Abstract
Concentration of base materials and plasticizers used in the formulation of edible film was believed to affect physical characteristics of the film. The objectives of this study were to evaluate the effects of base material (carrageenan) and plasticiser (glycerol) concentrations on the characteristics of edible films produced and to determine the best concentrations of these two components based on the physical characteristics of the films. The experiment was conducted using a completely randomized factorial design with triplicated. The treatments applied were the concentrations of carrageenan (1%, 2%, and 3% (w/v)) and glycerol (5%, 10%, and 15% (w/w)). The results showed that carrageenan and glycerol concentrations used in the formulation of edible film affect the edible film characteristics. Film thickness and moisture content were significantly influenced by carrageenan and glycerol concentrations, while film elongation was only affected by carrageenan concentration. The best physical characteristic of the edible films was obtained when carrageenan and glycerol concentrations were 3% and 10% respectively.

Karakterisasi edible film karagenan dengan pemlastis gliserol. Konsentrasi bahan dasar dan pemlastis yang digunakan dalam formulasi Edible film diyakini mempengaruhi karakteristik fisik film. Tujuan dari penelitian ini adalah untuk mengevaluasi pengaruh konsentrasi bahan dasar (karagenan) dan pemlastis (gliserol) terhadap karakteristik Edible film yang dihasilkan dan untuk menentukan konsentrasi karagenan dan gliserol yang terbaik berdasarkan karakteristik fisik dari Edible film. Perlakuan yang diterapkan meliputi konsentrasi karagenan (1%, 2%, and 3% (b/v)) dan konsentrasi gliserol (5%, 10%, dan 15% (b/b)). Hasil penelitian menunjukkan bahwa konsentrasi karagenan dan gliserol yang digunakan dalam formulasi berpengaruh terhadap karakteristik Edible film. Ketebalan film dan kadar air sangat dipengaruhi oleh konsentrasi karagenan dan gliserol, sedangkan pemanjangan hanya dipengaruhi oleh konsentrasi karagenan. Karakteristik fisik Edible film yang terbaik diperoleh pada konsentrasi karagenan 3% dan konsentrasi gliserol 10%
