Abstract

Penelitian ini bertujuan untuk melakukan analisis komparatif terhadap dua pendekatan analitik klasik, yaitu metode Rayleigh dan Dunkerley, dalam berasumsi frekuensi alami sistem poros berputar dengan dua cakram simetris. Evaluasi dilakukan untuk menilai seberapa akurat kedua metode tersebut jika dibandingkan dengan hasil simulasi numerik berdasarkan metode elemen hingga. Perhitungan analitik dilakukan berdasarkan parameter geometri dan sifat mekanik poros baja AISI 4140, serta konfigurasi massa cakram yang umum digunakan pada alat praktikum putaran kritis. Selanjutnya, hasil estimasi frekuensi alami dari masing-masing metode divalidasi melalui simulasi numerik menggunakan perangkat lunak ANSYS Workbench dengan prosedur modal analysis . Hasil menunjukkan bahwa metode Rayleigh memberikan estimasi frekuensi alami sebesar 80,58 Hz, dengan deviasi kurang dari 0,1% terhadap hasil simulasi numerik sebesar 80,495 Hz. Sementara itu, metode Dunkerley menghasilkan estimasi sebesar 79,11 Hz, yang menunjukkan deviasi lebih besar. Temuan ini menunjukkan bahwa metode Rayleigh memiliki tingkat akurasi yang lebih tinggi dan dapat dijadikan sebagai pendekatan awal yang Andal dalam proses perancangan sistem poros dinamis, khususnya pada tahap awal analisis sebelum dilakukan simulasi numerik lanjutan.

Abstract

Rangka tubular merupakan komponen utama pada kendaraan off-road tipe buggy yang berfungsi sebagai penopang beban statis dan dinamis serta menentukan keselamatan pengemudi dan performa kendaraan. Penelitian ini bertujuan untuk menganalisis pengaruh beban benturan depan (frontal) dan benturan samping (lateral) terhadap kinerja struktural rangka tubular buggy menggunakan Metode Elemen Hingga (Finite Element Method/FEM) dengan bantuan perangkat lunak ANSYS Workbench. Variasi material yang digunakan meliputi baja karbon AISI 1018, baja ASTM A572 Grade 50, dan aluminium 6061 dengan variasi geometri diameter dan ketebalan pipa. Parameter yang dianalisis meliputi deformasi total, tegangan Von Mises, dan faktor keamanan (safety factor). Hasil simulasi menunjukkan bahwa benturan samping menghasilkan deformasi dan tegangan maksimum yang lebih tinggi dibandingkan benturan depan, terutama pada material dengan ketebalan pipa yang lebih kecil. Aluminium 6061 memberikan performa terbaik dilihat dari faktor keamanan tertinggi dan tegangan terendah, menandakan potensi penggunaannya sebagai material optimal untuk rangka buggy. Penelitian ini menyimpulkan bahwa pemilihan material dan desain geometri yang tepat sangat krusial dalam meningkatkan kekuatan dan keselamatan rangka tubular untuk aplikasi off-road di medan ekstrem. Temuan ini dapat menjadi acuan dalam pengembangan desain rangka kendaraan off-road yang ringan, kuat, dan aman.

Abstract

Kinerja turbin screw portabel sangat dipengaruhi oleh parameter geometris, namun penelitian sebelumnya lebih banyak berfokus pada variasi jumlah blade dan sudut kemiringan tanpa mengeksplorasi pengaruh jarak pitch secara mendalam, khususnya untuk aplikasi turbin portabel. Penelitian ini mengkaji pengaruh variasi jarak pitch terhadap torsi yang dihasilkan turbin screw portabel menggunakan simulasi Computational Fluid Dynamics (CFD). Tujuan penelitian adalah menentukan konfigurasi jarak pitch optimal untuk memaksimalkan torsi pada sudut kemiringan 45° dengan konfigurasi 1 blade. Model CFD tiga dimensi dianalisis dengan variasi jarak pitch 60 mm, 90 mm, dan 120 mm pada kecepatan aliran air konstan 1 m/s. Hasil simulasi menunjukkan bahwa jarak pitch berpengaruh signifikan terhadap torsi yang dihasilkan, dengan nilai torsi tertinggi sebesar 0,351 Nm pada pitch 60 mm, kemudian menurun menjadi 0,332 Nm pada pitch 90 mm, dan 0,308 Nm pada pitch 120 mm. Disimpulkan bahwa konfigurasi dengan jarak pitch terpendek (60 mm) menghasilkan torsi tertinggi, menjadikannya desain paling efektif untuk aplikasi hidroelektrik portabel pada kondisi aliran rendah. Temuan ini melengkapi kajian optimasi desain turbin screw portabel dan berkontribusi pada pengembangan sistem energi terbarukan skala kecil yang efisien.

Abstract

This study aims to analyze the implementation of the Pancasila Student Profile Strengthening Project (P5) at SMKN 1 Luak District, focusing on applying holistic, contextual, learner-centered, and explorative principles. The research method used is descriptive qualitative with a case study approach. Data were collected through interviews, observations, and documentation and analyzed using the CSE-UCLA evaluation model, which includes the stages of System Assessment, Program Planning, Program Implementation, Program Improvement, and Program Certification. The results showed that implementing P5 in SMKN 1 Luak District still faces various obstacles. The holistic principle has not been optimized due to the lack of integration between learners, teachers, and local communities. The contextual principle has not been fully implemented due to the lack of relevance of the project theme to local needs. In addition, the learner-centered principle is still weak due to the dominance of teachers in the learning process. In contrast, limited facilities and lack of training for teachers hamper the explorative principle. In conclusion, implementing P5 in this school still needs improvement in planning, teacher coordination, learner involvement, and program evaluation. The main recommendations from this study are to improve teacher training, learner involvement in planning, and the selection of themes that are more relevant to local conditions.

Abstract

Vocational education success depends heavily on multiple interconnected factors that influence student academic performance. This study examines the influence of motivation, interest, learning readiness, and study facilities on student learning outcomes in Computer and Basic Networking courses at SMK Negeri 2 Sungai Penuh. Research employed a quantitative approach with a causal correlational design, involving 71 students selected through proportional stratified random sampling. Data was collected using structured questionnaires and analyzed through path analysis. Results revealed that all independent variables significantly influence learning outcomes, with interest having the strongest impact (standardized coefficient=0.392, p<0.001), followed by learning readiness (0.366, p<0.001), motivation (0.212, p<0.001), and study facilities (0.056, p<0.05). Collectively, these variables explain 99.4% of the variance in learning outcomes (R²=0.994). The findings highlight the critical role of student interest in technical subjects and emphasize the importance of a holistic approach that addresses both internal factors (motivation, interest, readiness) and external conditions (facilities). These results suggest that vocational schools should prioritize strategies to enhance student interest through interactive learning methods, ensure adequate learning facilities, and develop comprehensive student readiness programs to optimize educational outcomes.

Abstract

Education plays an important role in improving human resources and shaping adaptive character. To address post-pandemic learning challenges, Indonesia introduced the Merdeka Curriculum, emphasizing flexibility and competency development. This study evaluates the Merdeka Curriculum implementation at SMKN 1 Luak, Lima Puluh Kota Regency, West Sumatra, using the CIPP (Contextual, Input, Process, Product) model. The evaluation covers the 2023/2024 academic year, following its introduction in 2022. A mixed-method approach (qualitative and quantitative) was used for data collection through observations, interviews with teachers, students, and administrators, and analysis of relevant curriculum documents. The results indicate that the context aspect (National Education Standards and School-Level Curriculum) is very good (91.11%). The input aspect (teacher qualifications, infrastructure, reference books) is generally good, but there are shortcomings in qualified teachers, reference books, and subject guidelines. The learning process is rated as adequate (77.18%), with challenges in teaching strategies and student engagement. Student learning outcomes were rated as adequate (79.12%), with room for improvement in critical thinking and problem-solving skills. The Merdeka Curriculum positively impacts education quality, but improvements in facilities, teacher training, and motivation are needed to optimize its effectiveness. These findings suggest schools with similar contexts can benefit by focusing on teaching infrastructure and professional development.
