Abstract
Proses perakitan dan manufaktur memiliki peranan penting pada pengembangan produk sepeda pascastroke yang telah dinuat oleh Jurusan Teknik Mesin-FTI Institut Teknologi Sepuluh Nopember Surabaya. Proses sepeda ini diharapkan dapat membantu proses rehabilitasi pasien pascastroke dan dapat bersaing di pasar dengan produk-produk penunjang rehabilitasi sejenisnya. Pengembangan produk yang dilakukan dengan konsep Design for Manufacturing and Assembly (DFMA). Konsep DFMA terkait dengan jumlah komponen, waktu perakitan, berat produk dan biaya manufaktur. Penelitian ini diharapkan dapat menghasilkan peningkatan assembly efficiency, pengurangan jumlah komponen, dan pengurangan berat produk sepeda.
Penelitian ini dimulai dengan studi terhadap desain awal komponen sepeda pascastroke. Selanjutnya dianalisa menggunakan software DFMA. Dari hasil analisa tersebut dikembangkan beberapa desain baru dengan menghilangkan atau menggabungkan komponen yang tidak memberi nilai tambah. Sehingga diperoleh reduksi waktu perakitan, jumlah komponen, biaya komponen produk sepeda. Komponen yang mengalami redesign adalah rangka depan, rangka tengah dan rangka depan.
Hasil analisa desain baru yang terbaik menunjukkan terjadi perubahan jumlah komponen dari 148 menjadi 71, reduksi waktu total perakitan dari 1072,76 detik menjadi 461,2 detik, berat produk dari 23,42 kg menjadi 8,87 kg dan assembly efficiency indeks dari 5,9 menjadi 11,7.
=====================================================================
Assembling and manufacturing process has an important role in product development of post-stroke bicycle while are produced by mechanical engineering department -FTI Institut Teknologi Sepuluh Nopember Surabaya. This expected to help the rehabilitation process of product is after stroke patients and can be competitive in the market. Product development in this research use Design for Manufacturing and Assembly (DFMA) concept. This concept associated with the component count, assembly time, product weight and manufacturing costs. This research is expected to result in increased assembly efficiency, reduction in the number of component and reduction in product weight.
The research began with a study of the initial design of post-stroke bike components. Then further analyzed using DFMA software. From this analysis developed several new designs by eliminating or combining components that do not add value. Thus obtained the reduction of assembly time, the number of components, the component costs of bicycle products. The components that undergo redesign is the next frame, the middle frame and the front frame.
The results of the analysis of a new design that best shows the changes in the number of components from 148 to 71, the total assembly time reduction of 1072.76 seconds to 461.2 seconds, the product weight of 23.42 kg to 8.87 kg and assembly efficiency index of 5, 9 to 11.7.
