Hidroponik merupakan cara bercocok tanam tanpa menggunakan tanah sebagai media tanamnya, tetapi menggunakan air yang mengandung nutrisi yang dibutuhkan oleh tanaman. Kelebihan teknik menanam hidroponik antara lain penggunaan lahan yang efisien, penggunaan pupuk dan air lebih efisien dan terkendali. Sedangkan kekurangan dari teknik ini adalah membutuhkan ketelitian, ketelatenan, dan pemantauan secara terus-menerus. Untuk mengatasi masalah tersebut maka dapat memanfaatkan kemajuan teknologi yang sudah berkembang. Saat ini banyak sistem yang mampu mengolah dan mengerjakan pekerjaan manusia yang dilakukan secara manual dapat menjadi lebih mudah, cepat, dan akurat baik dari segi waktu dan tenaga. Salah satunya adalah mikrokontroller Arduino Uno. Terdapat tiga sensor yang digunakan yaitu sensor DHT-22 untuk mendeteksi suhu dan kelembaban, sensor pH untuk mendeteksi nilai pH, sensor TDS untuk mendeteksi nutrisi air pada tanaman. Data-data sensor tersebut dikendalikan oleh Arduino Uno dan datanya dikirim ke server Thingsboard menggunakan protokol MQTT yang datanya ditampilkan dalam bentuk chart dan grafik. Dari hasil pengujian modul sensor yang dilakukan, sensor sudah bekerja dengan baik dengan berdasarkan waktu dengan selisih satu jam.
Birth Control “Keluarga Berencana” (KB) is a government program designed to balance the needs and population.
