Judul: Kasus gagal jantung pada kuda oleh perlemakan miokardial
Abstrak: Studi kasus pada kuda yang mati mendadak setelah latihan lari dan sebelumnya tela diberi pakan. Pengamatan dari morfopatologinya ditemukan adanya penyakit teatosis miokardium kronis, kolesterol granuloma pada serebrum yang multiple, edema diffe serebrum, kongesti limpa, ginjal, hati dan paru-paru, nekrosa papillary ginjal dan kma tubular nephron, hemorrhagi mesenterium dan miokardium dan kista ovari yang multiple. Hasil temuan mengindikasikan bahwa kuda betina tersebut menderita episode kerusakan jantung kronis dan beresiko mengalami gagal jantung yang dipicu oleh factor Stress pelatihan. Keadaan ini memicu terjadinya syok, kolaps sirkulasi dan kehilangan kesadaran. Keberadaan kolesterol granuloma pada otak yang meningkatkan tekanan intrakranial akan lebih menimbulkan kondisi kekurangan darah dan oksigen pada otak.

Judul: Kajian Patologi Perforasi Esofagus Pada Kuda
Abstrak: Perforasi esofagus pada kuda adalah kejadian penyakit yang fatal dan dapat menyebabkan kematian. Kejadian perforasi dapat menyebabkan penyakit sistemik pada organ tubuh kuda. Tulisan ini merupakan kajian kasus patologi yang bertujuan mempelajari perubahan patologi anatomi (PA) organ tubuh akibat kejadian perforasi esofagus dan mempelajari efek yang terjadi pada kejadian perforasi esofagus. Seekor kuda berjenis Sandel Wood dinekropsi untuk mengetahui kejadian kasus penyebab kematian. Perubahan PA diperlukan untuk menganalisa dan mengetahui kejadian dari kasus penyakit tersebut. Hasil penelitian menunjukkan terjadi perubahan dari keadaan umum luar berupa selulitis, myositis gangrenosa, pyothorax, pleuritis fibrinopurulen adhesif, laringitis hemoragis, trakheitis hemoragis, dan pleuropneumonia. Pada kuda ditemukan pula kardiomiopati, perikarditis fibrinosa, hemoperikardium, hipertrofi kordis ventrikel kiri jantung, endokarditis, ascites, perforasi esofagus, ptechie limpa dan spenitis, adanya pembengkakkan dan eksudat pada otak. Kejadian penyakit secara sistemik disebabkan oleh adanya bakteri yang masuk ke dalam rongga thoraks akibat antiperistaktik dari lambung yang masuk ke dalam rongga thoraks melalui perforasi esofagus. Bakteri menyebar secara sistemik melalui pembuluh darah dan menyebabkan kerusakan pada organ tubuh kuda., Esophageal perforation is a fatal disease that may caused death in horses. Perforation of esophagus causes systemic illness in the horse's organs. This study aims to investigate the pathological alterations in the anatomy brought on by esophageal perforation, as well as the effects that these alterations on the incidence of the condition. To ascertain the frequency of cases that led to the disease, a horse of the Sandel Wood breed underwent necropsy. The incidence of the disease case was evaluated by investigating at anatomy pathological changes. The findings revealed alterations in the general state of the skin, such as cellulitis, gangrenous myositis, pyothorax, fibrinopurulent adhesive pleurisy, hemorrhagic laryngitis, hemorrhagic tracheitis, and pleuropneumonia. Cardiomyopathy, fibrinous pericarditis, hemopericardium, left ventricular cardiac hypertrophy, endocarditis, ascites, esophageal perforation, splenic petechiae hemorrhage and splenitis, swelling (edema) and exudate in brain were also present in the horse. The presence of bacteria that entered to the thoracic cavity is a result of antiperistaltic from the stomach. Ingesta that entered the thoracic cavity through esophageal perforation caused the incidence of systemic disease. The bacteria harmed the horse's organs by dispersing throughout the blood vessels and producing septicaemia with ending by death.

Judul: Photosensor producing based on ferroelectric material of Ba0,5Sr0,5TiO3 doped by Ferrium Oxide (Fe2O3) on a P-Type Silicon Substate Si (100) applied as a digital camera with a single pixel image sensor
Abstrak: Thin film Ba0,5Sr0,5TiO3 (BST) doped with Fe2O3 was grown on p-type silicon substrate (100) using chemical solution deposition (CSD). It used the solvent 2-methoxyethanol with annealing temperature of 850°C and the doping treatment Fe2O3 of 2.5, 5, 7.5, 10 % of the mass formed BST. Pure BST had the highest absorption of 600 nm of light wavelength. Additions Fe2O3 moves highest absorption in the range of 560 nm. Fe2O3 addition was strengthening thin film sensitivity to the effects of light. In general, doping Fe2O3 10% was result the best absorbance and current-voltage of BST thin film. Electrical properties of thin films BST include dielectric, photoconductivity, and dissipation energy. Based on the current-voltage (I-V) analysis, pure BST and doped BST showed photodiode properties. Dielectric values obtained in the range from 23.32 to 243. Based on electrical conductivity data and energy dissipation, BST thin films have shown photodiode characteristics and are therefore suitable as light sensors. The image sensor in a digital camera is also a light sensor. This BST thin film has been scientifically proven to be a light sensor and also it can be applied as an image sensor. This is a novelty image sensor based on thin film Ba0.5Sr0.5TiO3.
