Abstract :
Portable is derived from the word portable, which means that according to the Big
Indonesian Dictionary (KBBI), the tool is easy under, easy to move, easy to carry.
This portable disability guidance system for parking automatically uses an
ultrasonic sensor DT-SENSE ULTRSONIC RANGER (USR) which is used to
measure the distance between the portable and the parking lot based on the
Arduino UNO microcontroller. Portable disability car guide system for parking
automatically is a device used to help park vehicles in parallel for people with
disabilities. Limitation of vision towards the back and minimal lighting at night.
The purpose of this research besides helping to park the car automatically and
safely, is also knowing the accuracy of the distance between the portable and the
actual distance mapping, where the measured distance starts at the starting
distance of 250 cm. The LED is green then when portable on a distance of 150
cm. LEDs are yellow and 30 cm. Red and portable LEDs stop. Testing distance
measurements using 2 different ultrasonic sensors namely the DT-USR ultrsonic
sensor and the HC-SR04 ultrsonic sensor with the aim of finding out the
measurement results of 2 different sensors. The results of the measurement of
portable testing using the fuzzy program the value of the percentage of errors is
0% and the value of the percentage of errors not using the fuzzy program is
0.91%.
