Abstract

Biodegradable Foam (Biofoam) material has been made for application of styrofoam substitute food packaging material from a mixture of starch with chitosan as an additive. The purpose of this study was to determine the effect of molding temperature on biofoam products and to determine the effect of chitosan addition on the physical, mechanical, and biodegrability properties of biofoam made from cassava peel starch (a) and banana peel starch (b) which is close to commercial biofoam standards. The production of biofoam uses variations in molding temperature of 125, 150 and 175 °C and variations in chitosan weight with variations of 0, 1, 2 and 3 grams. The resulting biofoam product was then tested for density, water absorption, compressive strength, biodegradation and functional groups with Fourier Transform Infrared  (FTIR). Based on the results of the study, it is known that biofoam that is close to commercial standards is found in the addition of 3 gr chitosan weight with a molding temperature of 125 °C with a density value of 0.423gr/cm3, water absorption of 42.54% and compressive strength of 0.0045 Mpa. As for biodegradation, biofoam products will decompose 55.17% for 55 days in 0 g chitosan weight with a thermopressing temperature of 175 °C. The spectrum results obtained on biofoam have C-H, C-O, C-N, N-H, C=O and O-H functional groups.

Abstract

Biodegradable foam(biofoam) is a type of bioplastic that is used as an alternative packaging to replace styrofoam which is safe and environmentally friendly. This study aims to determine the characteristics of biofoam made from cassava peel starch (A) and banana peel starch (B), as well as the effect of adding chitosan to the physical, mechanical, and biodegradation properties of the resulting biofoam. In the manufacture of biofoam, the variation of the A:B ratio used is 1:0; 3:2; 1:1 (%w/w). While the chitosan content added was 0%, 15%, and 30% by weight of starch and blowing agent NaHCO3 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 125C and a printing time of 7 minutes. The results of biofoam were characterized by 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 density value of 0.560 g/cm3, the water absorption capacity of 33.68%, compressive strength value of 5, 05 MPa, and the decomposition power of 17.44%. These variations have functional groups NH, OH, CH, C=O, CN, and CO.
