- Edible film is an environmentally friendly alternative packaging material because it uses renewable materials such as banana hump starch. Banana cuffs have weakness that produces a surface that is not elastic so it takes additional material to repair the surface. The addition of Caragenan can increase the elasticity level in edible films based on banana hump so as to produce a surface structure that corresponds to the edible standard film. This research aims to determine the influence of the addition of Caragenan and glycerol concentration on the physical and mechanical characteristics of the resulting film. The study was a randomized group design (RAK). The first factor is glycerol with a concentration of 0.75%, 1.25%, 1.75% and the second factor is the addition of Caragenan with concentrations of 1%, 1.5% and 2%. The tested parameters are thickness, transparency, strong tensile, elongation, solubility, moisture transmission rate, and surface structure. The results showed that the addition of caragenan and glycerol concentrations with different concentrations of real effect on thickness, transparency, strong tensile, elongation, solubility and the transmission rate of moisture from edible films were produced. The best edible film quality is produced in the K3G1 treatment (carrageenan concentration of 2% and glycerol 0.75%) With a thickness of 0.113 mm; 2.95 A546/mm transparency; Strong tensile 23.281 MPa; Elongation 19.14%; Solubility in water 81%; and moisture transmission rate of 2.69 g/m2/24h. Edible films are produced to meet the standard based on JIS Z 1707:1997.
