The Concentration of polyethylen glycol (PeG) 400 on bioplastic cellulose based carrageenan waste on biodegradability and mechanical properties bioplastic

Abstract

An additional ingredient is needed in making bioplastics to increase the elasticity value, namely plasticizer Polyethylene Glycol 400. This study aims to determine the effect of the application of Polyethylene Glycol (PeG) 400 as a plasticizer in cellulose-based bioplastics from carrageenan-making waste to biodegradability and to determine the best concentration of Polyethylene Glycol (PeG) 400 on cellulose-based bioplastics on its mechanical properties. This activity was carried out from January to March 2020 in the Laboratory of Chemical Analysis of the Faculty of Fisheries and Marine Airlangga University. Data is collected by an experimental method that is by direct treatment, as well as by literature study. Experimental research used ANOVA data analysis and followed by DMRT. The results of this study indicate that the effect of PeG 400 was significantly different (P <0.05) on the ability of biodegradation with the highest value of 38.56% % for 7 days at a concentration of 4 ml. Based on the literature, the addition of PeG 400 by 30% is the best and produces a tensile strength value of 0.083 MPa.
