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 objective of this research was to identify growth characteristic that affect the pods filling and production of eight varieties of groundnut. This research was conducted at the Lewikopo Experimental Farm, Darmaga, Bogor from February to July 2010 on Latosol soil. The varieties of groundnut in this experiment were Badak, Garuda3, Jerapah, Kancil, Mahesa, Singa, Tapir, and Trenggiling. Data analysis used the F test and if there was significant difference then followed by Duncan Multiple Range Test (DMRT). Correlation analysis between growth and production variables. The results showed that Mahesa variety had a good canopy during the growth but the number of pods and pods per plant dry weight were significantly lower that influenced low productivity. Garuda3 variety had a good canopy until pods formation phase. The number of pods per plant was significantly lower but good in pods filling and had a high percentage of full pods. Singa variety had a lush canopy during the growth but the pods dry weight was low because had a lot of the number of gynophorum and percentage cipo pods was high. Kancil variety had not noticeable growth of leaves, branches, and pods during growth. Productivity of pods and seeds were high, supported by the average number of full pods high so the percentage of full pods also high due to the long time of pods filling. Badak variety had a lush canopy during the growth and the number of pods and half full pods were significantly and the average number of full pods and cipo pods were high. Jerapah variety had not noticeable growth of leaves, branches, gynophorums, and pods during the growth and maximum growth rate at early flowering time until the pods formation phase. Jerapah variety less in shaping of pods and the number of pods and half full pods were significantly lower and the average number of pods cipo was lower. The canopy of Tapir variety increased during the growth and well in pods filling and had a high percentage of full pods. Trenggiling variety had the number of pods and half full pods were significantly lower but could produced high productivity of pods and seeds. Correlations between growth and production variables showed that the percentage of full pods affected by the gynophorum dry weight at pods formation phase and pods dry weight at toward harvest. Percentage of cipo pods affected by gynophorum dry weight and pods dry weight at toward harvest. Harvest index affected by the ILD during growth and CGR at towad harvest. Pods productivity affected by harvest index and seeds productivity affected by the percentage of full pods.

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.
