Abstract

Dalam proses pembuatan roti, ada salah satu proses dalam tahapannya yang disebut proofing. Istilah proofing sendiri ialah mengistirahatkan atau adonan dibiarkan pada suhu dan kelembaban tertentu (fermentasi). Pada proses proofing, adonan roti akan mengembang dengan baik pada rentang suhu 27-40⁰C dengan kelembaban 75-85% RH. Pada Laboratorium Teknologi Proses Agro belum menggunakan proofer yang dapat dimonitoring secara jarak jauh. Hal tersebut agak menyulitkan untuk melakukan pemantauan pada saat praktikum terhadap proses proofing pada roti, sehingga kualitas pada roti belum bisa konsisten. Untuk menyelesaikan permasalahan tersebut, maka pada penelitian ini diusulkan suatu alat yang dapat dimonitoring suhu dan kelembaban serta dapat memberikan peringatan pada suhu tertentu menggunakan aplikasi Arduino IoT Cloud. Penelitian ini bertujuan memonitoring suhu dan kelembaban serta Memberi peringatan pada suhu tertentu pada alat pengembang roti (proofer) menggunakan Arduino Iot Cloud. Metode yang digunakan dalam penelitian ini adalah dengan perancangan alat sebuah sistem dengan menggunakan DHT22 sebagai pendeteksi suhu dan kelembaban, buzzer dan led sebagai indikator, RTC sebagai penghitung waktu, serta mikrokontroler ESP32. Dari hasil penelitian didapatkan rata-rata error pada suhu  0,34% dan kelembaban 0,75% dari perbandingan  Temperature and Humidity Meter dengan sensor DHT22. Penggunaan proofer pada saat praktikum dilaboratorium teknologi proses agro dapat dimonitoring secara jarak jauh suhu dan kelembabannya, serta mendapatkan peringatan berupa alarm menggunakan led dan buzzer pada suhu 25°C - 36°C agar kualitas pada roti bisa konsisten.

Abstract

Lack of understanding regarding electrical power usage is a common problem that often occurs. Consumers only know the amount of electricity used when they receive their monthly bill, which often causes confusion or dissatisfaction with the bill value which is considered unreasonable or too high. The aim of this research is to monitor electrical energy usage in real time and be able to display the costs of electrical energy usage. This protection system is designed using the PZEM-004t current sensor and ESP-32 microcontroller package. The reading of electrical quantities (voltage, current, active power, energy) carried out by the PZEM-004t sensor is then sent to the microcontroller, on the microcontroller the value of the electrical quantity is converted into rupiah prices and displayed on the LCD display. Monitoring via smartphone is made using a simple application creation platform, namely MIT App Inventor, connected to the internet network with a microcontroller so that electrical energy use can be monitored via smartphone. The test results show that the tool that has been created is capable of displaying the cost of electrical energy usage in accordance with the electricity tariff calculation of 900 Watts. and has a voltage measurement accuracy level of 99.4% and a current measurement accuracy level of 92.1%. If an overcurrent or short circuit occurs, the relay will disconnect the load from the PLN source. This condition will remain Off until the load returns to normal. If the load is reduced until the current is below the nominal current value of the current sensor that has been set, the relay will reconnect and the system will return to normal. In abnormal circuit conditions, before the relay breaks the circuit, the buzzer will sound.

Abstract

The fermentation process of cocoa beans is a critical stage in chocolate production that affects the final quality of the product. To ensure that fermentation takes place optimally, monitoring parameters such as temperature, humidity, and pH is necessary. This research aims to develop and validate an Internet of Things (IoT)-based data acquisition system that uses ESP32 and MQTT protocols to monitor the fermentation process of cocoa beans. The system consists of an ESP32 module connected to DHT22 sensors to measure temperature and humidity, and a pH meter to measure acidity. The data collected by the sensors is sent in real-time via a wireless connection to an MQTT broker, where it can be monitored continuously. System testing was conducted in a small-scale fermentation environment. Validation results show that the system is capable of providing accurate and consistent data when compared to manual measurements using standardized tools. The difference between the data collected by the system and manual measurements was within acceptable tolerance limits, indicating that the system is reliable enough to be used in small-scale applications. The system also demonstrated fast response to changes in fermentation conditions, and stable data connection with minimal latency via the MQTT protocol. The developed data acquisition system has successfully acquired data and validated it using standard measuring instruments. The average data error for the pH sensor is 2.78%, temperature sensor 1.41%, and humidity sensor 1.94%. These error values indicate that the performance of the sensors used is good.

Abstract

Passion fruit has a distinctive sweet and sour taste, which is quite popular in Indonesia, especially in South Sulawesi. Passion fruit is processed into syrup, and dodol is one of the typical souvenirs popular with tourists. Processing passion fruit syrup in the Micro, Small, and Medium Enterprises (MSMEs) Industry still uses very simple equipment. Hence, the quality and quantity of the product produced are not optimal. Passion fruit cutting uses a knife with a low capacity for cutting and shrinkage results, so this research aims to design a passion fruit-filled shaver machine based on a microcontroller and electro-pneumatics. This passion fruit shaver machine uses a microcontroller as the control center. First, the passion fruit passes through an infrared sensor, which detects the fruit and counts the number of incoming fruits. After that, Arduino Uno reads and activates the control relay from the DC motor. After 0.5 seconds, cylinder 1 is active, which pushes the DC motor down so that the passion fruit shrinks for 3 seconds. Then, the pneumatic push up to the normal position; after 0.5 seconds, the second cylinder actively pushes the passion fruit skin that has been shaved out (thrown away). This processes for 1 second and returns to its normal position. If there is passion fruit, it comes in again, and the tool functions similarly, and so on. The results of this study produced a passion fruit shrinker machine with dimensions of length 300 mm x width 300 mm x height 600 mm, a motor power of 240 Watt or 0.321 HP, and a production capacity of 54 kg/hour.
