Utilization of Arduino UNO Technology and Arduino IDE to Create Electrical Disconnect Products for Electronic Equipment

Today many people often forget to turn off household appliances such as fans or lights, which results in the flow of electricity from the socket even when not in use, resulting in excessive power consumption. Electricity tariff for the first quarter of 2019: IDR 1,115 / kWh for medium voltage customers. If the lecture room has 4 lamps where each lamp has 23 watts of power, 2 Daikin AC units with 1 PK each, each air conditioner has 840 watts of power. Acer S1213Hn LCD projector has the power: 250 Watt, the total cost of electricity consumption per hour and usage for a month of 26 days for the lecture hall consisting of lamps, air conditioner and LCD projectors is IDR 58,617.78. The research method used is literature study and data collection, technology concept design, development preparation, hardware assembly, Arduino UNO coding, upload coding to hardware, technology testing. To find out the test results whether the technology can work properly, it must be applied directly by connecting the technology that has been created with electricity directly. The way that can be done is to connect the Arduino with mains power using a DC 5 V adapter then connect the relay to a 220 V AC power source and a 220 V halogen lamp. After everything is connected, the lights can be turned on by bringing the registered RFID closer to the RFID Reader, if you want. set how long it takes for the light to turn on can press a button on the IR remote


INTRODUCTION
The Ministry of Energy and Mineral Resources (ESDM) noted that the realization of national electricity consumption increased throughout 2018 to 1,064 kWh per capita. This condition is considered to show a positive trend towards equality in consumption in developed countries. "National electricity consumption has increased now to 1,064 kwh per capita. Yes, that's not bad," said ESDM Minister Ignasius Jonan, at the Ministry of Energy and Mineral Resources, Jakarta, Thursday (24/1/2019).
Because of their busy life, nowadays many people often forget to turn off household appliances such as fans or lights, which results in the flow of electricity from the socket even when not in use, resulting in excessive power consumption. (Hang Poh, Ye Tan, Syafiqah Mat-Ruslan, & Othman, 2019) 1 HP Laserjet printer with 550 watts of power, 1 hour operation, cos Φ = 0,85 kWh = P x n x t x cos F (0,85) 1000 (550 x 1 x 1 x 0,85 ) / 1000 = 0,47 kWh/day. (Ida, Rukmi, Kartiwi, & I Nyoman, 2012) Electricity tariff for the first quarter of 2019: IDR 1,115 / kWh for medium voltage customers, namely B-3 Large Businesses with power above 200 kVA and P2 Government Offices with power above 200 kVA.
For example, a PLN customer with a tariff / power of R1T / 1300 VA (Prepaid). Using an electric iron with 350 watts of power, used a day for 3 hours, then the count of usage in 1 month: Daily electricity consumption: 350 watts x 3 hours = 1050 watt hours = 1,050 kWh. Monthly usage = 1,050 kwh x 30 days = 31.5 kWh. Tariff: Electricity consumption = total kwh usage multiplied by price per kWh = 31.5 kWh x IDR 1,355.29 = IDR 42,691.64 (rounded off: forty-two thousand six hundred and ninety-two rupiahs).
If the lecture hall has 4 lamps where each lamp has 23 watts of power, the electricity cost per hour and usage for 26 days is Rp. 2,667.08. air conditioner Daikin 2 units with 1 PK each, each air conditioner has a power of 840 watts then multiplied by 2 to 1,680 watts, then the cost of electricity per hour and usage for 26 days is Rp. 48,702,2. Acer S1213Hn LCD projector has a power of: 250 Watts, then the electricity cost per hour and 26 days of usage for a month is Rp. 7,247.5. So the total cost of electricity consumption per hour and usage for a month of 26 days for the lecture hall consisting of lamps, air conditioner and LCD projectors is IDR 58,617.78.
From the above calculations it can be concluded that for the cost of hourly electricity consumption and usage for a month a total of 26 working days for one room, if after finishing lectures then the room is no longer used and forgets to turn off the electronic equipment in it, the more it will increase the burden of the monthly bill. electricity. If something similar happens in several rooms, it will further increase the burden on the electricity bill.
With Arduino UNO and Arduino IDE technology, it is hoped that it can be used as a controller for the use of electricity in the lecture room in the form of a time timer, if the time timer has run out, the electronic device that is used will turn itself off. The formulation of the problem includes how to design the concept of making electric circuit breakers in electronic equipment? How to make electric circuit breakers in electronic equipment? How to apply power cutoff products to electronic equipment?

Literature study and data collection
Looking Assembly in this stage is the assembly of equipment used in producing electric breaker products for electronic equipment

Arduino UNO coding
The stages of writing program code where the program code will be uploaded to the Arduino

. Upload Coding to Hardware
The process of uploading the program code created from the Arduino IDE application to the Arduino UNO device to find out whether the coding made is in accordance with the purpose of creating a power breaker product on electronic equipment

Figure 3. Arduino IDE display
Steps to upload coding to hardware a. Open the Arduino IDE application on your computer. b. Type the script that will be used c. Arduino Uno connection to a computer using USB type B (USB Printer) d. In the Arduino IDE application, select the tab "Tools" point to "Board" and make sure "Board" is selected "Arduino Genuino / Uno". e. Navigate to the "Tools" menu point to "Port", select "Port" which is already registered f. Upload the code from the Arduino IDE to the Arduino Uno by selecting the "Sketch" menu then "Upload". g. Wait until the indicator light on the Arduino Uno flashes.

Result
The test is carried out by connecting directly between the device that has been uploaded the program code to the Arduino UNO and the supporting device with electronic equipment Technology trial flow a. Test the product with a 220 V lamp medium. b. Connect the Arduino to a power source using a DC 5 V adapter. c. Connect the relay to a 220 V AC power supply and a 220 V halogen lamp. d. Conduct a test by pasting registered and unregistered RFID cards. e. Perform a timer test, whether the lights will turn off according to the predetermined timer The results of the trials that have been carried out are as follows

Discussion
To find out the test results whether the technology can work properly, it must be applied directly by connecting the technology that has been created with electricity directly. The way that can be done is to connect the Arduino with mains power using a DC 5 V adapter then connect the relay to a 220 V AC power source and a 220 V halogen lamp. After everything is connected, the lights can be turned on by bringing the registered RFID closer to the RFID Reader, if you want set how long it takes for the light to turn on can press a button on the IR remote.

CONCLUSIONS AND SUGGESTION
This technology is an electric control device where when using existing electronic equipment, the person must have a previously registered RFID card. If you want to set the time for using electrical equipment, you can press the button on the IR Remote. For further development it can be developed using the IoT concept, where electronic equipment can be controlled using a smartphone.  ICCSN 2017, 2017-January, 1491-1495
