Abstract

Baros Information Technology Creative (BITC) is a virtual office service provider based in Cimahi that requires adaptive, engaging, and seasonally contextual user interface (UI) and user experience (UX) support to enhance user appeal and engagement. This study aims to design the UI/UX of BITC’s virtual office e-commerce website with a Christmas theme using the Design Thinking methodology. This approach was selected for its iterative and user-centered nature, enabling in-depth exploration of user needs and the development of contextually relevant design solutions. The design process was carried out through five stages—empathize, define, ideate, prototype, and test—involving five respondents selected through purposive sampling. User requirements were gathered via interviews and surveys, then translated into design concepts visualized through interactive prototypes. Usability testing was conducted using the System Usability Scale (SUS), adapted to suit the seasonal theme context. The test results yielded an average SUS score of 82, categorized as “good” with an “excellent” level of acceptance, indicating that the resulting design is user-friendly, visually relevant, and supports seasonal promotional strategies. This study reinforces previous findings that user-centered design approaches are effective in improving interface quality and user experience, while also offering a novel contribution through the application of seasonal themes within the context of professional digital services.

Abstract

This research developed a two-dimensional (2D) educational game themed on the history of the Megalithic Age in Indonesia for mobile platforms using the Rapid Prototyping method and Unity Engine. The aim was to provide interactive learning media that combines historical narratives with exploration-based game mechanics and puzzle solving. The development process included visual asset design, prototyping, and alpha and beta testing. Beta testing involved 20 respondents from junior high and high school levels, resulting in a satisfaction rate of 71.5% (Agree category) based on the Likert Scale, which indicates positive acceptance of the gameplay and educational content. The limitations of the study include the scope of historical material, which only covers the early Megalithic period, the limited number of respondents, and the difficulty level adjustment, which is not yet optimal for all age groups. Further development is recommended to expand the variety of missions, enrich historical content with the latest research references, and add analytical features to monitor user learning achievements.

Abstract

Advancements in Natural Language Processing (NLP) technology have progressed rapidly, marked by the emergence of various Large Language Models (LLMs) such as ChatGPT, Gemini, and DeepSeek AI. One particularly popular model is DeepSeek AI due to its ability to understand and respond to natural language text more contextually. The increasing popularity of this application is accompanied by a growing number of user reviews, which serve as an important source of data for capturing their experiences and perceptions. This study aims to analyze user sentiment toward the DeepSeek AI application using a deep learning approach. Specifically, the research focuses on evaluating the performance of sentiment classification models in the context of Indonesian-language data, which is relatively limited and imbalanced. The dataset was collected from user reviews on the Google Play Store and categorized into three sentiment classes: positive, negative, and neutral. The method employed is a combination of IndoBERT and Bidirectional Long Short-Term Memory (BiLSTM). IndoBERT is used to generate contextual text representations in Indonesian, while BiLSTM is utilized to recognize sequential word patterns. Experimental results show that this hybrid model achieves an accuracy of 45%, with the highest F1-score of 0.66 in the positive class. Meanwhile, a macro-average F1-score of 0.33 and a ROC-AUC of 0.546 indicate that the model’s performance remains limited in distinguishing the three classes evenly. Nevertheless, the main contribution of this study lies in the development of a new dataset consisting of 1,774 Indonesian-language reviews related to LLM-based applications, which can be used for further research in the field of Natural Language Processing (NLP). The study also demonstrates the effectiveness of integrating IndoBERT and BiLSTM for sentiment analysis of Indonesian text with imbalanced data distribution.
