Abstract

Metode pengeringan ampas tebu konvensional menggunakan sinar matahari tidak mampu menjamin kualitas hasil pengeringan dikarenakan sangat dipengaruhi oleh kondisi cuaca sehingga menyebabkan jumlah ampas tebu sendiri tidak dapat diprediksi. Oleh sebab itu, diperlukan sistem
pengendalian yang mampu mempertahankan temperatur operasi secara stabil. Pada penelitian ini diterapkan sistem rotary dryer berbasis mikrokontroler ESP32 S3 yang diintegrasikan dengan sensor thermocouple K sebagai elemen sensing untuk temperatur dan aktuator berupa gas valvesebagai elemen kendali aliran bahan bakar untuk suplai panas sistem rotary dryer. Strategi pengendalian temperatur diimplementasikan menggunakan kombinasi kendali proporsional dan metode feedforward untuk meningkatkan kemampuan sistem dalam mereduksi pengaruh gangguan serta mempertahankan kestabilan temperatur di dalam drum pengering. Evaluasi kinerja sistem dilakukan pada beberapa variasi set poin temperatur berdasarkan karakteristik respons sistem dinamik. Hasil pengujian menunjukkan bahwa performa terbaik diperoleh pada set point 130°C. Pada kondisi tersebut, kualitas ampas tebu mengalami peningkatan yang ditunjukkan oleh nilai Gross Calorific Value (GCV) tertinggi sebesar 3.964,08 kCal/kg dengan potensi energi sebesar 3.447,22 Wh. Hasil penelitian ini menunjukkan bahwa sistem kendali yang dikembangkan relatif mampu meningkatkan efektivitas proses pengeringan sekaligus mendukung pemanfaatan ampas tebu sebagai sumber energi bahan bakar.

Conventional methods of drying sugarcane bagasse using sunlight cannot guarantee the quality of the dried product because they are heavily influenced by weather conditions, making the amount of sugarcane bagasse produced unpredictable. Therefore, a control system capable of
maintaining a stable operating temperature is required. In this study, a rotary dryer system based on the ESP32 S3 microcontroller was implemented, integrated with a K-type thermocouple sensor as the temperature sensing element and a gas valve actuator as the control element for regulating the fuel flow to supply heat to the rotary dryer system. The temperature control strategy was implemented using a combination of proportional control and a feedforward method to enhance the system’s ability to reduce the impact of disturbances and maintain temperature stability inside the drying drum. System performance was evaluated at several temperature setpoint variations based on the system’s dynamic response characteristics. Test results showed that the best performance was achieved at a setpoint of 130°C. Under these conditions, the quality of the bagasse improved, as indicated by the highest Gross Calorific Value (GCV) of 3,964.08 kCal/kg, with an energy potential of 3,447.22 Wh. The results of this study show that the control system developed is relatively effective at improving the efficiency of the drying process while also supporting the use of bagasse as a fuel source.
