Abstract

The online ordering system is an important strategy in improving service efficiency and customer loyalty, especially in micro businesses such as Coffee Kane. This study applies the Association Rule Mining (Apriori) algorithm within the CRISP-DM framework to identify customer purchasing patterns and design bundling promotions based on Customer Relationship Management (CRM). The data used is transaction history from the last two months. The analysis results produced a number of significant association rules, such as product combinations with the highest lift value of 31.50. These rules were implemented into the Laravel-based ordering system and automatically displayed to customers. This study shows that this data-driven approach not only improves the effectiveness of promotions but also strengthens customer engagement through an adaptive and personally relevant system.

Abstract

An efficient and accurate recruitment process is crucial for companies to ensure the quality of human resources that support growth and innovation. For Coffee Kane, acquiring the best talent is key to maintaining competitive advantage. However, traditional recruitment methods often face challenges, such as time inefficiency, high operational costs, and limitations in the search for quality candidates. This study proposes a web-based online recruitment system that integrates the TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method. This system is designed to accelerate the selection process, reduce operational costs, and expand the search for candidates without geographical limitations. The implementation of this system has successfully automated the selection process, increased efficiency, and resulted in more accurate, objective, and transparent decision-making in selecting the best candidates.

Abstract

The development of information technology nowadays encourages users to use the software appropriately so that commercial software can be maximally empowered that contribute to the efficiency and effectiveness of the job. To support its work, users use Microsoft's Microsof Excel Office Automation System worksheet commonly used by end users for clerical, repetitive and independent work. Microsoft Excel applications are generally used for office worker, clerical computation and users generally use only a portion of the features of some features owned by the application. In this case, the user can maximize the ability of Excel by creating an interactive pseudo database using only Microsoft Excel, so users can organize data with automated database schema. It is intended for time efficiency and also improves the data security factor of human error in handling data. Keywords: Office Automation System, Pseudo Database, Electronic Worksheet, Automatic

Abstract

Antimicrobial Resistance (AMR) has become a growing threat due to the increase in infections that are unresponsive to conventional therapies. Therefore, the development and optimization of Transformer-based Deep Learning using TabTransformer was employed to model the complex interactions between categorical features. This model was trained to predict antibiotic susceptibility at the individual culture level using the Antibiotic Resistance Microbiology Dataset (ARMD). To address the challenge of highly imbalanced data, the methodology applied includes extensive feature engineering to create historical and clinical variables, as well as the use of Focal Loss during training. After optimization, the final model demonstrated excellent discriminatory ability, with an Area Under the ROC Curve (AUC-ROC) of 0.93 and balanced classification performance, yielding a macro average F1-score of 0.82. Interpretability analysis using SHAP confirmed that patient clinical history and prior drug exposure were the most dominant predictive factors. These findings suggest that the Transformer-based Deep Learning architecture using TabTransformer, combined with clinically relevant feature engineering, can produce a reliable and evidence-based predictive tool

Abstract

Digital marketing has become a critical enabler of organizational transformation, requiring firms to adopt customer-centric strategies and optimize processes in increasingly complex environments. However, the conceptualization and measurement of digital marketing maturity remain inconsistent across the literature. This study addresses this gap by conducting a Systematic Literature Review (SLR) of evolutionary digital marketing maturity models published between 2020 and 2024. Following a four-stage methodological framework—comprising selection and exclusion criteria, database search, quality assessment, and data extraction and synthesis—the review identifies similarities, differences, strengths, and limitations among existing models. The findings reveal that while current models provide useful structures for guiding digital transformation, they lack a precise conceptual definition and standardized measurement framework. The study contributes theoretically by advancing the operationalization of digital maturity and practically by offering executives a framework to assess, benchmark, and monitor progress in digital transformation. Furthermore, it establishes a foundation for future research on the relationship between digital maturity and corporate performance across cultural and regional contexts.

Abstract

The sales of pharmaceutical products among the public are increasing, especially with the recent pandemic that has led to an increase in drug sales. This has created significant potential for the pharmaceutical industry or drug sales businesses. However, proper marketing plans are required in the pharmaceutical industry to optimize revenue. Analyzing drug sales trends can provide valuable insights for creating excellent marketing plans. To develop a superior marketing plan, an analysis of sales transaction data is necessary with the help of data mining, which is useful for obtaining important information from the dataset being analyzed. The Apriori algorithm is used in this research to examine association rule patterns of drug sales in pharmacies The sales information used as dataset is consisting of 600,000 transactional data collected over six years (2014–2019). This dataset includes the date and time of sales, pharmaceutical drug brands, and other relevant information.
