The Indonesian agricultural sector faces challenges producing affordably priced food using

sustainable practices. A soilless cultural practice, such as indoor aeroponics, is a compelling alternative to

conventional agriculture. The objective of the present study was to develop a system for micro-climate

management in a pilot-scale indoor aeroponics system. For this purpose, three fuzzy logic controllers were

developed and evaluated to maintain plant chamber parameters (temperature, relative humidity, and light

intensity) at desired set points controlled by embedded system controls designed using BASCOM-AVR

software. The results showed that the fuzzy controllers provided excellent responses and experienced

relatively low errors in all controlled parameters. All parameters changes followed the set point very

smoothly and responded accordingly. The averaged percent of working times in which temperature,

relative humidity, and light intensity were maintained within less than ±1°C, ±5%, and ±30 lux from the set

points were found to be 88.43%, 95.91%, and 85.51%, respectively.
