A study of teak wood quality from community forests in Gunungkidul III. Physical properties

The objective of this work is to explore the variation of physical properties of wood from teak trees grown in 3 different sites (Panggang, Playen, Nglipar) from community forests of Gunungkidul Regency. The measured parameters were green moisture content (GMC), basic density (BD), and linear as wel...

description The objective of this work is to explore the variation of physical properties of wood from teak trees grown in 3 different sites (Panggang, Playen, Nglipar) from community forests of Gunungkidul Regency. The measured parameters were green moisture content (GMC), basic density (BD), and linear as well as volumetric shrinkage. The three trees were collected at each site then were divided into three axial parts i.e. base, center, and top of the trees. Further, each axial part was divided into 3 radial positions i.e. near pith, middle, and near bark. The range of BD and GMC values were 504-672 kg/cm3 and 47-125%, consecutively. The result of analysis of variance showed that samples of Playen at the top parts tended to give higher average values of all physical properties measured as well as the samples at near bark of radial position. Samples from Nglipar exhibited the lowest range of GMC values (47-70%) whereas the highest values in the radial direction were observed in the near pith samples (100.51%). The range values of longitudinal, radial and tangential shrinkage were 0.39-0.88%; 2.75-3.93%; and 4.30-6.68%, respectively. By analysis of variance, site factor significantly affected of which samples of Nglipar showed the lowest levels of longitudinal and tangential shrinkage. The total shrinkage values were 5.26-15.07% as the T/R ratio were 1.38-2.13. In general, the BD levels of teak from Gunungkidul were comparable to those reported for conventional for teaks plantation and higher than those of young tissues cultural teaks. However, attention should be taken as the high magnitude of shrinkage as well as dimensional stability showed by several samples in this experiment.
