Currently, streaming applications have been widely used by users to get comfort and pleasure in life. Users communicate with each other on social media related to the activities carried out. Communication is formed online as electronic word of mouth (e-WOM) between one user to another. The data distributed was 1238 respondents using streaming applications and 324 respondents in Indonesia who had used e-wallet payments as members. The analysis data was to answer all research hypotheses using partial least squares. The data processing results show that e-WOM impacts the perceived ease of use of e-wallets by 0.408. E-WOM positively impacts the perceived usefulness of the e-wallet by 0.270. E-WOM has an impact on e-wallet payment intention of 0.190. Perceived ease of use has an effect of 0.175 and perceived usefulness of 0.259 on e-wallet payment intention. Perceived ease of use influences perceived usefulness of 0.395. Perceived ease of use and perceived usefulness impact customer satisfaction in terms of 0.157 and 0.217. Finally, it was found that e-wallet payment intention has an impact of 0.173 on customer satisfaction. The results of this study contribute to e-wallet payment users and managers building two-way and effective communication through social media so that they can quickly and accurately solve user problems. The theoretical contribution is to enrich the theory of marketing behavior and technology acceptance models in electronic commerce.

Business competition is increasingly complex, and there are no clear boundaries between products, so company operational processes are needed efficiently and effectively. The performance achieved is obtained through the implementation of an integrated information technology known as ERP. ERP implementation requires a person in charge of a business function called a key user who understands business processes and collaborates with ERP system vendors. The study obtained data that can further process from 77 manufacturing companies in East Java by purchasing an ERP or self-development package. Data processing uses PLS to answer all research hypotheses. The results show that key user capability was able to have a direct effect on the effective design of business processes of 0.643 and integration data management of 0.373. In contrast, it had no direct impact on ERP suitability. Effective Design of Business Processes has an immediate effect on Integration Data Management of 0.338 and ERP suitability of 0.395. The results also show that Integration Data Management has a direct effect on ERP suitability of 0.462. The data processing results for the indirect effect showed that key user capability influenced ERP suitability through the effective design of business processes of 0.507. Key user capability affects ERP suitability through Integration Data Management, and it is obtained as much as 0.254. The last hypothesis, key user capability, influences ERP suitability through effective Design of Business Processes and Integration Data Management of 0.182. The study results provide theoretical contributions to ERP implementation success factors, while practical gifts give key users a good understanding of the company's business processes and ERP systems.
