Jabon (Neolamarkcia cadamba (Roxb) Bosser) is a fast growing and preferred species as material for various wood industries. However, the growth and quality information of its wood is still limited. This study aims to assess the characteristics of growth, physical properties of wood, genetic parameters of growth and physical properties of wood, and its relationship with pilodyn penetration on provenance-progeny trial of jabon in Parung Panjang, Bogor. Measurement of growth characteristics was performed on height and diameter at breadst height (DBH), whereas the physical properties of wood (density, specific gravity, and moisture content) were performed using core samples (destructive methods) and density estimation with pilodyn (nondestructive method). Statistical analysis explains that there are significant differences between provenances in height, diameter, pilodyn penetration, density, and specific gravity, except for moisture content. The mean of plant survival percentage of 36 months old jabon was 52.8%. The relationship between growth character and the physical properties of wood with pilodyn penetration is negative and weak, except in moisture content, positive but weak. The estimation of individual heritability value ranges from 0.011 to 0.183, while heritability of the family ranges from 0.017 to 0.308.Keywords: growth, heritability, jabon, physical properties, pilodyn penetration

Non-destructive testing based on sound wave propagation has been used widely to estimate wood quality of standing trees. The aim of this study was to evaluate the characteristics of the sound wave velocity in relation to pine resin productivity and resin intercellular frequency and diameter. The samples were 72 trees consisted of 36 trees which were tapped by the quarre method and 36 other trees were tapped with addition of stimulants. The speed of sound waves propagation was measured by SylvatestDuo for radial direction and longitudinal. The tapping position was determined refering to the wind direction. The resin productivity was twice for tapping with stimulant comparing to the control. The highest resin productivity was 87.31 g per harvest for tapping with stimulant and the lowest (39.86 g per harvest) for control. Statistically, there was not significant difference in sound speed for tapped position as well as for measurement before and after tapped of both radial and longitudinal testing, as well as for the anatomical properties of both of treatments. A high positive correlation was found between resin productivity and intercellular frequency for both treatments (r>0.80), however, there was not significance correlation between resin productivity and other parameters.Keywords: Pinus merkusii, resin tapping, sound wave propagation

Tracking the origin of Teak timber and its wood product is possible to be carried out using stable isotopes fingerprinting. To enrich the available variation patterns, Teak woods samples were collected from nine Forest Management Units (FMUs) representing all provinces and Teak centres in Java. Mills from all part of woods were mixed for analyses. The mills were burned under vacuum in a reactor system at 1200oC for 2 h, the resulting clean CO2 was transferred to the mass spectrometer to determine its isotopic composition of δ13C and δ18O. The generated data was then analysed using multivariate analysis. The results showed that isotopes analysis grouped Teak populations in Java intoWest Java population and mixed Central-East Java population. To consider wood as material for fingerprinting traded forest product, a refinement on method should be done.

Modifikasi Faktor Konversi Format dan Faktor Normalisasi Reliabilitas dalam Standar ASTM D 5457 untuk Penyempurnaan Standar SNI 7973:2013 (Modification of Format Conversion Factor and Reliability Normalization Factor in the ASTM D 5457 Standard Applicable for SNI 7973:2013 Standard) Leonard D D Liliefna; Naresworo Nugroho; Lina Karlinasari; Sucahyo Sadiyo

The Indonesian SNI 7973:2013 standard for wood design specification was an adopted standard from the USA national design specification (NDS) 2012. However, due to the climate differences between USA and Indonesia, the SNI 7973:2013 standard should be further modified in order to meet the climate condition in Indonesia. Format conversion factor (KF) and reliability normalization factor (KR) specified in the ASTM D 5457 standard contained the snow load for the duration of load factor. Therefore, the objectives of this study were (1) to replace snow load with occupancy live load to revise KF, (2) to use the revised KF and safety factors for softwood and hardwood to perform the reliability analysis on calculated resistance factors (fc), (3) calculate the new KR values using the revised fc. The result of FORM reliability analysis showed that there were, on the average, 15 and 26% increases of the calculated KR values, respectively, for softwood and hardwood, over the calculated KR values according to the ASTM D 5457 standard for each given coefficient of variation of material resistance distribution.

Thermally modified wood by heat treatment are conducted to improve wood quality through high temperature application dealing with to increase dimensional stability and biological durability. However, this treatment can decrease others properties such as mechanical properties and color changes. The aim of this study was to evaluate the color changes as well as hardness properties which undergone heat treatment. Sengon (Paraserianthes falcataria), jabon (Anthocephalus cadamba), and mangium (Acacia mangium) wood species were heat treated at temperature 120, 150, and 180 °C for duration 2 and 6 h. Pretreatments were carried through natural drying and kiln dryer at low temperature 40 °C. The result showed that the temperature and duration of heat treatment were effected on color changes to become darken mainly in jabon and mangium wood. Heat treatment at three temperature which subjected to the samples was not influenced significantly on hardness properties. Pretreatment maintained the moisture content stability but not influenced on wood properties tested.

The nondestructive testing using stress wave velocity method is known as most important tool to be used in quality control purposes. The aim of this study was to investigate the stress wave velocity (SWV) and to determine correlation between its velocity and dynamic MOE on static bending strength properties (MOE and MOR) of wood wool cement particleboards (WWCB). Thirty six WWCB particleboards from 3 tropical fast growing species (Paraserianthes falcataria, Maesopsis eminii, and Acacia mangium) and three different particleboards density of 0.5, 0.8 and 1.0 g cm-3 were made in this study. SWV value was determined using stress wave timer and it used to measure dynamic MOE. The measurement results of static bending strength method (MOEs and MOR) and by stress wave method were compared. The result showed the higher density of CBWW the higher of stress wave velocity. The WWCB particleboard of sengon possessed the highest value for both SWV and MOR. The dynamic MOE measured by stress wave method was about 80% higher than that static test. The good correlations were found between SWV and static MOE, MOR and it was statistically significant for linear regression model developed.Key words: fast growing species, nondestructive testing, static bending strength, stress wave velocity, wood wool cement particleboard

Cross Laminated Timber (CLT) is an engineered wood products composed of multi-layered panel of lumber where each layer of boards is placed cross-wise to adjacent layers. The purpose of the present research was to evaluate the compression strength perpendicular to grain of CLT composed of 5 layers tested with line loads in square surface. The position of line loads was in the centre and edge of sample orientated both in parallel and perpendicular to the grain direction at the CLT-surface. The CLT specimens were (15x20x20) cm3 (thickness, width and length) in size and were prepared from three community timber, i.e. sengon (Paraserianthes falcataria), mindi (Melia azedarach L.), and nangka (Artocarpus heterophyllus Lamk.). The result showed that the edge loading position resulted in lower compression strength than that of the central loading position. The highest comprresion strength was retained by CLT tested in the center loading position oriented to perpendicular to the grain direction. The highest compression strength perpendicular to grain was retained by CLT of nangka wood (20.28 kg cm-2) followed successively by those of CLT of mindi (25.97 kg cm-2) and CLT of sengon(8.50 kg cm-2).Keywords: CLT, compressive strength perpendicular to grain, line load, mindi, nangka, sengon
