BIODEGRADABLE PLASTICS FROM STARCH OF COLOCASIA ESCULENTA (Diah Permata Sari, 2014, 42 page, 6 tabel, 8 picture, 4 attachment) Taro (Colocasia esculenta) is a plant that has low economic value and also underutilized because of taro (Colocasia esculenta) contains calcium oxalate which causes GATA-itching and irritation of the skin. Therefore taro (Colocasia esculenta) can be used as raw material for biodegradable plastics. This study was conducted to determine the addition of sorbitol to obtain better quality plastic (optimum conditions). In this study conducted by varying sorbitol as much as 20%, 30%, 40%, 50% and 60% of the weight of starch. The results showed that the lower the composition of sorbitol is used then the resulting plastic is getting hard and stiff, and conversely the more the composition of sorbitol are used then the resulting plastic will be soft and easily crushed. Sorbitol concentration can best be used to produce biodegradable plastics is at a concentration of 20% and 60% which has a thickness of 0.45 mm,% elongsitas of 1.9% and 0.98% and the tensile strength test of 0.0004 MPa and 0, 0038 MPa Keyword : Colocasia esculenta, Sorbitol, Biodegradable Plastic
