Abstrak: Applications of shading modifes the amount of radiation reaching the plants. This study was aimed to determine the influence of shading by paranet 50% and 75% on leaf area index (LAI), solar radiation use efficiency (RUE) and production of red pepper. For the duration of filed experiment of 127 days, total global radiation above the plant canopy in open areas was 1778 MJ/m², above the plant canopy in the shading by paranet 50% was 1629 MJ/m² and above the plant canopy in the shading by 75% was 1364 MJ/m². In plants without shading, the maximum value of LAI was 3.18 and the minimum was 0.75, while the maximum RUE was 2.8 g/MJ and minimum RUE was 1.5 g / MJ. In shading by paranet 50%, the maximum LAI was 2.75 and minimum LAI was 0.64, maximum RUE was 2.7 g/MJ and minimum RUE was 1.4 g/MJ. In plants with shading by paranet 75%, the maximum value of LAI was 2.58 and the minimum was 0.60, while the maximum RUE was 2.6 g/MJ and minimum RUE was 1.3 g/MJ. Plants under shading by paranet 75% only produced 7% of the biomass of plants without shading.

Judul: Respon Tanaman Cabai Merah terhadap Arah Baris Tanam yang Berbeda
Abstrak: Seloka IPB is big red chili variety of a hybrid result between IPB C2 and IPB C5. This chili has harvest ageof 62 to 86 days after planting, has high productivity and is adaptedto lowland with an altitude of 100-250 masl. While Kopay chili variety is curly red chili from Payakumbuh, West Sumatra. Kopayhas harvest age of 80- 85 days after planting (in lowland) and 90-95 days after planting (in highland), has a high productivity, and has fruitslength of 30-35 cm. This research was aimed to analyze the effect of South-North (SN) and East-West (EW) row planting on radiation balance and on biomass production. The research was conducted from 23 February to 25 June 2014 in Climatological Station Class 1 BMKG Dramaga Bogor. The results showed that row planting direction significantly affected the number of leaves and total dry weight. Total global radiation above the plant canopy was 1712 MJ m-2. Interception of radiation in row direction of EW and NS amounted to 123.8 MJ m-2 and 132.7 MJ m-2, respectively. Radiation use efficiency (RUE) in row direction of NSwas between1.23 g/MJ (minimum) and 1.41 g/MJ (maximum); while in row direction of EWwas between 1.02 g / MJ (minimum) and 1.27 g/MJ (maximum). The row direction of NS was able to intercept radiation 7% larger than that of EW. In addition, the row direction of NSalso produced 24% more plant total biomass than the row direction of EW. It is concluded that planting inNSrow direction could utilize solar radiation more efficientlyand produce more biomass.

Judul: Urolitiasis pada anjing
Abstrak: Urolitiasis adalah suatu penyakit dimana terjadi proses pengendapan batu pada traktus urinaria. Kalkuli yang paling banyak dijumpai pada kasus urolitiasis anjing adalah kalkuli magnesium amonium fosfat (struvite), jika dibandingkan dengan kalkuli oksalat, sistin dan urat (Osborne et al., 1982). Infeksi oleh Staphylococcus aureus pada traktus urinaria memgang peranan penting dalam proses pembentukan kalkuli, karena bakteri tersebut dapat menghasilkan enzim urease, raktor predisposisi tidak dapat dinisankan dari infeksi traktus urinaria. Pada anjing, tempat yang banyak didapati pengandapan kalkuli adalah kantung air kemih dan uretra, sedangkan pada ginjalnya jarang. Pada anjing jantan lebih sering kejadiannya dibanding dengan pada anjing betina, karena anatomi traktus urinaria pada anjing jantan lebih memungkinkan untuk terjadinya obstruksi, yaitu lebih panjang dan sempit. Besarnya, kalkuli bervariasi, dari kecil dan halus seperti pasir sampai besar dan kasar seperti batu karang. ...
