Judul: Analisis Pola Konsumsi Mahasiswa Terhadap Pangan Asal Ternak (Studi Kasus: Mahasiswa Program Sarjana Fakultas Ekonomi dan Manajemen Institut Pertanian Bogor Tahun Masuk 2010)
Abstrak: FEM Students have a diverse characteristic, which rise to differences in consumption decisions, one of which is the consumption of the food from livestock. This study aims to analyze the consumption pattern of the food from livestock, identify the factors that influence the demand for the food from livestock, and analyze the level of price and income elasticity of the food from livestock with the application of the Almost Ideal Demand System (AIDS) model. The results of this studies showed that the higher the students income, the lower the total expenditure of FEM students allocated to consumption of food from livestock. The largest proportion of total expenditure of FEM students is used for the consumption of chicken meat, followed by cow’s milk, eggs of chicken, and beef. The own price variable, cross-price, total expenditure, gender, residence status tends to be dominant significantly affect the proportion of food from livestock expenditure on the real level (α) of 0,10. The own price elasticity of beef, chicken meat, and eggs is inelastic while the own price elasticity of cow’s milk is elastic. Most of cross-price elasticity have negative sign, its mean that the livestock has the complementary relationship with other food from livestock. The income elasticity for chicken meat, and eggs of chicken shown the value less than one, its mean that commodities are a staple goods. The income elasticity for beef and cow’s milk shown the value more than one, its mean that commodity is considered luxury good

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.
