Abstract

The accident investigation report of the KNKT (Komisi Nasional Keselamatan Transportasi) stated that one of the factors causing accidents on public transportation was that the brake fluid at the reservation was exhausted, The volume of brake fluid is below the minimum indicator limit or lower level which will potentially be the cause of accident fatality due to reduced thrust of brake fluid on the brake shoes. The author designed a prototype based on arduino uno that will provide real-time data and warn the condition of the brake fluid volume, so that the driver always pays attention to the condition of the braking system. This prototype is simulated on a hydraulic brake system and an Air Over Hydraulic (AOH) brake system that is often used in public transportation. The prototype concept uses the HMI (Human Machine Interface) system and the ANSI 2535.1 standard. The way the brake fluid volume safety warning prototype works is that the ultrasonic sensor HC-SR04 reads the brake fluid capacity of 78% - 68%, the height at the universal reservoir is 7.5cm - 6.5cm, the LCD will display Status: Normal, Oil Voltage: % and the LED lights up green. Brake fluid capacity of 67%- 34%, height on universal reservoir 5.5cm - 3.5cm, LCD will display Status: Medium, Oil Volume: %, LED lights up yellow. If the brake fluid capacity is 33%- 0%, the height at the universal reservoir is 2.5cm - 1.5cm, the LCD displays Status: Danger, Oil Vol:%, the LED lights up red and the buzzer will continue to sound until the brake fluid is refilled and the buzzer does not sound. This type of research is Research and Development with the Planning, Production, Evaluation method. Data analysis uses sensor calibration and Validation from IT, electro, and motor vehicle testing experts. Validation uses Mc Call's Quality Factor standards, Cricket scale, and eligibility criteria. This type of research is Research and Development with the Planning, Production, Evaluation method. Data analysis uses sensor calibration and Validation from IT, electro, and motor vehicle testing experts. Validation uses Mc Call's Quality Factor standards, Cricket scale, and eligibility criteria. The results of the test and calibration show that the data obtained has met the accuracy criteria set by the Indonesian National Standard (SNI) ≥95%. The validation results received a score of 92% with the Very Feasible criteria, which means that it has met the functionality, accuracy and feasibility as well as the purpose of making a prototype safety warning of brake fluid volume.
