INTRODUCTION
Making a profit and being the best at satisfying customer needs are just two of the company's many objectives.Companies must continue to be productive in creating goods of the highest and most durable quality based on these two factors.since of this, employee work productivity is crucial since it allows the business to meet customer needs with sustainable products, which will enable it to meet its profit target.Many factors can influence the level of employee work productivity, including an employee's work discipline, work motivation or encouragement, as well as support from the work environment where work activities take place every day.Employees who have a supportive work environment, are motivated and have good discipline, the company's productivity targets will be achieved.
Productivity at work is the capacity to generate optimal or even maximal output while maximizing the use of resources and infrastructure that are available.Productivity is defined as the ratio of input (labor, capital, raw materials, or raw materials and equipment) to output (goods or services).In the process of increasing productivity, managers, technicians and employees must all produce more output (rupiah value, production units and service units) from each unit of input.They must produce more output for every hour of labor used, for every dollar of capital investment, for every unit of energy consumed in production.Thus, the relationship between a manufacturing system's input and output can be understood as productivity.
PT. Tirta Sari Surya is a company founded in Rengat District, Indragiri Hulu Regency.This company is a company that operates in the industrial sector, especially the production of crumb rubber.Work productivity figures at PT. Tirta Sari Surya is not optimal, meaning the results realized are not in accordance with the targets that have been set.For more details, see the following table:

LITERATURE REVIEW Employee Productivity
Productivity comes from the word production, the word production is often used in the sense of making something.Production is the conversion of materials from sources into desired results for consumers.These results can be in the form of goods or services.The term production is often associated with the term productivity, even though production facilities are active.
Productivity is a measure of efficiency in carrying out a task or activity to achieve the desired results.In general, productivity refers to the extent to which the resources used (such as time, labor, and equipment) can produce the desired output or results.Productivity is often measured by comparing the amount of output produced with the amount of resources used.(Swastha, 2017:281) Several factors that can influence productivity include work process efficiency, time management, innovation in technology or work methods, workforce motivation, and management effectiveness.Productivity is not just about doing more work, but also about doing work in a smarter and more efficient way (Sutrisno, 2017: 102).
Key aspects of productivity involve the comparison between input and output.Input involves resources such as time, labor, money, and raw materials, while output is the final result or product of the activity.Increasing productivity is often considered a positive goal because it can lead to economic growth, better efficiency, and increased welfare.
In general, work productivity is defined as the relationship between real and physical results (goods or services) and actual intentions.Productivity is also defined as the level of efficiency in producing goods and services, productivity reveals how to utilize resources well in producing goods.Keep in mind that productivity is not just about the amount of work done, but also about how that work is done better and more efficiently.By increasing productivity, organizations and individuals can achieve more using existing resources]

Work Environment
The work environment is a group of physical, social, and psychological factors that shape the context in which a person works.This includes everything from the physical office space and equipment used to the dynamics of employee relationships and company culture.The work environment can have a significant impact on worker well-being, productivity and satisfaction.
A good work environment can improve employees' psychological and physical well-being, as well as increase productivity and workforce retention.On the other hand, an unsupportive work environment can cause stress, dissatisfaction, and even decreased performance.(Afandi, 2018:65) Company management often strives to create a work environment that is inclusive, collaborative, and supports employee personal development.This can include initiatives such as training, wellbeing programs and flexible working policies.By creating a positive environment, companies can increase employee happiness and productivity, which in turn can contribute to the company's long-term success.(Danang, 2012:71) The work environment is the totality of tools and materials encountered, the surrounding environment where a person works, the way they work, and the work arrangements both individually and in groups.(Sedarmayanti, 2011:2) So it can be concluded that the work environment is the conditions around the worker when the worker carries out his duties, where these conditions have an influence on the worker when carrying out his work.If the work environment is conducive, employees will work optimally.On the other hand, an inadequate work environment can reduce employee work productivity.

Motivation
Motivation plays an important role in understanding how a person behaves at work.With motivation, it is hoped that an employee will have high work enthusiasm.Employees who have a strong drive to work harder than before.Motivation that comes from within a person varies depending on the strength of the drive from within the person himself, this is often called internal factors.Motivation can also be obtained from outside a person, giving rise to feelings of wanting to be better in the future, this is often called external factors.According to Armstrong (Torang, 2013:57), motivation comes from 2 (two) dimensions.Apart from that, Usman (Torang, 2013: 58) explains that motivation is a psychological process that encourages someone to do something.
According to Suyanto (Ratnaningsih, 2012:23) Work motivation refers to the strength or drive that encourages a person to do work or achieve certain goals in the context of the work environment.Motivation is an internal or external factor that motivates individuals to act, work hard, and achieve achievements.Having strong motivation can increase productivity, performance and job satisfaction.Motivation is an internal or external factor that motivates individuals to act, work hard, and achieve achievements.Having strong motivation can increase productivity, performance and job satisfaction.(Iskandar,2019)

Research Site
To complete this proposal, the author took the research location at PT. Tirta Sari Surya, Indragiri Hulu Regency.

Population and Sample
In this study, researchers took a sample of 373 employees.The procedure used to determine the research sample is and the Slovin formula above, so the sample from this study is as follows:

b. Data
The data in this research is in the form of questionnaire data filled in directly by village officials.

Research Instrument
The instrument used in this research was a questionnaire prepared using a Likert scale with several options, namely: Strongly Agree (SS), Agree (S), Somewhat Agree (CS), Disagree (TS), and Strongly Disagree (STS).
In this research, the author carried out frequency distribution analysis and mean (average value) to provide an overview of respondents' tendencies in conducting research.response.In carrying out this analysis, the author formulated a reference interval on which to draw conclusions.

b. Trust Test
An index called reliability indicates how much a measurement device may be depended upon or trusted.When measuring the same symptom twice or more using the same measuring tool, reliability is the degree to which the results stay constant.Reliability measurements in this study used the Cronbach's Alpha method.An instrument is said to be reliable if Cronbach's alpha is more than 0.60.This calculation will be carried out with the help of the IBM SPSS Statistics 21 computer program.If a measuring device produces consistent results when used repeatedly at various periods, it is considered trustworthy.
Before analyzing data using multiple linear regression, the analysis requirements are first tested, namely: 1. Normality Test To check whether the data coming from the population is normally distributed or not.The normality test is guided by the Kolmogorov Smirnov test, namely: a.If the significance value is <0.05 (95% confidence level) then the distribution is not normal.b.If significance value > 0.05 (95% confidence level) is normally distributed.

Linearity Test
This test is used to see whether the model specifications used are correct or not.Should the functions used in Empirical Studies be linear, quadratic, or public?With the linearity test, information will be obtained whether the empirical model should be quadratic linear or general.To determine whether or not there is a linear relationship between the predictor variable and the dependent variable, it can be seen by comparing the significant value of Deviation from Linearity with the significance used, where if the significant value is greater than significant then there is a linear relationship between the independent variable and the dependent variable.

Model Feasibility Test (F Test)
The F test is often called the goodness of fit test.According to Ghozali (2016), the model feasibility test is to test whether there is a significant influence on the overall regression model.Decision making in the model feasibility test (goodness of fit) is as follows: a.
If the statistical value of goodness of fit > 0.05, then Ho is rejected, which means there is a significant difference between the model and the observed values so that the research model is not appropriate.
b.If the goodness of fit statistical value is <0.05 then Ho is accepted, which means the model is able to predict the observation value so that the research model is correct.

Path Analysis
A statistical analysis technique called path analysis enables the provision of a quantitative interpretation or interpretation of the correlation among several variables in the model.In addition to testing the size of the contribution shown by the route coefficient on each path diagram of the causal relationship between variables, path analysis is used to ascertain the direct and indirect influence between a number of factors.
The following is the structural equation of path analysis: Structural equation: Y1 = PY1X1X1 + PY2X2X2 + €1

Multiple Correlation Coefficient (R)
Objective this method is an analysis used to discuss the strength of the relationship between the variables studied.This figure shows the relationship between variables which are given the notation "R".

Coefficient of Determination (R2)
The purpose of this method is the analysis used to discuss the percentage influence of the variables studied

Hypothesis Test (t test)
The t test (t-test) is used to prove whether or not the influence of each independent variable is significant on the dependent variable partially.For this reason, the decision criteria quoted from Ghozali (2011:85) are used, namely:  When tcount > Qtable then Hi is accepted, meaning there is a significant influence from this variableindependent of the dependent variable. When tcount < Ttable then Hi is rejected, meaning there is no significant influenceindependent variable to the dependent variable.

Analysis of the Influence of the Work Environment on Employee Productivity
Instrument Test 1. Validity Test To determine whether an instrument is valid or not, it must meet the following requirements: 1.If r is calculated > r table with a significance level of 0.05 then the instrument is said to be valid.2. If r is calculated < r table with a significance level of 0.05 then the instrument is said to be invalid By using the Cronbach's Alpha formula, good work environment reliability (X) calculation results were obtained, namely 0.890, greater than 0.312, so it can be concluded that the work environment (X) measurement tool in this research is reliable.

Reliability Statistics
Cronbach's Alpha N Items ,857 5 Source: SPSS Version 24 Processing Data By using the Cronbach's Alpha formula, reliability calculation results were obtainedwork productivity(Y) at a good level of confidence, namely 0.857 is greater than 0.312 so it can be concluded that the measuring instrument forwork productivity(Y) in this study is reliable.

Test the Classical Assumptions 1. Normality test
From the data above, it can be seen that the PP Plot in the output shows the points scattered around the diagonal line, so it was decided that the regression model had a normal distribution.To estimate normality it can be determined usingKolmogorov-Smirnov test

Autocorrelation Test Model Summary b
From the Durbin Watson table, look at column k (the number of independent variables) and row n so that it becomes 2 and 91.The dU value of the table is 1.6000 so the limit is between dU and 4-dU (1.6000 and 2.259).Looking at the output in the Model Summary box, it can be seen that the calculated Durbin-Watson value is 2.298 so it is decided that there is no autocorrelation in the regression model.The regression model is free from multicollinearity problems if the Tolerance value is more than 0.10 and the VIF value is less than 10, which means there is no correlation between independent variable.Look at the output in the Coefficient box.All Tolerance values are above 0.10 and VIF values are less than 10, so it is concluded that the regression model is free from multicollinearity.

Heteroscedasticity Test
Looking at the scatterplot in the output, you can see that the points are spread between -2 and 1 and do not form a particular pattern, so it can be concluded that the regeneration model is heteroscedastic or not.Based on SPSS version 24 data, it is known that the constant ( ) of 6.954 and the coefficient X (β1) of 0.513 with the path analysis equation Y = 0.551 ( ) = The constant is 6.954 and if the independent variable is considered zero (0), it means work productivity is 6.954 if X (work environment) is equal to 0 (zero).β1 = the work environment regression coefficient is 0.51Figure 3 shows that for every one unit increase in the work environment, there will be an increase in work productivity of 0.513.Β2

Regression Analysis (Descriptive
= The work motivation regression coefficient of 0.164 indicates that for every one unit improvement in the work environment, there will be an increase in work productivity of 0.164.

The Impact of the Work Environment on Work Productivity
Research and Discussion according to PT. Tirta Sari Surya Indragiri Hulu Regency, This refers to the conditions and elements around the workplace, including physical, social and psychological aspects that influence employee experience and productivity.The work environment has a significant role in shaping people's lives and experiences and plays a key role in environmental science and related fields.This implies that employee job satisfaction will rise in direct proportion to the quality of the work environment.On the other hand, employee job satisfaction will decline in an unfavorable work environment.Therefore, special attention is needed to ensure that the employee's workplace is well maintained.

The Impact of the Work Environment on Motivation
The workplace has an important role in increasing motivation.A favorable environment can increase well-being and motivation, while an unsupportive environment can result in stress and decreased productivity.Every company will definitely provide facilities that make its employees comfortable at work so they can improve performance and achieve company goals.The importance of a supportive work environment is not only for employee well-being but also for the overall success of the organization.Organizations that pay attention to these factors tend to have more satisfied, engaged, and productive employees.The work environment has something to do with motivation.Research conducted by PT.Tirta Sari Surya, Indragiri Hulu Regency stated that the work environment has a positive and significant effect on motivation, meaning that every time the work environment improves, motivation will increase.

The influence of the work environment on employee work productivity through motivation
The workplace is a very important factor in increasing employee work productivity.Companies certainly have their own standards that must be met to ensure employee comfort at work.An inadequate work environment will have a negative impact on employee work productivity, so that employees will feel uncomfortable at work and ultimately will not feel satisfied at work.This dissatisfaction will cause a lack of work enthusiasm so that employee work productivity will be disrupted in completing their work.If reduced worker productivity is not addressed right away, it will affect the company's ability to meet its objectives.Employee job satisfaction can be well attained and performance will improve if the organization creates a very comfortable work environment for its employees.

CONCLUSION
A. Conclusion 1. Work environment at PT. Tirta Sari is classified as good and this is proven by the work environment having a positive effect on employee work productivity.2. There is a positive influence between the work environment on motivation.
3. There is a positive influence between the work environment on productivity through work motivation.
B. Suggestion 1.To further increase work productivity, it is hoped that the work environment is adequate for use by employees.2. Leaders are expected to be able to motivate their employees more at work so that employees feel more enthusiastic when working, for example by providing rewards when employees achieve a work goal.
3. The lowest indicator in the employee work productivity variable is self-development.To further increase employee work productivity, companies can provide access to all employees to develop themselves so that all employees have a contribution to activities in the company.
