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: Penentuan Faktor-Faktor yang Mempengaruhi Angka Partisipasi Sekolah dengan Pendekatan Regresi Spasial (Studi Kasus: 26 Kabupaten/kota di Provinsi Jawa Barat Tahun 2011)
Abstrak: West Java is a province with the largest population in Indonesia which 5.23% of its are high school-age, has a great responsibility to promote education in the region. One of the indicators used to assess educational progress is the School Participation Rate (SPR). The SPR has a spatial effect across the region, so that the method used in this study is Geographically Weighted Regression (GWR). The purpose of this study was to determine the variables which affect the SPR in West Java Province for 2011. The research’s result show that the variables that affect the SPR in West Java Province year 2011 are the ratio of sum of teachers to school-age population (%) and the percentage of poverty. High living cost in the western part of West Java Province led to unequal number of poverty in this province. This problem can affect the SPR so that the percentage of poverty need to be considered to increase the SPR in this region. In the eastern part of West Java Province, the access teacher’s education facilities in this area are difficult, it led to unequal, so that teacher’s education facilities need to be considered to increase the SPR in this region.

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%).
