Abstract

The low level of students' critical thinking skills is one of the main challenges in education, often caused by a lack of variety in instructional models. To address this issue, the researcher implemented the Problem-Based Learning model integrated with Science, Technology, Engineering, and Mathematics (PBL-STEM). This study aims to examine the effect of the PBL-STEM model on students' critical thinking skills. The research employed a nonequivalent control group design, involving two groups of students: an experimental group taught using the PBL-STEM model and a control group taught using the conventional PBL model. The subjects were Grade 10 science students (X MIPA) at a senior high school. Data were collected through a critical thinking skills test consisting of 10 validated essay questions, with a reliability coefficient of 0.649. The results indicate that the application of the PBL-STEM model effectively enhances students’ critical thinking skills, with an N-Gain score of 72%, categorized as high. The most significant improvement was observed in the indicators of elementary clarification (the ability to understand and clarify basic concepts) and inference (the ability to draw logical conclusions). A significance test revealed a statistically significant difference between the experimental and control groups, confirming that the PBL-STEM model has a substantial impact on developing students' critical thinking skills.. These findings suggest that the PBL-STEM model not only strengthens students’ analytical and logical reasoning but also provides a learning experience that is relevant to real-world contexts. The study recommends the implementation of the PBL-STEM model as an innovative teaching method to foster critical thinking skills, particularly within science and technology-based learning environments.

Abstract

This research was conducted at PT Tri Jaya Teknik Karawang to analyze the constraints in making trial part action bracket support using SPHC T=3.2 material.  This research is important because the trial part process is a crucial stage in ensuring production efficiency and product quality before entering the mass production stage, this research can reveal the root causes of defects, determine the main risk factors, and provide effective improvement recommendations. By applying the FMEA method, companies can reduce product defect rates, improve production efficiency, and optimize the use of resources. The Failure Mode and Effects Analysis (FMEA) method and fishbone diagram are used to identify failures, causes, and determine the highest failure value. This research plays a role in improving production efficiency by reducing the number of defective products that can cause waste of cost and time. The results show that the failures that have the highest Risk Priority Number (RPN) value are thread damage and off-center hole position with an RPN value of 180. Fishbone diagrams identify the main factors causing failures which include tapping, drilling, bending, and operators.

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui pengaruh E-LKPD berbasis model CLIS terhadap keterampilan berpikir kritis pada bahasan momentum dan impuls. Metode penelitian yang digunakan kuasi eksperimen dengan desain penelitian posttest only control design. Populasi penelitian ini seluruh kelas X IPA di SMAN 2 Ciamis dengan jumlah siswa 250 orang sebanyak 7 kelas. Sampel penelitian diambil dengan teknik cluster random sampling sebanyak 2 kelas, yaitu kelas X IPA 5 sebagai kelas eksperimen dan kelas X IPA 3 sebagai kelas kontrol, dengan rincian masing-masing kelas berjumlah 36 peserta didik. Instrumen pengumpulan data adalah tes yang berbentuk soal uraian. Teknik analisis data menggunakan uji prasyarat (uji normalitas, uji homogenitas), dan uji hipotesis. Hasil uji hipotesis pada taraf signifikansi (???? = 0,05) menunjukkan bahwa diperoleh thitung(7,86) > ttabel(1,67) sehingga Ha diterima. Ini berarti ada pengaruh E-LKPD berbasis model Children Learning In Science terhadap keterampilan berpikir kritis pada pokok bahasan momentum dan impuls di kelas X IPA SMA Negeri 2 Ciamis tahun ajaran 2022/2023.
