Judul: Malignant catarrhal fever pada rusa
Abstrak: Tujuan penulisan skripsi ini adalah untuk mempela- jari dan membahas keadaan rusa yang terkena Malignant Catarrhal Fever, proses kejadian penyakitnya, cara pe- nularan, etiologi, dan sejumlah aspek penting lainnya. Malignant Catarrhal Fever pada rusa adalah penyakit yang ditandai dengan adanya disentri, reaksi malignant catarrhal fever tipikal seperti demam, eksudasi, kebeng- kakan limfoglandula, infiltrasi sel mononuklear dan vas- kulitis yang sering menyebabkan kematian pada hewan tan- pa didahului gejala klinis. Proses penularan diduga ada dua kemungkinan, dari wildebeest (gnu) atau domba (gheep-Associated MCF). Yang paling diduga keras adalah akibat sheep-Associated MCF, di mana rusa ada kontak dengan virus domba yang sel associated terhadap MCF. Cara pengendalian yang efektif adalah menjaga pe- ngelolaan rusa sedemikian rupa sehingga tidak mengadakan kontak dengan domba yang mungkin mengandung virus yang sel associated terhadap MCF. Pengontrolan dan pengendalian yang baik merupakan jalan yang paling aman dalam rangka mencegah terjadinya penyakit MCF pada rusa, karena belum adanya vaksin untuk mencegah MCF pada rusa, dan juga pengobatan terhadap kasus MCF belum memberikan arti yang serius.

Judul: Peranan domba dalam penularan malignant catarrhal fever
Abstrak: milik Tujuan penulisan skripsi ini adalah mempelajari gambaran umum dari Malignant Catarrhal Fever yang dikaitkan dengan domba (SA-MCF Sheep Associated Malignant Catarrhal Fever), terutama tentang peranan domba dalam penularan penyakit, cara penularan, etiologi serta beberapa aspek pen- ting yang lain. Sheep Associated Malignant Catarrhal Fever (SA-MCF) adalah penyakit yang ditandai dengan demam, eksudat mukopu rulen dari mata dan hidung, kekeruhan (opasitas) cornea bi lateral yang berjalan secara sentripetal, pembengkakan lim foglandula yang meluas terutama bagian anterior tubuh, in- filtrasi sel-sel mononuklear dan vasculitis yang meluas, dan penularannya ke sapi atau hewan peka dikaitkan dengan domba yang diduga sebagai reservoir atau carrier, tetapi mekanisme penularannya belum diketahui. Meskipun telah berhasil diidentifikasi berbagai macam virus, namun agen penyebab yang pasti dari SA-MCF ini belum bisa ditetapkan. Hubungan antigenik agen penyebab SA- MCF dengan virus WA-MCF (Wildebeest Associated Malignant catarrhal fever) belum tersimpulkan. Unive Cara pengendalian yang dianjurkan adalah tidak memelihara sapi atau hewan peka bersama-sama domba…

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
