The research studied properties of biodegradable film from the mixture of sago starch and chitosan. The biodegradable film was obtained by solution casting method with addition of glycerol 1.5% as plasticizer. Mechanical properties of biodegradable film from sago starch and chitosan were determined including tensile strength, elongation, color and biodegradability. To study shape surface morphology of biodegradable fllm, the microfracture of biodegradable film was observed by scanning electron microscopy (SEM). Biodegradable film with the composition of sago starch and chitosan 1:1 signiflcantly had the lowest number of tensile strength. The study revealed that addition of chitosan improved biopolymer elongation and brightness, hut it weakened tensile strength of biopolymer and reduced its biodegradability.
