Biofoam is foam derived from starch so that it can be degraded and does not interfere with the environment. Cassava has the largest starch content among tubers, but the level of consumption of household people tends to make cassava a potential source of starch that is used in other forms such as biofoam. This study aims to determine the effect of the vary content of bacterial cellulose on cassava starch-based biocomposite foam. This research varied the content of bacterial cellulose to cassava starch, ie 0.0%, 0.5%, 1.0%, 1.5%, and 2.0% weight, then produce and tested its mechanical properties and surface morphology with the Scanning Electron Microscope. The results of this study are the highest tensile strength produced by biocomposite foam with the addition of 1% bacterial cellulose with an increase of 690.8 kPa and the most homogeneous cavity area produced by biocomposite foam with the addition of 1% bacterial cellulose.
