Abstract
Finding larvae and determining the home location of Dengue Hemorrhagic Fever (DHF) sufferers are a method used by researchers for entomological surveys. Early DHF vector surveys are carried out the same however with the addition of field data processing based on larval surveys that led to the development of the "Dengue Monitoring Evaluation with GIS" (DME-GIS) technology. DME-GIS is a computerized system for data collection, transmission prediction based on the distance of the location of the house, and the distance between residents and villages in real-time. The current study illustrates the first experience with a system to monitor DHF vectors and presents preliminary results in two villages namely Putat Jaya, and Banyu Urip, Surabaya, Indonesia which are analyzed by (DME-GIS) technology. Survey DHF vector larvae and record data on homeowners, age and breading places at each location with a distance of 100 meters. The Preliminary results of this study indicate as a strategy to identify the main areas and direct the steps of controlling DHF vectors early. There is a red layer point as a sign of a DHF case, a yellow layer point as a sign of larvae at the location being examined and, a polygon layer as a sign of the Sawahan Surabaya sub-district as the research location. Spatial data analysis uses buffer analysis as a method for effective DHF distribution control. Based on the DHF case layer and larva positive cases it is known that the distribution of DHF spreads in the region therefore quick and precautionary control measures can be implemented. Application of the buffer analysis method demonstrate this control strategy with house-to-house visits within a radius of 100 m from positive sufferers and larvae monitoring. Additionally, this technology system is expected to monitor as an early warning of the spread of DHF by vectors.
