: This study aims: to test and analyze the influence of leadership style, employee commitment, work motivation, and work climate on employee job satisfaction with direct and indirect effects. This study uses primary data from a survey of 221 employees as sample. Data were analyzed using Structural Equation Modeling (SEM) with AMOS. The results showed that: (1) empirically, the leadership style, employees commitment, work motivation, and work climate had a positive and significant effect on job satisfaction; (2) employees commitment, work motivation, and work climate have a positive and significant effect on employees performance through job satisfaction as an intervening variable, while leadership style has no significant effect; (3) employee commitment, work motivation, and work climate indirectly have a positive and significant effect on employees performance through job satisfaction as an intervening variable, while the leadership style has no significant effect; and (4) job satisfaction has a positive and significant direct influence on employees performance. This study suggested that work motivation, employee commitment, and work climate that provide significant influence need to be maintained, while leadership styles that have insignificant influence on employee performance need to be improved and prioritized as the company's efforts to improve job satisfaction and employee performance.


INTRODUCTION
Development in all fields is the main goal that is being actively implemented to create a just and prosperous society. Thus, by opening the most comprehensive possible business opportunities by the government to the public, the development of the national business world today grows and develops rapidly. Various types of business entities, both government and private companies, continue to emerge. By itself, the development of the business world is increasingly colored by increasingly fierce competition. The position of human resources in the company is significant (Tefera & Hunsaker, 2020). Therefore, human resource management is needed so that human resource management can run as expected by the company. Workers are human beings who have different characteristics and characteristics. In carrying out the tasks assigned to him, it takes a strong workforce, competent, has high discipline and dedication to show high performance in carrying out their duties (Liu & Huang, 2020). Thus, efficient and effective employees will be created so that they can carry out tasks and work based on predetermined work lines or work standards or in other words, efficient and effective employees are employees who work following work standards, namely discipline and on time, full of initiative in carrying out tasks without waiting for orders from leaders (Ronay et al., 2020).
Each company has specific goals according to their respective business fields, but the main target to be achieved is profit and other purposes, such as continuity of company life and participation in improving the community's welfare. For that, a company that wants to maintain its existence better, then the essential thing is the ability of the company's leadership to manage all existing potential effectively and efficiently, and the utilization of the current workforce will affect the improvement of employee performance, including employees at PT Semen Tonasa. PT Semen Tonasa is one of the companies engaged in the production and marketing of cement. This company always strives to improve itself through continuous evaluation and development. With the support of human resources and solid capital, it synergized with the strength of a reliable managerial strategy. This improvement is expected to create sustainable growth in the company's profitability. PT Semen Tonasa carries a vision: "To become a leading cement company in Indonesia with a high level of efficiency." Meanwhile, the missions carried out are: Increasing the company's value according to the wishes of stakeholders. Producing cement to meet consumer needs with competitive quality and price and timely delivery. Always striving to make improvements in all fields to increase competitiveness in the market and company productivity and build a work environment that can arouse employee motivation to work professionally. To realize the vision and mission it carries, it must be supported by the ability of human resources as one of the determining factors for its success. Human resources are significant and have a strategic role in formulating and implementing company policies. Human resources are a precious organizational asset and play an essential role in the company's survival. The basic strategy needed to improve and empower the potential of human resources in the organization is to foster and enhance the quality of human resources so that they can work professionally following the tasks and functions assigned to them. PT Semen Tonasa maintains product quality so that the price can be higher because every consumer country always wants quality cement. The success achieved by PT Semen Tonasa in increasing the volume of cement sales, thanks to the implementation of efficient and effective work, has continuously shown improvement despite increasingly fierce competition, both in foreign markets and in the domestic market itself. PT Semen Tonasa's products are very well known in the market, as evidenced by the growth in sales per year, with an average of 17.33 percent.
The development of cement sales at PT Semen Tonasa from 2012 to 2016 tends to fluctuate. In 2014, cement sales growth decreased by 8.47%, but in subsequent years, it increased to 26.13% in 2016. Efforts to improve the company's performance must, of course, be supported by the quality and quantity of its employees. In connection with the achievement of employee performance at PT Semen Tonasa, which has not been in line with expectations, it cannot be separated from the influence of ineffective leadership style factors, low commitment, and work motivation of employees, and an inadequate work climate. This can be seen from several aspects, including that, in general, all routine activities. However, while they can be completed according to the specified schedule, the quantity and quality of work results are not as expected. Therefore, efforts are needed to improve employee performance thru effective leadership, strong employee commitment, high work motivation, and a conducive work climate. Thus, the factors of leadership style, employee commitment, work motivation, and work climate are independent variables that need to be studied to determine their effect on job satisfaction and employee performance at PT Semen Tonasa.

Literature Review
A leadership style is a behavioral norm used by a person when that person tries to influence the behavior of others Treuren & Fein, 2021). The leadership style is suitable when the company's goals have been communicated, and subordinates accept them. A leader must apply a leadership style to manage his assistants because a leader will significantly affect the organization's success in achieving its goals (Swanson et al., 2020). Companies use rewards or gifts and orders as a tool to motivate employees. Leaders hear ideas from subordinates before making decisions. The right leadership style will lead to a person's motivation to excel. The success or failure of employees in work performance can be influenced by the leader's leadership style (Super, 2020). Feng et al. (2020) have proven that leadership style significantly influences employee performance. The relationship between the leader and his subordinates is very close; therefore, the success of a leader in managing the organization will not be separated from the role of his associates and the leadership style he applies. A leadership style is a behavioral norm used by a person when trying to influence the behavior of others. According Feng et al. (2020), leadership style is a combination of behavior and strategy due to a combination of philosophy, skills, traits, and attitudes that are often applied by a leader when trying to influence his subordinates. The involvement of leadership style in triggering individual performance is a very significant value and price in operating an organization. Therefore, the relationship between leadership style and performance is a tolerant law that must be adhered to by every leader who wishes to exceed targets, both time and things to be achieved in a work organization. So that the performance of each individual responsible for the organization is obligatory to receive guidance from the leader as stated in the leadership system, he adheres to (Haar et al., 2022). Leadership style is seen as a personality that can influence others. Like the leadership of Rasulullah has extraordinary abilities that can arouse the admiration of many people toward him. According to Ciobanu & Androniceanu (2015), leadership styles are various patterns of behavior favored by leaders in directing and influencing workers. The relationship between leadership style and job satisfaction is based on path-goal theory. The influence of leader behavior on employe satisfaction depends on aspects of the situation, including job characteristics and employee characteristics.
Furthermore, job satisfaction and leadership style are the most important elements that affect the organization's overall effectiveness. González-Cruz et al. (2019) states a positive influence between leadership style on job satisfaction and employee performance. In addition, research that is also related to the impact of leadership style on job satisfaction and employee performance, among others: evidenced by Adiguzel et al. (2020) whose results conclude that leadership has a positive and significant effect on job satisfaction and employee performance. Meanwhile, Fernando et al. (2020) proved that leadership has a negative and significant impact on employee performance. In line with the leadership role, employee commitment is also a predictor of job satisfaction and employee performance. Employees who have a high work commitment are needed to achieve maximum individual performance. Markos et al. (2010) suggest that commitment is defined as the identification power of individuals within an organization. The mapping of the results of previous studies, which became the research gap or gaps in this research, can be seen in Table 1. There are differences in the findings of the influence of leadership style on job satisfaction and employee performance Leadership style has a positive and significant effect on job satisfaction but has no significant effect on employee performance. Leadership style has no significant effect on employee performance through job satisfaction.

The concept of performance put forward by Zhang et al. (2020) is often referred to as performance, also called result, which means what has been produced by individual workers. Furthermore, Forster & Fenwick (2015) stated individual performance as a product of multiplication or a function of motivation and ability. In comparison, Ibrahim & Heng (2015) individual performance results from work that a person or group of people can achieve in an organization, following their respective authorities and responsibilities to achieve organizational goals legally, not violating the law following morals and ethics. Cook et al. (2020) proposed six primary criteria that can be used to measure performance: quality, quantity, timeliness, cost-effectiveness, need for supervision, and interpersonal relationships. Furthermore, Ibrahim & Heng (2015) suggests several ways to measure individual performance, including the quantity of work, quality of work, knowledge of work, opinions or statements submitted, decisions are taken, work planning, and work areas. Meanwhile, Miller et al. (2021) states that the performance appraisal criteria include: quantity of work, quality of work, job knowledge, creativeness, cooperative, dependability, initiative, and personal quality. The same thing was also stated by Tefera & Hunsaker (2020), performance measurements include work performance, responsibility, obedience, honesty, and cooperation. The performance appraisal aspect is a trait or characteristic that can indicate the implementation of a particular job to run smoothly and work well to support employee performance improvement. Thus, the performance measurement criteria used in this study include (1) work quality, (2) work quantity, (3) work creativity, (4) work effectiveness, (5) timely completion of tasks, (6) supervision, and (7) cooperation. The performance measurement is an indicator because it is believed to improve employee performance The concept of leadership style proposed by Georgakakis & Buyl, (2020) is how a leader carries out his leadership function and how he is seen by those he is trying to lead or those who may be observing from the outside. Path-Goal Theory state that leaders encourage higher performance by motivating subordinates to believe that hard work can achieve valuable results. Universally applicable leadership results in high levels of subordinate performance and satisfaction. This theory states that different situations require different leadership styles. Subordinates with an internal locus of control will have higher job satisfaction with a participatory leadership style. In contrast, assistants with an external locus of power will have a more directive style. Path-Goal theory explains that the behavior of the directive style leader, supportive style, participatory style, caregiver style, and achievement orientation kind affect these expectations. So, it affects the work performance of subordinates and the performance of subordinates. By using one of the four styles, a leader must try to influence subordinates' perceptions and motivate them about task clarity, goal achievement, job satisfaction, and effective performance González-Cruz et al. (2019). These five aspects are the basis for measuring leadership style in this study to know its effect on employee performance The concept of commitment, according to Hu et al. (2020), is the relative strength of individuals in identifying employee involvement in the organization, including the desire to maintain membership in the organization, readiness, and willingness to make serious efforts on behalf of the organization, and acceptance of the values of the organization. Furthermore, Schwepker & Dimitriou, (2021) propose a final typology of employee commitment. There are three commitments put forward, namely affective commitment (affective commitment), continuance commitment (continuance commitment), and normative commitment (normative commitment). Affective commitment is related to employees' emotional attachment, employee identification, and employee involvement in the organization. Continuity commitment is associated with the desire to continue working or leaving the organization. Normative commitment relates to the feeling of obligation to remain in the organization.
The concept of work motivation proposed by Palma et al. (2021), that the motive to drive the effort to satisfy a want or good (motivation refers to the drive and effort to fulfill a need or a goal). Furthermore, the concept of motivation which refers to Herzberg's theory in Burritt et al. (2019), suggests a theory of motivation known as the theory of two factors rather than job satisfaction. There are 2 (two) sets of conditions that affect a person in his work, namely: (1) motivator factors; and (2) hygiene factors. It was further stated that the factors that act as motivators for employees, namely being able to satisfy and encourage people to work well, consist of (1) Achievement (successful implementation); (2) Recognition; (3) The work itself; (4) Responsibilities (responsibility); and (5) Advancement. This set of factors describes a person's relationship with what he does: The content of his work; Performance in his duties; Appreciation for his achievements; Improvement in his duties. Therefore, the five factors can satisfy and encourage employees to work well: successful implementation, recognition, work itself, responsibility, and development as measurement indicators because they are believed to be able to form employee motivation variables. The concept of work climate, according to Costantino et al. (2021), is a productive condition to create internal and external situations to get work optimization from a performance. The creation of internal conditions must be conducive, fun, and exciting. The work climate automatically and goals play a role. So, the work climate is everything around the workers that can affect them carrying out the assigned tasks.
According to Cho et al. (2020), the work climate is essential in implementing employee duties. A pleasant working environment will improve employee performance. Therefore, the work climate in the company is significant for management to pay attention to because a work climate that focuses on employees can increase their satisfaction and performance. The indicators for measuring work climate are: Air temperature in the workspace; Lighting in the workspace; The noise around the workplace; Air circulation in the workplace; Guarantee of workspace privacy; Size of the workspace; Arrangement of the layout of the workspace; Relations with co-workers.
Job satisfaction is a positive or pleasant emotional statement resulting from assessing a job or work experience (Forster & Fenwick, 2015). Tajeddini et al. (2020) suggests that the factors that influence the emergence of high levels of employee job satisfaction are: 1) challenging work; 2) proper compensation; 3) supportive working conditions; 4) co-worker support; and 5) partner support. These factors are used as dimensions in this study. For more details, the conceptual framework scheme in this study can be seen in Figure 1.

Data Samples
This research will be conducted at PT Semen Tonasa, South Sulawesi Province. Then the research was conducted for four months, namely: March to July 2021. The population in this study was all administration department employees at PT Semen Tonasa. The people or universe is the total number of units of analysis whose characteristics will be estimated. The people can be divided into two groups: the sampling population and the target population. The population in this study is a sampling population, namely: the number of staff employees of the President Director, Staff of the Director of Finance and Commercial, as well as affiliated staff and others. The total population in this study was 495 employees. Furthermore, a sampling technique was used based on a predetermined population source to determine the sample of employees in three departments (administrative division) at PT Semen Tonasa. The sampling method obtained 221 employees. The size of the sample members of each department is determined by fraction sample based on the number of employees of each department. The data collection method used in this study is observation, namely collecting data through direct observation of leadership styles, employee commitment, work motivation, work climate, job satisfaction, and employee performance to obtain data related to this research. A questionnaire (questionnaire) collects data by distributing a list of questions to respondents.

Measurement
The grouping of variables is done into two parts: explanatory variables (exogenous) and explained variables (endogenous). The explanatory variables (exogenous) are leadership style, employee commitment, work motivation, work climate. In contrast, the explained variables (endogenous) are job satisfaction as an intervening variable and employee performance as an endogenous/dependent variable. The testing phase is to test the instrument's validity, reliability, reliability of the instrument is measured by Cronbach's alpha, i.e., if Cronbach's alpha coefficient > 0.60, it means that the instrument is reliable and fulfills the reliability requirements. However, Cronbach's alpha < 0.60 means the instrument is unreliable (Hair et al., 1998:118). The coefficient of determination (R2), if R2 is very high (e.g., between 0.7 -1) and none of the regression coefficients are significant, then statistically, this means that multicollinearity symptoms occur. Looking at the Variance Inflating Factor (VIF) value, if the VIF value is less than 10, then multicollinearity symptoms do not occur, but if the VIF value 10 means there are multicollinearity symptoms. The measurement of variables using a Likert scale (1 = strongly disagree, 2 = disagree, 3 = neutral, 4 = agree, 5 = strongly agree). Measurement items as shown in table 3.

Descriptive Analysis
Characteristics of respondents can be seen from the results of research conducted on a sample of employees of PT Semen Tonasa, amounting to 221 respondents, which include: gender, age level, education level, and years of service. The characteristics of the respondents can be explained in table 3. Furthermore, the results of the validity and reliability tests of each variable statement item in this study can be seen in Table 4. Based on the data in Table 4, it can be explained that of the six variables used in this study, the Corrected Item Total Correlation value was obtained between 0.631 -0.875 so that it can be said that the results of validity and reliability testing showed that all indicators used to measure each variable met the requirements > 0.60.

Statistical Result
The final model test of the relationship between leadership style, employee commitment, work motivation, and work climate on job satisfaction and employee performance in full is presented in Figure 2.

Figure 2. The SEM Model at the Final Stage
Based on the picture above, it can be explained that the results of the goodness of fit analysis of the complete SEM model at the final stage show that there is a synergistic relationship between the variables of leadership style, employee commitment, work motivation, work climate, with job satisfaction and employee performance. The goodness of fit criteria analysis results for the complete SEM model can be seen in Table 5. Based on the data in Table 5, it can be explained that the relationship between variables in the complete model at the final stage shows a good fit. Thus, the causal relationship between each tested variable can be accepted and used for further purposes. The results of the estimation of the regression coefficient values of the functional relationship between the independent variables and the dependent variable in the SEM model can be seen in Table 6.  Based on the data in Table 7, it can be interpreted that the results of testing the direct effect, indirect effect, and total effect between variables are also empirical findings from this study; all variables have a positive and significant impact except for hypothesis 9.

Discussion
A leader's style is a pattern of behavior that the leader uses to influence, direct, and guide subordinates to carry out all the main task mechanisms effectively and efficiently. Therefore, to increase job satisfaction and employee performance in an organization, it is necessary for an employee who has an effective leadership style to work well. The complete SEM model test results show that the leadership style variable has a positive and significant effect on job satisfaction. This is indicated by the critical ratio and probability values as required. This means that the two variables have a positive and significant causal relationship. The positive influence of the leadership style variable on job satisfaction is determined by the ten indicators that make it up. Indicators of leaders who are always willing when subordinates consult them can form leadership style variables, meaning that the needles in the model can significantly measure leadership style because leaders are always willing when subordinates consult them.

While using a participatory manner, caregiver style, and directive style is still less than optimal, managers make all work-related decisions and instruct subordinates to carry out them by directly participating, guiding, and directing in carrying out tasks so that assistants can complete the job well required. This means that leaders need to participate, guide directly, and control their associates effectively, especially those with less working knowledge. Meanwhile, the supportive and achievementoriented styles can only be applied directly to employees who have adequate work knowledge. Thus, the leadership style can support employee performance improvement in the future.

Conclusion
