<![CDATA[This study aims to determine the best concentration on the comparison of jackfruit skin starch and chitosan with the addition of virgin coconut oil (VCO) as a plasticizer and the characteristics of bioplastics. The research method consisted of the following steps: extracting jackfruit skin starch using two processes, namely the delignification process and the bleaching process. The production of bioplastics was carried out with the following treatments: Jackfruit skin starch: chitosan, each with a ratio of P1= 100%:0%; P2 = 85%:15%; P3 = 70%:30% and P4 = 55%:45% with the addition of VCO of 10% of the total starch of jackfruit skin and chitosan and stirred for 1 hour until homogeneous. The resulting solution was then printed on a glass mold with a size of 20 x 15 cm and dried in an oven at 60oC for 6 hours. The bioplastics were cooled at room temperature for 6 hours then removed from the glass plate and stabilized in a desiccator before being analyzed. Data analysis used the Completely Randomized Design (CRD) method with 4 treatment levels and three replications. The results showed that the addition of chitosan and VCO had a very significant effect (p<0.05) on the characteristics of bioplastics. The best treatment ratio was obtained in the ratio of jackfruit skin starch: chitosan 55%:45% with each thickness value of 0.1682 mm, tensile strength of 0.5933 MPA, 20% water absorption and 50% biodegradability test which can be degraded for 3 weeks.]]>
