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.

Exposure to fine particulate matter (PM2.5) is associated with mortality for cardiovascular and pulmonary disease. PM2.5 concentration increased in accordance with motor-vehicle quantity. This study aims to estimate the risk of PM2.5 exposure among workers as population at risk in Depok Integrated Terminal. The risk quotient is estimated using EHRA methodology. In order to estimate the risk, outdoor ambient air PM2.5 was observed at 3 points area (observed in the morning, afternoon, and evening at each point), and also individual anthropometry and activity pattern had been surveyed among 63 respondents. Average PM2.5 ambient concentration is 61,67 µg/m3 . The result of realtime and lifetime assessment showed that workers in general had non carcinogen risk (RQ>1) with general potential average dose of 0,005 mg/kg.day and 0,0106 mg/kg.day. Based on occupation type, both realtime and lifetime assessment showed that all occupation type had high risk quotient. The risk management that can be done is by decreasing the concentration to the safest, 23 µg/m 3 or by limiting the time of exposure.

Dengue merupakan penyakit infeksi virus yang ditularkan melalui nyamuk Aedes aegypti dan menjadi tantangan kesehatan masyarakat di Indonesia. Pada tahun 2024, Kota Depok mencatat 5.040 kasus dengue (IR 266/100.000 penduduk) dengan 13 kematian (CFR 0,25%), jauh melebihi target nasional (IR ≤10/100.000). Penelitian ini bertujuan untuk menganalisis faktor risiko kejadian dengue secara spasial di Kota Depok tahun 2024 dengan menggunakan pendekatan mix-method. Penelitian ini menggunakan desain cross-sectional untuk pendekatan kuantitatif dengan data sekunder dan pendekatan explanatory untuk kualitatif melalui wawancara mendalam. Analisis spasial dilakukan menggunakan perangkat lunak QGIS dan GeoDa. Variabel yang dianalisis meliputi jenis kelamin, usia, kepadatan penduduk, perilaku hidup bersih dan sehat (PHBS), serta angka bebas jentik (ABJ). Kasus dengue menunjukkan pola spasial mengelompok dengan autokorelasi spasial pada variabel-variabel yang diteliti. Model Spatial Error Model (SEM) memberikan hasil terbaik dengan nilai AIC terendah (657,88) dan R² sebesar 0,276. Efek spasial eror sebesar 37,4% menunjukkan pengaruh dari wilayah sekitar terhadap penyebaran kasus dengue. Kepadatan penduduk ditemukan sebagai variabel signifikan yang berhubungan dengan kejadian dengue. Wilayah prioritas untuk intervensi meliputi Kelurahan Bedahan, Rangkapan Jaya Baru, Depok Jaya, Mampang, dan Cisalak. Pendekatan spasial efektif dalam mengidentifikasi wilayah risiko tinggi dengue dan variabel yang memengaruhi penyebarannya. Disarankan agar intervensi dengue lebih difokuskan pada wilayah dengan kepadatan tinggi, peningkatan edukasi PHBS, integrasi analisis spasial dalam perencanaan program, serta koordinasi lintas sektor. Strategi ini diharapkan dapat meningkatkan efektivitas pengendalian dengue yang berbasis data dan wilayah.
Dengue is a viral infection transmitted by Aedes aegypti mosquitoes and remains a significant public health threat in Indonesia. In 2024, the city of Depok reported 5,040 dengue cases (IR 266/100,000 population) and 13 deaths (CFR 0.25%), far exceeding the national target of IR ≤10/100,000. This study aims to spatially analyze the risk factors associated with dengue incidence in Depok City in 2024 using a mixed-methods approach. A cross-sectional ecological design was used for the quantitative component, supported by secondary data, while the qualitative component followed an explanatory design through in-depth interviews. Spatial analysis was conducted using QGIS and GeoDa. The variables analyzed included gender, age, population density, household-level Clean and Healthy Living Behavior (PHBS), and larva-free index (ABJ). Dengue cases exhibited a clustered spatial pattern with spatial autocorrelation across the studied variables. The Spatial Error Model (SEM) yielded the best performance with the lowest AIC (657.88) and R² of 0.276. A spatial error effect of 37.4% indicated that neighboring areas influence dengue transmission. Among all variables, population density was significantly associated with dengue incidence. Priority intervention areas identified were Bedahan, Rangkapan Jaya Baru, Depok Jaya, Mampang, and Cisalak sub-districts. A spatial approach is effective in identifying high-risk areas and key factors influencing dengue transmission. It is recommended that dengue prevention programs prioritize high-density areas, strengthen PHBS education, integrate spatial analysis into health program planning, and enhance cross-sector coordination. These strategies are expected to improve the effectiveness of dengue control efforts based on spatial and epidemiological data.
