Judul: Pengembangan Produk Cross Laminated Timber Melalui Pemanfaatan Kayu Sengon (Falcataria moluccana (Miq.) Barneby & J. W. Grimes) Menggunakan Sambungan Paku
Abstrak: The availability of good quality and big diameter wood in the natural forest, recently keep decreasing. It makes consumer should turn into public forest to fulfill their needs. However, low quality wood from public forest can be modified into product creation for structural material with high quality, which is cross laminated timber (CLT). CLT is created by arranging 3 to 7 laminas are crossed and then glued and compressed hydraulically on the entire surface or can be nailed (Perkins and McCloskey 2010). One of CLT product modification is by doing of combination lamina thickness and orientation angle. This study was aimed to determine the effect of thickness and orientation angle lamina comnbinations to the cross laminated timber panel product of Sengon wood (Falcataria moluccana (Miq.) Barneby & J. W. Grimes) by using nail connection. The average of nail CLT panel density (0.37 g/cm3) larger than control board and adhesive CLT. The average of nail CLT panel moisture content (4.19%) lower than control board and higher than adhesive CLT and not far different from the average of Bogor moisture content ±15%. The volume shrinkage of nail CLT panel (5.07%) is lower than control board and adhesive CLT, but it‟s not far different. The average of volume swelling nail CLT panel (3.74%) lower than control board and adhesive CLT. The average of MOE nail CLT panel is only 20% from control board and only about 15% from adhesive CLT and MOR. Nail CLT nail panel is able to reach 82% from control board and about 78% from adhesive CLT. The MOR of nail CLT panel is good but MOE isn‟t better than adhesive CLT. The average of lateral force nail CLT panel, smaller than stated by PPKI 1961. The average of shear strength nail CLT panel is larger than adhesive CLT panel. CLT panel with laminas 1,67 cm is the most optimum panel according to all tests result

Judul: Karakteristik Cross Laminated Timber dari Kayu Sengon (Falcataria moluccana (Miq.) Barneby & J.W. Grimes) dan Mindi (Melia azedarach L) menggunakan Perekat Isosianat
Abstrak: Wood needs as raw material construction has been increased. The advance of wood engineering technology can develop product by the raw material from the fast growing species. CLT (Cross Laminated Timber) is wood engineered product manufactured by lumber panel layer was placed perpendicular to raise a rigidity and stability. The aim of this research is to determined wood influence to characteristic of mechanical and physical properties of CLT products of fast growing species especially mindi (Melia azedarach L) and sengon (Falcataria moluccana (Miq.) Barneby & J.W. Grimes). This research was conducted by the manufacturing of panel CLT and testing of physical properties (density, moisture contents, swelling, hot water delamination, and cold water delamination) and mechanical properties (bonding, racking stiffness, and racking strength). The results showed CLT-450 mindi panel was relative more forceful than CLT-450 sengon panel. Physical properties testing carried out density, moisture content, soaking cold water delamination, and hot water delamination of CLT-450 mindi panel is higher than the CLT-450 sengon panel. Shrinkage CLT-450 mindi panel lower than CLT-450 sengon panel, but swelling volume (CLT mindi) higher than CLT-450 sengon panel. The applications of isocyanate relative more resistant to soaking cold water delamination than soaking hot water delamination. Beside of the influence of density, the bonding strength value of CLT-450 mindi panel higher than CLT-450 sengon panel which was contribute to racking strength test. However, the influence of water content to stiffness of CLT-450 sengon panel inverse to higher than CLT- 450 mindi panels. TR 1 correction and TR 5 carried out CLT-450 sengon and mindi panel had greatest point on water displacement.

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.
