Abstract

This study aims to analyze the influence of the learning environment, lecturer knowledge, and personal initiative on the learning process and graduate quality in higher education institutions. The methodology employed is Structural Equation Modeling (SEM) to test the relationships among these variables. The results indicate that a conducive learning environment and adequate lecturer knowledge significantly contribute to the learning process. Additionally, students’ personal initiative also positively impacts graduate quality. These findings provide essential insights for educational managers to create a better learning environment and enhance teaching quality in efforts to improve graduate outcomes.

Abstract

Rapid advances in wireless communication systems have increased the demand for compact and efficient antennas. This study presents the design and analysis of miniature microstrip antennas intended for applications in L-band frequencies. The antenna structure is based on a rectangular patch with modifications in the form of U-shaped slot (MRDPU) and L- shaped slot (MRDPL) configurations that aim to reduce the size of the antenna without sacrificing performance. The proposed antenna operates in the frequency range of 1,064 GHz to 1,562 GHz, with significant improvements in return loss values, bandwidth, and overall efficiency. Comparative analysis shows that the design with U-shaped slots (MRDPU) provides better miniaturization and performance compared to L-shaped slot designs (MRDPL). The U- shaped slot design achieves a return loss of -11.15 dB at 1.064 GHz, while the L-shaped slot design has a return loss of -10.907 dB at 1.206 GHz. Both configurations offer an effective solution for L-band frequency applications. The study highlights the potential of slot-based modifications in achieving antenna miniaturization without sacrificing important performance parameters.

Abstract

This research aims to evaluate the influence of lecturer knowledge and personal initiative on improving learning outcomes and graduate quality in higher education institutions. Utilizing Partial Least Squares Structural Equation Modeling (PLS-SEM), this study examines the relationships between these variables based on data collected from faculty members and student performance records over a 12-month period. The analysis reveals a significant positive effect of both lecturer knowledge and personal initiative on student learning outcomes and the overall quality of graduates. These findings suggest that targeted faculty development programs can play a critical role in enhancing educational quality and institutional reputation.

Abstract

Creative thinking is a crucial competency in vocational education, especially in facing the challenges of the dynamic aviation industry. This study aims to analyze the factors that influence the improvement of creative thinking skills of vocational education students at the Surabaya Aviation Polytechnic. This study uses a quantitative approach to analyze the relationship between variables, with a sample of 100 students taken using a simple random sampling technique from a population of 525 Vocational Education students at the Surabaya Aviation Polytechnic. Data were collected through questionnaires and then analyzed using Multiple Linear Regression using SPSS 22 software. The results showed that Intrinsic Motivation Factors, Innovative Teaching Method Factors, and Industry Support Factors had a significant influence on students' creative thinking skills, while Learning Environment Factors did not have a significant effect. The Adjusted R Square determination coefficient of 0.687 indicates that 68.7% of the variation in creative thinking skills can be explained by the independent variables in the model, with the remaining 31.3% explained by other factors outside the model.
