Dengue Hemorrhagic Fever (DHF) is one of the diseases that threaten human health. The cases of dengue fever in the district / city certainly has different characteristics, geographic condition, the potential of the region, health facilities, as well as other matters that lie behind them. Based on local moran index values are visualized through thematic maps, some area adjacent quadrant tends to be in the same group. There are two significant quadrant in describing the pattern of spread of dengue cases namely quadrant high-high and lowlow. This indicates a spatial effect on the number of dengue cases, so that the spatial regression analysis. Based on the value of and AIC, autoregressive spatial models (SAR) is good enough to be used in modeling the number of dengue cases in the province of Central Java. Factors that influence the number of dengue cases Central Java province in 2015 is the number of health centers per 1000 population, the number of polindes per 1000 population, population density (X3), percentage of people with access to drinking water sustainable decent (X6), the percentage of water quality net free of bacteria, fungi and chemicals (X7), and the number of facilities protected springs (X8).

The growing number of vehicle in each year resulting an inevitable congestion, one of them is jamming vehicle transaction in Tembalang toll gate. This condition can cause dissatisfaction to the toll road users in obtaining services. It is need to be specified the appropriate queue system model to the conditions of service in Tembalang toll gate. So it can be determined the number of booth service is working optimally. Based on the data analysis obtained from the Arena software, the queue system model that can describe the conditions of service at Tembalang toll gates with data total- time, time-total, and time-time the direction of Srondol-Jatingaleh at the regular toll booth is (Norm/G/2):(GD/∞/∞), (G/Norm/2): (GD/∞/∞), (G/G/2): (GD/∞/∞) and at the automatic toll booth is (G/Tria/3): (GD/∞/∞), (Tria/G/3): (GD/∞/∞), (G/G/3): (GD/∞/∞) while with the direction of Jatingaleh-Srondol at the regular toll booth is (Norm/G/3): (GD/∞/∞), (G/Norm/3): (GD/∞/∞), (G/G/3): (GD/∞/∞) and (G/Tria/2): (GD/∞/∞), (Tria/G/2): (GD/∞/∞), (G/G/2): (GD/∞/∞) at automatic toll booth.

Konsumen saat ini memiliki banyak pilihan untuk berbelanja memenuhi kebutuhan sehari-hari, baik di pasar modern maupun tradisional, serta ritel khususnya dalam bentuk minimarket. Dengan demikian persaingan antar minimarket juga sangat tinggi. Setiap minimarket memiliki strategi pemasaran yang berbeda-beda, karena karakteristik konsumen dalam berbelanja juga berbeda-beda. Dalam strategi pemasaran, informasi dari berbagai aspek, yaitu dapat dari segi konsumen, pasar, pesaing, maupun produk sangat diperlukan. Pada penelitian ini melakukan analisis factor yang berpengaruh pada minat konsumen yang berbelanja di minimarket. Factor yang dikaji adalah dari segi konsumen, baik karakteristik maupun lokasi tempat tinggal. Data yang digunakan adalah data primer dengan melakukan survey wawancara pada konsumen di Kecamatan Ngaglik, Kab. Sleman, DIY. Sedangkan sampel minimarket adalah Indomaret. Metode analisis yang digunakan adalah regresi logistik dan Classification and Regression Trees (CART). Hasil analisis menunjukkan bahwa faktor-faktor yang signifikan berpengaruh terhadap minat belanja di Indomaret dengan metode regresi logistik adalah variabel jenis kelamin, pengeluaran rata-rata perbulan, dan lokasi tempat tinggal konsumen. Sedangkan factor berperan penting dalam pembentukan pohon klasifikasi CART adalah juga lokasi. Apabila dibandingkan berdasarkan nilai ketepatan klasifikasi, metode CART, sebagai metode nonparametrik yang tidak memiliki asumsi distribusi tertentu, menghasilkan ketepatan klasifikasi yang lebih tinggi dibandingkan regresi logistik.
