As previously mentioned, the performance of a company to achieve its goals is influenced by the performance of its existing employees within the company itself.The employee performance according to Mangkunegara (2008), is the quality of A research conducted by Irawati (2015) and Mukuan (2014) states that the quality of work life is a factor that has to be considered by the company management because it surely affects the employee performance.Kristianto, Suharnomo, & Ratnawati (2011) also mentions that job satisfaction has positive and significant impact on employee performance and organizational commitment.Nurandini & Lataruva (2014) explain that organizational commitment includes affective commitment, continuous commitment and normative commitment that provenly can influence the employee performance.Affective commitment has the greatest impact on employee performance.In accordance with the studies conducted by Parinding (2015) and Sapitri (2016), they found similar results from their respective studies, for instance organizational commitment consisted of affective commitment, continuous commitment, and normative commitment that had a positive and significant impact on employee performance.Adiftiya (2014) in his research also states that there is an influence between organizational commitment and employee performance.
But it has a low level of relationship.The quality of work life, job satisfaction, and commitment also provenly affect employee performance (Lumbantoruan, 2015).
PT. Madubaru PG-PS Madukismo conducts employee performance appraisal once a year.The performance appraisal aims to determine about how far the employees successfully working and completing their tasks during the employment period determined by the company.
The performance appraisal is implemented to each employee by assigning Ex (Excellent), G (Good), E (Enough) and L (Less).The employee performance target expected by the company is the result of the performance appraisal of the employees with the score of Ex (Excellent) and G (Good) which is minimally 50% or half of the total employee in the company during each assessment period.
From table 1 it can be defined that the employee performance was decreasing from 2011-2016.Therefore the management needs to pay attention to things that affect employee performance, so it can create policies that will improve employee performance.

Outliers Test
The resulting mahalanobis distance value is x 2 (68, 0.001) = 109.791.The result of the outonobobic distance outlier test is known that no dalanquin value of d-squared is above 109.791thus it is said to be multivariately no outlier.

Multicollinearity Test
The multicollinearity test results can be determined by the determinant of sample covariance matrix by 0.000.
Because the value is 0, then it concludes multicollinearity, however it is still acceptable because the requirements of other SEM assumptions are fulfilled, are the number of samples is at least 100, and based on CFA test all items are valid (the invalid one was already deleted).

Goodness of Fit Model
The test results of goodnest of fit are as follows:   Irawati (2015) and Mukuan, (2014).But in this study, it was found that the quality of work life has no effect on employee performance.This may be due to the possibility that there is a greater influence of the independent (exogenous) variable on employee performance.There is an indirect influence between job work and quantity achieved by employees in performing their duties in accordance with the responsibilities that given to them by the company management.Factors that have a significant effect on employee performance are the understanding on SOP and work relationship.SOP understanding will bring employees to work in accordance with the expected performance.A good work relationship between employees INTRODUCTION A company which concerns on agricultural industry is a company engaged in the processing of raw materials from agricultural activities that are processed into finished goods.In a company there are a lot of manpower and factory machineries.The raising of competition in this globalization era forces the company to improve its product quality and employee performance in order to survive and keep developing.One of agriculture industry is sugar processing industry which is also called sugar factory.One of the companies engaged in this processing sugar is PT Madubaru PG-PS Madukismo in Yogyakarta.This Sugar Factory started producing in 1958 and the Spiritus Factory began producing in 1959.The sugar factory is still working now.The resources are everything that included in the company asset and used to achieve the company's goals.Employees are the main resource assets of an organization and between employees and management, provide motivation to employees to achieve the expected performance (Sudibyo, Hartono, & Maas, 2014).There are many factors that can affect the performance of employees including the quality of work life, organizational commitment and employee job satisfaction.According to research conducted by Arifin (2012), the quality of work life is very influential on the employee performance.There are three indicators in the measurement of quality of work life, those are innovative rewards system, work environment and employee restructuring.The quality of work life programs are implemented by treating employees fairly and supportively, opening all channels of communication and in all directions, offering employees the opportunity to participate in decisions that affect them and empower them to handle the tasks (Riady, 2009).Job satisfaction by Brayfield & Rothe (1951) is described as a person's perspective, both positive and negative about his/her work.(Robbins & Judge, 2008) define organizational commitment as the high involvement of individual employee, or taking a side with a particular job.A high organizational commitment means favoring the organization that recruits the individual.
