Abstract

Kebutuhan energi yang terus meningkat mendorong pemanfaatan sumber energi alternatif yang lebih ramah lingkungan, salah satunya biomassa limbah ampas tebu (bagasse) yang merupakan hasil samping proses penggilingan di pabrik gula. Ampas tebu memiliki potensi sebagai bahan bakar boiler karena memiliki nilai kalor yang tinggi. Namun, kadar air ampas tebu setelah proses penggilingan masih relatif tinggi sehingga dapat menurunkan nilai kalor dan efisiensi pembakaran. Oleh karena itu, diperlukan proses pengeringan yang optimal serta sistem monitoring yang mampu memantau perubahan kadar air selama proses pengeringan secara real-time. Penelitian ini bertujuan untuk merancang dan mengimplementasikan sistem monitoring kadar air ampas tebu pada proses pengeringan menggunakan rotary dryer berbasis sensor load cell. Data hasil pembacaan sensor kemudian dikonversi menjadi nilai kadar air pada mikrokontroler Arduino Mega 2560 dan diteruskan ke mikrokontroler ESP32-S3 untuk ditampilkan pada LCD secara real-time. Pengujian dilakukan menggunakan massa awal ampas tebu sebesar 3 kg dengan variasi temperatur udara panas 110°C, 120°C, dan 130°C serta kecepatan putaran drum 5 rpm, 10 rpm, dan 15 rpm selama 30 menit untuk mengevaluasi pengaruh variasi temperatur dan kecepatan putaran drum terhadap penurunan kadar air ampas tebu serta menentukan kombinasi parameter pengeringan yang optimal. Hasil pengujian menunjukkan bahwa sistem monitoring yang dikembangkan mampu memantau perubahan berat dan nilai kadar air ampas tebu selama proses pengeringan secara real-time. Berdasarkan rata-rata tiga kali pengujian, variasi temperatur 130°C dan kecepatan putaran drum 10 rpm memberikan hasil pengeringan paling optimal dengan menurunkan kadar air ampas tebu dari 50% menjadi 35,5% serta menghasilkan laju pengeringan sebesar 22,73 g/menit. Hasil penelitian juga menunjukkan bahwa peningkatan temperatur udara panas dan variasi kecepatan putaran drum berpengaruh terhadap penurunan kadar air ampas tebu. ==============================================================================================================================
The rising energy demand drives the utilization of more environmentally friendly alternative energy sources, including sugarcane bagasse biomass, a by-product of the milling process in sugar factories. Bagasse possesses significant potential as a boiler fuel due to its high calorific value. However, the moisture content of bagasse post-milling remains relatively high, which can reduce its heating value and combustion efficiency. Consequently, an optimized drying process and a monitoring system capable of tracking moisture content changes in real-time are essential. This research aims to design and implement a bagasse moisture monitoring system for the rotary drying process based on load cell sensors. The sensor data is converted into moisture content values by an Arduino Mega 2560 microcontroller and transmitted to an ESP32-S3 microcontroller for real-time display on an LCD. Experiments were conducted using an initial bagasse mass of 3 kg with hot air temperature variations of 110°C, 120°C, and 130°C and drum rotation speeds of 5 rpm, 10 rpm, and 15 rpm over a 30-minute duration to evaluate their impact and determine the optimal drying parameters. The results indicate that the developed monitoring system successfully tracks weight and moisture content changes in real-time. Based on an average of three trials, the combination of 130°C and 10 rpm yielded the most optimal results, reducing moisture content from 50% to 35.5% with a drying rate of 22.73 g/min. Furthermore, the findings demonstrate that increasing hot air temperatures and varying drum rotation speeds significantly influence the reduction of moisture content in bagasse.
