The development of sustainable tourism villages requires the implementation of management practices that enhance environmental performance through environmentally oriented leadership, community participation, and stakeholder engagement in achieving sustainability goals. This study aims to examine the influence of green leadership and community involvement on green performance, with employee engagement serving as a mediating variable among the stakeholders and managers of Punten Tourism Village, Batu City. A quantitative approach with an explanatory research design was employed. The study involved all stakeholders and managers of Punten Tourism Village using a saturated sampling technique. Data were analyzed using Partial Least Squares–Structural Equation Modeling (PLS-SEM) with SmartPLS 4 software. The findings reveal that green leadership and community involvement have positive and significant effects on green performance. Both variables also significantly enhance employee engagement, which, in turn, positively and significantly influences green performance. Furthermore, employee engagement partially mediates the relationships between green leadership and green performance, as well as between community involvement and green performance. These findings suggest that improving the environmental performance of tourism villages requires the integration of green leadership, active community involvement, and stronger stakeholder engagement to support the implementation of sustainable tourism practices.

This study aims to analyze the effect of liquidity and profitability ratios on stock returns through Price to Book Value (PBV) in coal mining companies listed on the Indonesia Stock Exchange (IDX) during 2020-2024. The research uses secondary data analysis from financial reports of the companies collected through documentation techniques, and the data is analyzed using Partial Least Squares (PLS) based on Structural Equation Modeling (SEM). The results show that profitability significantly influences stock returns and PBV, while liquidity has a negative but insignificant effect on PBV and stock returns. Moreover, PBV does not mediate the relationship between liquidity and stock returns or profitability and stock returns. This study recommends that companies focus on improving profitability to enhance stock returns, while investors should consider profitability performance when making investment decisions. Recommendations for future research include adding other independent variables such as leverage or macroeconomic factors and expanding the sector and period coverage for greater generalization.

This study aims to analyze the influence of work motivation and supervision on employee performance through job satisfaction at the Population Control and Family Planning Office (DPPKB) of East Kutai Regency. A quantitative approach was employed using census sampling technique involving 84 employees. Data were analyzed using Structural Equation Modeling-Partial Least Squares (SEM-PLS) with SmartPLS software. The results reveal that: (1) work motivation positively and significantly affects job satisfaction (β = 0.263, p = 0.039); (2) supervision has a stronger positive effect on job satisfaction (β = 0.409, p = 0.000); (3) work motivation does not directly affect employee performance (β = 0.136, p = 0.248); (4) supervision does not directly affect employee performance (β = 0.140, p = 0.186); (5) job satisfaction is the strongest predictor of employee performance (β = 0.565, p = 0.000); (6) job satisfaction does not significantly mediate the work motivation–performance relationship (β = 0.149, p = 0.056); and (7) job satisfaction fully mediates the supervision–performance relationship (β = 0.231, p = 0.001). These findings suggest that improving public-sector employee performance requires a humanistic supervisory approach centered on employee psychological well-being.

This study aims to analyze the effect of career development and organizational culture on employee productivity through job satisfaction at the Office of Community and Village Empowerment (DPMD) in East Kutai Regency. The research employs a quantitative explanatory approach using Partial Least Squares Structural Equation Modeling (PLS-SEM) with SmartPLS software. Total sampling was applied, involving all 90 employees of the office as respondents. Data were collected through questionnaires with Likert scale measurements. The results demonstrate that career development has a significant positive effect on job satisfaction (coefficient = 0.295, T = 2.532, p = 0.011), and organizational culture has a significant positive effect on job satisfaction (coefficient = 0.441, T = 4.071, p = 0.000). However, career development, organizational culture, and job satisfaction do not have a significant direct effect on employee productivity (H3 through H7 rejected). The coefficient of determination for job satisfaction is 43.1%, indicating that both independent variables explain 43.1% of job satisfaction variance. These findings suggest that although career development and organizational culture successfully improve job satisfaction, mechanisms beyond satisfaction are needed to translate that satisfaction into measurable productivity at DPMD.

This study aims to analyze the influence of work motivation, transformational leadership style, and career development on employee performance through job satisfaction at the Dinas PUPR Kabupaten Kutai Timur. This research uses quantitative explanatory method with SEM-PLS (Structural Equation Modeling - Partial Least Squares) analysis. The population consists of 120 employees with a sample of 93 respondents determined using the Slovin formula with 5% margin of error and simple random sampling technique. Data were collected using a Likert scale questionnaire (1-5). The results show that career development has a significant positive effect on job satisfaction (original sample 0.574, p-value 0.000), and transformational leadership style has a significant positive effect on employee performance (original sample 0.540, p-value 0.000). However, work motivation and transformational leadership style do not significantly affect job satisfaction, and work motivation and career development do not directly affect employee performance. Furthermore, job satisfaction fails to mediate the relationship between work motivation, transformational leadership style, and career development on employee performance. The R-Square values indicate that the predictor variables explain 40.4% of job satisfaction variance and 40.1% of employee performance variance.

Financial technology growth via digital wallets in Indonesia offers transaction convenience but challenges Sharia compliance. The main issues involve managing floating funds and cashback rewards, which risk exposure to riba. This study aims to examine and compare riba risk mitigation strategies in both areas. Employing normative legal research with qualitative, comparative, and conceptual approaches, it utilizes library research from DSN-MUI Fatwas, the Qur’an, Hadith, and fiqh muamalah literature. The findings reveal that floating fund riba risks can be minimized by depositing assets in Islamic financial institutions using wadiah or mudharabah contracts to avoid riba nasi’ah. Meanwhile, cashback riba risks are prevented by shifting the contract from qard to ju’alah or hibah mu’allaq, treating incentives as transaction rewards rather than loan benefits. Comparative analysis shows floating fund mitigation is structural, while cashback is reconstructive. Both work effectively under Sharia Supervisory Board monitoring. In conclusion, compliance requires practical execution via appropriate contracts, transparent supervision, and public education. Therefore, contract standardization by DSN-MUI and OJK, alongside enhanced Islamic financial literacy, is necessary.

This research aims to analyze the gap between the profit-sharing principle as the normative foundation of Islamic economics and the risk management practices applied in sharia cooperatives, considering the ongoing inconsistencies in the implementation of the risk-sharing principle. The research method employs a qualitative approach thru literature study with thematic and comparative analysis techniques on relevant academic literature. The results and discussion indicate that sharia cooperatives tend to adopt a conventional risk management paradigm oriented toward institutional stability, thereby triggering the dominance of non-profit-sharing contracts and the shift of the concept of risk sharing to risk shifting in operational practices. The gap is influenced by structural factors, including limitations in managerial capacity, information asymmetry, potential moral hazard, and pressures of institutional sustainability. This study concludes that the risk management practices of sharia cooperatives do not fully reflect the principles of Islamic economics, thus necessitating a reconstruction of a more integrative and contextual risk management model. As a suggestion, sharia cooperatives need to develop a risk management framework based on risk sharing that is adaptive to operational risks without disregarding the values of justice and partnership as the main characteristics of Islamic economics.

A bustier plays a crucial role in supporting the body, enhancing its shape, and enhancing aesthetics, especially when worn with a kebaya or evening gown. This study aims to analyze the results of bustier production using three different types of boning, such as needle-inserted boning, sewn-in boning, and steel boning, to determine the most optimal type of boning. The method used is Research and Development (R&D), encompassing data collection, product design, validation, testing, and product revision. This study found that the bustier with inserted boning achieved fairly good results with an average score of 3.00, which equates to 75.00% and falls into the “acceptable” category, while the bustier with sewn-in boning demonstrated the most optimal results. Based on validation testing by two expert validators, this product received an average score of 3.64 out of a total of 4, with a 90.91% acceptability rate, which falls into the “highly acceptable” category. The bustier with steel boning received an average score of 2.82, or 70.45%, which also falls into the “acceptable” category. Steel boning is not yet widely available, so its availability should be confirmed before production begins. Installing both sewn boning and steel boning requires precision. Therefore, it is recommended that you first practice structural sewing techniques.

Sandwich composites are lightweight structural materials with a high strength-to-weight ratio and have potential as alternatives to conventional materials. This study aims to analyze the effects of core thickness variation and the number of skin layers on the bending strength of fiberglass-skinned sandwich composites with an A-flute cardboard honeycomb core. The research employed an experimental method using three-point bending tests in accordance with ASTM C393. Core thicknesses of 10 mm, 20 mm, and 30 mm were investigated, while the number of fiberglass skin layers was varied at 1, 2, and 4 layers. Bending strength was evaluated based on core shear strength and skin bending stress, expressed in MPa. The results show that the highest average core shear strength was obtained at a core thickness of 10 mm with 4 skin layers, while the lowest value occurred at a core thickness of 30 mm with 1 skin layer. The highest skin bending stress of 43.40 MPa was achieved by the specimen with a 10 mm core thickness and 1 skin layer, whereas the lowest value of 11.83 MPa was observed at a 30 mm core thickness with 4 skin layers. These results indicate that increasing core thickness tends to reduce bending strength based on core shear strength, while increasing the number of skin layers enhances the bending performance of the sandwich composite, and an interaction effect between the two variables is present.

This study aims to examine the historical origins and development of the sociology of education, explore the biographies and ideas of key scholars from both Islamic and Western traditions, and analyze their relevance in the context of modern education. The development of education has always been closely linked to social, political, and economic dynamics, which gave rise to the sociology of education as a discipline that investigates the relationship between education and social change. Contemporary challenges such as social inequality, the impacts of globalization and technological advancement, and the growing demand for the democratization of education require a comprehensive examination of the major sociological theories that have emerged over time. This research employs a qualitative approach using a literature review method through the analysis of relevant books and scholarly journal articles. The findings indicate that the ideas of scholars such as Ibn Khaldun, Auguste Comte, Émile Durkheim, Karl Marx, Max Weber, Herbert Spencer, George Herbert Mead, Talcott Parsons, and Ali Shariati have made significant contributions to understanding the functions, conflicts, and interactions within education. Structural functionalist, conflict, and symbolic interactionist theories provide complementary analytical frameworks for explaining education’s role as a means of social integration, an arena for the reproduction of inequality, and a space for the construction of meaning and identity. By adopting a comparative approach across different intellectual traditions, this study offers a holistic perspective for the development of the sociology of education in the modern era.

The proliferation of social media interactions frequently results in an increased risk of cyberbullying. This study aims to evaluate the impact of digital literacy, digital security, and digital communication on cyberbullying prevention among Generation Z TikTok users. Employing an explanatory quantitative approach, data were collected through online questionnaires distributed to Generation Z students in the Information Systems Study Program at Universitas Internasional Batam. The respondent data were then analyzed using the Partial Least Square-Structural Equation Modeling (PLS-SEM) technique. The analytical results reveal that digital literacy does not significantly affect cyberbullying prevention. Conversely, both digital security and digital communication demonstrate a significant impact on cyberbullying prevention. Among the investigated variables, digital communication exerts the most dominant influence on preventing cyberbullying. These findings suggest that preventing cyberbullying requires more than merely digital knowledge; it heavily relies on the implementation of digital security measures and the capacity for ethical communication in digital environments. Ultimately, this research is expected to serve as a valuable reference for formulating effective cyberbullying mitigation strategies for Generation Z across social media platforms.

This study aims to identify and analyze the logical fallacies that arise in public conversations about environmental issues and natural resource management on Indonesian social media using a descriptive qualitative approach. Data were collected through scraping techniques using the Python programming language and subsequently analyzed using an informal logic framework to identify various forms of fallacious reasoning. The findings reveal the presence of multiple fallacies that substantially influence public understanding of causal relationships within environmental dynamics. These fallacies contribute to oversimplification, shifts in attention away from scientific evidence, and the emergence of distorted perceptions regarding structural factors in spatial planning and natural resource governance. This study contributes to environmental communication scholarship by emphasizing the importance of critical thinking literacy in improving the quality of public deliberation and supporting the formulation of evidence-based environmental policies.

Limited land availability is a major constraint in developing school infrastructure in active urban educational facilities. This study evaluates the classroom development plan at SDN 39 Lubuklinggau from the perspective of a planner, focusing on land limitation, functional needs, safety, constructability, and long-term building performance. A descriptive-evaluative approach was applied through technical observation, document review, alternative assessment, weighted scoring, and risk analysis. The results indicate that horizontal expansion is constrained by limited open space and may reduce internal circulation, student activity areas, and emergency space. Three alternatives were compared: horizontal expansion, building rearrangement, and a two-storey classroom scheme. The two-storey alternative obtained the highest score of 84, compared with 61 for rearrangement and 56 for horizontal expansion. However, its feasibility depends on further soil investigation, structural design, staircase and evacuation safety, utility coordination, construction phasing, and strict site safety control. The study recommends that the planner prioritize detailed site measurement, geotechnical investigation, detailed engineering design, construction safety planning, and post-construction functional evaluation. A vertical classroom strategy can be considered a rational solution for land-constrained schools when supported by accountable technical planning and integrated project control.

The development of the internet and social media has encouraged e-commerce companies to utilize digital platforms as a marketing tool, one of which is Shopee through TikTok social media. The high frequency of digital advertising is thought to influence consumer attitudes, especially among Generation Z as active TikTok users. To determine the impact of Shopee's digital advertising frequency on consumer attitudes using promotions as a mediating variable on Generation Z TikTok social media users in Tasikmalaya, this study employed quantitative, descriptive, and verification techniques. A total of 100 respondents were sampled using purposive sampling techniques. An online questionnaire with a Likert scale of 1 to 5 was used to collect research data. Data were analyzed using Structural Equation Modeling-Partial Least Square (SEM-PLS) with the help of SmartPLS 4. The results showed that advertising frequency significantly and positively influenced consumer attitudes and promotions. In addition, promotions can mediate the effect of advertising frequency on consumer attitudes and have a beneficial and significant impact. These results indicate that consumer opinions towards Shopee will be more positive if advertisements are displayed more frequently and supported by appropriate promotions. This study serves as an academic reference and information source for businesses seeking to optimize social media-based digital marketing strategies.

Substandard housing remains a multidimensional urban problem because it intersects with structural safety, indoor environmental quality, sanitation, clean water, poverty, and the effectiveness of policy implementation. This study evaluates the implementation of the substandard housing improvement program (RTLH) in Lubuk Linggau City by integrating a technical audit of housing quality with an implementation analysis based on the variables of communication, resources, implementer disposition, and bureaucratic structure. A descriptive-evaluative mixed approach was applied through field observation, technical scoring of ten rehabilitated houses, document review, and structured interviews with regulators, field facilitators, and beneficiary households. The results show that the cumulative technical conformity index reached 3.325 out of 4.00, equivalent to 83%, and was classified as adequate housing. Structural resilience achieved the highest score at 88%, followed by space adequacy at 85%, natural lighting and ventilation at 80%, and sanitation and clean water at 75%. Five houses were classified as adequate housing, while five were classified as fairly adequate/light substandard housing. The implementation analysis indicates that clear practical communication and facilitator assistance strengthened structural quality, but limited financial resources, weak environmental-health prioritization, and administratively oriented supervision reduced sanitation and ventilation performance. The study recommends standardized septic systems, stronger post-construction technical verification, healthy-housing education, realistic unit budgets, and quality-oriented monitoring.

Cracker pr machines are widely used in small and medium-scale food industries. However, limitations in frame design and motor speed control often result in suboptimal machine performance. This study aims to perform a redesign of the upper conveyor frame, analyze the structural strength of the frame, and evaluate the effect of using a Variable Speed Drive (VSD) inverter on improving the production capacity of a cracker printing machine.The research method includes frame redesign, load calculation, and numerical analysis using the Finite Element Method (FEM) with SolidWorks Simulation. The applied loads consist of machine component weights and operational loads. In addition, performance testing was conducted by varying the motor rotational speed controlled by the VSD inverter to determine its effect on production output.The results show that the redesigned frame has a maximum displacement of 0.18 mm, a maximum stress of 8.9 MPa, and a minimum safety factor of 31, indicating that the structure is safe and operates within the elastic region. The implementation of the VSD inverter successfully increased the machine’s production capacity from the initial condition up to 78.5 kg/h. Based on these results, it can be concluded that the frame redesign and the application of a VSD inverter are effective in improving the performance and reliability of the cracker printing machine.
