Abstract

Biodegradable foam (biofoam) is a type of bioplastic to be used as an alternative packaging to replace styrofoam that is safe and environmentally friendly. This study aims to determine the effect of adding chitosan on the characteristics of biofoam made from cassava peel starch (A) and banana peel starch (B). In the manufacture of biofoam, various A/B ratios used are 1:0; 3:2; 1:1 (w/w). While the chitosan content added was 0%, 15%, and 30% by weight of starch, as well as NaHCO3 blowing agent with a content of 12% by weight of starch. The production of biofoam was carried out using the thermopressing method with a printing temperature of 125°C, and a printing time of 7 minutes. The results of biofoam were characterized based on density, water absorption, compressive strength, biodegradation, and FTIR functional groups. Based on the research results, it is known that biofoam is close to commercial biofoam standards, namely biofoam with an A:B ratio of 3:2, and the addition of 15% chitosan with a water absorption capacity of 33.68%, a compressive strength value of 5.05 MPa, and a decomposition power of 17.44%. This variation has the functional groups N–H, O–H, C–H, C=O, C–N, and C–O. Keywords: banana peel starch, biofoam, cassava peel starch, chitosan, thermopressing
