The students should passes the various lecturing system, one of them is the process of carrying out the task by the lecturer [1]. During carrying out the assignment, the students should do and collect the assignment on time so the learning process and each academic stage can be finished on time. The students often meet various problems which hinder the academic assignment completion. One of the problem is encountered by the students is delaying the academic assignment completion. The delaying is one of the characteristic of procrastination [2]. It is similar to Dryden [3] opinion who stated when carrying out the assignment, the students often act procrastination. According to Kim and Seo [4], procrastination is the delaying assignment completion phenomena or delaying learning commonly happened in students circle whereas procrastination is unfavorable [5]. According to Ferrari and Morales [6], academic procrastination is giving more negative than positive impact. Procrastination by inidividuals tend to cause problems [7], for instance, the reducing of responsibility and individual will to do the assignment [8], which gives much bad impact of the drop achievement [9],[10]. Saleem, Bashir, Ameen, and Noor [11] research shows that significantly, it influences to individual self-regulation failure. It also increases the stress related to college assignments [12], positively related to fatigue when doing the assignment [13], and influence the academic performance [14]. Even though the procrastination has various negative impacts but some individuals are unaware of the consequences of its negative impacts [15]. It is caused by the assumption that if an individual starts to do the assignment in last minute, the individual is able to complete the task on time [16]. First actual historical analysis of procrastination was written by Milgram and Ravi [17]. Otherwise based on Ferrari, Johnson, and McCown [18] procrastination had been existed over history but previously it seen as neutral and wise actions. As the time passed by, in procrastination modern era is assumed as illness [19]. Solomon and Rothblum [20] opined that procrastination is being important to investigate because the procratination frequency is high and causing damage to doers. Burka and Yuen [21] stated the procrastination is from ―procrastinate‖ is delaying a work until the next time or day . Solomon and Rothblum [20] define procrastination as the delaying tendency to start finishing the assignment by doing other useless activity so the assignment obstructed and unfinished on time. Procrastination is the tendency to avoid and delay activities on time [22]. Same with Ferrari [23] opinion, he defined procrastination as the delaying tendency of doing or completing assignments. Meanwhile, it can be interpreted as intentional delaying activities of the desired activities even the individual realize it can induce bad impact [24]. In past decade, procrastination empirical study shows that it can influence self-efficacy [25],[26],[27], academic motivation [28], self-control [29], emotional intelligence [30], attention and emotional regulation [31]. The previous research discussed the procratination behaviour phonomena which majority focused to academic procrastination [32]. For instance, the research is done by Chowdhury and Pychyl [33] which refers to Haghbin and Pychyl theory [34]. The research uses Delay Questionaire scale as data collecting instrument. The further research by Wohl, Pychyl, and Bennett [35] it refers to procrastination theory according to Steel [24]. Meanwhile, in this research, procrastination uses Ferrari [23]. Ferrari, Johnson, and McCown [18] said there are four procrastination aspects. Those are perceived time, intention- action, emotional distress, and perceived ability. Perceived time is present oriented individual behaviour and not considering future which is showed by individual behaviour who likes to delay work and fail to complete task due deadline. Intention-action is the gap between will and action where the individual is unable to do the task based on the plan and finds the difficulty to do something due to the deadline. Emotional distress is worried feeling when procrastinating, the feeling discomfort the doer but the individual feels calm when the time of doing task is considered a lot. Perceiver ability is the belief of self-capability, included the doubt to self-capability and afraid of failure so individual doesn’t want to start doing task. ————————————————  Melda Werty, Master in Psychology Ahmad Dahlan University, Yogyakarta, E-mail: halomelpsy@gmail.com  Fatwa Tentama, Master in Psychology Ahmad Dahlan University, Yogyakarta, PH-081904100008.  E-mail: fatwa.tentama@psy.uad.ac.id
