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.

Dengue Hemorrhagic Fever (DHF) remains a major public health issue in Indonesia, particularly in endemic areas like Simpang III Sipin Village. This disease is transmitted by Aedes sp mosquitoes, and the presence of their larvae is a key indicator of the potential spread of DHF. Environmental conditions, such as water reservoirs and humidity, alongside community behaviors, play significant roles in supporting the growth of these mosquito larvae. Therefore, research is needed to identify the factors influencing the presence of Aedes sp larvae. Methods: This study utilized a cross-sectional design with a quantitative approach. The sample consisted of 143 households, selected using purposive sampling techniques. Data were collected via questionnaires and direct observations. Additionally, measurements of environmental conditions such as air humidity and temperature were taken using a hygrothermometer. The variables under study included knowledge, attitudes, behavior regarding water reservoir drainage (TPA), number of TPAs, air humidity, and air temperature. Results: Data analysis was conducted using the Chi-Square statistical test to determine the relationships between the variables. The results indicated that factors like knowledge level (p = 0.008), attitude (p = 0.008), behavior related to draining water reservoirs (p = 0.001), number of water reservoirs (p = 0.013), and air humidity (p = 0.004) were significantly related to the presence of Aedes sp larvae. However, air temperature did not show a significant relationship (p = 0.675). Conclusion: High humidity environments encourage the growth of mosquito larvae, and insufficient knowledge and inadequate preventive behaviors contribute to increased mosquito populations, exacerbating the risk of DHF transmission.

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.

      Dengue Hemorrhagic Fever (DHF) is an acute viral-febrile disease, often characterized by headache, bone or joint pain and muscle, and rash as a symptom. In Indonesia in 2011 there were 65,432 cases with 595 deaths. East Java Province has determined outbreaks of DHF since 2015 in 37 districts / cities, with a total of 3,136 cases of dengue fever and 52 deaths. Pasuruan Regency is one of Kabupeten in East Java with the highest death rate from DHF compared to other regencies or cities, which is 28 people in 2020. There are many factors that can affect, pray the only environment and vector. The purpose of this research is to see the relationship of environmental factors and vector with the incidence of DBD in Pasuruan Regency. This research is an observational research with case control design. The sample in this research were 76 respondents consisting of 38 case groups and 38 control groups representing from 3 sub-districts in Pasuruan Regency (Gempol, Beji and Kraton Sub-district). Data analysis with Chi-Square test. The results showed that there was a relationship between water pH in house (p = 0.005, OR = 5,343), indoor air temperature (p = 0.046, OR = 3,221), air humidity in house (p = 0.049, OR = 3,923) and presence of larvae (p = 0.037, OR = 3.032) with the incidence of DHF in Pasuruan Regency. The most influential factor in increasing the risk of DHF incidence in Pasuruan Regency is the pH of water, the temperature inside the house and the presence of larvae around the house. It needs cross-sector cooperation to pay attention to the condition of environmental sanitation so it will not be a good place for Ae mosquito development. aegypti. Providing counseling to people who focus on the source of the problem, and the community in order to prevent the occurrence of transmission of DHF by breaking the chain of transmission.
