Abstract

Puskesmas is the frontline institution in health services and counseling. In order to give the services usually Puskesmas has management information system (MIS) to support in data processing. The MIS that is used by them should be in top performance to ease the worker finds and work more effectively and efficiently. In order to ensure the MIS always performes, analysis must be conducted to find problems so improvement can be made. Using heuristic evaluation method, an evaluation is carried out based on 10 indicators by distributing questionnaires to the clinician at Puskesmas. Analysis shows that there are 8 problems from 4 heuristic indicators such as visibility of system status, comparison between the system and real world, flexibility and efficiency of use, help and documentation. The problems that were found are considerably small problems with small priority for improvements. Such problems can be use as references for improvements, enhancements and feature additions to the MIS in Puskesmas Depok II, Sleman District and to ease the user.

Abstract

This study aims to conduct an analysis of the management information system implemented at the community health center (Puskesmas). In fulfilling its operational functions, Puskesmas typically utilizes a management information system to support data processing and the delivery of healthcare services. To enable healthcare personnel to perform their duties more effectively and efficiently, the system must operate in an optimal condition. Ensuring such efficiency requires a systematic evaluation to identify existing issues, thereby allowing for targeted improvements and further system development. The evaluation was carried out using a heuristic evaluation approach focused on usability aspects, referencing ten standard indicators. Data were collected through the distribution of questionnaires to clinical staff at Puskesmas. The results of the analysis identified 15 usability-related issues distributed across 4 key usability aspects. These issues were subsequently categorized into low and medium priority levels for improvement. The findings from this study may serve as a foundation for system refinement, feature enhancement, and overall development of the management information system at Puskesmas Depok I, Sleman, ultimately aiming to improve user experience in terms of accessibility and operational convenience.

Abstract

The global environment is facing a serious challenge in the form of increasing plastic waste. Indonesia is one of the world’s largest producers of plastic waste, and Tanjungpinang City faces a similar issue, generating approximately 100–150 tons of waste per day, predominantly plastic waste. A significant portion of this waste originates from marine environments, while its management remains limited by inadequate facilities and technological resources. Therefore, a waste detection solution is needed to improve the efficiency of plastic waste management in the region.. This study aims to evaluate the detection performance of a Faster R-CNN model using pre-trained weights with a ResNet-50 Feature Pyramid Network (FPN) backbone. Experimental results show an mAP@0.50:0.95 of 59.55% and an mAP@0.50 of 82.64%. Further evaluation for each plastic waste category resulted in accuracies of 90% for plastic bottles, 88% for food wrappers, 78% for beverage wrappers, and 86% for plastic bags. These findings indicate that the pre-trained Faster R-CNN model with a ResNet-50 FPN backbone is capable of effectively detecting and classifying different types of plastic waste in marine environments. Consequently, this model has the potential to support more effective waste management and sorting processes in the coastal waters of Tanjungpinang City.

Abstract

Hyperparameter optimization is a crucial process for enhancing the performance of deep learning models, particularly in the context of Indonesian sentiment classification. This study examines the impact of varying learning rates on a long short-term memory (LSTM) architecture trained with the adaptive moment estimation (Adam) optimizer. The dataset comprises 9,295 Indonesian comments automatically labeled by the Indonesian Bidirectional Encoder Representations from Transformers (IndoBERT) model. Stratified k-fold cross-validation was employed to maintain class balance during training. Learning curves were analyzed to evaluate convergence and identify potential overfitting, while early stopping was applied when performance improvements became insignificant. The one-way analysis of variance (ANOVA) test (p-adj = 0.000575 < 0.05) revealed significant differences among the learning rate variations. Post-hoc analysis indicated the learning rates of 0.0001, 0.001, and 0.002 differ significantly from 0.02. Descriptive statistics showed that a learning rate of 0.001 was the most optimal, achieving the highest validation accuracy while maintaining a relatively low variance. Evaluation across two data categories demonstrated that lower learning rates (0.0001 and 0.002) achieved the best accuracy, 78.71% on in-domain data, whereas higher learning rates (0.01 and 0.02) performed better on cross-domain data with 36% accuracy. These findings highlight the crucial role of learning rate selection in determining model stability and generalization capability.

Abstract

Purpose – URL-based phishing remains a persistent cybersecurity threat because attackers continuously generate deceptive links that evade blacklist-based and supervised detection systems. This study aims to develop and evaluate an unsupervised phishing detection framework that learns legitimate URL patterns without requiring labeled phishing samples during training. Design/methods/approach – A hybrid Variational Autoencoder–Convolutional Neural Network (VAE-CNN) model was proposed and compared with a Convolutional Autoencoder (CAE) baseline. Both models were trained only on legitimate URLs from the PhiUSIIL dataset and evaluated using repeated holdout validation across five random seeds. The experiments included four latent dimensions, five percentile-based anomaly thresholds, and McNemar’s exact test. In addition, external validation was conducted using PhishTank phishing URLs combined with PhiUSIIL legitimate holdout samples. Findings – In the main PhiUSIIL benchmark, the best VAE-CNN configuration achieved an accuracy of 0.9458, precision of 0.9091, recall of 0.9907, and F1-score of 0.9482, outperforming the best CAE baseline with an F1-score of 0.8920. In external validation, VAE-CNN achieved an F1-score of 0.9494, compared with 0.8470 for CAE. McNemar’s test confirmed statistically significant paired-prediction differences across all evaluated comparisons. Research implications/limitations – The findings indicate that probabilistic latent modeling improves unsupervised phishing detection, although the study remains limited to character-level URL representations and benchmark-based evaluation. Originality/value – The proposed VAE-CNN provides a statistically validated unsupervised framework for URL-based phishing detection and demonstrates promising cross-source performance under the evaluated PhiUSIIL–PhishTank setting, particularly when labeled malicious URLs are limited, delayed, or rapidly outdated.
