ABSTRACT


INTRODUCTION
The success of the company is the most valuable asset for human resources in improving welfare which is seen based on the quality and systems contained in the company.Human resources as initial capital to achieve company goals by providing invaluable contributions in carrying out every work activity.Human resources as drivers must have a developing, creative, quality potential in doing work and be responsible [1], [2].The role of human resources becomes very important because it is a factor in carrying out activities in each company [3].
The company in achieving its goals must be able to maintain the results that have been achieved, evaluate from the strengths and weaknesses it has, as well as policies and decisions that are carried out properly and appropriately [4], [5].The policy aims at human resources in increasing the productivity of work carried out by human resource management.Human resource management is related to employment which affects the level of work success of employees and companies.This is done so that human resource activities are carried out effectively and efficiently and are able to increase work productivity [6], [7].
A company wants high productivity this requires directed work planning so that work productivity can increase and the results obtained are in accordance with the company's goals set, if these goals are not achieved effectively and efficiently then the employee's work productivity is low [8].High productivity is the company's goal in making a profit [9].The higher the product results obtained in a short time, the higher the value of the work productivity of its employees [10].Work productivity as a relationship in the production system between inputs and outputs.Productivity is related to the use of resources that reflect the company's success in achieving the results of Berberoglu's work (2018) [11].The reality on the ground is that there are differences with this idealism as explained in table 1.Based on table 1 above, it can be seen that there is a decrease in employee work production achievement in 2021.The decline in productivity seen from the percentage in January to April decreased from 87% to 82% while in May it experienced an increase of 85%, but in June to December it continued to decrease by 82% to 52%.Based on the percentage of employee work productivity achievement that has decreased, this is due to the inability of employees to achieve the targets set by the company.A decrease in production will be able to affect market competition.This requires companies to be more careful in providing goods for quality market demand and satisfying customers.High productivity will help the company in achieving its goals [12], [13].
One of the dominant factors that can affect work productivity is the supervision factor.The supervision factor within the company is usually carried out by the superiors of each employee, because the superiors know more directly.A superior provides supervision to employees so as not to make mistakes or negligence of their work.Work supervision aims to make the results of work implementation in accordance with previously established planning effectively and efficiently [14], [15].Supervision is carried out as a way, guiding, improving refreshment, encouraging and supervising certain employees in the hope of seeking cooperation so that the superior is successful in supervising.The findings are also supported by Adikoeswanto et al. (2020) [16] that supervision can affect work productivity.
Research conducted by Alkahtani et.all (2019) [17] and Al-Jabari & Ghazzawi (2019) [18] shows that organizational culture has no impact on work productivity.This is different from the research that has been carried out by Jehanzeb et all.(2018) [19] which revealed that organizational culture is able to affect employee work productivity.With the differences in the results of the research, this study will still be carried out in accordance with the phenomena that occur in the field by adding organizational commitment as a mediation variable [20].
Organizational commitment is a variable that can strengthen organizational culture towards employee work productivity, this is evidenced by the findings of Edward & Purba (2020) [21].A committed employee will work as much as possible and devote his attention, thoughts, energy and time to his work so that it will increase his productivity.This finding is also supported by Arif et all.(2019) [22] and Loan (2020) [12] which reveals that organizational commitment has a significant effect on employee work productivity.
Departing from the gaps and phenomena that occur, this study will test the Influence of Supervision and Organizational Culture on Employee Work Productivity through Organizational Commitment to Kimshafi Alung Cipta Ltd.The importance of this research is because if employee work productivity is getting better, it has an impact on the existence and profitability of the company.Therefore, this study will examine how much influence supervision has on employee work productivity directly, organizational culture on employee work productivity directly and supervision, organizational culture indirectly through organizational commitment as a variable mediation.Penelitian ini merupakan kebaruan dari previous research by adding the variable of organizational commitment as a variable mediation.
