Mapping of Leptospirosis Risk Factor Based on Remote Sensing Image in Tembalang, Semarang City, Central Java

---

Leptospirosis is a zoonotic disease, caused by leptospira bacteria and transmitted to human by contact though contaminated animal urine and environment. Tembalang Sub District is endemic area of leptospirosis and increased at last three years. The aim of this research was to study the ability and usefulness of image remote sensing for mapping as distribution of leptospirosis, physical environment of risk factor analysis.

This cross sectional design consisted of 246 leptospirosis subjects mapped with GPS, and processed by using ArcGis 92 program. Leptospirosis case was overlaid with remote sensing (Quickbird image), then is done interpretation of spatial feature, and digitation on screen to visual identify of risk factor.

Based on digital visualization leptospirosis cases in 2009 were clustered in Tembalang with shortest distance index 0,009 km and is furthermost 18 km. More case distribution found at children and men adolescent. Temporally, case increased in the dry season, among of July and August. Result of visual interpretation and digitation can obtain land use map, water body, settlement, fl oods area, vegetation index and height.

Spatial high resolution remote sensing image is very good for mapping of leptospirosis risk factor. Leptospirosis case distribution forms the cluster in Tembalang; case is predominated by children and men adolescent. (Health Science Indones 2012;1:45-50)
