      "abstract": "Kartini Reactor is a research reactor that requires accurate monitoring of the tank\r\nwater level to prevent the risk of overheating, meltdown, and radiation leakage. The\r\nexisting monitoring system is only active while the reactor is operating and can\r\nonly be accessed from the control room, making it insufficiently flexible for realtime\r\nmonitoring. This research aims to design, build, and test a water level\r\nmeasurement device for the Kartini Reactor tank based on the HC-SR04 sensor and\r\nthe ESP32 microcontroller. The device design was carried out by creating the\r\nhardware and software design using EasyEDA, SketchUp, and Visual Paradigm\r\nsoftware. The device construction was carried out by assembling the hardware and\r\ndeveloping the software using Arduino IDE (version 2.3.4) software. The device\r\ntesting was carried out by collecting water level data on the Kartini Reactor tank\r\nusing the constructed device, then processing the data to obtain the accuracy and\r\nrepeatability precision of the device. The design results include a circuit schematic\r\ndesign, a PCB design, a housing design, and a programming flowchart for the\r\nsoftware embedded in the water level measurement device. The construction results\r\nconsist of a hardware subsystem comprising the sub-subsystems of two HC-SR04\r\nsensors, an ESP32 microcontroller, an MCP4725 module, an ILI9488 TFT display,\r\nand RS485 communication. This subsystem is integrated through a software\r\nsubsystem in the form of program code consisting of several sub-subsystems,\r\nranging from HC-SR04 sensor reading, data processing using the moving average\r\nmethod followed by conversion into voltage, data display via RS485\r\ncommunication and the ILI9488 TFT LCD, to data transmission to the IoT Google\r\nDrive platform via a Wi-Fi connection. The test results show that the device\r\nachieves an accuracy of 98.29% and a repeatability precision of 99.87%. Based on\r\nthese results, the water level measurement device for the Kartini Reactor tank\r\nbased on the HC-SR04 sensor and the ESP32 microcontroller has been successfully\r\ndesigned, built, and tested.",
