Dengue Hemorrhagic Fever (DHF) in Tuban Regency was an important health problem. Bangilan sub-district is a sub-district in Tuban Regency which has high dengue cases. The Bangilan Health Center has not used mapping or spatial analysis in its surveillance activities for dengue cases. Disease mapping is useful in assisting surveillance activities and making it easier for us to find out the spread of the house index in each village area. The purpose of this study is to analyze the spatial house index with dengue cases in Bangilan District, Tuban Regency. This type of research is descriptive analytic. The population in this study is a house around DHF patients with a radius of 100 m from the patient's house in Bangilan District, with a total sample of 774 houses. The research variables were cases of DHF and house index. DHF cases in 2020-2022 were obtained from secondary data from the Bangilan Health Center, while the house index was obtained from the larvae survey results. The data were analyzed to determine the effect of the house index and dengue cases using the GeoDa application. The results showed that the average house index in Bangilan District was 20.8% which according to WHO was high. The pattern of spread of DHF cases is random with an Average Nearest Neighbor value = 1 and the results of Moran's Index (I) = 0.061, meaning that there is a strong spatial autocorrelation effect on the house index with DHF cases.

Dengue Hemorrhagic Fever (DHF) in Indonesia has increased from year to year. Community usually used chemical insecticides to control dengue fever. However, the continuous use of chemical insecticides will have a negative impact on the environment and humans and the possibility of resistance to mosquitoes. An alternative that can be done is to use a bioinsecticide made from noni leaves (Morinda Citrifolia L.) which contains flavonoids, saponins and alkaloids. This study aimed to analyze the toxicity of noni leaf (Morinda citrifolia L.) as an electric mat to the death of the Ae. aegypti. The type of research is a quasi-experimental study with a posttest only research design with a control group design using 4 variations of 1 gram, 1.5 gram, 2 gram, 2.5 gram with five repetitions. The samples used were 25 Ae. aegypti mosquitoes.  Statistical analysis used is One Way Anova Test and Probit Test. The results of the average percentage of deaths during 24 hours of observation were 30%, 41%, 54% and 68%. One Way Anova test showed the value (p-valuee=0.000). The probit test showed the LC50 of 1.735 gram/6m3. The conclusion of this research is noni leaf has toxicity to kill the Ae. aegypti mosquito. However, its effectiveness is still below the WHO requirements because it has not reached 90%.

The house fly is a mechanical vector for spreading diseases. Controlling flies using chemical repellents continuously could results in resistance to flies. The other alternative is using clove leave filtrate as a natural repellent. The content of clove leaves that have function as a repellent are: eugenol, saponins, and flavonoids. The purpose of this study was to analyze the effectiveness of clove leaf filtrate as a natural repellent against house flies. The space spraying method was carried out with an air diffuser and exposed for 6 hours. This type of research uses a simple quasi-experiment with a post test only control group design. The study used clove leaf concentrations of 10%, 15%, 20%, aquadest, and was replicated 6 times. The number of house flies used are 600. The result showed that the average flies that refused bait on the control was 28%, the concentration of 10% was 61.3%, 15% was 84%, and 20% was 91.3%. The results of the One Way Anova test, stated the p-value of 0.000 (<0.05), which means that there is a difference in the average number of house flies that refuse bait.The conclusion of this study is that clove leaf filtrate is effective as a house fly repellent.
