Judul: Infeksi Neospora caninum: Kajian Morfopatologi
Abstrak: Neospora caninum is an intracellular obligate parasite newly recognized in late 1980’s. Neosporosis caused neuromuscular dysfunction (progressive lameness, hindlimb paresis and paralysis) in dog and abortion in cow. The dog is a definitive host of Neospora caninum. Cow, sheep, goat, horse, deer, water buffalo, rhinocheros, and fox could be an intermediate host. Gross examination was found in heart, liver, central nervous system, dan skeletal muscle. Histopatological examination demonstrated multifocal necrosis of brain, interstisial non-suppurative myocarditis, and multifocal inflammation in liver. This study reviews information on pathomorphological, pathogenesis, prevention, and treatment of neosporosis

Judul: Neosporosis Sapi: Studi Pendahuluan di Lore Barat, Kabupaten Poso, Sulawesi Tengah.
Abstrak: Neospora caninum is recognized as a major cause of serious abortion in varieties of wild and domestic animals around the world especially in cattle. This disease causes severe economic losses among dairy and beef cattle due to the loss of foetus as well as a decrease in milk and meat production, which is believed as an opportunistic zoonotic agent. A cross-sectional study was carried out to determine the prevalence of Neospora caninum antibodies in cattle from five villages in West Lore Subdistrict of Poso Regency, Central Sulawesi, Indonesia. Serum samples were collected from 44 local beef cattle tested for detection of immunoglobulin (Ig) G antibodies against N. caninum using an indirect multi-species enzyme-linked immunosorbent assay (ELISA) commercial test. Seroprevalence of Neospora caninum in local beef cattle in West Lore, Poso Regency, Central Sulawesi is 11.36%. Gender and ages have not affected the prevalence of this parasite. This study gives information about the first serological evidence for the presence of natural N. caninum infection in local beef cattle from West Lore. It is recommended to do further investigations and to design suitable controlling strategies., Neospora caninum dikenal sebagai penyebab utama aborsi pada hewan liar dan domestik di seluruh dunia, terutama pada sapi. Penyakit ini menyebabkan kerugian ekonomi yang parah pada sapi perah dan sapi potong karena sapi kehilangan fetusnya, serta terjadi penurunan produksi susu dan daging. Parasit ini termasuk sebagai agen zoonosis oportunistik. Kajian lintas seksional dilakukan untuk mengetahui prevalensi antibodi Neospora caninum pada sapi dari lima desa di Kecamatan Lore Barat Kabupaten Poso, Sulawesi Tengah, Indonesia. Sampel serum dikumpulkan dari 44 sapi potong lokal untuk mendeteksi antibodi imunoglobulin (Ig) G terhadap N. caninum menggunakan indirect multi-species enzyme-linked immunosorbent assay (ELISA). Seroprevalensi Neospora caninum pada sapi potong lokal di Lore Barat, Kabupaten Poso, Sulawesi Tengah adalah sebesar 11,36%. Jenis kelamin dan usia tidak mempengaruhi prevalensi parasit ini. Penelitian ini memberikan informasi tentang bukti serologis pertama adanya infeksi N. caninum alami pada sapi potong lokal di Lore Barat. Disarankan untuk melakukan investigasi lebih lanjut prevalensi parasit tersebut pada anjing sebagai sumber infeksi horizontal agar dapat merancang strategi pengendalian yang tepat.

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
