    Abstract
    Plastik Biodegradable Pati Porang dan Kitosan dengan Plasticizer Gliseroldibuat dengan proses pemanasan pada suhu 80-85oC dan pengeringan pada suhu 60oC. Hasil terbaik plastik biodegradable diperoleh pada konsentrasi pati porang 40 % , kitosan 60% dengan konsentrasi gliserol 80% dan memiliki nilai kuat tarik 20,8902 Mpa, nilai ketebalan 0,384 mm, nilai elongation 9,7226%, dan nilai kemampuan terdegradasi 85,7 % . Hasil spektrum FT-IR menunjukkan tidak adanya perubahann bilangan gelombang dari spektrum pati porang, kitosan dan gliserol dengan gugus fungsi O-H, C-O, dan N-H. Hal ini menunjukkan bahwa plastikyang dihasilkan hanya berinteraksi secara fisik. Analisis SEM terlihat adanya titik-titik putih dan lekukan pada permukaan plastik biodegradablehal ini menandakan bahwa pati porang padaplastikbiodegradable belum terlarut sempurna sehingga plastic biodegradable pati porang memiliki permukaan yang tidak merata.
     
    The Biodegradable Plastic From porang's strach and chitosan with gliserol plasticizer is made by heating at a temperature of 80-85⁰C and drying at a temperature of 60⁰C. The best results of bioplastic films were obtained at a concentration of 40% porang's starch, 60% chitosan with 80% gliserol volume concentration have value of tensile strength 20,8902 Mpa, value of thickness 0,384 mm, value of elongation 9,7226 %, and value of biodegradability 85,7%. The FT-IR spectrum results showed that nothing change in the wave number of the porang strach, chitosan and sorbitol spectra with the O-H, C-O, and N-H functional groups. This is showing that the result of the plastic is only physically interacted. SEM analysis shows that there are white dots and grooves on the surface of the biodegradable plastic, this indicated that the porang's starch in the bidegradable plastic has not been completely dissolved so that the porang's starch of biodegradable plastic has an unsmooth surface.
