INTEGRASI TEKNOLOGI KOMUNIKASI DIGITAL DAN PANEL SURYA DALAM REKAYASA PENCAHAYAAN ADAPTIF PADA SINTESIS MIKROALGA
Keywords:
digital communication, solar panel, adaptive lighting, microalgae synthesis, greenAbstract
This research develops an adaptive lighting system for microalgae synthesis by integrating solar panels as a renewable power source and Internet of Things (IoT)-based digital communication technology. The system is designed using an ESP32 microcontroller connected to light (LDR), temperature (DS18B20), and pH (pH-4502C) sensors to regulate LED grow lights in real time. The adaptive control algorithm automatically adjusts light intensity—reducing brightness when natural light is sufficient or water temperature increases, and increasing brightness when natural light is low or pH decreases.
Experimental results show that the adaptive system successfully maintained culture stability, with water temperature controlled at 27–28 °C and average microalgae biomass reaching 2.98 mg/L. In terms of energy performance, the adaptive lighting system consumed only 70–75 Wh/day compared to 120 Wh/day for a static lighting system, resulting in approximately 38% energy savings.
This study demonstrates the potential of combining IoT-based adaptive control with renewable energy to support efficient and sustainable microalgae cultivation. The proposed system can serve as a model for green technology applications in ecological-based industries and green tourism development.
