PREPARASI DAN KARAKTERISASI MIKROKRISTALIN SELULOSA DARI LIMBAH SERBUK KAYU PENGGERGAJIAN
ABSTRACT: A study
on the preparation
and characterization of
microcrystalline cellulose from waste
of sawdust has
been carried out.
A total of 300 grams
of sawdust made
into lphacellulose by multistage
pulping method and hydrolyzed by using hydrochloric acid to produce microcrystalline cellulose,
which was characterized
further. Microcrystalline cellulose obtained as much as 99 grams with a
yield of 33%. The organoleptic characteristics
were fine powder, white,
odorless, and tasteless.
Identification with a
solution of iodinated
zinc chloride produced a
blue violet and
the infrared spectrum
produced nearly the
same wavenumber with Vivacel PH 102®. Solubility in water was
0.117% and the pH was 5.08, dissolved in a solution of
ammonia-copper tetramin. The loss on drying
was 5.85 %, the bulk density was
0.329 g/ml and tapped density was
0.542 g/ml. Carr's index value
was 39.60%, Hausner ratio
was 1.656 and
Hydration capacity was
3.191. There was
no starch on
this microcrystalline cellulose. Microcrystalline cellulose from waste
of sawdust generally met the pharmacopoeia
requirements and the
characteristics were not
significantly different from Vivacel PH 102®.
