This study aims to determine the physicochemical and mechanical characteristics of edible films based on a combination of Na-CMC, cassava starch, and chitosan with the addition of glycerol plasticizer. This study uses the Factorial Complete Random Design (RAL) method with two treatment factors, namely a combination of polymers (A1: Na-CMC+Chitosan, A2: Na-CMC+Starch, A3: Starch+Chitosan, A4: Na-CMC+Starch+Chitosan) and glycerol concentration (B1: 2 ml, B2: 3 ml, B3: 4 ml) with three repeats and follow-up tests of real difference (BNJ) and determination of the best treatment using the effectiveness index method (De Garmo). The results showed that the combination of polymers had a significant effect on water absorption, tensile strength, elasticity, brittleness, moisture content, water vapor permeability (WVP), and edible film pH. The concentration of glycerol had a significant effect on water absorption, elasticity, brittleness, moisture content, and WVP, but had no significant effect on tensile strength. The interaction of the two treatments had a significant effect on all the parameters tested. The best edible film based on the De Garmo method was the A1B3 treatment (a combination of Na-CMC-Chitosan with glycerol 4 ml). The resulting characteristics are tensile strength value of 0.0200 MPa, elasticity of 91.33%, brittleness 62.87 N, water absorption 69.50%, moisture content 38.15%, water vapor permeability of 2.57E-10 g·m⁻¹·s⁻¹· Pa⁻¹, and pH value of 7.00 (neutral). Although the tensile strength value does not meet the JIS Z 1707 standard, the A1B3 formulation shows the most optimal barrier performance and physicochemical stability as an alternative to biodegradable packaging.
