Judul: Regresi Terboboti Geografis untuk Analisis Pendapatan Asli Daerah Kabupaten/kota di Provinsi Aceh
Abstrak: Original Local Government Revenue (PAD) is one of the important sources of income that has to be used optimally in order to decrease the dependency aid towards the central government and the provincial government. PAD of a regency/municipality in Aceh are influenced by spatial dependence and spatial heterogenity. Spatial dependence and spatial heterogenity can be overcome by using Geographically Weighted Regression (GWR). GWR models with Gaussian kernel weighted grouped regency/municipality in Aceh into seven groups based on the independent variables associated with the PAD of a regency/municipality. Overall, the independent variables associated with PAD of a regency/municipality in Aceh are the total population, the number of hotels, the number of tourist attraction, the number of large and medium industries, per capita GRDP, and the number of tourists. Variables that have the highest contribution to the PAD of a regency/municipality in Aceh are the number of hotels, number of tourist attraction, and the number of large and medium industries. The R2 value of the overall GWR models is 83.81%, while the R2 value of the GWR models for each regency/muncipality ranges from 73.17%-85.89%

Judul: Analisis Faktor-faktor yang Mempengaruhi Pendapatan Asli Daerah (PAD) Dan Komponen PAD Provinsi Banten.
Abstrak: Tujuan penelitian ini adalah (1) Mengetahui perkembangan PAD Dan komponen PAD Provinsi Banten selama tahun 2002-2008 (2) Menganalisis faktor-faktor yang mempengaruhi PAD dan komponen PAD di Provinsi Banten pada tahun 2002-2008. Untuk melihat Perkembangan PAD Dan Komponen PAD menggunakan analisis deskriptif, sedangkan analisis faktor-faktor yang mempengaruhi PAD dan komponen PAD dengan menggunakan analisis regresi linier berganda dengan metode Ordinary Least Squared (OLS), dengan menggunakan software E-Views 4.1. Hasil penelitian menunjukan selama tahun 2002-2008, kontribusi PAD terhadap penerimaan APBD Provinsi Banten cenderung terus meningkat dari 52,91 persen menjadi 70,65 persen. Sedangkan Komponen PAD yang memberikan kontribusi dominan yaitu rata-rata di atas 95 persen adalah pajak daerah sedangkan retribusi daerah memberikan kontribusi yang paling rendah. Berdasarkan hasil analisis regresi linier berganda, menunjukan bahwa pajak daerah dipengaruhi oleh jumlah kendaraan bermotor dengan nilai koefisien regresi sebesar 0.14 persen dengan asumsi variabel lainnya konstan atau hal ini menunjukan jika kendaraan bermotor meningkat sebesar satu persen maka penerimaan pajak daerah naik sebesar 0.14 persen. Selain dipengaruhi jumlah kendaraan bermotor pajak daerah juga dipengaruhi oleh pendapatan perkapita penduduk dengan nilai koefisien regresi sebesar 0.06 persen hal ini menunjukan jika pendapatan perkapita meningkat satu persen akan meningkatkan penerimaan pajak daerah sebesar 0.06 persen. Sedangkan PAD dipengaruhi oleh jumlah kendaraan bermotor dan pendapatan perkapita, dengan nilai koefisien regresi masing-masing sebesar 0.14 dan 0.07 hal ini menunjukan bahwa jika kendaraan bermotor meningkat satu persen maka penerimaan PAD meningkat sebesar 0.14 persen begitupun dengan meningkatnya pendapatan perkapita sebesar satu persen akan meningkatkan penerimaan PAD sebesar 0.07 persen dengan asumsi variabel lain dianggap konstan.

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.
