    Abstract

    The objective of this research was to study the diversification of nata de coco as edible biodegradable packaging and biocellulose. The experimental design used in this study was Factorial Completely Randomized Design that consisted of two factors. The first factor was drying temperatur (60, 80 C)and the second factor was drying time (6, 12, 18, 24 hours) for packaging. Factors for biocellulose were starter concentration (5; 7,5; 10%) and fermentation time (8, 10, 12 days). The result showed that the best biodegradable packaging from nata de coco made by 5 days fermentation, 24 hours drying at 80 C, had thickness 0,47 mm, water vapor permeability 0,129 g/m2hours, tensile strength 21,66 N, tensile stress 0,071, shearing stress 1,02, and compressive strength 4,87 x 106 N/m2. The 12 days of fermentation with 10% starter concentration gave the highest biocellulose yield (0,58%), water content 12,40%, and water holding capacity at romm and high temperatur were 766,67% and 1733,33 % respectively.
