Judul: Relationship of morphological and physiological characters with yield and efforts to increase yield of various types of rice cultivars
Abstrak: The objective of the research was to study relationship between morphological and physiological traits with yield and its components and the cultivation effort to increase grain yield of various types of rice cultivars. Experiment was conducted at Muara Experimental Station, Indonesian Center for Rice Research, Bogor, and at Babakan Experiment Station, University Farm IPB, Bogor, from June 2010 until November 2011. The study consisted of 4 experiments. The first experiment was conducted from June until December 2010 to study morphological characters and agronomy of various types of rice cultivars. The results showed that the top three leaves of new plant type (NPT) were better than those of local varieties (LV), improved new varieties (INV), and hybrid varieties. NPT and hybrids showed erect leaf characteristics and LV had droopy leaf characteristics. The sink capacity in NPT and hybrids was larger than that of INV and LV, but filled grains percentage in the NPT were lower than that of INV and LV. The highest yield was achieved by B11143 line (6.93 tons dry grain ready to mill/ha). The second experiment was conducted from December 2010 until May 2011. The objective of the research was to determine relationship between physiological characteristics with yield and its components in improved rice varieties. The results showed that physiological characteristics of NPT and hybrids were better than LV and INV. The physiological characters of NPT were high in photosynthetic rate, crop growth rate (CGR), and net assimilation rate (NAR) which was maintaned until seed filling stage. The highest yield was achieved by B11143 line (7.32 tons dry grain ready to mill /ha). The higher grain yield was caused by difference in physiological characteristics. The CGR, NAR, chlorophyll, and sugar content were correlated with yield components and yield. The third experiment was conducted from July until November 2011, to study plant spacing to increase yield of various types of rice cultivars. The result showed that yield was enhanced and the best was achieved by plant spacing of 15 cm x 30 cm in Ciherang, Maro, and B11143, while Pandan Wangi was not influenced by plant spacing. The fourth experiment was conducted from May until October 2011, to study nitrogen management to increase yield of various types of rice cultivars. The result showed that increase in nitrogen fertilization increased yield of all varieties. In the N management study, the highest yield was achieved by Ciherang, B11143 and Maro varieties at 125 kg N/ha, while Pandan Wangi at 100 kg N/ha. There was a positive correlation between yield and nitrogen absorbtion and content. Maro varieties at 125 N/ha showed higher absorption and agronomy efficiency (87.9% and 31 kg grain/kg N respectively).

Judul: Multicanopy Cultivation of Four Rice Varieties with Jajar Legowo Planting Distances at KP Babakan Dramaga
Abstrak: Padi (Oryza sativa) merupakan salah satu tanaman pangan terpenting di Indonesia. Peningkatan konsumsi beras tidak sebanding dengan luas panen di Indonesia. Penelitian ini bertujuan mempelajari pengaruh sistem budidaya dan varietas terhadap peningkatan produksi padi di Kebun Percobaan Sawah Baru IPB, Babakan Dramaga. Penelitian ini menggunakan RKLT faktorial dengan dua faktor yaitu sistem budidaya (monokultur, multikanopi sisip 1, multikanopi sisip 2) dan varietas (INPARI 32, INPARI 33, INPARI 43, IPB 9G sebagai tanaman sisipan). Hasil penelitian menunjukkan bahwa terdapat interaksi kedua perlakuan yang berpengaruh pada tinggi tanaman saat berumur 8 MST, tinggi batang saat panen, sudut kemiringan daun bendera. Pengaruh tunggal sistem budidaya signifikan terhadap tinggi tanaman padi saat berumur 8 MST, jumlah anakan, panjang daun dan sudut kemiringan daun bendera, bobot kering tajuk dan bobot kering malai saat panen, jumlah malai per rumpun, jumlah gabah isi per malai, bobot gabah per rumpun. Pengaruh tunggal varietas signifikan terhadap tinggi tanaman, jumlah anakan, panjang daun dan sudut kemiringan daun bendera, bobot kering malai, panjang malai, jumlah gabah per malai, jumlah gabah isi per malai, bobot 1000 butir, dan bobot gabah per rumpun., Rice (Oryza sativa) is one of the most important food crops in Indonesia. The increase in rice consumption is not proportional to the harvested area in Indonesia. This study aims to study the effect of cultivation systems and varieties on increasing rice production in the Experimental Garden of Sawah Baru IPB, Babakan Dramaga. This study used a factorial RKLT with two factors, namely the cultivation system (monoculture, multi-canopy insertion 1, multi-canopy insertion 2) and varieties (INPARI 32, INPARI 33, INPARI 43, IPB 9G as insertion plant). The results showed that there was an interaction between the two treatments that affected plant height at 8 WAP, stem height at harvest, flag leaf tilt angle. The single effect of the cultivation system was significant on rice plant height at the age of 8 WAP, number of tillers, leaf length and angle of inclination of flag leaves, crown dry weight and panicle dry weight at harvest, number of panicles per clump, number of filled grain per panicle, grain weight per clump. The single varietal effect was significant on plant height, number of tillers, leaf length and angle of inclination of flag leaf, panicle dry weight, panicle length, number of grain per panicle, number of filled grain per panicle, 1000 grain weight, and grain weight per clump.

Judul: Distemper Pada Anjing
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.
