Abstract
Abstract The carrageenan industrial waste materials can be used bioplastic biodegradable production because has high cellulose content 71.38%. Bioplastics can easily degraded and flexible, it is necessary to add glycerol plasticizers, that can reduce internal hydrogen in intermolecular bonds that affected biodegradability and mechanical properties of bioplastics. This study aimed was to analyze the effect of glycerol application as plasticizers on bioplastics based carrageenan waste cellulose on biodegradability and analysis the best concentration of glycerol on bioplastics to get biodegradation standards and mechanical properties based on the review article. This research was experimental in testing biodegradability of carrageenan waste cellulose bioplastic with the addition of glycerol (1; 3; 5; 7% v/v) and review article on the mechanical properties of bioplastics and waste cellulose content. Experimental research used ANAVA data analysis and followed by DMRT. The results of this study were indicated that the glycerol has significantly effect (P <0.05) on the ability of biodegradation with the highest value of 39.20 + 0.87% - 40.34 + 0.78% for seven days at a concentration of 5-7%. Based on the review article, the concentration of glycerol on bioplastics cellulose that suitable with biodegradation standards and mechanical properties of bioplastics is 5%
