Abstract

The increasing use of plastics in our daily lives cause environmental pollution. Hard synthetic plastic degraded by nature so it takes them environmentally friendly plastics are made from starch. In this research, biodegradable plastics from corn starch with sorbitol as plasticizer was synthesized. The purpose of this research are to determine the effect of sorbitol on morphological structure, mechanical properties, bioplastic resistance to EM4 and burial in the soil. Bioplastics are made from starch-distilled 1:5 added and acetic acid of 2 ml. Whereas the effect of sorbitol tested by adding to the solution of 0 ml, 5 ml, 10 ml, 15 ml and 20 ml. The structure of morphology increasingly smooth as sorbitol increase. The bioplastic mechanical properties are characterized by tensile strength, elongation and modulus young test and biodegradation tests performed using EM4 and burial in the soil. From result of research result of tensile strength test 2,56 MPa, for elongation 30,58% and 2,42 MPa for modulus young. The biodegradation test of EM4 showed that bioplastics were heavily degraded by 62.40% for three days and most of the bioplastics had been decomposed in the soil for seven days.
