Judul: Pertumbuhan Beberapa Genotipe Jarak Pagar (Jatropha curcas L.) di Tanah Masam
Abstrak: Indonesia have many acid lands, but their usefullness were still a bit because the nutrient content in acid land is low. Meanwhile, Jatropha is a plant which can grow on various types of lands (includes on marginal land) and has used as raw material for biodiesel. Therefore, the growth of Jatropha need to be study on acid land as an effort for developing Jatropha and usefullness of acid land in Indonesia. To initiate that effort, the research about growing various genotypes Jatropha in acid land was done. The objectives of this research was obtained a potential genotype-tolerant for acid land. The research was conducted at UPTD Technology Development Dryland Singabraja Village, Tenjo Subdistrict, Bogor, West Java, from November 2010 - August 2011. This research using Randomized Complete Design Group (RKLT) with one factor, ie genotype. The result showed that there were differences in growth between the genotypes Jatropha. Generally, there are five genotypes of Jatropha with the best growth in acid land (pH 5.0), ie Medan I-5-1, Dompu, IP-2P-3-4-1, Sulawesi, and Bima M.

Judul: Respon Morfologi dan Fisiologi Aksesi Jarak Pagar (Jatropha Curcas Linn) dalam Kondisi Cekaman Kekeringan di Pembibitan
Abstrak: Jatropha (Jatropha curcas Linn) is one of the popular raw material when it comes to biodiesel fuel producing. It is often to encounter the problem where the land that is available to plant these Jatropha is the one that is marginal, so that it is important to see the tolerance of these Jatropha accessions to drought. The experiment was conducted in one of the Green House in Cikabayan, Darmaga IPB while the chlorophyll test was conducted in Molecular Marker, Spectrophotometer, and UV-Vis laboratory that is owned by Agronomy and Horticulture Department, Faculty of Agricultural, Bogor Agricultural Institute. The Research was started in July 2011 and ended in March 2012. The experimental design that was used in this experiment is factorial randomized block design. The first factor that was observed is the tolerance to the drought that was done in three degree which was 30%, 55%, and 80% of soil water content in the experimental field capacity. The second factor that was observed were 10 Jathropa accessions which have been evaluated, they were IP-3M, Jatim 013, Jatim 045, NTT 065,NTT 080, NTB 019, NTB 047, NTB 116, Sulawesi 72 and Sulawesi 117. Based on the a and b chlorophyll test that have been conducted Jatim 045 accessions signify the best result of treatment (the highest tolerance to drought). While from the scoring test the highest tolerance to drought in between 35% and 80% soil water content is shown by the NTT 065 accessions and the highest tolerance to drought in between 55% and 80% soil water content is shown by the Jatim 045 and NTB 047 accessions. There is no interaction occurs to both of the factors that were tested.

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.
