Conventional plastics produce waste that was difficult to decompose and needed to substitute with starch-based bioplastics. Sago consist of 27-35% amylose and 50-73% amylopectin, which have the potential to be used as a material for starch-based bioplastics. This study aims to determine the optimal value of Microcrystalline Cellulose (MCC), citric acid and sorbitol for the characteristics …
