Abstrak: Palm oil (Elaeis guineensis Jacq.) is one types of plants belonged to monocot plants. In general, the anatomical structure of the trunk is composed of vascular bundles and parenchyma as essentially network. Basically, both of these components affect the characteristics of the wood. Based on the function, vascular bundles serve as the supporting structure and the transport system, while the parenchyma is the food storage elements. In a cross-sectional trunk, uneven pattern of vascular bundles is generated which continuously decreases from the outer to the center of the stem so that it will directly affect the characteristics of the "wood". The purpose of this research are to find a mathematical model of the relationship between the distribution of vascular bundles with a characteristic "wood" oil palm trunks and use this model in the transformed cross section of laminated wood oil palm trunk. This study consists of four stages. The first stage of observation influences the distribution of vascular bundles in the direction of the horizontal/radial (outer to the center of the stem) and vertical/longitudinal (base to top) of oil palm trunks on the characteristics of the "wood" (density and mechanical properties). The second phase is laminated wood characteristics of oil palm trunk. The variables used in this phase is the height position "wood" on the oil palm trunk (2 m, 4 m, 6 m), glue rate (200 g m-2, 250 g m-2, 300 g m-2) and press time (1 hour, 2 hours, 3 hours). The third stage is the influence of the thickness of the oil palm lamina taken from the outer of the trunk of the characteristics of wood laminations. Lamina raw material used was taken from a height of 2 m, 4 m and 6 m with a thickness of 6 cm, 3 cm, 2 cm, and 1.5 cm. The glue rate of adhesive and press time used in this phase refers to the second stage. Dimensional cross-section is made of laminated wood 6 cm by 6 cm. This phase of research aims to analyze the influence of the thickness of the lamina of the laminate wood characteristics of oil palm trunk. The last stage of the research is to analyze the modulus of elasticity laminate of oil palm trunk with methods Transformed Cross Section (TCS) based on the distribution of vascular bundles obtained from the first and the third stage. The results showed that the distribution of vascular bundles can be assumed as a function of distance from the edge to the center of the stem and is expressed in non-linear regression equation (power). The characteristics of oil palm wood are influenced by the distribution of vascular bundles. In the horizontal direction, the greater the number of vascular bundles distribution, density and mechanical properties will be higher, while the vertical direction indicates the opposite phenomenon. This relationship can be modeled in a multiple linear regression equation are : y = 0.221 - 0.023x1 + 0.001x2; R2 = 82% (density), y = 11609 - 2517x1 + 132x2; R2 = 70% (MOE), y = 76.710 - 13.942x1 + 0.852x2; R2 =

Judul: Characteristic of Cross Laminated Lumber from Oil Palm Trunk Waste
Abstrak: Tanaman kelapa sawit memiliki umur produktif 25-30 tahun. Tanaman kelapa sawit yang sudah tidak produktif lagi akan ditebang dan batangnya selama ini hanya dibiarkan begitu saja di lahan perkebunan sehingga dapat menjadi sarang hama bagi tanaman kelapa sawit lainnya., Palm plants have a relatively short life span about 25-30 years old. Palm plants are no longer productive will be cut down and the trunk only left on the farm and can be source of disease for the other oil palm plants.

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.
