Abstract
In order to obtain bioplastics product form Musa paradisica formatyca concentrate, sorbitol and glycerol plasticizer substance is added. The purpose is to make bioplastics produces more flexible and more elastic. This study is conducted to determine the effect of the composition of sorbitol and glycerol plasticizer so that an optimal biodegradable plastics be able to obtain. The other ingredients utilized are acetic acid, chitosan, and aquedest. The method used for this study is mixing 100 ml of the essence of Musa paradisica formatypica, 0.7% chitosan (% v / v), 0.5% acetic acid (% v / v), 5 grams of cornstarch with plasticiser (0%, 1%, 2 %, 3%, 4%, 5% sorbitol and 0%, 1%, 2%, 3%, 4%, 5% glycerol) of the volume of essence of banana peel, then heated to 90ºC with a stirring speed of 300 rpm for 30 minutes. The results obtained in the form of thin sheets of bioplastic were tested mechanically in the form of tensile strength and percent elongation. Based on the analysis of tensile strength and elongation percent technique, it was found that bioplastics were close to the standard, i.e., in the sample 3% glycerol (% v / v) with a tensile strength of 46.4201 Mpa and percent elongation of 15.15152% and a sample of 5% sorbitol (% v / v) tensile strength 31.4228 MPa and elongation percentage 15.15152%.
