Judul: Keragaan Galur-galur Gandum (Triticum aestivum L.) di Dataran Rendah.
Abstrak: Gandum merupakan salah satu tanaman pangan serealia yang paling banyak diproduksi selain jagung dan padi. Gandum merupakan salah satu komoditas tanaman pangan sebagai sumber karbohidrat dan protein. Kebutuhan dan konsumsi gandum dalam negeri semakin meningkat setiap tahunnya. Budidaya gandum terbatas pada dataran tinggi akibat kondisi agroklimat yang tidak sesuai pada dataran rendah. Hal inilah yang menjadi alasan pemuliaan untuk mengembangkan varietas gandum yang beradaptasi dengan daerah dataran rendah. Penelitian ini bertujuan untuk memperoleh informasi keragaan dan daya hasil galur-galur gandum di dataran rendah. Penelitian dilaksanakan dari bulan Desember 2022 sampai Maret 2023 di Kebun Pusat Kajian Hortikultura Tropika Tajur 2. Pengamatan komponen hasil dilakukan di Laboratorium Pemuliaan Tanaman 2, Departemen Agronomi dan Hortikultura, IPB. Penelitian terdiri dari satu faktor yaitu genotipe (26 genotipe dan 4 varietas pembanding). Penanaman menggunakan rancangan kelompok lengkap teracak dengan tiga ulangan. Hasil penelitian menunjukkan adanya perbedaan yang nyata antara genotipe yang diuji. Genotipe CBF-7.CAMN171 memiliki umur berbunga dan umur panen yang lebih genjah, dan luas daun bendera yang lebih tinggi dari keempat varietas pembanding berdasarkan uji Beda Nyata Jujur (BNJ). Semua galur gandum memiliki jumlah biji bernas dan jumlah biji ubinan yang tidak berbeda nyata terhadap keempat varietas pembanding., Wheat is one of the most widely produced cereal food crops besides corn and rice. Wheat is one of the food crop commodities as a source of carbohydrates and protein. Domestic demand for and consumption of wheat is increasing every year. Wheat cultivation is limited to the highlands due to unsuitable agro-climatic conditions in the lowlands. This is the reason for breeding to develop wheat varieties adapted to lowland areas. This study aims to obtain information on the performance and yield of wheat lines in the lowlands. The research was conducted from December 2022 to March 2023 at the Center for Tropical Horticultural Studies Experimental Field 2, Tajur-Bogor. Observations of yield components were carried out at the Plant Breeding Laboratory 2, Department of Agronomy and Horticulture, IPB. The study consisted of one factor, namely genotype (26 genotypes and 4 control varieties). Planting using a randomized complete block design with three replications. The results showed that there were significant differences between the genotypes tested. The genotype CBF-7.CAMN171 had a earlier flowering and harvesting age, and higher flag leaf area than the four control varieties based on the Honestly Significance Diffirence (HSD) test. All wheat lines had the number of filled seeds and seed number per square meter which were not significantly different compare to the four control varieties.

Judul: Performance of Wheat (Triticum  aestivum L.) at Tropical Lowland Agroecosystem
Abstrak: Gandum (Triticum aestivum L.) merupakan bahan pokok produksi karbohidrat yang cocok sebagai pengganti beras di Indonesia karena gandum memiliki keunggulan dibandingkan dengan makanan lain, yaitu kandungan protein gandum lebih tinggi dibandingkan dengan padi dan jagung. Penanaman gandum di daerah dataran rendah kurang menguntungkan karena menurunkan potensi pertumbuhan dan daya hasil gandum tersebut. Pemuliaan gandum terus berkembang hingga saat ini untuk mencapai tujuan produksi gandum dengan hasil maksimal dan berkelanjutan di Indonesia. Penelitian bertujuan memperoleh informasi keragaan galur-galur gandum di agroekosistem dataran rendah tropika. Penelitian dilaksanakan pada bulan Februari sampai Juni 2024 di Kebun Percobaan Leuwikopo IPB dan Laboratorium Pemuliaan Tanaman, Departemen Agronomi dan Hortikultura. Penelitian menguji 14 genotipe gandum (10 galur uji dan 4 varietas pembanding yaitu Dewata, Guri-5, Guri-6, dan Selayar). Penelitian menggunakan rancangan kelompok lengkap teracak (RKLT) faktor tunggal dengan tiga ulangan sehingga terdapat 42 satuan percobaan. Hasil penelitian menunjukkan bahwa genotipe gandum berpengaruh nyata terhadap karakter luas daun bendera, umur berbunga, dan umur panen. Genotipe CBF7-63 memiliki luas daun bendera yang lebih tinggi dari genotipe CBF6-8(4) dan CBF7-115, sedangkan luas daun bendera galur-galur uji tidak berbeda nyata dengan varietas pembanding Selayar. Genotipe CBF7-63 memiliki umur berbunga yang berbeda nyata lebih lama dibandingkan dengan genotipe CBF6-8(4) dan pembanding Selayar. Umur panen pada galur uji dan pembanding tidak memiliki perbedaan yang nyata., Wheat (Triticum aestivum L.) is the main ingredient for carbohydrate, and it is suitable for rice substitute in Indonesia because it has advantages over other foods for its higher protein content than rice and corn. Planting wheat in lowland areas is less desirable because it reduces the growth and yield potential. Wheat breeding has been continuously developing up to this day to achieve the purpose of wheat production with maximum and sustainable yields in Indonesia. Research aims to obtain information on the performance of wheat lines in tropical lowland agroecosystems. The research was conducted on February to June 2024 at the Leuwikopo IPB Experimental Field and the Plant Breeding Laboratory, Department of Agronomy and Horticulture. Research evaluated 14 wheat genotypes (10 test lines and 4 comparison varieties, namely Dewata, Guri-5, Guri-6, and Selayar). Study used a single factor randomized complete block design (RCBD) with three replications, so there were 42 experimental units. The results showed that wheat genotype had a significant difference on flag leaf area, flowering time, and harvest time. The CBF7-63 genotype had a higher flag leaf area than the CBF6-8(4) and CBF7-115 genotypes, while the flag leaf area of the test lines was not significantly different from the comparison variety, Selayar. The CBF7-63 genotype has a significantly longer flowering period compared to the CBF6-8(4) genotype and the Selayar comparison. The harvest age of the evaluated lines and comparison varieties did not have a significant difference.

Judul: Studi Kasus Liver Neoplasia pada Anjing Shih Tzu
Abstrak: Liver neoplasia is the excessive and uncontrolled replication of hepatocytes that forms nodules visible in ultrasonography. The purpose of this study is to study and discuss the characteristic, diagnosis and treatment of liver neoplasm through the interpretation of ultrasonography and hematology in a Shih Tzu dog. Ultrasonography is conducted with a Chison Q8 ultrasound machine with a 5 to 7 MHz frequency convex probe on lateral recumbency. The blood cells, liver enzymes and nodules sizes were the main parameters in this study. The results in the period of three years from 2021 to 2023 were interpreted and supported with secondary data sources. The Shih Tzu dog is 14 years old in the year 2023 with a body weight of 5.21kg. No obvious clinical signs were observed during previous examinations. However, lethargy, vomiting and anorexia were recorded in its latest examination. Thrombocytosis, granulocytosis, high liver enzymes and hypoglycemia, which are some of the neoplastic clinical manifestations were also presented by this patient. Besides, liver neoplasm, spleen neoplasm and biliary sludge were the sonogram findings of this patient. The liver and spleen neoplasm was observed stable, while the biliary sludge volume fluctuated. The treatment strategy recorded is Ondansetron, Samylin®, Ornipural and Ursodeoxycholic acid.
