【 摘 要 】

Cassava peel (Manihot utilissima) is waste of agricultural result that is much potential as raw material of bioplastic making. This research focuses on bioplastic making from cassava peel. It aims to characterize the resulted bioplastic (mechanical and physical properties, SEM analysis, FTIR analysis and time test of bioplastic degradation). The bioplastic preparation takes place by mixing starch of cassava peel and chitosan (20, 30, 40 and 50% w/w), glycerol 30% w/w as plasticizer, and liquid smoke (0, 1 and 2 mL) as antimicrobial agent. The research result shows the highest value of tensile strength is 96.04 MPa, the highest elongation at break is 52.27%, and the value of water-resistant test is 22.68%. Morphology analysis by using SEM shows uneven surface and there is fracture in its cross-section. The analysis of functional group by FTIR shows the presence of functional groups of O-H (hydroxyl), N-H (amine), dan CH3-O (ether). The fastest complete degradation of bioplastic occurs in 45 days, and the longest occurs in 57 days.
