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.

Judul: Effectiveness of Nutsedge (Cyperus rotundus L.) as Bioherbicide to Control Some Weed Species in Lowland Rice
Abstrak: Lahan tanaman padi di Indonesia yang luas masih belum bisa mencukupi kebutuhan pangan dalam negeri. Salah satu faktor penyebabnya adalah persaingan antara tanaman padi dan gulma. Inovasi yang dapat diterapkan dalam pengendalian gulma adalah aplikasi bioherbisida. Bioherbisida yang digunakan adalah bioherbisida dari senyawa alelopati yang dihasilkan tumbuhan. Senyawa alelopati dapat menekan bahkan mematikan tumbuhan lain di sekitarnya. Salah satu tumbuhan yang dapat dimanfaatkan untuk menjadi bahan baku bioherbisida adalah gulma teki (Cyperus rotundus L.). Penelitian ini bertujuan untuk mengetahui efektivitas bioherbisida berbahan baku teki pada lahan pertanaman padi sawah. Rancangan percobaan yang digunakan adalah rancangan kelompok lengkap teracak (RKLT) faktor tunggal dan tiga ulangan. Perlakuan terdiri dari kontrol (P0), pengendalian manual (P1), bioherbisida granul 22,5 kg tepung ha-1(P2), bioherbisida granul 45 kg tepung ha-1(P3), bioherbisida granul 67,5 kg tepung ha-1(P4), bioherbisida larutan 45 kg tepung ha-1(P5), herbisida pratumbuh Oksifluorfen 2 l ha-1(P6). Hasil percobaan menunjukan bahwa aplikasi bioherbisida teki formulasi granul dosis 67,5 kg ha-1dapat menekan pertumbuhan gulma Ludwigia octovalvis, Pistia stratiotes, dan Paspalum distichum dibandingkan dengan perlakuan tanpa penyiangan di lahan pertanaman padi. Aplikasi bioherbisida teki dapat meningkatkan hasil panen dan tidak menimbulkan fitotoksisitas terhadap tanamanpadi. Kata kunci : alelopati, bioherbisida, gulma, padi sawah, teki, Competition between weeds and rice is one of factors that decreasing rice productivity. An innovation that can be applied in weed control is the application of bioherbicides. The bioherbicide is usualy made of allelopathic compounds produced by plants. Allelopathic compounds can suppress some weeds. One of the plants that can be used as raw material for bioherbicides is nutsedge weed (Cyperus rotundus L.). The objective of the research was to determine the effectiveness of bioherbicide made from nutsedges (Cyperus rotundus L.) in rice fields. The experiment was designed as randomized complete block design with single factor and three replications. The treatments were without weeding (P0), manual weeding (P1), granule bioherbicide from nutsedge 22,5 kg ha-1(P2), 45 kg ha-1(P3), 67,5 kg ha-1(P4), solution bioherbicide 45 kg ha-1(P5), and Oxyfluorfen herbicide 2 l ha-1(P6). The results of the experiment showed that the application of bioherbicide with granule formulations at 67,5 kg ha-1could suppress the growth of Ludwigia octovalvis, Pistia stratiotes, and Paspalum distichum weeds compared to the without weeding treatment. The application of bioherbicide made from nutsedge could increase crop yields and did not cause fitotoxicity to rice plants. Keywords: allelopathy, bioherbicide, lowland rice, sedge, weed

Abstrak: Distemper merupakan penyakit infeksius pada bimbingan anjing yang menduduki tempet teratas dan penyakit ini tersebar di seluruh bagian dunia dimana terdapat anjing-anjing yang dipelihara, terutama pada anjing-anjing muda di kota-kota besar, pada kelompok-kelompok anjing atau pada situasi lain dimana banyak terdapat kontak antara anjing. Penyakit ini disebabkan oleh virus yang termasuk dalam famili Paramyxoviridae dan genus Morbilivirus. Infeksi virus ini sering disertai oleh infeksi sekunder oleh kuman Staphylococcus, streptococcus, Brucella bronchiseptica dan kuman Salmonella, inilah yang kadang-kadang sebagai penyebab kematian.
