Judul: Pengelompokan beberapa isolat jamur tiram putih (Pleurotus spp.) berdasarkan sifat pertumbuhan dan perkembangan
Abstrak: Jamur tiram putih (Pleurotus spp.) merupakan jamur pangan yang berprospek ekonomi tinggi. Penelitian ini bertujuan mempelajari pengelompokan delapan isolat jamur tiram putih berdasarkan sifat pertumbuhan dan perkembangannya untuk koleksi sumberdaya genetik yang dapat dimanfaatkan pada program pemuliaan jamur tiram putih. Penelitian ini menggunakan delapan isolat jamur tiram putih yang berasal dari berbagai sumber. Masing-masing isolat ditumbuhkan pada 30 kantong plastik (17x35cm) yang berisi masing-masing 1000 g substrat produksi dengan bahan utama serbuk gergajian kayu sengon (Paraserianthes falcataria). Berdasarkan parameter pertumbuhan dan perkembangan, maka kedelapan isolat terbagi menjadi empat kelompok, yaitu kelompok kesatu beranggotakan isolat MTR, kelompok kedua beranggotakan isolat AMD, TBN, dan BNK, kelompok ketiga beranggotakan isolat USX dan BBR, serta kelompok keempat beranggotakan isolat CSR dan PGN. Analisis korelasi menunjukkan bahwa diameter terbesar pileus berkorelasi negatif terhadap jumlah pileus. Jumlah pileus dan jumlah panen berkorelasi positif terhadap bobot basah. Bobot basah berkorelasi positif terhadap efisiensi biologi. Masing-masing fase vegetatif dan fase reproduktif berkorelasi positif terhadap masa pertumbuhan dan perkembangan. Jumlah panen berkorelasi positif terhadap efisiensi biologi.

Judul: Seleksi Isolat Jamur Tiram Putih (Pleurotus spp.) Berdasarkan Sifat Pertumbuhan dan Perkembangan
Abstrak: The research objective is a selection of isolates of white oyster mushrooms (Pleurotus spp.) based on characters of growth and development for obtaining excellent isolate and they can be used for breeding program. The materials were consisted of seven isolates of white oyster mushrooms from several source is AMD, MTR, BBR, PGN, USX, BNK, TBN, and CSR isolates. The works consisted of isolate maintenance, seed production, planting, harvesting, observation, data collection, and data analysis using SPSS 10.01 application program. Based on research results, USX isolate had the highest biological efficiency, MTR isolate had the fastest reproduction phase, BBR isolate had the highest weight of fruit body, BNK isolate had the highest number of fruit body and AMD isolate had the shortest vegetative phase and the shortest period of growth and development. The isolate which accomplished the criterias of selection was AMD isolate because it had a short period of growth and development, high biological efficiency value, produced the highest number of fruit bodies, also had diameter of fruit body suitable to criterias of consumer.

Abstrak: The aim of this study was to learn the role of diagnostic imaging to define the diagnose of the upper gastrointestinal tract disorder of the Schnauzer. The information from the owner (anamneses) stated that the dog has been vomiting for a year, sometimes containing blood. There might also be a possibility that it had eaten a corpus alineum. This study case covered physical examination, hematology and blood chemical analysis, radiography, ultrasonography, and endoscopy performed. Physical examination showed weight loss and anorexia. Hematology and blood chemical analysis showed an increase in lymphocyte, haemoglobin (Hb), haemotocrit (Hct), ureum, creatinine, alanin aminotransferase (ALT), and alkaline phosphatase (ALP). Abdominal radiograph showed no abnormality in the abdominal organs. Abdominal ultrasonography showed a hyperechoic mass on the stomach mucosal surface. The mass forms an acoustic shadowing at the ventral. The acoustic shadowing in the stomach may be caused by an accumulation of gas or foreign object such as bone. Endoscopy showed that there was inconsistency of stomach mucosa surface, foamy bile fluid in the stomach, ulcers, and erosion of the stomach mucosal surface. Based on the endoscopy performed, the animal was clearly diagnosed with chronic gastritis accompanied by stomach ulcer and erosion.
