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.
