Tawangsari Hamlet, Tejosari Village, Ngablak District, Magelang Regency, faces serious waste management challenges, reflected in the high daily waste production and the inactivity of waste banks post-COVID-19. To address this issue, the Tidar University Community Service Program (KKN) was implemented, aiming to improve environmental cleanliness through active community participation. This program also supports the achievement of the "Climate Action" goal in the Sustainable Development Goals (SDGs), which focuses on combating climate change caused by air pollution and reducing environmental pollution. The method used in this program is Participatory Action Research (PAR), which is oriented towards community empowerment by involving all stakeholders in every stage of implementation. The activity began with a series of observations to understand the condition of waste management in the community. Then, a waste management tool was created in the form of a smoke-free waste incinerator, which aims to manage inorganic waste in an environmentally friendly manner. In addition, trash bins to facilitate waste sorting at the household level were also provided. Socialization and mentoring for the community, especially youth organizations, were carried out to introduce and educate them on the correct use of incinerators and waste sorting. A demonstration of incinerator use was also conducted with the community, which proved to increase understanding and active participation. The implementation of the incinerator and waste sorting facility demonstrated that these measures were effective in addressing the waste problem in Tawangsari Hamlet and contributed to a cleaner and healthier environment. Furthermore, the program successfully raised environmental awareness among the Tawangsari Hamlet community. Through direct involvement in the waste management process, residents not only gained new knowledge about the importance of waste sorting but also experienced the direct benefits of implementing smoke-free incinerator technology.Keywords: waste management, low-smoke incinerator, Climate Action, SDGs, community empowerment, environmental pollution, Magelang Regency

Digital transformation in the public sector has become a strategic agenda to improve the efficiency, transparency, and quality of government services, including in regional revenue management. This study aims to analyze the implementation of digital transformation in the Regional Revenue Agency (Bapenda: Badan Pendapatan Daerah) of East Java Province, especially in the Gresik Technical Implementation Unit (UPT: Unit Pelaksana Teknis), as well as its impact on administrative efficiency, transparency, and increasing Regional Original Revenue (PAD: Pendapatan Asli Daerah). This study uses a non-empirical qualitative approach with a literature study method, which involves the analysis of secondary data from scientific journals, policy documents, government performance reports, and community digitalization indicators such as the Indonesian Digital Society Index (IMDI: Indeks Masyarakat Digital Indonesia). The results show that digital transformation through e-payment systems and web-based administration has significantly accelerated the service process, improved taxpayer compliance, and reduced revenue leakage. The receipt of PAD through digital channels increased by 60% in one year, while service efficiency increased by reducing administrative process time from three days to one day. The implementation of this digital transformation is also influenced by the readiness of infrastructure, apparatus competence, and community digital literacy, as described in the theoretical framework of the Technology Acceptance Model (TAM), Dynamic Capabilities, and TOE Framework. Despite positive achievements, challenges such as digital skills gaps, resistance to change, and system security issues are still obstacles in optimizing digital transformation. This research makes a theoretical contribution to the development  of e-governance literature  and digital public policy practices at the local level. These findings also provide concrete recommendations for other regions to replicate good practices of digital transformation that have succeeded in improving regional financial performance. Thus, digital transformation is not only a technological instrument, but also a governance strategy that requires synergy between technology, organizations, and society

This study examines the effectiveness of education and training programs in improving employee performance and identifies the factors influencing training outcomes at the Personnel and Human Resources Development Agency (BKPSDM) of Southwest Papua Province.

This study aims to describe the application of the Jigsaw Learning method in Islamic Religious Education (PAI) learning at SMP 3 Sendana and to identify the advantages and obstacles encountered during the learning process. The research method used is descriptive qualitative, with data collection techniques through observation, interviews, and documentation. The results of the study indicate that the application of the Jigsaw Learning method can increase student activeness, strengthen group cooperation, and help understand the material more deeply and comprehensively. In this activity, students not only act as recipients of information from the teacher, but also as conveyors of material to their group mates. The process of sharing information between members encourages students to be more active in seeking out, understanding, and explaining the concepts being studied. In addition, this method also creates a collaborative and enjoyable learning atmosphere, due to the positive social interactions between students. This can increase a sense of responsibility and concern for the success of the group. However, in its implementation, several obstacles were found that require attention. Some of these include limited study time within the available lesson hours, inequality in contributions between group members which sometimes results in an uneven workload, and a lack of student readiness to understand the material independently before the group discussion process takes place. Despite the challenges, these obstacles can be minimized through effective classroom management, such as balanced group division, motivation, and intensive teacher support throughout the learning process. With the right strategy, Jigsaw Learning remains an effective and relevant method for Islamic Religious Education (PAI) learning, as it encourages the achievement of learning objectives in a participatory, active, and enjoyable manner. Therefore, this method is a worthy alternative to cooperative learning that can improve the quality of religious education at the junior high school level.

This study aims to evaluate the soundness of PT Bank Panin Tbk during the 2014–2024 period using the RGEC method, which assesses four key dimensions: risk, governance, earnings, and capital. This research approach is quantitative and descriptive, utilizing secondary data sourced from annual reports, financial statements, and officially published corporate governance documents. Each component is analyzed using relevant indicators, such as the NPL ratio, LDR, PDN, ROA, ROE, BOPO, NIM, and CAR. The results indicate that PT Bank Panin Tbk's risk profile, as reflected in the NPL, PDN, and LDR ratios, is largely in the healthy category, demonstrating the bank's ability to effectively manage credit and liquidity risks. An evaluation of corporate governance, based on consistent self-assessment reports over ten years, also demonstrates the achievement of a healthy rating, reflecting the bank's commitment to maintaining the principles of transparency, accountability, and regulatory compliance. Regarding earnings, profit performance, as measured by ROA, ROE, BOPO, and NIM, shows stable and positive results, confirming the bank's ability to generate sustainable profits. Meanwhile, in terms of capital, the CAR ratio recorded excellent performance and was a dominant factor in maintaining capital resilience while meeting the capital adequacy standards set by regulators. These findings confirm that PT Bank Panin Tbk was in overall good health throughout the study period. The results of this study are expected to provide strategic input for bank management in maintaining positive performance and for regulators as material for evaluating banking policies.  

Vocational education in Indonesia faces a serious challenge in the form of a gap between the competencies of Vocational High School (SMK) graduates and the evolving needs of the workforce. Timika City, despite having the largest number of vocational high schools (SMK) in Papua, has not yet fully demonstrated optimal educational management quality, particularly in the aspect of school administration. This condition has resulted in low effectiveness in data recording, documentation of industrial work practices, and reporting and evaluation of partnerships with the business and industrial world (DUDI). This study aims to explore and analyze administrative management strategies that can improve educational quality while strengthening the work readiness of vocational high school students in Timika City. The research method used is a descriptive qualitative approach with content analysis of secondary data, including government policy reports, educational statistics, and the latest scientific literature. The results show that weaknesses in the administrative system are one of the factors inhibiting the achievement of competitive vocational education quality. The implementation of management strategies based on Total Quality Management (TQM) principles, particularly through the Plan–Do–Check–Act (PDCA) cycle, data-driven decision-making, and the involvement of all school elements, has proven effective in increasing the efficiency and accountability of administrative services. The discussion also emphasized the importance of transformational leadership from school principals, developing the competencies of administrative staff, utilizing information technology in administrative systems, and strengthening strategic partnerships with the industrial and industrial sectors (DUDI). Therefore, it can be concluded that school administrative management is not merely a technical function, but rather a strategic component in building a vocational education ecosystem that is adaptive, relevant, and oriented to the needs of the workplace. This research recommends that school policymakers and local governments strengthen administrative governance systems to support educational quality and improve the job readiness of vocational high school graduates.

This study investigates the relationship between fiscal dependence, the effectiveness of locally generated revenue (PAD), and the degree of fiscal decentralization on the Human Development Index (HDI) in four regencies on Madura Island Bangkalan, Sampang, Pamekasan, and Sumenep which have consistently reported the lowest HDI scores in East Java Province. Utilizing panel data from 2011 to 2023, the findings indicate that all regencies remain highly fiscally dependent, with fiscal dependency ratios exceeding 89%. Central government transfers dominate local budget structures, significantly limiting local fiscal autonomy. While PAD effectiveness shows notable achievements such as Pamekasan’s 136.09% realization rate its contribution to total regional revenue remains relatively low. This is reflected in the modest degree of fiscal decentralization, which ranges between 8.56% and 10.72%. Such fiscal limitations hinder the ability of local governments to invest in strategic sectors that directly impact human development, including education, healthcare, and public services. The analysis also reveals that despite effective PAD realization, its nominal value is insufficient to drive substantial improvements in HDI, especially when not supported by strengthened fiscal capacity and local economic mobilization. These findings suggest that PAD effectiveness alone does not translate into better human development outcomes without broader fiscal empowerment. Therefore, a comprehensive fiscal decentralization strategy is required one that not only enhances revenue generation but also improves budgetary governance and optimizes local economic resources. Strengthening local fiscal autonomy is essential for ensuring targeted, efficient, and equitable investment in human development sectors, ultimately fostering sustainable regional development across Madura Island.

Community-based village development serves as a crucial strategy to reduce regional disparities and enhance village self-reliance. However, among the 36 villages in Bintan Regency, only two were categorized as Independent Villages in 2023, one of which is Toapaya Selatan Village. This study aims to examine how community participation contributes to the achievement of Independent Village status in Toapaya Selatan. The research applied a descriptive qualitative method, with data collected through observation, interviews, and documentation involving 15 informants. The findings reveal that community participation occurred actively across four key stages: decision-making, implementation, benefit-taking, and evaluation. In the decision-making process, residents were engaged through structured deliberations beginning at the neighborhood (RT) level and culminating in the village development planning meeting (Musrenbangdes). In the implementation stage, participation was reflected in both physical development projects and empowerment activities that fostered local capacity. The benefit-taking stage showed that residents equitably shared the outcomes of development through a system of regional rotation and principles of fairness. In the evaluation stage, the community was provided with both formal and informal spaces to voice aspirations and feedback, ensuring accountability and inclusiveness in governance. Despite the relatively high level of participation, several challenges persisted, including the dominance of representative systems, which limited direct involvement of broader community members, and the need for stronger capacity-building efforts. These findings suggest that while Toapaya Selatan Village has successfully demonstrated the potential of community-based participation in achieving independent status, sustaining and replicating this success in other villages requires continuous strengthening of community capacity, more inclusive participatory mechanisms, and institutional support. Strengthening these aspects will not only enhance the quality of participation but also ensure sustainable development outcomes that can be applied as a model for other villages.

This study aims to explore the relationship between work motivation and discipline on the performance achievement of Catholic Religious Education (PAK) teachers in the Semarang region. The research uses a quantitative survey approach, collecting data from 15 PAK teachers through a validated questionnaire. The instruments used to measure work motivation are based on Maslow’s hierarchy of needs for the motivational aspect, while discipline is measured using indicators developed by Rivai, and performance achievement is evaluated based on parameters defined by Robbins. The findings show that motivational drive contributes 50.5% to performance achievement (R² = 0.505, p = 0.003). This indicates that work motivation has a significant impact on performance, although its contribution is lower compared to discipline. In contrast, discipline contributes more significantly to performance achievement, accounting for 66.2% (R² = 0.662, p = 0.000). This suggests that discipline is a more dominant factor in improving the performance of Catholic Religious Education teachers, as discipline is critical in achieving optimal performance. Simultaneous analysis reveals that the combination of motivation and discipline explains 72.6% of the variation in performance achievement (R² = 0.726, F = 13.893, p = 0.000). This result indicates that both variables are significantly related to performance achievement when considered together. However, partial tests show that only discipline has a significant independent impact on teacher performance, with p = 0.121, while motivation does not have a significant effect when considered separately. This study concludes that discipline functions as the main mediator in the relationship between work motivation and performance achievement. Therefore, it is essential to strengthen discipline in efforts to improve teacher performance, particularly in the context of Catholic Religious Education.

This community service program aims to improve the quality of services at Puskesmas (community health centers) through intensive assistance in content creation and digital communication media. The main issue addressed is the low digital literacy among healthcare workers at Puskesmas in managing effective communication media to reach the public. This has led to low community participation in health programs run by Puskesmas. Therefore, this program is designed to enhance healthcare workers' skills in utilizing digital technology for health promotion and improving communication effectiveness with the public. The program implementation involves several stages: (1) an initial survey to assess the condition of existing communication media, (2) training on creating engaging and informative health education content, (3) workshops on graphic design and health promotion video creation, (4) guidance on using social media platforms to disseminate health information, and (5) continuous evaluation and monitoring to ensure the sustainability of the program. This activity involves 25 healthcare workers from 5 selected Puskesmas, with a mentoring duration of 6 months. The results show significant improvements, including: an increase in healthcare workers' ability to create digital content from 30% to 85%, a 200% increase in public engagement with health information, and a 150% increase in the coverage of health promotion services. Additionally, the program has produced 120 pieces of health education content, 15 health promotion videos, and 8 successful digital campaigns that have successfully enhanced public participation in health programs. The long-term impact of this program is the increased public awareness of preventive health and improved access to Puskesmas services. This program can also be replicated in other regions as a model for improving the quality of primary healthcare services through optimal use of digital technology, which can accelerate the achievement of national health development goals.

Batam City, as an industrial hub in the Riau Islands Province, plays a vital role in the region’s economic growth. However, a surge in inflation can affect investment interest, as investors tend to avoid areas with economic uncertainty. One of the main contributors to inflation in Batam is the food component, which experiences high demand, especially during certain periods such as religious holidays and the arrival of international tourists. Batam, which is not a food-producing area, faces significant challenges in meeting agricultural needs and currently remains dependent on supplies from outside the region. Geographic constraints, such as inefficient logistics, weather disruptions, and institutional weaknesses in the food sector, further aggravate inflation control efforts. In addition, hilly terrain and less fertile land limit the types of crops that can be cultivated, making food price stability critically important. This study aims to evaluate the effectiveness of the Low-Cost Market Operation Team Program (Tim Operasi Pasar Murah) in Batam City in 2024. The method used is Sequential Explanatory Design with a mixed-methods approach. Quantitative findings indicate that the average success rate of the program is 85.93%, with a target achievement rate of 90.12% and a satisfaction level of 86.11%. Qualitative results suggest that the policy of conducting low-cost market operations has been appropriate and carried out by authorized institutions, with strong collaboration between the government and the private sector. The program has succeeded in maintaining price stability ahead of the fasting month and Eid al-Fitr, receiving positive responses from the community and demonstrating good internal coordination. In conclusion, the low-cost market operation program in Batam City has been effective in curbing inflation before the fasting month and Eid al-Fitr. However, for comprehensive inflation control, relying solely on this program is insufficient. Additional strategies are needed to ensure sustainable food price stability.

This study aims to (1) determine the level of learning motivation among students at MTs Muhammadiyah 1 Singkawang, (2) identify the physics learning achievement of students at MTs Muhammadiyah 1 Singkawang, and (3) examine the influence of learning motivation on students’ physics learning achievement. The research employed a survey method with simple linear regression analysis, which is used to model the relationship between one dependent variable and one independent variable. The population consisted of all students at MTs Muhammadiyah 1 Singkawang, and the sampling technique applied was total sampling. Data were collected through a student learning motivation questionnaire and documentation of students’ physics grades.Descriptive analysis results indicated that the learning motivation variable had an average score of 85, which, based on the categorization criteria, falls into the very high category. In terms of physics learning achievement, data analysis revealed that the highest frequency was within the score interval of 30 < X ≤ 70. Specifically, 39 students (34%) were categorized as medium achievers, while 35 students (30%) were categorized as low achievers. These findings indicate that overall, students’ physics learning achievement can still be considered high, although a significant proportion remains in the medium and low categories.The results of simple linear regression analysis demonstrated a positive influence of learning motivation on physics learning achievement. This suggests that higher levels of learning motivation are associated with better physics performance among students. The findings highlight the importance of fostering and maintaining high learning motivation levels to enhance academic achievement. Therefore, educators are encouraged to design and implement learning strategies that not only improve students’ understanding of physics concepts but also stimulate and sustain their motivation to learn.

In the textile industry, quality control is a crucial aspect to ensure the stability and consistency of production results. One of the important stages in yarn production is the warping process, which has a significant influence on the quality in the subsequent process. This study aims to apply the Statistical Process Control (SPC) method to assess the quality of 40 CD KNB yarn in the warping process in the GKBI PC company, Preparation Department, and determine whether the process is already in a controlled condition. Currently, the average quality and amount of monthly yarn production show fluctuations with a downward trend of 1.64 per 5,000,000 meters in the period February–July 2024. This figure is below the company's daily production target of 1.00 per 5,000,000 meters, so the target has not been achieved. This discrepancy indicates the need for a more systematic evaluation and improvement of the quality control system. Based on the analysis of the X-Bar control chart in January 2025, two data points were found outside the control limits (UCL = 176.8; LCL = -29.5; average = 73.6), ie on January 4 and 20. The main cause of such uncontrollability is the weak yarn that comes from the rewinding process. Check sheet analysis and Pareto diagram shows that the most common factors causing thread breakage are weak threads. Furthermore, through the cause-and-effect diagram (fishbone diagram), it was identified that the factors that cause thread breakage come from four categories: human (HR), material (raw material), environment, and machine. Of the four factors, human resources and material aspects are the biggest contributors to influence. Therefore, it is recommended that quality control at PC GKBI be strengthened through training and counseling programs to employees, in order to improve skills and awareness of the importance of quality. This step is expected to reduce the rate of yarn breakage, maintain the stability of the production process, and ensure consistent achievement of company targets.

Improving the quality of biology learning in secondary schools requires pedagogical innovations that connect academic content with real-life contexts and leverage digital technology. This study aims to analyze the effect of a contextual teaching approach assisted by interactive PowerPoint on students’ learning outcomes in the human respiratory system topic. A true experimental design with a pretest–posttest control group was employed at SMA Negeri 1 Langowan, involving two eleventh-grade classes selected through simple random sampling. The experimental class received contextual instruction integrated with interactive PowerPoint, while the control class was taught using conventional methods. Data were collected through validated achievement tests and analyzed using normality and homogeneity tests, followed by independent and paired t-tests. The results indicate a significant improvement in learning outcomes for students in the experimental class compared to the control group. The experimental group’s posttest scores were substantially higher, and the difference was statistically significant. Integrating a contextual approach with interactive visualization effectively enhanced students’ understanding of abstract biology concepts, promoted active participation, and strengthened learning motivation. These findings support constructivist theory and highlight the relevance of contextual teaching in science education aligned with the Merdeka Curriculum. The study implies the importance of implementing context-based strategies combined with simple digital media to improve biology learning effectiveness. Future research may explore its impact on non-cognitive skills such as critical thinking and scientific attitudes. Furthermore, the results of this study provide opportunities for teachers to be more creative in designing teaching materials that are not only informative but also interactive and relevant to students' lives. By utilizing media such as interactive PowerPoint, teachers can present complex biological content in a more engaging and understandable way.

This study aims to determine the effectiveness of mindfulness training in reducing academic stress levels in college students. The background of this study is based on the high academic pressure experienced by college students, which can impact mental health, learning motivation, and academic achievement. Mindfulness was chosen as an intervention because this approach focuses on increasing full awareness of the present moment in a non-judgmental manner, which is believed to help individuals manage stress more adaptively. The study population was college students, with a sample of 15 participants selected using a simple random sampling technique. The study was conducted in a psychology laboratory under controlled conditions to minimize confounding factors. The research approach used was quantitative with an experimental design. The academic stress measurement instrument consisted of 31 items compiled based on the theory of Sarafino and Smith, which has been tested for validity and reliability. The research procedure included measuring academic stress levels before and after mindfulness training. Data analysis was carried out using a t-test to examine differences in pre-test and post-test scores, and a correlation test to examine the relationship between mindfulness application and stress reduction. The results showed a significance value of 0.00 (p < 0.05) and a correlation value of 0.991, which means Ha was accepted. These findings indicate a very strong positive relationship between mindfulness training and reduced academic stress levels. Therefore, it can be concluded that mindfulness training is effective in reducing academic stress in college students. The implication of this study is the need for higher education institutions to consider mindfulness training programs as a preventive and curative intervention strategy to maintain student mental health, enabling them to face academic demands more healthily and productively.

This study aims to determine the effectiveness of the media-assisted differentiation method in improving the ability to memorize Arabic vocabulary in grade III students of MI Salamah. The background of this study is based on the phenomenon of low student ability in memorizing vocabulary due to teaching techniques that tend to be monotonous and repetitive, thus less motivating students to learn actively. This study uses the Classroom Action Research (CAR) approach referring to the John Elliot model, which is implemented in two cycles, each including the planning, action implementation, observation, and reflection stages. The subjects of the study were 26 grade III students. Data were collected through oral examinations, interviews, and observations of teaching and learning activities. The results of the study showed a significant increase in students' ability to memorize vocabulary after the application of the media-assisted differentiation method. In Cycle I, the average percentage of student and teacher activity achievement was 72%, with only 61.54% of students being able to reach the memory test passing standard. After the strategy improvement in Cycle II, the average student and teacher activity increased to 90%, while the percentage of students reaching the memory test passing standard jumped to 92.30%. This improvement demonstrates that the differentiation method, which utilizes learning media, provides more varied, engaging stimuli, and is tailored to each student's learning characteristics. The conclusion of this study is that the media-assisted differentiation method is effective in improving elementary school students' memorization of Arabic vocabulary. The implication of this finding is the importance of teachers implementing creative, adaptive, and media-based learning approaches to optimize Arabic language learning outcomes, particularly vocabulary mastery.

This study examines the effectiveness of the SIM Nasional Presisi (SINAR) application in facilitating the renewal of driver’s licenses at the Driver’s License Administration Unit (SATPAS SIM) of Polda Metro Jaya, DKI Jakarta. The SATPAS is responsible for managing and issuing driver’s licenses, and recent technological advancements have enabled a transformation of the renewal process from an in-person service to an entirely online platform via the SINAR application. This innovation eliminates the need for applicants to physically visit the SATPAS office, offering greater accessibility and efficiency. The research adopts a qualitative descriptive approach, with data gathered through observation, structured interviews with relevant stakeholders, and documentation analysis. Campbell’s (1989) Program Effectiveness Theory serves as the analytical framework, utilizing five evaluation indicators: (a) program success, (b) program target determination, (c) program satisfaction, (d) input and output levels, and (e) overall goal achievement. Findings reveal that the SINAR application effectively integrates the issuance and renewal processes by connecting directly to the Korlantas Polri SIM Data Center. This integration ensures seamless verification and processing of applications. The program has achieved its intended targets, particularly in meeting public needs for a fast, accurate, and convenient service. The shift to online renewals has significantly reduced processing time and logistical burdens for applicants, contributing to a notable increase in the number of SIM renewals in 2023 compared to previous years. Furthermore, user feedback indicates high satisfaction levels, largely due to the convenience of remote access, the clarity of procedural instructions, and the reliability of the application’s features. Despite minor technical challenges, the overall implementation of the online SIM renewal service at SATPAS Polda Metro Jaya is deemed highly effective.

Taxpayer compliance is a crucial factor in optimizing state revenue, particularly in supporting national development financing. However, in practice, various obstacles are still encountered that hinder the achievement of optimal compliance levels. Some of these include employees' low understanding of tax provisions and the less than optimal effectiveness of tax sanction implementation. This study aims to analyze the relationship between tax knowledge (X1) and tax sanctions (X2) on taxpayer compliance (Y) among employees of the Banten Province Cooperatives and SMEs Office. This study uses a quantitative method with an associative approach. The sampling technique uses saturated sampling, so that the entire population of 45 people is used as the research sample. Data analysis was performed using the Partial Least Square (SEM-PLS) based Structural Equation Modeling method using SmartPLS software version 4.0. The results show that the tax knowledge variable (X1) has a t-statistic value of 1.190 <1.96 and a significance value (p-value) of 0.234 >0.05. Thus, tax knowledge does not have a significant effect on taxpayer compliance. Furthermore, the tax sanction variable (X2) obtained a t-statistic value of 1.436 < 1.96 and a p-value of 0.151 > 0.05, which means that tax sanctions also do not have a significant effect on taxpayer compliance. Overall, this study concludes that neither tax knowledge nor tax sanctions partially have a significant effect on the level of taxpayer compliance among the employees who were respondents in the study. This finding indicates that other factors, such as personal awareness, perceptions of tax fairness, and intrinsic motivation, may have a more dominant role in shaping taxpayer compliance. Therefore, a more comprehensive policy strategy is needed to increase compliance, not only through increasing knowledge or enforcing sanctions, but also through ongoing coaching, socialization, and persuasive approaches.

This study aims to examine the influence of self-efficacy and learning environment on learning outcomes, with learning motivation as a mediating variable, among students of SMK Negeri 44 Jakarta. Employing a quantitative approach with a survey method, the research involved a population of 175 students, all of whom were included as the sample through a total sampling technique. Data analysis was conducted using Structural Equation Modeling–Partial Least Squares (SEM-PLS) with SmartPLS 4.0 software. The analytical procedures encompassed measurement model analysis, structural model analysis, and hypothesis testing for both direct and indirect effects.The findings reveal a positive and significant direct effect of self-efficacy on learning outcomes, indicating that students with higher confidence in their abilities tend to achieve better academic performance. Similarly, the learning environment was found to have a positive and significant direct effect on learning outcomes, suggesting that supportive academic surroundings contribute meaningfully to student achievement. However, the study found no significant direct effect of learning motivation on learning outcomes, nor any significant mediating role of learning motivation in the relationships between self-efficacy and learning outcomes or between learning environment and learning outcomes. These results imply that while self-efficacy and a conducive learning environment are key determinants of academic success, the role of learning motivation as an intervening variable may not be as substantial in this context. The absence of mediation suggests that motivation alone may not bridge the gap between personal and environmental factors and actual academic performance. This study contributes to educational research by providing empirical evidence on the complex interplay between psychological, environmental, and motivational factors influencing student achievement, highlighting the need for educators to strengthen both self-belief and learning conditions to optimize outcomes.
