Judul: Kajian serologis Bovine Viral Diarrhea (BVD) pada sapi potong impor di Daerah Banten
Abstrak: Bovine Viral Diarrhea (BVD) is an acute epizootic disease and often causes death which characterize by clinical symptoms such as diarrhea and erosive lesions in the gastrointestinal tract. The agent caused this BVD is a pestivirus, family Flaviviridae. This disease is a strategic infectious disease that should be concerned in Indonesia. The aim of this research was to asses this BVD’s diseases in imported cattle at Banten. Enzyme linked immunosorbant assay (ELISA) is one of the methods that can be used to detect of BVD virus infection. Samples which were used in BVD’s serological test in Banten were 230 samples. There were 173 (75.22%) samples showed positive results of BVD while about 57 (24.78%) samples showed negative of BVD.

Judul: Kajian Penyakit Bovine Viral Diarrhea (BVD) pada Sapi Potong Impor Di Pelabuhan Tanjung Priok.
Abstrak: Virus Bovine viral diarrhea (BVD) merupakan penyakit ternak yang sangat infeksius. Virus ini menyebabkan kerugian ekonomi akibat bermacam macam gejala klinis yang ditimbulkan dan merupakan subjek penyakit yang masuk dalam program penanggulangan dan pemberantasan di seluruh dunia. Infeksi BVD memiliki patogenesis yang sangat komplek, dengan infeksi sebelum dan sesudah kebuntingan yang menyebabkan gejala klinis yang bervariasi. Infeksi virus selama kebuntingan menghasilkan infeksi pada fetus, yang dapat menyebabkan kematian embrio dini, efek teratogenik atau hewan yang memiliki infeksi persisten. Hewan dengan status infeksi persisten akan mengeluarkan virus BVD melalui eksresi dan sekresi selama hidupnya dan merupakan rute transmisi utama dalam penularan virus ini. Penelitian ini bertujuan untuk melakukan suatu kajian serologis tentang penyakit BVD dan mengidentifikasi faktor risiko yang berkaitan dengan pemeliharaan kandang sebagai sumber penularan penyakit BVD pada sapi potong impor. Penelitian ini diharapkan dapat memberikan informasi pencegahan yang efektif dalam perkembangan penyakit BVD pada sapi potong impor asal Australia di feedlot Instalasi Karantina Hewan BBKP Tanjung Priok. Sebanyak 100 sampel darah diambil dari bulan Juli dan Agustus 2014 dengan metode acak sederhana di lima daerah Instalasi Karantina Hewan (IKH) yaitu feedlot di Cianjur, Bogor, Tangerang, Bandung, dan Subang. Kelima wilayah ini merupakan daerah kerja karantina hewan Balai Besar Karantina Pertanian Tanjung Priok. Pengujian darah terhadap virus BVD dilakukan dengan menggunakan enzyme-linked immunosorbent assay (ELISA) antibodi sebagai uji screening awal dan apabila didapatkan hasil positif dilanjutkan ke uji ELISA antigen. Hasil pengujian menunjukkan bahwa 63% (63 dari 100 sampel) positif pada uji ELISA antibodi. Faktor risiko yang terkait dengan penyebaran penyakit BVD selama dalam masa pemeliharaan dan penggemukkan dalam penelitian adalah penerapan biosekuriti pada peternakan (OR=3.316; CI=1.380-7.967) dan pengelolaan limbah kandang dalam peternakan (OR=2.667; CI=1.105-6.434).

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.
