research is to develop a mathematical model capable of converting analog values from the Analog-to-Digital Converter (ADC) into a numerical representation that reflects the actual water turbidity level in Nephelometric Turbidity Units (NTU). The calibration process was performed using a standard Hanna Turbidity Meter with water samples ranging from 0.56 NTU to 500 NTU. Measurement results demonstrated a strong linear relationship between the ADC value (495–686) and NTU, with an average system accuracy level above 90%. Comparison of sensor measurements with the standard instrument showed an error margin below 5%, confirming the reliability of the linear regression model in compensating for optical sensor nonlinearities.

This automatic brake control system is a device that functions as an automatic braking controller on four-wheeled vehicles without the driver having to press the brake pedal or brake manually. This system uses ultrasonic sensors to detect the distance of the car to objects that are in the way both in front and behind the car. Controlled by Arduino Uno microcontroller which is connected to servo motor and buzzer. The system can control the speed of vehicles and parking cars in the parking lot by designing and making a braking and parking system that works using ultrasonic sensors so that it can notify objects or things that are blocking both in front and behind the car. The car can stop quickly and accurately so it doesn't touch the object in front of it and the car can also park properly in the designated parking space.

Therefore, in this study, a design for an automatic water pump on an Arduino Uno-based boat will be made, which functions as a tool to remove puddles in the hull of the boat due to leakage. This tool is able to discharge water on the boat automatically when the water level entering the hull of the boat has exceeded the maximum height limit until the water level is within the tolerance limit which is considered safe and does not interfere with sailing. This tool works automatically using the WLC sensor (water level control) as a tool to monitor the water level, and the Arduino Uno system as a component to run the program by switching the pump. This tool can minimize the occurrence of shipwreck accidents due to boat hull leaks and human error. This system is still applied in the form of a prototype.

soil fertility for plants. This study aims to design a prototype that can be monitored via the Telegram app. The research methodology employs a thinking framework approach. The system is implemented using an Arduino Uno microcontroller and supporting devices, including an ESP8266 Wi-Fi module, an ultrasonic sensor, a soil moisture sensor, a stepper motor and a servo motor. Telegram serves as the monitoring tool, sending notifications connected to the Arduino via a Wi-Fi network. Test results showed that the system operates effectively: the HC-SR04 ultrasonic sensor functions as a water level reader, and the stepper motor opens and closes the water gate. Soil moisture monitoring uses a soil moisture sensor to measure the water content in the soil. If the sensor detects dry soil conditions or a moisture level below 60%, the servo motor will rotate 15° to close the water channel. Conversely, if the sensor detects wet or moist soil conditions, the servo motor will rotate 0° to close the water channel.
