The Examination of The Quality of Chitosan from Bamboo Shell Waste with Variations of NaOH Concentration in the Deacetylation Proces

Abstract

The bamboo shells that have been unused will be thrown away. Bamboo shell waste is still not utilized
or processed optimally, better processing and utilization are needed so that the waste does not pollute the
surrounding environment. Bamboo shells can be used as chitosan. The main organic material found in the
mollusca animal group contains organic material that forms chitin and chitosan compounds. This study aims
to determine the quality of chitosan from bamboo shell waste with variations in NaOH 60%, 65%, 70%, 75%.
Analysis of research data using simple regression test. The results of quality inspection of bamboo shell
chitosan showed that yield and degree of deacetylation obtained significance of p = 0.03 and 0.01 (p<0.05) so
NaOH effect on yield quality and degree of deacetylation, water content and ash content are significant p =
0.21 and 0.20 (p>0.05) so NaOH has no effect on the quality of water content and ash content. The conclusion
of this study is chitosan from bamboo shells has the quality standards of SNI 7949 in 2013. Suggestions for
other researchers are to add other variables and parameters, while for industry use chitosan as an absorbent for
heavy metals, cosmetics, food preservatives.
