Abstract

This study aims to examine the influence of perceived risk and credibility on purchase intention toward concert ticket “war” services, with trust serving as a mediating variable. This research employs a quantitative approach, with data collected through an online questionnaire distributed via Google Form to members of the “SEVENTEEN NEW_ IN JAKARTA SOON” community on the X (Twitter) platform. The community is known for actively sharing concert information, ticketing strategies, and peer-to-peer ticket transactions, making it relevant for representing consumer behavior toward concert ticket third-party services. The sample was determined using a purposive sampling technique based on specific criteria, involving 105 respondents with a total of 13 indicators covering 4 perceived risk indicators, 4 credibility indicators, 5 trust indicators, and 4 purchase intention indicators. The research instrument used a 5-point Likert scale to measure respondents’ perceptions of each variable indicator. Data were analyzed using the Structural Equation Modeling-Partial Least Squares (SEM-PLS) method, with mediation testing conducted through bootstrapping techniques. The results indicate that credibility has a positive and significant effect on trust and purchase intention, and trust also has a positive and significant effect on purchase intention. Furthermore, trust partially mediates the relationship between credibility and purchase intention. In contrast, perceived risk does not have a significant effect on trust or purchase intention, nor does it have an indirect effect on purchase intention through trust. These findings suggest that in the context of K-Pop concert ticket “war” services in Indonesia, credibility and trust play a more dominant role in shaping purchase intention than perceived risk.

Abstract

The rapid development of communication technology and the high level of social media usage in Indonesia have intensified competition among instant messaging applications in retaining users. Although LINE was once one of the most popular applications, in recent years there has been a decline in the number of active users, which is believed to be influenced by the removal of several key features, a decrease in perceived usefulness, and various complaints related to system quality. The condition raises questions regarding the factors that influence users’ intentions to continue using the LINE application on an ongoing basis. This study aims to analyze the effect of System Quality and Perceived Usefulness on the Continuance Intention of the LINE application, with Satisfaction acting as a mediating variable. A quantitative approach was employed through an online survey involving 200 respondents in Jakarta who had used LINE for at least the past year. The data were analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS). The results indicate that system quality and perceived usefulness have a positive and significant effect on satisfaction. Furthermore, perceived usefulness and satisfaction have a positive and significant effect on continuance intention. However, system quality is proven to have no significant effect on continuance intention. The indirect effect findings indicate that satisfaction significantly mediates the relationship between system quality and perceived usefulness on continuance intention.

Abstract

This research aims to analyze the influence of perceived usefulness, perceived ease of use, and social influence on the continuance intention of the LinkAja application, both partially and simultaneously. This study employs a quantitative approach with a survey method and Structural Equation Modeling based on Partial Least Squares (SEM-PLS) as the analysis technique. The sample in this research consists of 255 respondents residing in the DKI Jakarta area , selected through a purposive sampling technique. Data were analyzed using SmartPLS 4.0 software. The results of the analysis indicate that: (1) Perceived usefulness has a positive and significant effect on the continuance intention of the LinkAja application. (2) Perceived ease of use has a positive and significant effect on the continuance intention of the LinkAja application. (3) Social influence has a positive and significant effect on the continuance intention of the LinkAja application. These findings confirm that social influence is the most dominant factor in influencing user continuance intention. Therefore, application developers need to integrate the usefulness of features, an intuitive interface, and the strengthening of the community base to maintain user loyalty in the competitive digital wallet market.

Abstract

This study aims to design the UI/UX and develop a high-fidelity prototype of a web-based healthy food catering ordering platform named NutriGo using a Human-Centered Design approach. The research is grounded in systemic problems faced by consumers, including the absence of transparent menu and price information, reliance on manual communication, and order discrepancies due to the lack of a standardized order management system. This study applies the Waterfall method integrated with five stages of Design Thinking: Empathize, Define, Ideate, Prototype, and Test. The unit of analysis is prospective users of application-based healthy food catering services, using convenience sampling for 30 usability testing respondents and purposive sampling for 5 interview respondents. Data were collected through questionnaires, prototype testing scenarios, the System Usability Scale (SUS), and semi-structured interviews, then analyzed using SUS scoring based on Brooke (1996) and thematic analysis. The results show that the NutriGo prototype obtained an average SUS score of 81.33, which falls into the Excellent category and exceeds the minimum acceptance threshold, while all respondents expressed positive intentions on the three Behavioral Intention indicators: Intention to Use, Continuance Intention, and Recommendation Intention.
