Abstract

Manual coffee bean sorting is highly prone to subjectivity, inconsistency, and low operational efficiency. This study aims to develop an automated classification and sorting system based on the Artificial Intelligence of Things (AIoT). The method integrates a Vision Transformer (ViT) model, TensorFlow Lite, Firebase, and an ESP32 microcontroller within a Mobile–Cloud–Edge Computing architecture. The ViT model was trained on four coffee roast levels to perform real-time inference on Android devices linked to physical sorting actuators. Experimental results showed that the ViT model achieved a 96.87% classification accuracy, while the automated physical sorting mechanism achieved 95.83% accuracy with an average response time of 462 ms. In conclusion, the integration of Vision Transformer and AIoT provides a fast and reliable post-harvest automation solution tailored for smart agricultural applications.

Abstract

Keberhasilan penetasan telur bergantung pada kestabilan suhu dan kelembapan di dalam inkubator. Metode kontrol konvensional seperti on-off maupun PID dengan parameter tetap dinilai kurang adaptif terhadap perubahan kondisi lingkungan yang dinamis. Penelitian ini merancang sistem inkubator telur berbasis IoT menggunakan ESP32 dengan metode Fuzzy Self-Tuning PID yang secara otomatis menyesuaikan parameter Kp, Ki, dan Kd, dilengkapi Telegram Bot untuk monitoring dan pengendalian jarak jauh secara real-time. Hasil pengujian menunjukkan metode ini unggul pada pengendalian suhu dengan MAE 0,1185°C, RMSE 0,1387°C, overshoot 0,59%, settling time 10,5 menit, dan penurunan MAE sebesar 32,94% dibandingkan PID Konvensional. Pada kelembapan, metode ini menghasilkan settling time tercepat 4,5 menit dengan MAE 0,8035%RH yang masih dalam batas toleransi inkubasi.
