Analisis Pola Spasial Penyakit Demam Berdarah Dengue di Kota Bandung Menggunakan Indeks Moran

ABSTRACTBandung has the highest case of dengue fever in West Java, which is 3134 cases in 2014. The spread of dengue fever can be analyzed spatially by spatial autocorrelation to find out the correlation relationship pattern between locations. The method of spatial autocorrelation was using the Moran Index method. From these methods can determine the relationship of spatial autocorrelation in the spread of dengue fever and determine spatial distribution pattern of dengue fever in Bandung. The results of spatial autocorrelation analysis shows the spatial autocorrelation in dengue hemorrhagic cases in Bandung, the one-way significance test indicates a positive autocorrelation in Dengue hemorrhagic cases in Bandung and spatial distribution pattern is the spatial distribution pattern of the cluster.Kata kunci: spatial autocorrelation, spatial pattern, Moran Index, dengue fever.ABSTRAKKota Bandung merupakan kota yang mempunyai kasus penyakit demam berdarah tertinggi di Jawa Barat yang berjumlah 3134 kasus pada tahun 2014. Sebaran penyakit demam berdarah dapat dianalisis secara spasial yaitu dengan autokorelasi spasial untuk mengetahui pola hubungan korelasi antar lokasi. Metode autokorelasi spasial yang digunakan adalah metode Indeks Moran. Dari metode tersebut dapat menentukan hubungan autokorelasi spasial dalam penyebaran penyakit demam berdarah dan menentukan pola sebaran spasial penyakit demam berdarah di Kota Bandung. Dari hasil analisis autokorelasi spasial menunjukan terdapat autokorelasi spasial pada kasus demam berdarah dengue di Kota Bandung, uji signifikansi satu arah menunjukan adanya autokorelasi positif pada kasus demam berdarah Dengue di Kota Bandung dan pola sebaran spasial dihasilkan adalah pola spasial sebaran cluster.Keywords: Autokorelasi Spasial, Pola Spasial, Indeks Moran, demam berdarah.

Using methods of spatial autocorrelation analysis and trend analysis, the paper studies the spatial distribution pattern of NDVI based on the GIMMS NDVI dataset (1998-2008), in Western Jilin. The maximum value for 15d is got through the method of MAX processing. Results show that: the NDVI in growing season shows a rising trend in western Jilin in 1998-2008. In the study area, the NDVI in Western Jilin shows positive spatial autocorrelation in the whole region, but the partial NDVI is apt to scattered distribution, which means the vegetation cover of Western Jilin is generally fragmental.
