KARAKTERISTIK PAPARAN CAHAYA LAMPU UTAMA LED 6 SISI DAN PAPARAN SUARA KNALPOT NOB1 NEO SS PADA SEPEDA MOTOR YAMAHA MIO SOUL TAHUN 2010
Abstract
Lights and exhaust are important parts of a motorcycle. Lights are used for
the lighting on motor vehicles and exhaust is used as exhaust channels and sound
absorbers produced from the working engine. The intensity of light exposure which
is under regulatory requirements in the law can reduce the visibility. If the intensity
of light is too bright then it can lead to the risk of accident. The high intensity of
noise exposure produced from the exhaust can cause disturbances in surrounding
environment and the noise can result in health disorder. Therefore, this research is
aimed to find out the level of light intensity of standard headlights and 6-sided LED
headlight as well as to know the level of noise intensity that can be produced from
the standard exhaust and racing exhaust of NOB1 Neo SS on Yamaha Mio Soul 115
motorcycle Year 2010.
The study of the intensity of exposure of motorcycle headlight was conducted
on the Southern crossroad, Bantul and the study of the intensity of the exhaust noise
exposure was conducted at the Sultan Agung Stadium, Bantul. This research also
used luxmeter measuring instrument and sound level meter. The data collected were
obtained from direct measurement on standard headlight and 6-sided LED
headlight with the load weight variation of 40, 50, 60, and 90 with a distance of 0-
100 meters and 2-3 meters to the right. The direct measurement on standard
exhaust and racing exhaust NOB1 Neo SS used the variations without DB killer,
using DB killer, and glasswool weight.
The results of the study show that the intensity of light exposure and standard
headlights tends to be small on 6-sided LED headlights. The farther away leaving
the bright spot on the standard headlight and the LED headlight, the light exposure
is dimmer. The intensity of noise exposure is lower than the NOB1 Neo SS racing
exhaust. The addition to glasswool weight and the use of DB killer variation on
NOB1 Neo SS exhaust can decrease the level of noise.
