Judul: Profil Leukosit Sapi Friesian Holstein Penderita Endometritis.
Abstrak: Pendekatan manajemen kesehatan ternak merupakan aspek penting untuk menjamin produktivitas susu sapi perah. Penelitian ini bertujuan untuk mengetahui leukosit sapi Friesian Holstein (FH) penderita endometritis di Lembang dan Pangalengan Jawa Barat. Parameter penelitian meliputi jumlah leukosit dan diferensiasi leukosit yang meliputi neutrofil, eosinofil, basofil, limfosit, dan monosit. Sampel darah diambil dari vena coccygeal dari 20 ekor sapi FH 1-5 bulan dari partus. Sampel darah dibagi menjadi 2 bagian, 1 bagian untuk perhitungan total leukosit dan 1 bagian untuk pembuatan apus darah. Parameter leukosit dianalisis secara deskriptif kemudian dilanjutkan dengan uji independent T-test untuk menunjukkan bahwa hasilnya berbeda nyata (P<0.05). Berdasarkan hasil, 85% sapi endometritis menunjukkan total leukosit dan neutrofil lebih tinggi dan berbeda nyata (P<0.05) dibandingkan sapi negatif endometritis. Rata-rata eosinofil, basofil, limfosit, dan monosit sapi endometritis lebih tinggi dibandingkan sapi negatif endometritis. Secara umum total leukosit dan diferensiasi leukosit sapi endometritis lebih tinggi dibanding sapi negatif endometritis. Sapi endometritis mengalami infeksi secara kronis.

Judul: Profil Sel Darah Merah dan Mineral Makro pada Sapi Perah Penderita Endometritis di Jawa Barat
Abstrak: Endometritis adalah peradangan pada selaput lendir uterus, yang pada umumnya disebabkan oleh infeksi bakteri. Penelitian ini bertujuan untuk mengetahui profil sel darah merah dan mineral makro sapi perah penderita endometritis di Jawa Barat. Sapi perah 1-5 bulan postpatus diperiksa menggunakan ultrasonografi (USG) untuk mendeteksi kondisi endometritis. Pengambilan sampel darah dilakukan melalui vena coccygea kemudian disimpan dalam vacutainer EDTA dan vacutainer plain. Pemeriksaan hematologi yang dilakukan meliputi jumlah sel darah merah, kadar hemoglobin, nilai hematokrit dan indeks sel darah merah, sedangkan pemeriksaan mineral makro meliputi kadar kalsium, kadar fosfor dan kadar magnesium. Hasil menunjukkan bahwa sapi perah positif endometritis 30.77% anemia normositik hipokromik yang ditandai dengan penurunan jumlah sel darah merah, kadar hemoglobin, nilai hematokrit, dan indeks sel darah merah. Sapi perah penderita endometritis postpartus sebanyak 55.56% menunjukkan hipokalsemia subklinis, 5% menunjukkan hipofosfatemia, dan 58.83% menunjukkan hipermagnesemia.

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.
