Abstract

This study aimed to design and develop a website-based *Desa Bersinar* Information System and to evaluate its functionality and usability. The research employed the Rapid Application Development (RAD) methodology, comprising requirements planning, user design, construction, and cutover phases. Data were gathered through observation, interviews, and literature reviews. The system was developed using the Laravel framework and a MySQL database. Functionality was tested using Black Box Testing, while usability was assessed via a Likert-scale questionnaire administered to 10 respondents. Test results indicated that all tested features—including login, reporting, village data, articles, and the gallery—functioned according to the established scenarios. Usability testing yielded a score of 341 out of a maximum of 500 (68.2%), placing it in the "good" category. These results demonstrate that the system is user-friendly and capable of supporting the dissemination of P4GN (Drug Abuse Prevention, Eradication, and Handling) information, as well as the centralized management of data, documentation, and community reports. Consequently, the developed information system can serve as a tool to support the digitalization of *Desa Bersinar* Program management at BNN Trenggalek Regency

Abstract

The performance of a Large Language Model (LLM)-based Text-to-SQL system is heavily influenced by the quality of the user-supplied Natural Language Queries (NLQs). Ill-formed NLQs, such as incomplete, ambiguous, or inconsistent information within the database schema, can generate syntactically valid but semantically incorrect SQL queries. This study aims to develop a rule-based ill-formed NLQ detection system as a pre-processing stage in an Indonesian Text-to-SQL pipeline. The system is built using the Experta library with 15 IF-THEN rules that identify six categories of ill-formed NLQs: insufficient information, multiple interpretations, incomplete conditions, illogical, out-of-schema reference, and unsafe/non-SELECT. After rule-only filtering, a LLaMA 3.2 3B Instruct-based validator is optionally used to examine cases requiring deeper semantic understanding. An evaluation of 202 Indonesian NLQs showed that the Rule-only mode achieved 89.60% Recall, 78.87% Precision, 83.90% F1-Score, and 78.71% Accuracy. False positives were primarily influenced by overly strict rules, while false negatives were dominated by semantic ambiguity. These results demonstrate that the rule-based approach provides a consistent and transparent initial filtering mechanism and can be combined with an LLM-based validator to handle cases requiring more complex semantic interpretation.

Abstract

This study aims to evaluate the ease of interaction for users with motor disabilities on the Grab application using Fitts' Law and Task-Based Performance methods. The study applied a quantitative approach involving 35 people with motor disabilities at LKS Sahabat Kita in Tulungagung Regency as respondents. Data were collected through observation, measuring task completion times, recording success and error rates, and analyzed using Fitts' Law to measure interaction difficulty and Task-Based Performance to evaluate interface effectiveness. The results showed that the Grab application has a low level of interaction difficulty with an Index of Difficulty (ID) value of 1.36–2.00. This finding is supported by a high task completion success rate (85.71%–100%) and a relatively short task completion time, indicating that most application features can be operated well by users with motor disabilities. However, several interface elements were still found to potentially hinder interaction and therefore require improvements to improve accessibility. This study contributes as an empirical basis for the development of application interfaces that are more inclusive and user-friendly for users with motor disabilities.

Abstract

Soal cerita matematika (Math Word Problem/MWP) berperan penting dalam melatih kemampuan penalaran logis siswa Sekolah Dasar. Perkembangan Large Language Model (LLM) telah memungkinkan pembuatan soal secara otomatis, namun soal yang dihasilkan kerap mengandung berbagai jenis kesalahan. Penelitian ini bertujuan: (1) mengembangkan dataset MWP berbahasa Indonesia beranotasi 11 kategori kesalahan secara multi-label; (2) merancang model multi-label classification berbasis IndoBERT dan Feed Forward Neural Network (FFNN) untuk mendeteksi kesalahan secara simultan; serta (3) mengevaluasi kinerja model menggunakan metrik Micro F1-Score, Macro F1-Score, dan Hamming Loss. Dataset dikembangkan melalui error-inducing prompting, menghasilkan 2.517 soal cerita yang dianotasi secara manual oleh dua anotator dengan rasio pembagian 80:20 menggunakan stratified random sampling. Model dilatih selama 40 epoch dengan Binary Cross Entropy loss dan optimizer AdamW. Model optimal diperoleh pada epoch ke-13 dengan validation loss 0,2616. Evaluasi pada testing set menghasilkan Micro F1-Score sebesar 0,7657, Macro F1-Score sebesar 0,7631, dan Hamming Loss sebesar 0,1387. Topic Unsafety mencapai F1-Score sempurna (1,000) dan Misspellings mendekati sempurna (0,986), sementara Grade Mismatch menjadi kategori paling sulit dideteksi (F1 = 0,591). Penelitian ini menyimpulkan bahwa pendekatan multi-label classification berbasis IndoBERT efektif untuk deteksi error pada MWP berbahasa Indonesia.

Abstract

Abstract. The rapid advancement of artificial intelligence has enabled the creation of deepfake content that is increasingly realistic and difficult to distinguish from authentic media. The widespread dissemination of deepfakes on social media, particularly TikTok, has generated diverse public responses due to risks of misinformation, opinion manipulation, and ethical concerns. As one of the most popular platforms in Indonesia, TikTok provides a space for public opinion through user comments. This study aims to analyze public sentiment toward deepfake content on TikTok using a deep learning approach based on the IndoBERT model. The dataset consists of 4,000 Indonesian-language comments collected through web scraping using deepfake-related keywords. Sentiment labeling was conducted using a lexicon-based approach and classified into positive, neutral, and negative categories. The research process includes text preprocessing, data splitting, and IndoBERT fine-tuning. Model performance is evaluated using accuracy, precision, recall, and F1-score. The results show that negative sentiment dominates, indicating public concern over potential misuse of deepfake technology. This study provides insights for policymakers and platform stakeholders.
