However, in line with the 2020 Covid-19 pandemic, it has an impact on the decrease in the number of motorized vehicles on the highway. The density of motorcycles has a significant effect on noise, from all analysis calculations, the largest equation is obtained on the fourth day of the study, the second point (Sound Level Meter 2), with a contribution of 32.42%. Obtained the calculation below, y = 63.36 + 0.002x1. This equation means that if there is no decrease in motorcycle density, the noise level in SLM2 is 63.36 dBA. If there is a motorcycle density also has a significant effect on noise. The second largest equation was obtained on the third day of research at the third point (Sound Level Meter 3) with a contribution of 36.21% based on the equation calculation below, y = 60.24 + 0.001x1. The meaning of the above equation is that if there is an increase in the density of the motorcycle, the noise in the SLM3 is 60.24 dBA. The Covid-19 pandemic that has hit the world, Indonesia is also getting its effects, especially the very large Bogor district. The rapid spread of Covid-19 has changed the pattern of life for the people of Bogor, especially students who initially go to school every morning, now go to school and study online.

Of course it produces new problems that may still be underestimated, the problem is noise (Syaiful, S, Mudjanarko, SW, 2019; Syaiful S, Akbar L, 2015; Syaiful S, 2015). So that the noise generated by these vehicles is considered normal for road users and local residents, but actually there are public facilities around the highway that are harmed by noise which will greatly disturb the school students such as students who need peace in the learning process (Syaiful S, Wahid N, 2020). Each motorized vehicle produces a variety of noise. This noise has a considerable impact on the tranquility of the area that is directly in contact with the highway. Therefore, setting the distance between the main school building and the road must be taken into account, for the sake of realizing the comfort of the school students (Syaiful S, Thamrin T, 2016; Karimah H, Akbardin J, 2019; Ganda SF, Moetriono H, Mudjanarko SW, 2019) . The noise disturbance studied and observed is limited to noise source level disturbances which are not disturbances of air pollution levels or waste pollution. The sample studied can represent daily activities carried out at 06.00 - 18.00 WIB. The day that represents each educational activity for four days, namely Saturday, Sunday, Monday, Tuesday means the day that represents each activity. Definition of Highway
