Abstract:
Attempts to tackle environmental problems against hard-to-degrade plastic materials have been widely practiced. One of them was by using Effective Microorganism 4 (EM4) bacteria. Preparations of polypropylene / chitosan (PP / chitosan) plastic with glycerol plastisiser and polyglycerol acetate (PGA) have been done by using reflux method. Plastic morphology analysis was done by Scanning Electron Microscopy (SEM) test and biodegradation characteristic was analyzed by mixed microbial batch method. Analysis of surface plastic morphology of PP / chitosan, PP / chitosan-glycerol, and PP / chitosan-PGA showed a homogeneous surface. Biodegradation test was using EM4 bacteria resulted in an optimum percentage of degradation of 71.18% obtained from PP / chitosan plastic with 20% chitosan filler and PGA plastisiser 2.5%.
