Judul: Epidemiologi infeksi virus parvo pada anjing di DKI Jakarta
Abstrak: Pada tahun 1988 belum pernah terbukti tentang keberadaan virus parvo di Indonesia baik secara serologis maupun virologis, namun gambaran klinis yang menyerupai infeksi parvo sudah ditemukan. Sekarang ini kasus parvo sudah banyak ditemukan namun Epidemiologi penyakit ini belum diketahui secara pasti. Tujuan penelitian ini untuk mengetahui faktor apa saja yang terlibat dalam timbulnya infeksi oleh virus parvo pada anjing. Data yang digunakan dalam studi ini berasal dari Rumah Sakit Hewan Jakarta, Badan Meteorologi dan Geofisika, Biro Pusat Statistik dan Dinas Peternakan. Analisis satistika yang digunakan adalah uji cluster, khi-kuadrat, korelasi, dan deskripsi. Hasil analisis menunjukkan bahwa di Jakarta infeksi CPV terjadi secara endemik dan terbentuk lima kelompok anjing berdasarkan uji cluster. Berdasarkan analisis statistik khi-kuadrat menunjukkan tendensi infeksi virus parvo menyerang anak anjing (80%), anjing tidak divaksin (78%) dan anjing jantan (58%). Kecepatan angin dan curah hujan tidak berkorelasi nyata (P>0,05) sedangkan kelembaban dan temperatur udara berkorelasi nyata terhadap infeksi virus parvo (P<0,05) pada tahun 1996 dan 1998. Bila dirata-rata tiap tahun, pada bulan Juli kasus parvo paling banyak ditemukan....

Judul: Kejadian Penyakit Distemper dan Parvo pada Anjing Melalui Pendekatan Klinis, Studi di Rumah Sakit Hewan Institut Pertanian Bogor
Abstrak: Dog’s viral diseases, such as Distemper and Parvo have a high morbidity and mortality rate. There is no cure, the treatment is only based on the clinical signs which veterinarian could see. Vaccination is the only way to prevent these viral diseases. Based on Animal Hospital Bogor Agricultural University’s data, in Parvo case, pure breed dogs have a higher incidence rate than local and mix breed dogs. Then the age of infected dogs under 1 year with the highest incidence rate at age 3-6 months, whereas the male gender has a higher incidence rate than female. For the case of Distemper, mix breed dogs have a higher incidence rate compared with pure breed dogs. Age of Distemper infected dogs are varied between 2 months to 1 year and there is no gender specific has the higher-level events. Study which is conducted at Animal Hospital Bogor Agricultural University to obtain secondary data of the Distemper and Parvo suspects, as comparison to another secondary data of Bogor’s climate. Changes of rainfall amount as one of weather elements can indirectly affect the incidence of disease Parvo and Distemper, but has no specific pattern. This is seen in both Parvo and Distemper cases, but the number of Parvo cases more than Distemper because CPV is more resistant due to the environment and easily mutate.

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
