Customer satisfaction and loyalty are central issues in marketing management, as both play crucial roles in ensuring business sustainability amid increasing competition. Satisfied customers tend to make repeat purchases, provide positive recommendations, and build long-term relationships with the company. Therefore, understanding the factors that influence customer satisfaction and loyalty has become an important agenda for both academics and practitioners. This study aims to address two main questions: (1) What factors influence customer satisfaction? and (2) How does satisfaction contribute to the formation of customer loyalty? The method used is a literature review, selecting articles from various online databases such as ResearchGate, Academia, and open-access journals using the keywords customer satisfaction and customer loyalty. Of the 45 identified articles, 20 were selected for in-depth analysis. The review results reveal three main trends: first, service and product quality are the most consistent determinants of satisfaction; second, price, promotion, and brand image play significant roles; and third, customer trust is an essential variable that strengthens the satisfaction–loyalty relationship. Overall, satisfaction functions as the main mediating variable in the formation of customer loyalty.

This study aims to uncover public perception of Islamic banking in Jember Regency as well as the factors that cause low account ownership in Islamic banks, even though the majority of the population is Sunni Muslim. This study uses a descriptive qualitative approach with data collection techniques through direct interviews with people who do not choose Islamic banks as financial institutions. The results of the study show that the low level of public knowledge about Islamic banking systems and products is the main factor influencing their decisions. In addition, promotions carried out by Islamic banks are considered less effective and do not directly touch the needs and understanding of the community. The lack of supporting facilities such as ATMs and service offices also strengthens the perception that Islamic banks are not significantly different from conventional banks. Weak branding and education cause Islamic banking products to be less attractive in the eyes of the public. Therefore, a more intensive education strategy and a promotional approach that directly touches the community, as well as an improvement of basic service facilities so that Islamic banks can provide optimal services and increase public trust. This study recommends strengthening Islamic financial literacy and expanding access to services as strategic steps to encourage Islamic financial inclusion in Jember.

This study aims to analyze the perceptions of teachers at Pondok Pesantren Assalafiyah Nurul Hidayah Pangkalpinang regarding Islamic banking. Despite the religious background of the teachers, the findings reveal that the majority still use conventional banks due to limited knowledge about Islamic banking principles, lack of socialization, and practical reasons such as convenience and proximity. The research uses a qualitative descriptive method involving 21 teachers through in-depth interviews, observations, and documentation. The results indicate that while the teachers have a generally positive view of Islamic banking, their understanding remains partial, particularly regarding profit-sharing mechanisms, riba prohibition, and Islamic financial products. Moreover, their interest in saving at Islamic banks is potential but requires further education and socialization to encourage real participation. This research highlights the need for more proactive promotion and financial literacy programs from Islamic banking institutions to increase public awareness, especially among religious educators, regarding the use of sharia-compliant financial services.

Tuberculosis (TB) is an infectious disease caused by the bacterium Mycobacterium tuberculosis. It is transmitted through the air, specifically through droplets expelled by sufferers when coughing or sneezing. TB is divided into two main types: pulmonary TB, which attacks the lungs, and extrapulmonary TB, which can affect other organs such as the pleura, lymph nodes, skin, bones, and meninges. In the Community Health Center (Puskesmas) work area, 77 new cases of pulmonary TB were recorded from January to April 2025. Meanwhile, coverage of Tuberculosis Prevention Therapy (TPT) only reached 44.7%, still below the national target of at least 50%. This condition indicates the need for increased health promotion activities and community diagnostic approaches as promotive and preventive measures, in order to increase TPT coverage and reduce the incidence of TB. The results of the respondent questionnaire showed that the level of public knowledge about TB reached 64.6%, positive attitudes at 94%, and preventive behavior at 72%. Based on these findings, it is recommended that outreach activities be conducted regularly to improve public understanding, which can ultimately encourage behavioral changes and reduce TB cases.

This study aims to thoroughly examine the influence of menu variety, taste, and price on customers' purchasing decisions at CEZ-ROS Restaurant, located in Kediri Regency. Understanding these factors is crucial for the restaurant to enhance customer satisfaction and improve sales performance. The research employs a quantitative approach with an associative research type, designed to explore relationships between variables.

The results indicate that menu variety, taste, and price significantly impact purchasing decisions both individually and together. Specifically, customers prefer restaurants offering a diverse menu, delicious food, and reasonable pricing. The F-test confirms the strong combined effect of these factors on consumer behavior. However, the coefficient of determination also suggests that while these variables are important, other external influences such as service quality, ambiance, and promotions may also affect purchasing decisions. Overall, this study highlights that CEZ-ROS Restaurant should focus on maintaining menu diversity, enhancing taste quality, and setting competitive prices to attract and retain customers effectively.
