The demand for hardwood pulp increased due to the limited hardwood in several countries and its advantage as raw material for paper or paper boards. The hardwood has a specific grafity ranging from low to high that causes the quality of pulp produced not uniform. The observation of specific gravity, fiber morphology, and chemical content of hardwood; and the quality of hardwood pulp have been done. FAO data were used to evaluate the fiber length, fiber wall, lignin, extractives, Kappa Number, and the quality of sulphate pulp. The sulfidity, active alkali, solid to liquor ratio, temperature, and cooking time of pulping process were 25%, 17%, 1 :4, 170°C, and 3.5 hours, respectively. The specific gravity of hardwood in the range of 0.30 to 0.99 was grouped into seven classes and analyzed by statistical regression. The specific gravity of the hardwood was associated withfiber morphology, chemical content, pulping, and pulp quality. The results showed that tha specific gravity of wood affects certain parameters with regression equation model that can be used for the selection ofwood raw materials for sulphate pulping. There is a tendency that the specific gravity can influence the hardwood fiber wall thickness, lignin content, pulp yield, Kappa Number, and the physical properties of pulp for tear and tensile srength.
