Dengue Hemorrhagic Fever (DHF) is a disease caused by a virus transmitted by a mosquito vector of Aedes . As Semarang city of Indonesia has dense population and is located in a low altitude area, Semarang is identified to be a high endemic area of DHF. The objective of this study was to describe the risk factors of DHF, specifically larva density and environmental condition, using spatial analysis. The descriptively observational research with cross sectional approach was used and samples were taken using proportional stratified random sampling technique in Tembalang sub-district on 100 households. Data obtained through questionnaires, observations, and measurements were analyzed by spatial method. The result showed that the description of the risk factor was as follows: larva density (CI) was still above the national standard of Indonesia by 5%. The behavior of respondent of Semarang city belonged to the category of poor, and the majority of respondents were not routinely doing elimination of mosquito breeding sites.
