Abstract

Plastic become a serious problem for the environment because of their nature which is difficult to degrade by microoganism. So there needs to be a solution to overcome this and scientists have found several ways to reduce this problem and one of them is using bioplastic. The development of bioplastics from organic materials has been largely done from starchy materials. The selection of rubber cassava is due to the abundance and lack of use of rubbery cassava itself. Therefore in this study was conducted to study the manufacture of bioplastic from rubbery cassava tuber starch. This bioplastic is made from starch for several reasons, among others, plastics made from starch / biomass will more easily decompose by nature and the abundant amount and the lack of utilization of rubbery cassava. The raw material in the manufacture of bioplastik is rubbery cassava starch. This research was done by isolating the rubbery cassava starch to get the starch. Then mixing with aquadets, chitosan, acetic acid, and glycerol with starch (5, 6, 7, 8, 9 gram) and glycerol (2, 3, 4, 5, 6 ml). After obtaining the plastic film layer is tested to its charatelistic such as tensile strength test, elongation test, biodegradation test and statistical test to strengthen the data obtained. From the research that has been done, the mechanical properties of plastics for elongation test showed that the composition: 7 grams of starch, 4 ml glycerol, with elongation of 32% and then the loop obtained 35% elongation with the same composition, tensile strength test obtained composition: 7 grams of starch, 2 ml glycerol, with a tensile strength of 1.85094 MPa and then the repeating obtained tensile strength 1.70609 MPa with the same composition, while for biodegradation test found 100% degradable plastic for 10-11 days with a composition of 9 grams of starch, 4 ml glycerol.
