Abstract

The widespread adoption of artificial intelligence (AI) in scientific writing has introduced significant challenges in maintaining academic integrity, particularly in higher education environments. This research develops an AI-generated text probability detection system for Indonesian scientific papers using Perplexity and Burstiness linguistic analysis. Perplexity evaluates the uncertainty of a language model in predicting subsequent tokens, while Burstiness analyzes word distribution patterns to distinguish the linguistic characteristics of human-written and AI-generated texts. Unlike existing AI detection approaches that primarily focus on English general-purpose texts, this study emphasizes Indonesian scientific writing by integrating linguistic probability analysis with sentence-level visualization to provide interpretable detection results. The proposed system was developed using Python 3.11, Flask framework, and the Cahya/GPT2-small-indonesian-522M model as the language processing engine. Functional testing using the Black-box method demonstrated a 100% validation rate across all implemented features. AI probability evaluation on the selected test samples achieved 100% classification accuracy; however, further validation using larger and more diverse datasets is required to evaluate the generalization capability of the system. Performance testing showed response times ranging from 1,200–7,800 ms under different load scenarios, with error rates between 0–15%. Usability evaluation using the System Usability Scale (SUS) involving 30 respondents produced an average score of 80.9, categorized as Excellent (Grade A). The proposed system provides an interpretable approach for assessing AI-generated text probability in Indonesian scientific documents and has potential applications in maintaining academic integrity, including supporting the validation of scientific reports in sustainable tourism research and other academic domains.
