Making plastics biodegradable is a casting ( method mold ) with the addition of a plasticizer glycerin through 3 stage of starch that is making tofu dregs of starch , making plastics and analysis of biodegradable plastic biodegradable sample ( thickness , tensile strength , biodegradability test , a test of endurancewater ) .The results of analysis sample is the thickness of plastic 0,40 mm; strong pull 0,0126 Mpa; test endurancewater 91,22 resilience % and biodegradability test for 7 days. Keywords: the plastic, biodegradable plastic, dregs tofu, tensile strength, biodegradability
