This study aims to determine the effect of academic self-efficacy on academic performance in the 2021 intake of students at Padang State University. Academic self-efficacy is an individual's belief in their ability to complete academic tasks, which is believed to play a significant role in determining student academic achievement. This study used a quantitative approach with a survey method, involving 55 respondents as a sample. Data collection was carried out through a questionnaire using a Likert scale to measure students' academic self-efficacy levels, as well as data collection on their Grade Point Average (GPA) as an indicator of academic performance. Data analysis was carried out using the SPSS program, through several testing stages, namely instrument validity and reliability tests, and simple linear regression tests to determine the effect of independent variables on the dependent variable. The results of the analysis indicate a positive and significant influence between academic self-efficacy and academic performance. This is evidenced by the regression coefficient value of 0.009, with a calculated t-value of 15.278, which is greater than the t-table of 2.266, and a significance value of 0.006, which is less than 0.05. These findings indicate that the higher a student's level of confidence in their academic abilities, the better their academic achievement. Therefore, developing academic self-efficacy can be an important strategy for improving the quality of learning and student academic achievement.  

This study aims to analyze the influence of learning interest, learning discipline, and critical thinking skills on student learning outcomes in the Simple Financial Processing subject for class XI MPLB at SMK PGRI 2 Sidoarjo. Learning outcomes are understood as skills or abilities acquired by students after participating in the learning process, the success of which is measured through scores in the form of numbers, symbols, or letters. Three factors selected in this study as independent variables are learning interest, learning discipline, and critical thinking skills. This type of research is quantitative research with an explanatory approach, which aims to explain the cause-and-effect relationship between these variables.

Data collection was carried out by distributing questionnaires to students. The data obtained were then analyzed using SPSS version 27 software. Before conducting multiple linear regression analysis, validity and reliability tests were first conducted to ensure that the instruments used were appropriate and consistent in measuring the variables studied. The analysis results show that the three independent variables—learning interest, learning discipline, and critical thinking skills—have a significant influence on student learning outcomes. Therefore, it can be concluded that improvements in these three aspects will positively impact student learning outcomes in the subjects studied.

Competition in Indonesia’s business world today compels companies to strategize in order to outperform their rivals. Only those companies that are truly strong, implement competitive strategies correctly, and carry out intensive promotions will succeed. One promotional tool that is expected to directly establish, improve, dominate, or maintain mutually beneficial exchange relationships with customers is personal selling, particularly aimed at encouraging consumers to purchase the offered products.A company’s goal is to obtain maximum profit from its business operations. To achieve this, managerial expertise and capability are required to combine the functions within the company effectively. Personal selling is carried out by the company to introduce its products, influence and inform consumers, so they are encouraged to buy—ultimately increasing sales volume.This study seeks to examine whether personal selling has a significant impact on increasing sales volume at PT. Intermas Tata Trading, Surabaya branch. A qualitative approach is used, supported by both qualitative and quantitative data from the company. Data collection techniques include editing, tabulating, and interviews. Data processing involves simple correlation analysis, simple regression analysis, and t-tests. Hypothesis testing is conducted using statistical analysis with SPSS 16.0.The study results confirm that the hypothesis is true: the personal selling variable (X) has a significant influence on the sales volume (Y) at PT. Intermas Tata Trading, Surabaya. This is evidenced by the t-value (4.005) > t-table (2.228) at a significance level of 0.002. The simple correlation coefficient is 0.785 or 78.5%, indicating a very strong and positive relationship between the independent variable (personal selling) and the dependent variable (sales volume).

Employee performance is a critical determinant of service quality and operational success in hospitals. High-performing employees contribute directly to patient satisfaction, service efficiency, and overall institutional reputation. This study investigates the influence of intrinsic and extrinsic motivation on the performance of employees at Petrokimia Gresik Hospital, aiming to provide empirical evidence to guide strategic human resource management in healthcare settings. A quantitative research design was employed, with data collected using structured questionnaires. The respondents consisted of 85 permanent employees selected through simple random sampling, ensuring that the sample fairly represented the hospital's workforce. The questionnaire was designed to measure aspects of both intrinsic motivation (such as self-fulfillment, recognition, and meaningful work) and extrinsic motivation (such as salary, benefits, and job security), along with indicators of employee performance. Data were analyzed using multiple linear regression analysis to examine the individual and joint effects of the motivational variables on performance. The results revealed that both intrinsic motivation (β = 0.532, p < 0.05) and extrinsic motivation (β = 0.487, p < 0.05) had a statistically significant and positive impact on employee performance. The model showed that the combination of these two factors accounted for 68.2% of the variation in employee performance (R² = 0.682), indicating a strong explanatory power. These findings underscore the importance of a balanced motivational strategy in hospital management. Relying solely on financial incentives is insufficient; efforts must also be made to cultivate a positive and fulfilling work environment. Therefore, hospital administrators are encouraged to design integrated motivation programs that address both intrinsic and extrinsic factors to enhance employee engagement, productivity, and ultimately, the quality of healthcare services provided.

This research is motivated by the low level of taxpayer compliance in paying Land and Building Tax (PBB) in Ngronggot District, Nganjuk Regency. This compliance problem is indicated by the high rate of delays and non-compliance in paying tax obligations, which is largely caused by weak enforcement of sanctions, low taxpayer awareness, and diverse economic conditions of the community. This study aims to analyze the influence of tax sanctions, taxpayer awareness, and economic level on compliance in paying PBB. The research method used is a quantitative approach with a survey technique, through the distribution of questionnaires to 100 taxpayer respondents selected using a simple random sampling technique. The data obtained were analyzed using multiple linear regression, accompanied by classical assumption tests such as normality tests, multicollinearity, heteroscedasticity, and hypothesis tests (t-test and F-test) to examine the influence of independent variables partially and simultaneously on the dependent variable. The results of the study indicate that partially, tax sanctions, taxpayer awareness, and economic level have a positive and significant influence on taxpayer compliance in paying PBB. Simultaneously, these three variables are also proven to have a significant influence on taxpayer compliance. These findings provide an important contribution to the formulation of regional fiscal policies, particularly regarding strategies for increasing regional tax revenue. Practical implications of this research include the need to increase the effectiveness of sanction enforcement, intensify tax outreach and education, and improve tax administration services to encourage public awareness and compliance. With the right strategies, it is hoped that taxpayer compliance will increase sustainably and contribute to optimizing regional revenue.

Indonesia ranks fourth globally in terms of active Instagram users, with approximately 103 million users, positioning this platform as a strategic medium for hospitals to conduct promotion, health education, and audience engagement. Hospitals, particularly private institutions, have increasingly recognized the potential of social media in fostering strong brand images and maintaining public trust. This study aims to analyze the influence of marketing content on the brand image of Indriati Solo Baru Hospital, a private hospital that is active on Instagram and holds verified status. Employing a quantitative approach with an associative method, the research involved 100 respondents drawn from followers of the hospital’s official Instagram account, selected through incidental sampling. Data were collected via questionnaires and subsequently analyzed using simple linear regression. The results demonstrate that marketing content exerts a positive and significant impact on brand image, as reflected in the regression equation Y = 3.838 + 0.267X. Statistical analysis further revealed a significance value of 0.001 (<0.05) and a t-calculated score of 10.048, exceeding the t-table value of 1.984. The coefficient of determination (R²) was 0.507, indicating that marketing content accounts for 50.7% of the variance in brand image, while the remaining 49.3% is influenced by other factors beyond the scope of this study. Among the tested indicators, Decision Making and Life Factors demonstrated significant contributions, underscoring their role in shaping perceptions of brand image. Meanwhile, Persuasion, Reader Cognition, and Sharing Motivation functioned as supportive elements that reinforce but do not independently drive outcomes. These findings highlight the critical role of strategic content development in strengthening hospital brand image within digital spaces.

This study aims to analyze the influence of the school environment and family environment on the learning interest of 8th-grade students at SMPN 1 Pangkalanbaru. Learning interest plays a crucial role in shaping students' academic performance and motivation. A conducive environment, both at school and at home, is believed to significantly contribute to the development of students' enthusiasm for learning. This research employed a quantitative method with a descriptive approach and utilized multiple regression analysis techniques to test the hypotheses. Data were collected through structured questionnaires distributed to 149 students from the 8th grade. The findings indicate that both the school and family environments have a positive and significant impact on students' interest in learning. The school environment's influence was confirmed by a simple linear regression coefficient of 0.229, while the family environment showed a stronger effect with a regression coefficient of 0.355. When tested simultaneously, both variables contributed to a combined effect on students' learning interest, with an R² value of 0.263, indicating that 26.3% of the variance in learning interest can be explained by these two factors. The remaining 73.7% is influenced by other variables not examined in this study, such as peer influence, personal motivation, teaching methods, and access to learning resources. These results underscore the importance of providing a supportive and engaging environment at both school and home to enhance students’ academic motivation. It is recommended that schools foster a positive atmosphere through effective teacher-student interactions, while families are encouraged to actively support their children's learning routines and emotional well-being. Further research is needed to explore other contributing factors and to develop holistic strategies that promote learning interest among junior high school students.

This study investigates the correlation between mental health and turnover intention among working students at STIE IBMI Medan who fulfill dual roles as both students and employees. These individuals are particularly vulnerable to psychological stress arising from academic responsibilities and workplace demands. The objective of this research is to examine the influence of mental health on their tendency to resign from their jobs. An associative quantitative research method was adopted, with data collected through structured interviews involving 71 respondents. The analysis was conducted using simple linear regression via the SPSS application. The findings reveal that mental health has a significant negative effect on turnover intention, with a significance value of 0.001. This suggests that students who experience better mental health are less likely to consider leaving their jobs. The coefficient of determination (R Square) is 14.6%, indicating that mental health explains 14.6% of the variation in turnover intention. The remaining 85.4% may be attributed to other contributing factors, such as high work pressure from supervisors, poor work-life balance, financial stress, inflexible schedules, and lack of organizational support. The implication of these results is that efforts to support and maintain the psychological well-being of working students are essential for reducing employee turnover. Educational institutions and employers should collaborate to create supportive environments through counseling services, flexible scheduling, mental health awareness programs, and policies that accommodate the dual responsibilities of student workers. By addressing these mental health concerns, institutions can improve student performance and job retention simultaneously. This study highlights the importance of integrating mental health strategies in workforce and academic management, especially for populations that manage competing academic and professional obligations.

The population used in this study is all breeders in Nagan Raya Regency, each farm has different abilities and number of livestock. Therefore, the population used is all farmers with an intensive maintenance system in 5 sub-districts of Nagan Raya Regency, namely 12 chicken farmers. Because of the small number of populations, the sample in this study is the entire population. The data sources in this study consist of primary data and secondary data. In this study, quantitative analysis uses  the Statistical Product and Service Solution (SPSS) version 26 computer program, because with this program analysis can be carried out quickly, and produce more accurate outputs. And the data analysis model used in this study is a simple linear regression method. The results of this study are that intensive maintenance costs incurred by broiler farmers have a very good influence on increasing profits from farmers' crops. Because with an intensive system the growth of chickens is more uniform and the deaths that occur in broilers can be avoided.

Every air traveler needs to understand the importance of dangerous goods. By understanding the nature and risks of these items, precautions can be taken to prevent accidents and ensure safe travel for all. In practice, numerous passengers have experienced delays at security checkpoints due to carrying prohibited or restricted items such as lighters, sharp tools like scissors, aerosols, and high-capacity power banks. These incidents not only disrupt airport operations but also highlight gaps in public awareness regarding aviation safety regulations.This study aims to examine the influence of knowledge about dangerous goods on flight safety, with a focus on passengers traveling through El-Tari Airport in Kupang, East Nusa Tenggara. A quantitative research method was employed by distributing 100 structured questionnaires to respondents using purposive sampling, targeting passengers with prior flight experience. Data analysis techniques included simple linear regression, T-tests, and the coefficient of determination (R²) to assess the relationship between knowledge levels and safety behavior. The findings show that knowledge about dangerous goods (variable X) significantly influences passenger safety behavior (variable Y), evidenced by a p-value of 0.000. This indicates a strong and positive correlation, where better knowledge leads to more responsible behavior during air travel. The R-square value of 0.530 suggests that 53% of variations in safety behavior can be explained by knowledge, while the remaining 47% may be influenced by other factors such as attitudes, past experiences, signage visibility, and staff communication.These findings underscore the urgent need for intensified public education efforts at airports through visual campaigns, digital information, and pre-flight reminders. Improving passenger knowledge about dangerous goods can significantly enhance overall flight safety and reduce the risk of delays or violations. Future research could explore the role of demographic factors or the effectiveness of current educational strategies.
