dc.description.abstractNitrogen dioksida merupakan salah satu polutan udara yang berbahaya dan dapat memberikan dampak negatif terhadap kesehatan manusia serta lingkungan. Metode pengukuran NO2 udara ambien dilakukan dengan metode SNI 7119.2:2017 prinsip yang digunakan gas NO2 dijerap oleh larutan penjerap Griess-Saltzman membentuk senyawa azo dye berwarna merah muda yang stabil dalam 15 menit dan diukur absorbansnya pada panjang gelombang 550 nm. Prosedur validasi meliputi parameter linearitas menghasilkan koefisien korelasi (r) > 0,995. Nilai LOD dan LOQ diperoleh sebesar 0,029 µg/Nm3 dan 0,096 µg/Nm3 , parameter presisi diperoleh nilai %RSD berturut-turut sebesar 0,00%; 0,14%; dan 0,00%, serta parameter akurasi diperoleh nilai %R berturut-turut sebesar 100,20%; 100,02%; dan 100,07%, uji ruggedness memberikan hasil %RSD 0,40077% < 2%, uji robustness diperoleh uji F menunjukan perbedaan yang signifikan. Kadar NO2 di Kantor Setda Kabupaten Lebak yaitu 14,41 µg/Nm3-
dc.description.abstractNitrogen dioxide is a dangerous air pollutant and can have a negative impact on human health and the environment. The method for measuring NO2 in ambient air is carried out using the SNI 7119.2:2017 method, the principle of which is that NO2 gas is adsorbed by a Griess-Saltzman adsorbent solution to form a pink azo dye compound which is stable in 15 minutes and its absorbance is measured at a wavelength of 550 nm. The validation procedure includes linearity parameters producing a correlation coefficient (r) > 0.995. The LOD and LOQ values obtained were 0.029 µg/Nm3 and 0.096 µg/Nm3 , the precision parameters obtained %RSD values respectively 0.00%; 0.14%; and 0.00%, and the accuracy parameters obtained %R values respectively 100.20%; 100.02%; and 100.07%, he ruggedness test gave a %RSD result of 0.40077% < 2%, the robustness test obtained by the F test show a significant difference. The NO2 level at the Lebak Regency Secretariat Office is 14.41 µg/Nm3-
