Edible coating is one form of packaging technology with environmentally friendly theme. The raw materials of edible coating derived from nature, while the waste is decomposed or even zero waste. The research of edible coating using experimental design RAL (completely randomized design) with two factors, namely the type of raw material used tuber starch (cassava, arrowroot and canna) and the percentage of starch (3%, 4% and 5%) (b/v) with three replications time. The quality analisys of edible coating includes the physical properties (thickness (mm), tensile strength (N) and elongation (mm)) and chemical properties (moisture content (%), solubility (%), the water vapor transmissin rate (g/hour) and peroxide (mek/kg). The research showed that the edible coating with sorbitol plasticizer of arrowroot starch 4% provide best physicochemical properties (thickness 0,09mm; 1,63N tensile strength; elongation 84,38mm; water content of 11.19%; solubility of 31.40%; the transfer of water vapor 0,16g / h and 3,20mek/ kg).
