Abstract
This study aims to determine the effect of Poly vinyl alcohol (PVA) and Soluble soybean polysaccharides (SSPS), and to characterize it (water resistance and biodegradation test). This research was done by blending (mixing) PVA, SSPS, acetic acid, and maleic anhydride. From the results of infrared spectrum analysis on plastic films showed peaks in the area 1000-1100 cm-1 which indicates the absorption of polysaccharides. This plastic has an optimum water resistance of in the ratio between 1:1 w/w (SSPS:PVA). Optimum biodegradation test results in the ratio of 1:1 w/w (SSPS:PVA). Based on the result of the research, it can be concluded that water resistance and biodegradation reach optimal on composition 1:1 w/w (SSPS:PVA).
