Abstract

Selada (Lactuca sativa L.) merupakan tanaman hortikultura yang banyak dibudidayakan menggunakan sistem aeroponik, namun pertumbuhannya sangat dipengaruhi oleh kestabilan kelembaban pada zona akar. Penggunaan sistem penyemprotan berbasis timer belum mampu menyesuaikan perubahan kondisi lingkungan sehingga kelembaban menjadi kurang stabil, penggunaan nutrisi kurang efisien, dan pertumbuhan tanaman belum optimal. Penelitian ini bertujuan merancang sistem pengendalian mist fertilizer berbasis sensor SHT20 menggunakan metode kendali on-off pada sistem aeroponik vertikal. Sistem dikembangkan menggunakan mikrokontroler ESP32 yang mengendalikan mist maker dan kipas berdasarkan pembacaan kelembaban secara real-time. Pengujian dilakukan selama tujuh hari dengan membandingkan metode kontrol adaptif, penyemprotan kontinu 24 jam, dan timer. Hasil penelitian menunjukkan bahwa metode kontrol adaptif mampu mempertahankan kelembaban rata-rata sebesar 87,65%, menghasilkan pertumbuhan tanaman terbaik dengan rata-rata panjang 9,46 cm dan rata-rata lebar 4,26 cm pada hari ke-7, serta mengonsumsi larutan nutrisi sebesar 9,92 L selama periode pengujian, atau sekitar 55,5% lebih efisien dibandingkan metode penyemprotan kontinu 24 jam yang mengonsumsi 22,29 L dengan tetap mempertahankan performa pertumbuhan yang lebih baik.

Lettuce (Lactuca sativa L.) is one of the most widely cultivated horticultural crops using aeroponic systems; however, its growth is highly dependent on maintaining stable humidity in the root zone. Conventional timer-based misting systems are unable to adapt to changing environmental conditions, resulting in unstable humidity, inefficient nutrient utilization, and suboptimal plant growth. This study aimed to develop a DHT22 sensor-based mist fertilizer control system using an on-off control method for a vertical aeroponic system. The proposed system employed an ESP32 microcontroller to regulate the operation of the mist maker and cooling fan based on real-time humidity measurements. System performance was evaluated over a seven-day cultivation period by comparing three operating methods: adaptive sensor-based control, continuous 24-hour misting, and timer-based control. The results showed that the adaptive control system maintained an average relative humidity of 87.65%, achieved the highest plant growth with a plant height of 9.46 cm and a plant width of 4.26 cm on the seventh day after planting, and reduced nutrient solution consumption to 9.92 L, representing approximately 55.5% lower consumption than the continuous misting method while maintaining superior plant growth performance.
