Judul: Aspek Terapi Diropilaria Immitis Pada Anjing
Abstrak: Dirofilaria immitis adalah merupakan parasit yang ditularkan melalui vektor penghisap darah, dalam berbagai literatur lebih dikenal sebagai Heartworm. Cacing ini menyerang anjing terutama didaerah tropis dan subtropis serta bersifat kosmopolitan. Secara alamiah cacing ini dapat ditularkan kepada anjing, kucing, rubah dan serigala. Menurut Leidy (1856), infeksi banyak terjadi terutama di daerah selatan benua Eropa, India, Jepang, Cina, Austra lia, Amerika utara dan Amerika selatan. Menurut Hungerford (1966), infeksi juga terjadi didaerah Queensland dan New- South Wales. Di Indonesia ada laporan sebelumnya bahwa ca cing ini menginfeksi anjing-anjing di jawa, Sumatra, Kali- mantan dan Palembang. Sedang menurut laporan dari hasil be dah bangkai, yang dilakukan oleh bagian Pathology FKH-IPB, selama periode 1983-1985, ditemukan adanya 5 kasus Dirofila ria immitis pada anjing. Anjing merupakan induk semang utama cacing jantung, akan tetapi jenis anjing yang banyak diserang adalah jenis anjing pacu dan pemburu, (Mallack et al, 1971). Pada tahun 1965 Beaver dan Orihel, menemukan adanya 11 kasus Dirofilaria immitis pada manusia di Amerika serikat, sedang frekwensi kejadian Dirofilariasis pada manusia, banyak terjadi di Amerika selatan.

Judul: Aspek klinis dan patologi klinis Dirofilaria Immitis pada anjing, suatu tinjauan pustaka
Abstrak: Dirofilariasis merupakan penyakit parasiter yang disebabkan oleh cacing Dirofilaria immitis atau Heart worm. Cacing ini termasuk kelas Nematoda, familia Filariidae, dan genus Dirofilaria (Soulsby, 1965). D. immi- tis menyerang anjing, kucing, srigala dan rubah di. Eropa bagian selatan, India, Cina, Jepang, Australia, Amerika Utara dan Amerika Selatan (Georgi, 1980). Secara umum cacing ini tersebar di daerah tropis, subtropis serta di beberapa daerah beriklim sedang. Di Indonesia cacing ini juga sering ditemukan (Adiwinata, 1955). D. immitis dewasa hidup di dalam arteria pulmonalis dan ventrikel kanan jantung, tetapi pernah ditemukan juga dalam bronchiole, otak, mata, kista interdigital dan vena cava posterior (Jackson, et al., 1962). Dibbel et al. (1951) pernah melaporkan adanya D. immitis betina di dalam ruang perut anjing Dalmatian yang telah dimandulkan. ...

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
