Spatial Pattern Analysis on Dengue Hemorrhagic Fever (DHF) Disease in Tanjung Emas Port Area using Moran Index

Abstract

Tanjung Emas Port area is the State’s entrance in Semarang City’s administrative area. Data shows a significant increase of Dengue Hemorrhagic Fever (DHF) disease cases from 38 cases in 2018 to 137 cases in 2019. The objective of research was to conduct a spatial analysis using spatial autocorrelation to find out the correlation pattern between locations. A descriptive and analytical observational study of 137 coordinate points of DHF patients was carried out for mapping purpose. This research employed spatial autocorrelation with Moran’s Index. Using such the method, the spatial autocorrelation of DHF spread can be determined, and so can be the spatial distribution of DHFin Tanjung Emas Port area, Semarang. Spatial autocorrelation analysis showed Moran’s Index value of 0.192725 at interval of 0 < I ≤ 1 indicating positive spatial autocorrelation; Moran’s index>0 indicates the Cluster spread pattern. One-way significance test showed the positive autocorrelation in Dengue hemorrhagic fever case in Tanjung Emas Port and cluster spread spatial pattern.
