One of the reasons the Sugar Factory failed to meet its sugar production target was due to damage to the machine components, particularly at the milling station, where the milling rollers are located. The milling rollers play a crucial role in extracting juice from sugar cane, separating the juice from the bagasse, and measuring the raw juice before it enters the purification process. This unit is designed to maximize raw juice yield while minimizing the amount of bagasse. The milling rollers are arranged in a triangular configuration of three mills, with a milling path between the front and rear rollers that can move forward and backward. Several common issues affect the milling rollers, including surface wear, damage from excessive loads, and wear from repeated friction between the rollers and the sugar cane. Sugar cane itself contributes to roller wear due to its composition, which includes water, sucrose, cellulose, lignin, hemicellulose, ash, and silica. These substances are highly corrosive, even to stainless steel, and act like abrasives against the rollers. The usual remedy at the factory is to weld stainless steel onto cast iron rollers. However, this method has only been moderately effective, as the rollers continue to experience wear after a short period. Based on field observations and literature reviews, some suggested solutions include more frequent cleaning and applying a tungsten coating to the roller surfaces.

The third, fifth, and sixth hypotheses are accepted where each variable such as audit experience, independence moderates the effect of time pressure on audit quality, and independence moderates the effect of audit experience on audit quality.

This research has the objective of analyzing the relationship between the work environment, work culture and workload related to employee performance in an agency or company. This research uses quantitative methods through descriptive analysis, as well as online data collection using the Microsoft Forms Platform with a Likert scale of 1 to 5 with the Purposive Sampling method, there are 57 respondents with the age criteria 18-30 and currently working. Processed using the SmartPLS 4.0.9.2 application program. with Structural Eqution Modeling (SEM). The results showed that, the work environment is influential in supporting or improving the performance of its employees for the better and can produce quality work done by its employees. The work environment can be maximized when a company can implement or create a conducive, collaborative environment, and pay attention to all aspects such as the physical and psychological of its employees. Such factors as sufficient facilities, social support, and job security can increase employee performance productivity. Organizational work culture also plays an important role in shaping employee performance. Organizations with a culture that encourages innovation, collaboration, and employee motivation have better performance. Conversely, a work culture that does not support employees can hinder employee performance. Workload in accordance with individual capacity also affects employee performance. Too high a workload can lead to excessive stress and fatigue, which negatively impacts productivity. Therefore, wise management in determining workload is essential. From this study, it can be concluded that a good work environment, positive work culture, and workload adjustment can significantly improve employee performance. A company or an agency needs to pay attention to these factors to achieve optimal productivity and job satisfaction in the midst of intense competition between agencies.
