Abstract

The rise of construction projects and population growth, followed by the expansion of industry and any other sectors such as housing estate, offices, and transportation, can lead to not only economic growth but also negative impacts such as air pollution, including nitrogen dioxide (NO2) pollutants. According to KEP-45/MENLH/10/1997, air pollution can be determined by The Pollutant Standards Index (PSI). The statistical analysis result employing the multivariate ANOVA test with the Anderson-Darling method showed the impact of NO2 concentrations on four location points over two years. Meanwhile, the data result of PSI revealed a high level of ambient air NO2 in Lampung Barat Regency, particularly at the monitoring point of offices. On the other hand, in Way Kanan Regency, the level of ambient air NO2 tends to be safe and secure at the monitoring point of industry and transportation. The factor of sampling location and technique (stage 1: dry season, stage 2: rainy season) did not give a significant effect on the NO2 level due to a p-value ≥ 0,05. However, the sampling point (of monitoring) influenced the NO2 level for p-value ≤ 0,05 in Lampung Barat and Way Kanan Regency in 2019-2020 which was still claimed as safe and secure based on PP No. 41 in the Year 1999, which sets the required limit at 100 g/m3.

Abstract

Pencemaran udara oleh sulfur dioksida (SO2) dapat berasal dari sumber suatu kawasan terutama sektor transportasi, perindustrian, pemukiman, dan perkantoran yang berkaitan dengan aktifitas manusia. Pencemaran udara dapat ditentukan dengan ISPU (Indeks Standard Pencemar Udara) yang berdasarkan KEP45/MENLH/10/1997. Berdasarkan hasil perhitungan didapatkan ISPU SO2 pada empat titik lokasi pemantuan di Kabupaten Lampung Barat dan Way Kanan pada tahun 2019 dan 2020 termasuk dalam kategori yang aman dan tidak berbahaya dengan nilai ISPU secara keseluruhan di bawah 50. Rata-rata konsentrasi SO2 yang dihasilkan pada tiap titik pemantauan di Kabupaten Lampung Barat dan Way Kanan pada Provinsi Lampung menurut PP Nomor 41 Tahun 1999 masih berada di bawah ambang batas. Berdasarkan hasil analisis statistik menggunakan ANOVA multivariat, nilai p-value pada titik sampling (pemantauan), pengambilan sampling dan lokasi menunjukkan lebih dari 0,05 yang artinya tidak berpengaruh signifikan terhadap kadar SO2 di Kabupaten Lampung Barat dan Way Kanan pada tahun 2019 dan 2020. Kata kunci: SO2, ISPU, Lampung Barat, Way Kanan.
