Pengaruh Variasi Komposisi Acacia Crassicarpa Dan Eucalyptus Terhadap Kualitas Dan Rendemen Pulp Kraft

---

ABSTRACT
The increasing demand of pulp in the world requires sufficient availability of raw
materials. To fulfill the raw material supply, it can be established through
development of industrial plantations [HTI]. Acacia sp and eucalyptus sp are the
types of wood that are prioritized for development in industrial plantations
because these species are fast growing species, high timber production, and do
not require high living requirements. The study was conducted on a mixture of
Acacia crassicarpa and eucalyptus raw materials with the compositions are 75%
Acacia crassicarpa : 25% Eucalyptus, 50% Acacia crassicarpa : 50% Eucalyptus
and 25% Acacia crassicarpa :75% Eucalyptus. Pulping is done by means of a
kraft process. The best cooking conditions and meeting the kappa number target
17 ± 1 were obtained in the variety of raw materials for 25% Acacia crassicarpa
and 75% eucalyptus [AC:EH-25:75] with active alkali concentration 18%,
temperature 165 oC, ratio 1: 4 and H factor 800 with screen pulp yield 50,52%,
brightness 36,96% ISO, viscosity 1045 mL/g, and productivity 248,6 kg/m3 where
in this variation the composition of the wood used contains more eucalyptus than
Acacia crassicarpa. Eucalyptus wood has a higher density resulting in a higher
productivity.
Keywords : acacia sp, eucalyptus sp, Acacia crassicarpa, active alkali, h factor,
screen pulp yield, brightness, viscosity, productivity, density.
