Abstract

False alarm in fire detection can cause a huge loss. False alarm is generated by unwanted signal of smoke detector such as outdoor smoke or smoking. Therefore, it is designed a system that can reduce false alarm. The purposed system is built based on three components, those are sensors, actuators and data communication. Sensors are smoke, flame and camera sensor. Smoke sensor is used as the first thing to sense a signal from the system that warns the system there is a fire. Flame sensor and camera are used to confirm that a signal of fire whether false alarm or not. Internet of Things (IoT) is applied to control the system. The result show that the system is applicable.

Abstract

Wind energy can be transformed into electrical energy using wind turbine. Based on rotation axis, there are two types of wind turbine, namely turbine with horizontal axis and the one with vertical axis. Turbine with vertical axis has been known with various names that are Darrieus turbine, Savonius turbine and H turbine. This research designed and implemented a prototype of simple Savonius turbine for small scale wind speed. Resistor with resistance of 200 ohm and LED are used as the load. Material of the prototype is alumunium plate, which is light and easy to find. The experiment was conducted at the beach. Permanent magnet synchronous generator was chosen for generating equipment. Voltage resulted by the generator increased as the wind speed increased. The prototype began rotating at wind speed 2.4 m/s. Average efficiency for Y and D connected load are 4.8% and 14.5% respectively.

Abstract

Micro Hydro (PLTMH) Ngalau Baribuik, Padang - West Sumatra, has operated since 2012. It is currently the only source of electricity for the local community, some of whom work as chicken breeders. Based on community service activities in 2021, information was obtained that the PLTMH's electricity had yet to be utilized optimally. Meanwhile, chicken breeders also needed egg incubators to increase their productivity. This community service activity aims to design an IoT-based automatic egg incubator to optimize the use of renewable energy. Activities started with field visits, making initial plans, designing and testing the machine, handing over the machine, and disseminating knowledge. The designed a smart egg incubator worked well after a 21-day hatching test for chicken eggs. The IoT technology installed on the device also functions appropriately and can show real-time temperature and humidity on mobile devices.
