Electronics Nuclear engineering description: Conventional electrical appliances that still use manual controls are prone to wasting energy if they forget to turn off the device when they are out of the house. While IoT makes it easier to control devices, the downside is the inability to monitor real-time conditions, such as ensuring lights are actually receiving voltage and functioning. In addition, the issue of home security and safety has become very important, especially with the increase in crime and fire cases due to LPG gas leaks. This research aims to design an IoT-based Smart Home Automation and Security System prototype using NodeMCU ESP8266 to improve home efficiency, security, and safety. The system incorporates automation features to control lights, fans, and garage doors through the Blynk app, complemented by real-time monitoring with light and voltage sensors on the lights. In addition, the security features utilize MQ-2 gas sensors to detect gas leaks and magnetic switches to monitor door openings, with notifications to mobile devices. This research produces an automation system for electrical equipment such as lights, fans, garages and can monitor the real time condition of lights by detecting light and voltage on the lights. Produce a security system to monitor gas leaks and monitor the open and closed activities of the house door. The performance of the tool works well. In the gas sensor, the maximum distance that can be detected is 1-15cm. Real-time monitoring of lamp voltage produces an error percentage of 0.53%. Based on the tests that have been carried out that both from software and hardware, all functional systems can run well. date: 2025 type: Thesis type: NonPeerReviewed format: text language: id identifier: https://eprints.untirta.ac.id/46068/1/FREDY%20KUSUMA%20NUGRAHA_2283200032_FULL%20TEXT.pdf format: text language: id identifier: https://eprints.untirta.ac.id/46068/2/FREDY%20KUSUMA%20NUGRAHA_2283200032_CP.pdf format: text language: id identifier: https://eprints.untirta.ac.id/46068/3/FREDY%20KUSUMA%20NUGRAHA_2283200032_01.pdf format: text language: id identifier: https://eprints.untirta.ac.id/46068/4/FREDY%20KUSUMA%20NUGRAHA_2283200032_02.pdf format: text language: id identifier: https://eprints.untirta.ac.id/46068/5/FREDY%20KUSUMA%20NUGRAHA_2283200032_03.pdf format: text language: id identifier: https://eprints.untirta.ac.id/46068/6/FREDY%20KUSUMA%20NUGRAHA_2283200032_04.pdf format: text language: id identifier: https://eprints.untirta.ac.id/46068/7/FREDY%20KUSUMA%20NUGRAHA_2283200032_05.pdf format: text language: id identifier: https://eprints.untirta.ac.id/46068/8/FREDY%20KUSUMA%20NUGRAHA_2283200032_REF.pdf format: text language: id identifier: https://eprints.untirta.ac.id/46068/9/FREDY%20KUSUMA%20NUGRAHA_2283200032_LAMP.pdf identifier: KUSUMA NUGRAHA, FREDY (2025) RANCANG BANGUN PROTOTYPE SMART HOME AUTOMATION AND SECURITY SYSTEM BERBASIS INTERNET OF THINGS (IoT) MENGGUNAKAN MIKROKONTROLER ESP8266.
