Abstract

In an era of globalization, companies must optimize their resources to meet customer needs. To improve the quality of human resources, companies must focus on areas such as the work environment, management support, organizational culture, employee engagement, and employee satisfaction. The study aims to identify the employee's performance in relation to its association with the variable studied and analyze it based on the supporting component. Data collection occurs through surveys and questionnaires, while analysis methods include Structural Equation Modeling (SEM). The results showed that a significant relationship between employee performance and employee characteristics on the work environment variable of 0.473 and employer engagement of 0.440 has been demonstrated. Employees who work in a positive and supportive work environment and feel engaged in their work tend to be more committed, more productive and qualified, more satisfied and motivated, and have a positive work culture. These aspects have the ability to increase employee satisfaction and employee performance, which in turn contribute to the overall success of the company.

Abstract

The rapid growth of social commerce through TikTok Shop has opened new opportunities for businesses and consumers in Indonesia, including in the city of Ambon. This study aims to analyze the factors influencing consumers’ behavioral intention and use behavior in shopping on TikTok Shop by applying the Unified Theory of Acceptance and Use of Technology 2 (UTAUT 2) model. The respondents of this research were TikTok Shop users in Ambon who had made at least one transaction, with a minimum sample size of 200 participants. The results show that all UTAUT 2 constructs, except for facilitating conditions on use behavior, have a significant effect on consumers’ intention and usage behavior. The variable behavioral intention was found to be the most dominant factor driving actual usage behavior, with R² values of 0.753 for behavioral intention and 0.817 for use behavior, indicating a strong predictive capability of the model. These findings affirm the relevance of the UTAUT 2 model in explaining technology adoption in the context of social commerce and provide practical implications for platform developers and digital business practitioners to design marketing strategies that align with the characteristics of consumers in eastern Indonesia.

Abstract

This study is motivated by the presence of dependence between event times in bivariate survival data, which cannot be adequately captured by univariate Cox models. A copula-based bivariate survival model with Cox Proportional Hazards marginals is considered. The estimation procedure follows a two-stage approach, where marginal parameters are first obtained using partial likelihood and the baseline survival function is estimated via the Breslow method. In contrast to conventional approaches that treat marginal estimates as final or imposing shared parameter structures, this study introduces a modification in the second stage by performing simultaneous joint estimation of marginal without imposing shared parameter and dependence parameters using the BHHH algorithm. This allows the marginal parameters to be estimated while explicitly accounting for the dependence between event times. The evaluation was conducted via simulation with variation in sample size, censoring, dependency level and copula types. Simulation results show that the proposed method produces stable and reliable parameter estimates while preserving the interpretability of marginal effects, providing a flexible framework for modeling dependent bivariate survival data.

Abstract

The esports industry has experienced significant growth in recent years, attracting the attention of various sponsors to utilize these platforms in achieving their business goals. This study aims to analyze the effectiveness of esports sponsorship in the Mobile Legends Professional League (MPL) on brand associations and consumer purchase intentions. Using a quantitative approach and Structural Equation Modeling (SEM) techniques through SmartPLS, data was collected from 160 respondents who are active in the esports community in Indonesia. The results showed that positive attitudes towards sponsors (?=0.461, p<0.001) and sincerity of sponsorship motives (?=0.177, p=0.039) had a significant effect on brand association. Sponsor-event suitability (?=0.241, p=0.030) and activity engagement (?=0.240, p=0.004) were also shown to strengthen brand associations. For purchase intent, attitudes towards sponsors (?=0.391, p<0.001), sincerity of motives (?=0.223, p=0.013), and activity involvement (?=0.197, p=0.037) showed significant influences. This research model was able to explain 88.3% of brand association variance and 85% of purchase intention variance. These findings provide strategic insights for esports sponsors to optimize their investments through an authentic and relevant approach to the target audience.

Abstract

The rapid growth of short-video–based social media, particularly TikTok, has transformed the way companies engage with consumers and stimulate purchase intention, especially among Generation Z as digital natives. However, for local brands such as Eiger in the travel and outdoor equipment industry, a key challenge remains in converting digital marketing activities into actual purchase intention, as reflected in the gap between high offline conversion rates and relatively low online sales contributions. This research aims to analyze the effects of content marketing and influencer marketing on purchase intention for Eiger’s travel products among Generation Z using a quantitative approach through a survey of 300 respondents who have been exposed to Eiger’s TikTok content. The research model is analyzed using the Stimulus–Organism–Response (S-O-R) framework and tested with Partial Least Squares–Structural Equation Modeling (PLS-SEM) employing SmartPLS software. The findings indicate that both content marketing and influencer marketing significantly enhance perceived enjoyment, which in turn serves as a strong mediator in increasing purchase intention. Furthermore, gender moderates the relationship between content marketing and perceived enjoyment, with female consumers showing greater responsiveness to storytelling and aesthetically appealing content, while male consumers respond more strongly to informative content. In contrast, gender does not moderate the relationship between influencer marketing and perceived enjoyment, suggesting a relatively homogeneous perception of influencers among Generation Z consumers. This study contributes to the literature by extending the application of the S-O-R theory to short-video marketing contexts and enriching empirical insights into Generation Z consumer behavior in Indonesia.
