Evaluation of the Biodegradation for Oil Absorbed Cassava Starch Film Filled with Kenaf Core Fiber

Abstract

Cassava starch (CS) films filled with different loading of kenaf core fiber (KCF) were prepared and tested. Two tests were carried out; oil absorption test and biodegradtion test. The oil absorption test were carried out with different loadings of KCF (0%, 0.2, 0.4, 0.6%. 0.8% and 1.0%). The results showed an increase of oil intake as the kenaf loading increased. The biodegradation test was conducted via soil burial method. Two sets of film samples were tested; film samples with and without immersion of oil. Each set of the film samples recpectively compares between CS films with and without KCF loadings. The results of the biodegradation tests showed that CS films with KCF had lower amount of weight loss compared to CS without KCF. Furthermore, the result of biodegradation tests for film samples immersed in oil were lower compared to film samples with oil immersion.
