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…
