Abstract

Chitosan is a polysaccharide compound produced by deacetylation of chitin shells in batik shells. Batik shells in Kendal are often found in the waters of Rowosari Kendal. the many benefits of chitosan, such as natural food preservatives, are the basis for further research derived from of batik shells.The one of benefit ingredients of batik shells is chitin and chitosan. The purpose of this study is to preliminary test batik shells is chitin and chitosan. This method is experimental with a population of all batik shells in Rowosari Kendal, a sample of in part of the batik shells with the criteria obtained from Rowosari, Kendal. This research was conducted in the Kendal STIKES laboratory. Experiments with repeated on average experiments 5 times later. The research treatment is the post test only design which is divided into 3 groups. The test group was given chitosan batik shells with concentrations of 25%, 50% and 75%. The results were then analyzed using univariate statistical analysis in the form of an average of chitin yield, an average of chitosan yield and a standard deviation. This result preliminary test in this study indicate the presence of chitosan compounds. The average yield of chitin shells is 89.88 ± 0.022, while the average yield of chitosan shells of batik shells is highest at a concentration of 75% w / v of 7.53% w / v.
