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 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 Haemorrhagic Fever (DHF) is an infectious disease transmitted by Aedes aegypti and Aedes albopictus mosquitoes who infected with dengue virus. DHF have been affecting more than 100 tropical and sub-tropical countries in the world. Around 1.8 billion (more than 70%) of the population at risk of dengue fever worldwide live in countries of Southeast Asia and the Western Pacific Region, including Indonesia. In 2016, DKI Jakarta was assigned the status of outbreak of DHF, with a total of 22,697 cases and an incidence rate (IR) of 220.8 per 100,000 population. West Jakarta is one of the regions with the highest DHF incidence rate compared to other cities in DKI Jakarta. This study aims to determine the spatial analysis of the incidence of dengue in West Jakarta in 2015-2019 by considering several factors such as demographics, climate, and larval free index. This study uses an ecological study with a spatial analysis approach and correlation analysis to see the strength of the relationship between the incidence of DHF with factors of population density, climate, and larvae free index. Spatially the incidence of DHF tends to occur in areas with high density and low larvae free index. Statistically, correlation analysis shows that there is a significant relationship between population density, air humidity, and rainfall with the incidence of DHF. Meanwhile, there is no significant correlation between the air temperature and larvae free index with the incidence of DHF in West Jakarta. Result shows that from 56 urban villages in West Jakarta, there are 53 urban villages that are categorized as high vulnerability, and 3 urban villages categorized as medium vulnerability. The high problem of dengue cases in West Jakarta makes the authorities should increase efforts or planning and optimize community empowerment in eradicating dengue cases. Keywords: Dengue Haemorrhagic Fever (DHF), Population Density, Climate, Larvae Free Index, Spatial Analysis.
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.
