Abstract
Operasional PLTU di PT. Kaltim Prima Coal menghasilkan emisi pada parameter NOx, SO2, dan TSP. Emisi ini dapat memberikan dampak selain terhadap lingkungan juga terhadap kesehatan. Maka diperlukan simulasi pola penyebaran polutan ke wilayah di sekitar PLTU, untuk mengetahuinya digunakan Software AERMOD. Dalam penelitian telah dianalisis kuantitas emisi NOx, SO2, dan TSP dari cerobong industri batubara dan pola sebarannya. Metode yang digunakan adalah mengolah data meteorologi dengan AERMET, mengolah data elevasi menggunakan AERMAP, dan AERMOD untuk mengestimasi persebaran emisi. Pemodelan dilakukan dalam kurun waktu 2 tahun dengan pembagian periode bulan Mei-November dan bulan Desember-April. Pemodelan juga dilakukan saat kondisi cerobong normal dan start up. Hasil penelitian menunjukkan pola angin pada kondisi atmosfer rata-rata bulan Desember hingga April dan kondisi atmosfer rata-rata pada bulan Mei hingga November dominan ke arah barat. Perhitungan model menunjukkan konsentrasi NOx tertinggi dari sumber titik majemuk pada periode bulan Desember-April sebesar 1116 µg/m3 , SO2 tertinggi sebesar 491,4 µg/m3), dan TSP tertinggi sebesar 47,14 µg/m3 . Semua pencemar jatuh pada koordinat (569827 m; 60723 m). Konsentrasi NOx tertinggi pada periode bulan Mei-November adalah 2152 µg/m3, SO2 tertinggi sebesar 935 µg/m3, dan TSP tertinggi sebesar 90,4 µg/m3 . Semua terjadi pada koordinat (569527 m; 60223 m). Sedangkan perhitungan model kondisi Start Up menunjukkan konsentrasi NOx, SO2, dan TSP tertinggi dari sumber titik majemuk pada periode bulan Desember-April dan periode bulan Mei-November sebesar 9 kali lipat hasil normal dan jatuh pada titik koordinat yang sama. Hasil penelitian menunjukkan sebagian besar debu emisi cerobong jatuh pada area industri.

PT. Kaltim Prima Coal’s PLTU Operational produces emission on NOx, SO2, and TSP parameters. Aside from the environmental impact, this emission also causing a health impact. A pollutant spread pattern simulation is needed to identify the pattern in the area around PLTU, using the AERMOD software. In this research have analyzed the quantity of dust emission from the chimney of the coal industry and the pattern of its distribution. Methods used are processing meteorological data using AERMET, processing elevation data using AERMAP, and estimating the emission spread using AERMOD. The modeling was carried out within 2 years with the distribution in December to April period and in May to November period. Modeling was also done at normal and start-up chimney condition. The results showed that the pattern of wind in December to April and in May to November was dominant to the west. The model calculations showed the highest NOx concentration from multiple point sources in December to April period was 1116 μg/m3, the highest SO2 concentration was 491,4 μg/m3, the highest TSP concentration was 47,14 μg/m3 , all the pollutants fall at coordinates (569827 m; 60723 m). The highest NOx concentration in May to November period was 2152 μg/m3, the highest SO2 concentration was 935 μg/m3, the highest TSP concentration was 90,4 μg/m3 all the pollutants fall at coordinates (569527 m; 60223 m). While the highest NOx concentration of Start Up condition from multiple point sources in December to April period was 9834 μg/m3, the highest SO2 concentration was 4422,3 μg/m3, the highest TSP concentration was 424,2 μg/m3, all the pollutants fall at coordinates (569827 m; 60723 m). The highest NOx concentration in May to November period was 18963 μg/m3, the highest SO2 concentration was 8436 μg/m3 at coordinates, the highest TSP concentration was 816 μg/m3 , all the pollutants at coordinates (569527 m; 60223 m). Most of the dust fell down into industrial area.
