Abstract

The use of information technology in education continues to evolve, including in the analysis of vocational school department selection. This study aims to apply Business Intelligence (BI) to analyze admission opportunities in the most popular departments at SMK Negeri 1 Tanjung Pura. The data used is secondary data from SMK applicants between 2020 and 2024, processed using Tableau software for data visualization. The results indicate that the Motorcycle Engineering and Business department is the most favored choice, while the Accounting department has the fewest applicants. BI implementation enables more accurate and informative data presentation, aiding schools in student admission strategies and providing clearer information for prospective students in choosing a department.

Abstract

Politeknik Negeri Medan, like many higher education institutions in Indonesia, encounters persistent challenges in managing non-academic student activities due to fragmented data repositories, inconsistent reporting mechanisms, and manual administrative workflows. This study proposes the design of a cloud-native Student Activity Management Information System (SAMIS) engineered to streamline the processes of planning, monitoring, verification, and evaluation of extracurricular activities. The system adopts a microservices-based architecture supported by containerization, Kubernetes orchestration, and CI/CD pipelines to ensure scalability, resilience, and operational efficiency. Key functional modules include proposal submission, multi-level review workflows, real-time activity tracking, and centralized document management. Although the system has not yet been implemented, architectural simulations, workflow modelling, and comparative analysis with previous studies indicate strong potential for improving institutional governance and supporting data-driven decision-making. The proposed design also aligns with contemporary digital transformation initiatives in higher education. Future work includes prototype development, pilot testing, and comprehensive user evaluation to validate performance in real-world contexts.

Abstract

Price competition on increasingly competitive e-commerce platforms requires businesses to implement pricing strategies that are adaptive and responsive to market dynamics. Static pricing strategies have proven to be unable to accommodate changes in demand, competitor prices, and consumer perceptions in real-time. This study aims to develop a Dynamic Pricing model based on Deep Reinforcement Learning (DRL) using the Deep Q-Network (DQN) algorithm that integrates the sentiment analysis of consumer reviews with the IndoBERT model and competitor prices obtained through web scraping. The research data was collected from the Tokopedia marketplace in the electronic product category for six months (January-June 2024), including 12,450 product reviews and 3,200 snapshots of competitors' prices from 45 sellers. The fine-tuned IndoBERT model achieved an accuracy of 91.2% and an F1-score of 0.89 in the three-class sentiment classification. The results of the experiment showed that the proposed DQN model increased total revenue by 18.7%, profit margin by 14.3%, and conversion rate by 11.2% compared to the static pricing strategy. This model also outperformed rule-based pricing by 8.1% and Q-Learning tabular by 3.3% in revenue metrics. The Ablation study confirmed that the sentiment feature contributed 6.3 percentage points to the increase in revenue. This study proves that the integration of consumer sentiment signals and competitors' prices within the framework of DRL provides a more optimal and adaptive pricing strategy in the e-commerce environment.
