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.

Judul: Model Regresi Logistik Terboboti Geografis (Studi Kasus : Pemodelan Kemiskinan di Provinsi Jawa Timur)
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: Natural Pearlescent Pigment Dari Kristal Guanin Sisik Ikan Bandeng (Chanos Chanos)
Abstrak: Pearlescent pigment yang dikenal dengan nama pearl essence atau fish silver merupakan pigmen berwarna keperakan yang memiliki kenampakan seperti mutiara. Natural pearlescent pigment diperoleh dari sisik ikan dengan kandungan guanin 75-97%, dan kini mulai banyak digunakan pada industri personal care dan produk kosmetika. Penelitian ini bertujuan untuk menentukan teknologi ekstraksi natural pearlescent pigment dan karakteristik kualitatif kristal guanin pada sisik ikan bandeng (Chanos chanos). Perlakuan dalam penelitian ini meliputi ekstraksi menggunakan air deionisasi dengan sisik yang dibekukan terlebih dahulu, air deionisasi 10 οC, dimetil sulfoksida 15%, dan 25% (v/v). Hasil spektrum absorbansi UV-Vis menunjukkan kristal guanin merupakan pigmen berwarna putih berdasarkan serapan pada panjang gelombang 200-800 nm. Hasil terbaik diperoleh pada ekstraksi menggunakan air deionisasi dengan sisik beku nilai kristalinitas 68,4%, serapan gugus amina pada 3410 cm-1 dan gugus amida pada1681 cm-1, puncak intensitas 2θ pada sudut 27,7° yang menunjukan identitas dari kristal guanin anhidrat. Tingkat kandungan guanin sebesar 0,0455 ± 0,0033 g (0,46%).
