Abstract

Suatu keadaan dimana kualitas udara menurun dan terkontaminasi zat, dan apabila zat tersebut berbahaya maupun tidak berbahaya yang menyebebkan gangguan kesehatan manusia disebut pencemaran udara. Salah satu jenis pencemar yang sangat perlu diperhatikan yaitu pencemaran udara akibat pengoperasan mesin seperti Pembangkit Listrik Tenaga Uap (PLTU). PT. X merupakan perusahaan yang menggunakan pembangkit listrik tenaga uap berbahan bakar batu bara dan solar untuk pengoperasian pabrik. Akibat pengoperasian PLTU menghasilkan beberapa gas buang seperti, Nitrogen Dioksida (NO2), Sulfur Dioksida (SO2), Partikulat (PM) dan Merkuri (Hg). Untuk mengetahui pola sebaran dari cerobong asap dapat menggunakan software Aermod View dan diperlukan pengolahan data pada Aermap. Tujuan penelitian ini yaitu analisis data meteorologi untuk input software Aermod View. Data yang diperoleh yaitu data sekunder dari website https://www.ogimet.com/ dan htts://mesonet.agron.iastate.edu/ untuk data meteoroogi yang terdiri dari data arah angin, kecepatan angin, ketinggian angin refrensi, suhu, curah hujan, kelembaban udara, tekanan permukaan dan tutupan awan. Hasil olah data kecepatan dan arah angin bahwa kecepatan angin angin rata "“ rata dan paling banyak terjadi di rentang 3,00 "“ 4,00 m/s, kecepatan minimum terjadi di rentang 1,00 "“ 2,00 m/s serta kecepatan maksimum terjadi di rentang ≥ 7,00 m/sserta arah angin dominan bertiup dari arah timur menuju arah barat.

Abstract

Air pollution can come from natural activities and human activities. One type of pollutant that needs attention is air pollution caused by exhaust fumes from engine combustion and air pollution due to machines such as steam power plants. PT. X is a company engaged in the industrial sector that processes bauxite into alumina. PT. X is an example of an industry that uses coal and diesel-fired steam power plants for its factory operations. As a result of the fuel combustion process produces several exhaust gases, one of which is nitrogen dioxide, into the surrounding air. If the flue gas from the chimney exceeds the quality standard, it can pose a risk to workers and the surrounding community. Therefore, research was conducted on analyzing the distribution of NO2 pollutants from chimneys at PT. X. The data used are primary and secondary. The primary data is in the form of NO2 concentration in ambient air, while the secondary data is in wind direction and speed in one year. The known secondary data is then processed using the wrplot application so that the results are obtained in the form of the distribution of NO2 pollutants in the air. Based on the results of wind speed and direction data processing in Figure 1, it can be seen that the dominant wind direction blows from east to west with 699 occurrences, with wind speeds mostly occurring between 3.00 "“ 4.00 MS. Based on the wind rose above, there is no wind with a speed of less than 0.5 m/s or a calm wind. The minimum speed occurs in the range 1.00 "“ 2.00 m/s and the maximum speed occurs in the range ≥ 7.00 m/s.
