Judul: Analisis permintaan konsumen rumah tangga terhadap telur ayam ras di Desa Margabakti Kecamatan Cibeureum dan Kelurahan Sukamulya Kecamatan Indihiang Tasikmalaya
Abstrak: Pertumbuhan ekonomi di segala sektor mengakibatkan meningkatnya pendapatan masyarakat, baik di kota maupun di pedasaan. Hal ini menunjukkan pengaruh nyata terhadap konsumsi pangan masyarakat, pada gilirannya akan mempengaruhi kemampuan untuk meningkatkan gizinya, terutama yang bersumber dari protein hewani yang relatif murah dan mudah di dapat sehingga yang berpendapatan menengah ke bawah lebih banyak mengkonsumsinya dibandingkan dengan daging sapi atau susu. Telur merupakan salah satu komoditas hewani yang berprotein tinggi serta murah dan mudah didapat, maka hal tersebut yang mendorong rumah tangga untuk mengkonsumsi telur. Tujuan penelitian ini adalah untuk menganalisis perilaku pembelian telur ayam ras konsumen rumah tangga, menganalisis faktor-faktor yang mempengaruhi jumlah permintaan konsumen rumah tangga terhadap telur ayam ras dan menganalisis elastisitas permintaan telur ayam ras di Desa Margabakti dan Kelurahan Sukamulya. ..

Judul: Permintaan rumah tangga konsumen terhadap telur ayam ras di Kecamatan Kandis, Kabupaten Siak, Riau
Abstrak: To day, egg is one of the primary consumption, because its price is relative low and as sources of protein. Prosperity of the people could be seen from the supply of nutrient. It is related with consumption and income. This research was held in Kandis Sub District, Siak District , Riau on September 1th 2th 2007. There were 60 housewives in Kandis Sub Diaict as respondents. The accidental sampling is used to pick the respondents. The result shows that cross elasticity of egg consumption was 17,8. There are three significant factors to egg consumptions in Kandis Sub District, they are price's egg of buras chicken, total of family member and taste. Total of egg consumption by holsehold consumer is 10,33 Kg/capita/year . The people in Kandis consume egg as protein source.

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.
