Abstract

This study aims to design and develop a temperature and humidity monitoring system for the tempeh fermentation process using the Mamdani fuzzy logic method. The system is designed to monitor fermentation room conditions in real time and control heating devices (lamp) as well as cooling devices (peltier and fan) to maintain temperature and humidity within the optimal range. The hardware consists of an ESP32 microcontroller, DHT22 temperature and humidity sensor, HX711 load cell, 16x2 I2C LCD, and relay modules to control the actuators. The control method applies Mamdani fuzzy logic with three inputs—actual temperature, actual humidity, and temperature setpoint—and three outputs—fan speed, peltier operating intensity, and lamp status. During testing, the fermentation room temperature was recorded in the range of 30–37 °C, while humidity was maintained between 70% to 74%, both suitable for supporting the tempeh fermentation process. indicating normal fermentation activity. Sensor readings were displayed on the LCD and transmitted to the Blynk application for remote monitoring via smartphone. The test results showed that the system was able to maintain the fermentation room temperature within 30–37 °C and humidity within 70% to 74%,Based on these tests, the system demonstrated good performance in automatically adjusting actuator operation in response to environmental changes, ensuring a stable fermentation process. Keywords: ESP32, DHT22, HX711, load cell, fuzzy logic, IoT, temperature, humidity, weight control Penelitian ini bertujuan untuk merancang dan membangun sistem monitoring suhu dan kelembapan pada proses fermentasi tempe menggunakan metode logika fuzzy Mamdani. Sistem ini dibuat untuk memantau kondisi ruang fermentasi secara real-time dan mengendalikan perangkat pemanas (lampu) serta pendingin (peltier dan kipas) agar suhu dan kelembapan tetap berada pada rentang yang optimal. Perangkat keras yang digunakan meliputi mikrokontroler ESP32, sensor suhu dan kelembapan DHT22, load cell HX711, LCD 16x2 I2C, serta modul relay untuk mengontrol aktuator. Metode pengendalian menggunakan logika fuzzy Mamdani dengan tiga input, yaitu suhu aktual, kelembapan aktual, dan setpoint suhu, serta tiga output berupa kecepatan kipas, intensitas kerja peltier, dan status lampu pemanas. Selama pengujian, suhu ruang fermentasi tercatat berada pada rentang 30–37 °C, sedangkan kelembapan berada pada kisaran 70% hingga 74%,, yang sesuai untuk mendukung proses fermentasi tempe.proses menunjukkan terjadinya fermentasi secara normal. Data hasil pembacaan sensor ditampilkan pada LCD dan dikirim ke aplikasi Blynk untuk pemantauan jarak jauh melalui smartphone. Hasil pengujian menunjukkan sistem mampu mempertahankan suhu ruang fermentasi dalam rentang 30–37 °C dan kelembapan 70% hingga 74%, Berdasarkan pengujian tersebut, sistem ini menunjukkan kinerja yang baik dalam menyesuaikan kerja aktuator secara otomatis terhadap perubahan kondisi lingkungan, sehingga proses fermentasi berlangsung stabil Kata Kunci: ESP32, DHT22, HX711, load cell, logika fuzzy, IoT, suhu, kelembaban, kontrol berat
