Abstract

Ervian Jan Marudin / A420130022. Utilization of Cassava Rubber for Making Bioplastics withAddition Plasticizer Different Glycerol and Sorbitol. Essay. The Faculty of Education, University of Muhammadiyah Surakarta. August, 2017. Bioplastics are environmentally friendly plastic that can be degraded by the activity of microorganisms and produce water and compounds are not harmful to the environment. This bioplastic is made using rubber cassava starch, plasticizer glycerol serves to the elasticity of the plastic, and sorbitol serves to mechanical properties such as resilient and strong. The purpose of this study determine tensile strength, elongation at break and organoleptic bioplastics. The method used was completely randomized design (CRD) with two factors: the volume ratio of glycerol which is 3 ml, 5 ml, 7 ml and sorbitol is 2 ml, 4 ml, 6 ml. The results showed that the highest tensile strength at treatment 3 ml of glycerol and 2 ml sorbitol (G1S1) amounted to 17.20 N / mm2,then to the weakest tensile strength results in the treatment of 7 ml of glycerol and 4 ml sorbitol (G3S2) by 2.82 N / mm2.Elongation at break of the most powerful in the treatment of 7 ml of glycerol and sorbitol 2 ml (G3S1) 66.67%, and the weakest results in the treatment of 5 ml of glycerol and sorbitol 2 ml (G2S1) amounted to 24.00%. Organoleptic include texture (smooth 8 and 1 bit rough), color (8 nodes and one white), and the level of preference of 15 panelists to express love or are interested in bioplastics. Keywords:Bioplastics, glycerol, cassava rubber, and sorbitol
