Judul: Application of Plant Growth Regulators and Cuttings  Media on the Success of Teak Cuttings (Tectona grandis L.f)
Abstrak: Penyediaan bibit yang berkualitas merupakan hal yang penting dalam kegiatan revegetasi. Produksi bibit dapat dilakukan sacara generatif dan vegetatif. Penelitian ini bertujuan menganalisis pengaruh aplikasi indole butyric acid (IBA) dan media setek terhadap keberhasilan setek pucuk jati. Bahan setek diambil dari kebun pangkas jati PT Solusi Bangun Indonesia. Setek jati diberi perlakuan dengan zat pengatur tumbuh IBA (0, 250, dan 500 ppm) dan media setek (tanah, pasir, dan pasir + arang sekam). Keberhasilan setek jati dilihat dari kemampuan bahan setek untuk bertunas dan berakar. Aplikasi IBA tidak berpengaruh nyata, sedangkan media setek berpengaruh nyata terhadap keberhasilan setek jati. Semakin tinggi konsentrasi IBA yang diaplikasikan pada setek jati, maka semakin lama periode kemunculan tunas, semakin sedikit jumlah akar yang terbentuk, dan semakin pendek panjang akar. Hal ini menandakan bahwa auksin endogen pada bahan setek jati sudah cukup tinggi. Media setek berupa tanah merupakan media yang terbaik untuk mendukung keberhasilan setek jati. Secara umum, keberhasilan setek jati dalam penelitian ini masih rendah (11%)., Providing quality seedlings is important in revegetation activities. Seedling production can be done generatively and vegetatively. This study aims to analyse the effect of indole butyric acid (IBA) application and cutting media on the success of teak shoot cuttings. The cuttings were taken from the teak pruning garden of PT Solusi Bangun Indonesia. Teak cuttings were treated with IBA growth regulator (0, 250, and 500 ppm) and cutting media (soil, sand, and sand + husk charcoal). The success of teak cuttings was seen from the ability of the cuttings material to sprout and root. The application of IBA had no significant effect, while the cutting media had a significant effect on the success of teak cuttings. The higher the concentration of IBA applied to teak cuttings, the longer the period of shoot emergence, the fewer the number of roots formed, and the shorter the root length. This indicates that the endogenous auxin in the teak cuttings material is already quite high. Soil is the best medium to support the success of teak cuttings. In general, the success of teak cuttings in this study was still low (11%).

Judul: Pengaruh Bahan Penahan Air Aquasorb Terhadap Pertumbuhan Jati
Abstrak: Introduction. Teak (Tectona grandis Linn.f) is one of the tree species which is widely cultivated in Java. In large scale teak plantation forest development, climate is one of the important factor influencing the success of planting. Tight schedule of planting and erratic weather condition constitute the constraint for achieving successful planting. One alternative for overcoming the constraint is by planting outside the rainy season. Planting outside the rainy season when the water supply is very limited, assisted by the use of aquasorb, has not been known, in terms of its success rate. The use of aquasorb for planting forestry planting stocks, particularly that of teak, has never been practiced in Indonesia. Therefore, there is a need for research to learn the extent that aquasorb effect could improve the survival percentage of teak planting stocks when they are planted outside the rainy season. Materials and method. The research was conducted from May 2008 through Agustus 2008, in the green house of Faculty of Forestry (IPB). The research consisted of three series of experiments. The experimental designs used were Block Randomized Design for Experiment 1, Factorial Completely Randomized Design for Experiment 2, and Completely Randomized Design for Experiment 3. In Experiment 1, there were 5 treatments with 3 replications, and each replication consisted of 4 planting stocks, so there were 60 experimental units. In Experiment 2, there were 2 factors, namely factors of leaf and aquasorb. Altogether, in Experiment 2, there were 16 treatments, and each treatment combination consisted of 3 replications. Each replication consisted of 3 planting stocks, so that altogether, there were 144 experimental units. In Experiment 3, there were 5 treatments with 3 replications, and each replication consisted of 3 planting stocks, so that altogether there were 45 experimental units. The observed variables were among other things, survival percentage; duration for reaching initial, intermediate and final wilting; percent of dry leaves, and percent of leaf shedding. Analysis of Variance was performed by using program of Minitab 14 and SAS for Duncan advanced test. Results and Conclusion. Results of Experiment 1 showed that the use of aquasorb with concentration of 600 ml, had the highest average of survival percentage (41.67 %) at 4 weeks after planting (WAP) as compared with control. In Experiment 2, application of aquasorb with concentration of 400 ml, accompanied with leaf cutting (reduction) by 70 % could increase the survival percentage of teak planting stocks, up to 100 %, and reduced the dry leaf percent to 54.91 % as compared with control. Leaf reduction by 70 and 90 % and the use of Aquasorb of 400 ml could prolong the duration to reach final wilting, up to 15 – 16 days. Results of Experiment 3 showed that application of aquasorb with different type, at the same concentration, had significant effect up to 5 WAP, and did not have significant effect at 6 WAP. The use of aquasorb of type A at concentration of 400 ml, exhibited higher percent of survival (67 %) as compared with the use of aquasorb of type B. Conclusion from this research was that

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.
