Abstract
Noise is one of the environmental health problems in big cities. The 1988 WHO report as submitted by the Indonesian Health Service (1995), states that 8% - 12% of the world's population has suffered from the effects of noise. The activity of residents of the city of Bogor a suburb of the capital city of Jakarta in Indonesia is relatively high. Along with the economic development in the city of Bogor, the number of motorized vehicles operating both private and public vehicles has also increased. The purpose of this study was to determine the average speed of motorized vehicles that pass through the Dramaga highway, especially in front of the Karya Baki Pratiwi Hospital, and also to determine the level of noise generated due to the speed of motorized vehicles. The method used in this study is a quantitative method by calculating the number of vehicles and the average speed of vehicles and data analysis. The data taken is vehicle speed data every 15 minutes and noise levels using a Sound Level Meter (SLM). In this study, three SLMs were used which would be placed at three points. The results showed that the speed of the vehicle affects the noise level which is quite significant. The results of data analysis show that the effect of speed on noise is 24%, where the equation is as follows, y=69.505 – 0.395x1 +0, 148x2 + 0.535x3. This equation means that if there is no decrease in motorcycle speed, light vehicle speed, and heavy vehicle speed, the noise level in SLM1 is 69.505 dBA. However, if there is an increase in the number of light vehicles by 0.148, a decrease in the number of motorcycles and large vehicles is obtained by 0.14, the noise level will increase by 0.395 dBA.
