Judul: Performance Evaluation and Power Yield on  11 Hybrids Sweet Corn Genotypes (Zea mays saccharata. Sturt) Breeding Results of IPB University
Abstrak: Informasi keragaan dan daya hasil diperlukan dalam merakit varietas unggul baru. Penelitian ini bertujuan mengevaluasi keragaan dan daya hasil jagung manis hibrida harapan IPB. Penelitian dilakukan pada bulan Desember 2022 sampai Februari 2023 di Kebun Percobaan Leuwikopo, Dramaga, Bogor, Jawa Barat. Penelitian terdiri dari satu faktor yaitu genotipe sebanyak 13 genotipe jagung manis hibrida. Penanaman dilakukan menggunakan rancangan kelompok lengkap teracak dengan 3 ulangan dari 20 tanaman per satuan percobaan. Hasil menunjukkan bahwa terdapat perbedaan keragaan dan daya hasil antar genotipe jagung manis hibrida IPB dan varietas jagung manis pembanding. Genotipe berpengaruh sangat nyata terhadap semua karakter yang diamati, kecuali diameter batang dan anthesis silking interval. Genotipe SB.13B X SM.9.3A.1 dan SB.5.1B.3B X T.13.1.8 memiliki beberapa keunggulan pada karakter seperti produktivitas, bobot tongkol tanpa kelobot, dan anthesis silking interval yang setara atau lebih baik dari varietas pembanding. Kedua genotipe hibrida harapan IPB ini memiliki produktivitas berkisar 19,04-20,42 ton per hektar sedangkan varietas pembanding berkisar antara 21,06-23,71 ton per hektar. Bobot tongkol tanpa kelobot kedua genotipe IPB berkisar 257,33-261,85 gram sedangkan varietas pembanding berkisar antara 249,13-253,53 gram., Information about performance and power yield of sweet corn is needed in assembling new superior varieties. This research aims to evaluate the performance and power yield of the expected hybrid sweet corn from IPB. The research was conducted from December 2022 to February 2023 at the Leuwikopo Experimental Garden, Dramaga, Bogor, West Java. The research consisted of one factor, which was the genotypes of 13 hybrid sweet corn genotypes. Planting was done using a randomized complete group design with three repetitions where each experimental unit consists of 20 plants. The results showed that there were differences in performance and power yield among the genotype sweet corn hybrids of IPB and comparison sweet corn varieties. Genotype had a very significant effect on all the characters that observed, except stem diameter and anthesis silking interval. The SB.13B X SM.9.3A.1 genotypes and SB.5.1B.3B X T.13.1.8 genotypes had several advantages of characters such as productivity, ear weight without husk, and anthesis silking interval which were equal or better than the comparison varieties. Genotypes SB.13B X SM.9.3A.1 and SB.5.1B.3B X T.13.1.8 had productivity ranging from 19.04 to 20.42 tons per hectare while comparison varieties ranged from 21.06-23.71 tons per hectare. The ear weight without husk of genotypes SB.13B X SM.9.3A.1 and SB.5.1B.3B X T.13.1.8 ranged from 257.33 to 261.85 grams while comparison varieties ranged from 249.13-253.53 grams.

Judul: Evaluation of Agronomic Traits and Yield Potential of Maize Genotypes (Zea mays L.) in Sumenep, East Java
Abstrak: Maize is the second main food crop after rice grown by farmers in Indonesia. Maize production is currently used for food, feed, and industry. Nusa Tenggara and Madura are areas that use maize as the main source of carbohydrates. Due to high demand over years, superior maize varieties with high yield potential are needed. This study aimed to identify maize genotypes with good agronomic performance and high yield potential. The experiment was conducted at the Batang-Batang Laok Village, Batang-Batang District, Sumenep Regency, East Java from October 2020 to March 2021. The genotypes evaluated consisted of 23 F1 hybrids, four single cross hybrid varieties, two three-way cross hybrid varieties, two open-pollinated varieties, and three local varieties. The research was conducted using a single factor randomized complete block design (RCBD) with three replications. The results showed that the genotype effect was significant on germination percentage, days to anthesis and silking, anthesis silking interval, plant height, main ear height, stem diameter, fresh ear weight with husk, fresh ear weight without husk, dry ear weight without husk, days to harvest, fresh ear length, dry ear length, fresh ear diameter, dry ear diameter, number of grain rows (fresh and dry ears), number of grains per row (fresh and dry ears), ear weight, grain weight per ear, 1000-grain weight, grain moisture, and prediction of grain yield potential. Dry ear weight had a significant and positive correlation with fresh and dry ear length, dry ear diameter, and number of fresh and dry grain per row. B2 x Mr14A has a higher predicted grain yield potential than NK 6172, and is recommended for further evaluation.

Judul: Urolitiasis pada anjing
Abstrak: Urolitiasis adalah suatu penyakit dimana terjadi proses pengendapan batu pada traktus urinaria. Kalkuli yang paling banyak dijumpai pada kasus urolitiasis anjing adalah kalkuli magnesium amonium fosfat (struvite), jika dibandingkan dengan kalkuli oksalat, sistin dan urat (Osborne et al., 1982). Infeksi oleh Staphylococcus aureus pada traktus urinaria memgang peranan penting dalam proses pembentukan kalkuli, karena bakteri tersebut dapat menghasilkan enzim urease, raktor predisposisi tidak dapat dinisankan dari infeksi traktus urinaria. Pada anjing, tempat yang banyak didapati pengandapan kalkuli adalah kantung air kemih dan uretra, sedangkan pada ginjalnya jarang. Pada anjing jantan lebih sering kejadiannya dibanding dengan pada anjing betina, karena anatomi traktus urinaria pada anjing jantan lebih memungkinkan untuk terjadinya obstruksi, yaitu lebih panjang dan sempit. Besarnya, kalkuli bervariasi, dari kecil dan halus seperti pasir sampai besar dan kasar seperti batu karang. ...
