Abstract

Sistem exhaust pada alat berat bekerja pada temperatur tinggi dan lingkungan operasi yang ekstrem sehingga membutuhkan material muffler yang mampu mempertahankan kekuatan struktur, memiliki ketahanan termal yang baik, serta menjamin keandalan selama masa operasi. Pemilihan material yang kurang tepat dapat menyebabkan peningkatan tegangan, deformasi, dan penurunan umur pakai komponen. Oleh karena itu, diperlukan analisis karakteristik termal dan respons struktur untuk menentukan material muffler yang paling sesuai. Laporan magang ini bertujuan mendeskripsikan kegiatan mahasiswa selama melaksanakan magang di PT Aletek Global Indonesia sekaligus menganalisis performa tiga material muffler, yaitu Mild Steel, Stainless Steel 409, dan Aluminized Steel Type 1, sebagai dasar rekomendasi pemilihan material. Metode yang digunakan meliputi kegiatan perancangan komponen menggunakan SolidWorks, penyusunan gambar teknik, serta simulasi berbasis Computer-Aided Engineering (CAE). Analisis diawali dengan simulasi termal pada model muffler untuk memperoleh distribusi temperatur, kemudian dilanjutkan dengan analisis struktur menggunakan parameter von Mises stress, total deformation, dan safety factor sebagai indikator kinerja masing-masing material. Hasil simulasi menunjukkan bahwa Aluminized Steel Type 1 memberikan performa terbaik dibandingkan Mild Steel dan Stainless Steel 409. Material tersebut menghasilkan nilai safety factor minimum tertinggi sebesar 0,6407, tegangan von Mises maksimum terendah sebesar 404,56 MPa, serta deformasi maksimum sebesar 11,184 mm. Hasil tersebut menunjukkan bahwa Aluminized Steel Type 1 memiliki keseimbangan yang lebih baik antara ketahanan termal dan kekuatan struktur sehingga lebih direkomendasikan untuk aplikasi muffler pada alat berat. Selain meningkatkan kompetensi teknis mahasiswa di bidang desain dan simulasi rekayasa, kegiatan magang ini juga memberikan kontribusi terhadap proses evaluasi material dan pengembangan desain produk di PT Aletek Global Indonesia.

Heavy-duty exhaust systems operate under high-temperature and extreme environmental conditions, requiring muffler materials with excellent thermal resistance, structural strength, and long-term reliability. Inappropriate material selection may lead to increased stress, excessive deformation, and reduced service life of the component. Therefore, an evaluation of the thermal characteristics and structural response of muffler materials is essential to determine the most suitable material for heavy-duty applications. This industrial internship report aims to describe the author's activities during the internship at PT Aletek Global Indonesia while analyzing the performance of three muffler materials, namely Mild Steel, Stainless Steel 409, and Aluminized Steel Type 1, as a basis for material selection. The methodology involved engineering design activities using SolidWorks, preparation of engineering drawings, and Computer-Aided Engineering (CAE) simulations. The analysis began with thermal simulation to determine the temperature distribution within the muffler model, followed by structural analysis using von Mises stress, total deformation, and safety factor as the primary performance indicators for each material. The simulation results indicate that Aluminized Steel Type 1 exhibited the best overall performance compared with Mild Steel and Stainless Steel 409. This material achieved the highest minimum safety factor of 0.6407, the lowest maximum von Mises stress of 404.56 MPa, and a maximum deformation of 11.184 mm. These findings demonstrate that Aluminized Steel Type 1 provides a better balance between thermal resistance and structural integrity, making it the most suitable material for heavy-duty muffler applications. Furthermore, the internship enhanced the author's technical competencies in engineering design and simulation while contributing to the material evaluation and product development process at PT Aletek Global Indonesia.
