Abstract :
This research aims to determine the
effectiveness of the use of pins chip mixture of acacia and
eucalyptus wood and the optimum condition of the
quality of the pulp. The cooking conditions for kraft pulp
were alkalinity (17%, 18%, and 19%) and sulfidity were
the same in each test (31.28%). Maximum cooking
temperature is 160°C for 3 hours, with H-Factor 800.
Bleaching of pulp pins chips using three processes,
namely D0, EOP, and D1. Pulp properties test consists of
physical strength and optical test. The ripening
conditions for kraft pulp resulted in a fairly high pulp
yield of about 50.93% at 17% active alkaline charge
condition, 51.07% at 18% active alkaline charge
condition, and 51.42% at 19% active alkaline charge
condition. The use of acacia and eucalyptus pins chips
was effective enough to produce a fairly high yield with a
range of 40-55%, with the lowest kappa number 1.12 and
the highest 1.23. The effect of increasing the
concentration of alkali is more effective at 19% active
alkaline charge conditions, but the resulting viscosity is
very low, as well as 17% active alkaline charge conditions
are less effective but the viscosity is quite high. The ideal
conditions of active alkaline charge are 18% with 50.93%
pins chip yield, 720 cm3/g viscosity, and 89.03% ISO
brightness. In general, different concentrations of active
alkali charge white liquor affect the physical strength
and optical properties.
