Abstract

Casting defects in cast products will always appear due to the unexpected presence of the X Factor in every casting process. Casting experts can only minimize the appearance of casting defects by carrying out controls starting from the product design process, process design, pattern, mold, melting, and casting to obtain cast products that have quality standards that are free from casting defects. This case study aims to determine the quality control methods carried out by the metal casting industry PT Sinar Mulia Teknalum in overcoming casting defects in ADC 12 Gravity-Die-Casting aluminium alloy cast products, namely adapters, knobs, break drums, and cigarette rolling bases which have shrinkage defects, porosity, mis-run, porous and other types of defects. Quality control for casting defects is carried out in four stages continuously using a solution method that is also a problem solver to Plan, Do, Check, and Action (PDCA) quality control and supporting Seven Tools as a quality control tool. The process of observing casting defects is carried out visually (sight), based on initial data before control is carried out, the product has casting defects of 51.16% shrinkage, 27.91% porosity, 11.63% mis-run, 6.98% porousness, and other defects below 2.33%. Casting defects occur due to the influence of human factors, tools, materials, methods, and environment. After recommendations from the quality control team, corrective steps are taken for each cause of casting defects. Overall casting defects experienced a total interconnected decrease of 29.07%, which included 9.30% shrinkage, 6.98% porosity, 6.98% mis-run, 4.65% porousness, and other defects as much as 1.16%. This reduction in casting defects can be seen as a guide or reference for the work of the PDCA cycle in overcoming casting defects on an ongoing basis in the future.

Abstract

Kampas rem menjadi komponen penting dalam keamanan berkendara. Kampas rem harus memiliki karakteristik ulet, tahan aus, dan keras untuk menciptakan gaya gesek yang optimal. Dipasaran bahan kampas rem banyak dijumpai menggunakan bahan penguat asbestos yang tidak ramah lingkungan dan sangat membahayakan pengguna, oleh karena itu banyak produk kampas rem beralih ke bahan non asbestos yang terbuat dari serat sintetis. Dalam perkembangannya serat sintetis pada kampas rem dapat menimbulkan polutan, sehingga muncul biokomposit. Penelitian ini bertujuan mengetahui karakteristik dan nilai optimum dari biokomposit serat kelapa dan serbuk kulit singkong terhadap ikatan matriks dan kekerasan kampas rem. Metode pembuatan biokomposit menggunakan hand lay up yang dikompaksi beban 20 MPa selama 12 jam dengan variasi komposisi serat kelapa, serbuk kulit singkong, dan matriks polyester sebesar 20:10:70, 30:10:60, 40:10:50, 50:10:40. Untuk mengetahui nilai kekerasan dilakukan uji kekerasan metode Vickers. Hasil uji kekerasan tertinggi pada variasi SK20KS10M70 sebesar 10,08 kgf/mm2 dan terendah pada variasi SK50KS10M40 sebesar 9,88 kgf/mm2. Sedangkan ikatan matriks terbaik pada variasi SK20KS10M70. Kesimpulan hasil pengujian yaitu peningkatan jumlah serat mempengaruhi ikatan matriks dan menurunkan nilai kekerasan kampas rem.
