Abstract
Pencemaran udara memiliki dampak yang merugikan, baik bagi alam maupun kesehatan manusia akibat menurunnya kualitas udara, salah satunya dapat diketahui dengan melihat persebaran partikel aerosol. Aerosol merupakan partikel berukuran 10-9–10-4 μm di udara yang berpengaruh terhadap kualitas udara dan iklim. Untuk monitoring penurunan kualitas udara akibat persebaran aerosol dapat dilakukan dengan memperhitungkan ketebalan persebaran aerosol, salah satunya menggunakan citra MODIS dengan algoritma SARA (Simplified highresolution MODIS Aerosol Retrieval Algorithm) untuk mendapatkan nilai AOD (Aerosol Optical Depth) pada wilayah Surabaya. Persebaran AOD diperhitungan dengan memperhatikan aspek meteorologi dan penggunaan lahan serta dilakukan validasi terhadap SPM dan produk aerosol pada MODIS Level 2. Hasil dari penelitian didapatkan hasil persebaran AOD dengan nilai tertinggi sebesar 1,794μm pada bulan Mei dengan curah hujan sebesar 7,0 mm/days pada Kecamatan Dukuhpakis. Sedangkan nilai AOD terendah sebesar 0,494μm terjadi pada bulan Januari dengan curah hujan sebesar 21,0 mm/days pada wilayah Benowo. Dari hasil uji akurasi perhitungan persebaran AOD pada Kota Surabaya termasuk kedalam kategori tinggi yaitu sebesar 86%. Sedangkan pada uji akurasi dengan data SPM memiliki tingkat korelasi sedang yaitu sebesar 42% dengan nilai RMSE sebesar 0,077μm. Persebaran AOD sangat dipengaruhi oleh musim hujan, dimana dari perhitungan korelasi memiliki tingkat hubungan yang sedang yaitu 0,545 dan pengaruh aspek pola angin sebesar 0,391 serta pengaruh aspek penggunaan lahan sebesar 0,190. Sehingga dalam penentuan kualitas udara dapat dilihat oleh pengaruh persebaran AOD, dimana persebaran AOD akan rendah jika berlawanan dengan pola angin dan memiliki curah hujan tinggi serta rendahnya penggunaan lahan.

Air pollution has a detrimental effect on both nature and human health due to a decrease in air quality, one of which can be seen by looking at the distribution of aerosol particles. Aerosol is a particle in the air sized 10-9–10-4 μm which effects human health, air quality, and climate. In monitoring air quality decline that affected by aerosol spread can do with calculate aerosol depth distribution, one of them is using SARA algorithm (Simplified highresolution MODIS Aerosol Retrieval Algorithm) to get AOD (Aerosol Optical Depth) spread value in Surabaya City. Spreading of AOD is calculated with observe meteorology and land use aspect. And then validate to SPM and aerosol product in MODIS Level 2. From this research obtained Spreading of AOD with maximum value amounting to 1.794μm in May with rainfall 7.0 mm/days at Dukuhpakis district. While minimum AOD value amounting to 0.494μm in January with rainfall 21.0 mm/days at Benowo district. From the result of accuration test calculation Spreading of AOD at Surabaya City includes into the high category that is 86%. While the accuracy test with SPM data has midle correlation relationship level that is 42% with RMSE value amounting to 0.077μm. Spreading of AOD is very impacted by rainfall, where is from correlation calculate has midle correlation relationship that is 0.545 and winds pattern impact amounting to 0.391μm, and land use impact amounting 0.190. So that in determination air quality could seen by Spreading of AOD impact, where it will low if opposite with wind pattern and have high rainfall and low land use.
