Abstract

An effective educational marketing strategy requires accurate school segmentation to enhance new student recruitment. Traditional segmentation methods such as K-means are often used, but they have limitations in capturing the flexibility of school characteristics. Fuzzy C-Means (FCM) offers a more adaptive approach by allowing each school to simultaneously have a degree of membership in several clusters. However, the performance of FCM highly depends on determining parameters such as the number of clusters (k) and the level of fuzziness (m), which are not always optimal when determined manually. This study develops a new framework for dynamic educational marketing segmentation in student recruitment by optimizing FCM using three metaheuristic techniques: Genetic Algorithm (GA), Particle Swarm Optimization (PSO), and Differential Evolution (DE). Performance was evaluated using the Fuzzy Silhouette Index (FSI). The experimental results showed that DE yielded the best results with the highest FSI value (0.8023), producing eight main clusters based on the Recency, Frequency, and Monetary (RFM) model. Based on the clustering results, a personalized and adaptive marketing strategy was designed to enhance the effectiveness of student recruitment. The proposed framework enhances segmentation accuracy and supports the implementation of dynamic data-driven marketing in the context of higher education. This study also opens new directions for educational data mining research and machine-learning-based marketing strategies.

Abstract

The increasing demand for efficient and usercentered public services has led to the development of the J-KOPI (Jember Smart City) application. However, user satisfaction remains a challenge due to varying levels of perceived service quality and public trust. This study aims to analyze the impact of service quality on user satisfaction, with perceived usefulness as a mediating variable. Utilizing a descriptive quantitative approach, the study employs Structural Equation Modeling (SEM) to assess relationships between these variables. Data were gathered through observations, online questionnaires, and documentation, focusing on key indicators such as reliability, responsiveness, assurance, empathy, and trust dimensions. The results reveal that both service quality significantly influence user satisfaction directly and through perceived usefulness. Notably, service quality dimensions positively correlate with perceived usefulness, enhancing users' productivity and satisfaction. These findings suggest that strengthening both service quality is essential for improving user satisfaction and promoting broader adoption of J-KOPI, supporting Jember's smart city vision.

Abstract

Papua’s Special Autonomy Fund represents one of the most ambitious asymmetric decentralization initiatives in Southeast Asia. Yet, over 20 years later, the region remains among Indonesia’s most underdeveloped. This paper investigates the governance failures underlying this paradox, including regulatory overlap, elite capture, and weak local fiscal capacity. It reviews recent evaluation studies and government reports to assess how decentralization design flaws and implementation gaps have constrained service delivery. The analysis offers policy recommendations to restructure the autonomy framework toward greater accountability, data-driven planning, and inclusive development.

Abstract

The increasing use of influencers in digital marketing strategies encourages the importance of understanding the factors that shape satisfaction with influencers and their impact on consumer purchase intentions. This study aims to analyze the effect of attractiveness, trustworthiness, expertise, electronic word of mouth (E-WOM), brand trust, and brand image on purchase intention, with influencer satisfaction as a mediating variable. This research method uses a quantitative approach with data collection techniques through a questionnaire survey to 200 Bobby Saputra followers with a convenience sampling technique. Data analysis was carried out using Structural Equation Modeling (SEM) based on Partial Least Squares (PLS). The results showed that attractiveness, expertise, brand trust, and brand image have a positive effect on influencer satisfaction, where visual appeal, expertise, and perception and trust in the brand are key factors in shaping satisfaction with influencers. Conversely, trustworthiness and E-WOM did not show a significant effect on influencer satisfaction, indicating that personal trust and digital communication are not enough to create satisfaction directly. In relation to purchase intention, it was found that attractiveness, E-WOM, brand trust, brand image, and influencer satisfaction have a positive and significant effect, which confirms the importance of visual aspects, brand reputation, and positive experiences with influencers in driving purchase intention. Meanwhile, trustworthiness and expertise do not have a significant effect on purchase intention, indicating that emotional considerations and brand perceptions are more dominant than personal credibility or technical competence.

Abstract

The increasing competition in higher education has prompted Muhammadiyah University of Jember to introduce the new program innovation, Recognisi Pembelajaran Lampau (RPL). To ensure the sustainability and growth of the program and contribute positively to society, understanding student loyalty is crucial for educational institutions. The purpose of this study is to examine the impact of brand image, service quality, and brand trust on student loyalty, with satisfaction serving as an intervening variable. This study method used is a quantitative survey with data collected through questionnaires. The respondents in this study were 144 students of the RPL program at Universitas Muhammadiyah Jember. Data analysis was performed using Structural Equation Modeling (SEM) with WarpPLS 8.0 software to test the relationships between the variables studied. The results show that brand image, service quality, and brand trust have a positive and significant influence on student satisfaction. Additionally, student satisfaction has a significant influence on student loyalty. Although brand image and service quality do not have a direct influence on loyalty, satisfaction as an intervening variable plays an important role in mediating the relationship between brand image, service quality, and brand trust with student loyalty. These findings provide practical implications for educational institution managers to improve brand image, service quality, and brand trust in order to enhance student satisfaction. By improving these three aspects, it is expected that students will be more loyal and have a higher commitment to their educational institution through mediated satisfaction. Through student loyalty, the marketing of educational programs can also be more efficient and effective for prospective new students.

Abstract

Netflix is a subscription-based video streaming platform that offers a selection of films and documentaries each month. During the COVID-19 pandemic, streaming services experienced significant growth. This study examines the influence of Netflix media usage motivation on viewer satisfaction in East Java. It applies Guo and Chan-Olmsted’s Video Streaming Platform Representation Theory, McQuail’s Media Usage Motivation Theory, Blumer and Katz’s Uses and Gratification Theory, McMillan’s Interactivity Perception Theory, and Satisfaction Theory. Using a quantitative explanatory method, data were collected through an online questionnaire from 190 respondents and analysed using SPSS 26 and AMOS 22 with Structural Equation Modelling (SEM). The results indicate that Video Streaming Platform Representation, Media Usage Motivation, and Perception of Interactivity significantly influence viewer satisfaction, both simultaneously and partially. Media usage motivation—covering information seeking, personal identity, social integration, and entertainment—shows the most substantial effect. Viewers are satisfied because Netflix provides engaging information about new films and opportunities for interaction among users. The novelty of this study lies in distinguishing new media like Netflix from mainstream media, emphasising how streaming platforms enable users to access entertainment and exchange film- related information within online communities.

Abstract

This study investigates the determinants influencing participation in gastronomic tourism in Samarkand, Uzbekistan, focusing on the role of distance, price satisfaction, and demographic characteristics. Using data collected from 303 respondents, logistic regression and decision tree analyses were applied to assess key behavioral predictors of culinary travel. The results reveal that distance is the most significant factor influencing willingness to engage in gastronomic tourism—individuals willing to travel farther are substantially more likely to seek authentic food experiences. In contrast, satisfaction with food prices and demographic factors such as age, gender, and expenditure levels were found to be statistically insignificant. These findings highlight that logistical accessibility outweighs demographic variables in shaping tourism participation. The study contributes to the literature by providing empirical evidence from an emerging destination, emphasizing the importance of mobility and access in gastronomic decision-making. Practical implications include the need for policymakers to improve transportation infrastructure, enhance culinary destination visibility, and promote authentic local food experiences. By strengthening these elements, Uzbekistan can better position itself as a prominent culinary tourism destination in Central Asia. The research also opens opportunities for future studies to explore psychological, cultural, and digital factors influencing food tourism behavior.
