Abstract
Bioetanol merupakan salah satu sumber energi terbarukan yang ramah lingkungan dan memiliki potensi sebagai substitusi bahan bakar fosil. Proses produksi bioetanol umumnya terdiri dari dua tahap utama, yaitu fermentasi dan distilasi. Dalam proses tersebut, kestabilan parameter seperti temperatur, pressure, pH dan level sangat menentukan efisiensi konversi serta kemurnian etanol yang dihasilkan. Penelitian ini bertujuan untuk merancang dan membangun sistem monitoring temperature, pressure, pH dan level pada mini plant produksi bioetanol yang berbahan dasar nira aren. Sistem monitoring difokuskan pada dua tahap utama: pada tahap fermentasi dilakukan pemantauan parameter temperatur, pressure dan pH, sedangkan pada tahap distilasi dilakukan pemantauan temperatur dan level cairan. Pengukuran parameter dilakukan menggunakan sensor RTD PT100, sensor pressure G1/4, pH Industri Analog dan float switch level. Data dari masing-masing sensor dikumpulkan menggunakan dua mikrokontroler Arduino Mega 2560 Pro, kemudian dikirim menuju ESP32 yang akan meneruskan data secara paralel ke database MySQL dan ke tampilan HMI Nextion yang akan menampilkan data secara langsung. Evaluasi sistem dilakukan melalui uji karakteristik statis seperti akurasi, presisi, Error, dan sensitivitas pada masing-masing sensor. Hasil evaluasi digunakan untuk memastikan keandalan sistem dalam memantau proses produksi bioetanol secara real-time.

Bioethanol is a renewable and environmentally friendly energy source with strong potential as a substitute for fossil fuels. The bioethanol production process generally consists of two main stages, namely fermentation and distillation. In this process, the stability of parameters such as temperature, pressure, pH, and level plays a critical role in determining conversion efficiency and the purity of the resulting ethanol. This study aims to design and build a monitoring system for temperature, pressure, pH, and level in a bioethanol mini plant based on aren (palm) sap. The monitoring system focuses on two main stages: during the fermentation stage, temperature, pressure, and pH parameters are monitored, while during the distillation stage, temperature and liquid level are monitored. Parameter measurements are carried out using PT100 RTD sensors, a G1/4 pressure sensor, an Industrial Analog pH sensor, and a float switch level sensor. Data from each sensor is collected using two Arduino Mega 2560 Pro microcontrollers, then transmitted to an ESP32, which forwards the data in parallel to a MySQL database and to a Nextion HMI display for real-time visualization. System evaluation is conducted through static characteristic testing, including accuracy, precision, Error, and sensitivity for each sensor. The evaluation results are used to ensure the system's reliability in monitoring the bioethanol production process in real time.
