Abstract
This research was conducted to determine the characteristics of bioplastics with the addition of beeswax and glucomannan. This research was carried out at the Animal Products Technology Laboratory, Faculty of Animal Husbandry, Brawijaya University, with the material used being bioplastic made from gelatin with the addition of beeswax (obtained from farms in Malang Regency) and glucomannan. This research used an experimental method with a completely randomized design and 4 treatments adding 0.25%, 0.5%, and 0.75% beeswax to bioplastics with 3 replications. The characteristics of bioplastics with the addition of beeswax and glucomannan will be reviewed based on the variables of thickness, water resistance, water vapor permeability, biodegradability, tensile strength, and elongation. The results showed that the addition of beeswax and glucomannan had no significant effect (p > 0.05) on thickness, water vapor permeability, biodegradability, tensile strength, and elongation. However, the addition of beeswax and glucomannan had a significant effect (p > 0.05) on water resistance. The addition of beeswax and glucomannan also increased (p <0.05) the results of water resistance and tensile strength while reducing (p <0.05) the results of thickness, water vapor permeability, biodegradability, and bioplastic elongation. It can be concluded that beeswax and glucomannan are able to provide strong bioplastic characteristics and have the property of protecting the product from damage.
