Abstract
Penelitian tentang pembuatan dan karakterisasi film
pati kulit ari singkong/kitosan dengan plasticizer asam oleat telah
dilakukan. Pada penelitian ini, pati kulit ari singkong bertindak
sebagai matriks, kitosan sebagai biopolimer pencampur dan asam
oleat sebagai lipida. Formulasi larutan yang digunakan diberi
nama sebagai berikut: CS75 OA 0%, CS60/CH15/OA 0%,
CS45/CH30/OA 0%, CS37,5/CH37,5/OA 0%, CH75/OA 0%, CS75/OA
1%, CS60/CH15/OA 1%, CS45/CH30/OA 1%, CS37,5/CH37,5/OA 1%,
dan CH75/OA 1%. CS merupakan pati kulit ari singkong, CH
merupakan kitosan dan OA merupakan asam oleat. Asam oleat
ditambahkan hingga mencapai konsentrasi akhir larutan FFD
sebesar 0% dan 1% (v/b). Film yang dibuat dikarakterisasi
dengan Fourier Transform Infra Red (FTIR), Tensile Strenght
dan analisa water uptake. Adapun hasil yang diperoleh dari
penelitian ini adalah bahwa film kulit ari singkong/kitosan dengan
plasticizer asam oleat memiliki penampakan visual transparan
dan homogen. Hal ini mengindikasikan bahwa pati kulit ari
singkong, kitosan dan asam oleat mampu berinteraksi dengan
baik. Penambahan asam oleat hingga mencapai konsentrasi akhir
larutan 1% (v/b) mempengaruhi sifat fisik film, yaitu
meningkatkan % elongasi, namun menurunkan nilai stress, nilai
Modulus Young dan nilai water uptake secara signifikan.

The preparation and characterization of epidermis
cassava starch/chitosan has been conducted using oleic acid
plasticizer. In this study, epidermis cassava starch acts as a
matrix, chitosan as a mixing biopolymer and oleic acid as lipids.
Solution formulations used were as follows: CS75 OA 0%,
CS60/CH15/OA 0%, CS45/CH30/OA 0%, CS37,5/CH37,5/OA 0%,
CH75/OA 0%, CS75/OA 1%, CS60/CH15/OA 1%, CS45/CH30/OA
1%, CS37,5/CH37,5/OA 1%, and CH75/OA 1% where CS was the
epidermis cassava strach, CH was chitosan and OA was oleic
acid. The oleic acid was put to the final concentration of FFD
solution at 0% and 1% (v/b). Fourier Transform Infra Red
(FTIR), Tensile Strenght dan analysis of water uptake were used
to characterized the film formed. The results showed that the
epidermis cassava starch/chitosan’s film with oleic acid
plasticizer has transparent and homogeneous visual appearance
indicating that all the three compound was able to interact well.
The addition of oleic acid solution until at final concentration of
1% (w/v) influenced the physical properties of the film by
increasing the % elongation but lowers the stress, the modulus
Young and water uptake significantly.
