Abstract
The existence of waste is an important problem in everyday life. One type of waste that currently widely found throughout Indonesia is the albedo of jackfruit. The albedo of jackfruit contains 38.69% cellulose and 15.87% carbohydrates, so it’s a great opportunity to be used for making edible films. This study aims to determine the properties and effects of adding glycerol volume to edible films made from jackfruit albedo. The research method in this study was a randomized block design (RBD) with factors, namely the starch albedo of jackfruit and glycerol. The observed variables included thickness, tensile strength, elongation, water resistance, morphology, functional groups, and biodegradability. The best results were obtained by adding 4 grams of starch and 3 ml of glycerol with thickness 0.15 mm, tensile strength 0.2292 Mpa, elongation 40.74%, and water absorption 21.6362%. Edible films can be completely degraded using EM4 on the 15th day. The functional group of the resulting edible film has hydrogen bonds between starch-glycerol-chitosan with the shape of the edible film surface having indentations and bubbles. The addition of starch and glycerol causes the thickness increase while the water resistance decreases, but the addition starch cause tensile strength increases and elongation decreases.
