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: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
