Abstract

Abstract: Plastics generally cause global-scale problems because they cannot be degraded into the environment and causing a build-up of plastic waste. Biodegradable plastic material can be an alternative to solve the problem because of its nature which is easily naturally degraded by microorganisms. One of the natural wastes that can be utilized to become fillers in plastic mulch so it is more easily degraded is cornhusk because its utilization is still limited and cornhusk has high cellulose content. In this study, the extraction of cellulose was carried out on cornhusk to obtain cellulose by the alkali method. There was a decreased in hemicellulose and lignin levels, which indicated that the extraction process was quite successful. Then in the process of making biodegradable mulch films, Tinuvin P was added as an anti-UV agent and oleic acid was carried out as plasticizer and with several variations. The results show that the addition of anti-UV agent P and addition of oleic acid reduces the mechanical properties of biodegradable mulch and can control the rate of degradation of the biodegradable mulch film.
