Judul: Development and Testing of Organic Container Seedlings for forest tree production of Gmelina (Gmelina arborea Roxb.) in the Nursery
Abstrak: Organic Container Seedlings (OCS) is a container seedling made from organic materials used for forest trees seedling production its easily decomposer. OCS have an advanlage compared to polybags and environmentally friendly. The objective of this study was to develop container seedling based organic matter materials for forest trees seedling stock production. This study used Completely Randomized Experimental Design with 2 factors experiment, namely raw material composition and natural adhesive. The observed seedling growth, seedling height, seedling diameter, variables top root ratio and plants biomass. The data obtained were analyzed with F test (Analysis of Variance), further test and with Duncan multiple range test. The result showed that the interaction between raw material composition and natural adhesive had highly significant effect on gmelina growth in the nursery. Raw material has highly significant effect on top root ratio and biomass plant. The raw material of news paper : compos 1:1 sive the best performance of seedling growth, and increased their height and diameter by 3.90% and 1.07% respectively, whereas the adhesive of tannin was better than tapioca., Wadah semai organik adalah wadah semai yang terbuat dari bahan organik yang digunakan untuk pembibitan yang mudah terurai. Wadah semai memiliki keuntungan dibandingkan dengan polybag dan ramah lingkungan. Tujuan dari penelitian ini adalah untuk membuat wadah semai berbahan dasar organik untuk persediaan pembibitan benih. Penelitian ini menggunakan Rancangan Percobaan Acak Lengkap dengan 2 faktor percobaan, yaitu komposisi bahan baku dan perekat alami. Pertumbuhan bibit yang diamati yaitu tinggi benih, diameter bibit, variabel rasio akar dan biomassa tanaman. Data yang diperoleh dianalisis dengan uji F (Analisis Varians), pengujian lebih lanjut dengan Uji Duncan. Hasil penelitian menunjukkan bahwa interaksi antara komposisi bahan baku dan perekat alami memiliki efek yang sangat signifikan terhadap pertumbuhan Gmelina (Gmelina arborea) di persemaian. Bahan baku memiliki efek yang sangat signifikan pada rasio akar dan biomassa tanaman. Bahan baku kertas Koran Kompos memberikan pertumbuhan terbaik untuk pertumbuhan benih, dan meningkatkan tinggi dan diameter berturut-turut sebesar 3,90% dan 1,07%, sedangkan perekat tanin lebih baik dari tapioka.

Judul: Pembuatan dan Pengujian Kontainer Semai Berbahan Organik pada Tanaman Sengon (Paraserianthes falcataria (L) Nielsen) di Rumah Kaca
Abstrak: Introduction. Organic Container Seedlings (OCS) is a container made from organic materials which serves as container seedling growth. OCS have advantages compared to polybags because in addition to functioning as a container seedling growth also environmentally friendly. This study tried to develop and test OCS added with natural tannin adhesive and tapioca their possibility for forest trees planting stock production in the green house. Materials and methods. This study used Completely Randomized Experimental design with 2 factors experiment, namely raw material composition and natural adhesive. The observed variables were shape and strength of container, seedling growth, seedling height, seed diameter, top root ratio and biomass plants. The data obtained were analyzed with F test (Analysis of Variance). If there was variable which showed significant difference between treatments, further test was performed with Duncan multiple range test. Results and Conclusions. According to results of Analysis of Variance, the interaction between raw material composition and natural adhesive had highly significant effect on sengon growth in greenhouse. Treatment given tannin adhesive has a best shape and strength of container with value indicators 96%. Factor of natural adhesive, raw material composition and interaction between them had highly significant effect on sengon growth. K3 treatment (Pulp+compos+tannin) has increase the sengon growth by 96,42% of the control. Tannin adhesives increase sengon growth by 33,42% of the control and composs media composition has increase the sengon growth by 31,96% of the control. The best adhesive is tannin which increase diameter growth by about 9,09% of the control. Factor of raw material composition has highly significant effect on top root ratio and biomass plant of sengon especially for m3 treatment (compos), it has 0,65 gram of biomass.

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.
