EKSTRAKSI ABU KAYU DENGAN PELARUT AIR MENGGUNAKAN SISTEM BERTAHAP BANYAK BERALIRAN SILANG
Abstract: As an agricultural
country, Indonesia has natural resources are very abundant , one of which is
wood . Wood ash from household and industrial waste has not been used , whereas
according to Pitman high potassium content . The solubility of potassium
carbonate in high water , so effective when extracted with water . However,
high humidity in Indonesia drying wood for fuel so low that allegedly affect
the quality of the ash obtained . In this research, the extraction of wood
ashes with water using a solvent system gradually many wing cross.
The experimental study was conducted in a university laboratory Ahmad
Dahlan , Yogyakarta . The procedure used is the extraction of wood ash 200 ,
300 and 400 grams with 1000 ml of solvent water for 5 minutes using a glass
beaker , filtering with the aid of a vacuum pump , and acidi alkalimetri analysis
using 0.1 N HCl residual solids by filtration and then in water kontakkan again
and so do the same thing 5 times . Raw materials derived from wood ash
combustion for drying of the wood cutting industry and water used in the form
aquadestilata .
Extract wood ash derived from the combustion for drying small normality
sawmill industry . The results of the analysis can be made curve that describes
the operating line and curve logarithmic form of the equation of equilibrium in
the form of linear equations . Moreover, it can be made a graph illustrating a
series of 5 stages of operation which is a combination of single phased
extraction.
