Abstract

The rapid growth of retail transaction data has created new opportunities for businesses to analyze customer purchasing behavior and improve decision-making strategies. Market basket data contains valuable information about product combinations purchased together within a single transaction, which can reveal hidden patterns of consumer behavior. This study aims to apply the K-Means clustering algorithm to segment market basket transaction data based on similarities in purchasing patterns. The research method involves several stages, including data preprocessing, transformation of transaction data into a binary feature matrix, determination of the optimal number of clusters, and clustering analysis using the K-Means algorithm. The results show that the clustering process successfully groups transactions into several clusters representing different purchasing characteristics. Each cluster reflects distinct consumer behavior patterns such as routine household purchases, breakfast-related items, snack-oriented transactions, and fresh product selections. These findings demonstrate that K-Means clustering can effectively identify meaningful patterns within market basket datasets. The clustering results provide useful insights that can support retail strategies such as targeted promotions, product bundling, store layout optimization, and inventory management. Overall, the application of clustering techniques in market basket analysis contributes to improving data-driven decision-making and enhancing the understanding of customer purchasing behavior in retail environments.

Abstract

This study aims to develop an IoMT Rehabilitation System based on the integration of Electromyography (EMG) sensors, embedded Internet of Medical Things (IoMT), adaptive actuators, and ergonomic design to improve the effectiveness of real-time adaptive medical rehabilitation. The study employed a Research and Development (R&D) method using a multidisciplinary approach integrating mechanical engineering, biomedical engineering, and embedded systems. The research subjects consisted of 42 participants, including mechanical engineers, biomedical engineers, rehabilitation physicians, and post-stroke patients with mild to moderate conditions. The research process included mechanical device design, prototype fabrication, EMG and IoMT sensor integration, biomechanical testing, and limited clinical validation. The results showed that the developed rehabilitation system achieved an EMG sensor reading accuracy of 94.2%, improved patient movement efficiency by 28%, and increased device comfort by 31% compared to conventional rehabilitation systems. Furthermore, the implementation of IoMT enabled real-time rehabilitation monitoring through a digital dashboard, allowing medical personnel to evaluate therapy progress more objectively and systematically. The integration of EMG-based adaptive actuators successfully created a closed-loop rehabilitation system capable of providing dynamic movement assistance according to the patient’s physiological conditions. This study contributes to the development of smart rehabilitation engineering based on biomechanics, IoMT, and ergonomic design as a more adaptive, precise, and efficient solution for modern medical rehabilitation.
