<![CDATA[Proses produksi telah banyak berevolusi dengan diperkenalkannya konsep manufaktur inovatif yang handal. Salah satu komponen mesin yang banyak diproduksi adalah cylinder head. Cylinder head harus tahan terhadap temperatur dan tekanan yang tinggi selama engine bekerja. Oleh sebab itu umumnya cylinder head dibuat dari besi tuang. Kendala yang ada saat ini yaitu proses pembuatan cylinder head kurang efektif dan efisien karena ketika menetapkan sudut untuk membuat reamer berbasis manual, selain itu setting benda kerja tidak otomatis sehingga membutuhkan waktu yang terlalu lama. Solusi dari permasalahan tersebut yaitu dengan adanya jig dan fixture. Metode penelitian yang digunakan adalah metodologi perancangan fixture (Society of Manufacturing Engineers). Berdasarkan hasil analisis, terdapat kelebihan dari jig dan fixture yang telah dirancang ulang yaitu: 1) memiliki stoper yang berfungsi untuk memberhentikan benda kerja, dengan sudut yang sudah ditentukan sehingga tidak perlu mensetting sudut kembali; 2) tidak mudah bergeser apabila fixture dipasang dan sejajar di meja frais; 3) terdapat dua engsel sehingga lebih balance; 4) pemasangan tidak rumit sehingga tidak memakan banyak waktu dalam pembuatan produk.Kata kunci: Jig and fixture; redesign; head cylinder The production process has evolved a lot with the introduction of innovative reliable manufacturing concepts. One of the engine components that are widely produced is the cylinder head. The cylinder head must withstand high temperatures and pressures while the engine is running. Therefore, generally the cylinder head is made of cast iron. The current constraint is that the cylinder head manufacturing process is less effective and efficient because when setting the angle to make the reamer a manual basis, besides that the workpiece setting is not automatic so it takes too long. The solution to this problem is the presence of jigs and fixtures. The research method used is the fixture design methodology (Society of Manufacturing Engineers). Based on the results of the analysis, there are advantages to the redesigned jig and fixture, namely: 1) it has a stoper which functions to stop the workpiece, at a predetermined angle so that there is no need to set the angle again; 2) it does not move easily when the fixture is installed and parallel to the milling table; 3) there are two hinges so that it is more balanced; 4) installation is not complicated so it does not take much time to manufacture the product.Keywords : Jig and fixture; redesign; head cylinder.
