Air pollution has become a significant environmental issue, particularly in urban and industrial areas. One of the major air pollutants is nitrogen dioxide (NO₂), which is mainly produced by transportation, industrial activities, and fossil fuel combustion. Therefore, this study aimed to analyze NO₂ levels in cold areas (Tanggamus and West Lampung) and hot areas (Bandar Lampung and Metro) in Lampung Province during 2019–2020 using two-way Analysis of Variance (ANOVA). The results showed that NO₂ concentrations in both hot and cold areas ranged from 0–50 µg/m³, indicating that the measured concentrations were still within the “Good” category based on the Air Pollution Standard Index (ISPU) No. 107 of 1997. The ANOVA results for cold areas showed a P-value of <0.05 with an Anderson-Darling (AD) test value of 1.1715, while hot areas showed a P-value of 0.672 with an AD test value of 0.478. These findings indicate that NO₂ concentrations in both hot and cold areas of Lampung Province were still within acceptable air quality standards and may provide baseline information for future air quality monitoring and environmental management strategies.
