Judul: Feeder kelinci ternak otomatis menggunkan prinsip aktuator solenoid
Abstrak: Feeder kelinci ternak otomatis merupakan prototipe yang diciptakan dengan pengaturan distribusi pakan berbentuk pellet pada konveyor sekrup termodifikasi dengan tambahan pintu akses teraktivasi oleh aktuator solenoid. Mikrokontroler Arduino Uno R3 pada prototipe ini digunakan untuk proses perhitungan jarak pintu akses, waktu tempuh pakan, dan kecepatan distribusi pakan. Prototipe ini bermanfaat untuk para pembudidaya/peternak kelinci sebagai inovasi teknologi dalam kegiatan pemeliharaan kelinci secara moderen. Pakan kelinci diatur melalui rotasi motor stepper pada penakar pakan sehingga dapat mengukur porsi pakan secara akurat. Penggunaan motor DC dilengkapi gearbox bertujuan mengendalikan konveyor sekrup agar berputar dengan konstan sehingga menghasilkan gaya dorong pada pakan yang akan didistribusikan. Hasil perhitungan kecepatan distribusi pakan menentukan waktu aktivasi aktuator solenoid yang akan membuka pintu akses pakan untuk keluar dari konveyor sekrup.
