Model simulations of noise pollution due to departures and approaches of passenger aircrafts around Achmad Yani airport Semarang — Indonesia

AchmadYani Airport in Semarang city, Indonesia, is an airport operated by PT AngkasaPura1 which can service 3.2 million passengers annually in 2013. Unfortunately, air transportation can cause numerous environmental damages with serious consequences on population health, such as noise. Noise control of an airport operation can be evaluated its effectiveness through noise contour. As a first step to evaluate the noise control, the objective of this study is to develop a noise contour around AchmadYani Airport by using INM (Integrated Noise Model) and to measure the area of each category based on the Government Ordinance No. 40/2012. In this research, the simulation was conducted on Saturday schedule when the lowest number of aircraft operations was scheduled (44 departures and 44 approaches). According to this study, the area category level I, II, and III using WECPNL (Weighted Equivalent Perceived Noise Level)are 6.774 km
