Abstract

The Bandar Khalipah train station is a class B station which is located very close to
residential areas. This has an impact on the noise level that occurs in the area. This study aims
to analyze train noise using a sound level meter (SLM) and analyze the effect of train operating
time on noise levels. The research method was carried out experimentally. Where noise is
measured using SLM at a distance of 1.5 meters from the train and the location of the SLM
parallel to an adult's ear, namely 1.5 meters. Measurements were taken as much as 14 arrivals
and 14 departures during the week. The result obtained is that the noise that occurs at departure
is 98.4 dB greater than the noise at arrival at 97.7 dB. This is because the sound produced by
the engine occurs due to the combustion process which requires air and heat, resulting in
smoke gas and sound in the chimney. It turns out that the highest noise occurs at 10.42 to 17.22
WIB, with the largest at 98.4 dB at 12.35 WIB. This is due to the greater daytime conditions of
air pressure and temperature. Meanwhile, the lowest noise occurred in the morning and
evening, namely at 6.45 WIB at 80.2 dB. Train noise at the Bandar Khalifah station that occurs
is above the threshold required by the Noise Level Standard in Various Activity Areas
according to the Decree of the Minister of Environment of the Republic of Indonesia, No. 48 of
1996 that is 70 dB.
