Daftar Isi:
- This research aims to design a control system to keep the water level and soil moisture at a level that is suitable to the plant requirment and determines the optimum water level and soil moisture in each growth phase of paddy field cultivation. The water level control system was formed based on on-off controls system using Arduino Uno ATMega328P microcontroller. When the sensor gives input that the water level is below the set points, then microcontroller will command the irrigation valve to open and the drainage valve to close. The volume and time of irrigation and drainage control are dependent to set point. Set point was controlled based on water regime treatment. Water regime consisted of three treatments, which are wet regime (RB), slightly wet regime (RAB), and dry regime (RK). The research result showed that control system was very effective and efficient in controlling the water regime according to the control algorithms. Besides, the research result showed that the water regimes affected the plant growth, land productivity, and water productivity. Treatment of wet regime (RAB) gave the highest number of tiller (138 tillers), yield 194.7 g/hill (equal to 21 ton/ha with assumption of 30 cm x 30 cm spacing) and water productivity 3.16 kg/m3.
- Penelitian ini bertujuan merancang sistem kontrol untuk menjaga tinggi muka air dan kelembaban tanah pada level yang dibutuhkan tanaman dan mengkaji tinggi muka air dan kelembaban tanah optimum pada setiap fase pertumbuhan budidaya padi. Sistem kontrol tinggi muka air dibentuk berdasarkan sistem kendali on-off dengan menggunakan mikrokontroler Arduino Uno ATMega328P. Ketika sensor memberikan input bahwa tinggi muka air berada di bawah set point maka dengan perintah mikrokontroler valve irigasi akan terbuka dan valve drainase tertutup. Jumlah dan waktu pemberian dan pengeluaran air irigasi tergantung set point. Set point dikontrol berdasarkan perlakuan rejim air. Rejim air terdiri dari 3 perlakuan yaitu Rejim Basah (RB), Rejim Agak Basah (RAB) dan Rejim Kering (RK). Hasil penelitian menunjukkan bahwa sistem irigasi otomatis sangat efektif dan efisien dalam mengendalikan tinggi muka air sesuai dengan algoritma kendali. Selain itu, hasil penelitian menunjukkan bahwa perlakuan rejim air mempengaruhi pertumbuhan tanaman, produktivitas lahan dan produktivitas air. Perlakuan rejim agak basah memberikan jumlah anakan tertinggi (138 anakan), hasil tanaman tertinggi 194,7 g/rumpun (setara 21, 6 ton/ha dengan asumsi jarak tanam 30 cm x 30 cm) dan produktivitas air tertinggi 3,16 kg/m3.
