This research aims to determine to study the ratio of Jerbung shrimp waste powder and purple yam starch in the production of bioplastics. This research used a Completely Randomized Design (CRD) with 5 levels of ratio of jerbung shrimp waste powder and purple yam, namely 0:5; 0.5:4.5; 1:4; 1.5: 3.5 and 2:3. Each treatment was repeated 3 times to obtain 15 experimental units. The results showed that the ratio of Jerbung shrimp waste powder and starch had a significant effect on tensile strength, elongation, thickness, water resistance and WVTR. The best bioplastic characteristics was best produced using the ratio 0.5:4.5 with tensile strength of 18.17 N/mm2, elongation of 68.06%, thickness of 0.35 mm, water resistance of 75.15 %, WVTR 22.29 g/m2.hour.
