Abstrak-Efisiensi, efektifitas dan penghematan energi listrik telah menjadi topik penelitian yang menarik banyak peneliti sekarang ini. Model teknologi telah banyak yang diusulkan untuk meningkatkan efektifitas dan hemat energi listrik bagi hajat hidup masyarakat. Salah satu contohnya adalah model teknologi Smart Home. Model Smart Home yang diusulkan pada penelitian ini dikendalikan secara terpusat oleh sebuah mikrokontroler Arduino Uno. Mikrokontroler mendeteksi output dari dua sensor magnetik yang terpasang di pintu masuk. Tanggapan mikrokontroler terhadap dua output sensor magnetik berupa kendali terhadap lampu ruang, kipas angin, perangkat pengusir nyamuk dan tampilan LCD. Sistem akan bekerja otomatis ketika seseorang masuk ke dalam rumah. Lampu ruang akan menyala secara otomatis, kipas angin akan bekerja sesuai dengan kondisi suhu ruang dan perangkat pengusir nyamuk akan bekerja secara otomatis. Hasil pengujian menunjukkan bahwa model Smart Home yang diusulkan dapat bekerja dengan baik sesuai perancangan dengan tingkat keberhasilan sebesar 100%.

Kata Kunci : Smart Home, Kendali Otomatis berbasis Arduino, Arduino, MikrokontrolerAbstract -Efficiency, effectiveness and electrical energy saving have become topics of research that attracts many researchers today. Model of technology has been widely proposed to improve effectiveness and energy saving for the livelihood of the peoples. One of example is a model of a Smart Home technology. Smart Home models proposed in this research is controlled centrally by an Arduino Uno microcontroller. Microcontroller detect output from the two magnetic sensors installed in the entrance. Microcontroller response to the two outputs of magnetic sensors in the form of control of room lighting. fan, mosquito repellent and LCD. The system will work automatically when someone inside the house. Room lights will turn on automatically, the fan will work in accordance with the room temperature conditions and mosquito repellent device will work automatically. The test results show that the proposed model of a Smart Home can work well according design with a success rate of 100%.
Fire due to Liquefied Petroleum Gas (LPG) gas leak is one of the disasters that still often occurs in the community. Community ignorance of safety standards in using LPG gas is one reason. Fires can be prevented if at the time of the LPG gas leak can be detected earlier. Therefore we need a system that can monitor the condition of gas leaks and fires remotely. Internet of things (IoT) technology can be applied to this monitoring system so that information on LPG gas leaks and fires can be monitored remotely. The Internet of Things (IoT) based LPG and Fire leak monitoring system is a concept that utilizes internet connectivity between smartphone devices connected to sensor devices. The devices used to support this system include NodeMCU ESP8266 as a microcontroller and as a liaison to the internet, MQ-6 gas sensors and flame sensors as sensors for detecting gas and fire leaks, buzzers as alarms, and fans as neutralizing gas levels in the room. Data obtained by the sensor will be uploaded to the database via the internet and can be accessed through an android application. The results of the design show that the android application can display notifications when a gas leak or fire occurs. In testing the performance of data transmission, the results show that the highest data transmission delay is 64,61 seconds, and the lowest delay time is 61,56 seconds, the highest throughput value is 747,6 bits/second, and the lowest value is 285,4 bits/second.
