The capacity of patient beds provided by Tarumajaya Hospital is 78 beds.
Several problems with the role of the internal inspection unit that occurred at Tarumajaya Hospital, among others, there were still employees/staff who did not understand the flow of the organizational structure and the division of job descriptions between sections, did not have a certificate in the implementation of the audit (audit). In addition, problems with the insurance claim management system are still related to the organizational flow. Where over time the BPJS patients are increasing. Likewise, the cases handled are increasingly complex with BPJS regulations that are always updated. In handling BPJS problems in the field, it requires the involvement of several work units, including Medical Records, Finance The Effect Of The Role Of Internal Audit Units On The Performance Of Insurance Claim Services And Management Systems With Fraud Prevention As Intervening Variables In Tarumajaya Hospital, Bekasi and doctors who provide services. Therefore, it is necessary to establish a special unit for handling BPJS patients which involves several related units. Tarumajaya Hospital has formed a Casemix Unit for the effectiveness of services for BPJS patients who are already increasing. Based on data obtained during 2021 where the submission of claims to BPJS Health showed a significant increase where in January 2021 there were 307 outpatient cases and in December 2021 there were 541 outpatient cases, where the largest percentage of pending cases occurred in April 2021 at 20% of 427 outpatient cases. As for this treatment, in January 2021 there were 374 inpatient cases and decreased in December 2021 as many as 254 inpatient cases, where the largest percentage of pending cases occurred in August 2021 at 43% of the 267 inpatient cases at the hospital. Tarumajaya Bekasi However, at this time, fraud is rampant in the development of the business world, including in the private and government sectors. Fraud or called fraud is a practice that can be carried out by parties who want to gain profits, both for individuals and groups that can harm other parties. Usually, fraud or fraud is carried out by people who have positions or authority over the assets of either the company or the state.
Fraud includes misstatement or omission of amounts or disclosures that are intentionally made with the aim of deceiving users, while the term asset misappropriation is often used to refer to theft by employees and other internal parties within an organization. Corruption is considered the most difficult type of fraud to prevent because of the cooperation carried out by parties inside and outside the organization for profit.
Hospitals, both government-owned and private, that serve BPJS Health participant patients, means that in the hospital funds will flow from the APBN/APBD. Therefore, the management of these funds must be accountable. The accountability for the management of funds originating from the APBN and APBD will be tested and examined by the Functional Audit Apparatus belonging to the Government and the State such as the Inspectorate General, Itwil Prop/District/City, BPKP, BPK and KPK if there are indications of fraud. In providing services to BPJS Health participants, it is not appropriate for hospitals to take actions that can be categorized as acts of fraud.
Based on the focus of the problem, the author wishes to examine in more depth the influence of the role of the internal audit unit on service performance and the insurance claim management system mediated by fraud prevention, which during its operation there were ups and downs in carrying out service activities, both in terms of patient visits and management/ medical personnel.

B. Data Collection Technique
Quantitative data collection method used in this study is to use the survey method, namely data collection techniques carried out by using questionnaires or questionnaires to reveal information or data from respondents. Questionnaire is a data collection technique that is done by giving a set of questions or written statements to respondents to answer.
This questionnaire was used because the data collection technique was carried out by giving questions or written statements to participants (Stewart et al., 2015). The instrument in this study is a closed questionnaire, namely a questionnaire that has provided alternative answers so that the respondents just have to choose. In this study, the measurement scale used is the Likert scale, which is the scale used to measure the opinion of a person or group of people about social phenomena, writing quantitative analysis using the following scores: • Score 1 for the answer Strongly Disagree (SD) • Score 2 for the answer Disagree (D) • Score 3 for the answer Agree (A) • Score 4 for the answer Strongly Agree (SA)

C. Data Analysis Technique
The data analysis technique used in this study was to analyze primary data obtained from distributing questionnaires at Tarumajaya Hospital which had been filled out by participants, in this case nurses. The type of research used by researchers in this study is descriptive analysis using explanatory causality quantitative analysis methods.

D. Univariate Analysis
Univariate analysis is an analysis carried out to analyze each variable from the results of the study. The purpose of univariate analysis is to see the frequency distribution.
Univariate analysis in this study uses the Three Box Method where the answer index analysis per variable aims to find out a descriptive picture of the The scoring technique used in this study is with a maximum score of 4 and a minimum of 1, then the calculation of the respondent's answer index is by the following formula: : is the frequency of respondents who answered 1 of the scores used in the list of questions in the questionnaire. F2 : is the frequency of respondents who answered 2 of the scores used in the list of questions in the questionnaire. F3 : is the frequency of respondents who answered 3 of the scores used in the list of questions in the questionnaire. F4 : is the frequency of respondents who answered 4 of the scores used in the list of questions in the questionnaire.

E. How to calculate index:
To get the tendency of respondents' answers to each variable, it will be based on the average score from the calculation results of the Three Box Method (Susanti & Rita, 2020),as follows: Upper limit of score range : (%Fx4)/4 = (40 x 4)/4 = 160/4 = 40 Lower limit of score range : (%Fx1)/4 = (40 x 1)/4 = 40/4 = 10 the number of respondents' answers does not start from number 0, but starts from numbers 10 to 40. The resulting index number shows a score between 40-10 with a range of 30. Using the three box method, the range of 30 is divided into 3 section, resulting in a range for each section of 10 which will be used as an interpretation of the index value as follows: 10 -20 : Bad 21 -30 : Good 31 -40 : Very Good

Results and Discussion A. Validity Test Results
The results of testing the validity of the question items on the questionnaire for each variable with criteria > 0.3 and Sig. Level < 0.05 (Sugiyono, 2022: 356), it indicates that all items have a greater correlation value. This means that all question items are valid.

B. Reliability Test Results
The reliability test is useful for determining whether the instrument, in this case the questionnaire, can be used more than once, at least by the same respondent, will produce consistent data. In other words, instrument reliability characterizes the level of consistency.
The reliability test used is the Cronbach Alpha method using the SPSS program. The Cronbach Alpha method is used to find the reliability of the instrument whose score is a range of several values or in the form of a scale. According to Sekaran in Priyatno (2013), decision making for reliability testing is as follows: • Cronbach's alpha < 0.60 = poor reliability • Cronbach's alpha 0.60 -0.79 = accepted reliability • Cronbach's alpha 0.8 or above = good reliability After being calculated with the help of the SPSS program, it can be seen that the reliability value (Cronbach's alpha) is as follows;

Figure 3 Reliability Test Results
From the table above, it can be seen that the Cronbach alpha value for the four variables is above 0.600. Because the value is greater than 0.600, the questionnaire measuring instrument is reliable or has met the reliability requirements.

C. Descriptive Analysis
Before entering the hypothesis testing stage, the researcher analyzed with descriptive analysis in which this analytical technique got an overview of the respondents' answers regarding the research variables used. This analysis was carried out using Index Analysis Techniques, to describe respondents' perceptions of the questions asked.
The answer index analysis per variable aims to find out a descriptive picture of the answers to the questions posed to the respondents. The scoring technique used in this study is with a maximum score of 4 and a minimum of 1, then the calculation of the respondent's answer index is by the following formula: Information: F1: the frequency of respondents who answered 1 of the scores used in the list of questions in the questionnaire. F2: the frequency of respondents who answered 2 of the scores used in the list of questions in the questionnaire. F3: the frequency of respondents who answered 3 of the scores used in the list of questions in the questionnaire. F4: the frequency of respondents who answered 4 of the scores used in the list of questions in the questionnaire.
To get the tendency of respondents' answers to each variable, it will be based on the average score from the calculation results of the Three Box Method (Susanti & Rita, 2020), as follows: Upper limit of score range: (%Fx4)/4 = (40 x 4)/4 = 160/4 = 40 Lower limit of score range: (%Fx1)/4 = (40 x 1)/4 = 40/4 = 10 According to Ferdinand (2016), the number of respondents' answers does not start from number 0, but starts from numbers 10 to 40. The resulting index number shows a score between 40-10 with a range of 30. Using the three box method, the range of 30 is divided into 3 section, resulting in a range for each section of 10 which will be used as an interpretation of the index value as follows: 10 -20: Bad 31 -30: Good 31 -40: Very Good

The structural model (Inne model) is a model that can prove from an interaction on causality that refers to the latent variable. In this study, structural samples can be assessed using the coefficient of determination test (R2) & multicollinearity test. The following is a path diagram display (path example) using PLS Bootstrapping calculations. The test results can be seen in Figure 9.  Based, the inner model is a structural model by describing the causal relationship between variables and those based on existing theories. The inner model will perform an analysis where the causal relationship between variables will be investigated.
In this section, several things that will be tested are VIF or multicollinearity, coefficient of determination or R-Square (R2), effect size (f2), predictive value (Q2), T-statistics, indirect effect.

L. Discussion of Research Results
Indirect influence of the role of the internal audit unit on service performance and insurance claims management system at Tarumajaya Hospital, Bekasi through fraud prevention From the results of SEMPLS analysis research, namely hypothesis H1 is accepted, there is an indirect influence on the role of the internal audit unit on service performance and insurance claims management system at Tarumajaya Hospital, Bekasi through fraud prevention. Fraud prevention can be done by activating internal audits. Active internal auditing is usually the most widely applied form of internal auditing. To deal with fraudulent procurement of goods in hospitals, systematic and integrated efforts are needed in investigative strategies and preventive strategies (Singleton & Singleton, 2010). The investigative strategy will indeed appear to be successful in eradicating corruption, but in the long term this strategy will encourage counter-productive conditions in development activities. This needs to be addressed by prioritizing preventive strategies. To implement this strategy, the internal control system must be implemented effectively. If the internal audit of a company is weak, the possibility of errors and fraud is very large. On the other hand, if the internal audit is strong, the possibility of errors and fraud can be minimized. Even if errors and fraud still occur, they can be identified quickly and corrective actions can be taken as early as possible.

M. The direct influence of the role of the internal examination unit on fraud prevention at Tarumajaya Hospital, Bekasi
From the results of the SEMPLS analysis research, namely hypothesis H2 is accepted, then there is a positive and significant direct influence on the role of the internal examination unit on fraud prevention at Tarumajaya Hospital, Bekasi. Audit is a condition that is built and created in a company that affects the effectiveness of internal audits. The inspection system is the dominant element that influences other elements in the SPI (Boynton, Johnson, & Kell, 2002) Where the positive direction of SPI towards fraud prevention means that the better the SPI, the greater the prevention of fraud that occurs. Likewise, if the SPI decreases, fraud prevention will decrease. The role of a weak internal audit unit in the government bureaucratic system can be an opportunity for officials and staff in the company, this is because the actions taken are not detected by anyone. On the other hand, if the role of the internal audit unit in the government's bureaucratic system improves, it will be difficult to commit fraud, because every activity carried out has been limited and supervised by the governance of the role of the internal audit unit. So, the more effective the level of internal inspection in a government bureaucratic system, the less opportunity for employees to commit fraud. This can support the theory put forward (Naufal & Aisyah, 2019) which states that the application of a good internal audit can prevent fraud which has been widely practiced so far.

N. The direct influence of the role of the internal examination unit on service performance at Tarumajaya Hospital, Bekasi
From the results of SEMPLS analysis research, namely hypothesis H3 is accepted, then there is a direct positive and significant influence on the role of the internal examination unit on service performance at Tarumajaya Hospital, Bekasi. Conceptually, a company or organization to achieve the goals to be achieved, employees must have awareness of the audit environment contained within the company. If the employee has understood the inspection environment in his work environment, it can be ascertained that the performance carried out by the employee can achieve the company's goals. which means that a good inspection environment can encourage increased ser (Dessler, 2015) The Effect Of The Role Of Internal Audit Units On The Performance Of Insurance Claim Services And Management Systems With Fraud Prevention As Intervening Variables In Tarumajaya Hospital, Bekasi

O. The direct influence of the role of the internal examination unit on the insurance claim management system at Tarumajaya Hospital, Bekasi
From the results of the SEMPLS analysis research, namely hypothesis H4 is accepted, then there is a positive and significant direct influence on the role of the internal examination unit on the insurance claim management system at Tarumajaya Hospital, Bekasi. (Romney & Steinbart, 2016) internal control (internal control) is an organizational plan and business methods used to safeguard assets, provide accurate and reliable information, encourage and improve the efficiency of the organization's operations, and encourage conformity with established policies. Internal control in insurance companies includes inspection, review, and evaluation of the adequacy and effectiveness of the company's internal control system, and the quality of work from the implementation of assigned responsibilities. In carrying out its duties, the internal control system has unrestricted access in examining company records, assets and resources, as well as matters deemed necessary and the internal control system in its implementation is obliged to maintain its security and confidentiality. In claim payment transactions, functions are established according to their respective duties. This is intended so that there is an internal check in the implementation of a transaction so that it is expected to minimize the possibility of fraud (Mary, Albert, & Byaruhanga, 2014).

P. The direct effect of fraud prevention on service performance at Tarumajaya Hospital, Bekasi
From the results of the SEMPLS analysis research, namely hypothesis H5 is accepted, then there is a positive and significant direct influence on fraud prevention on service performance at Tarumajaya Hospital, Bekasi. (Stamler, Marschdorf, & Possamai, 2014) states that: Prevention is based on the design of controls to reduce the risk of fraud against the corporation or criminal offenses on behalf of the corporation (in particular, bribery and money laundering) so that it does not occur. One indicator of a good local government financial performance is the achievement of an unqualified opinion on an audit of regional financial management. One of these opinions can be achieved if the procurement process for goods/services is carried out properly, in accordance with the laws and regulations and the role of the internal audit unit is adequate.

Q. The direct effect of fraud prevention on the insurance claim management system at Tarumajaya Hospital, Bekasi
From the results of the SEMPLS analysis research, namely hypothesis H6 is accepted, then there is a positive and significant direct influence on fraud prevention on the insurance claim management system at Tarumajaya Hospital, Bekasi. (Coenen, 2008) preventive control is focused on protecting company assets and information by stopping fraud. The National Health Insurance System is organized by the government as an effort to provide affordable and quality health services, including mental health services. In its implementation, it is suspected that there is a potential for fraud that can harm many parties, either directly or indirectly (Widiyati, Valdiansyah, Meidijati, & Hendra, 2021). The Corruption Eradication Commission has targeted the potential for fraud in the health sector to monitor potential fraud, because the potential losses caused are quite large. This is in accordance with research conducted by (Pramesti, Sunarsih, & Dewi, 2020) Internal control has a negative effect on preventing fraud in procurement of goods at the Badung Mangusada District Hospital. Organizational commitment has a positive effect on preventing fraud in procurement of goods at the Badung Mangusada District Hospital (Pramesti et al., 2020).

R. Research Findings
Based on the results of the research and discussion, it was found that the research findings where fraud prevention strengthens the influence of the role of the internal audit unit on service performance and insurance claims management system at Tarumajaya Hospital, Bekasi. In addition, there is an influence of the role of the internal audit unit on fraud prevention, service performance and insurance claims management system at Tarumajaya Hospital, Bekasi. These findings indicate that fraud prevention can be done by activating internal audits. Active internal auditing is usually the most widely applied form of internal auditing. To deal with fraudulent procurement of goods in hospitals, systematic and integrated efforts are needed in investigative strategies and preventive strategies (Singleton & Singleton, 2010).The investigative strategy will indeed appear to be successful in eradicating corruption, but in the long term this strategy will encourage counterproductive conditions in development activities. This needs to be addressed by prioritizing preventive strategies. To implement this strategy, the internal control system must be implemented effectively. If a company's internal audit is weak, the possibility of errors and fraud is very large. On the other hand, if the internal audit is strong, then the possibility of errors and fraud can be minimized. Even if errors and fraud still occur, they can be identified quickly and corrective actions can be taken as early as possible. Good hospital management will provide a reference or description of how the hospital is managed transparently, with independence, accountability, accountability and fairness so that financial performance at the hospital can be achieved in accordance with the vision and mission of the hospital that has been previously determined. However, this hope has not been fully felt, this is due to the inadequacy of the organization to create good management and the lack of high commitment from hospital managers as a result of various irregularities, fraud, smuggling and corruption. The phenomenon of fraud has become something common in hospitals. The high intensity of fraud, fraud, and embezzlement practices that occur in a public institution, with all its modes from the simple to the very sophisticated and complex, should awaken all parties to build commitment to the implementation of good governance consistently and widely at all levels because the existence of awareness and commitment will result in not achieving good financial performance at the hospital. Fraud can happen anywhere, can be done by anyone and has an impact on anyone who can harm all parties, either directly or indirectly, including those who commit the fraud.
Fraud in the business world can be done by unscrupulous employees both at the lower management level and at the upper management level. The fraud committed by these individuals is detrimental to stakeholders (owners, partners, doctors, employees). Fraud that occurs in the company will result in inefficiency in the company's operations.
The company's inefficiency due to fraud is the weak competitiveness of the company, decreased revenue, increased costs, decreased employee morale and threats to the company's survival.
Good internal audit allows management to be ready to face rapid economic changes, competition, shifting customer demand and fraud as well as restructuring for future advancements (Alao & Amoo, 2014). If a company's internal audit is weak, the possibility of errors and fraud is very large. On the other hand, if the internal audit is strong, the possibility of errors and fraud can be minimized.
This result is also in accordance with Coso's research, internal control is a process within the organization, which is designed to provide reasonable assurance regarding the achievement of objectives related to operations, reporting and compliance. Effective internal control reduces fraud prevention, so an ineffective control system tends to give someone the opportunity to commit fraud that will harm the company.
Even if errors and fraud still occur, they can be detected quickly and corrective actions can be taken as early as possible. As a health service entity to the community, we need an understanding of the internal examination that will be applied by employees at the hospital, where if this is implemented effectively it can prevent fraud. This is also explained by (Wells, 2017),that the implementation of internal audits on profit and non-profit companies can protect company assets from fraud and of course assist management in carrying out all its activities.
The creation of good governance in hospitals and having reliable organizational instruments to make hospitals survive as community services are demands that must be met (Chartier, 2014). This is very important, because the hospital is a responsibility center that is responsible for public health services so that the health received by the community can be affordable and of good quality.
