Abstract

The purpose of this research is to determine: (1) The combined influence of learning interest and discipline on mathematics learning achievement. (2) The influence of students' learning interest on mathematics learning achievement. (3) The influence of discipline on mathematics achievement. The method used is a survey method. The total population in this study consists of 600 students, and the sample taken for this research is 10% of the population, which is 60 students. The results of hypothesis testing indicate: (1) There is a significant combined influence of learning interest and discipline on mathematics learning achievement. This is evidenced by the significance value of 0.000 < 0.05 and an F value of 27.097. (2) There is a significant influence of learning interest on mathematics achievement. This is evidenced by the significance value of 0.000 < 0.05 and a t value of 5.544. (3) There is a significant influence of discipline on mathematics learning achievement. This is evidenced by the significance value of 0.035 < 0.05 and a t value of 2.155. This research is valuable for enhancing the quality of teaching and the mathematics learning achievement of students in a Private Vocational School in Central Jakarta.

Abstract

Education plays a central role in nation-building, with Vocational High Schools (SMK) in Indonesia holding a crucial role in providing skilled workforce. This article analyzes the policy of the Center of Excellence Vocational High School Program (SMK PK) using the Context, Input, Process, Product (CIPP) approach and a qualitative research method through library research analysis. The evaluation is based on legal foundations, objectives, curriculum implementation, resources, learning processes, and the impact of the SMK PK program. Context analysis reveals a strong legal foundation, yet improvement is needed in socialization and training. Input evaluation appreciates an industry-aligned curriculum design, although challenges persist in human resources and infrastructure. The curriculum implementation process shows progress, but coordination and synchronization need enhancement. Overall, the SMK PK program has a positive impact, improving graduate quality and fostering synergy between SMK, industry, and government. Challenges such as assistance focus, job market mismatch, and a lack of productive subject teachers require further attention. In conclusion, a comprehensive evaluation of the SMK PK program provides a complex overview, highlighting the potential to enhance vocational education quality in Indonesia.

Abstract

This study aims to analyze the influence of transformational leadership on teacher work productivity, both di-rectly and indirectly through work motivation. A quantitative approach was employed using path analysis based on Structural Equation Modeling (SEM) with SmartPLS 4. The population in this study consisted of civil servant elementary school teachers in Tasikmalaya Regency. The results revealed that transformational leadership sig-nificantly influenced teachers' work motivation, with a path coefficient of 0.919 and a p-value of 0.000. Trans-formational leadership also had a significant effect on teacher productivity both directly (coefficient 1.018; p-value 0.000) and in total effect (coefficient 0.954; p-value 0.000). However, work motivation did not have a sig-nificant impact on teacher productivity (coefficient -0.069; p-value 0.815), nor did it serve as a significant media-tor between transformational leadership and teacher productivity. These findings suggest that strengthening transformational leadership practices directly contributes more to improving teacher productivity than relying on motivational pathways.
