THE CELLULOSE CONTENT OF THREE SEAWEED SPECIES AND ITS POTENTIAL FOR BIODEGRADABLE FILM PRODUCTION
Abstrak (Bhs. Indonesia)
Seaweed is abundant in Indonesian waters with coral reef substrates, but the utilization and processing of seaweed in Indonesia is still limited. The cell walls of seaweed primarily consist of lignocellulose. Its high cellulose content makes seaweed potentially valuable for various industries, notably in the production of biodegradable film material. The variables observed in this study were the seaweed species used and the quality of biodegradable films. This study was conducted using three different species of seaweed, namely Sargassum sp., Gracilaria sp., and Ulva sp. The objectives of this study were to determine the seaweed species with the highest cellulose content and to determine the quality of biodegradable films made from cellulose extracted from three seaweed species. The parameters analyzed included the percentage of seaweed cellulose content and the biodegradable film’s quality based on solubility, biodegradability, colour, odour, and texture. Cellulose was extracted from seaweed using a chemical extraction method. The film quality was evaluated through solubility test, biodegradability test, and organoleptic test. Data analysis was performed using one-way analysis of variance (ANOVA, multiple groups) with a significance level of α=0.05. The Kruskal-Wallis test was used if the data did not meet the assumption of a normal distribution
