Purpose: This study aims to evaluate and prioritize sustainability reporting standards in the banking sector by identifying key criteria influencing their selection, with a particular focus on integrating local regulatory compliance and global best practices. Research Methodology: The research employs a mixed-methods approach, beginning with qualitative interviews with key stakeholders and a literature review to identify relevant criteria. Insights from this phase inform the quantitative analysis using the Analytic Hierarchy Process (AHP). Five sustainability reporting experts from ABC Bank served as respondents, assessing alternative standards based on predetermined criteria derived from both interviews and literature studies. Results: The findings indicate that “integration with financial metrics” and “use of technology” are the most critical criteria in selecting sustainability reporting standards. AHP analysis shows that while POJK 51 meets regulatory requirements, global frameworks such as GRI and SASB offer broader and more investor-oriented disclosures. Combining multiple standards provides a more comprehensive approach, though it demands greater resources and capacity. Conclusion: The study concludes that hybrid adoption of local and global sustainability frameworks enhances reporting credibility, aligns with stakeholder expectations, and strengthens competitive positioning Limitations: The small sample size of five experts from a single bank limits the generalizability of findings. Contribution: This research provides empirical insights into the prioritization of sustainability reporting standards, offering practical guidance for banks and policymakers seeking to enhance ESG transparency and alignment with both domestic regulations and international standards.

Purpose: This study examines the effectiveness of Social Media Marketing Activities (SMMA) in enhancing brand loyalty at PT. Mumpuni Inti Mandiri.

Data were gathered through online surveys targeting PT customers in Jakarta. Mumpuni Inti Mandiri. Structural equation Modelling (SEM) using Partial Least Squares (PLS) via SmartPLS 3.2.6 was employed to analyze the data. Validity and reliability tests ensured the instruments’ accuracy. The hypotheses were tested using one-tailed t-statistics. Results: The results show that customer perceptions of SMMA, self-brand connection, brand equity, brand trust, and brand loyalty were high. SMMA significantly influences self-brand connection, brand equity, and brand trust. Moreover, brand loyalty is directly and indirectly affected by these mediators. This implies that PT.

Conclusions: The SMMA plays a vital role in building brand loyalty by enhancing brand-related psychological factors. Integrated social media marketing efforts have proven valuable in creating strong brand-consumer relationships. Limitations: The study’s scope was limited to one company and used self-reported survey data, which may have affected generalizability. Contribution and Novelty: This study introduces an integrated model that connects SMMA with brand loyalty through emotional and cognitive pathways, offering insights into effective digital branding strategies for emerging markets.
