Judul: Agronomic Performance of IPB Promising Lines for Rice (Oryza sativa L.) Productivity Improvement.
Abstrak: Konsumsi beras yang tinggi dan semakin meningkatnya jumlah penduduk Indonesia menjadi tantangan upaya peningkatan produktivitas tanaman padi. Penelitian ini bertujuan membandingkan penampilan agronomi serta produktivitas padi galur harapan IPB. Penelitian dilakukan pada September 2022 hingga Januari 2023 di Kebun Percobaan Sawah Baru, IPB Dramaga, Bogor, Jawa Barat. Penelitian ini menggunakan rancangan kelompok lengkap teracak dengan lima perlakuan dan tiga ulangan. Perlakuan yang diuji berupa empat galur harapan IPB dan varietas IPB 3S yang ditanam menggunakan sistem jarwo 4:1. Galur padi yang digunakan yaitu AR18, FK22, H56, H88, dan varietas IPB 3S sebagai tanaman pembanding. Hasil penelitian menunjukan bahwa penampilan agronomi empat galur harapan IPB terhadap varietas IPB 3S tidak menunjukkan perbedaan tinggi tanaman, jumlah anakan, bobot kering tajuk, SPAD, luas daun bendera, laju fotosintesis, sudut kemiringan daun bendera, jumlah malai per rumpun, jumlah dan bobot gabah per rumpun, jumlah dan bobot gabah isi per rumpun, persentase gabah isi, dan bobot 1000 butir. Umur berbunga varietas IPB 3S lebih cepat dibandingkan AR18 dan FK22 dan tidak berbeda dengan H56 dan H88. Proyeksi produktivitas empat galur harapan IPB berkisar 7,92 - 11,24 ton/ha, tidak berbeda dengan IPB 3S (9,55 ton/ha). Galur H56 dapat diuji lanjut di lapangan karena menunjukkan keunggulan potensi hasil, bobot 1000 butir yang tinggi, ukuran daun bendera yang besar dan umur berbunga yang sama dengan IPB 3S., Increasing rice consumption as the consequence of the increasing population in Indonesia are a challenge for efforts to increase rice productivity. This research aims to compare the agronomic performance and productivity of IPB promising lines. The research was conducted from September 2022 to January 2023 at the Sawah Baru Experimental Field, IPB Dramaga, Bogor, West Java. This study used a completely randomized block design with five treatments and three replications. The treatments tested included four genotypes of IPB promising lines and IPB 3S planted using a 4:1 row ratio system. The rice genotypes used were AR18, FK22, H56, H88, and IPB 3S as a comparison variety. The results showed that the agronomic performance of four promising lines IPB compared to the IPB 3S variety showed no significant differences in plant height, number of tillers, shoot dry weight, SPAD, flag leaf area, photosynthetic rate, leaf angle, flag leaf leght, number of panicles per hill, number and weight of grains per hill, number and weight of filled grains per hill, percentage of filled grains, and 1000- grain weight. However, variations were observed in flowering time, with the IPB 3S variety flowering earlier than AR18 and FK22, however IPB 3S deading time showed no different with H56 and H88. The projected productivity of the four IPB promising lines ranged from 7.92 to 11.24 tons/ha, showed no different with IPB 3S (9,55 ton/ha). Line 56 could be recommended for further field trial since the line showed high potential yield, 1000 grains weight, a long flag leaf, and the same duration of heading time with IPB 3S.

Judul: Evaluation of 18 Improved Upland Rice Lines (Oryza sativa L.) of F9 Generation in Bogor Regency
Abstrak: Varietas unggul padi yang adaptif terhadap lahan kering merupakan salah satu teknologi dalam usaha meningkatkan produksi padi nasional. Kegiatan penelitian bertujuan untuk mengevaluasi keragaan produksi dan karakter agronomi lainnya dari galur yang diteliti sehingga memperoleh galur harapan padi gogo IPB generasi F9 yang memiliki potensi hasil tinggi dan karakter agronomi yang baik. Penelitian ini dilaksanakan di Kebun Percobaan IPB, Desa Babakan, Kecamatan Dramaga, Kabupaten Bogor, Jawa Barat. Penelitian dilaksanakan pada bulan November 2019 hingga bulan Maret 2020. Percobaan dilakukan dengan rancangan kelompok lengkap teracak (RKLT) faktor tunggal dengan tiga ulangan. Materi genetik yang dievaluasi terdiri dari 18 galur IPB dan 2 varietas pembanding yaitu varietas INPAGO 10 dan INPAGO 12. Hasil penelitian menunjukan bahwa galur yang diuji memiliki produktivitas yang setara dengan kedua varietas pembanding dan umur yang genjah. Galur IPB187-F-43-1-1, IPB187-F-66-2-2, IPB194-F-40-2-1, IPB194-F-78-2-2, dan IPB194-F-39-1-2 memiliki karakter agronomi yang lebih baik dari pada varietas pembanding. Karakter agronomi yang dimaksud antara lain bobot 1000 butir, panjang malai, umur panen, dan jumlah anakan. Galur IPB189-F-23-2-3 memiliki hasil gabah kering giling cukup tinggi yaitu 5,57 ton ha-1, sementara varietas INPAGO 10 berproduksi 4,27 ton ha-1 dan INPAGO 12 berproduksi 4,85 ton ha-1., Improved rice variety adaptive to dryland is one of the technologies suitable for increasing the national rice production. This study aimed to evaluate the yield and other agronomic characters of several IPB upland rice inbred lines and identify lines with good agronomic traits. This research was conducted at the Babakan Experimental Station of the IPB University, Dramaga District, Bogor Regency, West Java, from November 2019 to March 2020. The experiment used a single-factor randomized complete group design (RCBD) with three replications. The genetic materials evaluated consisted of 18 IPB rice lines and two check varieties, namely INPAGO 10 and INPAGO 12. The results showed that the IPB lines evaluated had equivalent productivity with the two check varieties and early maturity. The IPB187-F-43-1-1, IPB187-F-66-2-2, IPB194-F-40-2-1, IPB194-F-78-2-2, and IPB194-F-39-1-2 lines had better agronomic traits than the check varieties. These agronomic traits were grain size, panicle length, maturity, and number of tillers. IPB189-F-23-2-3 lines has a fairly high dry milled grain yield of 5,57 tons ha-1, while the INPAGO 10 variety is producing 4,27 tons ha-1 and INPAGO 12 is producing 4,85 tons ha-1.

Judul: Studi Kasus Patologi Hernia Diafragmatika pada Kucing
Abstrak: A cat was found with several critical conditions such as skin ulceration, exophthalmus, anorexia, cachexia, dyspnoe, anemia, constipation, and severe dehydration. The cat was well-treated with some medications but it failed. Radiographs show that diaphragm line was not seen with some abdominal contents displacement into the thoracic cavity. Necropsy study revealed many lesions in characteristic of congenital diaphragmatic hernia due to diaphragm anomalies. Histopathologically, congestion and other lesions were found in heart, lungs, liver, kidneys, spleen, lymph node, and brain. Those lesions were found due to negative pressure effect which moved the intestine and a part of liver into the thoracic cavity. Therefore, the heart and lungs could not work normal then consequence of the death was caused by congestive heart failure.
