Karakterisasi Bioplastik dari Pati Sukun (Artocarpus Altilis) dan Carboxy Methyl Cellulose (Cmc) dengan Plasticizer Gliserol

Abstract

Bioplastic obtained from breadfruit starch (Artocarpus altilis) and carboxy methyl cellulose (CMC) with increasing of glycerol as a plasticizer was carried out by varying the addition of glycerol at concentration of 10%, 20%, 30% and 40% of the starch weight by heating at 60 oC. The bioplastic produced were tested for tensile strength, percent elongation, percent water absorbed, degradability and FT-IR. The characterization results showed that the optimum bioplastic film on Starch : CMC with a glycerol concentration of 10% with the resulting values being tensile strength of 34.26 N/mm2, percent elongation of 21,4%, percent of water absorbed 44% and biodegradability of 20% in 32 days. The results of the analysis of the characteristics of the FT-IR spectrum showed the groups contained in the bioplastic film of breadfruit starch and CMC with glycerol plasticizer contain functional groups with C=O and C-O-C bonds which are easily degraded.
