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: Karakter Reproduktif Gandum (Triticum aestivum L.) Toleran Suhu Tinggi di Dataran Tinggi dan Sedang
Abstrak: Wheat (T. aestivumL.) is a cereal crop and member of the family Gramineae originated from subtropic region. It is suggested that putrescine aplication may improve wheat growth in tropical environment indicating that wheat crop might be resistant to high temperature stress and also able to increase its production. This study aimed to observe the effect of putrescine treatment to the reproductive characters of three cultivated varieties of high temperature-tolerant wheat that were plantedin Cisarua 600 m asl and Cipanas 1100 m asl, West Java. This experiment was designed as a factorial experiment with 2 factors. The first factor was putrescine with three consentrations 0, 1.25, and 2.5 mM. The second factor was wheat varieties, SBR, ASTREB and Nias. Wheat varieties influenced plant height and some reproductive characters including flowering and harvesting age, panicle length, number of spikelet, number of floret, number of empty floret, and seed weight per panicle. Moreover, altitude affected the plant height and number of tillers, but it did not affect the reproductive characters. Reproductive characters did not respond to putrescien application. The three cultivated varieties are high temperature-tolerant, therefore the varieties can be grown in two planting location.

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.
