat levels are high enough, so pretreatment needs to do to remove fat and minerals so that it can improve the quality of collagen produced.
