The phenomenon of academic procrastination generally occurs because of a tendency to delay starting, implementing and ending an activity that occurs in an academic environment. The study aimed to determine the effect of self-efficacy and perceptions of social support on academic procrastination on students at the final level of University X. The research participants involved were 73 students at one University in Depok, West Java. To test the hypothesis about the effect of self-efficacy and perceived social support for procrastination, analysis was done using multiple regression analysis techniques. The results showed that there was an effect of self-efficacy, perceived social support, with academic procrastination. Student academic procrastination will increase, if their self-efficacy and social support are decreased. When the students’ self-efficacy decreases, the procrastination will increase. Likewise, when the social support they feel decreases, the procrastination will increase.
