Abstract

Biocellulose can be made by fermentation of coconut water by Acetobacter xylinum. Microorganism. Several developed countries have been starting to research the use of biocellulose as a bio-cellulose that is easily broken down in the world of plastics or membranes, such as edible films and biocellulose membranes. In this study, the biocellulose produced from fermenting at room temperature for 15 days using nutrient-enriched coconut water was converted into cellulose membranes. The treatments in the fermentation process were variations of sugar (10%, 11%, 12%), variations in nitrogen sources using ammonium sulfate (0.3%, 0.4%, 0.5%) and variations in mineral sources using MgSO4 (0.10 %, 0.11%, 0.12%). The optimum results obtained in the experimental volume of 1 liter were in the condition of 12% sugar media, 0.5% ammonium sulfate and 0.12% MgSO4 where the biocellulose results had a thickness of 1.7 cm, 63.50% yield and 4.41 fiber content. %. Conversion of biocellulose into a biocellulose membrane through pressing and drying The test results of the biocellulose membrane had a rejection coefficient of 63.24% and a flux value of 15.28 lt.m-2.hr-1
