Judul: Infeksi Parasit Darah pada Sapi Perah di Kawasan Usaha Ternak (KUNAK) Cibungbulang, Kabupaten Bogor
Abstrak: Kasus penyakit yang disebabkan oleh parasit darah umumnya bersifat kronis, namun pada beberapa kasus ada yang bersifat akut. Kerugian ekonomi yang disebabkan oleh penyakit parasit darah dapat berupa pertumbuhan terhambat, penurunan bobot badan, penurunan daya reproduksi, penurunan produksi susu, dan abortus. Penelitian ini bertujuan untuk mengetahui keberadaan parasit darah dan tingkat parasitemia pada sapi perah di kawasan usaha ternak (KUNAK) Cibungbulang, Kabupaten Bogor. Terdapat 100 sampel darah sapi perah dalam penelitian ini yang terdiri dari 21 sampel dari kelompokm umur ≤ 2 tahun dan 79 sampel dari kelompok umur >2 tahun. Variabel yang diamati adalah presentase hewan yang terinfeksi dan tingkat infeksi dengan mengetahui persentase parasitemia. Hasil penelitian dari 100 sampel ditemukan 69 ekor yang terinfeksi (69%). Ada 3 jenis parasit darah yang ditemukan dalam penelitian ini yaitu Babesia sp., Anaplasma sp. dan Theileria sp.. Persentase hewan terinfeksi parasit tertinggi yaitu Theileria sp. (50%), kemudian Anaplasma sp. (15%) dan terendah Babesia sp. (4%).Persentase parasitemia pada berbagai tingkat umur memiliki nilai sama yaitu kurang dari 1%, yang tergolong dalam tingkat parasitemia rendah

Judul: Studi Kasus Infeksi Parasit Darah pada Sapi Potong di Kabupaten Subang, Jawa Barat
Abstrak: This study describes prevalence of blood parasites and parasitemia level using blood smear. Result of the experiment of blood samples in 62 cattle from Subang Regency showed a blood parasite infection by Babesia sp., Theileria sp., and Anaplasma sp. The inapposite maintenance management was thought to be main factor causing infection. This supported by hipotesis chi square test which states, that maintenance management relates to prevalence. In this research, also performed calculations average parasitemia to measure level of parasitosis by age level and gender cattle. The calculations show parasitosis level mild because obtained average parasitemia <1%. Statistical tests average parasitemia (Babesia sp., Theileria sp., and Anaplasma sp.) age level significantly different (p<0.05) in calf and adult cattle. By sex were also obtained significantly different results (p<0.05) in bulls and cows for blood parasites Anaplasma sp.

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.
