Abstract: Aktivitas industri berkontribusi terhadap pencemaran udara, salah satunya adalah penggunaan boiler, dengan jenis pencemar diantaranya adalah NOx. Penelitian ini bertujuan mengidentifikasi pola dispersi NOx dari cerobong boiler pada aktivitas industri pakan ikan dan udang, dan menganalisis faktor yang memengaruhi dispersi emisi. Pemodelan dilakukan menggunakan perangkat lunak AERMOD View, dengan data emisi boiler hasil pengukuran tahun 2024 serta data meteorologi harian dari NASA POWER dan Copernicus ERA5. Hasil penelitian menunjukkan bahwa konsentrasi NOx di udara ambien maksimum sebesar 13,93 µg/m³ pada bulan April dengan jarak 0,18 km dan 23,5 µg/m³ pada bulan Oktober dengan jarak 1,46 km dari sumber emisi cerobong boiler. lokasi sebaran konsentrasi maksimum mencakup lahan perkebunan Jagung dan Karet di daerah Cibatu. Hasil perbandingan dengan pengukuran di lapangan diagram wind rose menunjukkan pola dispersi konsisten pada April, sedangkan Oktober mengalami variasi arah akibat perubahan kecepatan angin. Konsentrasi di area pemukiman, termasuk dekat fasilitas kesehatan, masih di bawah baku mutu PP No. 22 Tahun 2021.
Industrial activities contribute to air pollution, one of which is the use of boilers, with the type of pollutant being NOx. This study aims to identify the NOx dispersion pattern from boiler chimneys in fish and shrimp feed industries, and analyze the factors that influence emission dispersion. Modeling was carried out using AERMOD View software, with boiler emission data measured in 2024 and daily meteorological data from NASA POWER and Copernicus ERA5. The results showed that the maximum NOx concentration in ambient air was 13.93 µg/m³ in April at a distance of 0.18 km and 23.5 µg/m³ in October at a distance of 1.46 km from the boiler chimney emission source. The distribution location of the maximum concentration includes corn and rubber plantations in the Cibatu area. The results of the comparison with field measurements of the wind rose diagram showed a consistent dispersion pattern in April, while October experienced variations in direction due to changes in wind speed. Concentrations in residential areas, including near health facilities, were still below the quality standards of Government Regulation No. 22 of 2021.
