Abstract

Examining consumer evaluations of food on social media provides relevant in- formation for anyone searching, especially immigrants and tourists. This infor- mation is also highly valuable for food stall owners and restaurant managers be- cause it helps them improve the quality of the food they serve based on customer feedback. However, sentiment analysis of food reviews often faces challenges due to inadequate data preprocessing, which leads to low classification accuracy. This study aims to improve sentiment recognition accuracy in food reviews by optimizing the feature attribute selection process in the classification model. The classification model employed in this research is Naive Bayes (NB), enhanced through a hybrid feature selection approach that combines the information gain (IG) algorithm and the genetic algorithm (GA). This combination is designed to maximize the selection of the most relevant feature attributes, thereby improving the model’s ability to identify positive, negative, and neutral sentiments in con- sumer food reviews on social media. The experimental results show that the hybrid IG-GA model achieved the highest accuracy rate of 93%, outperform- ing models that use individual algorithms. These findings demonstrate that the hybrid feature selection method effectively enhances the sentiment analysis performance of the Naive Bayes model. This study contributes to the develop- ment of food recommendation systems, the improvement of service strategies for culinary businesses, and supports the achievement of SDG 8 (Decent Work and Economic Growth) and SDG 9 (Industry, Innovation, and Infrastructure).

Abstract

This study explores the impact of educational information systems on enhancing learning accessibility in higher education, as digital tools increasingly become integral to academic support, and student engagement. The main objective is to assess how these systems improve access to learning resources and facilitate communication, particularly for students from diverse backgrounds and with varying educational needs. Using a mixed-methods approach, this research combines quantitative analysis of accessibility metrics with qualitative insights from surveys and interviews with students and faculty across different higher education institutions. The findings show that educational information systems significantly enhance learning accessibility by providing flexible access to resources, facilitating real-time feedback, and supporting personalized learning paths. These systems also improve student engagement by enabling convenient access to materials and fostering a collaborative learning environment that accommodates different learning styles. However, the study identifies several barriers, including gaps in digital literacy, usability challenges, and unequal access to the necessary infrastructure, which can limit the effectiveness of these systems in reaching all students equally. Additionally, concerns around data privacy and system complexity are noted as areas needing attention to build user trust and ensure smoother system integration. The study concludes that while educational information systems hold great promise for improving accessibility and inclusivity in higher education, addressing these barriers through targeted training, digital equity initiatives, and robust data protection policies is essential for maximizing their potential. These insights offer valuable guidance for educational institutions aiming to create more inclusive learning environments through strategic integration of educational information systems.

Abstract

In the fashion industry, particularly within the anime clothing brand sector, building consumer loyalty has become a crucial challenge for ensuring long- term growth while supporting sustainability principles aligned with the Sustainable Development Goals (SDGs), specifically SDGs 8 and SDGs 12. This study aims to analyze various digital marketing approaches that can enhance consumer loyalty toward anime clothing brands by examining how digital interactions, visual identity, and community engagement contribute to sustained brand consumer relationships. The research employs a descriptive qualitative approach supported by observational data from social media analytics, documentation of digital campaign activities, and the interpretation of consumer engagement patterns across multiple digital platforms. The findings indicate that digital strategies such as leveraging social media to strengthen brand presence, collaborating with anime influencers, utilizing community based content, and implementing personalization through email marketing and loyalty programs effectively increase consumer emotional attachment and behavioral loyalty. Brands that successfully create emotionally engaging digital experiences and interact authentically with their audiences demonstrate a stronger potential to build sustainable loyalty. Furthermore, maintaining consistent brand com- munication, ensuring continuity in marketing campaigns, and integrating SDGs oriented values are identified as essential components for sustaining long-term relationships with consumers. The study concludes that digital marketing not only strengthens brand visibility but also plays a strategic role in shaping responsible consumer behavior, fostering loyalty within niche fashion communities, and supporting broader sustainability goals in the anime fashion industry.

Abstract

In the era of digital transformation, Higher Education Institutions (HEIs) face increasing pressure to modernize their service delivery to meet evolving student expectations. While Omnichannel Integration (OCI) has revolutionized customer experiences in retail and banking, its application within the educational sector remains underexplored. This systematic literature review aims to bridge this gap by examining the impact of OCI on Student Engagement and Word-of-Mouth (WoM). Adhering to the PRISMA guidelines, a rigorous screening process was conducted across multiple academic databases, resulting in the analysis of 74 eligible studies published between 2014 and 2024. The thematic analysis identifies four core dimensions of OCI Channel Service Configuration, Content Consistency, Quality Assurance, and Process Consistency. The findings reveal a significant distinction between commercial and educational contexts in HEIs, the integration of physical and digital touchpoints is not merely a logistical upgrade but a strategic necessity for relationship building. Crucially, the review establishes that OCI does not automatically generate advocacy. Instead, the student engagement acts as a vital mediating variable, meaning that seamless integration fosters deeper engagement, which subsequently drives positive WoM. This study contributes to the literature by synthesizing fragmented evidence into a cohesive framework, offering university administrators practical strategies to enhance student retention and institutional reputation through consistent cross channel experiences.

Abstract

The increasing reliance on cloud computing technologies has driven digital business transformation across various industries, offering scalability, flexibility, and cost efficiency. However, this rapid adoption has simultaneously introduced complex cybersecurity challenges, including data breaches, unauthorized access, and system vulnerabilities that threaten operational continuity and trust. In response to these growing concerns, this study aims to analyze and develop effective cloud based cybersecurity strategies that enhance the resilience of digital business operations during transformation processes. The objective of this research is to identify and evaluate strategic cybersecurity practices that can strengthen cloud infrastructure during digital change. Employing a mixed method approach, the research combines an extensive literature review with qualitative expert interviews involving IT professionals and cybersecurity practitioners from cloud reliant enterprises. A total of 126 participants were involved in the data collection phase, comprising 98 valid survey respondents and 28 interview informants. The results reveal that while many organizations have implemented basic cloud security protocols, only a few have adopted comprehensive, adaptive frameworks capable of withstanding evolving cyber threats. Key strategic elements identified include the integration of zero trust architecture, continuous risk assessment, multi factor authentication, cloud native security tools, and regular employee training. Furthermore, organizations that embedded cybersecurity planning into their digital transformation roadmap demonstrated higher resilience, faster recovery from incidents, and stronger regulatory compliance. Based on these findings, the conclusion emphasizes that a proactive, strategy driven approach to cloud cybersecurity not only mitigates risks but also strengthens the long term sustainability of digital transformation efforts. The proposed framework serves as a guide for decision makers seeking to secure their cloud infrastructure while maintaining agility and innovation in an increasingly digital and threat prone business environment.
