The Effect of Glycerol and Chitosan Variation Composition on the Quality of Biodegradable Plastics from Sugar Palm Starch (Arenga pinnata)

Bioplastics are plastics that easily degraded in nature, which can minimize their potential as pollutants. It is mainly made from agro-polymers such cellulose and starch. Starch sugar palm (Arenga pinnata) has the gelatinization principle requires bioplastic raw materials by adding glycerol chitosan. This research aims to determine effect of addition chitosan composition variation on mechanical properties. The method used a completely randomized design factorial (RAL-factorial) with one treatment factor carried out 2 stages. first step was mixing 4 grams starch variations (5 grams, 6 7 grams). second (2 mL 3 mL). Based data provided statistics nature tests, it could be concluded more volume added, value tensile strength will increase; contrary, elongation at break, air resistance, biodegradation increases. resistance 109.37%, 5 grams. 11 Mpa 6.67%, increase 79%
