Abstract

Hydroponics is a method of growing plants that does not use soil as a medium, but rather water as a growing medium. The water used as a growing medium needs to have its nutrient quality and acidity levels maintained, so hydroponic farmers must constantly monitor the water quality at all times. Manual water quality monitoring will cause fatigue, and if water nutrients are not well maintained, it can also lead to poor results. In this study, a water control method for hydroponics was designed to maintain good water quality in terms of nutrient levels, water height, and water acidity in the container. This water control operates simultaneously and continuously according to the water quality conditions in the container. Designed using ESP32 as the data processing and control device to generate faster responses. So, hydroponic farmers no longer need to constantly monitor and control the water's nutrient levels in their containers. Additionally, this study also designed an internet of things (IoT)-based monitoring system so that water quality control can be monitored from anywhere and at any time. This research has been tested with good measurement levels for each sensor. The pH sensor has an accuracy level of 99.78% calculated by MAE, the TDS sensor has a reading accuracy level of 96.9%, and the water level sensor reads water height with 100% accuracy. Testing was conducted several times on water samples with varying levels of nutrients and acidity. Key words: ESP32, internet of things (IoT), nutrisi hidroponik, pH air, sistem kontrol dan monitoring hidroponik Hidroponik merupakan cara menanam tumbuhan yang tidak menggunakan media tanah melainkan media tanam berupa air. Air sebagai media tanam perlu untuk dijaga kualitas nutrisi maupun tingkat keasamannya sehingga para petani hidroponik harus selalu memantau kualitas air setiap saat. Pemantauan kualitas air secara manual akan menyebabkan kelelahan dan apabila nutrisi air tidak terjaga dengan baik bisa berdampak pada hasil yang tidak baik pula. Pada penelitian ini dirancang suatu metode kendali air pada hidroponik untuk dapat terjaga kualitas baik tingkat nutrisi air, ketinggian air, maupun tingkat keasaman air dalam wadah. Kendali air ini berjalan secara simultan dan terusmenerus sesuai dengan kondisi kualitas air pada wadah. Dirancang dengan menggunakan ESP32 sebagai piranti pemrosesan data dan kendalinya untuk menghasilkan respon yang lebih cepat. Sehingga petani hidroponik tidak lagi melakukan pengendalian setiap saat untuk menjaga nutrisi air pada wadahnya. Selain itu pada penelitian ini dirancang pula sistem monitoring berbasis internet of things (IoT) sehingga pengendalian kualitas air dapat dipantau darimanapun dan kapanpun. Penelitian ini sudah dilakukan uji dengan tingkat pengukuran yang baik untuk masing-masing sensor. Sensor pH memiliki tingkat akurasi 99.78% yang dihitung secara MAE, sensor TDS memiliki tingkat akurasi pembacaan sebesar 96.9%, dan sensor level air membaca tingkat ketinggian air dengan akurasi 100%. Pengujian dilakukan beberapa kali pada sampel air yang memiliki tingkat nutrisi dan keasaman yang berbeda-beda. Kata kunci: ESP32, internet of things (IoT), nutrisi hidroponik, pH air, sistem kontrol dan monitoring hidroponik
