Abstract

Amidst the rapid development of urbanization and increasing population, the challenges in regional planning and management are increasingly complex, especially in rural areas such as Dawungsari Village. This study aims to map the distribution of small businesses and public facilities, such as places of worship, sports facilities, educational facilities, and other village infrastructure. Data were collected through direct observation and local sources, then visualized in the form of a regional map. This mapping provides a comprehensive representation of the distribution of public facilities and services in the village, and provides a basis for supporting more effective development planning. The evaluation shows that the mapping method used is able to produce relevant information for regional management, although there are constraints related to data accuracy and limited local resources.

Abstract

This study investigates the performance gap between two automatic sentiment labeling strategies one relying on star ratings and the other derived from textual content in classifying application reviews using the K-Nearest Neighbor (KNN) algorithm. Each review is converted into TF-IDF vectors, and the influence of both labeling approaches on the resulting classifier is examined. Performance is evaluated using accuracy, precision, recall, and F1-score to ensure a comprehensive assessment, with the content-based method achieving an accuracy of 0.81, indicating a more reliable outcome than the score-based variant. The score-driven approach shows weaker consistency, largely due to mismatches between numerical ratings and the sentiment conveyed in written text. Despite these findings, the study is limited by its focus on a single application domain and its reliance on a single classical baseline classifier, which may be sensitive to class imbalance. Future work is encouraged to incorporate more diverse datasets, adopt modern text representation techniques such as word embeddings or transformer-based encodings, and explore classification algorithms that better accommodate uneven class distributions.

Abstract

Reliable earthquake notification services in public information applications play a critical role in supporting public awareness and preparedness in seismically active regions. This study examines user complaints about earthquake notification features in the Info BMKG mobile application by analyzing publicly available Google Play Store user reviews. A total of 1,500 reviews were collected and examined, with complaint reviews operationally defined as those with star ratings of 3 or lower. Prior to analysis, the dataset underwent text preprocessing and a balancing procedure to ensure adequate representation of complaint-related content. Topic modeling was conducted using BERTopic, a transformer-based approach that enables context-aware clustering of short, informal text, followed by descriptive temporal analysis to examine variations in complaint occurrence over time. The analytical workflow included text normalization, embedding generation, topic extraction, and temporal mapping of complaint patterns. The results reveal several recurring complaint themes, including delayed or missing notifications, clarity of information, application performance issues, and user responses to system updates. Temporal variations indicate periods of increased complaint activity that align with heightened application usage, reflecting shifts in user engagement rather than direct evidence of system failure. Topic validity was assessed through qualitative inspection of representative reviews to ensure semantic consistency and interpretability. Overall, this study provides a structured, descriptive overview of user concerns regarding earthquake notification services and demonstrates the applicability of topic-level and temporal analysis as an evaluative approach for mobile disaster information applications, without making causal performance claims.
