The Effect of Vegetation in Reducing Traffic Noise Around the Selagalas Green Open Space

This study aims to analyze the effect of vegetation in reducing traffic noise around the Selagalas Green Open Space in Mataram City. The research method employed is a quantitative descriptive approach, with primary data collection consisting of noise level measurements using a Sound Level Meter, vegetation density analysis, and visitor perceptions gathered through questionnaires. Noise measurements were taken at 15 observation points in the morning and afternoon, and then analyzed using equivalent noise values (Leq). The spatial distribution of these measurements was mapped using the Inverse Distance Weighted (IDW) interpolation method. The results showed that the average noise level in Selagalas Green Open Space was 57.31 dB(A), which exceeded the noise quality standard for green open spaces. High-density vegetation, especially broad-canopied trees, was able to reduce noise levels by up to 19.91 dB(A) with a reduction effectiveness of 10.35%. Visitors' perceptions of the Selagalas RTH were positive and quite satisfactory. The conclusion of this study reveals that vegetation plays a crucial role in mitigating noise and enhancing the comfort of the urban environment.
