Abstrak

Komposit dari polylactic acid (PLA) dan mono ester plasticizer (MEP) dari tepung kayu dan bekatul disiapkan untuk mengevaluasi pengaruh jenis bahan isian MEP terhadap sifat mekanis, fungsi, sifat termal, dan morfologis komposit tersebut beserta reaksi degradasinya. Hasil analisis dengan SEM menunjukkan bahwa terdapat interfacial adhesion yang cukup besar antara matriks PLA dan MEP dari tepung kayu dan bekatul, yang dapat disebabkan oleh mechanical interlocking antara keduanya. Penambahan 10 dan 30% MEP tepung kayu dan bekatul menyebabkan perbaikan regangan (strain) dan tegangan tarik (tensile). Komposit PLA dan MEP dari tepung kayu dan bekatul mengalami degradasi dengan hidrolisis pada bagian yang berstruktur kristal.
