Abstract

Digitalization demands the MSME sector, including barbershops, to adopt technology in reservation management and marketing. Many barbershops still use manual systems, causing problems such as irregular queues, service delays, and suboptimal promotions. This study formulates how to design an information system that can integrate reservation and marketing functions into a single web-based platform. The objective is to produce an efficient, secure, and user-friendly information system design for both barbershop managers and customers. The method used is the Design Science Research approach with a waterfall system development model, involving needs analysis, system design, database design, and user interface design. The design results were validated by experts and users with a satisfaction rate of over 85%, indicating that the designed system aligns with the operational needs of barbershops. The conclusion is that the developed information system can enhance operational efficiency and customer experience, and is suitable for implementation in the barbershop service sector of SMEs.

Abstract

Delivery delays pose a major challenge in the e-commerce industry, often leading to decreased customer satisfaction and negatively impacting business operations. In this study, the XGBoost (Extreme Gradient Boosting) algorithm is applied to predict delivery delays based on a dataset containing 96,476 records. These records include various features relevant to the delivery process, such as shipping distance, carrier performance, and order characteristics. The model achieves a high overall accuracy of 93.24%, indicating strong general performance. In particular, XGBoost demonstrates excellent results in predicting on-time deliveries, achieving a precision of 93% and a recall of 100%. However, the model struggles to correctly identify delayed deliveries. The recall for delayed deliveries is 0%, and the F1-score is extremely low at 0.01. This significant discrepancy reveals a critical limitation in the model's performance — the inability to detect minority class cases (delayed deliveries) due to class imbalance within the dataset. The results highlight the importance of addressing data imbalance in predictive modeling for delivery outcomes. When the dataset is dominated by on-time delivery records, the model tends to be biased toward that class, failing to learn the patterns associated with delays. To improve performance, the study recommends integrating class balancing techniques such as SMOTE (Synthetic Minority Oversampling Technique) to generate synthetic samples of the minority class. Additionally, the use of alternative evaluation metrics beyond accuracy — such as precision, recall, and F1-score for each class — is suggested to provide a more comprehensive understanding of model effectiveness. Overall, the study provides valuable insights into the complexities of predicting delivery delays and outlines practical strategies for enhancing future models in e-commerce logistics analytics.

Abstract

The increasing complexity of web-based information systems has raised the demand for high-quality software, making the testing process an indispensable stage in the software development life cycle. One of the most widely used functional testing methods is Black Box Testing; however, its effectiveness is highly influenced by the test case design techniques employed. This study aims to analyze the implementation of Equivalence Partitioning (EP) and Boundary Value Analysis (BVA) within the Black Box Testing method through a literature review approach. The research employed a literature review method with a descriptive qualitative approach using secondary data collected from 15 national and international scientific articles published between 2022 and 2026. The analysis was conducted through the processes of identification, classification, comparison, and synthesis of previous studies discussing the implementation of EP, BVA, and their combination in various web-based information systems. The synthesis results indicate that the Equivalence Partitioning technique is more effective in improving testing efficiency by reducing the number of test cases, whereas Boundary Value Analysis is more effective in detecting validation errors at boundary values. Furthermore, the reviewed studies consistently demonstrate that combining both techniques provides more comprehensive test coverage than using either technique independently, as it achieves a balance between efficiency and effectiveness in the software testing process.
