Abstract

Cellulose from the solid waste of seaweed Eucheuma cottonii is one of the wastes that can be used as raw material for making biodegradable films. The condition for making optimum conditions for making biodegradable film from E. cottonii 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%.

Abstract

Free fatty acid and microbial activity of weaning food from bread fruit (Atocarpus communis) and surly bean (Mucuna pruriens L) during storage was evaluated in this research. Variables of research were consisted of duration of storage on 2, 4, 6 and 8 weeks and also the using of polyetylene and alumunium foil. The result showed that product has fulfilled the SNI standard with level of : protein 15.42%, fat 6.74%, fiber 3.375%, water 3.63%, ash content 3.576% and carbohydrate 72.25. During storage, free fatty acid (FFA) level and microba  increased and had significant effects between two kinds of packaging material where alumunium foil tended to have a better effect than that of polyetylene. Keywords : weaning food, bread fruit, slury bean, storage
