Background: Dengue Hemorrhagic Fever (DHF) is a viral infection transmitted to humans through the bite of an infected mosquito. The main vectors that transmit the dengue virus are Aedes aegypti and Aedes albopictus. The city with the highest number of dengue cases in Indonesia in 2021 is Depok City with 3,155 cases with an Incidence Rate (IR) of 151.2 cases per 100,000 population. During the last 10 years from 2012-2020, the trend of dengue cases in Depok City tends to increase. Objective: To determine the relationship between climatic factors and population density with the incidence of DHF in Depok City in 2012-2021. Methods: This study uses an ecological study with correlation analysis to see the relationship between climatic factors (temperature, humidity, and rainfall) in the same month (non-time lag), climatic factors with a 1-month lag (time lag 1), and density population with DHF Incidence Rate. Results: The correlation analysis results showed a significant relationship between non-time lag humidity and time lag 1 humidity with DHF Incidence Rate (p = 0.000 and p = 0.000) with the strength of the relationship being positive (r = 0.332 and r-0.451). The results of the multiple linear regression test produce a predictive model with the equation IR DBD = -47.353 + 0.784 (Temperature) + 0.394 (Relative Humidity) + 0.023 (Rainfall). Based on the results of the regression equation, if it is simulated with a combination of the temperature of 26,1oC, humidity of 82.9%, and rainfall of 14.9 mm, there will be an increase in IR of DHF by 10 cases per 100,000 population.
Latar Belakang : Kejadian Demam Berdarah Dengue (DBD) hingga saat ini masih menjadi salah satu masalah kesehatan masyarakat di Indonesia, terutama pada daerah perkotaan seperti Kota Administrasi Jakarta Barat. Variabel iklim berupa suhu udara, tingkat kelembaban, serta curah hujan diketahui berhubungan dengan perubahan jumlah kasus DBD karena faktor-faktor tersebut memengaruhi pertumbuhan dan aktivitas nyamuk Aedes spp. sebagai vektor penular penyakit. Kajian ini dilakukan untuk mengetahui hubungan antara faktor iklim yang mencakup suhu udara, kelembaban udara, serta curah hujan terhadap kejadian Demam Berdarah Dengue (DBD) di Kota Administrasi Jakarta Barat selama periode 2016–2025. Metode : Dalam kajian ini digunakan metode kuantitatif dengan rancangan ekologi time series untuk menganalisis data penelitian. Data yang dipakai merupakan data sekunder berupa jumlah kejadian DBD yang diperoleh dari Dinas Kesehatan Provinsi DKI Jakarta, sedangkan data terkait iklim seperti suhu udara, kelembaban udara, serta curah hujan bersumber dari NASA POWER. Teknik analisis yang diterapkan meliputi analisis univariat serta bivariat, dengan pengujian korelasi menggunakan Pearson atau Spearman berdasarkan hasil uji normalitas masing-masing variabel. Hasil : Temuan kajian ini memperlihatkan jika keterkaitan antara faktor iklim berupa suhu udara serta kelembaban udara terhadap kejadian DBD lebih dominan pada Lag 1 dibandingkan Lag 2. Hubungan negatif yang signifikan ditemukan pada tahun 2021 serta 2023. Di sisi lain, faktor iklim curah hujan memperlihatkan hubungan yang lebih kuat pada Lag 2 daripada Lag 1.
Background: Dengue Hemorrhagic Fever (DHF) remains one of the major public health problems in Indonesia, particularly in urban areas such as the Administrative City of West Jakarta. Climate variables, including air temperature, humidity levels, and rainfall, are known to be associated with changes in the number of DHF cases because these factors influence the growth and activity of Aedes spp. mosquitoes as disease vectors. This study was conducted to determine the relationship between climate factors, namely air temperature, air humidity, and rainfall, and the incidence of Dengue Hemorrhagic Fever (DHF) in the Administrative City of West Jakarta during the 2016–2025 period. Methods: This study employed a quantitative method with a time-series ecological design to analyze the research data. The data used were secondary data consisting of the number of DHF cases obtained from the DKI Jakarta Provincial Health Office, while climate-related data such as air temperature, air humidity, and rainfall were sourced from NASA POWER. The analytical techniques applied included univariate and bivariate analyses, with correlation testing using Pearson or Spearman methods based on the normality test results of each variable.Results: The findings of this study indicate that the relationship between climate factors, specifically air temperature and air humidity, and DHF incidence was stronger at Lag 1 compared to Lag 2. Significant negative relationships were identified in 2021 and 2023. Meanwhile, the climate factor of rainfall demonstrated a stronger relationship at Lag 2 than at Lag 1.
Dengue haemorrhagic fever (DHF) is a disease that frequently affects Indonesia and caused by the dengue virus from infected Aedes aegypti mosquitoes. Climatic factors are known to affect DHF incidence. In 2014-2020, Bogor Regency became the region with the highest DHF deaths in West Java. This study aims to analyze several climatic factors with DHF incidence in Bogor Regency in 2017-2021 using an ecological study design. Using Spearman?s rank correlation coefficient, the results indicate that humidity (r=0,351; p=0,006) and rainfall (r=0,258; p=0,046) have a moderate effect on DHF incidence, while temperature has no effect on DHF incidence (p>0,05).

Dengue hemorrhagic fever (DHF) in South Jakarta Administration City was fluctuating during 2012 - 2016 and in 2016 the incidence rate (IR) was more than tripled from the previous year. This study aims to determine the relationship between climatic factors (rainfall, humidity, temperature) and population density with the incidence rate (IR) of DHF. This study is a time series ecology study and was analyzed by correlation test. Incidence rate (IR) data was obtained from the South Jakarta District Health Office. Monthly climate data was obtained from the Meteorology, Climatology and Geophysics Department of Jakarta. Population density data was obtained from the Central Statistics Department of DKI Jakarta. The results demonstrate that temperature and population density have no significant correlation with dengue incidence rate (p > 0,05). The incidence rate (IR) had a significant correlation with rainfall (r = 0.384; p = 0.002), humidity (r = 0.496; p = 0,000).

Dengue Hemorrhagic Fever (DHF) in Indonesia shows a fluctuating pattern and tends to increase every three years. Depok City ranked second in terms of the highest number of DHF cases in West Java. Environmental factors such as climate, vector density, and population density were suspected to play a role in the spread of this disease. This study aimed to spatially identify the association between environmental factors (temperature, rainfall, humidity, House Index [HI], Larvae Free Index [ABJ], and population density) and DHF incidence in each sub-district of Depok City from 2022 to 2024. This study employed an ecological design with a spatial approach. Secondary data were obtained from the Depok City Health Office, the Depok City Statistics Agency, and NASA. Spatial analysis was conducted using QGIS and GeoDa to calculate spatial autocorrelation (Moran's I and LISA). The mapping results showed a significant increase in DHF cases in 2024. LISA analysis indicated spatial clustering among climate factors, vector indices, population density, and DHF incidence in several sub-districts. It was concluded that there were specific areas that should be prioritized for disease control interventions.
