Abstract

As one of Indonesia’s largest marketplaces, Tokopedia provides a compelling case study to examine the profound impact of security, convenience, and consumer trust on purchasing decisions in the rapidly evolving digital commerce. However, the extent to which these factors influence purchasing decision remains a critical issue. This research is designed to analyze the impact of security, convenience, and customer trust on purchasing decision in the Tokopedia marketplace. A quantitative and descriptive framework was applied using purposive sampling, involving 102 respondents who are Tokopedia users in Surabaya city, aged 17 years and above, who have made transactions within the past year. Primary data were collected through questionnaires, while secondary data were acquired from academic references. Data processing was undertaken via Partial Least Squares-Structural Equation Modeling using SmartPLS. Model evaluation included outer model assessment for construct validity and reliability through Cronbach’s Alpha, Composite Reliability, and Average Variance Extracted (AVE), as well as inner model evaluation using R-square, Q-square, and bootstrapping tests. The results show that security, convenience, and customer trust is positive & significantly influence purchasing decision. Convenience has the most substantial effect, highlighting the importance of accessible and intuitive navigation. Customer trust is strengthened by seller integrity and transparency, while security is enhanced by cash-on-delivery (COD) systems. This study contributes to the TAM Theory (technology acceptance model) and TRA Theory (theory of reasoned action), reinforcing that security, convenience, and customer trust are crucial determinants in online purchasing decision.

The telecommunications industry is often characterized by competition between providers. Brand image and digital marketing play a crucial role in influencing consumer choices. This study aims to analyze the impact of brand image and digital marketing on purchasing decisions for IndiHome service providers in the Sidoarjo area. The research approach used was quantitative, involving the distribution of questionnaires to 97 respondents who were IndiHome users in Sidoarjo. Data processing was performed using the Structural Equation Modeling (SEM) method based on Partial Least Squares (PLS) to highlight the relationships between these variables. The research findings revealed that brand image has a positive and meaningful impact on consumers' decisions to purchase IndiHome services. The indicator with the highest loading factor was the view that IndiHome is widely recognized and considered a superior internet provider. Furthermore, digital marketing also contributed significantly to supporting purchasing decisions, with the effectiveness of product communication and promotion through digital platforms being a determining factor. The results show that brand image has a significant influence on purchasing decisions with the highest indicator loading factor of 0.845 and a mean value of 4.443 in the statement "IndiHome's brand image is widely known and trusted by the public as a provider of quality internet services".
