Abstract

This study aims to develop and evaluate an adaptive lighting system to enhance the efficiency of microalgae cultivation in closed environments. The system integrates a photovoltaic solar panel, energy storage, and an IoT-based controller that dynamically regulates LED illumination according to real-time environmental parameters. Nannochloropsis sp. was cultivated using seawater medium enriched with nutrients, with two groups established: a control system with static LED lighting and a treatment system with adaptive LED control. Environmental conditions, including water temperature and pH, were monitored using calibrated DS18B20 and pH-4502C sensors, validated against standard instruments (error ±0.1). Biomass productivity was measured weekly through gravimetric methods.

Experimental results show that the adaptive lighting group achieved an average biomass concentration of 3.1 mg/L, compared to 2.9 mg/L under static lighting, corresponding to a 7% increase in synthesis efficiency. In addition, the adaptive system reduced unnecessary energy consumption by synchronizing LED output with ambient light and photosynthetic demand. These results align with previous studies on the role of red–blue spectra in enhancing photosynthesis efficiency, while extending the concept by introducing automated adaptive control powered by renewable energy.

The findings demonstrate that engineering the light environment through adaptive, IoT-based control contributes to higher biomass yield and energy efficiency, supporting the scalability of sustainable bio-resource production and its potential applications in green technology and eco-friendly tourism.
