Analysis of Bedroom Ventilation and Relative Humidity Using CAMS Technology and Air Fan Supply in Sawojajar 2 Area Residential

The air quality index in various big cities in Indonesia is getting worse daily. One of the reasons is the increasing number of factories and vehicles used daily. On the other hand, many families worry about the air's cleanliness. This study aims to monitor and analyze bedroom ventilation and its relative humidity using Complete Air Management System (CAMS) technology. It provides indoor air quality (IAQ), and its technology manages the AC, supply fan, and IAQ remote controllers simultaneously in the house and integrated. A supply air fan has the function of filling a room with clean air, constantly supplying filtered air, and preventing polluted air from outside from entering. This study employs a mixed method of qualitative and quantitative methodologies; the qualitative method is based on observation, while the quantitative way is based on data log. Moreover, a common issue during this research was a lack of air ventilation, which caused the room to be humid and the temperature to be too high, so it did not match the standard room temperature. The idea is to install air conditioners, a supply of air fans, and CAMS to make the area more comfortable when in use.
