Green Monitoring System For Energy Saving In Accommodation Services

Bali is an area that emphasizes the economy on the tourism industry. Based on the observation of accommodation services In Bali, Indonesia shows that several hotels or villas are installed with energy-intensive devices. This study aims to produce an energy monitoring system consist of an automatic electrical control system and an energy monitoring information system. The system is to help controlling and monitoring energy use in accommodation services, named the Green Monitoring System. The automatic control system uses a Programmable Logic Controller which consists of a DHT11 sensor, ACS712 electric current sensor, and infrared. Electronic devices that are controlled by this system are Air Conditioning (AC). Data obtained from the electrical control system, is then processed and displayed through a monitoring information system. The concept of monitoring information system development was developed with a green software development life cycle approach. This study produced two information system prototypes and the results of the analysis show that differences in design and coding have a significant impact on the greenness of information systems.
