Abstract Background: Dengue hemorrhagic fever (DHF), one type of infectious disease caused by the dengue virus, is still becoming a public health problem in Indonesia.
The high number of dengue cases in Indonesia, especially in Kendari City itself, is closely related to environmental conditions, especially when it is known that the city has entered the rainy season.
Objective: This study aimed to identify and analyze the factors associated with the presence of mosquito eggs trapped in ovitraps DHF-endemic area in Kendari City.
Indonesia.
Methods: This study used an analytic observational approach with a cross-sectional design.
The research sample in this study was 50 houses located in endemic areas of Kendari selected using simple random Data were collected by observation using a checklist sheet and direct observation in each room of the respondent's house based on lighting, temperature, humidity, and physical environmental conditions, as well as the presence of mosquito eggs or larvae trapped in the ovitrap.
The analysis was carried out in two stages, namely univariate analysis and bivariate analysis using the Chi-Square test.
Result: From 50 houses observed, 13 houses .
%) had the presence of mosquito eggs, 42 houses .
%) had bad air temperature, 19 houses .
%) had poor humidity, and 35 houses .
%) had a higher frequency.
In addition, the temperature, lighting, and environmental conditions did not have a significant relationship with the presence of mosquito eggs in ovitraps in endemic areas of Kendari City, with p-values of 0.
94, 0.
52, and 39, respectively.
In contrast, the humidity factor has a significant relationship with the presence of eggs with a p-value of 0.
Conclusion: There was a significant relationship between humidity and the presence of mosquito eggs in ovitraps in endemic areas of Kendari City.
Indonesia.
It is recommended that residents increase Mosquito Nest Eradication (PSN) activities, perform selective abatization, and disseminate information about DHF through counseling or other activities conveyed through health workers with full support from community leaders and adjusted to the level of education of the local population.

Background Dengue hemorrhagic fever (DHF) has become a public health problem in Indonesia (Tosepu, 2.
Dengue virus infection can be transmitted through mosquito bites (Yunus & Rosanty, 2016.
Alhamda, 2.
, and the types of mosquitoes that can be a source of transmission of dengue hemorrhagic fever are mosquitoes of the Aedes aegypti and Aedes albopictus species (Wertheim et al.
, 2012.
Tosepu.
Tantrakarnapa.
Worakhunpiset, et al.
, 2.
Dengue hemorrhagic fever is a seasonal disease that always appears every year.
As if endless.
DHF is a disease that infects many people in tropical and subtropical areas.
Asia, especially Indonesia, ranks first in the number of dengue fever sufferers every year (Tosepu.
Tantrakarnapa.
Nakhapakorn, et al.
Especially for Indonesia, high rainfall allows dengue cases to increase when the rainy season arrives (Tosepu.
Tantrakarnapa.
Nakhapakorn, et , 2.
However, mosquito larvae are still able to breed in puddles so that they can still grow every This is coupled with environmental conditions and sanitation in many areas in Indonesia which are far from healthy (Widoyono, 2008.
Siswanto et al.
Preliminary studies carried out by research still found several mosquito larvae in several residents' homes, and the survey results found the larvae-free rate (ABJ) was at least 60%.
The presence of larvae in an area is known by the indicator of the larva-free ABJ is the percentage of houses or public places where larvae are not found.
Low ABJ is influenced by several factors.
The behavior of the population in terms of storing water for daily needs is not only in one place, and rarely cleaning water reservoirs allows the Aedes aegypti mosquito to have more opportunities to lay eggs (Sitorus & Ambarita, 2.
According to Hasyimi and Soekirno .
, the most common Aedes aegypti larvae or pupae found in household landfills are household landfills made of metal.
The type of household landfill that most commonly found larvae or pupae of Aedes aegypti was the jar type landfill.
There are three types of TPA found positive for Aedes aegypti larvae inside or outside the house, namely drums, bathtubs, and plastic buckets (Sitorus & Ambarita, 2.
The high number of dengue cases in Indonesia, especially in Kendari City, is closely related to environmental conditions, especially since Kendari City has entered the rainy season.
There are still many people who do not understand the environmental conditions that can trigger the spread of dengue fever.
Environmental conditions are conditions that can affect the development of Aedes aegypti mosquito larvae.
DHF vector breeding and resting places such as containers filled with water, humidity, lighting, and air temperature can be a big threat to the spread of DHF disease (Anwar & Rahmat, 2.
Therefore, this study aimed to analyze the factors associated with the presence of mosquito eggs trapped in the ovitrap DHF-endemic area in Kendari City.
Indonesia.
Based on data from the Ministry of Health of the Republic of Indonesia in 2020, the total cases of DHF in Indonesia reached 95,893 cases, and 661 people died from the disease.
The total cases of DHF were spread across 472 districts/cities in 34 provinces, with deaths from dengue hemorrhagic fever reported from 219 districts/cities.
In November 2020, there were 51 additional cases of dengue fever and one additional death report due to dengue hemorrhagic fever.
In addition, 73.

The cases were spread in 15 regencies and cities, and the most cases were in Kendari City, around 291 cases, and the lowest cases were in the Buton district.

The results of house lighting observations found that the distance of the respondent's house, which was quite close, affected the intensity of light that could enter the house, and there were still many trees around the house, so that the lighting was less than This provides an opportunity for mosquitoes because a place with minimal light will be used as a place to rest.
However, based on the results of the Chi-Square test, it was found that there was no relationship between lighting and the presence of eggs .

The results of this study were not in line with the research of Werdinigsih et al.
on the relationship between physical environmental conditions and the presence of mosquito larvae that there was a relationship between lighting conditions and the presence of mosquito larvae with a p-value of 0.
The absence of a significant relationship between lighting and the presence of eggs in this study is because most residents often open doors or windows in the morning and afternoon so that there is still sunlight coming in.
Humidity ranges from 60%-80% is the optimal humidity to help the embryonication process and mosquito larvae resistance.
At a humidity of less than 60%, the lifespan of a mosquito will be short because it will affect the mosquito's respiratory system so that if it is in low humidity, it will cause evaporation of the mosquito's body (Wijirahayu & Sukesi, 2.

However, further research is needed, especially with a larger population and sample coverage.
It is also recommended for residents to increase Mosquito Nest Eradication (PSN) activities, perform selective abatization or keep larvae-eating fish in places that are difficult to clean to eradicate larvae and do fogging to kill mosquito populations and dissemination of information about DHF through counseling or other activities should be conveyed through health workers with full support from community leaders and adjusted to the level of education of the local population.
