The consumptive behavior of students tends to be excessive. Therefore, this study aims to test the impact of financial literacy, peer group, social media usage, and locus of control on students’ consumption behavior. The population consists of 41,061 active S-1 students of Universitas Negeri Semarang, Jawa Tengah, Indonesia. 5% of 398 samples had an error rate using the Slovin formula. Primary data were collected through surveys employing a 5-point Likert scale. The questionnaire constructed in Google Forms was distributed using WhatsApp group. The data collected were then subjected to validity and reliability tests. Thus, the response variable was consumptive behavior; three predictor variables were financial literacy, peer group, and social media usage; and the mediating variable was locus of control. The results show that financial literacy affects consumptive behavior negatively, with a coefficient of –0.109 and a significance value of 0.041. Peer groups, social media usage, and locus of control had a positive and significant effect on consumptive behavior directly. The coefficients were 0.039, 0.518, and 0.218, with significance values of 0.031, 0.000, and 0.000. Financial literacy and peer groups have a positive and significant effect on the locus of control with coefficients of 0.0638 and 0.251 and significance values of 0.000. In addition, locus of control has been proven as a mediator in the influence of financial literacy and peer groups on consumptive behavior.

Islamic banking has existed in Indonesia since 1992. The performance of Islamic banking is interesting for further analysis. This study aims to analyze the impact of good corporate governance (GCG) implementation and bank characteristics on the performance of Islamic banking in Indonesia before the COVID-19 pandemic. Profitability is a measure of banking performance and is proxied by return on assets (ROA) and return on equity (ROE). The research sample consists of Islamic commercial banks that published financial and annual reports between 2011 and 2019. The data collection method used is documentation. Multiple regression analysis was used for data analysis. The results indicate that the implementation of GCG has no significant impact on performance (probability values of 0.425 and 0.420 on ROA and ROE with coefficients of 0.016 and 0.019). The P-value of the non-performing loans (NPF) variable is < 0.001 on ROA and ROE, which means that NPF has a significant negative impact on ROA and ROE. Third-party funds only have a significant impact on ROE with a p-value of 0.046. Meanwhile, the size of a bank has not been shown to have a significant impact on the performance of Islamic banking in Indonesia. Efforts to maintain NPF are critical for banks to achieve good performance (profitability). NPF demonstrates the risk of nonpayment of Islamic bank financing.
