Utilization of Japanese Seeds and Soybean Seeds as Raw Materials for Making Flour

The accumulation of plastic waste and excessive use is a common environmental issue in Indonesia. Plastics are synthetic polymers that stable, water-resistant, light, flexible, strong, but very difficult to be broken down by microorganisms. Decomposition burning can cause other issues during the combustion process produce dioxin compounds harmful health. An available affordable alternative reduce using bioplastics. Bioplastics plastics made from natural materials microorganisms, so they more environmentally friendly than commercial plastics. Generally, main ingredients making bioplastics starch or chitosan. source used this project comes cassava peel waste. In project, researchers also utilize chicken egg-shells. function adding eggshell give biodegradable hard characteristics. ratio between egg shell was 1:0, 1:1, 1:3, 1:5. With 1:1 most optimal. addition shells with right (1:1) ability biodegradation increase. results Tensile Strength Test Bioplastic Samples 1:3 1:5 9.2 x10-3 kgf/cm2, 4.4 2 kgf/cm2 x10 -3 kgf/cm2.
