Judul: Potensi Populasi Gandum (Triticum aestivum) Putatif Mutan Generasi M4 untuk Toleransi terhadap Dataran Menengah Iklim Tropis Basah di Indonesia
Abstrak: Wheat is an important food world because of its many benefits. According to their home environment, wheat can be grown well in areas with low temperature and in Indonesia is only found on the plateau with limited area. Therefore wheat varieties that are tolerant to the mid- to low-latitude with higher temperatures needed to be created. Gamma-ray irradiation has been treated on four wheat introduced varieties, namely Basribey, Kasifbey, Oasis and Rabe. The fourth generation of putative mutant populations shows higher mean and variance compare with the wildtype on plant height, tiller number, panicle length and spikelet number, but not on seed weight. The Basribey putative mutant population has the highest mean for almost all of the characters than the other three populations. Characters with moderate to high broad sense heritability were number of tillers, flowering, harvesting, number of spike, percentage of empty florets, main panicle seed weight, tillers panicle seed weight and seed weight per plant.

Judul: Adaptation of wheat lines (Triticum aestivum l.) Tolerance high temperature and improved genetic variation through mutation induction using gamma-ray irradiation.
Abstrak: Characteritation of ten wheat introduced genotypes and two varieties of wheat in two seasons and elevations showed different responses tested at any observed agronomical characters. Agronomical and physiological characters with high heritability estimated value and wide genetic variability were plant height, spikelet number and flag leaf area. There were five traits that directly affected seed weight/plant namely number of seeds/spike, number of seeds/plant, chlorophyll a, chlorophyll b and total chlorophyll characters. Index genotype sensitivity to high temperatures vary greatly based on the character were observed, the yield character of OASIS/SKAUZ//4 * BCN Var-28 genotype had a medium tolerance in two seasons. The G-21 and LAJ tolerance can be selected based on weight of seeds/spike, chlorophyll b, and yield characters, while Oasis tolerance can be selected based on the length of spike and grain weight/plant (2010). Genotype Oasis, H-21, and LAJ, Basribey tolerance can be selected based on the weight of seeds/plant and seed weight/spike. The Interaction of genotype x season x elevation significantly affected plant height, days of flowering, number of spikelet, number of floret, seed weight/spike, seed filling rate, yield, flag leaf area, stomata density, chlorophyll b and the leaves greeness characters. There only the location x genotype interactions affected the harvest, percent floret sterile, the number of seeds/panicle, 1000 grain weight, number and weight malai/m2 seeds/plants. Two genotypes had higher yield than comparable varieties Selayar the Basribey (2.00 t.ha-1) and Alibey (2.13 t.ha-1) in both elevation and two seasons. The HP 1744 is a stable genotype (1.75 t.ha-1), H-21 (1.82 t.ha-1) and varieties Selayar (1.92 t.ha-1). The results showed that the orientation of dose dose> 400 gy cause seedling growth under stress and cause the sprouts do not contain chlorophyll. Dose of 300 gy field research led to the death of 50% of the population in the irradiated plants. Gamma ray irradiation at 300 gy dose did not show significant effect on all the characters in M1 plants. The genetic diversity of the population appears M2 of all strains were irradiated. The characters that unaffected by the season, but only by the location x genotype interactions were the harvest time, percent of hollow floret, the number of seeds/spike, 1000 grain weight, number of spike/m2 and seed weight/plant. Basribey (2.00 t.ha-1) and Alibey (2.13 t.ha-1) genotypes had higher yield than comparator varieties (Selayar) in both elevations and two seasons. The stable genotype were HP 1744 (1.75 t.ha -1), H-21 (1.82 t.ha-1) and Selayar (1.92 t.ha-1) varieties. The results of orientation dose showed that the > 400 gy dosage caused seedling growth experienced stress and the sprouts did not contain chlorophyll. Dose of 300 gy on field research led to the death of 50% of the irradiated plant population. Gamma ray irradiation with dose of 300 gy did not show significant effect on all the characters in M1 plants. The character with moderate to wide genetic variability was harvest time. The number of hollow floret had wide genetic variability excepting in M2 population derived from Selayar varieties. The form of M3 populations at >1000 m asl was better than < 400 m

Judul: Telaah Histopatologi Urolithiasis Pada Kucing
Abstrak: Urolithiasis adalah suatu keadaan dimana ditemukannya batu di dalam saluran urinaria. Batu tersebut dibentuk dalam pelvis ginjal dan bergerak turun sepanjang ureter kemudian masuk ke dalam vesika urinaria dan uretra. Penulisan ini bertujuan untuk mempelajari lebih dalam secara histopatologi tentang kasus kematian seekor kucing dengan urolithiasis yang dinekropsi di Laboratorium Patologi FKH-IPB. Pemeriksaan patologi anatomi menemukan adanya fokal atelektasis paru, dilatasi ventrikel kiri jantung, hidrothoraks, hidroasites, ginjal pueat dan batu-batu berbagai ukuran dengan diameter 0,1-0,5 em pada vesika urinaria yang berdarah. Pada pengamatan histopatologi menunjukkan pembendungan semua organ, nephritis interstitialis kronis disertai bentukan mikrokista dan endapan mineral pada lumen tubuli dan sistitis nekrotik disertai pendarahan yang meluas. Pemeriksaan pada organ paru-paru ditemukan lumen alveolus sebagian mengempis dan sebagian lagi meluas. Dinding alveol menebal akibat adanya akumulasi eritrosit. Sedikit koloni bakteri tampak dalam lumen usus, bercampur dengan epitel usus yang terlepas di ujung viii. Hati mengalami pembendungan, ruangan sinusoid tampak meluas. Beberapa megakariosit tampak di dalam pulpa merah yang menunjukkan adanya aktivitas hematopoetis. Organ jantung tidak menunjukkan adanya perubahan histopatologi yang spesifik.
