Penelitian ini mengimplementasikan kontrol PID pada mesin pengering cabai untuk mempertahankan stabilitas suhu selama proses pengeringan. Pengaturan suhu optimal dicapai melalui mekanisme tuning PID dengan metode Ziegler–Nichols untuk mengatur parameter Kp, Ki, dan Kd yang dapat menghasilkan respon sistem yang stabil pada suhu setpoint. Mesin pengering terdiri dari sensor DHT22, pemanas, dan mikrokontroler ESP32, serta terintegrasi dengan aplikasi Home Assistant untuk pemantauan dan pengontrolan jarak jauh. Hasil pengujian menunjukkan bahwa pada suhu 60°C menghasilkan keseimbangan optimal antara kecepatan pengeringan dan kestabilan kelembaban. Implementasi kontrol PID berhasil menjaga suhu mendekati setpoint dengan steady-state error sebesar 0,98%, overshoot yang minimal dan settling time yang optimal. Proses pengeringan menghasilkan penurunan kadar air yang signifikan, dengan berat awal 1 kg menjadi 261 gr setelah pengeringan. Tuning PID menunjukkan efektivitas dalam meningkatkan kestabilan suhu dan kualitas akhir produk cabai kering, serta menjadi solusi dalam mengatasi kendala pengeringan cabai secara konvensional.
