Abstract

Abstrak Pendidikan di indonesia saat ini lebih menitikberatkan pada hasil belajar peserta didik. Model pembelajaran yang diterapkan guru dalam proses pembelajaran dalam kelas berpengaruh terhadap hasil belajar peserta didik. Di Indonesia sendiri terdapat berbagai model pembelajaran dengan berbagai keunggulan dan kekurangan, salah satunya model pembelajaran inovatif seperti Discovery Learning. Tujuan dari kajian pustaka ini mengulas pengaruh penggunaan model Discovery Learning terhadap hasil belajar peserta didik. Teknik pengumpulan data pada ulasan ini dikaji berdasarkan fokus model pembelajaran dengan mendeskripsikan secara singkat artikel tersebut kemudian ditarik kesimpulan. Jadi metode pada kajian ini, lebih ditekankan studi terpenting dan terkini dari literatur yang membahas model Discovery Learning. Proses pembelajaran dapat dipengaruhi oleh berbagai faktor, antara lain cara belajar, guru, kurikulum, metode, model dan pendekatan yang digunakan selama proses pembelajaran. Hasil kajian beberapa literatur diperoleh data bahwa model Discovery Learning dapat meningkatkan hasil belajar melalui keaktifan peserta didik dalam proses pembelajaran yang berdampak positif  terhadap  hasil belajar peserta didik.

Abstract

This qualitative study focuses on occupational safety and health in vocational school machining workshops to identify significant risks related to training practices. Workplace accidents are considered a serious threat to workers and equipment, potentially affecting productivity and environmental safety. Observations at several vocational schools, especially at SMK Negeri 1 Batipuh, showed low student awareness and compliance with OHS regulations, increasing the risk of risky behaviour and accidents. To address this, the research used the Hazard Identification, Risk Assessment, and Risk Control (HIRARC) method, which systematically identifies hazards, evaluates risks based on severity and likelihood, and proposes control measures. The research at SMK Negeri 1 Batipuh involved direct observation, interviews, and analysis of SOPs in the workshop, finding significant risk variations in workshop conditions, lathe operations, welding, material handling, hand tool use, and machine protection. The results highlighted the predominance of intermediate risks in all-hazards analyzed, emphasizing the importance of developing more effective risk management strategies. This research aims to reduce accidents and improve student safety during training by addressing existing OHS implementation gaps and implementing appropriate risk controls. In addition to filling a gap in the literature, this study provides practical insights for improving OHS practices in vocational schools.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh pemanfaatan Discord sebagai portal pembelajaran terhadap minat belajar siswa pada mata pelajaran Gambar Teknik Manufaktur di SMK Negeri 1 Padang. Penelitian menggunakan pendekatan kuantitatif dengan desain quasi experiment berbentuk posttest-only control group design. Sampel penelitian terdiri atas 60 siswa kelas XI Teknik Pemesinan yang terbagi ke dalam kelompok eksperimen dan kelompok kontrol. Kelompok eksperimen mengikuti pembelajaran menggunakan Discord sebagai portal pembelajaran, sedangkan kelompok kontrol menggunakan pembelajaran konvensional. Pengumpulan data dilakukan melalui angket minat belajar siswa yang telah diuji validitas dan reliabilitasnya. Data dianalisis menggunakan statistik deskriptif dan uji independent sample t-test. Hasil penelitian menunjukkan bahwa pemanfaatan Discord sebagai portal pembelajaran berpengaruh signifikan terhadap minat belajar siswa, dengan nilai signifikansi 0,000 (<0,05). Temuan ini mengindikasikan bahwa integrasi Discord dalam pembelajaran mampu meningkatkan keterlibatan dan ketertarikan siswa dalam pembelajaran Gambar Teknik Manufaktur.

Abstract

Stainless steel 304 (SUS 304) is widely used for food containers because of its corrosion resistance and suitability for food-contact applications. However, the occurrence of denting, wrinkling, and permanent deformation in some products suggests possible variations in material quality and mechanical performance. This study compared the chemical composition and mechanical properties of two types of SUS 304 food containers, designated Type 1 and Type 2. Chemical composition was determined using optical emission spectroscopy, while mechanical properties were evaluated through tensile testing in accordance with ASTM E8/E8M and deflection testing using the three-point bending method. The evaluated parameters comprised yield strength, ultimate tensile strength, elongation, maximum force, deflection modulus, and deflection strength. Chemical analysis confirmed that all specimens satisfied the compositional requirements for stainless steel 304 specified in ASTM A240. The mechanical test results showed that Type 1 specimens had greater tensile strength than Type 2 specimens. Type 1 also exhibited higher deflection modulus and deflection strength, although Type 2 recorded a slightly higher average maximum force. These findings indicate that Type 1 food containers possess greater stiffness and resistance to deformation and therefore demonstrate superior overall mechanical quality compared with Type 2 products. The study provides an evidence-based framework for evaluating material performance and strengthening quality-control procedures for SUS 304 food containers.

Abstract

Unemployment among educated individuals indicates that higher education institutions need to equip students not only with readiness to enter the workforce but also with the ability to create employment opportunities. However, research simultaneously examining Praktik Lapangan Industri experience and entrepreneurial understanding as predictors of entrepreneurial interest among mechanical engineering students remains limited. This study aimed to analyze the effects of Praktik Lapangan Industri experience and entrepreneurial understanding on students’ entrepreneurial interest. The study employed a quantitative approach with a correlational design. The respondents consisted of 78 students from the Department of Mechanical Engineering at Universitas Negeri Padang from the 2021–2023 cohorts, selected using total sampling. Data were collected through a Likert-scale questionnaire and analyzed using multiple linear regression, t-tests, an F-test, and the coefficient of determination with SPSS. The results yielded the regression equation Y = −37.910 + 0.786X₁ + 1.046X₂. Praktik Lapangan Industri experience and entrepreneurial understanding were positive and significant predictors of entrepreneurial interest, both partially and simultaneously. The two variables explained 60.6% of the variation in entrepreneurial interest, while the remaining 39.4% was associated with other factors not included in the research model. Entrepreneurial understanding made a more dominant contribution than Praktik Lapangan Industri experience. These findings confirm the importance of integrating industrial experience and entrepreneurship education in fostering entrepreneurial interest among mechanical engineering students. In practical terms, higher education institutions need to strengthen entrepreneurship education and orient Praktik Lapangan Industri toward developing business management competencies.
