Abstract

This study aims to examine the reinforcement of religious moderation through Islamic Religious Education (IRE) and its contribution to fostering students’ social harmony in SMPN 12 Gresik, a multicultural secondary school in Indonesia. Employing a qualitative descriptive approach, the study collected data through in-depth interviews, participant observation, and document analysis involving Islamic Religious Education teachers, students, and school administrators. Data were analyzed using the Miles and Huberman interactive model, encompassing data reduction, data display, and conclusion drawing. The findings reveal that the reinforcement of religious moderation is implemented through the integration of values such as tolerance, respect for diversity, social cooperation, and inclusivity within both classroom learning and the broader school culture. Islamic Religious Education teachers play a pivotal role in cultivating students’ moderate religious attitudes through dialogical pedagogical practices and social role modeling. Furthermore, students’ social harmony is strengthened through open social interactions, an inclusive school environment, and collaborative activities that transcend religious and social differences. The study concludes that Islamic Religious Education serves as a strategic instrument for promoting religious moderation and fostering social cohesion within multicultural educational settings. These findings underscore the importance of integrating inclusive religious values into educational practices to support peaceful coexistence and strengthen intercultural understanding among students.

Abstract

This study aims to analyze the implementation of Pegadaian Syariah products at the Paus Pekanbaru Branch based on field observations and interviews. The research focuses on four main products: Rahn, Gold Installments, Gold Savings, and Sharia Business Loans. A qualitative descriptive method was applied using observation, interviews, and documentation as data collection techniques. The findings show that Rahn is the most widely used product because it offers a fast disbursement process, simple procedures, and relatively accessible requirements for customers who need short-term financing. Gold Installments and Gold Savings provide alternative sharia-compliant investment instruments based on real assets, allowing customers to own gold gradually and safely. Meanwhile, Sharia Business Loans play an important role in supporting micro-enterprise development by providing financing that follows Islamic principles. Overall, the implementation of these products reflects Pegadaian Syariah’s contribution to expanding financial inclusion, strengthening public understanding of sharia-based financial services, and providing practical solutions for community economic needs. However, product socialization and customer literacy still need improvement to optimize utilization. This improvement is expected to enhance product acceptance and strengthen sustainable sharia financial service performance.
