Abstract

In line with the development of science and technology today, especially in the field of electricity brought many changes in the use of electricity. Electricity is currently needed both industrial and non-industrial. Electricity needs are currently provided by PLN as the main power source. The flow of electricity from the electricity grid is not always continuous in its distribution, one day there must be a blackout that may be caused by interference with the transmission system or distribution system. To anticipate this outage, it is necessary to design an automatic control called an automatic transfer switch and to prepare a backup source, a 2000-watt power inverter. Automatic transfer switch is electrical equipment that functions as a controller of the process of switching the PLN electricity supply to the inverter power supply or vice versa automatically. In the operation of this automatic transfer switch can be operated manually and automatically. Where is in automatic mode, if there is a power outage on PLN this tool is useful for turning on and connecting the power inverter to the load automatically. When PLN revives, this tool will transfer the power source to the load from the power inverter to the PLN electricity. At this time technological advances are developing very rapidly, technology is an inspiration so that life in the world becomes lighter, easier and practical.

Abstract

The vital capacity value of the lungs is very influential with the health of the human lungs because with the results the value of the vital capacity of the human lung can be diagnosed as normal or abnormal of the lungs. This study aims to make a means of detecting respiration gas flow rates in humans using an arduino uno-based YF-S201 flow sensor. From the results of data analysis of respiratory gas flow in adult male breathing with ages (20 years - 30 years), (30 years - 35 years), (35 years - 45 years) and (45 years - 50 years) as many as 15 users. there is an error of 3.86%, the value is generated from comparing the output of the equipment made by researchers with other tools of the brand Spirolab with as many as 15 users of different height and age. From 15 different users there are 2 users with abnormal lung conditions and 13 other users with normal lung conditions. The result of this error occurred because of the 15 users who were less relaxed when exhaling and breathing.

Abstract

The design of this explosive detector is an alternative low-cost explosive detector device that can detect the presence of explosives by comparing the value of the magnetic field so that an object will be known to be an explosive or not. This tool can provide additional assistance in the Juanda airport area which still rarely uses conventional explosive detector equipment because the price is still expensive. This design uses a magnetometer sensor that can calculate the magnitude of the magnetic field in the explosives and will send analog inputs in the form of voltage values to the Arduino displayed with LCD media and sound from the buzzer so that the category of explosives can be detected.

Abstract

TDS meter is a measure of the conductivity of solutes in liquids, this tool is often used as an important component in determining water quality before use. There are still several components to be examined beside TDS, one of which is temperature. Temperature is an important component to measure the feasibility of water. Temperature measuring devices can be used to find out how much the temperature of the liquid being measured. The TDS meter that is already in the general public can only be used to find out the TDS. So, if people want to measure other components such as temperature, a thermometer is needed to measure it, of course this becomes inefficient and requires a higher cost because if you want to measure other components, the public must buy another measuring instrument. Therefore, on this occasion to make measurement tools become more efficient, the writer will design a measuring instrument that can be used to measure 2 components at once, namely a TDS meter and a thermometer designed in one device. TDS meter uses a conductivity sensor and a thermometer uses a DS18B20 waterproof temperature sensor.

Abstract

This research was conducted in an effort to minimize the occurrence of road traffic accidents. In this study detected the level of fatigue and sleepiness from the driver's face video based on the extraction of eye and mouth features using the CNN method. The dataset in this study is 300 data with 3 different classes namely drowsiness 100 data, sleepy 100 data and normal 100 data. The number of epochs used in research to achieve high accuracy is as much as 50. In the test results it is known that the validation of accuracy has increased in each of the input layer results.

Abstract

Water pipe leakage causes financial loss for the user such as PAM or PDAM. YF-S201B flowmeter sensor is a water flow sensor made of plastic with a rotor and hall effect sensor inside. The rotor will spin when the water flow through the sensor. The speed of rotor spin is proportional to the water flow. The hall effect based sensor can be used to detect water flow up to 30 liter/minute (1.800L/hour) thus, the sensor can be used to control the water flow in distribution system and water debit monitoring. The principle of prototype is the placement of sensor before the leakage and after leakage position to obtain different value of water debit. The system will send a short message automatically to the phone if water leakage is detected in the pipeline.
