<![CDATA[This paper presents study result on the log peeling properties and the glueing, physical and mechanical properties of the veneer and plywood made from nine wood species are described in this paper. The result shows that all of the, logs could be peeled in cold condition. The average veneer shrinkage from green to oven dry moisture content was 7.00 % and veneer swelling from oven dry to air dry condition the average value was 3.39 %. The average thickness reduction due to pressing in plywood manufacturing was 3. 78 mm. The bonging strength of plywood from 8 wood species (89 %) conforms with the Indonesian standard for type II, 9 wood species (100 %) with Japanese standard and 9 wood species (100 %) with German standard. The average specific gravity of multiplex was 0.61 while the average specific gravity of trplex was 0.60. Bending strength. tensile strength and compression strength parallel to grain of triplex are higher than multiplex.]]>

<![CDATA[Penelitian pembuatan bambu lapis dari batang bambu tali dengan ukuran besar telah dilaksanakan di pabrik kayu lapis. Ukuran nominal bambu lapis yang dibuat adalah 213,5 cm x 91,5 cm x 12 mm dengan perekat urea formaldehida cair. Untuk meningkatkan keawetan bambu lapis diberikan bahan pengawet ke dalam perekat urea formaldehida, yaitu CCB (chlor, chrom, boraks) dan boraks sebanyak 5% dari bagian berat urea formaldehida cair. Bambu lapis yang dibuat terdiri dari tiga lapis (tripleks) dengan macam lapisan pelupuh bambu semua dan yang lapisan luarnya pelupuh bambu sedangkan lapisan intinya venir meranti merah tebal 4 mm.Tujuan penelitian ini adalah untuk mengetahui pengaruh bahan pengawet dan pengaruh jenis lapisan bambu lapis terhadap sifat mekanisnya serta mengetahui rendemen pelupuh bambu dan bambu lapisnya. Hasilnya menunjukkan rendemen pelupuh bambu 67,62% (tebal4, 7 mm), dan rendemen bambu lapis 54, 45%. Kadar air, tebal dan kesikuan memenuhi StandarIndonesia, akan tetapi panjang dan lebar bambu lapis hanya 50% yang memenuhi syarat dan 33% tidak memenuhi persyaratan tersebut.Keteguhan lentur dan keteguhan rekat pada umumnya memenuhi Standar Jepang. Modulus patah bambu lapis dengan bahan pengawet CCB adalah yang paling rendah, sedangkan yang paling tinggi terdapat pada bambu lapis yang lapisan dalamnya venir. Dengan demikian bila yang diutamakan faktor kekuatan, maka dianjurkan membuat bambu lapis dengan lapisan dalam berupa venir tebal 4 mm.]]>

<![CDATA[Terak (slag) merupakan limbah peleburan baja pada pabrik baja. Selama ini pemanfaatan terak masih belum maksimal, sampai sekarang digunakan sebagai bahan pengerasan jalan di lingkungan pabrik. Guna meningkatkan pemanfaatan bahan terak tersebut salah satu caranya adalah sebagai bahan campuran perekat semen dalam pembuatan papan wol kayu.Papan wol kayu dibuat dari kayu tusam Pinus merkusii berukuran 30 x 30 x 2,5 cm Kadar terak yang dipergunakan ada 2 macam yaitu 33% dan 100% dari berat semen. Perlakuan perendaman wol kayu tusam di dalam air dingin ada 2 macam yaitu selarna 24 jam dan 48 jam.Kerapatan papan wol kayu tusam tidak memenuhi syarat Standar Jerman. Sifat mekanis berupa pengurangan tebal dan keteguhan lentur papan wol kayu tusam hanya pada perlakuan kadar terak 33% dan wol kayu direndam selarna 48 jam yang memenuhi syarat Standar Jerman.Secara ekonomi penambahan terak sebanyak 33% dari semen dan perendaman wol kayu selarna 48 jam belum tentu dapat menurunkan biaya pembuatan papan wol kayu.]]>

<![CDATA[Tanaman kelapa sawit (Elaeis guinensis) ditanam orang guna diambil minyaknya dari buahnya sebagai produk utama. Setelah berumur 25 tahun tanaman kelapa sawit ditebang habis, disebabkan minyak yang dihasilkan dari buahnya sudah tidak ekonomis lagi. Untuk meningkatkan pemanfaatan batang kelapa sawit, salah satu alternatif adalah dibuat sebagai bahan baku papan semen.Papan semen dibuat dari batang kelapa sawit dengan perekat semen dan berukuran 30 x 30 x 2,5 cm. kadar perekat yang dipergunakan 2 macam yaitu 150% dan 200% terhadap berat ekselsior kering udara. Perlakuan perendaman ekselsior di dalam air dingin selama 24 jam dan 72 jam.Papan semen tersebut diuji sifat fisis dan mekanisnya menurut Standar Jerman (DIN 1101). sifat fisis dan mekanis tersebut adalah kadar air, kerapatan, penurunan tebal akibat tekanan 3 kg/cm2 dan keteguhan lentur.Tujuan penelitian adalah untuk mengetahui pengaruh perlakuan kadar semen dan lamanya perendaman wol kayu kelapa sawit terhadap sifat fisis mekanis papan semen. ,Hasil penelitian ini adalah sebagai berikut: nilai rata-rata kadar air 10,65%, kerapatan 0,47 g/cm3, penurunan tebal akibat tekanan 3 kg/cm2 10,55% dan keteguhan lentur 9,37 kg/cm2. Dibandingkan dengan standar DIN 1101 kadar air dan penurunan tebal akibat tekanan sebesar 3 kg/cm2 memenuhi standar Jerman. Akan tetapi hanya keteguhan lentur papan semen yang berasal dari perlakuan kadar semen 200% dan lamanya perendaman ekselsior di dalam air dingin selama 72 jam (16,29 kg/cm2) dapat tnemenuhi standar Jerman. Hasil sidik ragam menunjukkan pengaruh tunggal semen dan lamanya perendaman ekselsior di dalam air dingin berpengaruh sangat nyata pada sifat keteguhan lentur dan penurunan tebal akibat tekanan 3 kg/cm2.]]>

<![CDATA[Blockboards of six wood species of logging waste from Lampung as core strip material were manufactured in the laboratory, and their physical and mechanical properties were tested.The average value of moisture content, board density and strip density were 10.09%, 0.63 g/cm3 and 0.49 g/cm3, respectively. Bending strength parallel to the grain varied between 690.47 kg/cm2 (red meranti) and 1041.99 kg/cm2 (keruing). The bending strength perpendicular to the grain varied between 112.40 kglcm2 (Bima) and 319.90 kg/cm2 (Pulai), and bending strength parallel to the grain were significantly affected by wood species, but bending strength perpendicular to the grain were not. ]]>

<![CDATA[The experiment result of using sago waste for particleboard is reported in this paper. The experiment covers the process of making particleboard with several raw material compositions and testing their physical and mechanical properties. The particleboard is bonded with urea formaldehyde resin with the dimension of 30 cm x 30 cm x 1,5 cm,The results indicate that most of the physical properties of particleboard meet Indonesian or FAO standards, while many of mechanical properties do not meet those standards. Veneer lamination improves the bending strength and the addition of sago bark do not improve physical and mechanical properties of particleboard.]]>
