Quality of Bioplastic Made From Tofu Waste Starch With Variations of Glycerol Using the Melt Intercalation Method

Abstract Bioplastics are plastics made from natural (organic) materials and are renewable and easily degraded by nature. This type of research is quantitative research with a laboratory experimental approach with variations in glycerol volume (ml) as the independent variable and bioplastic quality as the dependent variable. The results showed that there were color gradations in each treatment and variations in glycerol volume had an effect on thickness, tensile strength, elongation, elastic modulus, water absorption and bioplastic degradation. Bioplastics made from starch waste starch for each treatment meets JIS-2-1707, ASTM-D-6002 and SNI 7818:2014 standards on parameters of thickness, tensile strength and degradability
