Abstract

The study investigates the iGen customer loyalty model that is affected by service quality, culture, loyalty program, and trust through customer satisfaction. Following the conceptual model, an inclusive set of hypotheses have been developed. The needed data were collected from 663 samples using an online survey, and Structural Equation Model with Smart Partial Least Square was applied to test the model and hypotheses. The research found that service quality, culture, loyalty programs, and trust are combined to predict customer loyalty. Trust and loyalty programs exert a more powerful impact on customer loyalty than service quality and culture variables. Customer satisfaction is a mediator between service quality, loyalty programs, customer trust, and customer loyalty. The results have some critical academic and professional implications for determining the model of consumer loyalty and the uniqueness of internet generation (iGen) in mobile communication services. The study can be used as a role model in formulating a marketing strategy management with a competitive advantage in mobile communication services in Indonesia.

Abstract

This research aims to identify and analyze thematic, methodological, and research gaps in the study of transformational leadership over the past two decades. The method used is Systematic Literature Review (SLR) with the PRISMA approach, which selects 20 articles from internationally reputable journals indexed by Scopus. Data are collected and analyzed based on research focuses, methods, and key findings related to the influence of transformational leadership on performance, innovation, organizational culture, and employee engagement. The results of the study show that transformational leadership consistently contributes positively to improving individual and organizational performance through mediation mechanisms such as trust, organizational learning, and knowledge management. However, previous research still shows limitations in contextual aspects, especially in the areas of leadership digitalization, organizational culture differences, and longitudinal research design. This study recommends that future research integrate cross-cultural and multi-method approaches to broaden understanding of transformational leadership dynamics in the digital age. Practically, the results of this research contribute to the development of leadership strategies that are adaptive, innovative, and oriented towards human resource empowerment in the context of modern organizations.

Abstract

This study aims to explain the influence of destination attributes and memorable tourism experience on revisit intention. The research employs a quantitative approach with data collected through an online questionnaire distributed via Google Form. The population is Generation Z, with samples determined using the purposive sampling technique. A total of 150 respondents who are students of Universitas Maritim Raja Ali Haji (UMRAH) were selected because they had visited Lagoi Bay at least once. The results show that most respondents experienced a clean beach atmosphere, comfortable facilities, and beautiful scenery that created a memorable travel experience. The findings indicate that destination attributes and memorable tourism experience have a positive influence on revisit intention. In other words, the better the destination’s attributes and the more memorable the tourist experience, the greater the visitors’ desire to return to Lagoi Bay.

Abstract

Pergerakan harga saham dipengaruhi oleh berbagai faktor dan bersifat fluktuatif, sehingga diperlukan metode prediksi yang mampu menangkap pola data yang kompleks. Penelitian ini bertujuan untuk memprediksi harga saham menggunakan metode Random Forest Regression. Data yang digunakan dibagi menjadi data pelatihan dan data pengujian untuk mengevaluasi kinerja model. Kinerja model dievaluasi menggunakan beberapa metrik, yaitu Mean Absolute Error (MAE), Root Mean Squared Error (RMSE), dan koefisien determinasi (R²). Hasil penelitian menunjukkan bahwa model Random Forest Regression setelah optimasi menghasilkan nilai MAE sebesar 64,02,  RMSE sebesar 84,51, dan R² sebesar 0,8484. Nilai-nilai tersebut mengindikasikan bahwa model memiliki tingkat kesalahan prediksi yang rendah dan mampu menjelaskan 84,84% variasi pada data harga saham. Berdasarkan hasil tersebut, dapat disimpulkan bahwa Random Forest memiliki kinerja yang baik dan cukup andal dalam memprediksi harga saham.   Stock price movements are influenced by various factors and exhibit high volatility, making accurate prediction a challenging task. This study aims to predict stock prices using the Random Forest Regression method. The dataset is divided into training and testing sets to evaluate the model’s performance. The performance of the model is assessed using Mean Absolute Error (MAE), Root Mean Squared Error (RMSE), and the coefficient of determination (R²). The results show that the Random Forest Regression model after optimization achieves an MAE of 64,02, an RMSE of 84,51, and an R² value of 0.8484. These results indicate a low prediction error and demonstrate that the model is able to explain 84.84% of the variance in stock price data. Therefore, it can be concluded that Random Forest is an effective and reliable method for stock price prediction.

Abstract

This study aims to analyze the community's digital literacy model and formulate strategies for utilizing social media to enhance cultural tourism promotion in the Muarajambi Temple area. The study used a descriptive qualitative approach, involving community members who manage cultural tourism activities as informants. Data were collected through in-depth interviews, observation, and documentation, then analyzed using the Miles and Huberman interactive model, which includes data reduction, data presentation, and drawing and verifying conclusions. The results show that the community's digital literacy has developed in the aspects of information retrieval, hypertextual navigation, content evaluation, and knowledge management. However, these competencies are still self-taught, resulting in social media management that has not been carried out in a planned, consistent, and sustainable manner. This condition causes digital promotion to focus more on disseminating basic information, thus failing to encourage tourists to make a decision to visit. Analysis using the AIDDA model shows that the promotional strategy implemented is still dominant at the awareness and interest stages, while the desire, decision, and action stages have not been optimized. Therefore, strengthening human resource capacity, developing a systematic content strategy, and sustainable social media management are needed to make cultural tourism promotion in the Muarajambi Temple area more effective in increasing destination attractiveness and increasing tourist visits

Abstract

This study aims to analyze the service practices of pilgrim tourists at Muarajambi Temple, a heritage-based pilgrim tourism destination. The study used a qualitative approach with a case study design to gain an in-depth understanding of the service practices applied to pilgrim tourists. Research informants were selected purposively, consisting of area managers, tourism operators, religious leaders, and pilgrim tourists. Data were collected through in-depth interviews, field observations, and documentation, then analyzed using the Miles and Huberman interactive model, which includes data reduction, data presentation, and conclusion drawing. The results show that pilgrim tourist services have accommodated the basic needs of visitors by providing physical facilities, spiritual information, and assistance in carrying out religious rituals. These service practices form three main patterns: informative services, assistance services, and facilitative services. Analysis based on the 4A concept shows that the attraction is the main strength of the area because it has high historical, cultural, and spiritual value. However, aspects of accessibility, amenities, and supporting services still require strengthening, especially in service integration, provision of facilities appropriate to pilgrims' needs, and coordination between stakeholders. These findings confirm that the development of a more structured service system is an important factor in improving the quality of the tourist experience while supporting the sustainability of cultural heritage-based religious tourism
