Currently, there is a disparity between wood-log production from natural production-forest and their consumption for wood-processing industries, including pulp and paper factories. As the consequence, the Indonesia’s Ministry of Forestry has enacted the soft-landing policy, among others reducing the role of natural productionforest to supply wood for pulp/paper factories, and replacing it gradually by pulpwood plantation forests (PWPF) with species such as Acacia mangium, and Eucalyptus spp. In using PWPF woods, it is necessary to scrutinize particular aspects like proper exploitation factor of raw material (wood), basic wood characteristics, pulp-processing properties, and pulp-sheet qualities such that they can satisfy consumers. As the relevance, scrutiny has been realized through “the Determination of Optimum Technical Growth Rotation and Exploitation Factor of Plantation Forest (PF)’s eucalypt (Eucalyptus hybrid) wood as Raw Material for Pulp and Paper Viewed from Basic Wood Characteristics, Kraft Pulp-Processing Properties, and Unbleached PulpSheet Qualities”. As such, the eucalypt-wood samples were taken from North Sumatera with their varying tree-ages at 4, 5, 6, and 10 years. Results revealed that by reckoning those characteristics, properties, and qualities, the optimum technical rotation of such wood turned out to be 7.01-year age. The exploitation factor for eucalypt wood at that age was still unknown; and instead at 6 years old, the factor reached 95.5 - 97.5%. Therefore, further related investigation deserves carrying out to determine that unknown exploitation-factor. Nevertheles, all these scrutiny results might be beneficial for the government in determining the policy as well as for the PF enterprisers.
