Abstract

This community service program aims to develop a monitoring system for toddler growth and development through Digital KMS in Lebakwangi Village, Arjasari District, Bandung Regency, by integrating digital technology, improving digital literacy, encouraging active community participation, and utilizing local potential. This program is designed as a response to the limitations of the manual recording system that has been used so far, which often causes data input errors, delays in monitoring, and difficulties in early detection of growth disorders and nutritional problems in toddlers. Through an integrated approach, the activity began with the development of a Digital KMS system that included in-depth needs analysis with all stakeholders—from posyandu cadres and health workers to parents—to identify the constraints of traditional recording and determine the main features that must be included, such as automatic data input, notifications, and an interactive forum dashboard that displays data in real time. The stages of system development include needs analysis, user-friendly interface design, development of reporting and analytics modules, pilot testing in several strategic posyandu, and full implementation integrated with the local health system. This digital KMS application was built using Laravel tools for the backend and React for the frontend. Furthermore, the program improves digital literacy through workshops and technical training held at health centers and facilities, the creation of educational modules in the form of video tutorials, written guides, and interactive materials, as well as ongoing assistance with the formation of a technical support team that is ready to provide assistance in the field. A participatory approach is implemented through community discussion forums and the involvement of community leaders as agents of change to optimize system usage, enhance a sense of ownership, and empower the community to actively participate in system evaluation and improvement. In addition, data-based monitoring and evaluation are carried out by activating interactive dashboards for periodic monitoring, data collection and analysis for early risk identification, and periodic evaluation through surveys and questionnaires to compile evaluation reports as a basis for system improvement. Synergy among partners, involving local governments, educational institutions such as Telkom University, and local communities, strengthens the ecosystem supporting this program through strategic collaboration that ensures policy support, material development, and ongoing assistance. By utilizing existing geographical and infrastructure potential as well as the cultural value of mutual cooperation, this program has successfully implemented and socialized a digital KMS application that is expected to not only improve the accuracy and effectiveness of health monitoring for toddlers, but also empower the community through increased digital literacy and sustainable digital transformation, thereby generating a long-term positive impact on the quality of health services and the quality of life of children in Lebakwangi Village.

Abstract

This study examined the effect of local wisdom–based digital learning media on elementary students' national insight while controlling for digital readiness. A quasi-experimental matching-only pretest–posttest control group design was employed. Participants were selected through purposive sampling from one public primary school, yielding 54 Grade V students. To reduce selection bias, students were matched on pretest national insight scores, prior academic achievement, and gender distribution, yielding equivalent experimental (n = 27) and control (n = 27) groups. Data were collected using a 20-item National Insight Test (? .80) and an 18-item Digital Readiness Scale assessing technological competence, attitudes, and self-efficacy (? .80). The intervention lasted four weeks, with the experimental group receiving culturally grounded digital instruction and the control group receiving conventional instruction. Data were analyzed using Analysis of Covariance (ANCOVA), with posttest national insight as the dependent variable and digital readiness as a covariate. Assumption tests were satisfied (p .05). The overall model was statistically significant, F(2, 51) = 14.87, p .001, explaining 37% of variance in posttest scores (R² = .37). Digital readiness significantly predicted national insight, F(1, 51) = 18.42, p .001, partial ?² = .27, while instructional condition showed a smaller but significant effect, F(1, 51) = 4.36, p = .041, partial ?² = .08. The findings suggest that although culturally grounded digital media enhances national insight, students' digital readiness plays a more substantial role in determining learning outcomes.

Abstract

Text-to-SQL systems translate natural language questions into executable SQL queries, allowing users without SQL expertise to access structured data stored in relational databases. Although Large Language Models (LLMs) have substantially improved SQL generation capabilities, many state-of-the-art Text-to-SQL approaches continue to rely on cloud-based models with high computational requirements. Such dependence limits their deployment in environments with limited computing resources. This study addresses this limitation by proposing schema-guided prompting strategies for Text-to-SQL generation using local LLMs. A chat-based application was developed using the Django Web Framework, while model inference was performed through the Ollama platform to enable the deployment of local LLMs. The proposed framework incorporates database schema information, including table structures and column attributes, into structured prompts to improve the alignment between natural language questions and SQL generation. Experiment results across multiple databases demonstrate that schema-guided prompting significantly improves Text-to-SQL performance. The highest accuracy was achieved by LLaMA 3 (8B) with objective-aware prompting, reaching an Exact Matching (EM) accuracy of 71.96%. These findings suggest that structured prompt engineering provides a practical alternative to model fine-tuning for locally deployed LLMs, offering an effective balance between SQL generation accuracy, computational efficiency, and data privacy. Future work will investigate fine-tuning strategies, example selection methods, and cross-domain evaluation to enhance SQL generation.

Abstract

Lung diseases remain a major global health concern, necessitating accurate and timely diagnosis. Chest X-ray (CXR) imaging is widely used but challenging to interpret due to overlapping radiographic features and subjective variability among radiologists. Deep learning approaches, particularly Convolutional Neural Networks (CNNs), have shown promise but are limited in capturing global spatial dependencies. Vision Transformers (ViTs) overcome this limitation through self-attention, making them increasingly attractive for medical image analysis. This study systematically evaluates 13 Transformer-based architectures across three CXR datasets with distinct tasks: Pneumonia (3-class: Normal, Bacterial, Viral), COVID-QU-Ex (3-class: Normal, Non-COVID Pneumonia, COVID-19), and Tuberculosis (2-class: Normal, Tuberculosis). All models were trained under a unified setup with consistent preprocessing, augmentation, and evaluation protocols. To improve robustness, a soft voting ensemble of the top five models was also implemented. Results demonstrate that Transformer-based models provide highly competitive performance. On the Pneumonia dataset, the ensemble achieved an accuracy of 0.8743 and F1-score of 0.8615, surpassing several single models such as DeiT-Base (F1 = 0.8725). On COVID-QU-Ex, the ensemble soft voting obtained 0.9593 accuracy and 0.9582 F1-score, effectively balancing precision and recall. On Tuberculosis, ViT-B/16 and MobileViT-S achieved perfect performance (F1 = 1.0), likely influenced by dataset imbalance. These findings highlight the clinical potential of Transformer-based models, particularly when combined through ensembles, for robust and accurate CXR classification.

Abstract

Automated interview systems powered by artificial intelligence often rely on fine-tuned models and annotated datasets, limiting their adaptability to new leadership competency frameworks. Large language models have shown potential for generating questions and assessing answers, yet their zero-shot performance, operating without task-specific retraining remains underexplored in leadership assessment. This study examines the zero-shot capability of two models, Qwen 32B and GPT-4o-mini, within a multi-turn self-interview framework. Both models dynamically generated questions, interpreted responses, and assigned scores across ten leadership competencies. Professionals representing the role of Digital Marketing and Account Manager participated, each completing two AI-led interview sessions. Model outputs were evaluated by certified experts using a structured rubric across three dimensions: quality of behavioral insights, relevance of follow-up questions, and fit of assigned scores. Results indicate that Qwen 32B generated richer insights than GPT-4o-mini (mean = 2.86 vs. 2.62; p less than 0.01) and provided more differentiated assessments across competencies. GPT-4o-mini produced more consistent follow-up questions but lacked depth in interpretation, often yielding generic outputs. Both models struggled with accurate scoring of candidate responses, reflected in low answer score ratings (Qwen mean = 2.35; GPT mean = 2.21). These findings suggest a trade-off between insight richness and scoring stability, with both models demonstrating limited ability to fully capture nuanced leadership behaviors. This study offers one of the first empirical benchmarks of zero-shot model performance in leadership interviews. It underscores both the promise and current limitations of deploying such systems for scalable assessment. Future research should explore competency-specific prompt strategies, fairness evaluation across demographic groups, and domain-adapted fine-tuning to improve accuracy, reliability, and ethical alignment in high-stakes recruitment contexts.

Abstract

Polycystic Ovary Syndrome (PCOS) is commonly assessed with ovarian ultrasonography, but speckle can conceal follicular margins and reduce the robustness of automated interpretation. Although automated PCOS studies increasingly employ machine learning, the contribution of conventional despeckling to subsequent segmentation and classification has not been examined consistently. This study compares five classical filters - Mean, Median, Lee, Frost, and Kuan - within an interpretable machine-learning pipeline for ovarian ultrasound analysis. From a public collection of 12,680 images, a balanced sample of 300 scans (150 PCOS and 150 non-PCOS) was selected. Two radiologists produced follicle annotations, and disagreements were resolved with a third expert to obtain consensus masks. Each filtered image was segmented by adaptive thresholding with morphological refinement, after which geometric and intensity descriptors were extracted. Support Vector Machine (SVM), Random Forest (RF), k-Nearest Neighbors (k-NN), and Logistic Regression (LR) were trained using a stratified 70/30 train-test split with cross-validated hyperparameter tuning. The Kuan-LR configuration yielded the strongest result, reaching 94.44% accuracy and an AUC of 0.98, together with the best edge-preservation score and segmentation agreement. The results indicate that preprocessing materially affects the reliability of an interpretable PCOS detection pipeline and provide quantitative guidance for selecting a speckle-reduction strategy before segmentation and classification.
