Pengoperasian pintu irigasi secara manual masih menjadi kendala utama di banyak wilayah pertanian Indonesia, terutama ketika akses lapangan sulit dan cuaca ekstrem. Penelitian ini mengembangkan dan mengevaluasi secara kuantitatif Sistem Kendali Otomasi Pintu Irigasi berbasis IoT yang dilengkapi rotary encoder E6B2-CWZ6C, proximity sensor Fotek PM12-04N, PLC Siemens S7-1200, dan Raspberry Pi 4B, dengan sumber energi panel surya 550 Wp dan baterai VRLA 12 V 100 Ah. Pengujian lapangan dilakukan di Bendungan Sukoanyar, Kabupaten Malang, pada enam tingkat bukaan (10–60 cm) dengan lima kali pengulangan. Hasil menunjukkan bahwa sistem IoT mencapai akurasi posisi rata-rata 99,04 % dan reliabilitas operasi 93,3 %, jauh lebih tinggi dibandingkan sistem manual (masing-masing 96,09 % dan 76,7 %). Meskipun waktu respons sistem IoT rata-rata 23,6 % lebih lambat, performa keseluruhan tetap unggul dan layak diterapkan di lapangan. Temuan ini membuktikan bahwa integrasi IoT mampu meningkatkan presisi dan keandalan pengendalian pintu irigasi secara signifikan, sekaligus mendukung ketahanan pangan dan pemanfaatan energi terbarukan di kawasan pertanian terpencil.
Kata Kunci: irigasi otomatis, IoT, rotary encoder, sensor proximity, PLC, panel surya, akurasi posisi, reliabilitas
