The increase in plastic production worldwide has created quite a serious environmental problem. Edible film is an alternative packaging that can decompose naturally, one of the materials that can be used to make edible films is starch. This study aims to determine the composition of corn cob starch and plasticizers that can produce edible films with the best properties. The starch used is derived from corn cobs and the plasticizers used are glycerol and sorbitol. The edible film in this study was made by the casting method by dispersing the raw materials, heating the mixture, printing the edible film and drying the edible film. This research was conducted with variations in the corncob of 5, 6 and 7 in grams and the variation of the ratio of glycerol to sorbitol plasticizer is 2:8; 3:7; 5:5; 7:3; 8:2 (ml). The more starch content increases the thickness of the edible film and tensile strength, but the elongation and water vapor permeability decreases, the best edible film is obtained at the glycerol-sorbitol composition ratio of 5:5 with the amount of corncob starch of 7 grams.
Key words: Corn cobs / Edible film / optimization / Surface response method
