Abstract :
Bioplastic is A plastic that naturally degraded by microbe or weather. Bioplastic
is derivered from renewable biomass resource. The aim of this research is to
obtain the effect of modified sugar palm fiber addition on the mechanical
properties of bioplastics included tensile strength, elongation at break, funtional
group using FT-IR, surface morphology using SEM and biodegradation. Fiber
serves as filler in bioplastic, in this research, the filler that used was modified
sugar palm fiber. Modified sugar palm fiber was soaked in 5% (w/v) NaOH to
lose the lignin contents. The production of bioplastic method that used in this
research was asting method. Variation of avocado seed starch and modified sugar
palm fiber composition ratio were 6: 4, 7: 3, 8: 2 and 9: 1 (w/w) and variations of
glycerol addition were 0,1; 0,2; 0,3 and 0,4 (v/w), tensile strength 3,46 MPa,
elongation at break 5,90%. From the result of FT-IR analysis indicated O-H
group, C-H group, C=O group And C-O group on bioplastics. The result of
mechanical properties were supported by Scanning Electron Microscopy (SEM)
showed the bioplastics with modified sugar palm fiber as filler and plasticier
glycerol have the fracture surfaces were compact. From the result of
biodegradation test, bioplastics was completely degradated within 12 days in the
soil.
