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: Deteksi Serologis Infeksi Neospora caninum pada Kerbau di Kabupaten Sumba Timur
Abstrak: Neospora caninum adalah protozoa parasit penyebab neosporosis pada ternak ruminansia seperti sapi dan kerbau. Kerbau merupakan ternak yang memiliki nilai ekonomi maupun budaya sebagai sarana penting dalam pelaksanaan upacara adat di daerah tertentu. Neosporosis pada kerbau telah diketahui dapat menyebabkan kerugian ekonomi di berbagai negara. Data kejadian neosporosis pada kerbau di Indonesia masih sangat terbatas. Penelitian ini bertujuan untuk mendeteksi keberadaan infeksi Neospora caninum (N. caninum) pada kerbau di Kabupaten Sumba Timur melalui deteksi serologis. Sebanyak 36 sampel serum kerbau dari 10 kecamatan diperiksa keberadaan antibodi terhadap N.caninum menggunakan metode uji ELISA tidak langsung. Berdasarkan uji yang dilakukan, infeksi N.caninum terdeteksi di sepuluh kecamatan asal sampel dengan tujuh diantaranya memiliki proporsi seropositif sebesar 100%. Secara keseluruhan proporsi N.caninum pada kerbau di Kabupaten Sumba Timur sebesar 77,78%. Penelitian ini menunjukkan bukti serologis adanya infeksi N.caninum di Kabupaten Sumba Timur. Penyempurnaan data epidemiologi N.caninum perlu dilakukan untuk mencegah penyebaran dan pengendalian penyakit yang tepat., Neospora caninum is a protozoan parasite that causes neosporosis in ruminant cattle such as cows and buffaloes. Aside from its economic value, buffalo also has an important cultural value for traditional ceremonies in certain places. Neosporosis in buffaloes can cause economic loss in many countries. Data on the neosporosis incidence in buffalo in Indonesia is very limited. This study aimed to detect the presence of Neospora caninum (N. caninum) infection from 36 archived buffalo serum samples taken from 10 sub districts of Sumba Timur Regency using the indirect ELISA test method. Based on the serological test, the antibody against N. caninum was detected in all sub districts of the sample origin and 7 subdistricts found to have a seropositive proportion of 100%. The total proportion of N. caninum infection found in buffalo at Sumba Timur Regency is 77,78%. This is the first study that shows serological evidence of N. caninum infection in buffalo in the Sumba Timur Regency. Improvement of N. caninum epidemiology data needs to be done to control and prevent the spread of the disease.

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
