Abstract

Agricultural fibers are currently used as a substituted resource to wood-based products. One of agricultural fibers that has been developed and become a resource for panel products is coir (coconut fiber). The purpose of this study is to evaluate the quality of veneered composite board made of coir and recycled polyethylene (RPE). The target density of board samples was 0.7 g/cm3. The board construction type is core type composite board (three layers). Veneers from Meranti (Shorea sp.) were used as face and back layers and coir was in the core layer. RPE composition was 50% based on coir particle and veneers oven dry weights. Recycled plastics were placed in three layers, 30% on the face and back layers, and 70% in the core layer. The coir sizes were under 1 cm, 1 cm, 5 cm, 10 cm, and 10 cm up (along coir size). The composite board samples were tested by JIS A 5908 – 1994. Each parameter was measured in three replications. The research results obtained are as follows : (1) Veneered composite boards made of coir and RPE fulfill the JIS A 5908 standard in term of density, thickness swelling after 2 and 24 hours of water immersions, modulus of elasticity, modulus of rupture and internal bond, and (2) The coir size did not significantly affect the properties of composite board. Keywords: veneered composite board, coir size, recycled polyethylene

Abstract

The purposes of this research are to know the influence of woods specific gravity and nail diameter to reference design value in double shear timber connections with steel side plates nail on four species of Indonesian commercial wood according to various approximation analysis. Analysis is done to four values and it is compared with other research that has been done. This research result from testing which have done by Ziannita (2009) referred as approach of A; result of research of Sadiyo and Sriyanto (2009) and Mansur (2009) referred as approach of B; values referring at literature referred as approach of C and compressive-joint total load divided by nail amount and factor of safety referred as approach of D (Sadiyo and Sriyanto, 2009 and Mansur, 2009). Joint done by using four species of Indonesian commercial wood which is meranti merah (Shorea leprosula), mabang (Shorea pachyphylla), kempas (Koompassia malaccensis) and bangkirai (Shorea laevifolia). Nails that applied in this research are nail with diameter of 4.1 mm length of 10 cm, nail with diameter of 5.2 mm length of 12.5 cm and nail with diameter of 5.5 mm length of 15 cm. The calculation of this research is done according to National Design Specification for Wood Construction-2005. Analysis results indicate that wood specific gravity influence the strength of connection, excelsior wood specific gravity will produce high strength of connection also. This can be influenced by mechanical properties from wood such as maximum crushing strength. Bangkirai have higher specific gravity than three others wood but result approach of D shows that the connections assess reference design value which is lower compared with two other woods (kempas and mabang wood). Then, the bigger on nail diameter brings bigger strength of connection also, but this thing depends on the conditions from nail and quality of nail materials. Key words: compression loading, double shear connections, nail, reference design value, steel side plates.

Abstract

Space truss is a three dimensional structure, which can draw forces work on its member either tension or compression without torsion. Space truss is favorable to build a large, light and stiff structure, which are made from relatively short bars.  This research is a feasibility study of using bamboo as space truss members.  This study focuses on designing bamboo connection, that strong enough for both tension and compression.  According to the analysis done, bamboo culm with diameter 4 cm and 6 cm could be use to make space truss member for a simple 3m x 4 m canopy structure.  The critical point of failure was on shear, because the shear strength of bamboo observed was only 3.9kg/cm2.  Designing with uniform length members of one meter, it’s found that for bamboo of 4 cm and 6 cm in diameter, depth of shear area of 5 cm and 3 cm, respectively, are needed.   Keywords: bamboo connection, space truss member, tension, compression

Abstract

Mangium wood from the timber estate have been developed continuously in an effort to reach the fulfilling of wood fiber and construction material needs to replace role of timber from the natural forests which has been decreased. Timber connection requires a connector such as bolt that can distribute both the load of wood to wood and the compression or tensile stress through all the connections. Bearing slip is a connector that is inserted into a hole in the wood, which bears pressure and shear. Bolted connection is the most commonly used because it is easy to apply, even though it is less efficient due to the shear forces will be retained by the bolts and wood only on the cross-sectional area of the bolt. This research trying to find the equations of the sum of  bearing slip connector to the strength of double shear connection  which composed of 17 years old mangium. The connector was made from  different materials that consisted of the same mangium, compressed mangium, ironwood and steel. The bearing slip connector consisted of two forms (dowel and rectangular) and arranged on one until three pairs of connector. The size and placement of the double-shear component based on Anonymous (2002), each form of the sample was made in 4 replications and all of them have been tested using a 35-ton Baldwin UTM. The result showed that the rectangular steel bearing slip connector has the highest equation (y = 5322e0.329x ) meanwhile the lowest equation was the ironwood materials (y = 3164e0.405x ). All of equations give high correlations ( R2 between 0.743 to 0.947).  Bearing slip connector can improve the ability of the connection in load-bearing. Densified of mangium able to raise the connection system's ability however not significantly, both in strength and displacement. Ironwood connector are not well used as a retaining shear pin because of easy to split and significantly much below in capacity than mangium wood. Steel connector resulted the higher load-bearing significantly than mangium and ironwood. Dowel do not differ in terms of strength as compared with rectangle, and each additional number of connector producing an increase in load-bearing ability significantly. Observation on the displacement value shows that for the value which applied usually in Indonesia reach the strength ratio (SR) as 92.21% to the proportion limit and 44.91% to the maximum load. This value was in below position of the US standard  (24.17 and 11.77%) and of the Australian standard (51.46 and 25.06%) to the proportional limit and maximum load respectively. Displacement achievement at the proportional limit varies from 1.1 to 2.2 mm, so that the minimum requirement of 1.5 mm displacement is not fulfilled by some treatments, however all of the connection system have passed the 1 mm displacement.

Abstract

Removing the outer part of bamboo for manufacturing flat bamboo lamination has disadvantage on the density of the product. The purpose of this experiment was to investigate the fixation of compressed bamboo from curved cross-section slats. The compression of bamboo slats using densification technique was aimed for uniform density. Furthermore, steam treatments were conducted to fix the deformation. The compressed bamboo slats revealed that the density of the samples at the bottom parts increased from 0.40–0.56 g/cm3 to 0.89–1.05 g/cm3 after pressing with a compression level between 46.98–63.97%, while the samples in the middle parts increased from 0.70–0.83 g/cm3 to 1.02–1.18 g/cm3 with the compression level of 32.92–41.50%. These results were slightly higher than that of the upper parts, which was between 0.91–0.98 g/cm3. The recovery of set decreased and the weight loss increased with  increasing  temperature and steam treatment time. Fixation of compressive deformation could be achieved at 160°C within 60 minutes. The bottom parts of samples experienced a slightly greater weight loss compared to the middle parts, i.e. 8.38% and 7.49%, respectively. The anatomical structure of bamboo tended to deform during densification process. Furthermore, the steam treatments affected  the colour of densified bamboo which became darker. From this experiment, it can be concluded that the manufacture of laminated bamboo from bamboo slats can be uniformed in strength by equalizing the density at the bottom and middle with the upper parts through the densification technique. However, further research should be conducted to know the delamination and shear strength of the bamboo lamination.

Abstract

Abstrak. Glulam merupakan salah satu metoda mengatasi keterbatasan dimensi bahan dasar kayu yang tersedia. Dengan mempersiapkan lamina-lamina dan menyusunnya serta melakukan proses perekatan antar permukaan lamina dapat menghasilkan dimensi balok sesuai kebutuhan. Tujuan dari penelitian ini adalah mendapatkan nilai kekakuan dan kekuatan lentur maksimum balok glulam dengan ketebalan lamina yang berbeda serta membandingkannya terhadap balok utuh. Kekakuan dinyatakan dalam MOE (modulus of elastcity), dan kekuatan lentur maksimum dinyatakan dalam MOR (modulus of rupture). Penelitian ini menggunakan kayu Akasia (Acacia mangium) termasuk kayu dengan kerapatan menengah. Balok glulam dibagi menjadi 3 (tiga) kelompok ketebalan lamina, masing-masing 20 mm, 15 mm and 10 mm. Selain balok glulam disiapkan pula balok utuh. Penampang melintang balok glulam maupun balok utuh adalah 60 mm x 60 mm. Perekat yang digunakan adalah Polyurethane merupakan Water Based Polymer Isocyanate. Perekat terdiri dari dua bagian; begian pertama adalah PI 3100 sebagai cairan resin, dan H7 sebagai cairan pengeras. Berat labur perekat diaplikasikan sebesar 280 g/m2 pada kedua permukaan rekatan. Prosedur pengujian dilaboratorium dilakukan berdasarkan ASTM D143-05, Standard Test Methods for Small Clear Specimen of Wood. Hasil penelitian menunjukkan bahwa konfigurasi penampang melintang balok glulam mempengaruhi nilai MOE dan MOR-nya; semakin tipis ketebalan lamina mempunyai tendensi semakin tinggi MOE dan MOR-nya; nilai MOE dan MOR balok glulam tidak berbeda nyata dengan balok utuh, dan kedua nilai tersebut dipengaruhi oleh tipe kerusakan balok. Abstract. Glued Laminated Beam represents one method in overcoming limited dimension of available raw material of wood. By stacking sequence of several timber layers to be bonded with glue  perfectly, the dimension which was required could be obtained. The objectives of this research were to determine the stiffness and maximum bending strength of glued laminated beam (glulam) with different thickness of lamina; it was compared to solid beam. The stiffness was represented as MOE (modulus of elasticity), and maximum bending strength as MOR (modulus of rupture). This research used Acacia (Acacia mangium) as a medium density wood. Glulam beam was divided into 3 (three) groups based on the thickness of lamina, 20 mm, 15 mm and 10 mm respectively. Solid beam was also prepared besides glulam beam. The cross section of glulam and solid beam was 60 mm x 60 mm. The adhesive, Polyurethane was used as Water Based Polymer Isocyanate. It consisted of two parts; the first part of the adhesive was PI 3100 as a liquid resin, and H7 as a liquid hardener. The two parts were mixed in the ratio of 100:15 by weight. The glue spread of adhesive was applied 280 g/m2 in a double spread. The procedure of investigation in the laboratory was tested in accordance with ASTM D143-05, Standard Test Methods for Small Clear Specimen of Wood. The result showed that the cross section configuration of glulam beam influenced in the value of MOE and MOR; the lesser the thickness of lamina the higher MOE and MOR value tendency were; the MOE and MOR of glulam beam were not significant different with solid beam, and it were influenced by the type of failure.

Abstract

Abstrak. Anatomi bambu disusun oleh sel-sel yang heterogen. Komponen anatomi bambu yang memberikan sumbangan terbesar pada sifat mekanisnya adalah ikatan pembuluh, sehingga kerapatan ikatan pembuluh dapat digunakan sebagai variabel dasar untuk menganalisa sifat mekanis bambu. Kerapatan ikatan pembuluh bergradasi dari tepi hingga ke dalam bambu sehingga dapat diturunkan suatu fungsi linier ataupun non linier sebagai pendekatannya. Rasio modulus elastisitas (E) yang lazim digunakan pada metode transformed cross section, pada penelitian ini dicoba diganti dengan rasio ikatan pembuluh dengan asumsi bahwa keduanya adalah ekuivalen. Hasil penelitian memperlihatkan bahwa terdapat nilai korelasi Pearson yang tinggi antara hasil teoritis dan hasil empiris, sedangkan hasil uji t-student data berpasangan menunjukkan bahwa tidak ada perbedaan yang signifikan antara keduanya. Dengan demikian model transformasi yang diturunkan dapat digunakan untuk melakukan analisa layer system pada bilah bambu maupun bambu laminasi dengan hasil yang dapat dipertanggungjawabkan. Dari ketiga model transformasi terpilih (linier, logaritmik, dan power) model power adalah model yang terbaik karena menghasilkan nilai yang paling mendekati data empiriknya.Abstract. Bamboo anatomy 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 degrade from outer to inner in a regular manner which could be fitted by linear and nonlinear function. Ratio of modulus of Elasticity (E) which widely used in transformed cross section method for analyzing the layered system was substituted by ratio of density distribution of vascular bundles within assumption that both are highly correlated. The data in this study proved that there was high Pearson's correlation between the theoretical and empirical result, and the paired t-student test also showed both were not significantly different; thus the new method could be applied in very good result. There are three model applied in this study namely linear, logarithm, and power. Power model is the best among others since its theoretical results the nearest estimation to the empirical measurement.
