ABSTRACT Purpose: This study examines how work motivation and work discipline influence employee loyalty in the Regional Public Drinking Water Company (PDAM) of Bandar Lampung City, with job satisfaction positioned as a mediating mechanism. Design/methodology/approach: A quantitative explanatory design was applied. Primary data were collected through a structured questionnaire administered to 82 permanent employees who had worked for at least one year. The model was assessed using partial least squares structural equation modeling (PLS-SEM). Measurement quality was evaluated through indicator loadings, average variance extracted, and composite reliability, while the structural model was evaluated using path coefficients, t-statistics, p-values, and coefficients of determination. Findings: Work discipline had the strongest positive effect on job satisfaction ( = 614, p < . , followed by work motivation ( = 0. 322, p = . Job satisfaction significantly predicted employee loyalty ( = 0. 517, p < . Work motivation also had a direct positive effect on employee loyalty ( = 309, p = . , whereas work discipline did not directly predict employee loyalty ( = 0. 142, p = . The coefficient pattern indicates that job satisfaction is a central mechanism linking motivation and discipline to Originality/value: The study contributes to public-sector human resource management by showing that employee loyalty in a municipal water utility depends not only on rule compliance and motivation, but also on whether these conditions translate into felt job satisfaction.

INTRODUCTION Human resources remain a core strategic asset for organizations, particularly in public service institutions where service continuity depends on the quality, reliability, and commitment of employees. Public water utilities operate under strong public expectations: they must deliver essential services consistently while also maintaining internal organizational effectiveness. In this context, employee loyalty becomes a critical human resource outcome because loyal employees are more likely to remain with the organization, maintain service quality, and support institutional objectives over time. The Regional Public Drinking Water Company (PDAM) of Bandar Lampung City represents a public utility setting in which work processes require discipline, coordination, responsibility, and responsiveness to community needs. However, human resource management in such organizations does not always operate optimally. Differences in employee motivation, uneven levels of work discipline, and varying experiences of job Volume 7. Number 1, 2026 https://ijble. com/index. php/journal/index satisfaction may affect the degree to which employees remain attached to and willing to contribute to the organization. Work motivation is commonly understood as the internal and external energy that directs work behavior toward organizational goals. Self-determination theory explains that motivation is not merely a matter of intensity, but also of quality, because employees are more likely to sustain work effort when they perceive autonomy, competence, and relatedness in the workplace (Deci et al. , 2017. Ryan & Deci, 2. In organizational practice, motivated employees tend to show stronger work enthusiasm, willingness to improve, and persistence in achieving expected performance outcomes. Work discipline is equally important in public service organizations. It reflects employees' willingness to comply with rules, meet attendance and punctuality expectations, complete assigned tasks, and assume responsibility for organizational standards (Sutrisno. In highly regulated service institutions, discipline may create procedural order and reduce uncertainty in daily operations. Nevertheless, discipline alone may not be sufficient to build loyalty unless employees also experience their work positively. Job satisfaction is a central psychological response to work. It refers to employees' evaluation of their job, including the suitability of tasks, perceived rewards, supervisory relationships, and the comfort of the work environment (Locke, 1976. Spector, 1. Satisfied employees are more likely to express favorable attitudes toward their organization, while dissatisfaction is often associated with weaker attachment and stronger withdrawal tendencies (Tett & Meyer, 1. The present study addresses a practical and theoretical gap in the human resource management of municipal utilities. Although motivation, discipline, and satisfaction are widely studied in private-sector settings, fewer empirical studies examine how these factors jointly explain loyalty in local public service organizations. This study therefore investigates the direct effects of work motivation and work discipline on job satisfaction and employee loyalty, as well as the mediating role of job satisfaction in the PDAM Bandar Lampung Literature Review and Hypothesis Development Work motivation and job satisfaction Work motivation refers to the forces that encourage employees to initiate, direct, and sustain work-related behavior. In the human resource management literature, motivation is linked to employees' willingness to exert effort, improve performance, and pursue organizational objectives (Hasibuan, 2. From a self-determination perspective, motivation becomes more sustainable when the workplace supports autonomy, competence, and social relatedness (Deci et al. , 2. Employees who are motivated to improve and achieve their best results are therefore more likely to experience their work as meaningful and satisfying. Based on this reasoning, the first hypothesis is proposed: H1. Work motivation has a positive effect on job satisfaction. Work discipline and job satisfaction Work discipline describes employee adherence to organizational rules, punctuality, task completion, and responsibility. Discipline creates regularity and predictability in work processes, which can reduce interpersonal and operational friction. In a public utility, discipline is especially relevant because work delays and non-compliance may directly affect service quality. Employees who work in an orderly and rule-consistent system may perceive Volume 7. Number 1, 2026 https://ijble. com/index. php/journal/index stronger role clarity and fairness, which can increase job satisfaction. Accordingly, the second hypothesis is proposed: H2. Work discipline has a positive effect on job satisfaction. Job satisfaction and employee loyalty Employee loyalty reflects an employee's willingness to remain in the organization, contribute to organizational goals, maintain the organization's reputation, and develop a sense of belonging. Although loyalty is conceptually distinct from organizational commitment, it overlaps with positive attachment and retention-oriented attitudes. Prior work on job attitudes indicates that satisfaction and commitment are important predictors of employees' withdrawal or retention-related decisions (Meyer et al. , 2002. Tett & Meyer. Thus, satisfied employees are expected to show greater loyalty because their work experience provides psychological reasons to remain and contribute. Therefore, the third hypothesis is proposed: H3. Job satisfaction has a positive effect on employee loyalty. Direct effects of motivation and discipline on loyalty Motivation may directly foster loyalty because employees who possess high work enthusiasm and personal growth orientation are more likely to identify with organizational In contrast, the direct relationship between discipline and loyalty is less Discipline may ensure compliance and task completion, but it does not necessarily generate emotional attachment unless employees interpret the disciplined work system as supportive, fair, and satisfying. The following hypotheses are proposed: H4. Work motivation has a positive effect on employee loyalty. H5. Work discipline has a positive effect on employee loyalty. Mediating role of job satisfaction Job satisfaction may function as an intervening mechanism that translates motivation and discipline into loyalty. When employees are motivated, they may feel more competent and purposeful, which increases satisfaction and, in turn, loyalty. Similarly, disciplined work systems may increase satisfaction by providing order and responsibility, and satisfaction may then strengthen loyalty. Thus, job satisfaction is expected to explain how motivation and discipline become linked to employee loyalty. The mediation hypotheses are formulated as follows: H6. Job satisfaction mediates the relationship between work motivation and employee loyalty. H7. Job satisfaction mediates the relationship between work discipline and employee loyalty. Figure 1. Structural model with standardized path coefficients. Volume 7. Number 1, 2026 https://ijble. com/index. php/journal/index METHOD This study used a quantitative explanatory design because it aimed to test causalpredictive relationships among latent constructs. The empirical setting was the Regional Public Drinking Water Company (PDAM) of Bandar Lampung City. Indonesia. The organization was selected because it provides essential public services and relies heavily on employee reliability, discipline, and service-oriented performance. The unit of analysis was the individual employee. The study focused on four constructs: work motivation and work discipline as exogenous variables, job satisfaction as a mediating variable, and employee loyalty as the final endogenous variable. The population consisted of employees working at PDAM Bandar Lampung City. Because not all employees could be reached within the study period, purposive sampling was applied. Respondents were selected using two criteria: they were permanent employees and had worked for at least one year. These criteria were used to ensure that respondents had sufficient experience to evaluate working conditions and organizational Primary data were collected using a structured questionnaire distributed to 82 Secondary information was obtained from organizational documents, reports, and literature relevant to the study. The questionnaire used a five-point Likert scale ranging from strongly disagree to strongly agree. All constructs were operationalized as reflective constructs. The indicators were retained from the source questionnaire and aligned conceptually with established human resource management literature. Table 1 presents the operational definitions and indicators used in the study. Table 1.

Data were analyzed using partial least squares structural equation modeling (PLSSEM). PLS-SEM was selected because the study was prediction-oriented and involved a relatively modest sample size. Following recommended PLS-SEM reporting procedures, the measurement model was assessed using standardized outer loadings, average variance extracted (AVE), and composite reliability (CR). Indicator loadings above . AVE values 50, and CR values above . 70 were interpreted as evidence of adequate convergent validity and internal consistency reliability (Hair et al. , 2019, 2. Volume 7. Number 1, 2026 https://ijble. com/index. php/journal/index The structural model was evaluated using standardized path coefficients, t-statistics, p-values, and RA values. Because PLS-SEM does not rely on the same assumptions as ordinary least squares regression, the analysis emphasized measurement-model and structural-model quality rather than classical regression assumption tests. Specific indirect effects were estimated from the product of path coefficients and interpreted using a Sobeltype approximation because the available output reported path coefficients and standard errors but did not provide bootstrapped indirect-effect statistics. For a final journal submission, the bootstrapped specific indirect-effect table from SmartPLS should be inserted if available. RESULTS AND DISCUSSION Respondent profile The sample consisted of 82 employees of PDAM Bandar Lampung City. The source manuscript indicates that male employees dominated the respondent profile, most respondents were in the productive age range, and many had relatively long work tenure. This profile suggests that respondents had sufficient organizational exposure to assess motivation, discipline, job satisfaction, and loyalty. For journal submission, detailed demographic frequencies and percentages should be inserted when the original respondent table is available. Measurement model assessment All retained indicators produced standardized outer loadings above . 80, exceeding the commonly recommended minimum of . This indicates that each item contributed strongly to its respective construct. Table 2 reports the item-level loadings. Table 2.

Discussion The results show that work motivation and work discipline are both important antecedents of job satisfaction among PDAM Bandar Lampung employees. However, the effect of work discipline was stronger than that of work motivation. This finding is theoretically meaningful for a public utility context. In organizations responsible for essential services, punctuality, compliance with rules, task completion, and responsibility are not merely administrative expectations. they structure daily work routines and create a more predictable work environment. Employees may therefore experience greater satisfaction when discipline supports operational clarity and fairness. Work motivation also had a significant positive effect on job satisfaction. Employees who show stronger work ethic, achievement orientation, and willingness to develop are more likely to interpret their work positively. This aligns with motivational theory, particularly the view that employees are more satisfied when work supports purposeful effort and personal growth (Deci et al. , 2017. Ryan & Deci, 2. Job satisfaction had a strong positive effect on employee loyalty. This result supports the broader job-attitudes literature, which argues that favorable evaluations of work strengthen employees' attachment to the organization and reduce withdrawal tendencies (Meyer et al. , 2002. Tett & Meyer, 1. In the PDAM context, satisfied employees are more likely to stay, contribute, develop a sense of belonging, and protect the company's The direct path from work motivation to employee loyalty was significant, suggesting that motivation can independently strengthen employees' willingness to remain and In contrast, work discipline did not directly predict loyalty. This indicates that rule compliance and punctuality, although important, do not automatically produce loyalty unless they are accompanied by job satisfaction. Discipline appears to become meaningful for loyalty when employees experience disciplined work arrangements as satisfying rather than merely coercive. The mediation results reinforce this interpretation. Job satisfaction partially mediated the effect of work motivation on loyalty and fully transmitted the effect of work discipline on Thus, the main managerial lesson is that motivation and discipline should not be managed as isolated administrative targets. They should be embedded in a broader human resource system that makes employees feel valued, recognized, comfortable, and aligned with their work. Theoretical and Practical Implications Theoretical implications This study contributes to human resource management literature by clarifying the role of job satisfaction as a psychological mechanism linking motivation and discipline to loyalty in a municipal public utility. The findings support a process-oriented view: employee loyalty Volume 7. Number 1, 2026 https://ijble. com/index. php/journal/index is not produced solely by administrative discipline or motivational encouragement, but by the extent to which those conditions create satisfying work experiences. The study also suggests that work discipline may have different theoretical implications depending on the outcome examined. Discipline strongly predicts satisfaction, but it does not directly predict loyalty. This distinction is useful because it prevents discipline from being interpreted only as a direct loyalty-building tool. Practical implications For PDAM Bandar Lampung City, the findings indicate that strengthening employee loyalty requires an integrated human resource strategy. First, management should maintain clear work rules and punctuality standards, because discipline strongly predicts job Second, discipline should be implemented consistently and fairly so that employees perceive it as a supportive system rather than punitive control. Third, motivational practices should emphasize recognition, growth opportunities, performance feedback, and meaningful involvement in organizational goals. Management should also monitor job satisfaction as an early indicator of loyalty. Because job satisfaction is the strongest direct predictor of loyalty in the model, improvement programs should focus on the quality of work assignments, fairness of rewards, supervisory support, recognition, and workplace comfort. Public utility organizations that improve these aspects may be better positioned to retain employees and sustain service performance. Limitations and Future Research This study has several limitations. First, the sample consisted of 82 employees from one public water utility, which limits the generalizability of the findings to other regions or public organizations. Future research should use larger and more diverse samples across multiple municipal utilities. Second, the study used a cross-sectional questionnaire design. Although the structural model estimates relationships among variables, causal inference should be interpreted cautiously. Longitudinal designs would help assess whether motivation and discipline predict changes in satisfaction and loyalty over time. Third, the source conceptual discussion recognized organizational commitment and the work environment as theoretically important constructs. However, the empirical output available for this revision did not include measurement indicators, loadings. RA values, or structural paths for organizational commitment or work environment. Therefore, the present article reports only the variables supported by available empirical results. Future studies should explicitly measure organizational commitment and work environment to test a more comprehensive model. Fourth, the mediation results in this revised manuscript were calculated using a Sobel-type approximation based on the reported path coefficients and standard errors. Future submission should replace this approximation with bootstrapped specific indirect effects exported directly from SmartPLS. CONCLUSION This study examined the effects of work motivation and work discipline on employee loyalty through job satisfaction among employees of the Regional Public Drinking Water Company (PDAM) of Bandar Lampung City. The findings indicate that both work motivation Volume 7. Number 1, 2026 https://ijble. com/index. php/journal/index and work discipline significantly improve job satisfaction, with work discipline showing the stronger effect. Job satisfaction, in turn, significantly increases employee loyalty. Work motivation also directly increases employee loyalty, while work discipline does not directly influence loyalty. These results indicate that discipline is important, but it contributes to loyalty mainly when it strengthens job satisfaction. Overall, job satisfaction is the central mechanism through which motivation and discipline become translated into employee loyalty. For public utilities, employee loyalty should therefore be developed not only through rules and motivational encouragement, but also through work conditions that allow employees to feel satisfied, valued, and committed to service quality.
