Abstract

The 2025 Indonesian rice scandal highlighted major shortfalls in food security and the pressing need for robust, data-based verification of authenticity. The goal of this work is to design a fast, lightweight, and fully offline rice grain classification and verification system that can run directly on consumer mobile hardware. The basic idea to overcome the technical bottleneck of deploying complex computer vision models on edge devices is to use macOS and Apple’s unified ecosystem as a rapid prototyping and deployment platform. The deliberate avoidance of fragmented and high-latency workflows such as external environments (e.g. TensorFlow or PyTorch) and intermediate formats (e.g. ONNX) is mentioned. The study contributes a streamlined pipeline that incorporates an Image Feature Print V1 feature extractor, natively trained with Create ML on a publicly available dataset of 75,000 balanced images of five rice varieties (Arborio, Basmati, Ipsala, Jasmine, and Karacadag), directly into a native iOS application built with SwiftUI. The novelty of this approach is the usage of native tools like VisionKit and Core ML, which enables the complete elimination of third-party bridging code that normally bloats the binary overhead. The results show excellent edge efficiency on an iPhone 15 with a median prediction rate of 2.75 ms, an initial load time of 0.54 ms and a compilation latency of 3.66 ms. Moreover, the results reveal that by employing aggressive data augmentations, including the addition of visual noise, blur, exposure adjustment, flipping and rotation to ensure robustness, and by deliberately not cropping to preserve absolute grain dimensions, the model achieved a remarkable overall accuracy of 97% with an ultra-compact deployment footprint of only 66 KB. These metrics demonstrate that a fast, fully offline and privacy-preserving verification system is well within reach with modern consumer hardware.

Abstract

Live streaming has emerged as an essential tool for e-commerce, allowing sellers to engage with potential customers in real-time. However, the massive influx of comments during these sessions often includes a mix of useful product-related queries and irrelevant or distracting messages, which can overwhelm the presenter and reduce the effectiveness of the stream. In this paper, we propose LyFy, a browser-based extension designed to filter live chat messages and provide personalized product recommendations in real-time, specifically applied in Batik e-commerce to support the preservation and promotion of this unique cultural heritage of Indonesia. Our system uses a combination of natural language processing (NLP) and machine learning models to identify relevant comments, group similar queries, and offer product suggestions based on viewers' interests. We demonstrate the effectiveness of this system through a prototype implementation and evaluate its performance with qualitative feedback from streamers and users. The evaluation results indicate high user satisfaction, with over 51% of respondents rating LyFy as highly effective and 52% as highly efficient, making it a valuable tool for enhancing e-commerce live streaming interactions.

Abstract

Background: The rapid digitalization of critical infrastructure has increased exposure to cyber threats. While research on cybersecurity governance is growing, the mechanisms linking behavioral cybersecurity culture to sustained resilience, particularly in high-availability digital infrastructure like data centers, are underexplored. This study addresses this gap by exploring how Digital Risk Culture (DRC) drives Sustainable Cybersecurity Transformation (SCT) and generates Cyber Resilience Advantage (CRA), with Organizational Risk Response Habit (ORRH) as a boundary condition. Objective: The study investigates how DRC impacts CRA through SCT and examines the moderating role of ORRH. It uses Resource Advantage Theory to conceptualize DRC as behavioral capital, SCT as an orchestration mechanism aligned with the NIST Cybersecurity Framework, and CRA as a resilience-based outcome. Methods: A quantitative approach using Partial Least Squares Structural Equation Modeling (PLS-SEM) tested the hypotheses with data from 125 cybersecurity decision-makers in Indonesian data centers. PLS-SEM was chosen for its predictive modeling capabilities and ability to handle interaction effects. Results: Findings show DRC significantly influences SCT (beta = 0.499, p < 0.001), and SCT strongly enhances CRA (beta = 0.735, p < 0.001). ORRH negatively moderates the DRC-SCT relationship (beta = -0.120), indicating that excessive routinization can weaken adaptive transformation. The model explains 30.5 percent of the variance in SCT and 54.0 percent in CRA. Conclusion: This study highlights that DRC strengthens SCT, which enhances CRA in Indonesian data centers. The non-significant moderating effect of ORRH suggests formal governance mechanisms may counter routine reactivity, offering insights for CIOs and risk managers in fostering resilience-oriented transformation.

Abstract

This study analyzes the influence of digital marketing on purchase intention in the premium property industry, examining the mediating role of brand image, perceived product quality, perceived service quality, and customer satisfaction. Using an explanatory quantitative approach, data were collected via an online questionnaire from 110 prospective Developer C consumers categorized as qualified leads who had completed a site visit. Saturated (total) sampling was applied, and data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) in SmartPLS 4.0. Results show that digital marketing has a positive and significant effect on brand image, perceived product quality, and perceived service quality in the pre-purchase phase. However, in shaping customer satisfaction, only perceived product quality emerges as the dominant functional determinant and the sole significant mediator; brand image and perceived service quality fail to mediate the relationship, as premium property consumers evaluate them merely as minimum hygiene factors. Customer satisfaction, in turn, significantly mediates the relationship between perceived product quality and purchase intention, but not the paths from brand image or service quality. These findings confirm that in high-involvement industries, purchase intention is driven by functional satisfaction with the product's physical quality rather than emotional preference for the developer's reputation. Developer C management is therefore advised to prioritize product quality control and maintain consistency between digital information visualization and physical reality during site visits to minimize gaps in consumer expectations.

Abstract

This study investigates the determinants of retired customers’ intention to use Movin mobile banking at Bank Mandiri Taspen by applying the Unified Theory of Acceptance and Use of Technology (UTAUT) and examining the role of trust as a mediating variable. Using survey data from 100 retired users and analyzing the data with PLS-SEM, the study finds that performance expectancy and facilitating conditions are the primary drivers of usage intention. In contrast, effort expectancy and social influence do not significantly influence intention. Interestingly, trust does not directly affect intention and does not mediate the relationship between UTAUT constructs and intention to use. These findings suggest that, among retirees, adoption decisions are shaped more by tangible benefits and practical support than by psychological trust mechanisms. The study contributes to the refinement of UTAUT in elderly contexts and offers strategic recommendations for designing user-centered digital banking services tailored to retirees

Abstract

User reviews for the Instagram application represent a vast and unstructured data source, offering valuable insights into public sentiment. However, their sheer volume and informal linguistic nature necessitate efficient and accurate automated analysis. This study conducts a comprehensive comparative analysis of three prominent Transformer-based models: BERT-base-uncased, DistilBERT, and BERTweet, to determine the most optimal architecture for sentiment classification of these reviews. Utilizing a dataset of 30,000 preprocessed reviews sourced from Kaggle, the models were fine-tuned for a binary classification task (positive/negative). Performance was systematically evaluated using accuracy, precision, recall, and F1-Score. The experimental results reveal a highly competitive performance landscape. BERT-base-uncased achieved the highest F1-Score (0.8475), establishing it as the best choice for balanced performance. Conversely, BERTweet, pre-trained on social media text, excelled in precision (0.8619), making it superior for reliable positive predictions. Meanwhile, DistilBERT demonstrated its value by offering a compelling balance of high performance (F1-Score 0.8373) and significant computational efficiency. This research concludes that the selection of an optimal model is not absolute but is contingent on specific application requirements, such as the priority of balanced accuracy, predictive reliability, or resource efficiency.
