    Abstract
    The analysis has been performed to determine sulfur dioxide (SO2) levels in ambient air at Dinas Lingkungan Hidup Provinsi Sumatera Utara. To determine the level of sulfur dioxide in the ambient air, it was performed by the pararosaniline method and then the asorbance was measured using a UV-Visible Spectrophotometer at a wavelength of 550 nm then calculation were carried out on the samples and obtained varying results, namely in the ambient air sample with code 2021/UA/02/37 sulfur dioxide level of 74,0164 μg/m3; in the ambient air sample with code 2021/UA/02/38 sulfur dioxide level of 98,6219 μg/m3; and in the ambient air sample with code 2021/UA/02/39 sulfur dioxide level of 104,7987 μg/m3. Based on The Government Regulation of the Republic of Indonesia Number 22 of 2021 regarding Implementation of Environmental Protection and Management, the maximum concentration of sulfur dioxide (SO2) in ambient air for 1 hour is 150 μg/m3. This indicates that the tested air samples met the national ambient air quality standards.
     
    Telah dilakukan analisis untuk menentukan kadar sulfur dioksida (SO2) di udara ambien di Dinas Lingkungan Hidup Provinsi Sumatera Utara. Untuk menentukan kadar sulfur dioksida di udara ambien dilakukan dengan metode pararosanilin lalu diukur absorbansinya menggunakan Spektrofotometer UV-Visible pada panjang gelombang 550 nm lalu dilakukan perhitungan pada sampel dan diperoleh hasil yang bervariasi, yaitu pada sampel udara ambien dengan kode 2021/UA/02/37 kadar sulfur dioksida sebesar 74,0164 μg/m3; pada sampel udara ambien dengan kode 2021/UA/02/38 kadar sulfur dioksida sebesar 98,6219 μg/m3; dan pada sampel udara ambien dengan kode 2021/UA/02/39 kadar sulfur dioksida sebesar 104,7987 μg/m3. Berdasarkan Peraturan Pemerintah Republik Indonesia No. 22 Tahun 2021 tentang Penyelenggaraan Perlindungan dan Pengelolaan Lingkungan Hidup, kadar maksimum sulfur dioksida (SO2) di udara ambien selama 1 jam adalah 150 μg/m3. Hal ini menunjukkan bahwa sampel udara ambien yang dianalisis memenuhi baku mutu udara ambien nasional.
