The objective of this study is to determine the effect of fiber direction arrangement and layer composition of hybrid bamboo laminate boards on the physical and mechanical properties. The raw material used was tali bamboo (Gigantochloa apus (J.A. & J.H. Schultes) Kurs) rope in the form of flat sheets (zephyr) and falcata veneer (Paraserianthes falcataria (L) Nielsen). Zephyr bamboo was arranged in three layers using water-based isocyanate polymer (WBPI) with a glue spread rate of 300 g/m2. There were variations in the substitution of the core layer with falcata veneers (hybrid) as much as two layers and using a glue spread rate of 170 g/m2. The laminated bamboo board was cold-pressed at a pressure of 22.2 kgf/cm2 for 1 h, and the physical and mechanical properties were evaluated. The results showed that the arrangement of the fiber direction significantly affected the dimensional stability, modulus of rupture, modulus of elasticity, shear strength, and screw withdrawal strength. However, the composition of the layers had no significant effect on the physical and mechanical properties. The bonding quality of bamboo laminate boards with WBPI was considered to be quite good, as shown by the absence of delamination in all test samples. The bamboo hybrid laminate board can be an alternative based on the physical and mechanical properties that can meet laminated board standards.

The purpose of this research is to determine the efficiency of impregnation usingphenol formaldehyde resin to enhance Falcataria wood’s stability and better mechanical properties. Impregnation process was carried out after moisture content stabilized at 12% on samples with a dimension of 20 mm × 20 mm × 300 mm at various concentrations and pressure time. Dimensional stability was evaluated by thickness swelling (TS) and anti-swelling efficiency (ASE) and the young’s modulus was conducted according to BS 573. The mechanical properties and dimensional stability of impregnated wood were evaluated. Dimensional stability and mechanical properties of Falcataria wood were successfully increased after impregnation. PF impregnation can improve the mechanical properties and the density from 0.26 g/cm³ to 0.30 g/cm³ even with only 10% of weight percent grain. Dimensional stability increases with increasing resin concentration and time pressure. The highest increase in mechanical properties was found at a higher concentration of PF. The penetration of PF into the wood’s cell darkens the color of impregnated wood.

Betung bamboo (Dendrocalamus asper) is used as a building and handicraft material in Indonesia; however, bamboo needs to be dried to increase its stability. This study aimed to evaluate the efficiency of drying bamboo using solar energy and different drying oven designs. The betung bamboo pieces were dried using a direct solar dryer (direct drying) and an indirect solar dryer (indirect drying) and then the decrease in levels that occurred based on the relative humidity (RH) and temperature values achieved in the two dryers were compared. The highest average temperature in the direct indirect drying oven compartment was 60.1 ± 13.1℃ with 19.9 ± 16.4% RH and 60.2 ± 11.9℃ with 19.5 ± 15.5% RH, respectively. The drying defect in indirect drying was lower than that in direct drying, and indirect drying had a 61.7% greater average water loss than direct drying with significant difference (95%, analysis of variance) based on water loss/compartment volume parameters. Thus, the solar drying oven can be used to air-dry bamboo (14%) for 7 d from an initial moisture content of 70%–80% in bamboo strips. The results of this research can be used for small-scale bamboo processing industries that have limited use of electrical energy with quite good results.

This study aims to analyze the effect of structural Person-Organization Fit and organizational justice on organizational commitment, job satisfaction, Organizational Citizenship Behavior and employee performance. This study is based on a quantitative approach by collecting data using a survey conducted on three SOE's companies in Indonesia that operate in Makassar City, namely Pelindo. Ltd (Port Company), PLN. Ltd (Electric Company) and Pertamina. Ltd (Oil and Gas Company), with a sample of 90 employees. The study population was all non-managerial permanent employees. Data analysis using Structural Equation Modeling. In structural relations, out of the nine direct tests, there were two insignificant relationships, and in all three hypotheses there was one not-supported hypothesis. When compared between person-organization Fit and Organizational Justice, it is found that organizational justice has a more critical role in building Human Resource performance compared to Person-Organization Fit, because organizational justice is better able to provide job satisfaction and make organizational commitment and OCB as a prerequisite for its formation to better Human Resources performance. With organizational justice, employees will feel more satisfied working, committed to the work and organization, and behaves as a supportive organizational citizen for the realization of the best performance for the interests of the organization going forward.

Falcataria moluccana is a widespread species that grows rapidly in Indonesia and produces timber used for carpentry. Nonetheless, this species is especially susceptible to gall rust disease. To find plants that can handle rust, a mix of breeding with progeny experiments and forest management methods, like arbuscular mycorrhiza (AM ), were used. The point of this study is to find out if adding AM changes how F. moluccana seedlings grow and how they react to gall rust disease, both those that have been improved and those that have not. We will also look at the response by calculating the area under disease progress curves (AUDP C) value for rust disease to grow in F. moluccana seedlings. The experimental design comprised four different treatments, including varying quantities of mycorrhizae, as well as four different seed sources. For the mycorrhizal inoculation experiments, there was a control group and three treatment groups. The treatment groups got 5, 10, and 15 g of mycorrhiza per polybag, respectively. The seeds used in this study were sourced from two unimproved families, namely Java and Solomon, as well as two genetically improved families, F63 and F77. This study revealed that mycorrhizal application affects the growth of F. moluccana seedlings and significantly reduces both disease incidence and severity. The application of mycorrhiza reduces the disease incidence and severity; the AUPD C value of seedlings with mycorrhiza added is four times lower than that of seedlings without mycorrhiza. The disease severity was highest for the unimproved Solomon seedlings, despite the fact that the source of seeds had little impact on the disease incidence. Meanwhile, the genetically improved seedlings demonstrated lower disease incidence and severity rates than seedlings without improvement, with an AUPD C value nearly half that of the unimproved seedling. In terms of diameter and height, F. mollucana seedlings derived from various seed sources were remarkably diverse, and seedlings with improvements grew much better than seedlings without improvements. This study shows how arbuscular mycorrhiza affects how well improved and unimproved F. moluccana seedlings deal with gall rust disease.

A long-term breeding program of cajuput (Melaleuca cajuputi subsp. cajuputi) in Indonesia has aimed to increase oil productivity and quality through imposing selection for oil yield and 1,8-cineole content. This study examined the realized genetic gain for the two key varia- bles of oil yield, oil concentration and leaf biomass. Data were collected from a trial based on seeds collected from two unimproved, and two improved sources with selection inten- sities (IS) of 1.1 (10% of trees selected) and > 2.5 (<1% of trees selected). The trial was laid- out in a randomized complete block design with five replications. It was measured at 10 years of age. The leaf oil concentration of the IS >2.5 seed source was significantly higher than for the other sources; a realized genetic gain ranging from 14% to 31%. However, although not significant, this seed source had the lowest leaf biomass. The correlation between gains in oil concentration and leaf biomass was weak and not significant (r ¼ 0.15); while the correlation between oil yield and leaf biomass was very strong and highly significant (r ¼ 0.96). These results highlight the importance of carefully incorporating leaf biomass as a selection criterion in cajuput breeding programs aimed at increasing oil yield.

Poster Session : PS 0309 ; Hematology : Monocytes, Chemoattractants for Monocytes (MCP-1 and IP-10) and Type I IFN in Infl uenza Virus Infection

Monocytes could be infected with infi uenza virus and induce rapid differentiation into myeloid dendritic cells (mDCs). Virus-induced mDCs secreted chemoattractants for monocytes (MCP-1 and IP-10). We aim to evaluate monocyte, chemoattractans for monocytes and IFNalpha in infi uenza virus H5N1 and H1 N1. Secondary data were evaluated from medical record of H5N1(n=10) and H1N1 ( n=8) who were hospitalized in Hasan Sadikin Hospital since 2005. MCP-1, IP-10 and IFNalpha were evaluated using secondary data from previous study by Jusuf H : A Comparison of cytokine level between infi uenza A (H5N1) with infi uenza A (pH1N1) Mann Whitney test was used for comparison between H5N1 and H1N1, survive and death subjects. The correlation between chemoattractans for monocytes (MCP-1 and IP-10), IFNalpha and monocyte count were calculated using Spearmann correlation test. Monocyte count was lower in H5N1 compare to H1N1 (90 (0-240) vs 139 (36-560)/mm3, p 0. 17). Monocyte count was higher in survive compare to death subjects (150 (0-560) vs 75 (36-240) /mm3, p 0. 09). The death subjects had signifi cantly higher MCP-1, IP10 and IFNaplha (2171. 5 (985- 10000) vs 674. 4 (450. 2-1209. 3) pg/ml, p 0. 03, 3186. 9 (2436, 2-3937. 6) vs 971. 4 (520, 7-2387. 4) pg/ml, p 0. 03 and 354. 0 (87-2499. 8) vs 18, 6 (1. 41-184) pg/ml, p 0. 003, respectively). There was strong and signifi cant negative correlation between monocytes count and MCP-1 ( R -0. 8, p 0. 042) and between monocytes count andIP-10 ( R -0. 8, p 0. 019). Monocyte count could be used to characterized the severity of infi uenza viral infection. The lower monocyte count correlate with the higher chemoattractant for monocytes produced by mDCs.

Effect of Vascular Bundles and Fiber Sheaths in Nodes and Internodes of Gigantochloa apus Bamboo Strips on Tensile Strength

Atmawi Darwis,Anne HADIYANE,Endah SULISTYAWATI,Ihak Sumardi 한국목재공학회 2023 목재공학 Vol.51 No.4

Bamboo culm is in the form of a tube/pipe, composed of internodes which are bounded by a partition/diaphragm (node). Anatomically, bamboo is composed of vascular bundles and parenchyma ground tissue. One of the constituents of vascular bundles is fibers that are grouped to form a fiber sheath. The anatomical structure of the nodes and internodes is thought to influence the strength of bamboo strips, including tensile strength. This study aimed to determine the characteristics of vascular bundles (distribution and fiber percentage) and their effects on the density and tensile strength of Gigantochloa apus bamboo strips with and without nodes. The bamboo culms were divided into three parts (outer, middle, and inner) along the radial direction. The results showed that the distribution of vascular bundles and percentage of fiber sheaths decreased significantly from the outer to the inner layer. This also had a significantly decreased density and tensile strength. Furthermore, the number of vascular bundles (in the transverse plane) was greater in the internodes than in the nodes. Anatomically, the orientation of the vascular bundles at irregular nodes is observed in the radial and tangential planes, where the direction is not only in the axial direction, but also in the radial and tangential directions. This caused the tensile strength of the G. apus bamboo strips to be lower at the nodes than at the internodes.
