Judul: Potential yield analysis of groundnut in term of capacity and activity of source and sink
Abstrak: The research was conducted with the aim to get the source and sink character of groundnuts that affect yield and percentage of full pods. The study was conducted by performing two experiments. Twelve varieties released from the years 1950-2003 are used. The 12 varieties were planted on two planting seasons (2007 and 2010) in two different locations. The observations made include source and sink capacity and activities, sink strenght, harvest index and yield. In the second experiment eight varieties were used to observe the non-structural carbohydrates (TNC) (2007). Two varieties of groundnuts were used to observe the translocation of carbon by using carbon 13 (13C) (2009). Characters of source and sink that positively and directly influence pod yield/plant of groundnut were number of pod/plant, weight of 100 seed and number of gynophores at 70 DAP. Characters which positively and directly affects harvest index were stem and leaf dry weight at 42 DAP, seed yield/plant and the number of pod/plant. Source and sink characters directly and positively affects the percentage of full pods were number of pod/plant, weight of 100 seed and LAI 70 DAP. There is an indication that most of assimilate for pod filling was obtained from the photosynthetic activities during the pod filling. There were no differences between varieties with different growth patterns. There is also an indication that some varieties do remobilisation of assimilate during pod filling period. There are seven patterns of source and sink relationship in groundnut varieties, based on the source and sink characters. Based on the source and sink characters that influence pod poduction and quality, an ideotype of groundnut plant with high productivity and high filling percentage was contructed.

Abstrak: The research was aimed to indentify the growth characteristics that influence filling of the pod and productivity of the groundnut. This research was conducted at Leuwikopo Experimental Field, Departement of Agronomy and Horticulture, IPB, Dramaga, on February to June 2010. The method of this research was based on a completely block randomized design, consisted of one factor and three repetitions. The factor was eight varieties, namely Pelanduk, Sima, Gajah, Turangga, Panther, Anoa, Kelinci, and Kidang. The data was analyzed by using F test. If there was significantly difference then it would be followed by Duncan Multiple Range Test (DMRT). The result showed that varieties affect signifficantly to the total of leaves, branch, and peg, weight of leaves, branch, and peg, and lenghth of the plants in several weeks of observations. Each varieties has difference characteristics of gowth and production. Pelanduk had highest growth characteristics. Gajah was the fastest on pod filling. Panther had highest growth parameter and production variables. Anoa was not really good at growth characteristic and pod filling so the productivity was low. Kidang had high dry matters and good at pod fillling. Sima, Kelinci, and Turangga had high total pod, but not so good at pod filling.

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.
