ANALISIS SPASIAL FAKTOR LINGKUNGAN DAN KEJADIAN DBD DI KABUPATEN DEMAK

Abstract

Abstract 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). Meskipun demikian, nilai rata-rata HI dan CI di Kabupaten Demak sebesar 13,17% dan 7,08%. Kondisi ini berpotensi terjadi penularan DBD yang tinggi di masyarakat. Hasil analisis spasial menunjukan bahwa sebaran kasus DBD terbanyak terjadi di Kecamatan Mranggen dengan pola sebaran merata di seluruh desa. Ada kecenderungan semakin tinggi kepadatan penduduk dan kepadatan rumah semakin tinggi pula IR DBD (p-value < 0,05). Kata kunci: analisis spasial DBD, faktor lingkungan, Kabupaten Demak
