        abstract = {This study aimed to synthesize and characterize starch-based bioplastics from two abundant sources, cornstarch and potato starch, and evaluate the effects of glycerol content, acetic acid concentration, and pH on their physical and chemical properties. Nine bioplastic samples were prepared by solution casting with varying compositions of starch, glycerol(1-10ml), and acetic acid (0–10%), followed by neutralization and drying. The films were characterized through visual inspection and absorption tests in water, acetic acid (5%), and sodium hydroxide (0.1N) solutions. Potato starch-based bioplastics exhibited higher flexibility but greater water absorption (up to 112.8%) compared to cornstarch-based films. Increased glycerol content enhanced elasticity but also increased hydrophilicity. Samples synthesized with higher acetic acid concentration or without neutralization showed significantly elevated water and acid absorption. All samples demonstrated lower absorption in alkaline medium than in acidic medium. The properties of starch-based bioplastics can be effectively tailored by adjusting the starch source, plasticizer content, and synthesis pH. While potato starch offers better flexibility, cornstarch provides greater stability in moist environments. Optimization of these parameters is crucial for developing bioplastics suitable for specific applications such as biodegradable packaging.},
