Engine scanner unit is a tool used by mechanical power to know the condition of car engine combustion at the time of tune up process done. The level of elements and compounds that dominant in determining categories of combustion of gasoline fuel car engines through the levels of elements and compounds contained in exhaust emissions are Hydrocarbons (HC), Carbon Monoxide (CO), Carbon Dioxide (CO2) and Oxygen (O2). Complete combustion category produces maximum power, fuel efficiency and emission levels according to the threshold. This occurs when there is a balance of the amount of fuel, airflow and ignition in the engine combustion chamber. Elements and compounds contained in car exhaust emissions can be detected with sensors that are sensitive to elemental levels and these compounds are HC, CO, CO2, and O2 sensors. This study aims to display the data pattern category of combustion engine through exhaust emissions based on multi sensor detection processed with signal processing system in the form of Fast Fourier Transform (FFT) process. Furthermore, data pattern is performed in accordance with the category of combustion engine detected. The system is designed with embedded system using Field Programable Gate Array (FPGA) myRIO and LabVIEW programming. The results in the test displays the data pattern and the comparison test of the reference data pattern with the data pattern of the detection result. The comparison test result of data pattern similar to 87% complete engine combustion category and similar to incomplete combustion category 90%.

A multisensory gas device integrated with myRIO module to measure air pollution has been established. This device is programmed using the LabVIEW programming language and can measure CO2, CO, NOX, and HC pollution on roads due to motor vehicle exhaust emissions. The device and the display system are made separately using wireless network communication to make this tool portable. Exhaust Gas Analyzer (EGA) was chosen for device calibration, obtaining 3.62% on the average error after performing 30 tests. The tests for measuring CO, CO2, NOX, and HC gas levels were conducted in several locations in Padang City and performed in the morning, afternoon, and evening. The result showed that the system properly measured CO2, CO, NOX and HC pollution in parks and highways in real-time in parts per million (ppm). It also displayed varied gas measurement results in terms of time and test location with a range of CO gas values at 0.034 – 0.15 ppm, CO2 151.3 – 815.2 ppm, NOX 0.0001 – 0.004 ppm, and HC 0.04 – 0.65 ppm. In addition, the system could perform well in providing warnings by automatically activating the air indicator alert at several measurement places when the gas content on one of the gas elements and compounds at a particular location has exceeded the threshold for the clean air category. Thus, this device can be used as initial research to build a real-time air pollution measurement system using the Internet of Things (IoT).

Real-time system works in a limited period of time in accordance with the deadline time given. The success of a real time system performance is determined by several time components such as release time, processing time and time deadlines. Problems arise when the processing time is not enough due to the delay factor deadline or other factors, while the deadline time has come and the process had to be stopped. When the process is stopped, the results obtained have not been enough to be used as the end result of data systems fail to meet the given time constraint. There are several ways to overcome this, one is to perform preprocessing before the end of the process is done. In the sequential preprocessing system multioperand summation of the operand-operand which can be summed sort operand-operand which has significant influence on the results done first. When the process had to be stopped due to a deadline is coming then the accuracy of the results produced may be used as the final result. This study utilized the method as a preprocessing ascend in sorting systems to sort operand-operand values to be summed from largest to smallest. The results show the accuracy of the rate of change of the summation process in accordance with the needs of real-time system when the process had to be stopped before the end.

Washing hands is an activity that should be routinely carried out by every individual, especially during the COVID-19 pandemic like today. There are many factors that make someone feel lazy and don't want to wash their hands, one of which is not wanting to be bothered by hand washing activities such as taking soap, turning the faucet and others. Experiments have been carried out in the form of testing the response of the sensor to detect the user's hand based on the distance and the reading angle. Furthermore, the ability to set the delay time for rubbing hands is tested to activate the water tap pump for rinsing. Based on the results of trials and analyzes carried out, the sensor response is obtained at a minimum distance of 4 cm and a maximum distance of 140 cm with a view or response area of 1100 horizontal positions and 850 in the vertical position. The water pump and soap pump are active for 3 seconds when the user's hand is detected by the sensor approaching the end of the water tap. The water tap pump comes back on after being delayed for 23 seconds, and the system is able to operate 100% automatically. Thus the minimum time for users to rub their hands for 20 seconds according to health standard protocols can be met.

Carbon dioxide is gas produced by industrial pollution and motor vehicle exhaust emissions. The air is declared clean and healthy for human activities if the CO level does not exceed 15 ppm. Industrial pollution or motor vehicle pollution does not only pollute the outdoor air, but it is very likely to pollute the indoor air. For this reason, a system that is able to monitor and control CO levels in the room has been designed so that it is safe for users while doing this activities. The research stage is carried out by making a series of sensors to detect CO gas and then the sensor circuit is connected to the Arduino UNO microcontroller as an interface with a PC. The program used is LabVIEW programming as a neural programming for displaying Virtual Instruments as display media. The output system is an air purifier system that cleans the indoor air when the CO level is more than 15 ppm. Based on the results of trials and analyzes, the response of the sensor system is able to detect changes in CO gas within 7 seconds. The average monitoring of CO levels result when observed 30 times was 11.47 ppm. The air purifier response time is able to restore indoor CO levels to the maximum threshold of 15 ppm in the fastest time of 3 minutes and 22 seconds.
