<![CDATA[This study aims to analyze the effect of Big Five Personality and self-efficacy on academic procrastination among final-year students of the Faculty of Economics and Business, Universitas Teuku Umar. This research employed a quantitative approach with a causal associative design. The population consisted of 281 final-year students, with a sample of 74 respondents determined using the Slovin formula at a 10% margin of error. The sampling technique used was probability sampling with the simple random sampling method. Data were collected through a Likert-scale questionnaire and analyzed using multiple linear regression with SPSS version 24. The results show that openness to experience has a positive and significant effect on academic procrastination, while conscientiousness has a negative and significant effect. Meanwhile, extraversion, agreeableness, neuroticism, and self-efficacy do not have a significant effect on academic procrastination. These findings indicate that academic procrastination among final-year students is more strongly explained by openness to new experiences and self-discipline.]]>
