Information obtained from the Madiun City Health and Family Planning Office from 2013 to 2020 shows that in 2020 there was a remarkable increase after experiencing a decline in 2017. The process of direct socialization to the community is still difficult, and there is no web-based mapping of the spread of dengue fever in Madiun.

It is hoped that this geographic information system can help related parties to make it easier to convey information about the spread of dengue fever, especially within the Madiun City area, and as an effort to anticipate the expansion of its distribution area. The identification of regional groups in this system is divided into categories, namely Endemic, Sporadic, Potential, and Free. Grouping, using clustering method based on K-Means logic.
