Starch is one of the basic ingredients for making edible films (edible coatings), but it tears easily, so it needs the addition of plasticizers. This study aims to make edible film from durian seed starch (Durio zibethinus Murr) with the addition of plasticizers, glycerol and sorbitol and determine its characterization. The results showed that the best edible film was produced by adding 2.5% (w / v) of glycerol and 2% (w / v) of sorbitol. The physical characteristics of the edible film are respectively: thickness 0.1700 mm and 0.1633 mm, tensile strength 0.008 Kgf / mm2 and 0.010 Kgf / mm2, percent elongation 42.76% and 37.13%, elasticity 0.0202 and 0.0272. The chemical characteristics of edible film include: water absorption test of 58.22% and 60.43%, solubility of 40.89% and 26.42%, water vapor transmission rates of 0.2275 g / jamm2 and 0.3127 g / jamm2, and pH 6.90 and 7.85. The results of functional group analysis (FTIR) show that the process of making edible films in this study is a physical mixing process. The shelf life of edible films at room temperature is 5 days and at cold temperature for 7 days. The biodegradability test showed that the edible film in this study could be completely degraded within 7 days. This shows that the durian seed starch edible film is an environmentally friendly packaging.
