Abstract

One source of isolated or frequently extracted vegetable protein is soybean. Using an extruder, a method of extrusion is used to create mixed bioplastics. Biodegradable plastic seeds are produced by extrusion following the drying and pelting stages. A mixing process that tries to make the material homogenous and evenly distributed can be carried out using an extruder machine. Because of the characteristics of bioplastics with low water resistance and plastics that disintegrate easily This work aims to identify the ideal parameter variations for water resistance and biodegradation in extrusion machines, as well as the impact of parameter changes in the production of LDPE-soybean seeds on bioplastic seed yield products. This study’s primary materials are Low-Density Polyethylene (LDPE) and biodegradable plastic made of tapioca, protein-rich soybeans, and glycerol. It blends in the extruder machine and then uses compression molding to print the specimen, which has the following dimensions: 20 mm in length, 20 mm in width, and less than 1 mm in thickness. The specimen then measures the water resistance test results and the irreversible bioplastic pellet’s biodegradation values. Taguchi method was used to conduct the experiment design and to achieve the data processing. Three variables used are barrel temperature, composition, and screw rotational speed. Based on the conducted experiments, it has been determined that the ideal values for each water resistance parameter are at 135 C for level 3-barrel temperature, 30 rpm for level 1 screw rotation speed, and 0/100 for level 1 composition. The temperature of 95 degrees Celsius is the ideal level for biodegradation. Level 3 composition is 85/15, and the level 3 screw rotates at 50 rpm. Temperature and the composition of the material are characteristics that significantly affect water resistance, whereas temperature and the composition of the material significantly affect biodegradation.
