Abstract

Coffee is an important commodity for Indonesia. This huge potential must be utilized optimally. One of the important stages in processing coffee beans is the process of roasting coffee beans. This research focuses on optimizing PID control parameters on coffee bean roasting equipment. The main stages in determining PID control parameters are carried out using MATLAB's PID Tuner and also the process of improving the parameter values. From this research it can be concluded that the PID parameters to improve the temperature control performance of coffee roasting equipment, in the temperature ranges of 210 °C, 215 °C, 220 °C, 225 °C, and 230 °C indicate that the PID parameters have been improved (Kp = 5, Ki = 0.017, and Kd = 2) has better performance compared to parameters obtained directly from PID Tuner Matlab (Kp = 33.4, Ki = 1, and Kd = 4.74). Parameters that have gone through the refinement process show a fairly fast rise time (123 seconds), small overshoot (2.8 °C) and no significant oscillations occur in the system. Thus, it can be concluded that the use of refined PID parameters is more optimal for controlling temperature in coffee bean roasting equipment, because it produces a better system response. By improving the PID parameter values, it is hoped that it can produce roasted coffee beans with accurate variations in maturity levels, so that users can determine the desired taste and aroma characteristics of coffee based on the maturity level.

Abstract

In the era of Industry 4.0, the demand for manufacturing systems that are fast, precise, and efficient has become increasingly urgent. This drives the adoption of artificial intelligence (AI) technologies as a promising solution, including in the field of automatic bottle sorting. However, many industries still use manual bottle sorting systems, which often have significant drawbacks. This study presents an integrated artificial intelligence (AI)-based inspection model for automated bottle inspection in the context of smart manufacturing. The proposed approach integrates geometric feature extraction with region-of-interest (ROI)-based statistical image analysis to improve classification accuracy and robustness. Geometric features extracted from bottle contours are combined with optimized ROI selection to enhance feature relevance prior to classification using a Random Forest algorithm. The dataset consists of four bottle types: plastic, glass, cans, and cardboard, captured under controlled imaging conditions. Experimental results show that the proposed integrated method achieves classification accuracy ranging from 96% to 97.72%. The findings confirm that ROI optimization significantly influences statistical feature characteristics and improves overall model performance. This integrated framework is suitable for implementation in automated visual inspection systems supporting Industry 4.0 applications.
