Judul: Performance of Agronomic Characters in the Sorghum (Sorghum bicolor (L.) Moench) F3 Population Resulting from the Soraya 3 x Kawali
Abstrak: THEODORUS LEONARDO PAGAWAK. Performance of Agronomic Characters in the Sorghum (Sorghum bicolor (L.) Moench) F3 Population Resulting from the Soraya 3 x Kawali Crossbreeding Supervised by DESTA WIRNAS. Sorghum is one of the cereal crops that produces carbohydrates and can be used as a substitute for staple food other than rice. The development of sorghum varieties is very important to increase productivity and yield. This study aims to compare the selection results based on the diversity of agronomic characters in the F3 sorghum population and its two parent varieties, Soraya 3 x Kawali. The research was conducted in West Bogor. The materials used were F3 sorghum seeds resulting from the Soraya 3 x Kawali crossbreeding and seeds of the two parent varieties. Based on the analysis of variance and heritability conducted on several tested characters, each population showed diverse results. Specifically, the analysis of the genetic coefficient of variation for each character showed results ranging from medium to high, indicating the potential for improvement through selection. Based on the selection differential values, the panicle diameter and panicle weight were 0.32 and 1.36, respectively. Keywords: Rice, character, growth, crossbreeding, Soraya, Sorghum.

Judul: Variability of Agronomic and Amylose  Content of F2 Population of Sorghum Derived from a Cross Pulut 3 × Kawali
Abstrak: Sorgum adalah tanaman pangan terpenting kelima di dunia dan dapat dimanfaatkan sebagai pakan dan bioenergi. Agar sorgum dapat diterima sebagai sorgum pangan, khususnya sebagai beras, maka perlu dilakukan perbaikan kadar amilosa melalui kegiatan pemuliaan tanaman, yaitu mengembangkan varietas sorgum dengan tipe heterowaxy. Tujuan penelitian ini untuk memperoleh informasi tentang keragaman genetik pada karakter agronomi dan kandungan amilosa pada generasi F2 sorgum Pulut 3 × Kawali. Penelitian dilaksanakan dari bulan Februari sampai Juni 2022 di Kebun Percobaan Cikarawang, Dramaga Bogor. Bahan genetik yang digunakan populasi F2 sorgum Pulut 3 × Kawali, 2 tetua dan 9 pembanding. Hasil penelitian menunjukkan nilai tengah karakter populasi F2 sorgum Pulut 3 × Kawali berbeda nyata terhadap kedua tetua. Hasil uji lanjut DMRT menunjukkan adanya perbedaan karakter antara genotipe pembanding dan tetua. Analisis kurtosis menunjukkan karakter dikendalikan oleh sedikit gen dan banyak gen serta analisis skewness menunjukkan karakter dikendalikan oleh tipe aksi gen dominan, aditif, epistasis komplementer dan espistasis duplikat. Analisis heritabilitas arti luas bervariasi dari rendah, sedang, tinggi. Hasil dari karakter kualitatif keberadaan amilosa pada pewarnaan biji menunjukkan bahwa hasil dikendalikan oleh satu pasang gen dominan., Sorghum is the fifth most important food crop in the world and it can be used as food, feed and bioenergy. To be accepted as food, especially as rice, it is necessary to improve the amylose content through plant breeding activities to develop sorghum varieties with heterowaxy types. The purpose of this study was to obtain information on genetic variation in agronomic characters and amylose content in F2 shorgum generation. The research was conducted from February to June 2022 at Cikarawang experimental field, Dramaga Bogor. The genetic materiasl used were F2 shorgum population Pulut 3 × Kawali, 2 parents, and 9 comparisons. The results showed that the mean value of the population character F2 shorgum Pulut 3 × Kawali was significantly different from the two parents. The results of the DMRT test showed differences between the comparison and parental genotypes. Kurtosis analysis indicates that the observed characters controlled by few and many genes. Meanwhile, skewness analysis showed that the characters were controlled by dominance, additive, and epistasis genes action. Heritability analysis was vary low to high. The presence amylose based on seed staining showed that character controlled by one pair of dominance genes.

Judul: Infeksi Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
