Abstract

Penelitian ini bertujuan untuk menganalisis penerapan Keselamatan dan Kesehatan Kerja (K3) pada pekerja bagian produksi di Section Mill PT Krakatau Baja Konstruksi. Permasalahan utama yang diangkat adalah rendahnya kepatuhan pekerja terhadap penggunaan alat pelindung diri (APD), seperti masker dan earplug. Meskipun secara struktural perusahaan telah memiliki sistem K3. Penelitian ini menggunakan metode studi kasus dengan pendekatan kualitatif melalui observasi langsung dan wawancara dengan karyawan dan Ketua Manajemen K3. Hasil penelitian menunjukkan bahwa sebagian besar pekerja mematuhi penggunaan APD dasar seperti helm, sepatu safety, dan wearpack, namun masih mengabaikan penggunaan beberapa APD. Faktor penyebabnya antara lain ketidaknyamanan saat menggunakan APD, keterbatasan ketersediaan alat, dan lemahnya pengawasan. Meskipun fasilitas pendukung seperti P3K dan alat kerja dalam kondisi baik telah tersedia, efektivitas penerapan K3 belum optimal. Penelitian ini merekomendasikan peningkatan pelatihan, penyediaan APD yang lengkap, serta penguatan pengawasan dan budaya keselamatan kerja guna meminimalkan risiko kecelakaan dan gangguan kesehatan di tempat kerja.

Abstract

This study aimed to develop and validate the quality of a multiple-choice instrument for measuring fifth-grade elementary students' understanding of kinetic-to-electrical energy conversion concepts within a STEAM (Science, Technology, Engineering, Arts, and Mathematics) framework. The research employed a Design and Development Research (DDR) approach with systematic instrument development procedures comprising: literature review and blueprint development, item construction, expert validation, field testing with 28 fifth-grade students, and comprehensive psychometric analysis. The instrument consists of 20 multiple-choice items covering three knowledge dimensions: conceptual (5 items), procedural (10 items), and applicative (5 items). Content validity was established through expert review by three science education specialists, yielding a Content Validity Index (CVI) of 0.87. Item analysis revealed difficulty indices ranging from 0.35 to 0.85 (predominantly moderate difficulty) and discrimination indices ranging from 0.30 to 0.75 (good to excellent discrimination). Reliability analysis using Cronbach's alpha produced a coefficient of 0.82, indicating high internal consistency suitable for elementary school assessment contexts. The instrument demonstrates satisfactory psychometric properties aligned with standards for elementary science assessment and effectively integrates STEAM pedagogical approaches.

Abstract

The Making Indonesia 4.0 program requires an educational system that fosters transdisciplinary, contextual, and practical learning to improve technical literacy and promote environmental sustainability. This study is aimed to assess the effectiveness of STEAM-based pre-vocational experiential learning in improving the cognitive abilities of primary school children. This study employed a quantitative, quasi-experimental One-Group Pretest-Posttest design. The study involved 27 fifth-grade primary school students selected through a purposive sampling technique. The results showed that the average pre-test score for students was 54.70, and most of them fell into the medium range (51–75). After STEAM-based learning was put into place, the average score on the post-test went up to 72.66, and most students moved up to the high group (76–100). According to Hake's criteria (1999), the N-Gain analysis showed an average value of 0.40, which means it was moderate. The Paired Sample t-Test also showed a significance value of p = 5.75 × 10⁻⁷ (0.05), which means that the learning outcomes improved in a statistically significant way. Thus, it can be deduced that STEAM-oriented pre-vocational experiential learning is comparatively beneficial in augmenting students' cognitive abilities. This method positively influences learning outcomes descriptively and is empirically validated, rendering it pertinent for use as a contextual learning technique to enhance 21st-century capabilities in primary education.

Abstract

The inclusion of Science, Technology, Engineering, Arts, and Mathematics (STEAM) education in the elementary level has been seen as a crucial part in the development of 21st-century skills and prevocational developments of elementary students. This study aims to find out the effectiveness of a hands-on motion-to-electricity learning module in enhancing STEAM skills of 5th-grade elementary students using a one-shot quasi-experimental design. The participants consisted of 28 fifth-grade students from a primary school in the Banten province. To demonstrate the conversion of kinetic energy into electrical energy, the students built simple wheel generator sets using bicycle dynamos, wires, rotating wheels, and LED lights. Immediately after the activity, a 15-item validated evaluation form was employed to collect data, focusing on the principles of energy conversion, concepts of renewable energy, and simple engineering knowledge. Based on the statistical analysis, 82.1% of the students achieved beyond the required level of proficiency, scoring a mean of 67.25 and a standard deviation of 16.34. The findings of the observation conclusion revealed that the students exhibited a positive attitude towards technical subjects, were actively engaged in their learning process, and worked together to overcome problems. The findings of the study's conclusion indicate that interactive STEAM educational materials can be a valuable tool in increasing the interest of primary school students in technical subjects and their understanding of energy conversion concepts. This study supports the use of hands-on learning approaches in elementary STEAM education as a foundation for future prevocational and technical education.

Abstract

This study examined the effectiveness of STEAM pre-vocational learning in terms of the development of students’ psychomotor skills and affective attitudes. The study employed a descriptive quantitative approach with a project-based observation method among 23 fifth-grade students at an elementary school in Indonesia. The learning process was developed based on a Mini Solar Panel House project, which was an authentic pre-vocational learning task that integrated science, technology, engineering, art, and mathematics. The data were gathered using a validated process observation tool, which had content validity confirmed by Aiken’s V-value ( 0.75) and high internal consistency for both psychomotor (α = 0.87) and affective (α = 0.84) dimensions. The psychomotor dimension included four components: work safety, work preparation, work procedure, and presentation of results, while the affective dimension included responsibility, teamwork, communication, and discipline. The findings indicated that students demonstrated high performance in both dimensions with a mean score of 1.80 for psychomotor skills and 1.78 for affective attitudes on a 2.00-point scale. The highest achievements were obtained in work procedure (M = 1.90) and discipline (M = 1.93), while presentation skills (M = 1.70) and teamwork (M = 1.60) were relatively lower. The Pearson’s correlation analysis showed a strong positive correlation between the psychomotor and affective areas (r = 0.76, p 0.01), with the highest correlation between work procedure and discipline (r = 0.81). The findings of this study show that STEAM-based pre-vocational learning is an effective approach to support the integrated development of technical competencies and work-related attitudes, as measured by process-based assessment. This study adds to the existing literature on STEAM by providing empirical insights into the integration of psychomotor and affective areas in early pre-vocational settings. It has implications for the development of holistic and project-based learning models.
