Abstract

This research aims to identify the planning implementation, idenfety Management System (SMK3) at the workshop of vocational high schools in the major of construction and property engineeringtify the implementation, and identify the evaluation of the implementation of the Occupational Health And Safety Management System (SMK3) at the workshop of Construction and Property Engineering Study Program, one of the Vocational High Schools in Central Java. This research is qualitative by using data collection techniques in interviews, observations, and documentation the validity of the data using source triangulation. Data analysis used descriptive qualitative. The results show that the workshop building at one of the Vocational High Schools in Central Java has been well planned in its implementation of OHS. The implementation of OHS is categorized as quite well implemented. The evaluation of the implementation of OHS is categorized as quite well done. Hence, the Occupational Health and Safety (OHS) management system at the Vocational High Schools needs to be improved. The school can collaborate with stakeholders to follow up on the management system of OHS.

Abstract

This study addresses the need for instructional approaches that integrate conceptual understanding with collaborative competencies in 21st-century education. Specifically, it examines the effects of experiential learning on students' conceptual understanding and collaborative skills concerning Systems of Linear Equations in Two Variables (SLETV). A quasi-experimental nonequivalent control group design was employed, involving 64 ninth-grade students divided equally into a control group (n = 32) and an experimental group (n = 32). Data were collected using a conceptual understanding test and a collaborative skills questionnaire, both of which demonstrated acceptable validity and reliability. Data analysis included independent-samples t-tests, paired-samples t-tests, and multivariate analysis of variance (MANOVA). The results indicated significant differences between the groups, with the experimental group exhibiting higher posttest scores in both conceptual understanding and collaborative skills. Furthermore, MANOVA confirmed a significant multivariate effect (Wilks' Lambda = 0.751, F = 10.090, p < 0.001), showing substantial improvements in both conceptual understanding (F = 19.766, p < 0.001) and collaborative skills (F = 4.408, p = 0.040). Ultimately, students who engaged in experiential learning outperformed their peers receiving conventional instruction. These findings highlight the efficacy of experiential learning in simultaneously fostering mathematical comprehension and collaborative competencies in junior high school mathematics.
