Abstract

Purpose – This research aims to develop a daily test instrument for clutch system material that is valid, reliable, and has good question item characteristics for students of the Automotive Engineering Education Study Program, Universitas Negeri Semarang.Methodology – The research method used is R&D with the ADDIE model. The test subjects in this study comprised 38 students selected through purposive sampling. Data were collected through a feasibility validation sheet completed by an expert validator and the results of student responses from the instrument trial, consisting of 10 multiple-choice questions. The analysis of empirical data included validity and reliability tests, level of difficulty, discriminative power, and distractor effectiveness.Findings – The results of the analysis showed that all 10 questions were declared empirically valid with values ranging from 0.594 to 0.877 (r_table = 0.329). The reliability coefficient of the instrument was obtained as (r_11) = 0.912 (very high category). The characteristics of the question items showed the proportion of the ideal difficulty level (50% easy, 40% medium, and 10% difficult), the effectiveness of the deceitful function was 83.33% (25 out of 30 deceitful), and the discriminating power was categorized as sufficient to very good (3 adequate, 4 good, and 3 very good).Contribution – This study contributes to the development of a daily test instrument for clutch system material that has been proven to be valid, reliable, and to have good item quality for students of the Automotive Engineering Education Study Program, Universitas Negeri Semarang. The developed instrument can be used as an objective learning evaluation tool.

Abstract

Purpose – This study aims to analyze the influence of cognitive abilities in Mathematics, Indonesian Language, and English subjects on students’ Intelligence Quotient (IQ).Methodology – This study employed a quantitative approach using multiple linear regression analysis. The research data consisted of academic scores for 82 students across three subjects and their IQ scores. Prior to conducting the regression analysis, descriptive statistics and classical assumption tests were performed, including tests for normality, multicollinearity, and heteroscedasticity.Findings – The regression analysis results from the initial model indicated that Mathematics and Indonesian Language abilities had a positive and significant effect on students’ IQ. In contrast, English ability did not show a significant effect. Therefore, the regression model was simplified by including only the Mathematics and Indonesian Language variables. The final model analysis demonstrated that both variables continued to have a positive and significant effect on students’ IQ. The coefficient of determination indicated that the research model explained approximately 23.3% of the variation in students’ IQ.Contribution – The findings of this study indicate that numerical and verbal abilities help explain students’ cognitive abilities.

Abstract

Purpose - This study aims to analyze the leadership of school principals in building Child-Friendly Schools (CFS) based on organizational culture in elementary schools.Methodology - The study employed a qualitative approach using a case study design at SDN Sungai Miai 10 and SDN Sungai Miai 11 in Banjarmasin. Data were collected through interviews, observations, and documentation involving principals, teachers, students, and educational staff. Data analysis used the interactive model of Miles, Huberman, and Saldana, while data validity was ensured through triangulation of techniques, sources, and time.Findings - The findings revealed that principals acted as agents of organizational culture transformation through strengthening humanistic communication, teacher development, learning supervision, positive discipline, and the habituation of child-oriented school culture. The implementation of a child-friendly organizational culture was reflected in the development of dialogic communication, increased student participation, reduced verbal violence, and more open social relationships between teachers and students. However, the implementation had not yet been fully optimal due to the influence of old cultural patterns, differences in teachers’ understanding, and limitations in strengthening the school institutional system.Contribution - This study concludes that the success of CFS transformation, based on organizational culture, is strongly influenced by the effectiveness of principals’ leadership in continuously internalizing child-friendly values within school culture.
