The need for fertilizers continued to increase every year. To fulfill this need, fertilizer industries have to increase their capacities. The process of making fertilizer that uses electricity from natural gas fuel must be converted to coal because of new policy changing. The power plant on the fertilizer industry PT XYZ delivers positive benefits for the industry itself because it can reduce the cost of electricity. On the other hand, the power plants also cause negative effects to the environment, particularly air pollution in the form of particulate matter. The concentration of particulate emitted from PT XYZ’s power plant reach 10282.81 mg/Nm3. These values are above the raw quality of Peraturan Menteri Lingkungan Hidup Nomor 21 Tahun 2008, which are 150 mg/Nm3. Those value are high enough to damage the environment. So, it requires the existence of particulate control device in the form of cyclone and baghouse filters. Based on the results obtained, the dimensions of the cyclone with a body diameter 3.10 m and elevation 30 meters above the ground. As for the baghouse filter, it has 3 compartments with a total of 360 bags equipped with 10 compressed air valves on each row. The energy consumption for cyclone and baghouse filters operation are 649.55 kW. This system is estimated to be able to set aside up to 99.9% of particulate matter in accordance with the concentration of emissions from a power plant compared with the law.
