Karakteristik Edible film Dari Rumput Laut Merah (Eucheuma cottonii) Dengan Konsentrasi Karagenan Berbeda

---

Edible film is a primary packaging in the form of a thin layer and serves as a food coating that can be made from hydrocolloid compounds. Carrageenan polysaccharide is one of the hydrocolloids used to make edible films because it produces strong gel properties. Eucheuma cottonii is a relatively high producer of kappa carrageenan which is about 50%. This study aimed to determine the physicochemical characteristics of carrageenan and edible film characteristics. The research method was conducted experimentally with an experimental design, namely a non-factorial Completely Randomized Design (CRD) with 3 treatment levels, namely carrageenan concentration of 0.5 g (K1); 1 g (K2); 1.5 g (K3). The parameters of this study were CAW (Clean Anhydrous Weed) value and impurities value, physico-chemical testing of carrageenan (yield, gel strength, viscosity, moisture content and ash content) and physical and mechanical analysis of edible film (testing tensile strength, thickness, percent elongation and water vapor transmission rate). The results showed a CAW value of 65.4% and an imputities value of 0.66%. The yield was 45% with a viscosity of 1833 cP, gel strength of 29.96 g/cm, moisture content of 9.70%, and ash content of 34.47%. The results of physical and mechanical analysis of edible film showed the value of tensile strength K1 5.37 MPa, K2 9.49 MPa, K3 10.58 MPa, thickness K1 0.07mm, K2 0.03mm, K3 0.06mm, water vapor transmission rate K1 15.80 g/m /day, K2 30.13 g/m /day, K3 27 .69 g/m /day, and percent elongation K1 5.37%, K2 9.86%, K3 13 .85%. From the results of the study, the best results were obtained in the K3 treatment, namely theconcentration of carrageenan 1.5g.
