Theft of premium oil in Tank Trucks is very frequent done by irresponsible people. In general, the tank security system uses only the seal on the door of the faucet, therefore the seal can still be duplicated. To overcome this problem, its security system needs to be transferred to an electronic system with premium automatic delivery system control using HC-SR04 ultrasonic sensors and push-button. The system will send the fuel level information (premium) with SMS and display on the LCD when the charging or distribution is complete. There are 3 (three) premium levels that will be applied to the system. The first delivery condition of the tank is a 5 liter tank, the second condition from the tank to the gas station 1 3 liters and the third condition from the tank to the gas station 2 that is 2 liters. This system starts by activating the push button that functions as a motor drive switch and ultrasonic HC-SR04 sensor to detect premium level heights when premium sensitivity reaches heights will turn off the wiper motor driver. Premium volume will be informed to the user (the owner of the tank in the form of SMS using the SIM 900. The advantage of this tool is to detect premium theft in the premium tank by sending SMS ownership from the tank. This system can detect the theft of premium tanks via SMS, apply ultrasonic sensors (HC -SR04) to detect premium level heights the type of mass of the 0.76 kg premix affects the height at the volume of the tank. When the high volume of the 5 liter tank between the sensor and the premium is 7.63 cm, when the 2 liter volume high between the sensor and the premium is 13, 63 cm, while at the time of empty tank (0 liters) the height of sensor with premium is 17,63 cm.
