Abstract

Bekatul padi mengandung pati yang dapat dimanfaatkan sebagai bahan pembuatan plastik biodegradable. Penelitian ini bertujuan untuk mengetahui pengaruh jenis plasticizer terhadap karakteristik plastik biodegradable berdasarkan uji swelling, uji kuat tarik, uji degradasi dan uji morfologi. Plastik biodegradable dibuat dengan melarutkan bekatul dalam aquades dan ditambahkan asam asetat, selanjutnya larutan dipanaskan pada suhu 65?C selama 15 menit. Setelah itu, menambahkan plasticizer dan larutan kitosan kemudian diaduk selama 60 menit pada suhu 65-70?C. Larutan dicetak kemudian didiamkan dalam suhu ruang hingga kering kemudian dilakukan analisa pada plastik biodegradable. Variabel yang digunakan yaitu : jenis plasticizer (gliserol, sorbitol, propilen glikol). Hasil penelitian menunjukkan jenis plasticizer yang berbeda memberikan pengaruh yang berbeda pada karakteristik plastik biodegradable dengan hasil terbaik yaitu pada plasticizer sorbitol dengan uji kuat tarik 64,27 MPa, elongasi 3,33%, swelling 30,77% dan degradasi 63,64%. Analisa morfologi menunjukkan plastik biodegradable memiliki permukaan yang kurang rata dan berongga

Abstract

Research on the manufacture of bioplastics from bran is one of the efforts todevelop the development of environmentally friendly plastics because they can bedecomposed by microorganisms. In addition, this study also seeks to reduceenvironmental pollution due to the disposal of rice mill waste. The research wasconducted by mixing rice bran with water, sulfuric acid and sorbitol in variousvariations of the ratio of sorbitol and bran 1:10; 2:10; 3:10; 4:10 and 5:10 (v:b).Furthermore, chitosan was added as a reinforcement with variations in theaddition of chitosan with bran, namely 4:10; 6:10; 8:10; 10:10 and 12:10 thenprinted and analyzed for dance strength, swelling and surface morphology. Thetest results showed the highest tensile strength value in the ratio of sorbitol andbran 5:10 and chitosan bran 10:10 with the highest tensile strength value of 64.27MPa and 25% swelling value. Surface morphology shows an uneven and hollowsurface.
