Abstract<br />Indonesian capture fisheries production reached ± 6.4 million tons in 2014. This number was predicted<br />resulted a huge fishery waste, one of them was swim bladder that potentially contain collagen, so it needs to<br />be developed. This aim of this study was to determine the characteristics of the swim bladder (proportion<br />and chemical content) and collagen characteristics (yield and physicochemical properties) extracted from<br />the swim bladder cunang (Muraenesox talabon). Swim bladder waste had proportion 0.57 to 0.67% of whole<br />yellow-piked conger body weight and 24.74% protein/100 g wet weight (equivalent to 93.39% of protein/100<br />gram dry). The waste had a potency of collagen, which is characterized by the high proportion of the<br />amino acids glycine, proline, hydroxyproline and alain. Acid extraction and hydrothermal process resulted<br />collagen extracts, identified from a spectrum of amide I, amide II and amide III functional groups. Collagen<br />extracted with acid process contained a higher glycine than hydrothermal one, but instead hydrothermal<br />process produced extract with a higher proline, hydroxyproline and alanine composition.<br /><br />
