Abstract

Proses perancangan produk menjadi hal yang sangat penting dalam menentukan efisiensi biaya dan waktu produksi. Terutama jika produk tersebut terdiri dari banyak komponen penyusun seperti Rotor Head Gyroplane milik PT. Bayu Aircraft Indonesia.Penelitian ini bertujuan untuk membuktikan bahwa desain sangat berpengaruh pada keseluruhan aspek produk, salah satunya pada tingkat kesulitan perakitan suatu produk.Analisa yang dilakukan dalam penelitian ini menggunakan analisa Design for Assembly (DFA) pada software Design Manufacturing and Assembly (DFMA) Boothroyd dan Dewhurst.Langkah awal yang dilakukan adalah mengidentifikasi komponen penyusun dan tahapan perakitan rotor head. Kemudian menganalisa desain awal yang telah digunakan oleh perusahaan untuk mendapatkan data terkait minimum part criteria, labor time, labor cost, assembly tool/fixture, item costs, total cost dan DFA indeks. Selanjutnya menganalisa desain perbaikan rotor head dari hasil Focus Group Discussion.Kemudian membandingkan secara keseluruhan untuk mendapatkan desain terbaik berdasarkan konsep DFA.Hasil analisa menunjukkan bahwa desain perbaikan memiliki efisiensi perakitan lebih tinggi dibandingkan dengan desain awal. Hal itu ditunjukkan pada peningkatan DFA Indeks, di mana pada desain awal adalah 1,58 dan pada desain perbaikan menjadi 2,14. Untuk waktu pengerjaan dan biaya tenaga kerja dapat direduksi masing-masing sebanyak 23,34% dan 23,68%. Sistem perakitan ini juga menjadi lebih meningkat dengan dilakukannya perbaikan layout kerja dan penambahan fixture.Di mana dapat meningkatkan DFA Indeks menjadi 2,24 dan mereduksi waktu pengerjaan serta biaya tenaga kerja masing-masing sebanyak 49,84% dan 34,21%. Hal tersebut membuktikan bahwa perancangan desain suatu produk memiliki pengaruh penting terhadap tingkat kesulitan perakitan dan produksinya ================================================================================================ The design process the product being of crucial importance in determining of cost efficiency and production time . Especially if that product consisting of many components building blocks as the RotorHeadGyroplane owned by PT . Bayu Aircraft Indonesia. The cost and labor time of the assembly process as well as the labor costs incurred to assemble the product of obstruction depend on the level of difficulty and the number of components that must be assembled. This study aims to prove that the design is very influential on the overall aspects of the product, one of them on the level of difficulty of assembling a product. The analysis performed in this study is done using analysis Design for Assembly (DFA) on software Design Manufacturing and Assembly (DFMA) Boothroyd and Dewhurst. The first step is to identify the constituent components and rotor head assembly stages as well as references to other related. Then analyze the initial design has been used by companies to obtain data related to minimum criteria parts, labor time, labor cost, assembly tool / fixture, item costs, total costs and DFA index. Next is to analyze the design of improvement rotor head from the Focus Group Discussion based on aspects of the analysis in the early design. Then compare overall to get the best design based on the concept of DFA. The analysis result showed that the initial design can be improved to increase the efficiency of the assembly. It was shown in the increase in DFA index, in which the initial design was 1,58 and the design of improvements to be 2,14. For working time and labor costs can be reduced as much as respectively 23.68% 23.34% and. The assembly system also be further improved by the work done layout improvements and additions to the fixture. Where can increase the DFA index becomes 2,24 and reducing processing time and labor costs each as much as 49.84% and 34.21%. It is proved that designing a product has a significant influence on the level of difficulty of assembly and production
