Abstract

Persaingan di industri otomotif menuntut peningkatan kualitas produk untuk memenuhi kebutuhan pelanggan.Penelitian ini menganalisis kualitas radiator cover merek ARM dengan pendekatan Quality Function Deployment(QFD) dan House of Quality (HoQ). Data diperoleh melalui survei terhadap 30 konsumen yang telah menggunakanproduk selama lebih dari enam bulan, serta wawancara dengan produsen dari divisi research and development (R&D)dan produksi. Matriks HoQ digunakan untuk menerjemahkan kebutuhan pelanggan menjadi spesifikasi teknis produk.Hasil penelitian menunjukkan bahwa desain produk (19%), material berkualitas (16%), variasi warna (16%), dankeseimbangan harga-kualitas (16%) merupakan prioritas utama dalam pengembangan produk. Dibandingkan dengankompetitor, produk ARM menunjukkan keunggulan dalam aspek desain dan kualitas material. Penelitian inimemberikan rekomendasi strategis bagi produsen untuk mengembangkan produk secara berkelanjutan yang lebihsesuai dengan kebutuhan pasar, serta memperkuat posisi kompetitifnya di industri otomotif nasional

Abstract

This study investigates the effects of different types of carbonyl iron particles on the structure and performance of magnetorheological elastomers (MREs). Employing various experimental methodologies, including frequency and strain-dependent testing, the mechanical performance of both anisotropic and isotropic MREs was analyzed. Results indicate that the spatial location of particle chains, frequency, dynamic strain amplitude, and prestrain substantially influence the MREs' mechanical behavior. Special focus was given to the integration of nanoparticles, which significantly enhanced performance metrics. Comparisons were made between MREs based on epoxy, silicone rubber, and polyurethane/Si-rubber hybrids, emphasizing their rheological and morphological properties post-natural weathering in a tropical climate. Additionally, the study highlights the potential applications of MREs in automotive components and sensor technologies, with particular attention to the magnetic and mechanical properties mediated by the inclusion of carbon black and cobalt. The findings provide a comprehensive understanding of the adaptive magnetoelastic characteristics of MREs, contributing to their development and deployment in various smart material applications.
