PENGARUH TEKANAN PEMBRIKETAN DAN HOLDING TIME TERHADAP KARAKTERISTIK RELAKSASI BRIKET BIOMASA
Abstract: This research was
conducted to know the effect of briquetting pressure and holding time on
relaxation characteristic of
biomass briquette. Relaxation
characteristic from
briquette evaluated was
the percentage of
elongation in length
and the percentage increase
in volume. Biomass
used was Kalimantan’s
wood sawdust. Briquette was
conducted by using a hydraulic machine press and briquette die is in form of cylinder with the inner diameter of 3 cm.
Binder used was 10 % molasses and
particle size of biomass sawdust 50 mesh. The variation of briquetting pressure
used was
200 kg/cm2, 400
kg/cm2, 600 kg/cm2, 800
kg/cm2, and 1000
kg/cm2, whereas
variation of holding
time used was
5 s, 10
s, 20 s, 40 s,
and 60 s. The
testing of relaxation
characteristic used the
direct method based
on standard of ASAE S269.2 DEC 96. From result of
relaxation testing was founded that increased briquetting pressure
and extended of
holding time could
decrease elongation and relaxed volume of briquette biomass.
