Pembuatan Edible Film Dari Pati Ubi Banggai (Dioscorea Cf Alat) Dengan Penambahan Polivinil Alkohol (PVA)

Telah dilakukan penelitian pemanfaatan ubi banggai sebagai sumber bahan baku
pembuatan edible film dengan penambahan PVA. Tujuan penelitian ini adalah
untuk mengetahui pengaruh konsentrasi pati ubi banggai dan PVA terhadap kuat
tarik edible film dan berapa lama waktu edible film terurai. Hasil yang diperoleh
diuji kuat tarik dan lama waktu degradasi edible film.Hasil penelitian menunjukkan
edible film menghasilkan nilai kuat tarik 2,25 sampai 4,31 MPa dan memiliki rentang waktu degradasi 1-4 hari dan ramah lingkungan.

Research has been carried out on the utilization of Yam Banggai as a source of raw
material for making edible films with the addition of PVA. The purpose of this
study was to determine the effect of the concentration of sweet potato starch and
PVA on the tensile strength of the edible film and how long it took for the edible
film to decompose. The results obtained were tested for tensile strength and the
length of time for edible film degradation. The results showed that edible film
produced a tensile strength value of 2.25 to 4.31 MPa and had a degradation time
range of 1-4 days and was environmentally friendly.
