Abstract : Plastics, the most widely used packaging material, have become a major environmental concern due to their non-biodegradability and adverse effects on ecosystems. To address this issue, biodegradable films made from natural starch, such as cassava peel starch, have emerged as eco-friendly alternatives. This study investigates the impact of incorporating carrageenan and sodium tripolyphosphate (STPP) into cassava peel biodegradable films. Carrageenan enhances tensile strength, while STPP improves the film matrix. Tensile strength increases with higher starch concentrations but decreases elongation. FTIR and SEM tests confirm the formation of new functional groups and denser structures, meeting quality standards. These findings provide a foundation for optimizing cassava peel starch edible film formulations. The research utilized a variety of tests and analyses, including tensile strength, elongation, FTIR, and SEM, to explore the mechanical properties and structural changes in cassava peel starch biodegradable films. The results demonstrated the potential for these films to serve as sustainable alternatives in packaging and various applications.
