Abstract

Rubber cassava is a plant that underutilized due to toxic HCN that contained in it, it has very high carbohydrate content that is 98.47% sorubber cassava can be as basic material of manufacturing of biodegradable plastic. This research was did to determine the effect of composition of sorbitol and glycerol plasticizer and obtained an optimum composition with using addition materials such as chitosan, acetic acid, and aquadest. Utillization of Sorbitoland glycerol plasticizer varied with comparation of 40% fromweight starch with 5% of each sample interval. The results obtained in the form of an edible film of biodegradable plastic that tested mechanical properties and biodegradation test for 60 days. Based on analysis of the tensile strength test, biodegradable plastics obtained from rubbercassavastarch that optimum namely with composition of 25% sorbitol and 15% glycerol by0.00613 Mpa. Based on analysis of elongation test, biodegradable plastics obtainedfrom rubbercassavastarch that optimum namely with composition of 15% sorbitol and 25% glycerol by 5%.Based on analysis of biodegradation test showed that biodegradable plastic with optimum condition that tested with the land medium has been degraded perfectly for 60 days while with the river, sea, wells, rain,brackish, and sterilled water media can be degraded just needed longer time for plastic can degraded perfectly
