IoT Based Space Lighting Decision Support System Using MQTT and Fuzzy Tsukamoto Protocols

Abstract

Abstract

The use of lamp is really needed in adding lighting to a room, because natural light cannot cover the entire room. Especially the room that has a large size and has less light ventilation. So that the lighting in the room can be considered according to lighting standard or not. Therefore, a decision supporting system is really needed for room lighting based on the internet of things and uses MQTT protocol Fuzzy Tsukamoto logic method.

MQTT protocol used is CLOUDMQTT as place to save data or called broker. CLOUDMQTT has four important instances info which are server, user, password and port. Those four instances info are used to connect application program with the broker. So, the system can do subscribe and publish from broker to the application. For Fuzzy Tsukamoto the combination of rule is built from three membership functions those are light intensity, time and lamp condition. The combination of rule from two variables which are light intensity and time produces 20 combination of rule. Deffuzification of Fuzzy Tsukamoto is obtained by taking center average grades.

Based on the test result which has been conducted at the Uniti PSTI Intelligent System Laboratory of Mataram University the result obtained with the highest intensity value 93 lux and the lowest intensity is 42 lux, with result decision is to always turn on the lamp. So the lighting in the room has not been qualified to lighting standard based on SNI lighting. With a standard of 250 lux.
