The need for board materials is currently experiencing a very drastic increase as the population in the world increases, especially Indonesia. Increasing the demand for boards resulted in diminishing forest resources. One way to overcome this problem is the efficiency of using wood through the manufacture of waste boards from industry or other lignocellulosic materials into particle boards which are relatively inexpensive materials obtained without reducing their quality or quality. This research to determine the physical properties (moisture content, density, shrinkage and thickness development) of empty palm oil and galam sawdust (Melaleuca cajuputi Powell). The results of the test made by OPEFB waste board and sawdust of galam wood have a water content value ranging from 9.16 - 10.92%, the density ranges from 0.42 - 0.55 g / cm³, the thick development ranges from 7.74 - 37.47%, shrinkage ranges from 1.59 - 4.51%. Only the water content and density values that meet SNI 03-2105-2006 while in the thick development only treatment A, C, and D that meet SNI 03-2105 2006. The composition of raw materials has a significant effect on the treatment of density values and very significant effect on the treatment value the development of thick, ambush. The best artificial boards are artificial boards and the composition is 100% natural because the average yield meets SNI 03-2105-2006.

Iron wood (Eusideroxylon zwageri), bengkirai wood (Shorea laevifolia endert), and red meranti wood (Shorea leprosula) used as a basic material in the manufacture of a ship. The wood used is enters the class of wood that is strong and durable, so it can survive in water. The use of wood as the hull of the ship is often damaged by attacks by marine animals such as barnacles and sea worms. Barnacles attached to the bottom of the ship resulting in reduced ship speed, while the shipworm larvae would make holes in the wood and make it brittle. The goal in this study is to analyze the intensity of damage to Ironwood, bengkirai wood and red meranti wood from attacks by wood-destroying organisms to determine which type of wood is better for use in shipbuilding. The test method was conducted using SNI 01-7207-2006. The wood sample is formed 30 cm x 2.5 cm x 5 cm and the middle is made a hole with a diameter of 1.5 cm. The sample is connected with a cable rope with a distance of 5 cm using a pipe. The sample is tied to the pier pole at low tide. Wood tested included in the category of highly resistant to attack barnacle organisms with an intensity of attack on each Wood <7%. Meranti test wood samples exposed to sea worm attacks with intesitas attack 33.3% - 56.6%, so this type of wood is considered less resistant to attack.Kayu ulin (Eusideroxylon zwageri), kayu bengkirai (Shorea laevifolia endert), dan kayu meranti merah (Shorea leprosula) dimanfaatkan menjadi bahan dasar dalam pembuatan sebuah kapal. Kayu yang digunakan merupakan kayu yang masuk ke dalam kelas kayu yang kuat dan awet, sehingga mampu bertahan di air. Penggunaan kayu sebagai lambung kapal sering mengalami kerusakan akibat serangan binatang laut seperti teritip dan cacing laut. Teritip yang melekat pada bagian bawah kapal mengakibatkan kecepatan kapal berkurang, sedangkan larva cacing kapal akan membuat lubang pada kayu dan membuatnya rapuh. Tujuan dari penelitian ini adalah menganalisis intensitas kerusakan kayu ulin, kayu bengkirai dan kayu meranti merah dari serangan organisme perusak kayu untuk mengetahui jenis kayu yang lebih bagus untuk digunakan dalam pembuatan kapal. Metode pengujian dilakukan menggunakan SNI 01-7207-2006. Sampel kayu dibentuk 30 cm x 2,5 cm x 5 cm dan bagian tengah dibuat lubang dengan diameter sebesar 1,5 cm. Sampel dihubungkan dengan talu kabel dengan jarak 5 cm mengunakan pipa. Sampel diikat di dermaga dengan kondisi laut yang surut. Kayu yang diuji termasuk ke dalam kategori sangat tahan pada serangan organisme teritip dengan intensitas serangan pada setiap kayu <7%. Sampel kayu uji meranti terkena serangan cacing laut dengan intesitas serangan 33,3% - 56,6 %, sehingga jenis kayu ini dinilai kurang tahan pada serangan

Effect of Lamination Pattern of Tali Bamboo (Gigantochloa apus Kurz) Beam on Density, Delamination, And Rupture StrengthBamboo is a potential species as its price is relatively less expensive than wood logs while it also represents a fast growing plant and is easy to plant. In general bamboos in South Kalimantan have not been exploited optimally. Its utilization for construction purposes is very limited. This study aims to identify the effects of lamination pattern on the density, delamination and rupture impregnability (Modulus of Rupture, MoR) of laminated bamboo blocks, with the combinations of a (reed wall- reed wall), b (reed wall-husk), and c (husk- husk and reed wall-reed wall). The results showed that lamination patterns affected the density, delamination and rupture impregnability of the laminae produced. The average density (kg/cm3) is 0.5321, 0.6923, and 0.6746 for treatments a, b, and c respectively. Delamination percentage (%) is 6.55, 16.65, and 21.1, while the rupture impregnability level (kg/cm2) is 228.99, 152.09,and 171.97 for treatments a, b, and c respectively. Delamination percentage of less than 10% suggets that the laminae produced can be used for building construction. that It is concluded that lamination pattern of reed wall-reed wall gave the best performance of bamboo lamina with the average density of 0.5321 kg/cm3, the delamination percentage of 6.55% , and the rupture impregnability level of 228.99 kg/cm2.
