| Summary: | Currently, the material used in making commercial styrofoam is polystyrene. Styrofoam is commonly utilized in food packaging applications because of its low density properties. However, styrofoam has the disadvantage of breaking down for a very long time. This study aims to make starch foam from starch as a natural material that is environmentally-friendly as a substitute for styrofoam and also has an admirable decomposition time. Starch is a polysaccharide that is abundant in nature. Starch is commonly found in stems, roots, tubers, and fruit.
The starch used in this study was tapioca starch. Starch foam was made by using the microwave treatment method until the starch has gelatinized and undergoes solidification. To increase the plasticity of starch foam, it was necessary to add glycerol plasticizer as an additives. Variation in glycerol composition was carried out to determine its relation to density, blowability, foam cell size, and decomposition properties. In this study, the results showed that Specimen SG15 had the lowest density which was 0.313 g/cm3, blowability was up to 73.46%, the largest foam cell size was obtained on Specimen SG20 which was 0.524 mm2, and Specimen SG20 had the fastest 7-day decomposition properties which was 46.433% when glycerol was added.
