| dc.description.abstract | The use of disposable food packaging such as styrofoam often causes
environmental problems due to plastic pollution that is difficult to decompose. One
solution to overcome this is the production of biofoam. This study aims to determine
the effect of varying additions of water hyacinth fiber and polyvinyl alcohol on the
characteristics of biofoam made from durian seed starch and to determine the best
treatment from varying fiber concentrations (0%, 10%, 15%, and 20%) and varying
PVA concentrations (20% and 30%). The results showed that the best treatment was
S3P1 with a fiber concentration of 15% and PVA concentration of 20%, which
produced biofoam with low absorbency, high density, and good biodegradability.
This indicates that the combination of water hyacinth fiber and PVA has the
potential to substitute styrofoam. | |
