Reformulasi Sintesis Bioplastik Berbahan Baku Kulit Singkong (Manihot esculenta) serta Analisis Sifat Fisiknya

Abstract

Plastics are materials consisting of small molecules called monomers bonded to form larger molecules called polymers, and plastics are generally made from fossil fuel derivative products. Plastics have several favourable characteristics such as high elasticity, lightweight, and relatively low prices, making them highly reliable in various aspects. However, its increasing and unstoppable existence ends up polluting the environment. Therefore, there is a need for a breakthrough to develop environmentally-friendly plastics and have quality commensurate with commercial plastics. This research was proposed to modify the bioplastic formula made from cassava peel to obtain physical properties close to commercial plastics. The method for reformulating this bioplastic is to reduce the cyanide content in cassava peels and optimize the copolymerization process and the casting stages of bioplastics. According to the research results, the best interpretation of the physical properties of bioplastics is that they are processed at a temperature of 120 – 160; the addition of plasticizer as much as 5% (v/w) produces bioplastic with a strength of up to 15.190 mPa.
