The Effect of Additional Chitosan and Cellulose on The Performance of Bioplastic from Manihot Glaziovii Starch

Manihot Glaziovii has a starch content of 77.87 making it potential to be used as raw material for bioplastics manufacturing substitute conventional plastics. It requires the addition biopolymers (fillers) and plasticizers overcome weaknesses against mechanical properties water resistance. This study aims determine effect filler variations on quality compared with SNI No.7188.7:2016 using fillers in form chitosan cellulose from newsprint sorbitol plasticizer were expected improve bioplastics. Melt intercalation method are heating temperature 60°C-80°C 60 minutes stirring speed 500 rpm. The variation combination 30% (w/w starch) was 10%, 12%, 14%, 16%, 18% while 16% 20%, 30%, 40 %, 50%, 60%. Based test results, best characteristic value absorption is 120.65%, biodegradability 32.74%, tensile strength 15.72 MPa, WVTR 6.52 g/m2.hour, elongation 29.76%. From can concluded that made have not been able meet No.7188:2016.
