Mapping of Residential Noise Levels Along Railway Lines: A Case Study of Jl. Haur Jaya, Bogor City

Abstract

ABSTRACT:

The occurrence of urban sprawl is caused by the need to accommodate the increasing urban population, many workers work in cities and have a place to live and other living space needs. They travel across districts and cities, the majority of workers, they choose to become commuter workers[3] . If seen from the commuter data from Bogor Regency, it is ranked 4th, the public transportation means that commuters consider the most effective is the train. Then the discussion of this writing is more about the mapping of residential noise that intersects with the tracks from the railroad tracks on Jl Haur Jaya, and Jl. Bubulak, Bogor City. Sampling measurements at the location using the SANFIX type WT85B Sound Level Meter instrument with a measurement time of 24 hours were carried out in 4 times at 4 measurement points, for 10 minutes with an interval of 5 seconds so that 120 data were produced, then entered into the analysis stage the data was processed to obtain data equivalent noise level using the following formula: Leq = 10 log 1/n ∑Tn.100.1 Ln dB(A), Nearly 50% of the noise level in 2 settlement points must be reduced to achieve a noise level of 55.0 dBA. It is recommended to reduce noise levels by using artificial barriers or plant barriers so that the health of settlements in this area becomes of higher quality.
