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: Uji stabilitas galur-galur padi gogo hasil kultur
Abstrak: The objective of this research was to study the adaptation and yield stability of upland rice lines obtained from anther culture. Ten lines of upland rice obtained from anther culture and two check varieties (Way Rarem and Batutegi) were evaluated for their potential yield in seven different locations in the rainy season 2010/2011 and 2011/2012. In each location, the design was Randomized Complete Block Design with four replications. The method of Francis & Kannenberg, Finlay & Wilkinson, Eberhart & Russel, and AMMI (Additive Main Effect Multiplicative Interaction) were used to analyze the adaptation and yield stability. WI-44 line achieved the highest yield average (4.88 ton ha-1), higher than Batutegi and not significantly different from Way Rarem and has the highest potential yield (10.28 ton ha-1) in Malang in the second season. IW-67 yielded an average of 4.53 ton ha-1, not significantly different from Batutegi and has potential yield (9.09 ton ha-1) in Malang in the second season. WI-44 line has a superior yield average in seven environment. WI-44, IW-67 and IW-56 lines have an ability to adapt in optimal environments. I5-10-1-1, GI-7 and O18-b-1 were adapted in the marginal environments with yield above the average of the genotype tested.

Judul: Studi Kasus: Patomorfologi Trakheobronkhitis Supurativa Pada Kucing (Felis Catus).
Abstrak: Trakheobronkhitis merupakan penyakit saluran respirasi yang sering terjadi pada hewan kecil, terutama anjing dan kucing. Penelitian berupa studi kasus ini bertujuan untuk mempelajari patomorfologi trakheobronkhitis supurativa pada kucing. Perubahan patologi anatomi berupa eksudat purulen pada lumen trakhea dan warna paru-paru yang tidak homogen, warna lebih gelap pada salah satu lobus, dan permukaan paru-paru lebih menonjol. Perubahan histopatologi berupa badan inklusi amfofilik-eosinofilik intranuklear yang dikelilingi oleh clear halo dan titik-titik kromatin ditepinya pada epitel kelenjar trakhea dan epitel bronkhiolus. Badan inklusi ini merupakan ciri dari FHV-1 dan adenovirus. Pada trakhea juga ditemukan koloni bakteri berbentuk coccobacillus sebagai infeksi sekunder. Bakteri tersebut diduga Bordetella sp. yang sering menginfeksi saluran respirasi kucing. Deskuamasi terjadi pada epitel trakhea dan bronkhiolus. Selain itu, ditemukan juga sel radang limfosit, makrofag, sel plasma, dan neutrofil. Pada paru-paru ditemukan lesio bronkhiolitis. Ditemukan juga bronkhopneumonia yang ditandai infiltrasi sel radang neutrofil dan sel nekrosis pada lumen bronkhiolus. Paru-paru juga mengalami emfisema dan edema pulmonum. Hiperemia dan hemoragi juga ditemukan pada kapiler paru-paru. Pada kasus ini, trakheobronkhitis supurativa diduga disebabkan oleh FHV-1, adenovirus, dan bakteri jenis Bordetella sp.
