Abstract

In the era of the internet’s exponential growth, readers are often overwhelmed by the plethora of books available, particularly in the genre of light novels. This research aims to address this issue by developing a recommendation system for light novels, utilizing a chatbot interface. The methodology employed follows the Borg and Gall model, with a focus on research, information collection, planning, and development stages. The research stage involved the use of questionnaires to gather data and analyze the parameters to be used in the recommendation system. The development stage was carried out using the Scrum methodology and the Retrieval Augmented Generation (RAG) approach for the chatbot’s functionality. The outcome of this study is a web-based online light novel application and featuring a chatbot conversational recommender system. Through this system, users can access and read light novels online, while also utilizing the chatbot to request novel recommendations. The research findings demonstrate the successful integration of Large Language Model (LLM) technology into the web-based light novel application. The Scrum development approach facilitated efficient system creation, and the RAG-based chatbots are seen as successful in producing recommendations that match user queries based on existing knowledge. Recommendation results are obtained from semantic search and from the ranking vector with the highest score.

Abstract

This research investigates the impact of crossword puzzle game teaching media on the vocabulary mastery of seventh-grade students at SMP Negeri 2 Siantar. It utilizes Case's theory for crossword puzzles and Amin & Sumendap's theory for scramble games. Employing a quantitative research method with a quasi-experimental design, the study focused on seventh-grade students during the 2024/2025 academic year. The experimental group was taught using crossword puzzles, while the control group used scramble games. The results revealed that the experimental group had a higher mean score, with a pre-test score of 56.5 and a post-test score of 74.33. In comparison, the control group's pre-test mean was 51.83, which increased to 64.33 in the post-test. A t-test analysis showed a t-test value of 2.35, which is greater than the critical value of 1.67. Consequently, the alternative hypothesis (Ha) was accepted, and the null hypothesis (Ho) was rejected, indicating that the crossword puzzle game had a more significant effect on vocabulary mastery than the scramble game for seventh-grade students at SMP Negeri 2 Siantar.

Abstract

Digital transformation has encouraged organizations to generate large volumes of data that must be managed effectively to support strategic decision-making. Business Intelligence has become a solution for integrating, analyzing, and presenting data into valuable information. This study aims to analyze the implementation of Business Intelligence in digital organizations, its role in supporting data-driven strategic decision-making, as well as the benefits and challenges of its implementation. This study used a qualitative method with a literature review approach by examining journals, scientific articles, and other academic publications related to the research topic. The data were analyzed using descriptive qualitative analysis. The results show that the implementation of BI through data warehouses, dashboards, reporting systems, and data analytics can improve operational efficiency, accelerate access to information, and support performance monitoring and business trend analysis more effectively. BI also supports faster and more accurate data-driven decision-making. Business Intelligence plays an important role in supporting strategic data-driven decision-making in digital organizations. However, its implementation still faces challenges related to data quality, information security, limited human resource competencies, and high technology implementation costs.
