Abstract

An application product is said to be of quality if it meets the standards required by an internationally agreed organization. ISO 25010 is an international organization that issues standards to measure the suitability quality of an application or software developed by individuals or organizations. Getting to Know Wayang Sasak Characters is a software product designed as an Android-based augmented reality application. Therefore, the application Getting to Know Sasak Wayang Figures needs to be evaluated to determine its quality and suitability. This article aims to convey two test results of the characteristics contained in ISO 25010, namely functional suitability and performance efficiency. Functional suitability characteristics were tested using the black box method. The data collection technique was carried out using test cases. The results of the test case data processing are then calculated using the feature completeness matrix. Next, for performance efficiency characteristics, calculate the distance of the marker to the smartphone camera with the help of a ruler. Next, to find out the performance during the initial launch of the application, use the Firebase Lab Test tool. Test results for functional suitability characteristics, based on the feature completeness matrix, obtained a result of X = 0.87. These results show that the Getting to Know Sasak Wayang Characters application can run optimally even though there are still several features that are not functioning as expected. The results of performance efficiency testing by measuring market distance can detect markers up to 80 cm. The initial launch time for the application was obtained in 45 seconds using the Firebase Lab tools. The results of this research can then be used as a reference for developing the Getting to Know Sasak Wayang Characters application.

Abstract

Learning media is an important part of producing quality learning. Therefore, learning media development is needed that supports the learning objectives. Several models can be used in designing learning media, such as the ADDIE and ASSURE models. The ADDIE model has the following development steps: (1) Analysis, (2) Design, (3) Development, (4) Implementation, and (5) Evaluation. While the ASSURE model has the following development steps: (1) Analyzing learners, (2) Stating learning objectives, (3) Selecting media and methods, (4) Utilizing media and methods, (5) Requiring learner response, (6) Evaluating. The purpose of this study is to compare the use of the ADDIE model and ASSURE model according to the learning objectives. The research was conducted using the literature review method from 36 articles and books that discuss the making of learning media with ADDIE and ASSURE design models. The literature review references were taken from Google Scholar with publication years between 2012 - 2022. The results of this study show that the use of the ADDIE design model is more effective in designing learning media applications because it focuses on material content and application feasibility so that students can use it optimally to achieve goals. Meanwhile, the ASSURE model is more effective for designing learning systems or teaching materials because itfocuses on the application of learning media design models that can attract student interest to generate learning motivation.

Abstract

Feature selection is a critical step in enhancing the accuracy and efficiency of machine learning models, particularly in the field of human activity recognition (HAR) using smartphone sensor data. This research explores the use of Binary Particle Swarm Optimization (BPSO) to reduce the dataset's dimensionality while retaining essential information. Out of 90 initial features, BPSO successfully selected 34 optimal features. These features were then used to train various machine learning models, achieving exceptional classification performance. The Random Forest algorithm achieved the highest accuracy at 99,92%, followed by K-Nearest Neighbour (KNN) at 99,08%, Support Vector Machine (SVM) at 98,68%, Multi-Layer Perceptron (MLP) at 96,01%, Decision Tree (DT) at 95,07%, and Naïve Bayes (NB) at 68,69%. The accuracy of all these algorithms exceeded the accuracy of the same algorithms without PSO-based optimization, as reported in previous studies used as baselines, except for Naive Bayes. These findings highlight the effectiveness of BPSO in feature selection for HAR tasks and its capability to improve machine learning model performance in practical applications.

Abstract

This research addresses the lack of cultural sensitivity in existing Adaptive User Interface (AUI) frameworks, which predominantly rely on Western-centric paradigms and often overlook the collective and spiritual dimensions of student well-being. To bridge this gap, this study proposes a conceptual ontology framework that operationalizes the Indonesian Wellbeing Scale (IWS) into computational adaptation logic for mobile learning applications. Adopting a Design Science Research approach utilizing the NeOn methodology, we formally modeled multidimensional context factors—specifically spiritual observances, social relations, and self-acceptance—into a machine-readable semantic taxonomy. The proposed ontology was rigorously validated using a two-tiered verification strategy: logical consistency checking via the HermiT reasoner and functional validation through Competency Questions (CQs) mapped to SPARQL queries. The results demonstrate that the framework successfully infers complex user needs and triggers appropriate interface adaptations, such as prioritizing community interactions during social isolation or scheduling spiritual alerts, without logical conflicts. This study contributes a validated computational model for Culturally-Adaptive User Interfaces, providing a robust semantic foundation for future physical implementation and empirical user evaluation.

Abstract

Credit card fraud is a significant threat in the financial industry, causing significant financial losses annually, posing a challenge to both businesses and the financial sector. This requires research and development to identify fraud models that significantly improve over time. The purpose of this research is to develop a machine learning (ML)-based credit card fraud detection system with an ensemble approach to address the challenges of imbalanced data in digital financial transactions. The method used includes four main stages: data collection; SMOTE; Hyperparameter Tuning; and model evaluation. The dataset used is from Kaggle Credit Card Fraud Detection, which has a very low fraud proportion (0.17%). The increase in data volume was carried out using SMOTE on the training data. Three main models (Logistic Regression, Support Vector Classifier, Random Forest) and ensembles (hard and soft voting) were tested with hyperparameter tuning for optimal results. Random Forest performed best with an F1-Score of 0.8482 and an ROC-AUC of 0.9684. This model was able to detect 84% of fraudulent transactions with high precision, surpassing other models in handling imbalanced data. The combined advantages of RF and SMOTE are effective for fraud detection which is relevant for real-time systems in the financial sector.

Abstract

Diabetic Retinopathy (DR) merupakan salah satu komplikasi serius akibat diabetes melitus yang dapat menyebabkan kebutaan jika tidak dideteksi dan ditangani secara dini. Deteksi otomatis berbasis citra fundus retina telah menjadi fokus utama dalam penelitian deep learning. Namun, fitur-fitur kecil seperti mikroaneurisma dan lesi halus seringkali sulit dikenali, terutama pada citra dengan kualitas rendah. Penelitian ini mengusulkan modifikasi arsitektur EfficientNetV2 dengan menambahkan dilation layer guna meningkatkan kemampuan model dalam menangkap fitur kontekstual dengan cakupan spasial yang lebih luas tanpa menambah kompleksitas secara signifikan. Dilated convolution memungkinkan perluasan receptive field tanpa mengurangi resolusi spasial, sehingga lebih efektif dalam mendeteksi fitur-fitur kritis pada DR. Pengujian dilakukan menggunakan dataset APTOS 2019 Blindness Detection yang menyediakan citra fundus retina beranotasi untuk lima tingkat keparahan DR. Model dilatih menggunakan optimizer Adam dengan learning rate sebesar 0,001 untuk mencapai konvergensi yang optimal. Evaluasi dilakukan terhadap beberapa varian EfficientNetV2, yaitu B0, B1, B2, B3, dan S. Hasil eksperimen menunjukkan bahwa model EfficientNetV2-B0 dan B1 memberikan akurasi terbaik, masing-masing sebesar 97,14%. Di antara keduanya, EfficientNetV2-B0 menghasilkan nilai presisi dan f1-score yang lebih tinggi. Temuan ini menunjukkan bahwa integrasi dilation layer pada arsitektur EfficientNetV2 berpotensi meningkatkan performa sistem klasifikasi DR otomatis secara signifikan dibandingkan model baseline tanpa modifikasi.   Abstract Diabetic Retinopathy (DR) is a serious complication of diabetes mellitus that can lead to blindness if not detected and treated early. Automated detection based on retinal fundus images has become a primary focus in deep learning research. However, small features such as microaneurysms and subtle lesions are often difficult to identify, particularly in low-quality images. This study proposes a modification to the EfficientNetV2 architecture by incorporating dilation layers to enhance the model’s ability to capture contextual features over a broader spatial range without significantly increasing complexity. Dilated convolutions allow the expansion of the receptive field without reducing spatial resolution, making them more effective in detecting critical features associated with DR. The evaluation was conducted using the APTOS 2019 Blindness Detection dataset, which provides annotated retinal fundus images across five levels of DR severity. The model was trained using the Adam optimizer with a learning rate of 0.001 to achieve optimal convergence. The study assessed several variants of EfficientNetV2 - B0, B1, B2, B3, and S. Experimental results indicate that the EfficientNetV2-B0 and B1 models achieved the highest accuracy, each reaching 97.14%. Among these, EfficientNetV2-B0 yielded higher precision and F1-score values. These findings suggest that integrating dilation layers into the EfficientNetV2 architecture can significantly enhance the performance of automated DR classification systems compared to the unmodified baseline models.

Abstract

Retrieval-Augmented Generation (RAG) represents a growing research direction in the advancement of large language models (LLMs) by incorporating external information sources into the response generation process. As LLM-based systems are increasingly deployed in information-sensitive domains such as healthcare, education, and law, the demand for responses that are not only fluent but also verifiable and context-aware has become more pronounced. This study conducts a systematic literature review (SLR) of 100 recent publications to examine methodological approaches, application domains, technical challenges, and research contributions related to RAG. The review draws on studies indexed in major academic databases, including IEEE, ACM, and Springer, and applies structured inclusion and exclusion criteria to ensure analytical rigor. The findings reveal a strong emphasis on architectural optimization, particularly in the interaction between retrieval and generation components, alongside widespread adoption in domain-specific contexts. Persistent challenges identified across the literature include limitations in retriever effectiveness, system integration complexity, and the absence of standardized evaluation benchmarks. Overall, this review provides a structured synthesis of current RAG research and highlights directions for future investigation and practical deployment..

Abstract

This study aims to assess and compare the performance of three forecasting models—Autoregressive Integrated Moving Average (ARIMA), Seasonal Autoregressive Integrated Moving Average (SARIMA), and Gated Recurrent Unit (GRU)—in predicting car sales in Indonesia. The dataset presents intricate seasonal patterns and non-linear fluctuations, which pose challenges for conventional statistical models. The ARIMA model, suited for linear and stationary data, struggled to capture the complexities of the sales trends. While SARIMA, an enhanced version of ARIMA, aimed to handle seasonal components, it also failed to provide accurate predictions. In contrast, the GRU model, a deep learning-based technique, exhibited the best results in terms of predictive accuracy, with significantly lower values for Mean Squared Error (MSE), Root Mean Squared Error (RMSE), Mean Absolute Error (MAE), and Mean Absolute Percentage Error (MAPE). The results highlight the superior performance of the Gated Recurrent Unit (GRU) model in forecasting car sales. This superiority is reflected in lower error values across all evaluation metrics compared to ARIMA and SARIMA. The GRU model provides accurate forecasts for complex business decision-making
