Abstract

Proses pengeringan sepatu secara konvensional masih terkendala oleh kondisi cuaca dan perbedaan karakteristik termal material sepatu seperti kulit, kanvas, dan mesh, sehingga membutuhkan durasi pengeringan yang berbeda-beda serta rentan menimbulkan kerusakan material apabila tidak dikendalikan secara tepat. Penelitian ini bertujuan untuk merancang prototipe pengering sepatu pintar yang mampu mengakomodasi kebutuhan pengeringan sesuai karakteristik material sepatu, mengimplementasikan algoritma Model Reference Adaptive Control (MRAC) berbasis ESP32 untuk mengendalikan penurunan kelembaban relatif (RH) secara adaptif mengikuti model referensi, serta merancang sistem pemantauan berbasis Internet of Things (IoT) untuk memantau suhu, kelembaban, dan status pengeringan secara real-time. Metode penelitian yang digunakan adalah Research and Development (R&D) dengan model pengembangan 4D, yaitu Define, Design, Develop, dan Disseminate. Sistem kendali adaptif MRAC dengan aturan MIT diterapkan untuk mengatur kecepatan kipas melalui sinyal PWM berdasarkan selisih kelembaban relatif (ΔRH) antara ruang pengering dan bagian dalam sepatu terhadap model referensi, sementara elemen pemanas PTC dioperasikan pada suhu konstan sebagai sumber energi pengeringan. Data suhu, kelembaban, dan duty cycle kipas dikirimkan secara real-time melalui ESP32 ke Google Spreadsheet menggunakan Google Apps Script. Hasil pengujian menunjukkan bahwa sistem MRAC mampu menyesuaikan nilai adaptive gain sesuai karakteristik material, yaitu 1,45 pada kulit, 2,63 pada kanvas, dan 3,00 pada mesh, dengan duty cycle kipas mencapai 100% pada seluruh pengujian dan suhu chamber tetap stabil pada kisaran 28°C. Dapat disimpulkan bahwa prototipe pengering sepatu pintar berbasis MRAC dan ESP32 mampu mengendalikan penurunan kelembaban secara adaptif terhadap perbedaan karakteristik material sepatu tanpa memerlukan penyetelan parameter kendali secara manual untuk setiap jenis material. ***** Conventional shoe drying is still constrained by weather conditions and by differences in the thermal characteristics of shoe materials such as synthetic leather, canvas, and mesh, each requiring a different drying duration and prone to damage when not properly controlled. This study aims to design a smart shoe dryer prototype that accommodates drying needs according to material characteristics, to implement an ESP32-based Model Reference Adaptive Control (MRAC) algorithm to adaptively control the decrease in relative humidity (RH) following a reference model, and to design an Internet of Things (IoT)-based monitoring system for real-time temperature, humidity, and drying status. The method used is Research and Development (R&D) with the 4D model: Define, Design, Develop, and Disseminate. The MRAC controller with the MIT rule regulates fan speed through a PWM signal based on the difference in relative humidity (ΔRH) between the drying chamber and the inside of the shoe relative to a reference model, while the PTC heating element operates at a constant temperature as the drying energy source. Temperature, humidity, and fan duty-cycle data are transmitted in real time through the ESP32 to a Google Spreadsheet using Google Apps Script. Test results show that the MRAC system adjusts its adaptive gain according to material characteristics, reaching 1.45 for synthetic leather, 2.63 for canvas, and 3.00 for mesh, with the fan duty cycle reaching 100% in all tests and the chamber temperature remaining stable at around 28°C. It can be concluded that the MRAC- and ESP32-based smart shoe dryer prototype adaptively controls the decrease in humidity according to differences in shoe material characteristics, without manual adjustment of control parameters for each material type.
