    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. Preparation 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%.
     
    Upaya untuk menanggulangi masalah lingkungan terhadap bahan plastik yang sulit terdegradasi telah banyak dilakukan. Salah satunya dengan menggunakan bakteri Effective Microorganism 4 (EM4). Pembuatan plastik polipropilen/kitosan (PP/kitosan) dengan plastisiser gliserol dan poligliserol asetat (PGA) telah dilakukan dengan menggunakan metode refluks. Analisa sifat morfologi plastik dilakukan dengan uji Scanning Electron Microscopy (SEM) dan analisa sifat biodegradasi dilakukan dengan metode mixed microbial batch. Analisa morfologi permukaan plastik PP/kitosan, PP/kitosan-gliserol, dan PP/kitosan-PGA menunjukkan permukaan yang homogen. Uji biodegradasi dengan menggunakan bakteri EM4 menghasilkan persen degradasi optimum sebesar 71,18% yang diperolehi dari plastik PP/kitosan dengan pengisi kitosan sebesar 20% dan plastisiser PGA 2,5%.
