Abstract

Kualitas Proses pengeringan rajangan daun tembakau merupakan tahapan pascapanen yang sangat menentukan kualitas akhir produk tembakau. Ketidakstabilan kondisi iklim serta keterbatasan metode pengeringan konvensional berbasis sinar matahari menyebabkan kualitas tembakau sulit dikontrol dan tidak konsisten. Oleh karena itu, pada penelitian ini dirancang dan direalisasikan sebuah sistem pengering otomatis berbasis hot air drying yang dilengkapi dengan sistem monitoring temperatur, berat, dan kadar air secara real-time. Sistem monitoring menggunakan sensor RTD PT100 untuk pengukuran temperatur dan sensor load cell untuk pengukuran berat yang kemudian dikonversi menjadi kadar air. Seluruh data diproses menggunakan mikrokontroler Arduino Mega dan ditampilkan melalui Human Machine Interface (HMI) berbasis LCD DWIN. Hasil pengujian menunjukkan bahwa sistem monitoring mampu bekerja dengan baik dan stabil dalam memantau perubahan temperatur, berat, dan kadar air selama proses pengeringan. Sensor RTD PT100 dan load cell menunjukkan tingkat akurasi dan presisi yang baik berdasarkan hasil validasi terhadap alat ukur pembanding. Distribusi temperatur di dalam ruang pengering juga relatif merata berdasarkan hasil simulasi Computational Fluid Dynamics (CFD) dan pengujian aktual. Proses pengeringan berhasil menurunkan kadar air rajangan daun tembakau hingga mencapai kisaran ideal 12–18% secara konsisten, serta sistem mampu menghentikan proses pengeringan secara otomatis saat set point tercapai. Dengan demikian, sistem yang dirancang terbukti mampu meningkatkan efisiensi proses pengeringan dan menjaga kualitas tembakau kering secara lebih terkontrol dan higienis

The quality of the tobacco leaf drying process is a post-harvest stage that greatly determines the final quality of tobacco products. Unstable climatic conditions and the limitations of conventional sun-based drying methods make it difficult to control tobacco quality and result in inconsistency. Therefore, this study designed and implemented an automatic hot air drying system equipped with a real-time monitoring system for temperature, weight, and moisture content. The monitoring system uses a PT100 RTD sensor for temperature measurement and a load cell sensor for weight measurement, which is then converted into moisture content. All data is processed using an Arduino Mega microcontroller and displayed through a DWIN LCD-based Human Machine Interface (HMI). The test results show that the monitoring system is able to work well and stably in monitoring changes in temperature, weight, and moisture content during the drying process. The RTD PT100 and load cell sensors showed good accuracy and precision based on validation results against reference measuring instruments. The temperature distribution inside the drying chamber was also relatively uniform based on Computational Fluid Dynamics (CFD) simulation results and actual testing. The drying process successfully reduced the moisture content of tobacco leaf shreds to a consistent ideal range of 12–18%, and the system was able to automatically stop the drying process when the set point was reached. Thus, the designed system proved to be capable of improving the efficiency of the drying process and maintaining the quality of dried tobacco in a more controlled and hygienic manner
