This shows that edible film has the potential to be a food packaging material, especially for oyster mushrooms, by utilizing materials available in nature [5].
However, the Hawthorn plant is a medicinal plant that is rarely found in Indonesia [6], so other alternative materials are needed that can be used as basic ingredients for making edible films.
