Judul: Pengaruh Jarak Tanam dan Jenis Stek Terhadap Kecepatan Penutupan Arachis pintoi Krap. & Greg. Sebagai Biomulsa pada Pertanaman Tomat (Licopersicon esculentum M.)
Abstrak: This research was conducted in Cikabayan Experimental Field, Bogor from December 2011 to May 2012. The objective of this research was to study the effect of different types of cuttings and planting density of Arachis pintoi speed coverage and to find out the effect of the growth and the yield of tomato. The factorial experiment was arrangement in Randomized Completely Block Design with three replication. First factor was the types of cutting (bottom, middle, top) and the second factor was the density of planting (K1: 20 cm x 20 cm; K2:20 cm x 15 cm; K3: 20 cm x 10 cm; K4: 20 cm x 5 cm). The result of this research is that the density of planting and the cuttings factors were significant for increasing the coverage, but the interaction was not significant. K4 and K3 treatment are faster than K2 and K1 treatment on coverage speed. First and second factors were not significant for the growth effect and the yield of tomato. The coverage of Arachis pintoi can reduce the dry weight of weeds and able to increase the fruit weight per plant.

Judul: Pengaruh Jarak Tanam dan Konsentrasi Rootone-F terhadap Kecepatan Penutupan Arachis pintoi Krap. & Greg. pada Pertanaman Cabai (Capsicum annuum L.) Keriting Hibrida
Abstrak: This research was conducted on January until Agustus 2012 at Kebun Percobaan Cikabayan, Darmaga Bogor. Aim of this research is study about plant spacing on A. pintoi, dosage of Rootone - F, and interaction between both treatment to coverage of A. pintoi . Design of this research is Randomized Completely Block Design with 2 factors, plant spacing of A. pintoi (A1: 10 cm x 10 cm dan A2: 15 cm x 15 cm) and dosage of Rootone - F (B1: 0 ppm, B2: 200 ppm, B3: 400 ppm, B4: 600 ppm, dan B5: 800 ppm). Plant spacing A. pintoi in 10 cm x 10 cm has faster coverage than 15 cm x 15 cm. Until 45 days after plant A. pintoi, treatment with higher dosage of Rootone - F has higher coverage percentage. At 600 and 800 ppm dosage of Rootone - F give the best coverage percentage. A. pintoi can compete with weeds effectively at 90 days after plant when percentage of A. pintoi’s coverage higher than 80%. In this research, coverage of A. pintoi in 60 days after planting was critical periode when weeds compete with chilli in vegetative and generative phase. Plant spacing has influence to chili production. At A. pintoi 60 days after planting, plant spacing treatment 15 cm x 15 cm was better in compete and has higher chili production than 10 cm x 10 cm. Dosage of Rootone - F not influencing chili production. Dosage of Rootone - F has not influence to chili production. A. pintoi with higher coverage can compete with weeds especially broad leaf weeds and Cyperus sp.

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.
