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: Enhancement of photon absorbtion on BaxSr1-xTiO3 thin films semiconductor using photonic crystals.
Abstrak: In this research, has been conducted BaxSr1-xTiO3 (BST) thin films manufacturing for mole fraction x = 0.25, 0.35, 0.45, and 0.55; and concentration of 1 molar using chemical solution depositon (CSD) method. The materials, which are used in this research, are barium acetate [Ba(CH3COO)2, 99%], strontium acetate [Sr(CH3COO)2, 99%], titanium isopropoxide [Ti(C12O4H28), 97.999%], gallium trioxide [Ga2O3], 2-methoxyethanol [H3COOCH2CH2OH, 99%] and 1 x 1 cm of transparent conductive oxide (TCO) glass as substrate. Two BST thin films are made that for BST thin films which are doped by 10% galium (BGST) as p-type layer and pure BST solution as n-type. BST solution is made by reacting barium acetate [Ba(CH3COO)2, 99%], strontium acetate [Sr(CH3COO)2, 99%] and titanium isopropoxide [Ti(C12O4H28)] into 2-methoxyethanol solvent [H3COOCH2CH2OH, 99%] in accordance with mass gram for each x value. While, BGST solution is made in the same way as BST solution, plus adding gallium at 10% of the mass of BST. Once all materials are reacted, then vibrated using ultrasonic for 90 minutes, and followed by coating BGST / BST on the TCO substrate. Once the layer is formed, then annealed for 15 hours at temperature of 500 °C with increasing rate of 1.67 oC/minute. Characterizations of BST thin films with or without photonic crystals include the absorbance and transmittance in the visible light spectrum, as well as the electrical photoconductivity characterizations. From BST thin films without photonic crystals indicate that our thin films have light absorption area on almost the entire range of the visible light spectrum even to the infrared range with absorption value over than 67.6%, in addition, it can be seen that the maximum absorbance of BST thin films for all mole fractions lie in blue to green light spectrum region, 457 nm ≤ λ ≤ 570 nm and the minimum in yellow to red light spectrum region, 570 nm ≤ λ ≤ 678 nm. The largest absorbance is found at x = 0.25 with average absorbance value of 92.04% and maximum and minimum absorbance peaks at wavelength of 500.89 and 657.72 nm, respectively. At x = 0.35, average absorbance value decreased to 83.55% with maximum and minimum peaks at 505.73 and 613.68 nm, respectively. Then increased to 91.16% at x = 0.45 with maximum and minimum peaks at 506.04 and 618.56 nm, respectively. At x = 0.55, average absorbance value decreased to 80.12% with maximum and minimum peaks at 507.85 and 608.79 nm, respectively. Moreover, it can be seen that the addition of barium mole fraction leads to wider maximum absorbance or minimum transmittance peaks and narrower minimum absorbance or maximum transmittance peaks in the same range of the green and blue & red light spectrums, respectively. BST thin films with photonic crystals show increasing in absorption for all x values in the range of 3.04 into 13.33%. At x = 0.25, average absorbance percentage increased 3.96% from 92.4 into 95.68%, for x = 0.35 average percentage increased 7.07% into 89.45 from 83.55%. Furthermore, average absorbance of BST thin films at x = 0.45 increased 3.04% from 91.16 into 93.93% and x = 0.55 has
