Abstract
Pada tahun 2021, Surabaya meraih penghargaan di ASEAN ESC pada kategori Udara Terbersih Kota Besar, na-mun pada Juni 2022, Surabaya menduduki 10 kota dengan kua-litas udara terburuk di Indonesia. Oleh karena itu, diduga kua-litas udara di Surabaya mengalami fluktuasi sehingga perlu di-lakukan analisis peramalan. Pada penelitian ini akan digunakan model VARIMA untuk meramalkan kualitas udara di Surabaya menggunakan PM10, NO2, dan O3. Hasil yang didapatkan ada-lah pada tanggal 10 April hingga 10 Oktober, konsentrasi PM10 berada di kategori baik hingga sedang, namun beberapa kali masuk pada kategori tidak sehat, yaitu pada tanggal 12 April, 31 Mei, 2 Juni dan tertinggi berada pada tanggal 3 Juni. Kon-sentrasi NO2 berada pada kategori baik hingga sedang, namun pada tanggal 31 Mei berada pada kategori tidak sehat. Konsen-trasi O3 berada pada kategori baik. Peramalan kualitas udara di Surabaya pada tanggal 11 Oktober hingga 25 Oktober 2022 menggunakan model VARIMA (3,1,0) menunjukkan bahwa konsentrasi PM10 berada pada kategori sedang sedangkan kon-sentrasi NO2 dan O3 berada pada kategori baik, sehingga ting-kat kualitas udara masih dapat diterima pada kesehatan manu-sia, hewan, dan tumbuhan.
