Dimas Dwi P Nugroho is presenting on fibers and wood supply. He discusses natural fiber sources including plants, animals, and inorganic materials. Plant fibers come from wood, non-wood, and grass sources. Wood supply can come from mixed tropical hardwood harvested from natural forests or from wood plantations which require higher investment but provide more sustainable and higher quality wood. The presentation covers fiber structure, types of wood and wood densities, and the logging, loading, and unloading process.

Fiber Structure

6. @dp_dimaz
Cell wall structure: Primary wall +
Secondary wall
Chemical composition of the walls:
Compound middle lamella: mostly
lignin; Primary wall: lignin,
hemicelluloses and cellulose (Lignin
component is slightly higher, See Fig. b)

WOOD SUPPLY :
-Mixed Tropical Hardwood
Lowest investment
Harvesting
inhomogeneous
Unstable product quality
High cost production
-Wood Plantation
High investment
Nursery – Planting – Handling - Harvesting
Business continuously
Best Manage
Good for climate
