Abstract
Demam Berdarah Dengue (DBD) merupakan penyakit menular yang disebabkan oleh virus dengue dan ditularkan melalui nyamuk Aedes aegypti dan Aedes albopictus. Kota Surabaya, sebagai ibu kota Jawa Timur, mencatat peningkatan kasus DBD dari tahun ke tahun. Faktor-faktor seperti kepadatan penduduk, mobilitas penduduk, urbanisasi, perubahan iklim, dan kondisi lingkungan diduga memengaruhi penyebaran DBD. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang memengaruhi kasus DBD di Kota Surabaya menggunakan pendekatan regresi spasial. Variabel independen yang digunakan meliputi Angka Bebas Jentik (ABJ), Kepadatan Penduduk, Cakupan PHBS, dan Rasio Fasilitas Kesehatan. Setelah dilakukan pemodelan awal dengan regresi OLS, uji Lagrange Multiplier menunjukkan adanya autokorelasi spasial, sehingga digunakan model regresi spasial yaitu Spatial Lag Model (SAR), Spatial Error Model (SEM), dan Spatial Autoregressive Combined Model (SARMA). Model SARMA dipilih sebagai model terbaik dengan nilai AIC sebesar 187,58 dan R2 sebesar 0,676. Dalam model SARMA, variabel ABJ, Kepadatan Penduduk, dan PHBS memiliki pengaruh negatif signifikan terhadap prevalensi DBD, sementara Rasio Fasilitas Kesehatan tidak termasuk dalam model akhir. Analisis spasial lanjutan menggunakan Local Indicators of Spatial Association (LISA) menunjukkan bahwa Kecamatan Tandes dan Pakal termasuk klaster High-High, yaitu wilayah dengan prevalensi DBD tinggi yang berbatasan langsung dengan wilayah tinggi lainnya. Temuan ini menegaskan bahwa penyebaran DBD di Surabaya tidak bersifat acak, tetapi membentuk pola klaster yang signifikan secara statistik spasial.

Dengue Hemorrhagic Fever (DHF) is a communicable disease caused by the dengue virus and transmitted by Aedes aegypti and Aedes albopictus mosquitoes. Surabaya, the capital city of East Java Province, has recorded an increasing trend in dengue cases over the years. Several factors, such as population density, human mobility, urbanisation, climate change, and environmental conditions are presumed to influence the spread of dengue. This study aims to analyze the determinants of dengue prevalence in Surabaya using a spatial regression approach. The independent variables include the Larvae Free Index (ABJ), population density, coverage of Clean and Healthy Living Behaviour (PHBS), and the ratio of health facilities. Following an initial Ordinary Least Squares (OLS) model, the Lagrange Multiplier test indicated significant spatial autocorrelation, prompting the use of spatial regression models, namely the Spatial Lag Model (SAR), Spatial Error Model (SEM), and Spatial Autoregressive Combined Model (SARMA). The SARMA model was identified as the best-fitting model, with an AIC value of 187.58 and an R² of 0.676. In the SARMA model, ABJ, population density, and PHBS were found to have significant negative effects on dengue prevalence, while the health facilities ratio was excluded from the final model. Further spatial analysis using Local Indicators of Spatial Association (LISA) revealed that Tandes and Pakal districts formed High-High clusters areas with high dengue prevalence surrounded by similarly high-prevalence neighbours. These findings indicate that the spatial distribution of dengue in Surabaya is not random but exhibits statistically significant clustering patterns.
