摘要：Bioplastic material development by utilizing indigenous commodity is a trend to overcome the environmentdamage by plastic and as a sustainable resource. As a home of broad biodiversity, Indonesia has morespecies of Amorphophallus that are still unexplored. One of species among them that is possible toexplore as bioplastic material is Walur. The aim of this work is to study the behaviour of bioplastics withthe Walur corm as a raw material and glycerol as a plasticizer. Glycerol portion is varied in 7 levels andin a range of 6% to 30%. The result showed that glycerol has significantly affected the tensilestrength, elongation and modulus elasticity of the Walur plastics. Glycerol could decrease both,elongation and elasticity of Walur plastic despite increasing effect on elongation behaviour.
