Abstract

Technological developments are carried out to support human needs to be more practical in life, one of which is in the household sector. This is the basis of this research. By using NodeMCU and Arduino Uno as microcontrollers for Smart Home systems with the IoT concept. With the creation of a Smart Home system with the IoT concept, it is hoped that the value of efficiency and security can be achieved at home. In this research, NodeMCU is implemented as a microcontroller in Smart Home system with IOT concept. This system is designed by using Telegram Messenger and keypad as input or notification media on this system. When inputting chat, the chat input data is read by the program for verification. If the verification is not successful then the system does not respond followed by reprogramming the chat input, if the verification is successful then the BOT will respond then send an input signal to the microcontroller for processing, after processing the microcontroller will send an output signal (On/Off) to be sent to the relay which will be forwarded to the output components (Solenoid Door lock, magnetic sensor, Buzzer). By implementing a Smart Home system with the IoT concept, we can take advantage of existing technology. The Smart Home system with the IoT concept is also safe because only people who have certain access can control the house such as unlocking the door and turning on the magnetic sensor remotely. Keywords: NodeMCU ESP8266, Arduino Uno, magnetic sensor, door solenoid, relay, power supply, buzzer, telegram and arduinoIDE

Abstract

Library SMAN 2 North Cikarang not using the means of internet or computer and still use manual methods to manage the catalog of books and other administration. Due to its management is considerable and complicated as well as to address some of the issues that arise over the solutions that can be applied is to Designing Information System Application Library Books At SMAN 2 North Cikarang. To keep books neatly arranged, organized by category respectively, and can increase the accuracy of the low in the recording process of borrowing books can be overcome with the new system. Development of the proposed system is done in two stages, namely, the stage of data collection methodology comprised interviews, field studies, literature studies and the next stage is the development of software with waterfall method, using the Application Programming PHP, and MySQL as the database server. For system design tool using Data Flow Diagrams (DFD), Entity Relation Diagram (ERD), Data Dictionary, as well as hardware and software specifications. With the Book Lending Library Information System, is expected to assist officers in serving the transaction Library borrowing and returning library books. And makes it easy for members of the Library make the process of borrowing and returning books at the Library of SMAN 2 North Cikarang. Keywords: Information Systems, Web, Library, Waterfall, PHP, MySQL

Abstract

The widely proposed technological model of increasing savings in electrical energy at overuse is an interesting topic for many studies because of the effects of excess electricity usage itself. And the technology model applied is a smart home for this problem, using a microcontroller for automatic devices using a motion sensor, namely a PIR (passive infrared) sensor for controlling lights in a room. With this method can reduce and save the cost of using lamps in vain from forgetting to turn off the lights. And the device will turn on the light when it detects movement and will turn off the light when it doesn't detect any movement. by using the Kwh cost calculation algorithm, we will find out the costs to be paid from the number of times the lights are on. The test results show that this device can work well according to the design with a success rate of 100%.. Keywords: NodeMCU, Smart Home, Remote Relay, Sensor PIR
