Abstract


Based on previous research on electrical analysis of electrolyt pastes from durian husk waste as
biobatteries that generate an electric voltage about 1.5 volts.
Researchers want to develop durian
husk
waste material to commercial that was increasing the electrical voltage with nanotechnology.
It was  known that when the particle size
went to the nanometer scale, this phenomenon affects
some material properties, one of which was the increase in electrical conductivity.
The nanomaterial derived from durian
husk waste as a biobattery was synthesized by coprecipitation
method which was one of development methods of nanotechnology. Based on the analysis of SEM
and XRD characterization data of durian
husk waste powder, it was concluded that the results of
the synthesis process using the coprecipitation method obtained powder which has crystal size
about 5 nm. Phase composition contained in durian skin waste nano powder is dominated by
phosphate (PO4) elements, namely aluminum phosphate, aluminum silicate hydrate, and
titanium nitrate, but evenness of particles still tends to occur agglomeration or clumping caused
by oxygen. It can be concluded also that the higher and longer heating treatment the morphology
 of the durian husk waste particles more evenly and minimize the occurrence of agglomeration.

Keywords:  copresipitation method, electrical properties, nanopowder of durian  husk waste, and phase composition
