PENGARUH TEKANAN ANGIN PADA KONDISI BAN BASAH DAN KERING TERHADAP EFISIENSI PENGEREMAN MENGGUNAKAN BRAKE TESTER

Good braking efficiency is necessary to ensure the vehicle can stop quickly
and safely, especially in emergency situations. There are several factors that can
affect efficiency, such as air pressure and the condition of the tires when wet and
dry. This study aims to determine whether there is any effect of wind pressure above
standard (39 PSi), according to standard (29 PSi), or below standard (19 PSi) when
the tires are wet and dry on braking efficiency using a brake tester. This research
can be used as a standard for UPPKB prior to testing brake efficiency.
This research was conducted using an experimental method with variations
in air pressure (39 PSi, 29 PSi, and 19 PSi) on wet and dry tire conditions and was
carried out with five tests and then the average was taken. The data analysis used in
this research is descriptive quantitative. The results of this study are when the tires
are wet, the air pressure increases from 39 PSi to 16% to 19 PSi. When the tires
were dry, the air pressure increased from 39 PSi to 13.75%. In addition, the
condition of the tires also affects the efficiency of the brakes. Air pressure of 39
PSi, there is a 34.8% decrease from dry tires to wet tires. At a wind pressure of 29
PSi, there is a decrease in efficiency of 33.75%, and at a wind pressure of 19 PSi,
there is a decrease of 32.55%.
