Synthesis and Characterization of Biodegradable Plastic with Basic Materials of “Singkong Onggok” - Pectin Peel of “Jeruk Bali” (Citrus Maxima) – Plasticizer
Biodegradable plastic made from pectin pell of “jeruk bali” has been carried out. Pectin is obtained by extraction methods and for the manufacture of biodegradable plastics with hot-blending methods. The characteristics of the mechanical biodegradable plastics are determined by tensile strength and elongation, and biodegradation test of biodegradable plastics. The results of manufacture biodegradable plastic with the addition of pectin 5g was the best result with a tensile strength value of 195.35 MPa, and an elongation value of around 15.73 - 33.40%. Plastics with the variation of sorbitol starch composition as much as 1.5 g with 1 ml sorbitol each having a tensile strength of 61.29 MPa and elongation value of 14.30%. Plastic with a variation of 1.5 ml sorb itol has a tensile strength value of 118.93 MPa and an elongation value of 16.73%. Plastic with a variation of 2 ml sorbitol has a tensile strength value of 79.67 MPa and an elongation value of 17.63%.
