Abstract

Biocomposites from yam bean starch with yam bean bagasse (YBB) fibers as reinforcement has been successfully fabricated. The fabrication method was solution casting. YBB was variated for 1, 2, 3 and 4wt% (from dry weight starch basis). 2 mL glycerol was used as a plasticizer. The relative humidity (RH) condition in moisture testing was 99%. The result shows that the addition YBB able to decreased moisture absorption of starch film. The lowest moisture absorption was in biocomposites with 4wt% YBB. The moisture absorption test was supported byfourier transform infrared (FTIR) data.
