<![CDATA[Waste from fish scales, skin and bones in the fishing industry are currently only used as fish meal or handicrafts. Fish waste is very abundant, especially in fish that are widely consumed by the public, such as little tuna or Kawakawa (Euthynnus affinis). Therefore, innovations are needed in processing fish scales, skin and bones waste, namely as ingredients in making fish glue. Fish glue is an adhesive resulting from the extraction of fish scales, skin and bones which contains collagen, which can be hydrolyzed in hot water and dilute acid to form fish glue. The aim of this research is to determine the effect of using fish skin, scales and bone waste materials on the results of glue products. The research method is by extracting bones, scales, and skin of Kawakawa using 5% CH3COOH solution in a ratio of 1: 1, then filtered to obtain fish glue. This study used two treatments: the use of raw materials of bones, scales, and fish skin (Sample-1) and fish skin and scales only (Sample-2). The results of research showed that Sample-2 showed a higher total rendement or yield than Sample-1. In addition, Sample-2 has a more intense color than Sample-1. It is necessary to demineralize the raw materials (fish waste) to increase the results of collagen extraction.]]>
