Biodegradable film dikembangkan sebagai alternatif pengemas plastik. Biodegradable film dapat dibuat dari pati garut, pati ubi jalar, dan hydroxypropyl methylcellulose (HPMC). Biodegradable film berbasis polisakarida memiliki kelemahan yaitu mudah rapuh sehingga perlu ditambahkan plasticizer untuk meningkatkan fleksibilitas film. Tujuan penelitian ini yaitu mengetahui pengaruh jenis bahan, jenis plasticizer, dan konsentrasi plasticizer, serta interaksi faktor jenis bahan, jenis plasticizer, dan konsentrasi plasticizer terhadap karakteristik kimia, fisik, dan sensoris biodegradable film. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL). Faktor yang diteliti meliputi jenis bahan (pati; pati ubi jalar; hydroxypropyl methylcellulose), jenis plasticizer (gliserol dan sorbitol), dan konsentrasi plasticizer (4%; 6%; 8%). Variabel yang diamati terdiri dari variabel kimia (kadar air dan kadar abu), fisik (ketebalan dan kelarutan), dan sensoris (kejernihan, warna, aroma, tekstur, dan kesukaan). Hasil penelitian menunjukkan bahwa (1) Film pati ubi jalar dan pati garut memiliki kadar abu, ketebalan, dan kelarutan lebih rendah dibandingkan HPMC. (2) Plasticizer sorbitol menghasilkan film dengan kadar air lebih rendah dibandingkan plasticizer gliserol. (3) Pada konsentrasi 4-8%, semakin tinggi konsentrasi plasticizer, maka kelarutan akan meningkat. (4) Interaksi antara jenis bahan, jenis plasticizer, dan konsentrasi plasticizer tidak memberikan perbedaan terhadap karakteristik kimia, fisik, dan sensori biodegradable film yang dihasilkan.

Arrowroot starch, sweet potato starch, and hydroxypropyl methylcellulose are potential to be developed as the biodegradable film as an alternative to plastic packaging. The polysaccharide-based film produces a brittle biodegradable film. Therefore, it needs plasticizer to increase the flexibility of the film. The research was to study the effect of material type, plasticizer type, plasticizer concentration, and the interaction between three factors on the chemical, physical, and sensory characteristic of the film. The research used Completely Randomized Design Factorial. The factor of treatments were material type (arrowroot starch; sweet potato starch; hydroxypropyl methylcellulose), plasticizer type (glycerol; sorbitol), and plasticizer concentration (4%;6%;8%). The observation consists of a chemical variable (moisture content and ash content), physical variable (thickness and solubility), and sensory variable (clarity; color; aroma, texture; and preference). The result shows that (1) sweet potato and arrowroot starch film indicates a lower value of ash content, thickness, and solubility than  HPMC. (2) Sorbitol indicates a lower value of moisture content. (3) At 4-8% concentration, the higher level of plasticizer concentration indicates a higher of solubility. (4) The interaction between the factors didn’t show any difference on chemical, physical, and sensory characteristic of the biodegradable film.
