Abstract
This research aimed to utilize sorghum as a filler rod using variations of sorghum starch-chitosan formulations-filler with 10 wt% glycerol as a plasticizer. The physical and mechanical characteristics of bioplastics then analyzed by using Low Density Polyethylene (LDPE) as a reference. Variation of sorghum starch-chitosan formulations used were 10:0, 9.5:0.5, 8.5:1.5, 7.5:2.5, 6.5:3.5 and 5.5:4.5 (w/w), variations of the addition of sorghum stem powder filler were 0.25:0.5:1 g with gelatinization temperature on 95 , stirring speed of 375 rpm and temperature drying in an oven was 60 for 11 hours. Starch granule was sieved in 63 micron and stirred for 35 minutes. The best conditions obtained by variation of formulation starch: chitosan 7.5:2.5 (g/g) with 0.25 g filler addition and best tensile strength test was13.9957 Kpa. Keywords : bioplastic, filler, glycerol, modulus young, sorghum starch
