Optimasi Kecepatan Pengadukan pada Proses Pembuatan Biodiesel dari Minyak Jarak Pagar (Jatropha Curcas Linneaus)
Abstract: This research is
about the effect of mixing velocity to produce biodiesel from jarakpagar oil
(Jatropha Curcas Linneaus). This research have conducted atTechnological
Laboratory of Natural Materials and Mineral of ChemicalEngineering of Riau
University. The research focusing know to learn effect ofmixing velocity to
produce biodiesel from jarak pagar oil using commercial K2CO3catalyst which was
blazed in a temperature of 600 ̊C. The
biodiesel productionconducted through two phases process i.e. esterification
and transesterification withthe mixing velocity 100 rpm, 150 rpm, and 200 rpm
during 1 hour for each mixing.The biodiesel characteristic is analyzed methods
to Erliza Hambali, and friends;Gubitz, et al; Haas and Mittelbach; and Azam, et
al. The research results shows thatthe yielding biodiesel meet to the
characteristic quality standard of biodiesel. Thebest mixing velocity is about
150 rpm with density 0.875 g/cm3, viscosity 0,11 cSt,level of water 0.025% b/b,
acid number 0.78 mg KOH/g oil, level of free fat acid(FFA) 0.39%, lathering
number 195.44 g KOH/g oil, iod number 87.71 g I2/100 goil and cetane number
54.49.
