The conclusion of this research is that work experience has a positive effect on job satisfaction, work experience has a positive effect on work productivity, job satisfaction has a positive effect on work productivity, job satisfaction is a mediator between work experience and employee work productivity.


Introduction
Tofu is a food product processed with soybeans which is very well known in Indonesia.This processed ingredient has become one of the Favorite foods for Indonesian people.Tofu business in Indonesia has become one of the popular businesses, because tofu making is done using simple methods or technology.Therefore, the tofu industry is experiencing quite rapid development in both small scale and medium scale industries.The tofu factory company, let's call it the Z tofu factory, is a tofu production company located in Jombang district, in the Mojowarno sub-district in Gempol Hamlet, Japanan Village, Mojowarno District.Based on table 1, it shows that the raw materials produced for making products do not all become finished tofu products, every month there are damaged products from the production results.This shows that employee productivity is not optimal.Work productivity comes from the word productive which refers to all activities that generate use.If someone works, there are results, then it can be said that he is productive, the measure of labor that succeeds in creating a product within a certain time.While the productivity of a machine or device compares input in the form of machines and equipment, output can vary depending on the input element.Work productivity describes the quality of human resources (Swastika et al, 2022).Work productivity is influenced by work experience.Work experience shows that the workforce has worked according to their skills.Work experience will make employees have a greater understanding of their work (Pankhurst, 2010).Job satisfaction is the result of employees' perceptions about how well their work results are things that are considered important (Purnamasari & Palupiningdyah, 2017) productivity.This shows that there are still many employees who have little experience in their work.
In contrast to the opinion of Snow & Lukman (2018); Kurniawan & Rimas (2021) show that work experience has no effect on employee productivity.This shows that there are still many employees who have little experience in their work.In addition to work experience, productivity is influenced by job satisfaction.Work satisfaction is a person's feelings in a pleasant or unpleasant emotional condition that can affect certain work (Handoko, 2014).Job satisfaction according to Elbandiansyah ( 2019) is a guideline that comes from someone's thoughts both positive and negative about his work.Job satisfaction is something that is individual.Someone who tends to work passionately when satisfaction can be obtained from his work.Job satisfaction that is felt by everyone is not the same, each individual will have different levels of satisfaction according to the value system that applies to him (Widyastuti & Palupiningdyah, 2015).According to Lilia et al, (2020), Putri et al (2020), Slamet (2020); Erwin & Rosnaida (2021); Arief and Nisak (2022); Nidyawati (2022) explains that job satisfaction has a positive effect on work productivity.Job satisfaction can encourage individuals to achieve more perfect and higher productivity (Sururin et al., 2020).The existence of satisfaction in individuals can increase work productivity if the organization provides a good reaction to the results that have been completed by employees (Adiwinata & Sutanto, 2014).This situation shows that if the level of job satisfaction received by the workforce increases, their work productivity will also increase (Harrisma & Witjaksono, 2013).This is different from the opinion of Hapsari, et al (2014)

Research Method
This research uses a quantitative research type approach.This research uses an explanatory research method using a research questionnaire with a Likert scale.The population used by the researcher was all employees in the production section of the Z Tofu Factory.The sample used in this study used saturated sampling, which was all employees in the production section of the Tofu Factory, totaling 45 employees.Data analysis uses path analysis with SPSS.The variables used in this research are as follows: Variable Independent The independent variable in this research is work experience.Manulang (2013;15) work experience is the process of forming knowledge or skills about the methods of a job due to the employee's involvement in carrying out work tasks.According to Sedarmayanti (2013) indicators of work experience are: 1. Length of time/work period, which is a measure of the length of time or period of work that a person has had to understand the tasks well and be able to carry out the work well.
2. The level of knowledge and skills possessed, referring to concepts, principles, procedures, policies or other information required by employees.Meanwhile, skills refer to the physical abilities needed to achieve or carry out a job.
3. Mastery of work and equipment -the level of mastery of a person in implementing technical aspects of equipment and work techniques who is able to carry out his work with experience.

Variable Dependent
The dependent variable in this research is work productivity, which according to Kusriyanto (2016) states that productivity is a comparison between the results achieved and the participation of labor per unit of time.The role of labor here is the use of productivity resources.The productivity indicators in this research are an adaptation of the productivity indicators according to Sutrisno (2011), namely as follows: 1. Capability, namely the employee's ability to complete the tasks given by the company.
2. Work spirit, namely the employee's desire to do their work optimally.
3. Quality, namely the good and bad production results produced by employees.
4. Efficiency is the accuracy of employees in carrying out the work that has been done.

Variabel Mediasi
The mediating variable in this research is job satisfaction.Job satisfaction is an employee's attitude towards work which is related to the work situation, cooperation between employees, rewards received at work, and matters involving physical and psychological factors.According to Afandi (2018) job satisfaction indicators include, among others: 1. Job where the content of the work someone does has satisfying elements.
2. Wages, where the amount of payment a person receives as a result of carrying out work is in accordance with needs that are felt to be fair.
3. Promotion where the possibility of someone being able to develop through promotion.
4. Supervisor, who is someone who always gives orders or instructions in carrying out work.The conceptual framework in this research is as follows: The statistical equation for substructure path analysis 1 is as follows: The statistical equation for substructure path analysis 2 is as follows: The partial test used in this research uses a significance level of 5%, 1) If the significance value is ≤ 0.05 then the hypothesis is proven or significant, 2) If the significance value is ˃ 0.05 then the hypothesis is not proven or not significant.The value of e1 = √(1-R2) while the arrow from e2 towards financial performance shows the variance in financial performance that cannot be explained by the IC and CSR variables and the amount of e2 = √(1-R2).The path coefficient is the standardized regression coefficient (Ghozali, 2018).Mediation hypothesis testing can be done using a procedure developed by Sobel and known as the Sobel test.To make it easier to test the effect of mediation, the Sobel Test can be calculated via the Online Sobel Calculator.Based on the results of data processing, it shows that the significance value is 0.008 (0.008 < 0.05), meaning that the relationship between the variables of work experience and job satisfaction and the variable of employee work productivity is stated to be linear.

Regression Equations
The Influence of Work Experience on Job Satisfaction This regression equation means that work experience has a regression coefficient in a positive direction, meaning that the more the employee has more experience at work, the more satisfied the employee is in his job, and vice versa, the more the employee has little experience at work, the more the employee is dissatisfied with his job.The regression equation shows that: a. Work experience has a regression coefficient in a positive direction, meaning that the more experience an employee has at work, the higher the employee's work productivity, and vice versa, the more an employee does not have experience at work, the more the employee's work productivity decreases.

Mediation test
Based on the results of the mediation test analysis which has been carried out through the Sobel test, it can be seen that the job satisfaction variable is an intervening or mediating variable between work experience and employee work productivity.

Discussion
The Influence of Work Experience on Job Satisfaction Based on the results of the analysis, it shows that there is a significant positive influence of work experience on job satisfaction, meaning that the more employees have more experience at work, the more satisfied the employee is in their work, and vice versa, the more employees have little experience at work, the more dissatisfied the employee is in their work.Karyawan who has a lot of experience working in a tofu factory will certainly be more satisfied with the results of his work because factory employees already have the knowledge and skills on how to make quality tofu according to company standards.
Factory employees know that Z has knowledge and skills about the work they do, so this experience makes employees more satisfied with the results of their work.Z tofu factory employees have an average of more than 5 years of work experience so they do not need a lot of guidance from the leadership so that employees will try to improve their work results and will create a sense of satisfaction with the results of their work.This is in accordance with the opinion of Lubis ( 2019) which shows the results that experience has a positive and significant influence on job satisfaction.The results of this research are supported by research conducted by Wijaya & Suana (2014) which states that the more experience, the higher the level of job satisfaction.

The Influence of Work Experience on Employee Work Productivity
Based on the results of the analysis, it shows that there is a significant positive influence of work experience on employee work productivity, meaning that the more experience employees have at work, the higher the employee's work productivity, and vice versa, the more employees do not have work experience, the more employee work productivity decreases.
This shows that the experience a person gains will help in providing knowledge and skills that are appropriate to the work he is doing.A person doing this type of work repeatedly over a long period of time will make him become more familiar and skilled in carrying out the work.
The experience a person gains will help in providing knowledge and skills that are appropriate to the work he is doing.So, work experience is an important factor in carrying out a job, so that the goods or services produced have good quality and quantity.with good experience, employees will be more active in working and productivity will increase.
In contrast to the opinion of Snow & Lukman (2018); Kurniawan & Rimas (2021) show that work experience has no effect on employee productivity.This shows that there are still many employees who have little experience in their work.

The Influence of Job Satisfaction on Employee Work Productivity
Based on the results of the analysis, it shows that there is a significant positive influence of job satisfaction on employee work productivity, meaning that if employees feel satisfied with their work, employee work productivity will increase, and vice versa, if employees feel less satisfied with their work, employee work productivity will decrease, this shows that Job satisfaction felt by employees can increase work productivity, the more satisfied employees are, the more productive employees will be.Employees work according to their abilities and skills so they can increase work productivity.
The Z Tofu Factory has leaders who put fair pressure on all its employees, apart from that, there is good cooperation among employees so that there is self-satisfaction in each employee, employee job satisfaction is able to increase employee work productivity.This is in accordance with the opinion of Lilia et al (2020); Putri et al (2020); Slamet (2020); satisfaction has a positive effect on work productivity.Job satisfaction can encourage individuals to achieve more perfect and higher productivity (Sururin et al., 2020).The existence of satisfaction in individuals can increase work productivity if the organization provides a good reaction to the results that have been completed by employees (Adiwinata & Sutanto, 2014).This is different from the opinion of Hapsari, et al (2014) who stated that job satisfaction has no effect on employee productivity.

Conclusions
Based on the research results, it is clear that there is a significant positive influence of work experience on job satisfaction, meaning that the more employees have more experience at work, the more satisfied employees are in their work.There is a significant positive influence of work experience on employee work productivity, meaning that the more experience the employee has at work, the higher the employee's work productivity.There is a significant positive influence of job satisfaction on employee work productivity, meaning that if employees feel satisfied with their work, employee work productivity will increase.Job sufficient experience because they have worked for more than 5 years and are considered capable of completing work without needing to provide much direction, so they have satisfaction with the results of their work which has an impact on employee work productivity.
The limitation of this research is that the research sample of tofu factory employees is small in scale, so the sample used is very minimal, namely 45 respondents, so it cannot describe the experience, satisfaction and work productivity of employees.Suggestions for companies where it is known that satisfaction and experience with appropriate assessments and rewards for employees influence employee work productivity, therefore companies need to pay attention to employee satisfaction and work experience because they can increase employee work productivity.Future researchers should examine productivity in larger factories and with more production employees so as to produce more significant research results.
