Abstract

Masih banyak siswa yang kesulitan dalam mencapai pembelajaran yang optimal pada mata pelajaran teknik pengelasan shield metal arc welding (SMAW). Selain itu, siswa juga kurang memahami bahan-bahan las busur, termasuk cara penggunaan alat dan cara penggunaannya. Penelitian ini memiliki tujuan mengetahui bagaimana media pembelajaran virtual reality (VR) mempengaruhi pengaruh belajar siswa pada mata pelajaran Teknik Pengelasan SMAW di Kelas XI SMK Negeri 5 Padang. Pengelasan VR digunakan sebagai media pembelajaran dengan menggunakan pendekatan kuantitatif dan desain quasi eksperimen. Penelitian ini melibatkan 1 kelas penelitian dan 1 kelas pemantauan, dengan jumlah siswa di kelas penelitian sebanyak 33 siswa dan kelas pemantauan berjumlah 34 siswa. Untuk mengetahui kemampuan keterampilan siswa, pengumpulan informasi dilakukan dengan menggunakan evaluasi pretest dan posttest. Selain itu dilakukan uji prasyarat guna menguji homogenitas dan normalitas data perolehan belajar siswa. Hasil eksperimen mengindikasikan bahwa uji t memunculkan nilai signifikansi dua sisi sejumlah 0,007 makin rendah daripada 0,05. Rata-rata persentase kelas penelitian sejumlah 80,06 dan rata-rata persentase kelas pengawasan sejumlah 75,88. Hal ini membuktikan bahwa pemanfaatan media pembelajaran virtual mampu mempengaruhi hasil belajar siswa kelas penelitian.

Abstract

This study explores the impact of parents' economic status on students' learning motivation at SMKN 1 Guguk. Education is the cornerstone of national development, and in Indonesia, educational success is determined not only by the quality of teaching but also by external factors such as parental economic status. The research reveals that family economic level plays a crucial role in students' access to educational facilities, which affects their learning motivation. Students from well-off families tend to have more learning tools and adequate support, whereas those from low-income families often lack essential facilities, impacting their motivation and academic performance. This study employs a descriptive method with a quantitative approach, involving 79 students as the sample. A questionnaire was used as the research instrument to measure the variables of parents' economic status and students' learning motivation. The analysis results show a significant correlation between economic conditions and students' learning motivation. These findings provide insights for educators, parents, and policymakers in designing effective strategies to enhance students' learning motivation, notably for those from economically disadvantaged families. The results are expected to improve the quality of education at SMKN 1 Guguk and serve as a basis for more inclusive and equitable educational policies in Indonesia.

Theì causeì of work accideìnts is baseìd on a lack of undeìrstanding in impleìmeìnting Occupational Safeìty and Heìalth (K3), as weìll as Occupational Safeìty and Heìalth (K3) reìgulations that areì not followeìd, theìreìforeì theì leìveìl of risk of accideìnts will beì veìry largeì. Theì purposeì of this study is to deìteìrmineì theì reìlationship beìtweìeìn occupational heìalth and safeìty (K3) and theì leìarning outcomeìs of meìchanical practiceì of gradeì XI studeìnts majoring in Meìchanical Eìngineìeìring at SMK Neìgeìri 1 Padang. Theì data colleìction teìchniqueì in this study useìs a queìstionnaireì with a likeìr scaleì. Theì data analysis teìchniqueì useìs SPSS softwareì with correìlation analysis that looks for variableì reìlationships. As a reìsult of theì data deìscription, a positiveì and significant reìlationship beìtweìeìn theì reìlationship beìtweìeìn theì impleìmeìntation of K3 and theì leìarning outcomeìs of Prakeìrin studeìnts in gradeì XI of Machining Eìngineìeìring SMK Neìgeìri 1 Padang was 0.490. at a significanceì leìveìl of 0.05 That this can proveì a positiveì influeìnceì beìtweìeìn theì two variableìs. Meìanwhileì, theì deìteìrminant valueì (R2) is 0.185. This meìans that theì reìlationship beìtweìeìn theì application of K3 and theì leìarning outcomeìs of latheì practiceì has a weìak cateìgory. From this, it can beì concludeìd that many factors affeìct theì impleìmeìntation of studeìnt K3, of which oneì of theìseì many things is studeìnt leìarning outcomeìs.

Abstract

The following study is intended to find if it exists an association among these application about K3 aspects along with student learning outcomes of the welding engineering workshop at SMK Negeri 1 Guguk. During the practice, it was found that there was a lack of understanding and implementation of K3 aspects by the Welding Technology students, as well as insufficient attention to and maintenance of K3 equipment. This research applies correlational methods with quantitative techniques. A total of 55 class XI TLAS students in the SMAW Welding Engineering subject were to be used as subjects. Sampling method adopted in this study is the purposive sampling technique. The data testing results in this study used the product-moment correlation, which showed that the calculated r score was higher than the table r value, indicating a positive relationship between the variables. The significance score was low, leading to the acceptance of the alternative hypothesis (Ha). Thus, the research hypothesis is recognized at a sufficient interpretation level. The data testing results show that the implementation of K3 aspects contributes to student learning outcomes, although the contribution is not dominant. Other aspects that influence student learning outcomes were not studied in this research. Outcome of the data examination lead to theconclusion that application about K3 aspects shows a direct impact on the results of learning of class XI Welding Engineering students in the manual arc welding subject at SMK Negeri 1 Guguk.

Abstract

The depletion of fossil energy reserves, especially oil and natural gas, has driven innovations in energy-efficient vehicles, including through the Energy-Efficient Car Contest (KMHE). In developing prototype cars for this competition, driver ergonomics is often overlooked. This study aims to analyze musculoskeletal complaints experienced by prototype car drivers from the Faculty of Engineering at UNP. The main instrument used was the Nordic Body Map (NBM) questionnaire, administered to three drivers after they performed a 20-minute static driving simulation. The collected data were analyzed and categorized based on complaint levels. The results showed that the most frequent complaints occurred in the lower back (score 12), followed by the lower neck, buttocks, and hips (score 11). The average overall score was 71.67, indicating a high-risk category. The highest individual score was 89 (Driver 3), and the lowest was 62 (Driver 1). These complaints were caused by the absence of an ergonomic driver seat in the prototype car. The study concluded that the current cockpit design is not ergonomically adequate, posing a risk of injury. Therefore, it is recommended that the design team immediately create a more upright driver seat with thigh support to enhance comfort and reduce musculoskeletal complaints.

Abstract

Penelitian ini bertujuan untuk menganalisis efektivitas penerapan sistem blok terhadap hasil belajar teori dan praktik pada mata pelajaran Teknik Pengelasan di SMK Negeri 2 Solok. Penelitian menggunakan pendekatan kuantitatif dengan desain Posttest-Only Nonequivalent Groups Design yang termasuk dalam quasi experimental. Populasi penelitian berjumlah 115 siswa kelas XI Teknik Pemesinan Tahun Ajaran 2025/2026 yang seluruhnya dijadikan sampel, terdiri atas 47 siswa kelas non blok dan 68 siswa kelas sistem blok. Data diperoleh melalui dokumentasi nilai hasil belajar teori dan praktik. Analisis data diawali dengan uji normalitas Kolmogorov–Smirnov, kemudian dilanjutkan dengan uji Mann–Whitney U dan Wilcoxon Signed-Rank Test karena data tidak berdistribusi normal, serta perhitungan effect size. Hasil penelitian menunjukkan bahwa rata-rata hasil belajar teori (82,25) dan praktik (83,27) pada kelas sistem blok lebih tinggi dibandingkan kelas non blok, masing-masing sebesar 77,35 dan 75,27. Uji Mann–Whitney U menunjukkan terdapat perbedaan yang signifikan pada hasil belajar teori maupun praktik (p = 0,001 < 0,05). Nilai effect size sebesar 0,523 pada teori dan 0,782 pada praktik menunjukkan kategori efek besar, sehingga dapat disimpulkan bahwa sistem blok efektif meningkatkan hasil belajar Teknik Pengelasan, terutama pada keterampilan praktik
