Bioplastics are environmentally friendly plastics derived from natural materials. Bioplastics are easier to decompose when compared to commercial plastics. Bioplastics are generally made from starch contained in plants. But the use of starch as a base material has the disadvantage of producing bioplastics that are not waterproof. Therefore, it is necessary to add chitosan to improve bioplastic characteristics. Chitosan usually comes from the shell of crustacean animals, but it turns out that in fish scales waste, also contains chitosan. Fish scales are a by-product of the process of fish processing. Fish scales are only discarded and not utilized so that they become waste that can pollute the environment. Fish scales have a chitin content that can process into chitosan, which can be useful as an additional ingredient in the manufacture of bioplastics. This review aims to find out the potential of fish scales waste as chitosan in the manufacture of bioplastics. Based on the results of previous research, fish scales have a chitosan content that can use as an additional ingredient in the manufacture of bioplastics. Fish scale chitosan can form bioplastic film with characteristic brownish-yellow film. The addition of fish scale chitosan is also able to improve the water resistance of bioplastic film. Based on the results of the review can be concluded bring fish scales to have the potential as chitosan that can use in the manufacture of bioplastic.Keywords – Bioplastic, Chitosan, Fish Scales.

“…Derajat deasetilasi meningkat seiring dengan bertambahnya suhu dan waktu deasetilasi. Fadli et al (2015) menyatakan bahwa semakin tinggi suhu pemanasan dan lama waktu reaksi, maka akan semakin tinggi juga derajat asetilasi. Banyaknya molekul NaOH yang ter-adisi kitin dipengaruhi oleh kenaikan waktu reaksi, sehingga menyebabkan makin banyak pula gugus asetil yang terlepas.…”

Chitosan is a white amorphous solid chitin, and of high biological and mechanical characteristics.Chitosan production is divided into two stages. First is chitin isolation (deproteination, demineralization,and depigmentation), and second is deacetylation of chitin to chitosan. This research was aimed to determinethe characteristic of chitosan isolated from the shells of the white leg shrimp using different temperatureand time in the deasetilation process. The FTIR test results showed that the chitin group was partiallybroken into chitosan in every treatment. The highest content of chitosan was obtained at the temperaturetreatment of 100oC for 2 hours, while the highest degree of deacetylation, viscosity, and molecular weightwere observed at the temperature treatment of 120oC for 3 hours. The sample were not soluble in aquades,methanol, or ethanol indicating the samples were chitosan.

Shredded shrimp production is still classified on a small scale with insufficient human resources, traditional technology, and an inadequate managerial system making weaknesses in business development experienced by the Sumber Rejeki Sejahtera Group. The purpose of this study is to formulate a priority strategy in developing shredded processing business. The method used in this research is a case study by conducting interviews using a questionnaire. Analysis of business development strategies using TOWS (Threats, Opportunities, Weakness, and Strengths) and QSPM (Quantitative Strategic Planning Matrix) approaches. The results of this study in the form of priority strategies in the development of dried shredded shrimp using QSPM analysis are to increase promotional activities, expand distribution and marketing networks to maintain product quality, product development, optimize business production volume, improve services to consumers and distributors, improve the quality of human resources.
