Judul: Penerapan Regresi Logistik dan Regresi Spasial pada Penetapan Kebijakan Anggaran Pendidikan (Studi Kasus: Alokasi Anggaran Pendidikan Kabupaten/Kota untuk Wilayah Indonesia Bagian Timur)
Abstrak: Constitutional Court Decision No. 13 / PUU-VI I in 2008, the government must provide education budget at least 20% from national budget and regional budget. However, in reality there are some areas that have not been allocated a budget of education at least 20%. Variables education budget is divided into two. First, education budget which have surpass 20% and education budget which below 20% of regiomal budget. Second, the percentage of education budget allocation from total regional budget. Logistic regression is used to observe the effect of the regional characteristics to fulfillment of the education budget policy in accordance with the decision of the Constitutional Court. Some of the characteristics examined include: population based of education, revenue-sharing, special allocation fund, the general allocation fund, poverty, and enrollment. Unlike the Logistic Regression, spatial regression is used to see the effect of the spatial variables used. From the analysis of logistic regression, there are three variables that affect the determination of the education budget policy. The third variable is the general allocation fund, a special allocation fund, and area. While the spatial regression analysis, obtained five variables that affect the percentage of the education budget allocation. These five variables include: revenue-sharing, general allocation fund, a special allocation fund, the number of people who graduated from college, and enrollment at age 19-24.

Abstrak: Geographically Weighted Logistic Regression (GWLR) model is locally logistic regression model. The data in this model is assumed following Binomial distribution and the geographical factor is considered. The geographical factor is used to analyze spatial data from nonstationary processes. The basic idea of this model consider the geography or location as the weight in parameter estimation. The parameter estimator is obtained from Iteratively Reweighted Least Square method by giving different weight for different location. Model for determining the poverty level with a global logistic regression was not suitable to be applied in all districts of East Java Province, because it could be a predictor effect on the poverty level in the region but in other regions the predictor is not significant. The data in this research is from National Social Economy Survey 2008. This research will determine the factors that affect the poverty level in the East Java Province using logistic regression model and GWLR model with a weighting adaptive bi-square kernel function. The results showed that the classification accuracy of logistic regression model was 78.90% and the classification accuracy of GWLR model was 89.47%. GWLR model with a weighting adaptive bi-square kernel function was better than logistic regression model because it had the high classification accuracy and small AIC value.

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.
