Judul: Analysis of Factors Affecting the  Economic Growth Rate of Sleman Regency with a Path Analysis Approach
Abstrak: Pertumbuhan ekonomi suatu wilayah dapat dihitung dengan beberapa pendekatan, yaitu salah satunya dengan pendekatan pengeluaran menggunakan Produk Domestik Regional Bruto (PDRB). Terdapat beberapa komponen yang diperhitungkan pada perhitungan PDRB tiap tahunnya. Dari komponen-komponen tersebut dilakukan analisis jalur atau path analysis untuk mengetahui komponen yang menjadi faktor dominan terhadap laju pertumbuhan ekonomi Kabupaten Sleman. Sebelum dilakukan path analysis, dilakukan uji asumsi klasik terlebih dahulu berupa uji normalitas agar model yang dihasilkan dari path analysis merupakan model yang baik. Dari hasil implementasi, diperoleh komponen impor barang dan jasa paling berpengaruh terhadap laju pertumbuhan ekonomi Kabupaten Sleman., The economic growth of a region can be calculated with several approaches, one of which is the expenditure approach using the Gross Regional Domestic Product (GRDP). There are several components that are taken into account in the calculation of GRDP each year. From these components, path analysis is carried out to determine the components that became the dominant factors in the economic growth rate of Sleman Regency. Before path analysis is carried out, the classical normality assumption was checked to make sure that the resulting path analysis model is a good one. From the implementation results, it is obtained that the import component of goods and services has the biggest influence on the economic growth rate of Sleman Regency.

Judul: Analisis Struktur Perekonomian dan Faktor-Faktor yang Memengaruhi Pertumbuhan Ekonomi Sumatera Selatan
Abstrak: Pertumbuhan ekonomi Provinsi Sumatera Selatan selama lima tahun terakhir berfluktuasi dengan kecenderungan meningkat. Namun demikian Pendapatan Domestik Regional Bruto (PDRB) per kapita Sumatera Selatan relatif rendah bila dibandingkan dengan provinsi lain di Sumatera. Sepanjang tahun 2006 – 2010 rata-rata PDRB per kapita Sumatera Selatan sebesar 3,28 persen, lebih rendah dibandingkan dengan Jambi dengan pertumbuhan rata-rata sebesar 4,14 persen, Sumatera Utara sebesar 5,08 persen atau Lampung dengan rata-rata pertumbuhan 4.2 persen. Dengan demikian perlu kiranya bagi Provinsi Sumatera Selatan untuk berupaya meningkatkan terus laju pertumbuhan PDRB. Dalam menganalisis pembangunan di daerah ada satu hal yang menarik yaitu mengapa terdapat perbedaan dalam pertumbuhan ekonomi satu daerah dengan daerah lain. Perbedaan tersebut ternyata disebabkan adanya perbedaan dalam karakteristik antar daerah. Karakteristik daerah itu sendiri sebetulnya dapat dilihat dari kontribusi tiap-tiap sektor perekonomiaan terhadap pembentukan PDRB. Kontribusi tiap-tiap sektor pada suatu daerah dapat pula dibandingkan dengan daerah lain yang lebih tinggi, untuk menentukan apakah suatu sektor merupakan sektor yang mengekspor atau bukan. ...

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.
