Abstract

Along with the high demand for electrical energy consumption by the Indonesian people, it will also affect the increase in the construction of power plants in various regions. PLTU Nii Tanasa is one of the power plants located in the Lalonggasumeeto District, Konawe Regency, Southeast Sulawesi. This PLTU uses coal as the main raw material in producing electrical energy. This study analyzed the SO2 content in the exhaust gas of PLTU Nii Tanasa. Based on the results of the study, the concentration of SO2 gas in Nii Tanasa Village was 99.31 g/Nm3. The temperature conditions at the time of sampling were 30ºC and the wind speed was 3.7 km/hour. Meanwhile, point 2 is located in Rapambinopaka Village, the distance from the pollutant source is ± 1 km, the concentration of SO2 gas is 147.69 g/Nm3. The temperature at the time of sampling was 25ºC and the wind speed was 3.7 km/hour. The increase in upper respiratory infection disease that occurs every year is not caused by air pollution, especially SO2 parameters.

Abstract

ABSTRAK Prediksi persebaran gas CO dari sumber transportasi di salah satu jalan arteri primer Kota Kendari menjadi fokus uji coba dalam penelitian ini untuk menentukan konsentrasi polusi udara menggunakan metode gaussian model line source (GMLS). Metode ini merupakan cara unik untuk menganalisis persebaran gas CO yang dikombinasikan dengan metode geographic information system (GIS) kemudian dibandingkan terhadap hasil konsentrasi yang diperoleh dengan baku mutu Peraturan Pemerintah Indonesia No. 22 Tahun 2021 dan visualisasi menggunakan aplikasi GIS. Fokus kajian penelitian dilakukan di Jalan M.T. Hariyono Kota Kendari-Sulawesi Tenggara dengan menghitung volume kendaraan, analisis konsentrasi gas CO, dan pemodelan menggunakan GIS. Berdasarkan hasil pengamatan volume lalu lintas di Jalan arteri primer M.T. Hariyono Kota Kendari menunjukkan bahwa jumlah kendaraan bermotor yang melintas di pagi hari sebanyak 3103 unit/jam (07.00-08.00 WITA), siang hari sebanyak 2,227 (12.00-13.00 WITA), dan sore hari sebanyak 2996 (16.00-17.00 WITA). Jumlah kendaraan tersebut menyumbangkan laju emisi gas CO pada pagi hari sebesar 18,157.06 µg.(m.s)-1, siang hari sebesar  13,982.83 µg.(m.s) -1, dan sore hari sebesar 18,493.33 µg.(m.s) -1. Berdasarkan perhitungan dengan finite length line source (FLLS) turunan dari metode GMLS, persebaran konsentrasi gas CO paling tinggi terletak pada tepi jalan (roadside) sebesar 5,838.84 µg.(Nm3)-1 kondisi pagi hari, 4,496.5 µg.(Nm3)-1 pada siang hari, dan 5,946.96 µg.(Nm3)-1 pada sore hari dengan kondisi kecepatan angin rata-rata 2.1 m.s-1 dan arah angin dari barat laut (315°) ke tenggara (135°). Analisis spasial dengan pemodelan SIG menunjukkan wilayah sebaran dampak dari pencemaran gas CO menuju daerah sekitar ruas jalan raya. Kata kunci: kendari, pencemaran, transportasi, udara ABSTRACT The uniqueness of CO gas analysis from transportation sources on the primary arterial road in Kendari City has become the focus in this study to calculate pollutant concentration using the Gaussian model line source (GMLS) method. This method has combined with the geographic information system (GIS) method then compared the concentration results with the quality standard of Indonesian Government Regulation No. 22 of 2021 and visualization using GIS application. The subject in this study was examined on M.T. Hariyono Street, Kendari City-Southeast Sulawesi Province, Indonesia by calculating vehicle volume, CO gas concentration analysis, and modelling using GIS application. Based on these results, we obtain the traffic of vehicles volume on M.T. Hariyono Street showed that in the morning was 3103 units/hour (07.00-08.00 AM), in the afternoon as many as 2227 units/hour (12.00-13.00 PM), and in the afternoon of 2996 units/hour (16.00-17.00 PM). The number of these vehicles have contributed to the emission rate in the morning of 18,157.06 µg.(m.s)-1, in the noon of 13,982.83 µg.(m.s)-1, and in the afternoon of 18,493.33 µg.(m.s)-1. Based on calculations using the finite length line source (FLLS) derived from the GMLS method, the highest concentration of CO gas is located on the roadside of 5,838.84 µg.(Nm3)-1 in the morning, 4,496.5 µg.(Nm3)-1 in the midday, and 5,946.96 µg.(Nm3)-1 in the afternoon; with an average wind velocity of 2.1 m.s-1 and a wind direction from the northwest (315°) to the southeast (135°). Spatial analysis with GIS produces a distribution area of the impact of CO gas pollution towards the area around the highway. Keywords:  kendari, pollution, transportation, air
