Use of biopolybag from tapioca starch and sawdust waste

Abstract

One alternative to overcome the weakness of polybags, namely creating plastic waste, is the use of biodegradable polybags (biopolybags) that are easily degraded so that they can be planted directly without having to be opened and disposed of. Therefore, the purpose of this study was to determine the effect of comparison between tapioca starch and sawdust pulp on mechanical properties, plant height and diameter growth, and soil chemical properties. The analysis used in this research is a tensile test using ASTM D638 2005 standard, elongation (elongation at break), elasticity (young's modulus), and water absorption using SNI. The comparison of tapioca starch and sawdust pulp had a significant effect on the mechanical properties of the tensile strength and elongation tests, and had no significant effect on the elasticity.
