Published: January 15, 2026 Abstract: This quantitative investigation examines the impact of workplace conditions and motivation on tutor performance, incorporating job satisfaction as a mediating factor. Data was gathered via questionnaires distributed to tutors across 10 Training and Course Institutions (LKP) in Kampung Inggris. Pare. Kediri. Indonesia. From a total population of 185 tutors, 165 completed surveys were returned and analyzed. Researchers employed a non-probability sampling strategy, specifically judgmental purposive sampling. Analysis was conducted using Partial Least Squares Structural Equation Modeling (PLS-SEM). The results demonstrate statistically significant positive effects: both the work environment and work motivation directly enhance tutor performance and also have a positive influence on job satisfaction. Furthermore, job satisfaction itself exerts a significant positive effect on performance. Crucially, mediation analysis confirms that job satisfaction partially mediates the relationship between the work environment and work motivation, and both of these factors influence tutor performance. These findings offer valuable insights for institutional enhancement strategies.

However. Indonesia ranks alarmingly low . th out of 113 nation. in the 2023 English Proficiency Index (EF Reports, 2. , signaling an urgent need for skill enhancement. Non-formal education institutions (Lembaga Kursus dan Pelatihan/LKP) have emerged as vital solutions, with Kampung Inggris Pare serving as IndonesiaAos largest language-learning hub, attracting over 40,000 learners annually (Mukhroji et al. , 2. This ecosystem generates significant economic value, circulating Rp 3. 9Ae11. 2 billion monthly and empowering local communities through tourism, homestays, and small businesses (Mualifah & Roekminiati, 2018. Wawan & Surjono, 2. Despite this success. LKPs in Kampung Inggris face systemic challenges: 60% fail to meet IndonesiaAos Eight National Standards for Non-Formal Education, including tutor qualifications and infrastructure (Alexandro, 2. Tutor performance is further hindered by dual roles, background-job mismatches, low compensation, and declining professionalism, as evidenced by tardiness, absenteeism, and reduced teaching enthusiasm (Fahriyansyah & Muhammad, 2. Prior studies reveal inconsistent findings on the impact of work environment and motivation on performance. While Khabri et al . and Kusumastuti et al . (Kusumastuti et al. , 2. confirm positive effects. Anggraini . and Citriadin et al . report non-significant results. Similarly, motivationAos influence varies across contexts (Gusriani et al. , 2022. Wahyudi et al. Arifin et al. / Work Environment. Motivation, and Tutor Performance: Job Satisfaction as Mediator in Language Course Institutions IJNI: International Journal of Nusantara Islam Vol. No. : 247-260 Crucially, job satisfactionAos mediating role remains underexplored in non-formal education, particularly in unique settings like Kampung Inggris, where tutors navigate multicultural classrooms, flexible curricula, and seasonal workloads. This gap is compounded by the absence of studies examining how environment and motivation jointly shape tutor performance through satisfaction, a nexus vital for sustaining LKP competitiveness. This study addresses these gaps by analyzing: . the direct effects of work environment and motivation on tutor performance. their indirect effects mediated by job satisfaction. practical strategies for LKPs. Using quantitative data from 165 tutors across 10 institutions, we test a novel mediation model integrating Self-Determination Theory . ntrinsic/extrinsic motivatio. and Job Characteristics Theory . nvironment-satisfaction linkag. Theoretically, this resolves contradictions in prior literature while extending human resource frameworks to non-formal Practically, findings will equip LKPs with evidence-based policies to enhance tutor retention, pedagogical innovation, and institutional resilience. This research offers tripartite contributions. Theoretically, it validates job satisfaction as a full mediator in non-formal education, reconciling inconsistent past findings through structural equation modeling (SEM-PLS). For practitioners, it provides actionable levers: optimizing physical environments . , noise-controlled classroom. , fostering intrinsic motivation . , professional autonom. , and redesigning reward systems. Policy-wise, it advocates integrating IndonesiaAos National Education Standards into LKP accreditation to elevate tutor welfare and program quality.

Thus, 30. 2% of the variability in tutor performance is influenced by other factors outside of this model. The slightly lower adjusted R-square value . indicates that this model also takes into account the number of variables used, and still shows that the model has a good fit. For the job satisfaction variable, the R-square value is 0. 461, with an adjusted R-square of These results indicate that the model accounts for approximately 46. 1% of the observed variance in job satisfaction, implying that 53. 9% of its variability stems from factors beyond the current model's scope. While lower than the variance explained for tutor performance, the adjusted RA value of 0. 454 nevertheless demonstrates adequate explanatory power for the job satisfaction To assess the model's capacity to anticipate the dependent variable, predictive relevance is Below is the calculation for the QA value ycE 2 = 1 Oe .

Bootstrapping Test Results Based on the R 2 and Q2 testing above, it shows that the model in this study is robust, so hypothesis testing can be carried out. The path coefficient in the structural model needs to be statistically significant, which can be determined through the bootstrapping method. This involves examining the model parameters and the corresponding t-statistic values reported in the bootstrapping analysis. To assess significance, the critical t-value . 96 at = 0. is compared to the calculated t-statistic derived from the bootstrapping results. If the calculated t-statistic exceeds the critical value, the hypothesis is considered valid. The path analysis confirms significant positive relationships across all hypothesized direct First, work environment exerts a substantial influence on tutor performance ( = 0. t = 3. 683, p < 0. , validating H1, while also significantly enhancing job satisfaction ( = 229, t = 3. 409, p = 0. , supporting H2. Similarly, work motivation directly boosts tutor performance ( = 0. 278, t = 3. 123, p = 0. , confirming H3, and demonstrates an even stronger impact on job satisfaction ( = 0. 537, t = 8. 529, p < 0. , affirming H4.

All t-statistics exceed the critical threshold of 1. 96 ( = 0. confirming statistical significance. These robust coefficients collectively verify that both environmental conditions and motivational drivers directly elevate job satisfaction and performance outcomes, while job satisfaction itself functions as a critical performance accelerator within Kampung InggrisAos educational framework. Discussion The results confirm that job satisfaction significantly mediates the relationship between work environment and tutor performance ( = 0. 108, t = 2. 729, p = 0. , supporting H6. This partial mediation indicates that while work environment directly enhances performance, its impact is concurrently channeled through job satisfactionAivalidating the dual-path influence.

Both mediation pathways demonstrate statistical significance . > 1. , establishing job satisfaction as a critical mechanism that partially explains how environmental and motivational factors drive performance. This dual-mediation model underscores the necessity of cultivating tutor satisfaction alongside structural and motivational interventions to optimize educational outcomes in non-formal learning ecosystems like Kampung Inggris. The research findings provide robust evidence that a positive and significant relationship exists between the work environment and tutor performance within the language training Arifin et al. / Work Environment. Motivation, and Tutor Performance: Job Satisfaction as Mediator in Language Course Institutions IJNI: International Journal of Nusantara Islam Vol. No. : 247-260 institutions (LKP) of Kampung Inggris. Pare. This environment, measured through five key indicators derived from Burden & and Fraser . and Johnson et al . Ae the work environment was assessed through five key aspects: teamwork, student-teacher interactions, available educational resources, participation in decision-making, and innovative teaching strategies Ae was found to be conducive to enhancing tutors' effectiveness. The implication is clear: institutions fostering a superior work environment are likely to experience correspondingly higher levels of tutor performance in their teaching duties. This aligns with theoretical frameworks proposed by Khabri et al . and Kusumastuti et al . , and empirical findings like those of Dolonseda & Watung . , confirming the general principle that a supportive workplace significantly boosts employee performance. Among the work environment indicators, "collaboration," particularly the opportunity to cooperate with fellow tutors, emerged as the highest-rated aspect, signifying its perceived importance in describing the Kampung Inggris LKP context. Analysis of outer loading values further underscored the critical need for adequate school resources, such as videos, recordings, and Tutors explicitly indicated that the availability of such supporting equipment is essential for them to perform their duties maximally, highlighting resource provision as a vital component of the effective work environment in these institutions. Tutor performance itself was measured using four indicators: standards-based planning, standards-based instruction, conditions for learning, and professional responsibilities. Within this construct, "standards-based planning" stood out, specifically the practice of ensuring teaching materials align with relevant standards. The outer loading analysis confirmed that using relevant materials significantly influences tutor performance, reinforcing the link between structured preparation based on established benchmarks and effective teaching outcomes. Complementing the findings on the work environment, the research also established a strong, positive, and significant influence of work motivation on tutor performance. Higher levels of motivation among tutors directly correlated with enhanced performance (Hijriyah et al. , 2. Measured through intrinsic motivation, identified regulation . alue congruenc. , and external regulation, motivation was found to be a powerful driver, consistent with the relationship identified by Wahyudi et al . in organizational settings generally. Regarding work motivation, the indicator "identified regulation," captured by the statement "My job as a tutor is very interesting and enjoyable," received the highest rating. This suggests that tutors in Kampung Inggris predominantly perceive their work as intrinsically rewarding and aligned with their personal values. Furthermore, the outer loading for "external regulation" indicated that tutors also demonstrate high responsibility and discipline in executing their duties, acknowledging the influence of external factors like salary and potential sanctions. The study further demonstrated that the work environment exerts a positive and significant influence on tutor job satisfaction. A better institutional environment leads to higher tutor Arifin et al. / Work Environment. Motivation, and Tutor Performance: Job Satisfaction as Mediator in Language Course Institutions IJNI: International Journal of Nusantara Islam Vol. No. : 247-260 satisfaction, as supported by Lin et al . Job satisfaction was measured through satisfaction with the work environment and satisfaction with the profession. Notably, the indicator reflecting professional satisfaction, specifically the belief that "the benefits of being a tutor clearly outweigh the disadvantages," was the highest-rated item, indicating tutors perceive significant net advantages in their profession. Similarly, work motivation was found to have a positive and significant impact on job The high rating for the value congruence indicator ("interesting and enjoyable") again highlights the role of intrinsic and value-aligned factors in driving satisfaction. Analysis of outer loadings for external regulation also confirmed that tutors feel a sense of obligation and responsibility linked to external rewards and consequences, contributing to their overall work This finding aligns with studies by Irwan et al . Pancasila et al . Prabowo et al . , and Qomariah et al . (Prabowo et al. , 2. Job satisfaction itself was confirmed as a significant positive predictor of tutor performance. Tutors who expressed higher satisfaction, particularly with their profession . gain evidenced by the "benefits outweigh disadvantages" ite. , demonstrated superior performance. This reinforces the established principle that satisfied individuals within an organization tend to exhibit higher levels of performance, as noted by Sofyan et al . (Liu et al. , 2. Crucially, the research identified job satisfaction as a mediating variable. It acts as a partial mediator in the relationship between both the work environment and tutor performance, and between work motivation and tutor performance. While significant direct paths exist from environment and motivation to performance, job satisfaction plays an additional, mediating role. This means that a positive work environment and high motivation enhance performance both directly and indirectly by fostering greater job satisfaction. This partial mediation finding is supported by studies such as Hasibiyadi et al . for the work environment path and Irwan et al . and Qomariah et al . for the motivation path. Despite confirming established relationships, this study holds significant contextual relevance as it was conducted within the unique non-formal education setting of Kampung Inggris Pare's LKP, characterized by andragogical methods, learner choice, and flexible learning environments beyond traditional classrooms (Oktaviana, 2018. Yulianingsih et al. , 2. The confirmation that works environment, motivation, and job satisfaction remain powerful determinants of tutor performance in this distinct context underscores the universal applicability of sound human resource management principles, even within flexible, non-conventional educational The finding that job satisfaction acts as a partial mediator, with direct effects of environment and motivation being stronger, further suggests that in this dynamic setting, intrinsic motivators and a supportive atmosphere are primary performance drivers, with satisfaction reinforcing these effects. Conclusion This study empirically establishes that tutor performance at Language Training Institutions (LKP) in Kampung Inggris is significantly elevated by a supportive work environment Ai specifically through collaborative engagement and accessible pedagogical resources . videos, recording. Concurrently, heightened work motivation, derived from intrinsic professional interest and commitment, directly augments instructional effectiveness. Both environmental conditions and motivational drivers further positively predict tutor job satisfaction, evidenced through occupational fulfillment and institutional advocacy. Job satisfaction itself constitutes a robust direct antecedent of performance outcomes.
