Abstract

The racing cast wheel made of aluminum 6061-T6 is a critical component in motor vehicles, particularly in supporting performance, safety, and aesthetics. This study aims to analyze the mechanical performance of the wheel through Finite Element Analysis (FEA) simulation. The FEA simulation was conducted using Ansys 18.1 software with a load of 1500 N, covering both static and dynamic loading conditions. The material tested is Aluminum Alloy 6061-T6, with material properties derived from tensile testing. The simulation results indicate that maximum stress occurs in critical areas, such as bolt holes and the intersection of spokes with the wheel rim, with a maximum stress value of 46.027 MPa. This stress level remains below the material's yield strength (276 MPa), demonstrating that the design is safe from plastic deformation. The total deformation observed is 0.053 mm, which is negligible and does not affect the wheel's functionality. A safety factor exceeding 2.5 confirms that the wheel can withstand more extreme loads. Based on these findings, design optimizations such as adding fillets and surface treatments are recommended to enhance the wheel's reliability. This research provides valuable insights for the development of stronger, lighter, and more durable wheels, particularly suited to the diverse road conditions found in Indonesia.

Abstract

This study aims to determine the effect of self-efficacy on learning outcomes of vocational high school students in the context of implementing a competency-based curriculum. The approach used is quantitative with an ex post facto method. The study population was grade XI students of SMK Nasional Malang, with a total sample of 92 students taken (saturated sampling). Self-efficacy data were obtained through a questionnaire using a Likert scale, while learning outcome data were obtained from mid-semester report card scores. The results of the linear regression test showed that the data were normally distributed and had a linear relationship. The t-test showed that self-efficacy had a significant effect on student learning outcomes (p < 0.05). These findings confirm that self-efficacy is an important indicator in supporting the achievement of learning outcomes, especially in vocational education that demands students' independence, responsibility, and readiness to face the challenges of practice-based learning. Students with high self-efficacy tend to have better learning motivation, are able to manage learning strategies effectively, and demonstrate a high level of independence in completing assignments. Therefore, learning development in vocational high schools should not only emphasize technical aspects, but also need to strengthen students' self-confidence in achieving learning success.

Abstract

Penelitian ini bertujuan menganalisis pengaruh media pendingin air mineral dan air cucian detergen terhadap kekuatan tarik baja ST 37 hasil pengelasan SMAW. Metode yang digunakan adalah eksperimen dengan variabel bebas berupa jenis media pendingin, sedangkan variabel terikatnya adalah kekuatan tarik. Proses pengelasan dilakukan menggunakan elektroda LB-52U pada arus 90 A, kemudian spesimen didinginkan dengan air mineral atau air cucian detergen pada suhu ruang. Uji tarik menggunakan Universal Testing Machine menghasilkan tegangan tarik maksimum sebesar 234,2 MPa untuk pendinginan air mineral dan 110,0 MPa untuk pendinginan air cucian detergen. Perbedaan ini menunjukkan bahwa pendinginan cepat dengan air mineral lebih efektif meningkatkan kekuatan tarik, sedangkan kandungan kimia pada air cucian detergen berpotensi menurunkan performa mekanik melalui laju pendinginan yang lebih lambat dan potensi korosi awal. Hasil penelitian ini memberikan kontribusi dalam pemilihan media quenching yang tepat serta pemanfaatan limbah cair secara bijak.

Abstract

Velg yang kuat dapat berkontribusi signifikan dalam mengurangi bobot sepeda motor, yang pada akhirnya dapat meningkatkan efisiensi bahan bakar dan memberikan pengalaman berkendara yang lebih ramah lingkungan. Secara keseluruhan, desain velg CB150R berbahan alloy steel sangatlah menarik dan sporty. Namun memiliki kekurangan yaitu harganya lebih mahal daripada velg berbahan baja dan sulit untuk diperbaiki jika mengalami kerusakan. Solidworks yang memungkinkan pengguna menentukan dimensi dan hubungan antara berbagai elemen sketsa. Setelah sketsa dasar dibuat, langkah selanjutnya adalah mengubahnya menjadi model 3D. Hal ini memungkinkan para insinyur dan desainer untuk mengidentifikasi potensi masalah dan kelemahan dalam suatu desain sebelum membuat prototipe fisik. Hasil perhitungan static displacement memberikan informasi tentang perubahan bentuk, perpindahan, atau deformasi struktur yang terjadi akibat beban statis. Informasi ini penting dalam perancangan struktur yang mempertimbangkan kinerja struktural, kekuatan material, dan keamanan. Static displacement dapat diukur atau dihitung diberi 2 N/m2 sebagai perubahan posisi suatu titik atau elemen dalam struktur akibat beban yang dikenakan. Diketahui factor of safety terbesar yaitu 3,1e+06 dan terkecil 2,150e+09 bisa juga untuk mengetahui pembeban 2 N/m² yang diberikan.  Berdasarkan nilai dari factor of safety pada tekanan 2 N/m² mendapatkan nilai 2,3 yang berarti struktur atau material tersebut memiliki daya tahan yang diperlukan untuk menahan beban yang diantisipasi.
