Dengue Hemorrhagic Fever (DHF) is a disease caused by the dengue virus and transmitted by the Aedes aegypti mosquito. The working area of the Rawasari Health Center in Jambi City shows a trend of increasing dengue cases from year to year. This indicates that there may be other factors influencing the incidence of dengue, including physical environmental conditions and community behavior. The objective of this research is to determine the relationship between the presence of mosquito larvae in water reservoirs/containers, the action of hanging clothes, using mosquito repellent, cleaning water containers, disposing of waste items, and installing wire mesh with the incidence of dengue fever in the working area of the Rawasari Health Center in 2025. This research uses a quantitative study, with a case control design. The sample size consisted of 24 cases and 24 controls determined by matched case control study techniques based on age and gender. Data were collected through questionnaires and observation sheets, and analyzed using the chi-square test to determine the relationship between the independent variables and the incidence of dengue fever. The results show that the presence of mosquito larvae in water storage containers (p-value 0.042), practices of cleaning water storage containers (p-value 0.020), actions to eliminate waste items (p-value 0.043), and the installation of screens or mosquito nets (p-value 0.004) are significantly related to the incidence of dengue fever. Conversely, other factors such as the habit of drying clothes and the use of mosquito repellent did not show a statistically significant relationship with dengue fever cases in the study population. There is a significant relationship between the actions of cleaning water storage places and installing wire mesh. Effective prevention requires active community involvement in maintaining environmental cleanliness and consistently implementing the 3M Plus practices.

The existence of waste at this time was still a problem that hit almost all regions in Indonesia. Keliling Danau Districts in 2019 has produces 33,311 m3 of waste per year with a population of 22,207 people.

This study aims to determine the relationship between knowledge, attitudes, and Availability of Facilities with Waste Management in State Elementary School 52 of Koto Dian students, Kerinci Regency. This research is quantitative with a cross sectional research design. Sampling using random sampling technique with a total sample of 44 students consisted of class III, IV, V to class VI. Data was collected by distributed of questionnaires. Analysis used chi-square test. The results of this study indicate that 18 of 44 (40.9%) respondents with poor behavior of waste management and 26 (59.1%) respondents with good behavior waste management. From the results of the bivariate test, it was found that Knowledge has a PR value = 3.33 CI = 1.73-6.39 and a p-value of 0.001 indicates that there is a relationship between knowledge and behavior of waste management. Attitude has a value of PR = 3.75 CI = 1.62-8.68 and a p-value of 0.001 indicates that there was a relationship between attitude and behavior of waste management and there was not relationship between availability of facilities and behavior of waste management with a p-value of 0.222. The conclusion of this study is that there is a relationship between knowledge and attitudes with behavior waste management. And the availability of facilities has no relationship between behavior of waste management in elementary school students.
