Abstract
Hydroponic farming is increasingly being found in Indonesia. However, the increase of the number of buildings made hydroponic cultivation could have not get enough sunlight because it could be blocked by the shade of the buildings. Therefore, this study was conducted to fulfill light requirement of plants on hydroponic installation by designing an automatic artificial light control system with dimmer module. The method of this study used engineering method with designing activities. The design result of the automatic control system for controlling artificial light consisted of several components, namely, microcontroller, LED 50W, light intensity sensor, and dimmer module. This control system could emit red-blue light up to 3000 lux at 40 cm above the plants to provide 277,77 umol/m2/s of PPFD or equal to 15000 lux of natural sunlight. The mechanism of this control system is that the light intensity sensor would read the intensity of sunlight, then compare it to the amount of light that the plants need, so that the LEDs could provide light according to the lack of light the plants need.
