The condition for making optimum conditions for making biodegradable film from <em>E. cottonii</em> with treatment of glycerol concentration (0; 0,25; 0,5; 0,75; and 1%), tapioca concentration (2; 4; 6; 8; and 10%) , carboxy methyl cellulose (CMC) concentration (1; 2; 3; 4and 5%) and chitosan concentration (1; 2; 3; 4; and 5 The experimental design uses a surface response method with 4 replications. The analysis carried out consisted of elongation percent, tensile strength, solubility and biodegradable film using surface response method. The optimum value occurs in the process conditions using a concentration of glycerol of 0.162%, tapioca concentration of 3.78%, CMC concentration of 2.5% and chitosan concentration of 1.62% with tensile strength 95.013 Mpa, percent elongation of 8.92%, and solubility 80.62%.<br /><br /></p&gt;}, number={2}, journal={Jurnal Pengolahan Hasil Perikanan Indonesia}, author={Hidayati, Sri and Zulferiyenni, Zulferiyenni and Satyajaya, Wisnu}, year={2019}, month={Aug.}, pages={340-354} }
