【 摘 要 】
Environmental factors change such as built-up area density, vegetation density, moisture and temperature can affect the health problems. Dengue Fever Disease (DFD) that are still high rates of incidence because of environmental factors change in Indonesia including Surakarta City. The purpose of this study are mapping environmental factors consisting of built-up area density, vegetation density, land surface moisture (LSM) and land surface temperature (LST) in Surakarta City 2002 and 2015 through image transformation and correlation analysis of environmental factors change on the evidence of DFD in Surakarta City. This research uses Landsat-7 ETM+, Landsat-8 OLI/TIRS and the evidence of DFD data on 2002 and 2015. Landsat image is processed by using LST, VGNIR-BI to be built-up area density, NDVI for vegetation density, NDMI for LSM. Based on the result of image transformation, built-up area density and LST in Surakarta City increased from 2002-2015, while vegetation density and LSM tended to decrease. The result of this research shows that the environmental factor change in the form of built-up area density, vegetation cover density, LSM and LST have correlation are 74%, 68%, 75% and 69% of the evidence of DFD in Surakarta, respectively. Overall, the environmental factors correlated 86.1% of the evidence of DFD in Surakarta City.
