Abstrak: The aims of this research were to estimate the values of general combining ability, specific combining ability and heterosis in sweet corn using a half dialel mating design. There were 7 inbreds, 21 hybrids, and 2 checks varieties (Bonanza and SG 75) used in this research. This research was conducted in Leuwikopo experimental station Dramaga Bogor, from November 2014 to January 2015. The experimental design was a randomized complete block design with 3 replicates. General combining ability values were estimated by Griffing II method. Heterosis were calculated based on mid-parent and high-parent values. Inbred JM8-4-3-1- 15-14 has the highest general combining ability in sugar content and yield. Inbred JM14-4-10-10-13-15 has the high general combining ability in ear length and days to harvest. Inbred JM17-6-13-1-12 has highest general combining ability for ear height. Hybrid 17 X 14 has the highest specific combining ability for yield and ear length. High heterosis values for yield and ear length were found in hybrid 17X6 hybrid.

Judul: Evaluasi Daya Hasil Jagung Manis (Zea mays L. var. saccarata)
Abstrak: Research has been done is the yield evaluation of hybrid sweet corn (Zea mays L. var. saccharata) with the aim of testing the results of seven sweet corn. Hybrids in order to support the needs of hybrid corn seed. The research began in Cibeurem, Darmaga, Bogor in October 2011 to January 2012. Genotypes used were: 3 x 4B, 6 x 8, 6 x 4A, 6 x 3, 3 x 8, 3 x 4A, and 6 x 4B and four commercial varieties were Mutiara, Sweet Boy, Super Sweet Corn, and Talenta. The hypothesis of this research is the evaluation of sweet corn hybrids can be superior or equal to the commercial varieties that can be continued into the new varieties. Experimental design used was Randomized Complete Block Design with three replications. Data were analyzed using the F test and if significantly different be followed by Dunnet (α = 5%). The result of this research showed that skin cobs weight, skin cobs weight/plot, productivity, and harvest index from 6 x 3, 6 x 4A and 6 x 4B hybrids were not significantly different with the best commercial variety, Talenta. Hybrid of 3 x 4A, 3 x 4B, and 3 x 8 have skin cobs weight and harvest index which not significantly different with the best commercial variety, Talenta. Total soluble solids(°brix) of seven hybrid was not significantly with the best commercial variety, Talenta.

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.
