Introduction
Basically, every activity in the company will not be separated from the risk.Every organizational activity has uncertainty that is identical to risk, including fraud (Karyono, 2013:1).Fraud can be termed as fraud that contains meaning and irregularities and illegal acts, which is done intentionally for a specific purpose, such as deceiving or giving misleading images to other parties.People can do this both from within and from outside the organization.Fraud is designed to take advantage of opportunities that are not honest, which directly or indirectly harm other parties (Karyono, 2013:4).In Indonesia alone, fraud cases still frequently occur in various companies, both private companies or state-owned/regional companies.The 2016 Global Association of Certified Fraud Examiners (ACFE) results show that each year an average of 5% of organizational revenues in Indonesia are victims of fraud (ACFE Indonesian Chapter, 2017).
Fraud prevention is eliminating opportunities or opportunities to commit fraud by developing and implementing risk management (specifically fraud risk management), internal control and honest corporate governance (Priantara, 2013:184).One way to minimize fraud in the company is important for companies to improve the effectiveness of the internal audit.This internal audit helps the organization achieve its goals by taking a systematic and disciplined approach to assess and improve risk management, control, and governance processes (Redding et al., 2013:2).The internal audit function is a function of free appraisal within an organization to review or study and assess the company's activities to provide suggestions to management so that their responsibilities can be carried out effectively (Tugiman, 2014:11).Internal auditors as the most appropriate agent to realize internal control, risk management and good corporate governance, which will undoubtedly add value to resources and the company (Kumaat, 2014:35).
Risks faced by the company include integrity risk, namely the risk of fraud by management or company employees, illegal actions, or other irregularities that can reduce the good name/reputation of the company in the business world or can reduce the company's ability to manage internal audit is an autonomous activity, objective viewpoints, and consultation meant to add value and enhance organizational works.This internal audit helps the organization achieve its objectives by taking a methodical and disciplined appearance to evaluate and enhance the effectiveness of risk management, control, and governance processes (Redding et al., 2013:2).Internal audits intend to help companies perform adequate controls by evaluating their effectiveness and efficiency and encourage continuous enhancement (Sawyer et al., 2014:55).The risk of fraud requires the internal auditor to develop preventive measures to prevent fraud (Amrizal, 2014:11).
In addition to internal auditing, one factor of fraud in the company is caused by weak internal control (ACFE, 2017).Internal control is a process composed, performed, and controlled by those charged with governance, management, and other employees to provide sufficient confidence regarding the fulfillment of an entity's objectives correlating to the reliability of financial statements, efficiency and effectiveness of operations, and compliance with laws (Agoes, 2017:162).
The paramount prevention of fraud is to establish an internal control system in every movement of the organization.In order to effectively inhibit fraud, internal control must be competent in the design of its control structure and sound practices in its implementation (Karyono, 2013:47).The relationship between internal control and fraud problems in a company is very related.Fraud is always a difficult issue.A good internal control system aims to ensure that organizational activities are effective and efficient (Tugiman, 2014:12).A comprehensive internal control system, implemented thoroughly and regularly monitoring the activities of an organization, is an important step to safeguard and detect the risk of loss caused by fraud in the financial sector.Internal control is very important in detecting financial fraud that is at the risk of harming the company (Susanto, 2014:93).Implementation of internal control can at least reduce management collusion regarding fraud (Natasya et al., 2017).
Information quoted from the article shows that PT Pos Indonesia still commits corruption in connection with the procurement of Portable Data Terminal (PDT), namely regarding corruption cases related to the cost of sending Social Protection Cards (KPS) and incompatible specifications of the equipment provided by the agreement in the procurement contract.The case of making the country suffer losses due to the procurement of funds obtained from the Ministry of State-Owned Enterprises (BUMN) (Rahman, 2016).Other information shows that there is still allegations of corruption committed by PT Pos Indonesia related to the provision of tantiem or bonuses to the directors and commissioners of PT Pos Indonesia in 2017 by selling assets in the form of shares in Mandiri Taspen Pos Bank.The granting of bonuses when companies suffer losses can be categorized as detrimental to the state leading to corruption (Movanita, 2017).Therefore we need an activity to prevent fraud.
Other information quoted from the 2017 national Kompas article, Boyamin Saiman, as the Coordinator of the Indonesian Anti-Corruption Society, stated that PT Pos Indonesia had suspected corruption.Boyamin Saiman suspected that there were irregularities in giving bonuses to the directors and commissioners of PT Pos Indonesia in 2017, even though the company was at a loss.PT Pos Indonesia is suspected of attempting to manipulate the books so that it appears as if it is experiencing profits by selling assets in the form of shares in Bank Mandiri Taspen Pos.PT Pos Indonesia gave Rp. 5,359,000,000 to the company's Directors and Commissioners in 2017.In the same year, PT Pos Indonesia was declared to be losing money based on the company's 2017 balance sheet.Boyamin Saiman also stated that giving bonuses when the company loses money can be categorized as causing losses to the state leading to criminal acts of corruption with a total loss of Rp 5,359,000,000.Moreover, the bonus was given after selling assets in the form of shares in Bank Mantap amounting to Rp 324.61 billion.Of this amount, IDR 200 billion was included as revenue.In addition, Boyamin Saiman considered the sales figures too cheap.Along with the report, Boyamin attached evidence in the form of PT Pos Indonesia's profit and loss report to a list of tantiem payments to company directors and commissioners from the Attorney General's Office (Movanita, 2017).
Several previous studies relating to this study have been conducted by Maliawan et al. (2017).The results of his research indicate that internal audit and the effectiveness of internal control affect the prevention of fraud.Research conducted by Suginam (2017) shows that internal audit and internal control have an effect on fraud prevention.In addition, research conducted by Wijaya and Nugraha (2017), the results of his study showed that internal control and internal audit affect fraud.Based on the results above, the researcher is interested in further researching the effect of internal audit and internal control on fraud prevention at PT Pos Indonesia (Persero) Bandung.

Internal audit
Internal auditing is an activity designed to increase value and improve organizational performance.This activity can help achieve an organization's goals by conducting a methodical and disciplined approach to evaluating and improving risk management, control, and governance processes through activities in the form of independent and objective consultation and assurance (Redding et al., 2013:2).The internal audit function is a function of free appraisal within an organization to review or study and assess the company's activities to provide suggestions to management so that their responsibilities can be carried out effectively (Tugiman, 2014:11).Internal audit aims to assist all company leaders (management) in carrying out their responsibilities by analyzing assessments, suggestions, and comments on the activities they inspect (Agoes, 2017:222).The scope of the internal inspection must include testing and evaluation of the competence and effectiveness of the organization's internal control system and the quality of the implementation of the responsibilities given, including the reliability of the information, compliance with legal policies and procedures, protection of assets, use of resources economically and efficiently and achieving goals (Tugiman, 2014:17).According to The Institute of Internal Auditors (IIA) in Redding et al.

Internal control
Internal control is a method meant to provide appropriate assurance regarding the achievement of objectives related to progress, reporting, and compliance.This process is influenced by the board of directors, management, and other entity personnel (Redding et al., 2013:6).According to Tuanakotta (2015:94) states that the objectives of internal control are as follows: 1. Strategic objectives, with the main objectives that support the entity's mission.
2. The purpose of financial reporting, so that financial statements are free from material misstatements in a timely and effective manner 3. Operational objectives, whereby controls secure the entity's operations, known as operational controls 4. The purpose of compliance with laws and statutory provisions.Internal commands appropriate for an audit are controls for financial reporting, particularly those relating to the entity's purpose making economic reports for external purposes.
According to the Committee of Sponsoring Organization of the Treadway Commission (COSO) in Redding et al. (2013:9)  The most important aspect of internal control is personal.Because competent and trusted personnel can control internal control, including building adequate controls, methods for appointing, evaluating, training, promoting, and compensating personnel.While an incompetent person will only break the system, there is much control in place.

Risk assessment
The company goals' achievement is potentially threatened by some risks faced by the company itself.Therefore, every risk, including the internal and external risks must be assessed.According to COSO, all company is facing various kind of risks originating from within and outside.Further, the risk is the likelihood of an event emerging and affecting the objectives' or the patients' achievement.

Control activities
Control activities are procedures, steps, and policies used to ensure the crucial action to solve, prevent or deal with risks to help the company achieve the company goals.Control activities consist of some actions done by the company management, boards, and other parties.This action is done to increase the company's level of success in reaching their goal and reducing any potential risk.Therefore, the control activities must be carried out at every level in the company.In addition to separating duties or obligations, there are several control activities implemented in a sound internal control system, namely: Documentation (comprehensive and strict) b.Independent verification along with reconciliation c.Control activities through physical access d.Controlling activities application (input; process; output) e. Review of performance and follow-up f.Authorization (approval) g.Access to control activities

Information and communication
In order to run a business effectively, every relevant, timely, and accurate information should be available for access by everyone in the organization at every level.Meanwhile, the highquality information should be spread and communicated appropriately.The information must be available for certain parties to support operational achievement, compliance, as well as for reporting purpose.In addition, good communication should be applied widely in terms of achievement, the responsibilities of each individual or group, and other important matters

Monitoring
Monitoring activities are the internal control related to the quality assessment.This activity is also defined as the ongoing or periodic activity to determine the controlling process as expected by the management.The information for the monitoring process is gained from many sources, such as the reports from an internal auditor, the studies of existing internal control, and the feedback from operational personnel.Implementing a multilevel approach will increase the effectiveness of the monitoring activities.The first monitoring level is including the daily activities done by the company's management.The second level is a separate evaluation for internal control done by the management to ensure the identification and resolution of deficiencies in a timely manner.Then, the third level of monitoring activity is the independent assessment, for instance, doing the internal audit function in order to ensure controlling effectiveness from the accuracy and reliability of the management's assessment.Afterward, it can be concluded that the monitoring activities occur in every internal control's components.

Fraud prevention
The word fraud contains meaning as well as irregularities and illegal acts, which are done intentionally for certain purposes such as deceive or providing a misleading image to other parties, whether good people do it from the outside or within the company.Fraud is designed to take advantage of opportunities that are not honest, which directly or indirectly harm other parties (Karyono, 2013:4).According to Arens et al. (2014:340) states that there are three factors a person commits fraud known as a fraud triangle, namely as follows: 1. Pressure Economic pressure is one of the factors that drives a person to commit acts of fraud.This factor comes from the individual of the offender where he feels that the pressures of life are so heavy forcing the offender to commit fraud for his personal gain.This usually happens because the welfare guarantee offered by the company or organization where he works is lacking or a completely luxurious lifestyle so that the perpetrator constantly feels inadequate.However, the pressure can also come from the environment in which he works, such as an unpleasant work environment.Employees feel they are not treated fairly.There is an unfair employee recruitment process.

Opportunity
The opportunity factor comes from the outside of any individual, namely from the organization as victims of fraud.There are chances or possibilities to commit fraud in all position.With his position, the offender feels he has the opportunity to take advantage.
Coupled with a control system from an inadequate organization.

Rationalization
The perpetrator feels he has strong reasons for justifying what he is doing and influencing the other party to approve what he is doing.
Fraud prevention eliminates opportunities to commit fraud by developing and implementing risk management (especially fraud risk management), internal control and honest corporate governance (Priantara, 2013:184).According to Priantara (2013:196) states that fraud that may occur must be prevented, among others, by the following methods: 1. Build a good internal control structure The more a company develops, the task of management to control the company's operations becomes increasingly heavy.So that the goals set by top management can be achieved, the security of company assets is guaranteed, so that the management needs to establish a good as well as effective internal control structure to prevent fraud can be carried out efficiently and effectively.

Making the control activities effective
Making effective control activities can be done by reviewing employee performance, processing information to become information that has accuracy and completeness, physical control of assets by adequate safeguarding facilities that are protected from access to assets, and segregation of duties is useful to give responsibilities to people different in order to avoid double duty and authority.

Improve organizational culture
Improving organizational culture is done by implementing the principles of the GCG (Good Corporate Governance) principle that are interrelated to encourage the organization resources' performance to work efficiently.

Making the internal audit function effective
Although the internal auditor cannot guarantee that fraud will not occur, he must use the proficiency of his position carefully so that fraud detection is expected and be able to provide useful suggestions to management to prevent fraud.

Relationship of internal audit on fraud prevention
One way to prevent and minimize fraud is to improve internal audit.Internal audits aim to assist the organizations in implementing the significant controls by examining the level of efficiency and effctiveness and encouraging constant improvement.(Sawyer et al., 2014:55).Internal auditors as the most appropriate agent to realize internal control, risk management and good corporate governance, which will certainly add value to resources and the company (Kumaat, 2014:35).
Risks faced by the company include integrity risk, namely the risk of fraud by management or company employees, illegal actions, or other irregularities that can reduce the good name/reputation of the company in the business world or can reduce the company's ability to maintain internal audit is a neutral or independent activity, impartial beliefs.Consultation is designed for improving the organizational work by adding some values to it.This internal audit assists the organization to reach their goals by taking a disciplined and systematic approach for improving and evaluating the risk management's control, level of effectiveness, and governance processes (Redding et al, 2013: 2).The task of minimizing and preventing fraud belongs to the internal auditors.These tasks are done by testing the effectiveness and adequacy of the internal controlling system and evaluating the studied potential risks' extention (KOPAI, 2004: 65).The existence of these risks requires internal auditors to develop preventive actions that can minimize fraud (Amrizal, 2014).According to the preceded description, the hypotheses formed are as follows: H1: Internal audit influences on fraud prevention.

Relationship of internal control on fraud prevention
Establishing an internal control system for every organization activity is the main point of preventing fraud.Further, implementing this internal control system should be reliable in its control structure design and sound practices to achieve effective fraud prevention (Karyono, 2013:47).The internal control and fraud problems in a company have a close and related relationship.Fraud is always a difficult issue.A good internal control system aims to ensure that organizational activities are effective and efficient (Tugiman, 2014:12).
A comprehensive internal control system implemented thoroughly and regularly monitoring the activities of an organization is an important step to safeguard and detect the risk of losses caused by fraud in the financial sector.Internal control is very important in detecting financial fraud that is at the risk of harming the company (Susanto, 2014:93).Implementation of internal control can at least reduce management collusion regarding fraud (Natasya et al., 2017).Fraud prevention strategies are related to controlling the drivers of fraud by creating conditions that can encourage fraud prevention efforts, so to implement this strategy, internal control must be implemented effectively.Good internal control is a widely used method by many parties to prevent fraud.Therefore it can be stated that a good internal control application will improve fraud prevention as well (Wulandari and Nuryatno, 2018).Based on the description above, the hypotheses formed are as follows: H2: Internal control influences on fraud prevention

Research methodology
This research was using the quantitative research type for analysis.The research methodology used in this study was the verification research method.91 employees at PT Pos Indonesia (Persero), Bandung City, were taken as the population in this study.Then, this study was also used the nonprobability sampling with the method of saturated sampling.Below will be presented the number of employees from each division at PT Pos Indonesia (Persero) Bandung, as follows: The types and data source used in this research are the primary data.Data collection methods used in this study are through a questionnaire that is distributed directly to research respondents.The independent variable in this study is internal audit and internal control, while fraud prevention is the dependent variable.The data analysis method applied in this research is multivariate analysis.The multivariate analysis applied in this research is the analysis of multiple linear regression using SPSS Vers.25.00 software.

Validity test
Validity is a measuring tool used to obtain data.The result of the study is valid if both of the data collected and the data that occurs of the study have a similarity.(Sugiyono, 2017: 348).Validity can be measured using the product moments Pearson correlation coefficient.According to Sugiyono (2017: 348) the formula for the correlation coefficient for product moments Pearson is as follows: The sum total score of all Yi items X = Total score of each item Xi In this study, the item validity was measured by comparing the calculated r value and r table; that is, the calculated r value was obtained from the results in the correlated item-total correlation column.If the calculated r value> r table, then the item or question or indicator is declared valid (Ghozali, 2016: 53).

Reliability test
Reliability test is done by doing equivalent, test-retest (stability), and a combination of both.Internally, Analyzing the consistency of the items on the instrument with specific techniques is the way to test the reliability of the instrument.The researcher can carry reliability testing with the Cronbach alpha technique for interval/essay data types (Sugiyono 2017: 356).According to Sugiyono (2017: 356) the formula for calculating Cronbach's alpha is as follows: − + (Sugiyono, 2017:356) Information: k = The number of manifest variables that make up the latent variable r = Average correlation between manifest variables Questionnaire items are said to be reliable (feasible) if Cronbach's alpha based on standardized items> 0.70 (Ghozali, 2016: 53).Y = 0,287 + 0,417 X1 + 0,503 X1 + e

Results
The equation above shows that internal audit and internal control have a positive direction of influence, meaning that the internal audit and control and the prevention of fraud are higher, and vice versa.Source: SPSS Output 25 Table 9 above shows that the influence of internal audits on fraud prevention is 30.2%.Besides, the influence of internal control on fraud prevention was 38.6%.

Discussions

The research results on fraud prevention show the total value of the actual score of 5248, the ideal score of 7735, the percentage value of 67.85% and the mean score of 3.39 which are categorized as quite good.This shows that the fraud prevention of PT Pos Indonesia (Persero) Bandung is in the fairly good category.
The results showed that the internal audit influences fraud prevention.The amount of influence of internal audit in contributing to the effect of fraud prevention is 30.2%.The theoretical basis supports this study's results in the previous discussion, which states that one way to prevent and minimize fraud is to increase internal audit implementation.The internal audit aims to help organizations to have implemented adequate controls.Moreover, it can be done by evaluating effectiveness and efficiency and encouraging continuous improvement.(Sawyer et al., 2014: 55).Internal auditors are the most appropriate agents to realize internal control, risk management, and good corporate governance, which will add value to resources and the company (Kumaat, 2014: 35).

Conclusion
The results show that internal audit affects fraud prevention.The amount of influence of internal audit in contributing influence to the prevention of fraud of 30.2%.The theoretical basis supports the results of this study in the previous discussion, which states that one way to prevent and minimize fraud is to improve internal audit implementation.Internal audits aim to implement adequate controls by checking their efficiency and effectiveness and encourage continuous improvement.(Sawyer et al., 2014:55).Internal auditors as the most appropriate agent to realize internal control, risk management and good corporate governance, which will undoubtedly add value to resources and the company (Kumaat, 2014:35).
Risks faced by the company include integrity risk, namely the risk of fraud by management or company employees, illegal actions, or other irregularities that can reduce the good name/reputation of the company in the business world or reduce the company's ability to maintain internal audit.It actually is a straight belief, separated activity and consultation purposed to give value and boost organizational activities.This internal audit aims to achieve its goals by taking a systematic and disciplined approach to check and lift the effectiveness of risk management, control, and governance processes.(Redding et al., 2013:2).Internal auditors help to prevent and minimize fraud by testing the effectiveness and adequacy of the internal control system by evaluating the extent of potential risks to be identified.(KOPAI, 2004:65).The existence of these risks requires internal auditors to develop preventive measures that can minimize fraud (Amrizal, 2014:11).This study's results are in parallel with the results of previous studies by Maliawan et al. (2017), Suginam (2017), Wijaya and Nugraha (2017), Gusnardi (2011), Festi (2014), Monisola (2013), Ait Novatiani andJulaeha (2013).The results of his research indicate that internal audit affects fraud prevention.
The results also show that internal control affects the prevention of fraud.The amount of influence of internal control in contributing influence to the prevention of fraud of 38.6%.The theoretical basis supports this study's results in the previous discussion, which states that in order for the company objectives set by top management to be achieved, the security of company assets is guaranteed and operations can be carried out efficiently and effectively.Moreover, it also needs to make an effective and well-structured internal control to prevent fraud (Priantara, 2013: 196).The primary way to prevent fraud is by making an internal control system in the organization's activities.Internal control to effectively prevent fraud must be in a decent design of its control structure and sound simple in its application.(Karyono, 2013: 47).The relationship between internal control and fraud problems in a company is very related.Fraud is always a difficult issue.A good internal control system aims to ensure that organizational activities are effective and efficient (Tugiman, 2014: 12).A comprehensive internal control system implemented thoroughly and regularly monitoring the activities of an organization is an important step to safeguard and detect the risk of losses caused by fraud in the financial sector.Internal control is very important in detecting financial fraud that is at the risk of harming the company (Susanto, 2014: 93).
Implementation of internal control can at least reduce management collusion regarding fraud (Natasya et al., 2017).Fraud prevention strategies are related to controlling the drivers of fraud by creating conditions that can encourage fraud prevention efforts, so to implement this strategy, internal control must be implemented effectively.Good internal control is a widely used method by many parties to prevent fraud.It can be said that more appropriate the application of internal control, the prevention of fraud in the organization will increase (Wulandari and Nuryatno, 2018).This study's results are in parallel with the results of previous studies by Maliawan et al. (2017), Suginam (2017), Wijaya and Nugraha (2017), Gusnardi (2011), Zarlis (2018), Saleh (2016).The results of his research indicate that internal control influences the prevention of fraud.
The following conclusions are obtained based on the results and discussions: 1.The research results on internal audit showed that the implementation of internal audit shown by PT Pos Indonesia (Persero) Bandung was included in both categories.2. The implementation of internal control shown by PT Pos Indonesia (Persero) Bandung is included in the quite good category.Fraud prevention of PT Pos Indonesia (Persero) Bandung is categorized quite good.3.This study's result also showed that internal audit and internal control influence fraud prevention.The higher the application of internal audit and internal control, the higher the prevention of fraud.
