Dengue fever is still one of the main health problems that threaten people in Indonesia, including Jambi City. Tahtul Yaman neighbourhood, Jambi Province is one of the residential areas that has dengue fever data. In general, most residents use water tanks, the environment looks less clean, and there are still puddles and water reservoirs in the homes of some residents. This activity aims to provide knowledge and understanding to the community about dengue fever and its mitigation strategies, with an emphasis on prevention through vector control, especially the Aedes aegypti mosquito. This counselling will be focused on the Tahtul Yaman Village community. The method used was lecture method and interactive discussion using powerpoint, posters and leaflets on DHF and 3M Plus. After the education, there was an increase in knowledge reaching 89.25%. It is suggested that prevention efforts should focus on controlling the larval population and minimising mosquito breeding sites. Mosquito eradication programmes such as 3M Plus need to be carried out routinely and involve the active participation of the entire community. Effective dengue prevention will create a healthier and safer environment for the community.

Dengue Hemorrhagic Fever (DHF) is an infectious disease that is influenced by the environment and people's behavior. In Jambi City, Dengue Fever is still a public health problem. This research aims to distribute dengue hemorrhagic fever (DBD) incidence in Jambi City. This research uses Global Moran's analysis and Local Indicator of Spatial Association (LISA) to determine the Hot Spot and Cold Spot areas for dengue cases in Jambi City in 2018 -2022 with a sub-district analysis unit of 62 sub-districts. During 5 years of observation, the results showed that the distribution pattern of dengue fever cases was in the form of a clustered pattern (I>E[I]) in 2018-2022. The research results on the distribution of dengue fever cases from 2018-2022 showed that the lowest cases were in 2021, namely 132 cases, while the highest cases were in 2019, 698 cases. The results of this study are expected to provide an overview of the distribution of dengue fever incidence in Jambi City in 2018 - 2022 so that it becomes a recommendation material for the Jambi City Health Office or the Jambi City Government in an overview of environmental factors related to dengue fever incidence in Jambi City to prevent various diseases due to poor environmental sanitation in Jambi City. Knowing the distribution pattern of dengue fever can determine regional priorities in implementing dengue fever prevention and control intervention programs in Jambi City.
