Abstract: Plastic waste pollution has become a significant environmental challenge, thus development of sustainable and biodegradable alternatives from waste materials are important. This study focuses on the development of bioplastic using banana peel as the primary material, chitosan as a filler, and glycerol from waste cooking oil as a plasticizer. The objective was to enhance the mechanical properties of bioplastic by incorporating chitosan extracted from crustacean shells through a green extraction process, including demineralization with citric acid, deproteinization using bromelain from pineapple peel, and deacetylation with avocado seed extract. Bioplastic films were formulated with 2% chitosan and characterized for tensile strength and modulus young. Results showed that using the waste materials, bioplastic was synthesized successfully. Bioplastic with 0% and 2% chitosan have tensile strength of 0.513 MPa and 0.247 MPa, and Young’s modulus of 138 MPa and 49.8 MPa, demonstrating improved flexibility but not strong compared to unmodified banana peel bioplastic. The addition of chitosan contributed to better structural reinforcement, making the material more durable and adaptable for practical applications. This study confirms that bioplastic from banana peel and chitosan have significant potential for biodegradable packaging applications. The findings contribute to the advancement of biopolymerbased materials, supporting global efforts to reduce plastic waste and promote environmentally friendly solutions.
