Judul: Analysis of yield stability and performance of upland rice lines obtained from anther culture
Abstrak: The objectives of this research were to study the potential and yield stability of upland rice lines obtained from anther culture and their performance in the field. Ten upland rice doubled-haploid (DH) lines were tested for their potential yield in eight different locations (in Provinces of Lampung, West Java, Central Java, Yogyakarta, East Java - Indonesia) in the rainy season of 2010/2011 along with two check varieties (Way Rarem and Batutegi). In each location, the design was Randomized Complete Block Design with four replications. The results indicated that the line showing the most stable yield in different environment was I5-10-1-1 followed by WI-44, and IG-38. I5-10-1-1 produced 4.01 tons of dry grain per hectare. The line showing the highest yield was WI-44, and this line produced 4.72 tons of dry grain per hectare. Visualization with AMMI showed that IW-56 and IW-67 lines were specifically adapted in Purworejo, O18-b-1 was specifically adapted in Bogor, and IG-19 was specifically adapted in Malang.

Judul: Analysis of agronomic performance and stability of promising upland rice lines derived from buru rice landraces obtained through anther culture
Abstrak: The promising upland rice lines have been obtained from anther culture of crossing between released variety and Buru rice landraces. The lines need to be evaluated for their agronomic performance and yield stability at various locations. The objectives of the research were to obtain information of agronomic performance, yield stability and adaptability of upland rice lines at various locations. Ten upland rice lines and two check cultivars were evaluated at five locations (in Pekalongan - Lampung Province, Bogor and Sukabumi - West Java Province, Purworejo - Central Java Province and Malang - East Java Province) in the rainy season 2011/2012. In each location, the design was Randomized Complete Block Design with four replications. Four stability analysis methods were used to analyze the adaptation and yield stability of those lines (Francis- Kannenberg, Finlay-Wilkinson, Eberhart-Russel and AMMI). The results indicated that Fat-4-1-1, FM1R-1-3-1, FG1R-36-1-1 and FG1-6-1-2 lines produced the highest yield of dry grain per hectare (4.77; 4.54; 3.90 and 3.46 tons of dry grain per hectare, respectively). Fat-4-1-1, FM1R-1-3-1 and FG1R-36-1-1 lines have a potential agronomic and yield characters as new upland plant type of rice. Four lines were classified as stable by Francis-Kannenberg method, i.e FM1R-1-3-1, Fat-4-1-1, FG1-6-1-2 and FG1R-30-1-3. FG1-6-1-2 was the most stable genotype by Finlay-Wilkinson and Eberhart-Russel methods. Visualization with AMMI indicated that FG1R-30-1-3 was the most stable genotype across all locations.

Judul: Studi kasus skabies pada kucing di Rumah Sakit Hewan Jakarta periode Agustus 1997 - Juli 2000
Abstrak: Skabies pada kucing merupakan penyakit kulit yang disebabkan oleh infestasi tungau Sarcoptes scabiei atau Notoedres cati di dalam lapisan korneum kulit. Penyakit ini tergolong mudah untuk disembuhkan, terutama jika diagnosis pasti telah ditetapkan. Sejak Agustus 1997 sampai dengan Juli 2000 di Rumah Sakit Hewan Jakarta terdapat sebanyak 95 kasus skabies pada kucing dengan 80% diantaranya pada kucing yang memiliki rambut panjang, sedangkan 20% pada yang memiliki rambut pendek. Penderita skabies terbanyak berasal dari ras Persian (49,47%). Melalui metode pengobatan ivermectin (ivomec) dengan dosis 200 µg/kg berat badan secara subkutan, dilakukan dua minggu sekali, 77,89% penderita mengalami persembuhan, sedangkan sisanya (22,11%) berada dalam tahap persembuhan. Selanjutnya dari data tersebut dapat diketahui bahwa penderita dengan umur kurang atau sama dengan satu tahun memiliki tingkat persembuhan yang lebih baik daripada penderita dengan umur lebih dari satu tahun. Demikian pula halnya dengan kucing-kucing berambut panjang memiliki tingkat persembuhan yang lebih baik dibandingkan dengan yang berambut pendek.
