| Abstrak/Abstract |
Indonesia's agricultural landscape has undergone significant transformation, with
agricultural land decreasing by 668,145 hectares since 2015 due to complex factors including
farmer education, economic conditions, government policies, and population growth. This
decline has exacerbated food security concerns and price volatility. To address these challenges,
precision agriculture, exemplified by plant factories, presents a viable solution. This research
focuses on developing a sophisticated lighting control system to optimize plant growth
conditions within a plant factory environment. By meticulously controlling light intensity,
duration, and spectral composition, we aim to significantly enhance crop yield and quality. Our
system employs an ESP32-Devkit microcontroller and high-power MOSFETs to generate a
sinusoidal irradiance pattern, mimicking natural light conditions. To evaluate system
performance, we integrated a BH1750 light sensor and a DHT22 temperature and humidity
sensor. The light sensor demonstrated high accuracy with RMSE, MAPE, and R-squared values
of 4.34, 1.35%, and 0.999, respectively. Similarly, the DHT22 exhibited reliable performance in
monitoring temperature and humidity. While the developed control system effectively produced
sinusoidal irradiance, further research is imperative to conclusively establish its impact on plant
growth and yield. By conducting comprehensive plant trials, we aim to quantify the benefits of
this innovative lighting strategy and contribute to sustainable agricultural practices. on the SNI. |
