Assessing ultrastructure and density properties to predict wood hardness of young fast grown plantation teak
Publisher: IOP Publishing
Date: 09-2020
DOI: 10.1088/1757-899X/935/1/012026
Abstract: The use of plantation timber has been increasing to supply raw material for timber manufacturing. Super teak ( Tectona grandis Linn. f), a fast grown teak planted in Indonesia was successfully harvested in very young age (5 years old). This frequently rises queries whether the young super teak could meet the minimum quality criteria for wood working. Investigation on wood properties should be undertaken to measure the required wood properties. However, physical and mechanical testings require a long time process and large size s les. Therefore, a non-destructive method to predict wood properties of standing trees need to be developed. This study aims to assess ultrastructure and density properties to predict wood hardness of young fast grown plantation teak. S les were collected from super teak plantation in East and West Java. Crystallinity and its quantifiers were measured using X-Ray Diffraction. The hardness was determined using an Instron® universal strength testing machine. The result showed that wood density was significantly related to wood hardness for all structural directions the power relationship explained 52-56% of the variation. Degree of crystallinity (DC) and crystallite width were found as parameters affecting wood hardness. DC was positively correlated to wood hardness for all structural directions (r=0.2 r 2 =0.04), whereas crystallite width was negatively correlated to radial and end-grain hardness (r=0.2 r 2 =0.04). The power of prediction increased only by 1-5% when crystallinity factors were included with density, thus the extra effort of using XRD is not warranted for non-destructive prediction of wood hardness.

Inventory of wooden ship materials and determination of its alternative materials through wood properties approach: Case studies in the Riau Islands, the Northern and Southern Coast of Java
Publisher: IOP Publishing
Date: 2020
DOI: 10.1088/1755-1315/415/1/012014
Abstract: Indonesia is an archipelago country with approximately two-thirds of its territory consisting of oceans, so that inter-islands transportation has become one of the most important economic aspects. Traditional wooden ships are commonly used by local people in the coastal areas for transportation to support their needs. Several wood species which have high durability are commonly used for making wooden ship component such as Eusideroxylon zwageri (ulin), Vitex sp. (laban), Tectona grandis (teak), and Instia bijuga (merbau). This study aims to determine the alternative materials for wooden ship based on inventory at the Riau islands, the Northern and Southern Coast of Java. Exploring the alternative materials for wooden ship is important to optimize the utilization of lesser- and least-known timbers and address the problem of decreasing supply of major commercial timbers. This study has identified many wood species used by coastal fishermen for making wooden ship. Identification of wood species was carried out using microscopic observation based on IAWA standard, while the determination of alternative materials was undertaken through wood properties approach. The results show that there were various wood species used as raw materials for ship components. Some identified wood species are Tectona grandis (teak), Shorea sp. (balau and light-red meranti), Dichrostachys cinerea (pung), Ormosia subseraceae (kupang), Lumnitzera littorea (teruntum), Alseodaphne sp. (medang). Several alternative wood species to substitute current materials are elaborated in the paper.

DOI: 10.1088/1755-1315/528/1/012048
Abstract: Biological pulping is an environmentally friendly process for making pulp and paper whereby the wood raw material is pre-treated with selective delignifying white-rot fungi. Therefore, the purpose of this study is to determine the decay patterns of white-rot fungi Polyporus arcularius and Pycnoporus sanguineus , as well as its ability to decay Hevea brasiliensis (as hardwood) and Pinus merkusii (as softwood) by observing the anatomical characteristics. Fungal attack testing on wood was carried out by the Kolle-flask method with a variation of 6, 9, and 12 weeks incubation time. The structure of wood cells was analyzed using wood incision method, followed by a combination of safranin-picro aniline blue and safranin-astra blue, and maceration method. The results showed that H. brasiliensis wood has a higher percentage of weight loss than P. merkusii wood. Wood attacked by P. sanguineus showed a higher weight loss compared to the P. arcularius . The decay pattern of P. sanguineus infected wood was concluded as selective delignification in P. merkusii and simultaneous delignification in H. brasiliensis while those infected with P. arcularius both performed simultaneous delignification. In the early stages of decay, selective delignification is characterized by the formation of intercellular space due to degradation of lignin in the middle lamella, while simultaneous delignification is characterized by cell wall thinning. The anatomical structure of H. brasiliensis attacked by the white-rot fungi showed differences with P.merkusii , whereby the ray cells of P.merkusii wood was more degraded than in H. brasiliensis .

DOI: 10.59465/IJFR.2023.10.1.75-90
Abstract: 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 s les 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.

Publisher: IOP Publishing
Date: 11-2020
DOI: 10.1088/1755-1315/591/1/012036
Abstract: Gorontalo, one of the provinces in Indonesia, has not been widely known for its potential of wood fossil. The anatomical structures observation and the age estimation were conducted on two specimens of wood fossils buried in Tohupo Village, Bongomeme District, Gorontalo. The anatomical features of wood fossils were observed through thin slices of the cross, radial, and tangential sections using a Carl Zeiss-Axio Imager-A1m microscope. The description of anatomical features referred to the IAWA (International Association of Wood Anatomists) list of microscopic features for hardwood identification. The age estimation of the wood fossils was based on Geological Map (scale 1: 100.000) of the Tilamuta sheet, Sulawesi. Based on anatomical structures observation, the species of wood fossils were identified as Hopenium sp. ( merawan /hopea) and Shoreoxylon sp. ( balau) . The estimated age of wood fossils was 3.6 to 1.8 million years before the present (BP) (between the late Pliocene and Early Plistocene periods).

DOI: 10.1088/1755-1315/374/1/012057
Abstract: 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.
