Macroscopic image database of Indonesian commercial timber “LignoIndo” has been developed to support the development of a computer vision-based wood identification system. A total of 809 wood species were taken their macroscopic images by using digital loupe at two magnifications: 50 times and 200 times. All of these timber species are Indonesian commercial timber listed in LIU (License Information Unit) in November 2016. Cross section images of 186 wood species listed in the Ministry of Forestry Degree No 163/2003 were also collected by using mobile phone camera that was attached with 60x magnify lens, as the basis data to the mobile application of automatic wood identification tool (AIKO). The number of wood species in this database will continue to grow as the number of commercial wood species increases. Besides, the number of replicates of specimens for each species of wood can also continue to be added to accommodate wood variations in the same species, the same species from different trees, and different geographic locations. This paper presents data collection methods and summaries of wood data that have been collected including trade name, botanical name, family, durability classes, strength classes, commercial class classification, conservation status, and recommended utilization.
Doubtlessly, wood identification is critically important for a number of sectors, including government organizations, the wooden-based industry, museums, law enforcement, and scientists working in the fields of botany, ecology, forestry, and wood technology. Unfortunately, most wood species listed as “the least-known species” lack essential knowledge or even their anatomical feature and basic properties to promote their usage. This research aimed to investigate the anatomical characteristics and fiber quality of the least-known timber species of Apocynaceae family, which are authentic wood collection from Xylarium Bogoriense, namely , Ervatamia. sphaerocarpa, E. aurantiaca, Kopsia flavida, Lepiniopsis ternatensis, Plumeria acuminata, P. rubra, and Voacanga foetida. Wood samples have indistinct growth ring boundaries, diffuse-porous vessels in diagonal and/or radial pattern, vessels in radial multiples of 4 or more cells, simple perforation plate, alternate intervessel pits; distinct borders of vessel-ray pits, similar with those of intervessel pits in size and shape throughout the ray cell, and septate fibers with simple pits to minutely bordered pits which are common in radial and tangential walls. Based on the fiber length and the derived values of fiber dimension, some species are classified into Quality Class II and III, and the rest of them are classified into Quality Class II or III for pulp and paper manufacturing. Based on general characteristics, commonly Apocynaceae can be used as handicrafts raw material. Based on the fiber quality, some species which are classified into Quality Class II, are predicted to have potential as pulp and paper material with medium quality.
