Introduction
Knowledge is seen as a valuable resource in today’s knowledge-based economy (Chang et al., 2015). This might happen because an organization’s readiness to adapt to global developments in terms of knowledge possession is highly influenced by high-quality resources within the company. Some experts have stated that numerous industries will continue to seek, maintain, and grow information, and the efficacy of knowledge management will be assessed by knowledge sharing behavior among corporate personnel (Heisig et al., 2016; Henttonen et al., 2016). Supported by Farooq and Vij (2019) which states that knowledge is considered a source of competitive advantage, and in the face of a dynamic business environment, the organization also needs to focus not only on efficient information processing but also on knowledge creation. If companies wish to gain a competitive advantage, they must manage their knowledge, and those with fascinating and distinctive expertise will have a better chance of entering a competitive industrial market (Mustika et al., 2020). The practice of successful knowledge sharing behavior in a company demonstrates that the company is well-versed in knowledge management (Heisig et al., 2016; Inkinen, 2016).
According to some studies, knowledge sharing behavior is one of the major stages in generating useful knowledge resources for a company’s quality-of-service delivery (Mafabi et al., 2017), and it may be sparked by a desire to share knowledge (Bai et al., 2019; Lin et al., 2018; Mirkovski et al., 2018; Sallam & Algammash, 2016). Intention to share knowledge in an organization refers to the willingness of employees to share knowledge with others that they have acquired or created (El Said, 2015). Meanwhile, the intention to share knowledge indicates how someone has a desire to share knowledge with others and the intention is due to a relationship or relationship interaction between the person and other individuals which is manifested in behavior (Fauzi, 2019). Furthermore, it is well understood that the desire to exchange knowledge is fueled by the presence of knowledge sharing self-efficacy (Zhao et al., 2016). Knowledge sharing self-efficacy is a behavioral control variable that may help people overcome issues in the learning environment connected to knowledge share (Ergün et al., 2018). Knowledge sharing self-efficacy is a marker of knowledge sharing behavior, and a lack of it might prevent knowledge sharing from occurring (Bao & Han, 2019; Zhang et al., 2017).
Another factor that can influence the occurrence of intention to share knowledge is enjoyment in helping others (Rahman & Reynolds, 2016; Wang et al., 2020). Enjoyment in helping others refers to behavior in presenting the perceived pleasure associated with helping others to share knowledge (Lai & Chen, 2011). Several previous studies have stated that enjoyment behavior has benefits for organizations (MacKenzie et al., 1993). Having enjoyment in helping others becomes a desire to improve the welfare of one or more people other than ourselves. According to previous study, the core of altruism is inspiring people to share their expertise with others because they participate in problem solving that is both hard and enjoyable (Okyere-Kwakye, 2011).
This study will examine the middle managers of Bank Syariah Mandiri in Indonesia who will be involved in the formation of PT Bank Syariah Indonesia Tbk. (BRIS) which is considered to have a significant multiplier effect on the national economy and economic growth by merging three Islamic banks which are members of the Association of State-Owned Banks (Himbara). Bank Syariah Mandiri (BSM) is known to be very aware that the process of distributing knowledge management must be managed in a structured and comprehensive manner, because it can support the dissemination of knowledge management, on the other hand, Bank Syariah Mandiri has carried out knowledge management (KM) activities since 2012. The implementation of knowledge management was marked by the kick off of the knowledge management program which was held on June 19, 2013. Bank Syariah Mandiri has a goal of implementing knowledge management, namely as an innovative and knowledge-based Islamic bank. From this basis, Bank Syariah Mandiri has been able to formulate a roadmap for the implementation of knowledge management with the following description.
The rapid development of Bank Syariah Mandiri in Indonesia has made it possible for the role of knowledge sharing self-efficacy, enjoyment in helping others, and the intention to share knowledge to drive the success of knowledge sharing behavior in middle managers. Knowledge sharing behavior at Bank Syariah Mandiri in Indonesia is an important behavior for the company’s success because with good knowledge sharing behavior, there can be an exchange of information both among employees and employees with consumers regarding various products and services provided by Bank Syariah Mandiri, or information. related to its function as a Sharia Bank. Knowledge sharing behavior at Bank Syariah Mandiri also needs to be considered carefully, because it will refer to the importance of knowledge to educate the public about the development of Islamic banks in the future. Previous literature has tried to use several theories to understand knowledge sharing behavior (Nguyen, 2020). Among them, the Theory of Planned Behavior is most often used to predict knowledge sharing behavior, because the theory has a solid theoretical framework, and has been considered the basic backbone for examining psychological factors that drive knowledge sharing behavior (Nguyen, 2020). Several previous studies have slightly discussed knowledge sharing among middle managers (Boulila Taktak, 2011; Misman & Ahmad, 2011; Othman & Mersni, 2014; Shahimi et al., 2006; Zoubi & Al-Khazali, 2007). Furthermore, knowledge sharing behavior is crucial for middle managers, according to certain research (Inkinen, 2016; Wang et al., 2016), since they are the driving force in the primary decision makers to foster a culture of knowledge sharing behavior. A middle manager is a person who works in a position between two levels of organizational leadership and two levels of professional personnel (Dutton & Ashford, 1993; Floyd & Wooldridge, 1997; Jafari et al., 2007). Janczak (2004) in his research discussed the dynamics and new roles of middle managers to create and share knowledge, so it can be concluded that middle managers have three behavioral roles, namely as analytical, intuitive, and pragmatic.
Literature Review
Theoretical Basis
Knowledge sharing self-efficacy
Bandura was the first to introduce the notion of self-efficacy. According to Bandura, self-efficacy is a belief in one’s ability to plan and carry out the activities necessary to control prospective occurrences (Anggarwati & Eliyana, 2015). Self-efficacy is a term used to describe people who believe they have the ability to achieve specific goals in a specific way (Syabarrudin et al., 2020). Self-efficacy is defined as the belief in one’s capacity to transmit information and the willingness to share it (both online and face-to-face) (Ergün et al., 2018). Furthermore, knowledge sharing self-efficacy is also recognized as a behavioral control variable that may assist the community in overcoming issues connected to knowledge exchange in the learning environment. In knowledge sharing, self-efficacy also refers to one’s confidence in one’s ability to provide meaningful information that might influence or enhance others’ desire to share their experiences and skills (Lai & Chen, 2011). Individuals with high knowledge sharing self-efficacy are more likely to accept any form of instruction since they believe they can achieve with the knowledge they already have.
Enjoyment in helping others
The act of expressing the pleasure associated with assisting others in sharing information is known as enjoyment in helping others (Lai & Chen, 2011). The source of joy in helping others is altruism, which is a kind of unconditional compassion or giving without expecting anything in return (Lin, 2007). One of the intrinsic incentives is the enjoyment of helping others, which refers to employees who are involved in solving tough or hard situations that are nevertheless connected to performance (Lin, 2007). Some people will find it enjoyable to share their knowledge in order to assist others without the expectation of receiving rewards in the future (Moghavvemi et al., 2017). In order to live a tranquil existence, one must enjoy assisting others in the social environment and cultivate human conduct without seeking monetary benefits or acclaim (Enelamah & Tran, 2020; Smith, 2011). According to Hsu and Lin (2008), pleasure is an important component in the process of adopting new work processes. As a result, it may be concluded that individuals only give aid and are glad to do so because they are organically driven to share their knowledge with others and enjoy helping others.
Intention to share knowledge
Many previous studies related to knowledge sharing adopted the theory of planning behavior (TPB) which refers to an intention, as useful for capturing motivational factors that influence behavior (Wang et al., 2014). Individuals who are willing to offer their skills or experience in order to assist their colleagues in the company are referred to as having the intention to share knowledge in the theory of planning behavior (TPB) literature (John, 2013; Liu et al., 2013; Papadopoulos et al., 2013). The preparedness to do an activity is indicated by a person’s intention (Fishbein & Ajzen, 2010), and intention is also an indication of how much a person tries or how much effort is made to display a desired behavior (Chang & Chuang, 2011; Chen & Hung, 2010; Hau et al., 2013; Liu et al., 2016). Intention to share knowledge can be done either through communication between individuals or through knowledge archives. Intention to share knowledge is known to be rarely measured in the knowledge management system literature, although it is considered the toughest challenge faced by organizations that want to increase the use of knowledge management systems (El Said, 2015). According to the study, one of the most significant concerns that may help colleagues with planning that emphasizes the work of the unit, and can also assist inspire individuals to utilize the system on a regular basis is the desire to share employee knowledge.
Knowledge sharing behavior
Knowledge sharing is seen as an integral aspect of knowledge management, which is in line with the belief that the effectiveness of knowledge management systems is dependent on knowledge sharing behavior (Rohman et al., 2020). Knowledge sharing is when members of a group act in a way that allows them to receive or provide knowledge, resources, experience, or something beneficial to or from other members (Mustika et al., 2020). Knowledge sharing behavior is also defined as group behavior activities that promote learning and improve their ability to achieve goals that involve the exchange of knowledge, skills, and expertise between employees across departments or organizations (Rohman et al., 2020). With the prospect of external benefits and reciprocity, knowledge sharing behavior will arise (Ergün et al., 2018). When group members think that knowledge sharing leads to mutual benefits or the preservation of reciprocal ties that can improve their job, knowledge sharing behavior is known to be steady and seamless. Knowledge sharing activity will pique the attention of group members since it may help them learn new things, increase interpersonal communication, get access to more relevant resources, increase work performance and problem-solving abilities, and promote professional capabilities (Tseng & Kuo, 2014).
Hypothesis Development
Knowledge sharing self-efficacy and intention to share knowledge
Knowledge sharing self-efficacy is known as an aspect that emphasizes more on the belief that the abilities possessed by individuals can be shared to do useful things related to whether a person is able or not able to complete the task at hand (Hsu et al., 2007). So it can be said that if someone has high self-efficacy, it will be easy to share with others. Furthermore, when employees believe that the rewards or the best results that will be generated through knowledge sharing are important, their intention to share knowledge will increase (Casimir et al., 2012). Individuals can establish their social status through knowledge sharing, and if the employee has high knowledge sharing self-efficacy, they can gain respect or a better image with this knowledge sharing (Chang et al., 2015). Then, they will also be more willing to share knowledge because they feel they have the appropriate abilities. According to Van Acker et al. (2014), people with high self-efficacy are more likely to engage in particular actions because they believe they have the capacity to do so, whereas knowledge sharing self-efficacy refers to someone’s trust in the ability to share information publicly (Mafabi et al., 2017). To have the confidence that comes with knowledge sharing self-efficacy, one must be convinced on the true knowledge that is worth sharing, as well as the ability to deliver that information well. As a result, the desire to impart knowledge will emerge. According to Mafabi et al. (2017) the intention to share knowledge requires an element of ability in an effort to carry out certain behaviors, and the intention to share knowledge is known to be influenced by self-efficacy as a control belief factor under the theory of planned behavior (Liao et al., 2013). Several previous studies have stated that there is a relationship between knowledge sharing self-efficacy and intention to share knowledge, so that if individuals have strong self-efficacy, they will have confidence in their abilities or expertise that can trigger the intention to share knowledge (Chen et al., 2012; Liu et al., 2013). Conversely, if the individual has weak or low self-efficacy, the individual will find it difficult and there is no desire to share knowledge. Research conducted (Arain et al., 2019; Bai et al., 2019) on middle managers in Islamic banking in Saudi Arabia showed that knowledge sharing self-efficacy has a positive influence on the intention to share knowledge, and it has also been proven that knowledge sharing self-efficacy has an influence on knowledge sharing with the intention to share which can be a strong mediation. Thus, this study hypothesizes that:
Enjoyment in helping others and intention to share knowledge
Because the process provides pleasure and happiness, enjoyment is misunderstood as the amount to which a person engages in the job, implying that it is a deciding factor of purpose (Moghavvemi et al., 2017). Another definition of enjoyment in helping others is the feeling of pleasure derived from assisting others via the contribution of information acquired because someone is naturally driven to do so. When people are provided suitable opportunities to engage with others through assisting others, the possibility of happiness in assisting others improves, and this may be regarded an opportunity that may be presented through knowledge sharing (Lin et al., 2020). So that someone who is working feels enjoyment in helping others, they will be triggered for the intention to share knowledge. During the knowledge sharing process, people who donate knowledge will feel sincere because they feel the pleasure gained from helping others. In addition, it is known that employees who enjoy helping others will be intrinsically motivated to contribute knowledge because the person is engaged in intellectual pursuits and solving fun challenging problems and because they still feel happy in helping others (Lin, 2007). Knowledge contributors who gain enjoyment in helping others will be more oriented and more inclined to intention to share knowledge. In turn, enjoyment in helping others can significantly affect the use of information systems by knowledge contributors with the intention to share knowledge. Empathy is part of enjoyment and the opposite of selfishness, which shows the individual’s ability to identify the thoughts and feelings of others, so that the intention to share will reduce or eliminate the stress experienced by individuals (Lin & Huang, 2013). Based on previous research (Hoseini et al., 2019; Tang et al., 2016) it has been concluded that enjoyment in helping others has a positive effect on intention to share knowledge. Similar research was conducted by Saide et al. (2019) and Tang et al. (2016) that enjoyment in helping others has a positive effect on intention to share knowledge. Thus, this study hypothesizes that:
Intention to share knowledge and knowledge sharing behavior
In companies that stress expertise, such as accounting, finance, or legal firms, the “personal” aspect plays a critical role (Hwang et al., 2018). Knowledge is incorporated in workers’ creative thinking in firms, and people’ desire to use knowledge systems is critical for the success of work systems based on the aim to share knowledge. Individuals are the source of knowledge obtained from organizations, hence focusing simply on the organizational perspective and ignoring the effect of “people” is insufficient from Suh and Wagner (2017). So, to make this happen, individuals should trigger themselves to have the intention to share knowledge in applying knowledge sharing behavior properly. It is known that the determinant of knowledge sharing behavior is in the form of intention, where the intention of the individual will have a great influence on a sharia banking because it does not only understand the field from a general perspective but also in terms of religious rules, so that the intention of middle managers has a good role The intention of the middle manager has a big role to realize the goals of knowledge sharing. Previous research has stated that the intention to share knowledge can be a predictor of knowledge sharing (Ryu et al., 2003), this is also the level of confidence of a person who will be involved in knowledge sharing behavior. Individuals who have a positive view of knowledge sharing activities will have a greater intention to carry out these activities (van den Hooff et al., 2012). As a predictor of knowledge sharing, the intention in a person can be increased by the organization to promote knowledge sharing behavior, so that there is a positive influence of intention to share on knowledge sharing behavior (Reychav & Weisberg, 2010). According to Lin and Lee (2004) intention to share knowledge has an effect on knowledge sharing behavior, this statement supports the results of research conducted by Jeon et al. (2011)) that intention to share knowledge has a positive effect on knowledge sharing behavior. Thus, this study hypothesizes that:
Knowledge sharing self-efficacy and knowledge sharing behavior
Self-efficacy, according to Olatokun and Nwafor (2012), might drive employees to share expertise with coworkers. Knowledge sharing self-efficacy in this situation indicates that employees are aware of their capacity to transfer information to others, and that others require that knowledge to complete particular activities in order to meet personal and organizational performance objectives (Islam et al., 2018). As a result, workers will be more conscientious about the value of their expertise in the growth of organizational performance, as well as proactive in sharing information with colleagues and actively gaining new information for future use and sharing. As a result, employees who have a high level of knowledge sharing self-efficacy are more willing to share their information. People will acquire confidence in what they can accomplish if their knowledge sharing self-efficacy rises, according to Jolaee et al. (2014), and they will believe that their talents can boost job efficiency, which will enhance productivity. As a consequence, it refers to a shift in information sharing behavior, and as a consequence, they will be more motivated to share their information with others. Previous study has indicated that the availability of knowledge sharing self-efficacy, which has been proved to have a major influence on information sharing behavior, is one strategy to drive employees to undertake information sharing activity (Amichai-Hamburger et al., 2016; Nguyen, 2020). The Theory of Planned Behavior shows the relationship between belief and behavior, which implies that behavior can be planned and is deliberative, which is the best function of the theory of planned behavior to predict behavior, especially in measuring individual behavioral intentions (Nguyen, 2020). Islamic banking requires individuals who have knowledge sharing self-efficacy which can be manifested in a person’s belief that their knowledge can help solve problems and share work-related ideas. Research that has been carried out by Bilginoğlu and Yozgat (2018), Pan and Zhang (2018), Safdar et al. (2021), and Zhang et al. (2016) showed that knowledge sharing self-efficacy has a positive effect on knowledge sharing behavior, this finding provides support that individuals with high self-efficacy tend to try hard in doing tasks and experience better positive emotions (Bandura, 1977). Thus, this study hypothesizes that:
Enjoyment in helping others and knowledge sharing behavior
Knowledge sharing behavior is defined as “the act of sharing task information and knowledge with others in order to assist them in creating new ideas, solving issues, or putting rules or procedures in place” (Lin et al., 2020). Because knowledge sharing entails a reciprocated exchange of knowledge and abilities (Moghavvemi et al., 2017), which is a sort of social exchange that allows individuals to engage and obtain external rewards such as mutual benefits and suitable connections (Moghavvemi et al., 2017). According to Islam et al. (2018) employees become motivated to show knowledge sharing behavior when they realize that knowledge sharing helps others to solve certain problems and work better. This is known to work well when the individual gives a feeling of pleasure which always motivates them to share their intellectual knowledge which is triggered by the feeling of enjoyment in helping others. The results of previous research conducted by Phung et al., 2019 and Whitener et al. (1998) have shown that enjoyment in helping others has a positive effect on knowledge sharing behavior. According to the study, when people are happy to share their knowledge in order to help others, they are more motivated to do so. The study also highlights altruism as a motivator for knowledge sharing behavior. The study also provides positive evidence that people who enjoy helping others will provide more useful knowledge, as previous research has suggested (Kankanhalli et al., 2005). Thus, this study hypothesizes that:
The above-mentioned hypotheses are conceptualized in the following framework (Figure 1).

Conceptual framework.
Research Method
Research Approach
This type of research includes research with a quantitative approach, which is carried out for testing theories by means of measurements that emphasize numerical data (on the variables studied and then analyzed using statistical test tools. This study uses a sample survey of a population with a questionnaire as a research tool in collecting data and analyzing respondents as research subjects. The data that has been obtained are tabulated and then processed using a statistical test of structural equation modeling (SEM – Amos). Measurement of knowledge sharing self-efficacy (X1), enjoyment in helping others (X2), intention to share knowledge (Y1) and knowledge sharing behavior (Y2) variables were measured using a Likert scale. Sekaran and Bougie (2016) explained that the Likert Scale was used to test how strong the responses of agreeing or disagreeing were given by respondents to the statements presented. The Linkert scale used in this study has five scales with 1 (strongly disagree) to 5 (strongly agree) which is described as follows, Strongly Agree (SS) = 5, Agree (S) = 4, Quite Agree, (CS) = 3, Disagree (TS) = 2, and Strongly Disagree (STS) = 1.
Measurement
Knowledge sharing self-efficacy
Knowledge sharing self-efficacy (X1) in this study is defined as the confidence of middle managers of Bank Syariah Mandiri in Indonesia in their ability to share knowledge related to activities, products, and services. The indicators of knowledge sharing self-efficacy (X1) in this study use an instrument developed by Lin et al. (2009).
Enjoyment in helping others
Enjoyment in helping others (X2) in this study is defined as the feeling of pleasure in the middle manager of Bank Syariah Mandiri in Indonesia in helping members or individuals related to knowledge. The indicators of enjoyment in helping others in this study use an instrument by Yan and Davison (2013).
Intention to share knowledge
Intention to share knowledge in this study is defined as the intention of middle managers of Bank Syariah Mandiri in Indonesia to share knowledge related to various activities, products and services at Bank Syariah Mandiri. The indicators of intention to share knowledge (Y1) in this study use an instrument by Chatzoglou and Vraimaki (2009).
Knowledge sharing behavior
Knowledge sharing behavior in this study is defined as the behavior of middle managers of Bank Syariah Mandiri in Indonesia in sharing their knowledge with their colleagues, both within divisions or in different divisions. The indicators of knowledge sharing behavior (Y2) in this study use an instrument by Lin and Lee (2004).
Data and Sample Collection Techniques
The participants in this study are middle managers from Bank Syariah Mandiri sub-branches in Indonesia who have held a supervisory position for at least 2 years, have never received a red card in the previous 2 years, have a thorough understanding of all Bank Syariah Mandiri products, and have participated in 1 year of training held every 3 months with no absence. The sampling technique of this research is using the census, meaning all members of the population are used as samples. In this study, an error tolerance level of 5% (0.05) was used, so the calculation using the Slovin formula for middle managers is as follows:
Based on the results of the calculation of the Slovin formula, a sample of 197 was obtained while the number of questionnaires collected was 297. Thus, the number of questionnaires collected has met the criteria of the Slovin formula and the assumptions in SEM (the assumption that SEM requires a sample of at least five times the number of indicator variables).
Data Analysis Techniques
The analytical technique used in this study is structural equation modeling (SEM) using the Amos 22 software program. Structural equation modeling can be a multivariate analysis technique that is able to analyze a series of multiple dependence relationships between latent variables simultaneously so that statistically it will produce more efficient results.
Data Analysis
The variable assessment was carried out by the middle manager of Bank Syariah Mandiri in Indonesia by answering various statements contained in the questionnaires that had been distributed. Common method bias can occur for several reasons, such as subjective perceptions of respondents, where each respondent has a different perception of the instrument used. This can also happen when respondents give incorrect answers to questionnaires, either over-reported or under-reported answers (Jordan & Troth, 2019). There are several procedural strategies that can be used to minimize common method bias, some of which were carried out by this study, namely by providing clear information about the objectives and benefits of research for respondents, providing technical instructions that facilitate and also guaranteeing the confidentiality of respondents’ identities (Jordan & Troth, 2019).
Respondent Demographics.
Table 1 shows four demographic variables that show the data as Gender, Age, Education, and Tribe of middle managers of Bank Syariah Mandiri in Indonesia.
Analysis Results Description.
Based on the table 2, it shows that the descriptions of respondents’ answers to all variables used, such as Knowledge Sharing Self-Efficacy, Enjoyment in Helping Others, Intention to Share Knowledge, and Knowledge Sharing Behavior have high categories.
Test Results of Measurement Model Knowledge Sharing Self-Efficacy and Enjoyment in Helping Others.
Table 3 and Figure 2 show that the exogenous measurement model of absolute fit Indices criteria with parameters RMR, GFI and incremental fit indices with parameters TLI and CFI in this study, provides a suitability index that is in accordance with the recommended limits. Meanwhile, there are other fit parameters which are not fit for the RMSEA and AGFI parameters. From the results of the measurement model in this study, it serves to ensure whether there are indicators that exceed the limit.
Test Results of Goodness of Fit Measurement Model Intention to Share Knowledge and Knowledge Sharing Behavior.
Based on Table 4 and Figure 3, the calculations for the endogenous measurement model of absolute fit indices criteria, namely RMR and incremental fit indices with CFI parameters in this study provide a suitability index that is in accordance with the recommended limits. While other fit parameters are moderate, namely GFI, TLI. Meanwhile, those who do not fit the RMSEA and AGFI parameters. From the various conformity indices in this study, it can be concluded that the measurement model on the proposed exogenous and endogenous constructs is fit or has a good suitability because there are two endogenous goodness of fit criteria and four goodness of fit criteria have been fit so there is no need for elimination. indicators of each—each variable.
Test Results of Contract Validity, AVE, and Reliability.
As shown in Table 5 and Figure 4, X1—Knowledge Sharing Self-Efficacy, X2—Enjoyment in Helping Others, Y1—Intention to Share Knowledge, and Y2—Knowledge Sharing Behavior. Based on the table, it is known that the results of the Validity and Reliability Test in this study have shown that all indicators used have met the research requirements, and it is stated that all indicators in this study affect the latent variables used. This can happen because the results of the Validity and Reliability Test have met the validity and reliability requirements for the study (Loading factor > .6, the average variance extracted value >.5, and the CR value > .7).
Model Fit Index on
Based on Table 6, there are four criteria for the model suitability index that are below the standard cut off value, namely RMSEA, RMR, TLI, CFI. Meanwhile, those that do not meet the model fit assumptions are the chi square index, GFI and AGFI. Based on the parsimony rule, if one or two of the fit criteria for the model have been met, the model has been declared fit. From the various conformity indices, it can be concluded that the structural model or structural model on the proposed endogenous construct fits or has a good fit. The overall fit can be assessed using the same criteria as the measurement model: using the χ2 value for the structural model and at least one absolute index and one incremental index (Hair et al., 2014, p. 587). While parsimony fit indices are not useful in assessing the fit of a single model, but are quite useful in comparing the fit of two models, one more complex than the other (Hair et al., 2014, p. 581). In this study, the sample size is 297 and the number of indicators is 19. Hair et al. (2014, p. 584), model with
• χ2: significant
• CFI or TLI above .90.

Conclusion
General Conclusion
The results show that knowledge sharing self-efficacy and enjoyment in helping others have positive and significant effect on intention to share knowledge; knowledge sharing self-efficacy, enjoyment in helping others and intention to share knowledge have positive and significant effect on knowledge sharing behavior; knowledge sharing self-efficacy and enjoyment in helping others have significant effect on knowledge sharing behavior mediated by intention to share knowledge. Based on the discussions, it can be concluded that the reality of internal and individual motivation, specifically the existence of knowledge sharing self-efficacy and enjoyment in assisting others, plays a significant role in knowledge sharing intention and behavior. According to Mafabi et al. (2017) knowledge sharing behavior is one of the key processes in building knowledge resources that are useful for the quality-of-service delivery in an organization. This is very much needed in achieving the company’s goals properly, and being able to create a company that is more effective and also able to influence the national economy and economic growth in Indonesia. The company has been proven to be able to influence knowledge sharing behavior well through knowledge sharing self-efficacy, enjoyment in helping others, and the intention to share knowledge among middle managers.
Implication
Theoretical implication
This study focuses on the knowledge sharing behavior of employees as an important resource for organizational success. The research model in this study enriches the literature by developing variables whose ultimate goal is to make employees achieve a competitive advantage so that they have the opportunity to enter the industry better and more usefully. This research model is strengthened by knowledge sharing self-efficacy which helps employees’ confidence in overcoming problems by exchanging knowledge in a learning environment. Then the role of enjoyment in helping others is as an intrinsic motivation which is also useful for finding solutions to challenging problems. The research was expanded by the intention to share knowledge which acts as a mediation. The presence of communication between individuals with knowledge will refer to a better intention to share knowledge for the willingness of employees to feel knowledge sharing self-efficacy and enjoyment in helping others which are important to realize positive knowledge sharing behavior.
Practical implication

Limitations and Suggestions
Several limitations of this study need to be addressed. First, this study only considers the responses of respondents who work at Bank Syariah Indonesia; therefore, it is recommended in future research to cover different populations such as in other banking contexts or other public services. Second, data were collected at the same time for this study. The use of further research can use longitudinal research to support associations developed through data collection at different times so that research results are more accurate. Third, the assessment in this study uses a quantitative approach. To get a broader answer, it is recommended to continue research with a qualitative approach. Fourth, this study does not use control variables such as company size, company age and type of industry as part of the study. So, it would be better if further research uses control variables to enrich the findings. Moreover, examination of different mediating variables should be considered in future studies to enrich knowledge in this area.
