Permasalahan lingkungan dari usaha kegiatan manusia untuk memenuhi kebutuhan hidup, seperti sandang, pangan, papan dan transportasi harus dilakukan penanganan dengan baik. Misalnya seperti pengaruh kegiatan transportasi udara terhadap kondisi kualitas lingkungan setempat seperti kegiatan di Bandara Cilik Riwut Kelurahan Pahandut, Kecamatan Pahandut, Kota Palangka Raya Kalimantan Tengah. Metode penelitian yang digunakan merupakan metode kualitatif dengan analisis data instrumen seperti Sound Level Meter Instrument, Anemometer, GPS, Flight Radar, Google Maps Application & WECPNL Instrument (Weighted Equivalent Continuous Perceived Noise Level) dan pengambilan data dilakukan selama tiga hari sesuai dengan kedatangan dan keberangkatan pesawat. Hasil penelitian dengan analisis WECPNL menunjukkan bahwa tingkat kebisingan di hari ke 2 lebih besar dibandingkan hari ke 3 dan hari ke 3 lebih besar dari hari ke 1 (87,2 > 82,2 > 75,9) dengan nilai rata-rata WECPNL sebesar 81,7. Kebisingan di bandara Cilik Riwut di Kota Palangka Raya Kalimantan Tengah termasuk kebisingan regional tingkat II dan III. Kegiatan yang dapat dilakukan untuk meminimalisir Risiko kebisingan tersebut yaitu dengan melakukan kegiatan rekayasa keteknikan dan menanam vegetasi yang berfungsi mengurangi kebisingan Kata kunci: Bandara, Kebisingan, Lingkungan. The environmental problems of the efforts of human activities to meet the needs of life, such as clothing, food, housing and transportation must be handled properly. For example, such as the influence of air transportation activities on local environmental quality conditions such as activities at Cilik Riwut Airport, Pahandut Village, Pahandut District, Palangka Raya City, Central of Kalimantan. The research method used is a qualitative method with data analysis instruments such as Sound Level Meter Instrument, Anemometer, GPS, Flight Radar, Google Maps Application and WECPNL Instrument (Weighted Equivalent Continuous Percepived Noise) and data collection is carried out for three days in accordance with the arrival and departure of the aircraft. Results of research with WECPNL analysis show that the noise level on the second day is greater than the third day and the third day is greater than the first day (87,2 > 82,2 > 75,9) with score average value is 81,7. Noise at Cilik Riwut airport in Palangka Raya City, Central Kalimantan including regional level II and III noise. activities that can be carried out are carrying out engineering activities and planting vegetation which have the function of reducing noise.
