Analisis Spasial Faktor Lingkungan dan Kejadian DBD di Kabupaten Demak
Dengue Haemoragic Fever (DHF) was still a public health problem in Demak District, Central Java. In the year of 2012, there were 483 DHF cases and 6 of them were died. Based on those cases, there was no clear information how those cases spread related to environmental and demographic factor.
This research aimed to do spatial analysis of DHF incidence then it was related to House Index (HI), Container Index (CI), and the density of houses and occupant. It was an observational research using survey method.
This Research took 150 samples of DHF cases. The site of DHF incidence was identified using Geographic Positioning System (GPS) device, to gained its coordinat. Environmental and demographic data was collected based on secondary information from District Health Office of Demak. The colected data would be analyzed spatially using ArcView GIS software.
This research showed that there was no association between environmental factors (HI, CI) with the Incidence Rate (IR) of DHF (p-value < 0,05). However, the level of HI and CI was 13,17% and 7,08% respectively. It was a potential condition for DHF spreading in the community. Spatial analysis indicated that Mranggen Sub-district had the most number of DHF incidence that the pattern of spreading covered all area of villages. The higher of population and house density, the higher of Incidence Rate of DHF
