RANCANG BANGUN SISTEM HIDROPONIK NFT BERBASIS ARDUINO DENGAN SUMBER TEGANGAN PLTS
No full textHydroponics is a technique of cultivating plants with water that has been added with AB Mix nutrients. The hydroponic system used in this research is NFT. This system uses shallow water and is circulated continuously for 24 hours using a pump so that plants can get sufficient water, nutrients and oxygen. The electricity supply from PLN is not always available and the hydroponic system is not always made in places where PLN electricity is available, therefore in this research the voltage source comes from PLTS. In this research, a 50 Wp polycrystalline solar panel and a 70 Ah battery were used. To produce plants with optimal development, proper nutrition and pH are needed. Therefore, an Arduino-based pH and nutrition monitoring system is used. The results of pH and nutrient readings are displayed on the LCD screen. If the pH and nutrient level readings are outside the predetermined level, the buzzer will sound. To adjust the pH and PPM of hydroponic water to suit the needs of plants, you need to add a pH regulator and AB Mix to the hydroponic water. From the experiment, for every 5 mL of pH down added to 20 L of hydroponic water, the pH will decrease by 0.27, while for every 5 mL of solution A and 5 mL of solution B, there will be an increase in PPM of 50.89.Hidroponik adalah teknik membudidayakan tumbuhan dengan air yang telah ditambahkan nutrisi AB Mix. Sistem hidroponik yang digunakan dalam penelitian ini adalah NFT. Sistem ini menggunakan air yang dangkal dan tersirkulasi terus-menerus selama 24 jam menggunakan pompa sehingga tanaman bisa memperoleh air, nutrisi, dan oksigen yang cukup. Tidak selamanya pasokan listrik dari PLN selalu ada dan tidak selamanya sistem hidroponik dibuat di tempat yang tersedia listrik PLN oleh karena itu pada penelitian ini sumber tegangan berasal dari PLTS. Pada penelitian ini digunakan panel surya polikristal 50 Wp dan baterai 70 Ah. Untuk menghasilkan tanaman yang perkembangannya optimal maka dibutuhkan nutrisi dan pH yang tepat. Oleh karena itu digunakan sistem monitoring pH dan nutrisi berbasis arduino. Hasil pembacaan pH dan nutrisi ditampilkan pada layar LCD. Jika pembacaan level pH dan nutrisi di luar level yang telah ditentukan maka buzzer akan berbunyi. Untuk mengatur pH dan PPM air hidroponik agar sesuai dengan kebutuhan tanaman maka ke dalam air hidroponik perlu ditambahkan pengatur pH dan AB Mix. Dari percobaan, setiap penambahan 5 mL pH down ke dalam 20 L air hidroponik maka pH akan turun 0,27 sedangkan untuk setiap 5 mL larutan A dan 5 mL larutan B maka terjadi kenaikan PPM sebesar 50,89
