چکیده
Penelitian ini bertujuan untuk menguji model AERMOD dalam memprediksi sebaran PM10 di udara ambien kawasan PT Semen Padang. Lokasi penelitian sebanyak 32 titik berdasarkan 8 arah mata angin dengan jarak 0,5 km, 1 1,5 km dan 2 dari Pengukuran menggunakan EPAM 5000 Real Time Particulate Air Monitor dilanjutkan pemetaan software Surfer 11. Waktu pengukuran dibagi menjadi 4 shift, yaitu shift (00.00 – 05.59 WIB), (06.00 11.59 3 (12.00 17.59 WIB) (18.00 23.59 WIB). Pengambilan data meteorologi (temperatur udara, tekanan kelembapan, kecepatan angin) alat Meteorological Station PCE-FWS-20 input pada AERMET, prediksi View 8.9.0. Hasil menunjukkan konsentrasi berkisar antara 21,0 79,0 µg/m3 rata-rata 24 jam sebesar 41,7 µg/m3. Konsentrasi 3,5 sampai 68,0 10,6 Jika dibandingkan baku mutu Peraturan Pemerintah No. 22 Tahun 2021 tentang Penyelenggaraan Perlindungan Pengelolaan Lingkungan Hidup, lokasi 11 koordinat S 0°56'52.46" E 100°27'41.88" Barat Padang tidak memenuhi mutu. Model mendekati ideal atau dikatakan sempurna Timur Laut karena elevasi yang lebih tinggi sumber emisi merupakan dominan siang hari.ABSTRACTThis study aims to test the in predicting distribution of ambient air area. The research locations were points based on eight cardinal directions with a radius 0.5 1.5 and from measurement using Real-Time followed by mapping software. time is divided into four shifts, namely retrieval (air temperature, pressure, humidity, wind speed direction) for prediction 8.9.0 results showed that concentration ranged 21.0 79.0 g/m3 24-hour average 41.7 g/m3. 3.5 - 68.0 10.6 When compared quality standard Government Regulation no. concerning Implementation Environmental Protection Management, location coordinates at distance west does not meet standards. close or said be perfect, East Northeast because higher elevation emission source dominant direction during day.
