Abstract
Along with the increasing needs of people inMakassar city for the mode of transportation, the number of thegrowth of motor vehicles that operate on the road becomes largerthan the growth of the number of roads built. This has causedsome problems in the transportation sector. In addition tocongestion problems, problems arise from road surface damagedue to increasing traffic loads that must be borne by the roadsurface. To anticipate this, some strategic streets in the city ofMakassar then designed by using a rigid pavement that hasgreater strength in carrying the burden. Another problem thatarises from the growing number of motor vehicles that operateon the road is greater than the growth of the number of roadsbuilt is the higher levels of noise pollution or traffic noise. Noise issourced from the sound of a vehicle engine and the frictionbetween the vehicle tire and the road surface. So that roads withrigid surface pavement surfaces that have a rougher surfacetexture, potentially lead to higher noise levels. This study aims todetermine how much noise levels that occur in roads that userigid pavement in the city of Makassar. The road segments, suchas Jl. Abd. Dg. Sirua, Jl. Batua Raya and Jl. Adhyaksa. The toolused to measure traffic noise is the Sound Level Meter (SLM).The survey was conducted for 1 day for each of the roadsegments reviewed. The data taken are the level data of flatnessof road surface, vehicle speed data and traffic noise level data.Data processing is done by analyzing the relationship between thefactors that affect the noise with the noise level that occurs on theroad with rigid pavement. The results of this study are expectedto provide information about how big the effect of vehicle speedon the noise level that arises on the road with rigid pavement.Keyword--Noise; speed of vehicle; Rigid Pavement

Summary
Salah satu penyebab permasalahan transportasi di Kota Makassar adalah pertumbuhan kendaraan yang begitu pesat. Angka tersebut menunjukkan pertumbuhan kendaraan tidak sebanding dengan peningkatan jaringan jalan, dimana hal ini tentu saja menimbulkan masalah di ruas jalan Kota Makassar. Dari hasil penelitian terdahulu diketahui bahwa tingkat kebisingan yang ada di ruas jalan protokol wilayah kota Makassar sudah mencapai 74 dB [1], nilai tersebut telah melebihi standar baku mutu yang berlaku. Perkerasan kaku dirancang untuk mengantisipasi beban lalu lintas yang berat, hal ini dilakukan sebagai salah satu upaya untuk mengantisipasi masalah kerusakan permukaan jalan yang ditimbulkan karena tidak sebandingnya pertumbuhan jalan dengan pertumbuhan jumlah kendaraan bermotor yang beroprasi. Beberapa ruas jalan yang menggunakan perkerasan kaku di Kota Makassar teridentifikasi secara visual memiliki lalulintas yang padat dan lingkungan yang padat penduduk. Hasil penelitian diharapkan bisa memberikan informasi tentang seberapa besar pengaruh kecepatan kendaraan terhadap tingkat kebisingan yang terjadi pada ruas jalan yang ditinjau, sehingga jika misalnya diketahui tingkat kebisingan yang terjadi melebihi ambang batas yang diizinkan, kemudian berikutnya dapat dilakukan tindakan lanjutan untuk meredam kebisingan yang terjadi
