Abstract

This descriptive study aims to analyze the effect of shaft diameter on the natural frequency and maximum deformation of a rotating shaft system. The analysis was conducted through numerical simulation using ANSYS Workbench software. The shaft and two symmetrically positioned disks were modeled, and a modal analysis was performed using the Finite Element Method (FEM) to determine the system’s first ten vibration modes. Simulation results showed that the natural frequencies ranged from 80.495 Hz to 280.4 Hz, with a maximum deformation of 58.903 mm occurring in the 9th mode. The lower modes (modes 1–6) exhibited lower frequencies but higher deformation, while higher modes (modes 7–10) showed more complex vibration patterns with consistently significant deformation values. This indicates that higher frequency does not necessarily result in lower deformation, and the system may still experience critical vibration. These findings demonstrate that the shaft's geometric configuration, including diameter and mass distribution of the disks, significantly affects its dynamic behavior. The simulation provides deeper insight into the vibration characteristics of the critical speed shaft apparatus used in practical experiments and serves as a reference for validating theoretical approaches such as the Dunkerley and Rayleigh methods.

Abstract

Drum brakes are one of the crucial components in motor vehicle braking systems, particularly in motorcycles, due to their advantages in production cost and resistance to environmental contamination. However, this type of brake has limitations in dissipating heat during braking, which can lead to temperature accumulation, thermal deformation, and reduced braking efficiency. This study aims to analyze the thermo-mechanical performance of drum brakes with various cooling groove designs (solid, straight-grooved, and slant-grooved) using a numerical method based on Finite Element Analysis (FEA) in ANSYS Workbench. The analysis was conducted in a transient manner, both thermally and structurally, to evaluate temperature distribution and total deformation for each design. The results show that the slant-grooved drum brake design yields the lowest temperature distribution and total deformation values, especially at high braking speeds, with a temperature distribution of 56.899?°C and total deformation of 17.67?×?10?³?mm. These findings indicate that groove design significantly affects the heat dissipation and structural deformation performance of the brake system. The study concludes that the slant-grooved design is superior in reducing heat and deformation, thereby offering the potential to improve braking safety and efficiency.

Abstract

Kesenjangan antara capaian pembelajaran pendidikan vokasi Rekayasa Perangkat Lunak dan kebutuhan industri masih terlihat, terutama dalam kemampuan pemecahan masalah kompleks, kolaborasi tim, dan pembelajaran berkelanjutan. Penelitian ini bertujuan menganalisis bagaimana manajemen kurikulum berbasis deep learning dan growth mindset diimplementasikan untuk meningkatkan kompetensi peserta didik. Penelitian menggunakan desain studi kasus kualitatif pada satu institusi pendidikan vokasi. Data dikumpulkan melalui wawancara dengan pemangku kepentingan sekolah, observasi proses pembelajaran, dan analisis dokumen kurikulum, kemudian dianalisis menggunakan teknik analisis tematik melalui tahap reduksi data, kategorisasi, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa manajemen kurikulum dilaksanakan secara sistematis melalui perencanaan, pengorganisasian, pelaksanaan, dan evaluasi yang selaras dengan kebutuhan industri digital. Pendekatan deep learning diterapkan melalui pembelajaran berbasis proyek, studi kasus autentik, dan portofolio digital yang mendorong pemahaman konseptual serta berpikir kritis, sementara growth mindset dikembangkan melalui refleksi pembelajaran, umpan balik konstruktif, dan budaya sekolah yang menekankan proses dan ketekunan. Integrasi kedua pendekatan tersebut memperkuat pengembangan kompetensi teknis dan nonteknis peserta didik. Temuan ini menegaskan pentingnya manajemen kurikulum yang adaptif dan berbasis kebutuhan industri, serta merekomendasikan penguatan kolaborasi dengan dunia industri dan integrasi sertifikasi kompetensi berbasis proyek untuk meningkatkan kesiapan lulusan
