Introduction
Humans have various types of needs that are increasing and complex. One of the important needs is the need for education. However, to pursue higher education is not easy, a student must meet various kinds of obligations, such as paying for university, buying stationery, buying textbooks, photocopying fees, training costs, and other expenses related to the university. Not to mention added to the cost of daily necessities such as meals, boarding fees, gasoline, and others [1].
Given the very diverse and increasing needs of students, parents no longer able to bear the overall costs of higher education [2]. This makes students have to find ways to meet all their needs, both the needs for education and daily needs. There are students who decide to go to university while working to meet those needs. However, so that they are still able to carry out lecture activities, the work taken by students in general is a type of work such as part-time work [3]. The phenomenon of working students is called the dual role phenomenon [4].
Besides the desire to live independently so as not to depend on parents, there are many other things that made students choose to do a part-time job which are filling their free time on the sidelines of lecture schedules, looking for non-academic experiences, or just doing a hobby [5].
However, carrying out the obligation to study and also have to work certainly will not be easy for a student. CNN Indonesia said on its website that students who work tend to experience mental problems. Dadgar (2014) also found another fact that students who were unable to balance work and college activities were one of the reasons that influenced the dropout rate [6]. This shows that work activities affect the activity of college students themselves.
This is because there are two demands in two different places. A student who works will experience a dual role conflict in meeting the demands of his role as a student and also as an employee. This circumstances could have negative impacts such as decreased mood, decreased level of physical health, decreased productivity and substance abuse [7]. Even worse if the stress due to role conflict is not immediately resolved and continues for a long time will result in burnout. This causes a student who also works will experience stress which will affect his well-being [8].
There are several factors that affect psychological well-being, so that not everyone has the same level of psychological well-being. Existing studies show that there is no single determinant and welfare. Some conditions seem necessary for achieving high psychological well-being such as mental health and positive social relationships [9]. Based on the opinion of Yasin & Dzulkifli (2010) that there is a relationship between social support and psychological well-being of students [10].
Social support itself is a variety of resources provided by others to individuals that can affect the welfare of the individual concerned [11]. Sarafino (2002) says social support can take the form of several forms such as emotional support, appreciation support, instrumental support, information support, and social network support [12]. The benefits and social support is to reduce anxiety, depression, and symptoms of bodily disorders for people who experience stress [13]. Individuals who have high social support will have positive experiences in their lives, such as high self-esteem, and lower anxiety levels so as to increase the level of psychological well-being.
Measurement of social support itself is not easy because social support is considered as something useful when the individual needs and perceives the availability and social support [14]. The same opinion was expressed by Barrea (1981) that well-being correlates with subjective aspects and social support. This means that the individual's perception of social support is a more important factor than the form or amount of social support received by the individual [15].
The importance of social support in increasing psychological well-being need especially for students that have a part-time job while studying need to be explore. Therefore, researchers conducted further research on the relationship between social support and psychological well-being of students working part-time.

A negative value on skewness indicates that the variable data distribution curve has a tendency towards the left. The value of kurtosis on the variables of psychological well-being and social support is -0.116 and 1,498. The value of kurtosis represents the sharpness of the data distribution curve. In the table above shows the complete amount of data that is 65 data and no missing data.

Discussion
This study proves that there is a significant relationship between social support and psychological well-being. The result is in line with the previous study conducted by Yasin & Dzulkifli (2010) that there is a relationship between social support and psychological wellbeing of students [10]. Cohen and Syme (2005) has come to the same conclusion that social support is closely related to psychological well-being [11].
Research shown that students that received a high social support will have high level of psychological wellbeing. Apollo & Cahyadi (2012) found that the benefits of social support are to reduce anxiety, depression, and symptoms of bodily disorders for people who experience stress [13]. Therefore, individuals who get high social support will have positive experiences in their lives, such as high self-esteem, and lower levels of anxiety, so as to increase psychological well-being.
Given that students who work part-time are individuals who are vulnerable to mental disorders because they have to work on two roles simultaneously. In this context, social support is an important external factor that could help them in improving their psychological well-being.
