Kappa-carrageenan, derived from red seaweed, is well-known for its excellent film-forming properties and widely used as a bioplastic material. It possible to improve the physical mechanical of bioplas-tics by mixing kappa-carrageenan with cassava peel starch polyvinyl alcohol (PVA) reinforcement. The goal this study find best combination bio-plastic based on thickness, tensile strength, elongation, water vapor transmission rate (WVTR), specified in JIS Z 1707. A completely randomized block design (CRBD) was employed varying ratios waste starch. findings show that mixtures had big effect all bioplastic's properties, except density. All formulations met standard strength elongation. Higher con-centrations significantly improved barrier reducing WVTR absorption. However, increasing concentration enhanced elongation while decreasing Young's modulus, resulting slower biodegradation. mix, which 4% 1% kappa-carrageenan, thickest at 0.35 mm, 1.14 MPa, an 25.78%, 18.47 g/m²/day (Grade 3). results can be make bioplastics meet standards properties. This could also help reduce plastic pollution future.
