Abstract

Pembangkit Listrik Tenaga Uap (PLTU) Suralaya memiliki 7 unit pembangkit dengan total kapasitas 3400 MW berbahan bakar batu bara. Kebutuhan batu bara PLTU Suralaya adalah sebesar 33000 – 35000 ton/hari, setelah beroperasi lebih dari 20 tahun, PLTU Suralaya dihadapkan pada kesulitan pasokan batu bara yang memenuhi kualitas desain pembangkit sehingga konsumsi batu bara berasal dari beberapa pemasok dengan variasi kualitas batu bara. Variasi kualitas batu bara tentu memberikan pengaruh terhadap peralatan pembangkit dan polutan yang dikontribusikan ke lingkungan. Salah satu polutan yang sangat identik dengan PLTU batu bara adalah partikulat dalam bentuk abu terbang yang keluar dari cerobong baik berupa partikulat abu dengan diameter aerodinamik antara 25-40 mikron yang disebut Total Suspended Particulate (TSP) maupun partikulat abu dengan diameter aerodinamik < 10 mikron (PM10). Abu terbang yang diemisikan ke lingkungan adalah sebesar 112.000 s/d 128.800 ton/tahun. Dengan kondisi tersebut, perlu diketahui apakah konsentrasi partikulat ke lingkungan masih memenuhi daya dukung lingkungan. Adapun dalam melakukan pengendalian pencemaran partikulat PLTU Suralaya menggunakan Electrostatic Precipitator (ESP). Metode penelitian yang digunakan adalah dengan melalui tahapan mengumpulkan data sekunder berupa emisi partikulat, data cerobong dan data terkait meteorologi (temperatur, tekanan udara, kelembapan udara, kecepatan, arah angin dan windrose). Pemodelan sebaran emisi dan konsentrasi partikulat dalam radius 15 km diprediksi dengan perangkat lunak AERMOD dan sebagai validasi dilakukan pengukuran partikulat (TSP dan PM10) pada lokasi pemantauan kualitas udara ambien PLTU Suralaya unit 1-7. Kecepatan angin di Suralaya dominan pada 0,5 - 3,6 m/s yang termasuk kategori angin tenang dengan arah menuju selatan pada musim kemarau dan ke arah imur pada musim hujan. Penggunaan batu bara BA memberikan konsentrasi TSP tertinggi dibandingkan dengan batu bara BE dan AO dengan konsentrasi sebesar 22,275 µg/m3 pada 24 jam dengan radius sejauh 4,33 km. PLTU Jawa 9 dan 10 menambah kontribusi pencemar sebesar 0,4% - 5,6% dari kualitas udara ambien saat ini berdasarkan pemantauan triwulanan untuk periode 24 jam. Hasil pemodelan TSP dan PM10 PLTU Suralaya unit 1-7 dalam radius 15 km menunjukkan bahwa perlu ditambahkan 4 titik pemantauan baru berdasarkan besaran kontribusi konsentrasi sebaran TSP dan PM10.
===============================================================================================================================
The Suralaya coal-fired power plant (CPP) has 7 generating units with a total capacity of 3400 MW coal-fired. Suralaya power plant coal demand is 33000 - 35000 tons / day, after operating for more than 20 years, Suralaya CPP is faced with coal supply difficulties that meet the design quality of the plant so that coal consumption comes from several suppliers with variations in coal quality. Variations in the quality of coal certainly have an effect on generating equipment
and pollutants that contribute to the environment. One of the pollutants that is identical to coal-fired power plants is particulate matter in the form of fly ash coming out of the chimney in the form of ash particulate with aerodynamic diameter between 25-40 microns called Total Suspended Particulate (TSP) and ash particulate with aerodynamic diameter <10 microns ( PM10). Fly ash emitted to the environment is 112,000 to 128,800 tons / year. Under these conditions, it is
necessary to know whether the concentration of particulates released into the environment still meets the carrying capacity of the environment. As for controlling the pollution of Suralaya CPP particulates, the power plant installed the
Electrostatic Precipitator (ESP). The research method used is through the stages of collecting secondary data in the form of particulate emissions, chimney data and data related to meteorology (temperature, air pressure, humidity, speed, wind direction and windrose). Modeling of the distribution of emissions and concentrations of particulates within a 15 km radius was predicted using AERMOD software and as a validation, particulate measurements (TSP and PM10) were carried out at ambient air quality in monitoring points of Unit 1-7. Wind speed in Suralaya is dominant at 0.5 - 3.6 m / s, which is included in the category of calm wind with a direction to the south in the dry season and east to the rainy season. The use of BA coal gave the highest TSP concentration compared to BE and AO coal with a concentration of 22.275 µg / m3 at 24 hours with a radius of 4.33 km. Java Power Plant 9 and 10 add pollutant contribution of 0.4% - 5.6%
of the current ambient air quality based on quarterly monitoring for a 24 hour period. The results of the TSP and PM10 modeling of the Suralaya CPP unit 1-7 within a 15 km radius indicate that 4 new monitoring points need to be added based on the contribution magnitude of the TSP and PM10 distribution.
