TRAFFIC DENSITY DUE TO MOTORCYCLE NOISE DURING THE PANDEMIC COVID-19

The density of motorized vehicles, especially motorcycles on the highway, is getting higher. 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.

Bogor Regency has an economic growth rate including the highest among cities and other districts around the Jakarta Capital Region. Regarding the condition of the vehicle population in Bogor district, the number of motorized vehicles in 2017 and 2018 experienced a growth of between 2% and 12%. In contrast to the growth rate of vehicles, the road growth rate is only 0.1% per year. Nurul Hidayah Mosque is located on Jalan Salabenda, the object of the author's research to find out how much influence the sound of motorized vehicles has on worship activities around the Nurul Hidayah mosque. In public transport car speed, motorcycle speed, and private car speed do not have a significant effect on the noise pollution produced. The noise level around the Nurul Hidayah Mosque, Jalan Salabenda Raya, Bogor Regency which has been measured the smallest is 56.4 dBA. This value exceeds the noise threshold of the Noise Level Standard Value for the Ministerial Decree, which is 55 dBA. So that it requires attention and cooperation from the government and the community to overcome the noise in the worship area. The calculation and analysis obtained is on the equation with the largest R Square value on the fourth day of the study, the third point (Sound Level Meter 3), with a contribution of 22.67%. Like the equation on the side, y = 73.251 + 0.004x1-0.311x2-0.003x3. The meaning of this equation is that if there is no decrease in the speed of motorbikes, private cars and public transport cars, the noise pollution level in SLM3 is 73,251 dBA. If there is an increase in the speed of public transport cars by 0.004, the decrease of motorbikes by 0.311, and an increase in the speed of private cars by 0.003, the noise pollution level will decrease by 0.31 dBA at SLM3.

Abstract. The method of determining the accumulation of condensate by registering the noise level in the respiratory circuit of ventilators is substantiated. According to the proposed method, the condition and performance of the apparatus is monitored during artificial lung ventilation and oxygen therapy. With hardware ventilation, an increasing turbulent flow of a water or gas stream is formed in the respiratory circuit, accompanied by an increase in the noise effect and vibration. An increase in the level of acoustic noise from fluctuations in the accumulation of condensate in gaseous media was recorded by an instrument for objective measurement of sound level a sound level meter. Indicators of noise effects reached a higher level on the wet circuit (the presence of condensation droplets or accumulations of mucus) of the liquid compared with the indicators obtained on the dry breathing circuit. The difference in recorded noise levels reached 10 dB, and increased from 37,73 to 47,36 dB. Areas of the respiratory circuit with the greatest degree of narrowing of the lumen and critical accumulations of water condensate and mucus are a source of turbulence in the air flow and increased noise. In conditions of prolonged artificial ventilation of the lungs, the rate of humidified air-gas flow is constantly changing, especially with hardware modeling of the phases of inspiration and expiration, and an increase in temperature in the humidifier chamber. The proposed technique is designed to identify critical levels of water condensate in the apparatus breathing circuits by recording the intensity of the increase in noise level and choosing the rational mode of operation of medical equipment. Data on the emerging critical situation are displayed on the sound level meter screen and inform medical personnel about the need to rehabilitate the circuit of the artificial lung ventilation apparatus. The primary field of application is resuscitation and intensive care units, medical transport teams during in-hospital or inter-hospital transportation, and surgical operating rooms during inhalation anesthesia.

Noise can occur anywhere, including at educational institutions. Noise research at educational institutions began to be studied a lot because of the negative impact on the teaching and learning process and disrupt the performance of teachers and students. Some studies show that schools or universities located on the edge of the road, show noise levels that exceed quality standards. This research was conducted at educational institutions located along the east Frontage Road Jl A.Yani Road, Surabaya, by measuring noise levels at 3 locations, in daylighting measurements with 4 measurement times (L1-L4). Data collection and processing was carried out by referring to the quality standard of KEPMENLH No. 48 of 1996. Data was measured using a sound level meter for 10 minutes for each measurement, with a reading every 5 seconds to obtain 120 data. Data processing results are compared with the standard noise level. The noise value at SD Margorejo I / 403 is 82.2 dB, UIN Sunan Ampel Surabaya is 79.76 dB, and SMK 3 Surabaya is 80.06 dB. The noise level value has exceeded the established quality standard, which has maximum of 55 dB for the educational intitutions area. The source of noise comes from the activities of motorized vehicles in and around educational institution that is quite crowded. Another cause of the high noise value is the train activities along the east frontage road Jl A.yani Surabaya, as well as the distance of the noise source with research location that relatively close.
