## Abstract
Abstract This research aimed to analyze the noise reduction based on the noise barrier along the Makassar-Parepare railway. The measurement was conducted on Makassar-Parepare line, which consists of 4 types of areas. Six of the observation points are in residential areas, 1 point in commerce area, 1 point in the green open space area, and 1 point in the station area. Each region has 6 measurement points. So that the whole measurement points are 54 measurement points. The noise level measurement was conducted using simple SLM (sound level meter) placed at 3 meters from the side of the road with a height of 1.2 meters from the road surface and omitted the background noise by using windscreen from the SLM. Measurements were operated every 10 minutes for four-time intervals which are 06.00-09.00, 09.00-14.00, and at 14.00-17.00. The research result shows the settlement areas consisting of 36 measurement points, in which 69% has exceeded the quality standard, and 31% are still below the standard. For the green open space area which includes six measurement points, 17% has exceeded the quality standard, and 83% are still below the standard. For the commerce area and stations which consist of 6 measurement points, 100% of the areas are still below the standards. The noise barrier design could reduce the noise level 5.0 until 7.7 dB.
