Judul: Pengaruh Pemberian Tepung Daun Katuk,Torbangun, dan Sirih Terhadap Produksi dan Kualitas Susu pada Kambing Sapera
Abstrak: Penelitian ini bertujuan untuk mengetahui pengaruh pemberian tepung daun katuk, torbangun, dan sirih terhadap produksi, kualitas susu serta status mastitis subklinis kambing perah sapera laktasi. Rancangan percobaan yang digunakan yaitu Rancangan Acak Kelompok (RAK) dengan tiga perlakuan dan tiga ulangan. Perlakuan yang diberikan yaitu T1 (Ransum Basal+tepung daun katuk 2%), T2 (Ransum Basal+tepung torbangun 2%), dan T3 (Ransum Basal+ tepung daun sirih 2%). Peubah yang diukur dalam penelitian yaitu konsumsi nutrien, produksi susu, efisiensi produksi susu, kualitas susu, dan status mastitis subklinis. Data dianalisis dengan sidik ragam (ANOVA). Hasil penelitian menunjukkan bahwa tidak ada perbedaan antara T1, T2 dan T3 pada setiap peubah yaitu konsumsi nutrien, produksi susu, efisiensi produksi susu dan kualitas susu. Kesimpulan dari penelitian ini menunjukkan bahwa pemberian tepung daun sirih dapat menurunkan status mastitis subklinis.

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.
