Abstract
Ampas Tebu memiliki kadar air sekitar 50% sehingga dapat menurunkan efisiensi pembakaran apabila dimanfaatkan sebagai bahan bakar biomassa. Oleh karena itu, diperlukan proses pengeringan untuk mengurangi kadar air sebelum digunakan. Penelitian ini bertujuan merancang dan membangun sistem monitoring temperatur inlet dan outlet dengan variasi putaran motor pada proses pengeringan ampas tebu tipe rotary. Sistem monitoring ini menggunakan dua sensor thermocouple tipe-K untuk mengukur temperatur inlet dan outlet. Serta sensor proximity hall effect untuk mengukur kecepatan putaran motor (RPM). Data hasil pembacaan sensor diproses menggunakan ESP32-S3 dan ditampilkan secara real-time pada LCD TFT. Hasil pengujian menunjukkan bahwa system monitoring dapat menampilkan data temperatur inlet, temperatur outlet, dan kecepatan putaran motor selama proses pengeringan berlangsung. Sensor thermocouple tipe-K memiliki tingkat akurasi sebesar 97,4% untuk sensor inlet dan 98,65% untuk sensor outlet, sedangkan sensor proximity hall effect memiliki akurasi sebesar 99,33%. Analisis kalor penguapan menunjukkan bahwa nilai tertinggi diperoleh pada temperatur 130°C dengan kecepatan putaran motor 10 RPM sebesar 1741,64 kJ, sedangkan nilai terendah diperoleh pada temperatur 120°C dengan kecepatan putaran motor 5 RPM sebesar 752,25 kJ. Hasil tersebut menunjukkan bahwa variasi temperatur pemanasan dan kecepatan putaran motor memengaruhi besarnya energi yang dibutuhkan untuk menguapkan air selama proses pengeringan ampas tebu.

Sugarcane bagasse contains approximately 50% moisture, which can reduce combustion efficiency when utilized as a biomass fuel. Therefore, a drying process is required to reduce its moisture content before utilization. This study aims to design and develop a inlet and outlet temperature monitoring system with motor speed variations for the drying process of a sugarcane bagasse using a rotary dryer. The monitoring system employs two type-K thermocouple sensors to measure the inlet and outlet temperatures and a proximity hall effect sensor to measure the motor rotational speed (RPM). The sensor data are processed using an ESP32-S3 microcontroller and displayed in real time on a TFT LCD. The experimental results demonstrate that the monitoring system is capable of displaying inlet temperature, outlet temperature, and motor rotational speed throughout the drying process. The type-K thermocouple sensors achieved an accuracy of 97,4% for inlet sensor and 98,65% for outlet sensor, while the proximity hall effect sensor achieved an accuracy of 99,33%. The analysis of the evaporation heat revealed that the highest value was obtained at a heating temperature of 130°C and a motor speed of 10 RPM, reaching 1,741.64 kJ, whereas the lowest value was obtained at 120°C and 5 RPM, with a value of 752.25 kJ. These results indicate that variations in heating temperature and motor rotational speed significantly affect the energy required to evaporate the moisture contained in sugarcane bagasse during the drying process.
