Abstract
ABSTRACT Within the company, it is necessary to implement an appropriate quality control system to improve product quality, reduce the number of product defects and increase customer satisfaction. PT Koyorad Jaya Indonesia is a company engaged in manufacturing that produces automotive Radiator. Several defects were found which became the problem of product quality not meeting standards. The purpose of this study is to determine whether the number of defects is still within the control limits or not, analyze the factors causing product defects and provide repair solutions to reduce the number of defects that occur in the production section. The method used in this study is the Statistical Quality Control (SQC) method of data processing including calculating the p control chart (Control Chart), Pareto chart (Pareto Chart) and cause and effect diagram (cause and effect diagram). The results showed that there were three types of product defects, namely Bad colour for visual, non- leak tube products and Striped wire. By calculation using the control chart p shows that there are no product defects that are out of control limits, then the analysis uses a Pareto diagram the dominant type of defect is Bad colour for visual, the second order is the product is leak tube and the last is striped wire, the analysis uses a cause-and-effect diagram. shows that the causes of product defects include human factors, machines, materials, methods and parameter. To reduce the number of defects that occur at PT Koyorad Jaya Indonesia, it can be done by providing education or training to employees, especially machine and production operators. ABSTRAK Di dalam perusahaan diperlukan penerapan sistem pengendalian kualitas yang tepat untuk memperbaiki kualitas produk, mengurangi jumlah cacat produk (defect) serta dapat meningkatkan kepuasan pelanggan. PT Koyorad Jaya Indonesia adalah perusahaan yang bergerak di bidang manufaktur yang memproduksi radiator mobil ditemukan beberapa defect yang menjadi permasalahan kualitas produk tidak sesuai standar. Tujuan pada penelitian ini adalah untuk mengetahui apakah jumlah defect masih dalam batas kendali atau tidak, menganalisis faktor penyebab cacat produk serta memberikan solusi perbaikan untuk menekan jumlah defect yang tejadi pada bagian produksi. Metode yang digunakan pada penelitian ini adalah metode Statistical Quality Control (SQC) pengolahan data diantaranya menghitung peta kendali p (Control Chart), diagram Pareto (Pareto Chart) dan diagram sebab-akibat (cause and effect diagram). Hasil penelitian menunjukkan bahwa terdapat tiga jenis cacat produk yaitu warna buluk, produk bocor tube dan produk belang kawat. Dengan perhitungan menggunakan peta kendali p menunjukan bahwa tidak ada defect produk yang keluar dari batas kendali, kemudian analisis menggunakan diagram Pareto jenis defect yang dominan yaitu warna buluk, urutan ke dua yaitu produk belang kawat dan yang terakhir produk bocor tube, analisis menggunakan diagram sebab-akibat menunjukkan bahwa penyebab defect produk antara lain faktor manusia, mesin, material, metode dan parameter. Untuk menekan jumlah defect yang terjadi di PT Koyorad Jaya Indonesia dapat dilakukan dengan cara memberikan edukasi atau pelatihan kepada karyawan terutama operator mesin dan produksi.
