Jember potential to become one of the world's coffee suppliers. The survey showed that farmers need to add the sorting stage in the processing of coffee to get good quality coffee beans and uniforms. Stages of the process that needs to be improved is the stage of drying and storage. At the stage of drying, need to improve standards of drying up to 12.5% (SNI) as a standard in use today are still high enough to 14%. Water content is still possible to increase especially during storage and hence, potentially causing the growth of Aspergillus ochraceus as a ocratoxin producer. At the storage stage, the coffee must be placed in clean bags and stacked on a wooden base, and does not stick to the wall. This is done to avoid increasing the water content in the coffee because of moisture on the floor and walls. From the analysis of water content is known that an increase in product moisture content of 13.6% to 13.9% during storage.

Biodegradable foam is a type of environmentally friendly packaging made from biopolymers in the form of starch that can be degraded naturally. This study aims to determine the characteristics of biodegradable foam and its prototype made from cassava starch as a biopolymer substitute for synthetic polymers by adding variations of bagasse flour to compact the structure and polyvinyl alcohol (PVA) which functions to reduce water absorption. The stages of making biodegradable foam are started by making bagasse flour, making biodegradable foam sheets using the baking process, and making a prototype bowl of biodegradable foam. The making of this biodegradable foam consists of 6 formulas by adding variations of bagasse flour (5%, 10%, 15%) and PVA (20%, 40%) from 36 grams of starch mass. The tests carried out were in the form of water absorption, biodegradation, thickness, tensile strength, and density tests. The best treatment was found in the A3B1 formula which was used as the basis for making a prototype bowl of biodegradable foam. The addition of variations of bagasse flour and PVA had a significant effect on the characteristics of water absorption and biodegradation, while the other characteristics were only PVA which had a significant effect. The results of the best treatment as the basis for making a prototype bowl of biodegradable foam with water absorption characteristics of 25.93% and biodegradation of 45.95%.
