Judul: Pemanfaatan Biomasa Teki (Cyperus rotundus L.) untuk Pengendalian Gulma Berdaun Lebar pada Pertanaman Kedelai (Glycine max (L.) Merr.).
Abstrak: Purple nutsedge (Cyperus rotundus L.) is one of weed species that has an allelopathyc potential. Supposed, this potency can give pressuring to broadleave weeds and cultivated plant growth, which is soybean (Glycine max (L.)Merr). This research took place at Cikabayan, University Farm IPB from Desember 2011 till March 2012. The purpose of this research is to know the influence of giving way of purple nutsedge toward broadleaves weed and soybean growth. The experiment used Randomized Complete Block Design with seven treatments. Fresh and dry purple nutsedge used as mulching, fresh and dry purple nutsedge used as organic material,purple nutsedge compost, and two control plots without purple nutsedge, free from weeds and unweeded. The dosage of purple nutsedge that used in this research was 6 ton/ha dry purple nutsedge for each plot with 20 m2 large. The result of vegetation analysis at 4 weeks after planted (MST) showed that purple nutsedge as a material organic treatment can pressure the growth of broadleave weeds, it was looked from sum dominancy ratio less than control plots, then followed purple nutsedge as mulching and purple nutsedge compost. On soybean vegetative growth, purple nutsedge treatment only significance to height at 2 MST. Beside that, purple nutsedge treatments give very significant influence to weight of pod per 4m2 plot. Fresh purple nutsedge as mulching has weighest than control plots and also other plot treatments.

Abstrak: Aplikasi bioherbisida berbasis umbi teki menjadi salah satu alternatif untuk mengurangi dampak persaingan gulma yang lebih ramah lingkungan. Penelitian ini bertujuan menguji keefektifan bioherbisida butiran berbasis umbi teki (Cyperus rotundus L.) 67,5 kg ha-1 dalam berbagai bentuk dan ukuran untuk mengendalikan gulma pada budidaya padi gogo serta pengaruhnya terhadap pertumbuhan padi gogo. Percobaan disusun menggunakan Rancangan Kelompok Lengkap Teracak (RKLT) faktor tunggal dengan dua belas perlakuan, yaitu: tanpa penyiangan (P0), penyiangan manual (P1), bioherbisida butiran bulat besar (P2), bioherbisida butiran bulat sedang (P3), bioherbisida butiran bulat kecil (P4), bioherbisida butiran bulat sangat kecil (P5), bioherbisida butiran silindris besar (P6), bioherbisida butiran silindris sedang (P7), bioherbisida butiran silindris kecil (P8), bioherbisida butiran silindris sangat kecil (P9), bioherbisida tepung 67,5 kg ha-1 (P10), herbisida sintetis Oksifluorfen 480 g ha-1 (P11). Hasil percobaan menunjukkan bahwa aplikasi bioherbisida butiran pada berbagai bentuk dan ukuran efektif menekan pertumbuhan gulma golongan daun lebar hingga 4 MSA. Aplikasi bioherbisida berbasis umbi teki tidak menimbulkan gejala fitotoksisitas terhadap pertumbuhan padi gogo. Aplikasi terbaik bioherbisida butiran pada perlakuan bioherbisida butiran sangat kecil baik bentuk bulat maupun silindris yang efektif menekan pertumbuhan gulma total dan gulma dominan Alternanthera sessilis dan Mimosa pudica, serta dapat meningkatkan pertumbuhan dan hasil padi gogo., The application of bioherbicide based from purple nutsedge can be one alternative to reduce the impact of weed competition that is more environmentally friendly This study aims to test the effectiveness of granular bioherbicide on nutsedge (Cyperus rotundus L.) 67.5 kg ha-1 in various shapes and sizes to control weeds in upland rice cultivation and its effect on upland rice growth. The experiment was designed using a random complete block design (RKLT) single factor with twelve treatments, namely: no weeding (P0), manual weeding (P1), large round granular bioherbicide (P2), medium round granular bioherbicide (P3), small round granular bioherbicide (P4), very small round granule bioherbicide (P5), large cylindrical granular bioherbicide (P6), medium cylindrical granular bioherbicide (P7), small cylindrical granular bioherbicide (P8), very small cylindrical granular bioherbicide (P9), powdery bioherbicide 67.5 kg ha-1 (P10), synthetic herbicide Oxifluorfen 480 g ha-1 (P11). The result of experiment that the application of granular bioherbicides in various forms and sizes effectively suppresses the growth of broadleaf weeds up to 4 weeks after treatment. The application of bioherbicide based from purple nutsedge didn’t cause phytotoxicity symptoms to upland rice growth. The best application of granular bioherbicide in the treatment of very small granular bioherbicide both round and cylindrical forms that effectively suppress total weed growth and dominant weeds Alternanthera sessilis and Mimosa pudica, and improving the growth and yield of upland rice.

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.
