Judul: Prospek pengembangan usaha peternakan sapi potong di Kecamatan Bawang Kabupeten Banjarnegara
Abstrak: Kelemahan internal terdiri dari tingkat pendidikan yang rendah, harga konsentrat yang relatif mahal, informasi dan penyuluhan peternakan kurang dan posisi tawar- menawar peternak yang lemah. Peluang dari segi eksternal usaha sapi potong terdiri dari pangsa pasar yang terbuka, pemanfaatan dan pengembangan hasil ikutan pertanian, potensi daya tampung wilayah dan pengembangan teknologi pakan (pemanfaatan jerami padi). Ancaman eksternal meliputi penyakit ternak sapi potong, penjualan ternak sapi potong yang kurang terkontrol dan banyaknya pesaing dari daerah lain. Faktor internal dan eksternal menentukan posisi pengembangan peternakan sapi potong di Kecamatan Bawang. Hasil total skor yang diperoleh dari analisis faktor internal adalah total skor kekuatan dikurangi total skor kelemahan sebesar 2,59 dan total skor faktor eksternal adalah total skor peluang dikurangi dengan total skor ancaman sebesar 2,33. Strategi yang sesuai dalam pengembangan usaha peternakan sapi potong di Kecamatan Bawang berada pada kuadran dimana wilayah tersebut memiliki kekuatan untuk memanfaatkan peluang. Strategi yang diterapkan yaitu strategi mendukung kebijakan pertumbuhan yang agresif (Growth Oriented Strategy) Prioritas strategi berdasarkan hasil analisis matrik SWOT adalah strategi WO (Weaknesses-Opportunities) yang meliputi : a. melakukan pengembangan teknologi pakan untuk mengantisipasi harga konsentrat yang relatif mahal, b. memberikan pelatihan untuk mengembangkan hasil ikutan dan teknologi pakan guna menambah pengetahuan peternak dan c. meningkatkan peran kelompok ternak dalam posisi tawar-menawar dan menguasai pangsa pasar sapi potong di Kabupaten Banjarnegara. Srategi ini dianggap prioritas karena diharapkan dengan cara tersebut dapat meningkatkan produktivitas peternak baik pengetahuan maupun keterampilan sehingga dapat berdampak kepada peningkatan produksi dan pendapatan peternak.

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.
