ABSTRACT Bioplastic is plastic made of renewable raw materials. Bioplastic can be made by utilizing sago starch and cellulose from waste such as pineapple leaf fiber cellulose. Bioplastic also require glycerol to increase elasticity and reduce fragility of bioplastic. This study aims to obtain the right amount of glycerol to the characteristized bioplastic from sago starch and pineapple leaf f…
