Judul: Studi Kasus: Morfopatologi Anjing Penderita Ehrlichiosis yang Disertai Sindrom Uremia
Abstrak: Ehrlichiosis adalah penyakit infeksius dengan morbiditas tinggi yang disebabkan oleh Ehrlichia canis pada anjing. Di sini menjelaskan tentang morfopatologi anjing jenis German Sheperd dan Labrador retrivier yang menderita Ehrlichiosis disertai uremia yang dating ke Divisi Patologi, Departemen Klinik, Reproduksi, dan Patologi, IPB University. Anjing ditemukan mati dengan perdarahan hebat di seluruh subkutis dan berbagai organ, edema subkutis di semua tungkai, jaringan lidah nekrotik, dan mukosa pucat. Studi kasus ini bertujuan untuk mengkaji perubahan patologi-anatomi dan histopatologi dari berbagai organ anjing sehingga diketahui perjalanan penyakit dan penyebab kematiannya. Sampel organ kedua ekor anjing meliputi jantung, paru-paru, lidah, lambung, usus, hati, limpa, dan ginjal dibuat preparat histopatologi dan diwarnai dengan pewarnaan Haematoksilin-Eosin. Hasil pemeriksaan patologi-anatomi menunjukkan kedua ekor anjing mengalami perdarahan di berbagai organ, bentuk jantung double apex, hipertrofi ventrikel kiri, chicken fat clot di ventrikel kanan dan kardiomiopati, kongesti paru-paru dan bronkitis, stomatitis ulseratif, gastritis ulseratif, enteritis mukopurulenta, hati ikterus dan kongesti, splenitis dan nefritis interstisial kronis. Hasil pemeriksaan histopatologi paru-paru menunjukkan bronkheolitis dengan banyak koloni bakteri dan sel radang netrofil, serta nefritis interstitialis kronis dengan glomerulopati. Kardiomiopati menyebabkan kegagalan jantung yang berakibat kongesti pada seluruh organ. Kematian pada kedua ekor anjing ini disebabkan sepsis, kegagalan fungsi organ terutama jantung, hemoragik shok, dan uremia.

Judul: Studi Kasus Ehrlichiosis pada Anjing Ditinjau dari Gambaran Hematologi dan Kimia Darah
Abstrak: Ehrlichiosis merupakan penyakit infeksius pada anjing yang disebabkan oleh bakteri intraselular gram negatif dari genus Ehrlichia. Penyakit ini apabila tidak ditangani dapat menyebabkan septikemia dan berujung pada kematian. Studi kasus ini dilakukan untuk mempelajari gambaran hematologi dan kimia darah anjing penderita ehrlichiosis. Data yang digunakan merupakan data sekunder yang diperoleh dari pemeriksaan hematologi dan kimia darah dua ekor anjing ras Labrador Retriever dan German Sepherd yang sebelumnya terkonfirmasi positif terinfeksi Ehrlichia sp menggunakan 4DX snap test-IDEXX®. Interpretasi hasil pemeriksaan hematologi dan kimia darah dikaitkan dengan sinyalemen, anamnesis, gejala klinis, dan temuan patologi anatomi organ-organ. Hasil pengamatan menunjukkan bahwa kedua ekor anjing mengalami perubahan gambaran hematologi dan kimia darah berupa anemia, trombositopenia, leukopenia, limfopenia, hiperglobulinemia, hipoalbuminemia, dan azotemia. Gambaran hematologi dan kimia darah anjing ras Labrador Retriever disertai juga dengan neutropenia, hiperbilirubinemia, dan peningkatan enzim Alkaline Phosphatase (ALP), sedangkan anjing German Shepherd disertai dengan eosinopenia dan hiperproteinemia. Gambaran hematologi dan kimia darah yang dikonfirmasi dengan temuan histopatologi menunjukkan kedua ekor anjing mengalami gangguan ginjal.

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
