Abstrakt: Synthesis of chitosan from the scales of starry trigger fish has been carried out in three stages: deproteination using 10% NaOH solution, demineralization using 0.63 M HCl solution, and deacetylation using NaOH solution with three different concentration of NaOH, those were 60%, 50%, and 40% NaOH. Characterization of synthesized chitosan showed that the best chitosan was obtained by deacetylation process with 60% NaOH. The degree of deacetylation obtained 74% has met the DD standard of at least 70% chitosan. Ash level 88.05%; 6% water content; 2.29% protein content. [ABSTRACT FROM AUTHOR]
