The amount of plastic waste has increased because the use of a non-degradable plastics us packaging is growing. The problem of plastic waste can be above one of them with the use of biodegradable plastic that is easy to decompose in the soil. The effort to speed up the degradation of the plastic is done by replacing some or all of the material synthesis with natural ingredients. Arrowroot flour is one of the natural ingredients that can be used in the manufacture of biodegradable plastic because the charateristic are easily degraded in soil, many in amount and affordable price. To increase the strength, color clarity, elasticity and plastic degradation ability of these arrowroot plastic, glycerin is used as plasticizers and NaOH as factors add to it the value of the test of strength, as improving the clarity of the plastic colors and trigger an increase in the time of degradation. This research was conducted to find out how big the benefits of arrowroot flour in making biodegradable plastics in addition as one of the ingredients of the snacks in the community in Kudus. Arrowroot plastic researched by mixing flour arrowroot (3 g, 5 g, and 7 g) and glycerin (2 ml, 3 ml, and 4 ml) and NaOH ( 0 ml, 1 ml, and 2 ml) in 40 ml water. The addition of glycerin can increase the elasticity of arrowroot plastic. The addition of NaOH can be a trigger for an increase in the time of degradation in the soil. Optimum results of arrowroot plastic are obtained with the composition of the materials : 3 grams of flour, 4 ml of Glycerin, 2 ml of NaOH and 40 ml water. Characteristics of arrowroot plastic researched by using a test of strength with the results of 8 N, testing the elasticity of average results with 20% of the initial length and biodegradation tests with the final result 40 days.
