Conventional plastics made from synthetic polymers have non-biodegradable properties that cause environmental problems. This study aims to compare the characteristics of biodegradable plastics based on cassava starch, durian seed starch, and purple sweet potato starch. Film production was carried out using a blending method with varying chitosan concentrations (0; 1; and 2%). Characterizations carried out included tensile strength, elongation, swelling, air solubility, and biodegradation tests. The results showed that the type of starch and chitosan concentration significantly affected the mechanical and physical properties of biodegradable plastics. Purple sweet potato starch plastic had the highest tensile strength, the lowest swelling and air solubility values, but the slowest biodegradation rate. Cassava starch plastic showed balanced mechanical and degradation characteristics. Meanwhile, durian seed starch plastic had the lowest tensile strength, the highest swelling and air solubility values, but the fastest biodegradation rate.
