Judul: Analisis daya saing dan efisiensi ekonomi sistem komoditas telur ayam ras di Sumatera Barat
Abstrak: Tujuan penelitian ini adalah (1) menganalisis efisiensi finansial dan ekonomi sistem komoditas telur ayam ras di propinsi Sumatera Barat, salah satu daerah produksi telur ayam ras di Sumatera yang tidak ditunjang oleh keberadaan industri sarana produksinya dan (2) menganalisis dampak kebijakan pemerintah terhadap usaha ayam ras petelur. Penelitian dilakukan di Kabupaten 50 Kota dan Kotamadya Payakumbuh yang merupakan daerah sentra utama produksi telur ayam ras di Propinsi Sumatera Barat. Penelitian lapangan dilakukan pada bulan September-November 1998

Judul: Analysis of business administration eggs in  Kabupaten Lima Puluh Kota, Sumatera Barat
Abstrak: Industri Peternakan ayam ras petelur semakin berkembang di Indonesia terbukti dengan meningkatnya jumlah pengusaha peternakan ayam ras petelur dan produksi yang dihasilkan meningkat. Potensi Indonesia sebagai penghasil telur ayam bisa lebih dimaksimalkan lagi agar sektor ini dapat memberikan kontribusi terhadap PDB nasional. Kabupaten Lima Puluh Kota adalah daerah yang memiliki populasi ayam ras petelur terbesar dan memproduksi telur ayam ras terbesar. Meskipun potensi Kabupaten Lima Puluh Kota sangat besar pada produksi telur ayam ras, masih diperlukannya untuk menganalisis saluran, fungsi-fungsi tataniaga, margin tataniaga, farmer’s share, dan rasio keuntungan dan biaya dalam mengukur seberapa efisien sistem tataniaganya. Metode yang digunakan yaitu melaui analisis margin, farmer’s share, dan rasio keuntungan dan biaya. Dengan mempergunakan metode ini diharapkan dapat menganalis seberapa efisien sistem tataniaga di Kabupaten Lima Puluh Kota. Dalam penelitian Analisis Tataniaga Telur Ayam Ras di Kabupaten Lima Puluh Kota, Sumatera Barat ada beberapa lembaga tataniaga yang terlibat yaitu Peternak, pedagang pengumpul, pedagang besar, dan pedagang pengecer dalam menyalurkan telur ayam ras sampai ke tangan konsumen akhir. Fungsi tataniaga yang dilakukan oleh peternak dan lembaga tataniaga yaitu fungsi pertukaran, fungsi fisik dan fungsi fasilitas.

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.
