Abstract

Information is a key to success in communicating. Communication will not be possible without information. But if the information we convey is wrong it will cause a problem. At Raharja University there is a facility that provides needs services to students such as searching for material, printing, scans, and binding documents, there are also accessories and service places if there are students who have problems with the equipment given for study, Raharja Internet Cafe. Raharja Internet Cafe has a website to be used by students who want to order their needs. However, the admin who maintains Raharja Internet Cafe cannot monitor what products or goods are the best-selling or the most sold because they are not well monitored. With no monitoring of the admin sales process or the guard cannot report the goods to the University, or the conventional data recording process. These problems are certainly considered ineffective because Raharja University is engaged in technology in each of its lecture activities. Creating a viewboard on the Raharja Internet Cafe website as a medium for delivering sales information is the solution. The method that I use is a method of data collection namely observation and literature study and a qualitative approach. The results of this study are that the presence of a viewboard on the Raharja Internet Cafe website can facilitate the admin or guard of Raharja Internet Cafe to make a report to the Raharja University.

Abstract

The development of Artificial Intelligence (AI) in Human Resource Management (HRM) provides an opportunity to increase efficiency and effectiveness in the recruitment process in the modern business era. In this context, AI supports the achievement of the Sustainable Development Goals (SDGs), especially goal 8, namely decent work and economic growth, and goal 10 on reducing inequal ity. AI allows companies to optimize the candidate selection process by using sophisticated algorithms that can analyze large amounts of data to find the most suitable candidates for the organization needs. Thus, AI plays an important role in creating a faster, more accurate, and bias-free recruitment process, which ultimately improves the quality of the workforce. However, the application of AI in recruitment also faces challenges related to technology integration, personal data protection, and potential bias in algorithmic decision-making. This study examines the role of AI in optimizing the recruitment process and its contribution to achieving the SDGs. The study also evaluates the impact of AI on recruitment decisions and company productivity and provides recommendations for more effective implementation in modern business.

Abstract

The increasing adoption of gamified systems in workplace settings has garnered significant attention, particularly in multinational enterprises (MNEs) seeking innovative approaches to enhance team member engagement and productivity. Background Gamified attendance systems, integrating game elements such as points, leaderboards, and rewards, present a novel strategy for improving attendance and punctuality across diverse cultural contexts. However, implementing such systems in cross-cultural settings poses unique challenges and opportunities. Objective: This study explores the factors influencing the adoption of gamified attendance systems in MNEs, focusing on cross-cultural adaptability and its implications for organisational performance. Research Method A mixed-methods approach was employed, combining qualitative interviews with HR managers and employees from diverse cultural backgrounds with a quantitative survey targeting 350 employees across 10 MNEs. Data were analysed using thematic analysis and structural equation modelling to identify cultural and organisational determinants of success. Results The findings reveal that cultural dimensions, such as power distance and individualism, significantly impact team member perceptions and engagement with gamified systems. While gamification enhanced attendance rates and morale in low-power-distance cultures, it faced resistance in high-power-distance environments. Additionally, alignment with organisational goals and transparent communication were critical for successful implementation. Conclusion: This study underscores the importance of cultural sensitivity and strategic planning in the cross-cultural adoption of gamified attendance systems. By addressing these factors, MNEs can leverage gamification to foster a more engaged and productive workforce, enhancing global operational efficiency. Future research should explore longitudinal impacts and sector-specific adaptations to optimise implementation outcomes.

Abstract

Database normalization is a key process in relational database design that reduces redundancy and ensures data integrity. As data volumes increase, maintaining efficient and consistent storage becomes critical. This study investigates the application of normalization techniques from First Normal Form (1NF) to Third Normal Form (3NF) on a sample inventory database to evaluate their impact on storage efficiency. The process focuses on eliminating data repetition and optimizing table structures to enhance performance. Experimental results show that normalization reduces database size by approximately 30%, significantly minimizing redundancy. Smaller, more organized tables improve storage utilization, especially in large-scale systems. However, normalization can introduce query complexity due to increased joins, potentially affecting execution time. Despite this, the trade-off is considered acceptable given the gains in data integrity and storage optimization. This research emphasizes the value of normalization for scalable and maintainable systems. It also aligns with Sustainable Development Goals (SDGs), particularly Goal 9 (Industry, Innovation, and Infrastructure) and Goal 12 (Responsible Consumption and Production), by promoting efficient digital infrastructure and responsible data management practices. These improvements contribute to more sustainable, cost-effective systems in industries relying on large-scale data, such as e-commerce, healthcare, and finance. In conclusion, normalization is an essential tool for optimizing storage and ensuring data consistency in relational databases. Although performance trade-offs exist, they can be mitigated through indexing and query optimization. The study offers insights for database designers seeking to balance efficiency and system performance in data-intensive environments.
