Judul: Quality improvement of degraded ultisol in Jasinga  by soil tillage and organic matter amandement.
Abstrak: The sustainability of intensively used soils such as the highly weathered Ultisols depends on organic matter conservation and in order to maintain soil quality and to assure the farming sustainability. Among the inexpensive efforts to improve the soil quality are through utilization of in situ organic matters, such as Mucuna sp., Felimingia sp, and plant residues that differ in quality (in terms of lignin, cellulose and nutrients contents).

Judul: Kualitas tanah pada sistem silvikultur tebang pilih tanam jalur(TPTJ) di areal kerja IUPHHK/HA PT. Sari Bumi Kusuma provinsi Kalimantan Tengah
Abstrak: Rapid forest exploitations can cause forest degradation, and eventually may cause the global climate change, because of that, the balance of the forest sustainability must be kept as well. The implementation of silviculture system called Selective Cutting and Strip Planting System is one of several forest harvesting method that consider the importance of forest sustainability. Practically, the system has never been tested to the last cycle. So, it is necessary to conduct some evaluation to the method to assure its sustainability. Estimation of soil quality is one of several ways to evaluate the effectiveness of silviculture implementation on a forest area, Since the soil is one of the major factor that influencing the growth of vegetations, then its quality can be used as an indication of conservation of forest productivity. In this research, the soil sampling was done in the forest area of PT. Sari Bumi Kusuma, on class of 1-9 years cultivation age, on May 22-31 2009. The sampling method being used is purposive sampling on the plot with size of 100 m x 100 m, selected purposively based on the same physical characteristic, in each class age on the intermediate block and planting strip to the depth of 0-20 cm and 20-40 cm. The sample is then analyzed with statistic method called ANOVA, to compare the mean value, and then the research data was scored based on Pamoengkas (2006). The result from scoring was then substituted into the formula developed by Pamoengkas (2006), and finally grouped into several categories developed by Pamoengkas (2006). The result of this research is the founding of two categories of soil quality value in the forest area of PT Sari Bumi Kusuma. One is Medium Category (1, 2, 4, 5, 8, and 9 years of cultivation age), and the other is Low Category (3, 6, and 7 years of cultivation age). Those differences might be due to unpredictable factors which have created non-uniform environment conditions of the research area, and those environment conditions have influenced the development of parameters which affecting the soil quality.

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.
