Judul: Analysis of agronomic characters and isozyme of physic nut (Jatropha curcas L.) at wet climate
Abstrak: The research objective was to determine agronomic characters influencing productivity and genetic variability of several physic nuts in high rainfall area. The research used Completely Randomized Design with three replications of genotypes as follows IP-1A, IP-1M, IP-2P, Lombok Timur, Lombok Tengah, Sumbawa, and Bima genotypes. The direct or indirect effect of each characters was determined by path analysis. Analysis of isozyme experiment of the eight genotypes was also conducted. The experiment showed that the most productive physic nut in high rainfall area was the IP-2P genotype (558.33 kg/ha). The agronomic characters influencing the yield were number of secondary branches, number of productive branches, total leaves, number of inflorescence, number of fruits/plant, fruit weight, seed length, number of seeds/plant, dried seed weight, and weight of 100 seeds. Overall, the most important characters contributing to weight of dry seed per plant is the number of inflorescence (X7) and number of seed per plant (X12), as shown by their positive direct influence and correlation coefficient (P7y =0.51; r7y=0.98) and (P12y=1.10; r12y=0.99). It is concluded that the two characters can be used as the selection criteria for yield. Genetic variability based on qualitative characters was 0-14%, quantitative 17-81%, the isozyme analysis 2-25%, for combined qualitative characters with the isozyme was 1-13% and for combined qualitative characters, quantitative characters and isozyme was 6-33%.

Judul: Agronomic performance and seed oil content of physic nut (Jatropha curcas L.) in wet climate of Bogor
Abstrak: Performance of agronomic characters of physic nut was determined on several physic nut genotypes in high rainfall area of Bogor, West Java since January 2010 until September 2011. The research used completely randomized block design with single factor, i.e genotypes (IP-1A, IP-1M, IP-2P, Lombok Timur,Lombok Tengah, Lombok Barat, Sumbawa Besar and Bima) and three replicates. There were two stages of research. In the first stage (January 2010 – December 2010), the plants were without pruning since planting, while in the second stage (January 2011 – September 2011) the plants were pruned. Observation on the first stage showed that the most productive physic nut in high rainfall was the IP – 1A genotype (87.7 kg/ha), and observation on the second stage showed that the most productive physic nut after pruning in high rainfall was the IP – 2P genotype (1014.2 kg/ha). The characters influencing the yield were number of fruits/plant, fruit weight, and number of seeds/plant. The highest oil content (seed basis) was achieved by Lombok Tengah genotype (32.61 %) while on kernel basis it was 53.34 %.

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.
