description: There are tons of plastic waste in Indonesia, which includes food packaging. Plastic packaging who distributed in public is synthetic which has ability to decompose poorly, so this has bad impact for environment. This adverse impact has led various efforts to reduce its use, one of them is through development of biodegradable packaging. Biodegradable film is type of package that easily decomposed by microorganisms. Biodegradable film with starch based generally have low physical and mechanical characteristics, so it needed to add filler such as cellulose from Gracilaria sp. The aim of this research was to determine effect of addition of cellulose Gracilaria sp. on physical and mechanical characteristics, to determine cellulose concentration of Gracilaria sp. selected to produce the best biodegradable film, and to determine the biodegradation ability of biodegradable film with cellulose concentration. The research used Completely Randomized Design (CRD) one factor which consisted of five levels of Gracilaria sp. concentration, that is 0%, 1%, 3%, 5%, and 10%. Results showed the average value of each parameter biodegradable film, such as thickness 0,029 – 0,082 mm, tensile strength 18,8– 25,82 MPa, elongation 1,54 – 5,7%, lightness (L*) 84,15 – 84,7, a* -0,05 – -0,3, b* 4,8 – 5,8, density 1,78 – 2,40 g/cm3 , WVTR 7,18 – 14,61 g/(m2 h), WHC 7,36 – 10,54 g/g, and OHC 8,32 – 9,4 g/g, on the 7th day, samples became brittle and almost degradated perfectly. The addition of Gracilaria sp. cellulose significantly affected all parameters except L*. The treatment that produces best biodegradable film is the variation of 10% Gracilaria sp. cellulose concentration.
