Judul: Keadaan Tegakan dan Petumbuhan Shorea spp. pada Areal Bekas Tebangan dengan Teknik Silvikultur Tebang Pilih Tanam Indonesia Intensif (Di Areal IUPHHK PT.Erna Djuliawati)
Abstrak: INTRODUCTION. Some introduced and implemented sylviculture systems in Indonesia are Clear Cutting with Natural Regeneration (THPA), Clear Cutting with Artificial Regeneration (THPB), Selective Cutting of Indonesia (TPI), Indonesia Selective Cutting with Planting (TPTI), Selective Cutting with Strip Planting (TPTJ), and The Intensive Indonesian Planting and Selective Cutting (TPTII). This research wants to know the effects of land slope level to Shorea spp. regeneration using The Intensive Indonesian Planting and Selective Cutting (TPTII) sylviculture technical, in view of both natural and artificial regeneration is very important to the forest stand sustainability on the next growth period. So, this research gives some informations to the company, on what slope level Shorea spp. can adapt and grow optimally. MATERIAL AND METHODS. This research was conducted on three different forest condition, i.e. primary forest, first year LOA TPTII (Et+1 forest), and second year LOA TPTII (Et+2 forest). This research used line transect sampling by 100 m x 100 m. In that plot, there are sub-plots, subplot of tree by 25 m x 20 m (22 m x 20 m after stripping), sub-plot of pole by 10 m x 10 m, subplot of sapling by 5 m x 5 m and sub-plot of seedling by 2 m x 2 m. Soil analyzed at Soil Fertilization and Chemical Laboratory, Soil Departement, Faculty of Agriculture IPB. Research equipments were map, phiband, haga hypsometer, brunton compass, pole, tally sheet, ropes, vegetation book, chopping knife, stationery, ring sample and paint. On those three different forests, the research was also conducted vegetation analysis, picking out of soil sample, mesuring height and diameter of seedling at the planting strip. And then regression analysis was conducted to know the relationship between plant growth and land slope. RESULT AND DISCUSSION. The result shows that in primary forest, the highest number of species was on middle slope level (15-25%), in the amount of 51 on tree rate. In first year LOA TPTII (Et+1 forest), the highest number of species was on steep slope level (>25%) in the amount of 62 on tree rate and in second year LOA TPTII (Et+2 forest), the highest number of species was on steep slope level (>25%), in the amount of 61 on sapling rate. Coefficients of the similar community that has a high average value of the similar community (>50%), on the flat slope level (0-15%) there were first year LOA TPTII (Et+1 forest) and second year LOA TPTII (Et+2 forest). On steep slope level (>25%), there were primary forest and first year LOA TPTII (Et+1 forest). At the same time, all communities on middle slope level (15-25%), has similarity value under 50%. The diversity of species in both primary forest and LOA TPTII shows that the value is more that 2.00. It means that the diversity in primary forest first year LOA TPTII (Et+1 forest), and second year LOA TPTII (Et+2 forest) was classified at middle to high. According to the data of regression analysis, both diameter and height of first year plant, the probability value of Shorea spp. diameter is 0.357 and the probability value of Shorea spp.

Abstrak: Application of intensive indonesian selective cutting and planting of silviculture system (TPTII) is expected to cause significant changes in the structure and composition of the stand. This relates to the diameter limit of trees felled and the commercial opening of 3 meter wide planting. This study aims to determine the changes in structure and composition of stands in TPTII system and to determine the value increment of plants planted Shorea parvifolia in line with TPTII Silviculture System. This research was held in IUPHHK Erna Djuliawati company area, Centre of Kalimantan which observed the vegetation succession in two different conditions of forest (LOA one and LOA two year). The analysis of vegetation was held with nested sampling technique on the two year forest after logging and striping (Et+2) at three of slope levels. diameter and height of retrieving data Shorea parvifolia plants growing on the path to know the value their increment. The results showed that the composition of the forest after logging has decreased at all levels of vegetation (seedlings, saplings, poles and trees). This is because the forest after harvesting is not fixed and a logged forest in 2006 and 2007. Shannon-Wiener species diversity (H ') in the LOA TPTII 2 (two) years ranged from 2.49 to 3.75 with a medium-high level of diversity. Stand structure on the LOA TPTII 2 (two) years are still indicating the characteristics of natural forest stand structure normal to the inverted J shape curve. Although the number of trees / ha decreased in each diameter class, but the availability of the tree is still quite pretty. Community Similarity Index (IS) between the primary forest with LOA TPTII 2 (two) only 58.03%, so it can be said to be the secondary succession process is still ongoing and not yet reached the climax stage. From the data on diameter growth of Shorea parvifolia can per year was 1.67 cm, while the high growth ranged from 175.32 cm per year. Having done a statistical test can be seen that the slope significantly affect the growth of seedlings in the LOA TPTII 2 (two) years.

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.
