Abstract

Tracking timber on teak and teak wood products can be conducted using different methods, such as DNA finger printing, chemical composition of the wood, Near Infra Red spectra (NIR) and stable isotopes. Samples were collected from wood material and leaves in Java (9 Forest Management Units district) of Perhutani to determine: i) pattern of genetic variation within and among populations, ii) to determine the protocol for DNA extraction from wood, and iii) to study the feasibility of DNA marker for timber tracking in the field. Results show that: i) genetic variation of cpDNA (PCR-RFLP) is low, while RAPD variation is moderate, ii) there are differences in chemical composition of wood among the Forest Management Units (FMUs) of Perhutani, iii) variation of isotopic carbon and oxygen in Central and East Java were higher than from of West Java, iv) absorbtion intensity of NIR in West Java was higher than for Central and East Java, and iv) testing of DNA marker showed that genetic structure in the forest site is not significantly different from that in log yards, indicating that the timber flow is still according to the procedure. RAPD marker also is able to determine the origin of illegal timber and wood in industry without clear identity. Keywords: genetik marker, teak, timber tracking

Abstract

Cement board is a composite wood product has advantages such as fire resistance, termite, water resistant, and has good sound insulation properties. Bamboo is suitable material that can be used as a raw material of cement board. The objectove of this study was to determine the physical-mechanical properties of wool cement boards from betung bamboo (Dendrocalamus asper) in various densities. Mechanical testing included nondestructive testing performed using the sound waves velocity method (stress wave velocity). The material used was particles of wool/ excelsior dimensions. The adhesive used was Portland cement type I by the ratio of bamboo: cement: water 1:2:1. Target board densities were 0.5 g/cm3; 0.8 g/cm3; and 1.0 g/cm3. The results showed the higher density of the board the higher mechanical properties of boards. The difference density cement board was more influential on mechanical properties (MOE, MOR, SW) board compared with those physical properties. Nondestrcutive testing using sound waves velocity method can be used to predict mechanical bending properties of wool cement board of betung bamboo as indicated by the close relationship between the parameter estimators (dynamic MOE) and static testing value (MOE and MOR).

Abstract

Anatomically, bamboo is constructed from many types of cells. Vascular bundles are the cells which give the highest contribution to the bamboo strength, thus the density distribution of vascular bundles could be used as the main variable for analyzing the layer system of bamboo strip and laminated bamboo. The density of vascular bundles distribution decreases gradually from the outer to inner part in a regular manner which could be fitted by linear or nonlinear function. Ratio of modulus of elasticity (E) which widely used in transformed cross section (TCC) method for analyzing the layer system are substituted by ratio of density distribution of vascular bundles with asumption that both are highly correlated. The data in this study proved that there are high Pearson’s corellation between the theoretical and the empirical result, and the paired t-student test also showed both are not significantly different; thus, this new method could be applied in very good result. There are 3 models applied in this study, namely linear, logarithm, and power. Power model is the best among others since its theoretical gives the nearest estimation to the empirical measurement.
