The more rapid advancement of technology and the industry will be followed by the
increasing consumption on plastic materials that cause a buildup of plastic waste.
However, in general the plastic used is nonbiodegradable, so if dumped casually may
give rise to environmental pollution. This study aimed to know know how the addition
of a nano-type filler, against mechanical properties and biodegradability, bioplastic
and to know the optimum percentage in addition type nano Filler, against mechanical
properties And Biodegradability Bioplastic. Manufacturing of bioplastic by adding
filler, such as cellulose stalks of bananas, rice husk cellulose, cellulose and reeds. Use
the free variables as filler concentration i.e. 0%, 5%, 10%, 15%, and 20%. Analysis
of bioplastic covers test degredasi,% elongation at break and tensile strength, and
thermal properties using DSC. . The results from this research that the addition of
filler influence on mechanical properties and biodegradability bioplastic. Test results
are at optimum value degredasi the addition of a filler Pulp as much as 20%, and the
value of most excellent biodegradability bioplastic in addition cellulose filler banana
stems. As for the result value of the strong pull of bioplastic produced at the most
optimal addition of rice husk cellulose filler as much as 10%, i.e. a 4.97 N/mm2
elongation value and optimized resulting in the addition of cellulose filler reeds as
many as 10 % of 76.31%.
