Judul: Studi Kasus di Kelurahan Brebes dan Kelurahan Limbangan Wetan, Kabupaten Brebes, Jawa Tengah
Abstrak: Telur itik banyak mengandung protein bila dibandingkan jenis telur lainnya. Kandungan protein dan lemak itik lebih besar yaitu mengandung 17 gram protein dan 34 gram lemak serta 377 kal/butir, sehingga efektif sebagai sumber penghasil energi. Tetapi pengolahan telur segar menjadi telur asin sebagai salah satu hasil olahan telur itik masih sangat kurang. Pengolahan tersebut masih merupakan home industry

Judul: Respons biologik itik tegal terhadap pakan pertumbuhan dengan berbagai kadar protein
Abstrak: Ternak itik walaupun bukan ternak asli Indonesia, telah mampu beradaptasi baik dengan lingkungan Indonesia, sehingga dapat dianggap sebagai ternak lokal. Peranan ternak itik bukan saja memberikan lapangan kerja dan sumber pendapatan rakyat di pedesaan, tetapi juga menjadi sumber telur konsumsi kedua setalah ayam ras. Walaupun populasi itik di Indonesia (26.025 juta) termasuk populasi tertinggi untuk itik petelur di ASEAN, namun di Indonesia ternak itik masih merupakan ternak yang kurang mendapatkan perhatian dalam usaha-usaha untuk meningkatkan potensinya sebagai sumber pangan maupun hasil sampingan seperti bulunya. Dari penelitian-penelitian yang menggunakan itik lokal dapat disimpulkan bahwa antara 390 - 50 persen dari itik lokal adalah itik-itik yang rendah potnsinya dalam produksi telur, namun selebihnya adalah itik-itik yang mempunyai potensi produksi telur yang tinggi.

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.
