Abstract

Perubahan pola hidup dan kebutuhan konsumen mendorong industri manufaktur senantiasa melakukan perbaikan desain dan pengembangan produk agar tetap berdaya saing dalam kompetisi pasar. Product redesign menjadi salah satu upaya pengembangan produk sekaligus penurunan biaya manufaktur. Design for Manufacturing and Assembly (DFMA) merupakan salah satu pendekatan dalam perancangan produk dengan mengevaluasi aspek manufaktur dan perakitan untuk mereduksi biaya. Identifikasi komponen kritis menjadi tahap mendasar dalam product redesign dengan mempertimbangkan kebutuhan pelanggan dari data keluhan dan kegagalan historis untuk meningkatkan keandalan produk. Penelitian ini mengembangkan model DFMA dan Design for Reliability dalam suatu kerangka konseptual terintegrasi untuk product redesign, dengan mempertimbangkan kebutuhan konsumen, komplain pengguna, dan prediksi keandalan. Pengembangan model pertama berbasis pendekatan Kano-FMEA QFD yang dikembangkan untuk identifikasi prioritas redesain komponen produk dengan mempertimbangkan kebutuhan konsumen, komplain pengguna, dan mode kegagalan produk. Kedua, model integrasi Design for Manufacturing, Assembly, and Reliability (DFMAR) dikembangkan dengan mengintegrasikan model DFMA dan model design for reliability untuk produk redesain untuk penurunan biaya dan prediksi keandalan. Ketiga, pengambilan keputusan dalam pemilihan produk redesain terbaik dari implementasi model DFMAR dilakukan dengan pendekatan Analytical Hierarchy Process (AHP). Penelitian ini menghasilkan 3 (tiga) kesimpulan penting. Pertama, penggunaan kebutuhan konsumen dan komplain pengguna yang dikolaborasikan dengan mode kegagalan produk terbukti mampu memprioritaskan resiko komponen yang akan diredesain dengan penggunaan pendekatan Kano-FMEA QFD. Kedua, model integrasi DFMAR terbukti mampu membantu menurunkan biaya manufaktur, memperbaiki efisiensi dan keandalan produk redesain. Ketiga, penggunaan kriteria biaya, kemudahan manufaktur & perakitan, serta keandalan terbukti dapat membantu pengambil keputusan memilih alternatif produk redesain terbaik

Changes in lifestyle and consumer needs encourage the manufacturing industry to constantly improve product design and development to remain competitive in the market competition. Product redesign is one of the efforts to develop products while reducing manufacturing costs. Design for Manufacturing and Assembly (DFMA) is one approach in product design by evaluating manufacturing and assembly aspects to reduce costs. Identifying critical components is a fundamental stage in product redesign by considering customer needs from complaint data and historical failures to improve product reliability. This research develops DFMA and Design for Reliability models in an
consumer needs, user complaints, and reliability predictions. The first model development is based on the Kano-FMEA QFD approach developed to identify product component redesign priorities by considering consumer needs, user complaints, and product failure modes. Second, a Design for Manufacturing, Assembly, and Reliability (DFMAR) integration model was developed by integrating the DFMA model and the design for reliability model for product redesign for cost reduction and reliability prediction. Third, decision-making in selecting the best-redesigned product from implementing the DFMAR model was carried out using the Analytical Hierarchy Process
(AHP) approach. This research resulted in 3 (three) essential conclusions. First, the use of consumer needs and user complaints collaborated with product failure modes proved to be able to prioritize the risk of components to be redesigned using the Kano-FMEA QFD approach. Secondly, the DFMAR integration model is proven to help reduce manufacturing costs and improve the efficiency and reliability of redesigned products. Third, the use of cost, ease of manufacturing & assembly, and reliability criteria are proven to help decision-makers choose the best redesign product alternative
