Abstract

Information system is a system that combines human activities and the use of technology to support management and operational activities. A library is a place that contains a collection of books and other reading materials that are systematically arranged according to the rules so that they can used as a source of information. SMK Tritech Informatics Medan is one of the schools that have library facilities. In library management, it is generally not systemized or computerized, still doing data processing is still manual, by writing in ledgers related to information laying of reading books, writing library memberships, borrowing books and returning books and the difficulty of calculating late repatriation penalties. Another problem is also the difficulty of library employees finding member data and free libraries from each member. Based on this, it is hoped that later the existence of a digital library management information system can help librarians in solving problems and managing libraries well, easily and effectively at SMK Tritech Informatika Medan.

Abstract

The Internet of Things is automation in all fields of activities and aspects of life through technology, electronic connections or digital connections across devices and fields. IoT is the latest technology trend that continues to develop and provides the latest innovations in various sectors, one of which is controlling electrical devices remotely through the internet of things. This system can help make it easier to control without the need to do it manually. With many rooms in a building, it can shorten the time so that you don't have to check the rooms one by one again. The system is implemented using NodeMCU, relay, Apple HomeKit, and Siri (voice) as the system interface. The system takes an average of 0.4 - 3.3 seconds to respond to commands from Apple HomeKit and Siri via a Wifi connection with a distance of 1-10 meters based on monitoring results, and the electrical power control and monitoring system can function properly. The length of the system's response time is not affected by distance, but rather by the network. This system accessed using Wifi is the most effective alternative compared to using longer SMS and Bluetooth with a shorter range. With the implementation of IoT technology, humans can be more effective, efficient, economical, and easy in monitoring and controlling electrical devices at home.
