Judul: Pengaruh Jarak Tanam dan Jumlah Bibit per Lubang terhadap Produksi dan Mutu Benih Padi (Oryza sativa L.) Varietas IPB 3S.
Abstrak: Salah satu inovasi teknologi budidaya padi adalah pengaturan jarak tanam dan jumlah bibit per lubang. Penggunaan jarak tanam yang lebih rapat memberikan populasi tanaman lebih banyak. Penggunaan bibit per lubang yang lebih sedikit akan mengurangi penggunaan benih dan lahan semai. Penelitian ini bertujuan mendapatkan kombinasi jarak tanam dan jumlah bibit dalam satu lubang terbaik terhadap hasil produksi dan mutu benih padi Varietas IPB 3S. Penelitian ini menggunakan rancangan kelompok lengkap teracak (RKLT) dengan 2 faktor. Faktor pertama adalah jarak tanam dengan tiga taraf yaitu, 20 cm x 20 cm, 20 cm x 40 cm x 10 cm, 30 cm x 15 cm dan faktor kedua adalah jumlah bibit per lubang dengan dua taraf, yaitu 3 bibit dan 5 bibit per lubang. Bibit yang digunakan berumur 14 hari. Semua kombinasi perlakuan jarak tanam dan jumlah bibit per lubang menghasilkan produksi dan mutu benih tinggi sesuai dengan deskripsi varietas. Namun jika dinilai dari aspek ekonomi penggunaan tiga bibit dengan jarak tanam 30 cm x 15 cm lebih efisien dibandingkan perlakuan jumlah bibit dan jarak tanam lainnya.

Judul: Pengaruh jarak tanam terhadap pertumbuhan dan produktivitas tanaman padi IPB 4S
Abstrak: This research was carried out in February to June 2014. Design of experiment is randomized complete block design with a spacing factor as a treatment and consists of 6 levels. The levels of spacing are tiles 15 cm x 15 cm, 22 cm x 22 cm, 30 cm x 30 cm, 50 cm x 50 cm and legowo spacing (2: 1) 40 cm x 25 cm x 15 cm and 50 cm x 30 cm x 15 cm. Each treatment was repeated 3 times and resulted 18 experimental units. The size of experimental plots is 5m x 5 m. The results indicate that the wide spacing of 50 cm x 50 cm resulted in the number of tillers and number of productive tillers more than the narrower spacing and legowo, but a spacing of 30 cm x 30 cm resulted in higher productivity than other spacing. In addition, a late blight pest and birds attack intensives during grain filling which may inferencesd the productivity of IPB 4S.

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.
