Abstract

The proofing process is an essential step in bread-making, where the dough is allowed to rest for the gas content to develop and form a soft structure. However, many small-scale bread producers still rely on manual methods for proofing, leading to unstable temperature and humidity levels and longer production times. This study focuses on developing an electrical system for a bread proofer that can stabilize temperature and humidity during the proofing process. The system includes an Arduino Mega microcontroller with a DHT22 sensor for real-time temperature and humidity detection, an I2C LCD for monitoring, and a potentiometer for setting the desired temperature and humidity values. To achieve stability, a PID control system is used. The results show that the system can stabilize at a temperature of 40.10oC and humidity at 80-90RH for approximately 38.4 minutes. This electrical system offers an effective solution for optimizing the proofing process in bread production.

Abstract

Company X is a paving block molding machine fabrication company in Surabaya. However, the machine still has some shortcomings because it is still conventional or manually operated. Some of these shortcomings, such as being still prone to human error and being less consistent when operating, can affect the results of the amount of production. From this phenomenon, automation is very important in the industrial world. Therefore, by referring to previous phenomenon, through this research, an automatic control system is made on paving block molding machine using PLC. The results showed that PLC succeeded in developing a system that works automatically on the machine. Then, the ladder diagram used several instructions, including interlock, timer, counter, and set reset according to how the machine works. Then, the PLC-based automatic control system has a shorter cycle time than the original manual machine. Cycle time has decreased by 15.4%. From this decrease in cycle time, if simulated related to production capacity, an automatic control system can increase production per hour by 300 pcs more than the manually operated machine.
