Abstract

The aims of this research include exploring the influence of laboratory management on the performance of managers (laboratories) at SMA IT Yarsi Mataram. This research uses a quantitative approach with a correlational type of research. The research method uses statistical research methods with an analytical design. The data collection technique uses observation, which consists of 1 independent variable, namely laboratory management, and 2 dependent variables, namely manager performance and science process skills. There are 2 instruments used, namely a questionnaire instrument for manager performance variables, and an assessment sheet for science process skills. The total population is 78 people, and the sample is 30 people. The research results show that, among other things, there is no influence of laboratory management on manager performance; this can be seen from the significance value obtained from the ANOVA test, namely 0.221, which is greater than the 5% significance level, namely 0.05. This means that the differences or variations in laboratory management are not strong enough to influence changes in manager performance. This could be caused by other factors outside of laboratory management that are more dominant in influencing performance, such as leadership style, organizational culture, work motivation, or the performance appraisal system used. The implication of this study is the importance of the laboratory as a place to develop students’ science skills practically. So, to provide maximum implementation, laboratory management is needed with laboratory assistants who have good performance, so that the final results in science learning can achieve the intended goals.

Abstract

This study was conducted with the aim of developing an effective and feasible e-learning-based chemistry textbook intended to enhance students’ critical thinking abilities. The development process adhered to the ADDIE model, providing a systematic framework for the design of educational materials. Participants in the study consisted of first-semester chemistry education students at the Faculty of Tarbiyah and Teacher Training, UIN Mataram. Data were collected using both test and non-test instruments. Non-test instruments were employed to evaluate the feasibility of the e-learning-based chemistry textbook, whereas test instruments were used to measure students’ critical thinking skills. The study was carried out in two primary stages: validation of the product and trials involving chemistry education students at UIN Mataram. For the trials, a quasi-experimental design with a pre-test/post-test control group was implemented. The results of the study led to the following conclusions: (1) The developed e-learning chemistry textbook attained validity scores ranging from 0.857 to 0.905, classifying it as very high, with a reliability coefficient of 0.865. These results indicate that the textbook is valid and reliable for use in Basic Chemistry courses at the tertiary level. (2) Analysis using an independent samples t-test revealed a significance value of 0.018, below the alpha threshold of 0.05, confirming that the e-learning chemistry textbook is effective in improving students’ critical thinking skills. Overall, the findings demonstrate that the developed e-learning-based chemistry textbook is both valid and reliable, and it effectively enhances students’ critical thinking abilities.
