Abstract

Based on Government policies that continue to encourage increased use of domestic products (P3DN) and enlarge the level of domestic components (TKDN) to realize the independence of the domestic industrial sector, we are trying to make an instrument that will be implemented to determine the level of road damage, with accelerometers, ultrasonic sensors and GPS which become a unit in the instrument that we will make under the name “Ultrasonic Surface Rough meter". To find out the success of the prototype product “Ultrasonic Surface Rough meter” carried out various tests and one of them was the prototype component test “Ultrasonic Surface Rough meter” which consisted of ultrasonic sensor component tests, accelerometer component tests, and Global Positioning System (GPS) tests and here only focused on ultrasonic sensor tests, The results of acceleration measurements using the prototype “Ultrasonic Surface Rough meter” carried out by statistical analysis on all tests using accelerometers on the prototype “Ultrasonic Surface Rough meter” can be said to be “Valid and correct".
