This study examines the impact of customer relationship management (CRM) practices and social media marketing (SMM) activities on customer retention among MSMEs in Aceh. It considers the dual role of social media in relationship management (CRM) and business engagement (SMM). Recognizing the widespread use of social media, the study explores different stages of its adoption and utilization in business. A formalized social media business profile is used as the moderating variable, defined by a firm's formal allocation of responsibility, outsourcing, funding, governance of social media, and broader changes to structure, processes, leadership, training, and culture. Data was collected from 565 MSMEs using questionnaires and analyzed with partial least squares structural equation modeling (PLS-SEM) and multi-group analysis. The results demonstrated a high predictive power of the model on customer retention. Within CRM, the findings indicated a significant difference in the effect of key customer focus on customer retention, with higher effects observed in MSMEs that do not formalize their social media business profiles. Additionally, technology-based CRM showed significantly higher effects on customer retention for those who formalize their social media profiles. Within SMM, the study revealed significant differences in the effects of customization and trendiness on customer retention, both of which were more pronounced in MSMEs without formalized social media profiles. Furthermore, word-of-mouth had a significantly higher impact on customer retention for MSMEs with formalized social media profiles. This research contributes theoretically by developing an integrated framework that identifies how key customer focus, CRM organization, knowledge management, technology-based CRM, customization, entertainment, interaction, trendiness, and word-of-mouth influence customer retention. It also explores the moderating effects of formalized social media business profiles on CRM practices and SMM activities within MSMEs.

The purpose of this study was to determine the effect of supply chain integration capabilities on operational performance by mediating green supply chain management in manufacturing companies. This research method is quantitative and the sampling method in this study uses probability sampling. The primary data is obtained by distributing 490 online questionnaires to manufacturing companies. Validity and reliability testing were carried out using Structural Equation Modeling Partial Least Square (SEM-PLS) and data processing was accomplished using SmartPLS. The findings in this study found that supply chain integration capabilities had a direct positive and significant effect on operational performance while supply chain integration capabilities had a positive and significant effect on green supply chain management. In addition, green supply chain management had a direct positive and significant effect on operational performance. The ability of supply chain integration also maintained a positive and significant effect on operational performance mediated by green supply chain management.

Word-of-mouth (WOM) has been recognized as one of the most influential forms of information transmission. Advances in information technology and the emergence of online social networking sites have changed the manner in which data is delivered. This phenomenon has an impact on consumers because readily accessible information can significantly influence consumption-related decisions. The purpose of this paper is to examine the role of e-WOM in mediating the influence of the marketing mix and destination image on the intention of tourists to re-visit destinations. The primary data was derived from 190 tourist respondents and collected by means of questionnaires distributed via Google forms. The resulting data was analyzed using AMOS-SEM, while evaluating the role of e-WOM as a model involving a Sobel test. The results of the analysis indicated that e-WOM plays a highly significant role in piquing individual's' interest in re-visiting tourist sites. Contributory factors such as the marketing mix, destination image, and e-WOM all support this research hypothesis.

Today, Coronavirus is a pandemic that has spread worldwide and causes many problems, including socio economic problems in society. Therefore, e-marketing has an essential function in acquiring new customers, generating leads, and generating revenue for your business by reaching customers interested in your products and services. A digital platform such as web marketing is online marketing to prospective leads and high-value consumers. Thus, the present study examined the usage of e-marketing as a model for buying decisions moderated by perceived risk during the covid-19 pandemic in Aceh Province, Indonesia. This quantitative study involved 325 respondents and was collected through a survey by filling out the questionnaires. Also, e-marketing is measured by perceived usefulness, perceived ease of use as exogenous variables. Therefore, perceived risk is a mediating variable, and the consumer buying decision is an endogenous variable. The data were analyzed using Structural Equation Modelling – Analysis of Moments Structure (SEM-AMOS). The results showed that e-marketing (perceived usefulness and ease of use) positively and significantly affects consumer buying decisions. This study also applied the Sobel test and indicated that perceived risk mediates perceived usefulness and ease toward consumer buying decisions. In conclusion, this study has successfully examined the relationship between e-marketing via perceived usefulness and perceived ease of use. Also, it proves that perceived risk plays a mediating role (partial mediator) in the relationship of perceived usefulness and ease of use on consumer buying decisions. This tested model has become a formulation, especially in marketing science, where it turns out that during the covid-19 pandemic, the buying decision model in the marketplace is a function of the perceived usefulness and perceived ease of use of consumers towards the marketplace, as well as the perceived risk of the marketplace as a partial mediator. So that marketplace manufacturers can drive consumer buying decisions by consumers by creating a strengthening of perceived usefulness and perceived ease of use for consumers, thereby affecting consumers' perceived risk and impacting their buying decisions.
