Abstract

This study analyzes the challenges and strategies for implementing ISO 31000: The implementation of ISO 27001 in the financial sector has been proven to improve information security and user trust. A literature review of nine journals shows that this standard is effective in managing risks, complying with regulations, and implementing security controls such as encryption and multi-factor authentication. Some institutions have reported a reduction in security incidents of up to 40%. However, implementation challenges include limited human resources and a lack of user evaluation user perception. These findings underscore the role of ISO 27001 as a critical standard for building trust in the digital age.

Abstract

This study aims to analyze the partial and simultaneous influence of social media marketing and online reviews on repurchase intention among Kopi Kenangan customers in Medan City. This research employs a quantitative approach, with data collected through questionnaires distributed using a purposive sampling technique to 106 respondents who met the specified criteria. The collected data were analyzed using multiple linear regression analysis with the aid of SPSS software. The results indicate that social media marketing has a significant positive partial effect on repurchase intention (tstatistic​ = 7.256 > ttable​ = 1.659). Similarly, online reviews also show a significant positive partial effect on repurchase intention (tstatistic​ = 4.560 > ttable​ = 1.659). Simultaneously, both independent variables have a significant effect on repurchase intention (Fstatistic​ = 26.408 > Ftable​ = 3.09). The coefficient of determination (R2) of 0.339 indicates that 33.9% of the variance in repurchase intention can be explained by social media marketing and online reviews, while the remainder is influenced by other factors. These findings confirm that digital engagement through social media and the management of online reputation are crucial strategies for fostering loyalty and repeat purchases in the modern coffee shop industry.
