Abstract: | Ampupu wood a fast growing species, has been a major raw material for pulp and paper production. Ampupu wood (Eucalyptus urophylla S. T. Blake) of 4, 5, 6, and 7 years old were determine the fiber dimension and chemical content of the wood. Pulp was then produced by Kraft pulping process. The operating conditions were active alkali of 17%, sulphidity of 30%, liquor/wood ratio of 4/1, maximum temperature of 1650C, and 3.5 hours total cooking time. The resulting pulp was then bleached by an ECF bleaching method following DEDD sequences. The result was determine fiber dimension and its derivative values, E. urophylla were classified into quality class of II for the raw material of pulp and paper. The age of wood influence chemical content but did not influence pulping yield and kappa number. It was found that the highest mechanical properties of pulp resulted from 6 years old E. urophylla. E. urophylla of 7 year old have stain on the sheets of pulp so it's poorly to used as raw material for pulp and paper |
