Abstract: | Pengendalian kualitas produk yaitu suatu proses yang dibuat untuk menjaga supaya realisasi sesuai dengan yang direncanakan. PT. Sri Intan Karplas Industry adalah perusahaan yang bergerak di bidang pengolahan bijih plastik sebagai bahan baku utama untuk menjadi karung goni plastik yang digunakan untuk berbagai keperluan industri maupun infrastruktur. Dalam kegiatan produksinya, setiap bulannya terdapat persentase produk cacat sebesar 6,59% - 9,67%. Penelitian ini bertujuan untuk mengetahui faktor penyebab kecacatan produk serta menganalisis hubungan antara cacat yang terjadi dengan kualitas produksi dan memberikan usulan perbaikan dengan menggunakan metode Six Sigma melalui tahap DMAIC (Define, Measure, Analyze, Improve, Control). Hasil penelitian ini menunjukkan bahwa ada beberapa jenis kecacatan pada produk karung goni plastik yang sering terjadi diantaranya adalah jahitan miring dan cetakan miring, yang disebabkan oleh komposisi bahan baku yang tidak sesuai, kelalaian operator, keandalan mesin dan metode kerja yang tidak sesuai. Berdasarkan hasil analisa regresi linier diperoleh hubungan yang kuat antara jumlah cacat dengan kualitas produksi masing-masing sebesar 39%, artinya cacat jahitan miring dan cacat cetakan miring memberikan kontribusi sebesar 39% terhadap kegagalan produk, sedangkan sisanya dipengaruhi oleh variabel lain yang tidak disebutkan dalam penelitian ini. |
Description: | The product quality control is a process of maintaining all the efforts are realized as planned as to the company. PT Sri Intan Karplas Industry is a company runs in the field of processing plastic ore as the main material in producing the plastic jute sack for industrial purposes, even infrastructure. The defective products percentage as much as 6.59% - 9.67% occurs in the production activities every month. The research aims to discover factors that causing the defective products along with analyzing the relationship between the defective towards quality product and provide suggestions to improve by utilizing Six Sigma method. The method is used to DMAIC phase (Define, Measure, Analyze, Improve, and Control). The result reveals that the defectives on plastic jute sack usually occur on the sloped of seams and mold. This is due to several cases such as unmatched of materials composition, operator negligence, machine’s reliability, and inappropriate working method. Based on the linear regression analysis, a robust relationship has been found between total defective of product and quality product as much as 39% respectively. This indicates that sloped of seams and mold give the contribution about 39% towards product failure. Meanwhile, for the rest elements might be contributed by other variables which are not included in the study. |
