| dc.description.abstract | Research has been conducted on bioplastics using durian seed starch, chitosan, corn
Research has been conducted on bioplastics using durian seed starch, chitosan, corn
husk fiber, glycerol plasticizer, and 2% acetic acid solution as a catalyst. With
variations of durian seed starch and chitosan used are (30%: 70%, 40%: 60%, 50%:
50%, 60%: 40%, 70%: 30%), variations of corn husk fiber used are (0%, 2%, 4%, 6%,
8%) and using glycerol variations of 60%, 80%, 100%. By using the melt intercalation
method with bioplastic drying at 65˚C within 24 hours. The purpose of this study was
to determine the characterization of durian seed starch including starch content,
moisture content, fat content, and protein content and to determine the effect of the
addition of corn husk fiber and also the effect of glycerol variations on bioplastic
characteristics including thickness, density, tensile strength, elongation, water
absorption, Scanning Electron Microscopy (SEM), Fourier Transform Infra Red (FT IR), and degradability. The optimum results of bioplastics are found in the FBC2
sample using 100% glycerol with a variation of durian chitosan seed starch 40%: 60%
with the addition of 2% corn husk fiber, with a thickness of 0.324 mm, the elongation
at break value is 81.80% which increases as the glycerol used increases. However, the
density value of 1.45 g/cm3, the water absorption value of 44.7% and the tensile
strength of 0.29 Mpa decreased as the glycerol used increased. SEM test results show
a fairly even bioplastic surface, FTIR test results on bioplastics show the same
functional groups as the composition of the material and the absence of new functional
groups. | en_US |
