It had been conducted research on characterization the mechanical properties of biodegradable plastic composites from HDPE (High Density Polyethylene) and gembolo starch. This study aims to determine the mechanical characteristics of biodegradable plastic made from a mixture of HDPE and gembolo starch. In this study, the variation in HDPE mass ratio with gembolo starch used was 8:2; 7:3; 6:4; 5:5; and 4:6 grams. The characteristics of biodegradable plastics tested were tensile strength,
