REVIEW: PENGARUH KONSENTRASI LARUTAN KITOSAN SEBAGAI COATING AGENT TERHADAP DAYA SERAP AIR PADA BIOPLASTIK DARI PATI SINGKONG DAN GLUTEN

Muhammad Yusuf Ramadhani, Sigit Hadiantoro

Abstract


Bioplastik merupakan jenis plastik dibuat dengan bahan berasal dari tanaman. Plastik ini dapat diuraikan oleh mikroorganisme atau jamur secara alami. Bioplastik dapat tersusun dari pati, lignin, selulosa, atau dari hasil samping perkembangbiakan mikroorganisme. Bioplastik memiliki kelemahan dalam hal ketahanan air daya tahan penyerapan air dan sifat mekanik. Kelemahan tersebut dapat diatasi dengan menambahkan kitosan sebagai bahan tambahan dari penyerapan air dan gluten untuk memperbaiki sifat mekanik bioplastik. Studi penelitian ini digunakan sebagai mendapatkan cara jenis bioplastik baru dengan pendekatan secara teori pada penelitian pembuatan bioplastik sebelumnya. Studi dilakukan pada penelitian bahan bioplastik dari pati singkong, gluten, dan kitosan. Karateristik bioplastik meliputi tensile strenght dan water uptake. Hasil studi didapatkan karakteristik bioplastik gluten memiliki water uptake yang lebih rendah dengan nilai 38-65%. Karakteristik kuat tarik memiliki nilai yang tinggi pada bioplastik pati kentang-kitosan sebesar 53 MPa sedangkan bioplastik pati singkong dengan coating kitosan layer by layer didapatkan kuat tarik sebesar 14,47 ± 1,25 MPa.
