Judul: Pengembangan bambu lapis berkualitas tinggi
Abstrak: Utilization of non wood forest product such as bamboo is one of alternative in reducing wood usage. Some advantages of bamboo among other are very fast growth rate, short rotation, high tensile strength, abundantly in many countries, and traditionaly has been using as building material. The aim of this study was to produce ply bamboo that has high quality in terms of physical and bonding strength properties, and also resistance to termite attack. The raw material used in this study consisted of three bamboos species, namely, tali (Gigantochloa apus), andong (Gigantochloa verticillata) and betung (Dendrocalamus asper); and five kinds of adhesives, namely methylen diphenyl isocyanate (MDI), phenol formaldehyde (PF), melamine formaldehyde (MF), urea formaldehyde (PF) and poly vinyl acetate (PVAc). Fundamental properties of ply bamboo tested according to SNI 01-5008.7-1999. This study consisted of two topics. The aim of first study was to improve mechanical properties of ply bamboo, especially in enhanching perpendicular to grain bonding strength, and the purpose of second study was to improve resistance of ply bamboo to termite attack. The treatments applied in first topic were glue taped and sewn of bamboo strands perpendicular to grain. The distances of each treatment applied in bambo strands of both glue taped and sewn were 5 cm, 10 cm, and 15 cm, respectively; whereas the treatments applied in second topic were soaking in cold water, hot water, and boiled lime solution 5 %. The results of first topic showed that MDI was the best adhesives for ply bamboo, in terms of improving physical and bonding strength properties significantly. The results also indicated that the treatments applied in ply bamboo improved physical and bonding strength properties significantly, especialy in enhancing the perpendicular to grain bonding strength. The results of second topics showed that boiled lime solution 5 % was the best treatments for ply bamboo in improving resistance to termite attack.

Abstrak: Wood production from forests is decreasing. In other side, the needs on wood as raw material for wood processing industries indicate an inclination to increase. As a consequence, wood supply is getting lower and the price of raw material is increasing. Hence, an effort is needed to produce alternative materials as wood substitution to ensure the sustainability of wood-based industries. The objective of this research was to analyze the influence of adhesive types, composition of width and thickness of bamboo’s strip to the physical and mechanical properties of ply bamboo. Bamboo was used in kajang bamboo mate type with different thickness of 0.5 mm and 1 mm, and different width of 1 cm and 2 cm. The internal bonding and modulus of elasticity (MOE) were not in accordance with SNI 01-5008.2-2000 with the values of less than 7 kg/cm2 dan 80 000 kg/cm2, respectively. Modulus of Rupture (MOR) and physical properties including moisture content and density fulfilled the SNI 01-5008.2-2000 standard which were less than 320 kg/cm2 for MOR and 14% for moisture content. Plybamboos in all combinations of width and thickness using epoxy were better than plybamboo which used PVAc as adhesive. The damage testing of ply bamboo using epoxy was 20.10%-35.58%. Plybamboo using thickness of 8 mm, width of 2 cm, and glued together with epoxy had better physical and mechanical properties compared with other plybamboos.

Judul: Infeksi Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
