Pengukuran Nilai Sigma Kualitas Material Produksi Kompor Pada Perusahaan Di Pabrik Kompor Bogor

Abstract

Perusahaan industri sedang mengalami perkembangan yang sangat pesat, terutama dalam bidang manufaktur. karena perkembangan yang sangat pesat, setiap perusahaan memiliki pesaing yang memproduksi produk yang sama dengan produk yang dihasilkan. Untuk menarik perhatian konsumen, berbagai cara dilakukan oleh perusahaan, seperti meningkatkan kualitas produk, sehingga konsumen merasa tertarik. Namun, meski proses produksi telah dilaksanakan dengan baik sesuai prosedur, pada kenyataannya sering ditemukan ketidaksesuaian antara produk yang dihasilkan dengan yang diharapkan, dimana kualitas produk yang dihasilkan tidak sesuai dengan standar. Metode yang diambil sesuai masalah diatas yaitu dengan metode six sigma dan diagram pareto. Six sigma merupakan salah satu alat pengendalian kualitas yang berfokus pada minimasi variasi proses untuk mengurangi kecacatan produksi dengan teknik analisis statistik sehingga lebih efisien dan mampu meningkatkan kepuasan konsumen dan untuk diagram pareto untuk memperlihatkan grafik batang yang menunjukkan masalah berdasarkan urutan banyaknya jumlah kejadian. Berdasarkan penelitiaan dan analisa data yang telah dilakukan pada bab sebelumnya, maka dapat diperoleh kesimpulan pada penelitian ini antara lain, berdasarkan data diatas terdapat 24 material yang persentasenya 80% sesuai dengan prinsip diagram pareto. Dan material yang paling banyak memiliki defect terbesar adalah water plate GLI (big burner). Setelah dilakukan analisa terdapat total defect sebesar 398, total unit sebesar 33.500, total opportunities sebesar 42 peluang, total opportunities sebesar 57.200, defect per oppertunities totaly 0.006958, dan hasil nilai Defect per Million Opportunities dengan hasil 6958.041958, setelah dikonversi ke nilai sigma didapatkan hasil 2,70 yang berada pada sigma level 2 (rata – rata industri Indonesia).

Industrial companies are experiencing very rapid development, especially in the manufacturing sector. Due to very rapid development, every company has competitors who produce the same products as the products they produce. To attract consumers' attention, companies use various methods, such as improving product quality, so that consumers feel interested. However, even though the production process has been carried out well according to procedures, in reality discrepancies are often found between the products produced and those expected, where the quality of the products produced does not comply with standards. The method taken is appropriate to the problem above, namely the six sigma method and the Pareto diagram. Six sigma is a quality control tool that focuses on minimizing process variations to reduce production defects with statistical analysis techniques so that it is more efficient and able to increase customer satisfaction and for Pareto diagrams to show bar graphs that show problems based on the order of the number of events. Based on the research and data analysis that has been carried out in the previous chapter, conclusions can be drawn from this research, including, based on the data above, there are 24 materials whose percentage is 80% in accordance with the Pareto diagram principle. And the material that has the largest defects is the GLI (big burner) water plate. After the analysis, there were total defects of 398, total units of 33,500, total opportunities of 42 opportunities, total opportunities of 57,200, total defects per opportunity of 0.006958, and the resulting value of Defects per Million Opportunities was 6958.041958, after converting to sigma value the result was 2 .70 which means it is at sigma level 2 (Indonesian industry average).the resulting Defect per Million Opportunities value was 6958.041958, after converting to a sigma value the result was 2.70, which means it is at sigma level 2 (Indonesian industry average). In other words, the Six Sigma value is 2.70, which shows that the process still has several opportunities for improvement because the variability is still quite high. The higher the Sigma value, the better the process capability.
