Abstract

This study aims to analyze the influence of financial ratios on the stock price of KBMI 3 banks in Indonesia for the period 2017–2024. The variables used include: Return on Equity (ROE), Capital Adequacy Ratio (CAR), Price to Book Value (PBV), and Non-Performing Loan (NPL), with a Covid-19 dummy control variable. The study used a quantitative approach with quarterly panel data on nine banks listed on the Indonesia Stock Exchange, and was analyzed using a fixed effects model with robust standard errors. The results show that CAR and PBV significantly influence stock prices, while ROE and NPL are insignificant. Simultaneously, all variables have a significant effect. These findings suggest that investors respond more to capital strength and valuation than to profitability and credit risk.

Abstract

The study aims to analyze the influence of consumption behavior, projected through cultural, social, personal, and psychological factors, through Generation Z's decision to use the Quick Response Code Indonesian Standard (QRIS). The focus subjects were taken from undergraduate students of Economics at Surabaya State University from 2021 to 2024 who are active users of QRIS. Using an associative quantitative approach using primary data to be collected using an online questionnaire distribution. The data analysis technique applied Structural Equation Modeling–Partial Least Square (SEM-PLS) using SmartPLS 4 software. The results of the study showed that four factors of consumption behavior, namely cultural factors, social factors, personal factors, and psychological factors, have a positive and significant impact on students' decisions to use QRIS. Evaluation of the F-square value F2 shows that psychological factors (internal motivation, perceived ease, security, and trust) are the most dominant predictors with the largest effect value of 0.434 in influencing the decision to adopt this digital payment system technology. These findings indicate that a combination of students' internal motivation, the digital culture inherent in the campus environment, and the demands of practicality in Generation Z's lifestyle strengthen the decision to use QRIS in daily economic activities.
