Evaluation of Four Lesser-Known Indonesian Hardwood Species for Paper Pulp Production Based on Fiber Quality and Specific Gravity

The effort to ensure raw material sustainability in the paper pulp industry needs to focus on finding substitutes for wood species. Raw materials for making paper pulp can be obtained from all species of wood, but they must meet specific criteria. We analyzed the specific gravity and maceration preparations of four lesserknown hardwood species that grow in West Sulawesi as potential raw materials for the paper pulp industry. The study indicated that three lesser-known hardwood species (palado, kambelu, and kanduruan) were potentially useful as raw material for pulp paper making.
