Pengontrolan Alur Kerja Pada Mesin Cetak Spanduk Terhadap Kualitas Produksi Cetak di SGF Advertising dan Printing

ABSTRACT

This final project examines workflow control in banner printing machines as a strategic effort to improve production quality at SGF Advertising and Printing. This study applies the Six Sigma method using the DMAIC approach (Define, Measure, Analyze, Improve, Control) to identify the root causes of production defects and to design systematic and sustainable improvement solutions. Data were collected through direct observation, interviews, and statistical documentation of production outputs and defect rates during the period from January to May 2025. The focus of the observation covers all workflow stages of the Allwin E320s machine, including pre-press, printing, and finishing. The analysis revealed that variations in print quality were mainly caused by human error (lack of attention), machine conditions (printhead, sensors), printing materials (dust, texture), and the work environment (cleanliness, temperature). Improvements were implemented through enhanced standard operating procedures (SOPs), scheduled maintenance, and consistent design proofing, which significantly reduced the defect rate and improved print accuracy and sharpness. This study contributes to the practical implementation of data-driven quality control systems in the printing industry and serves as a useful reference for both students and graphic industry practitioners in understanding the importance of workflow control and the Six Sigma methodology in achieving superior production quality.

ABSTRAK

Tugas akhir ini membahas pengontrolan alur kerja pada mesin cetak spanduk di SGF Advertising dan Printing sebagai strategi untuk meningkatkan kualitas produksi. Penelitian ini menggunakan metode Six Sigma dengan pendekatan DMAIC (Define, Measure, Analyze, Improve, Control) untuk mengidentifikasi sumber cacat dan merancang solusi perbaikan secara sistematis. Data dikumpulkan melalui observasi, wawancara, dan pencatatan statistik produksi selama Januari hingga Mei 2025. Fokus pengamatan mencakup seluruh tahapan kerja mesin Allwin E320s, dari pra-cetak hingga finishing. Hasil analisis menunjukkan bahwa cacat produksi dipengaruhi oleh faktor manusia (kurang teliti), kondisi mesin (printhead, sensor), bahan cetak (debu, tekstur), serta lingkungan kerja (kebersihan, suhu). Perbaikan dilakukan melalui penguatan SOP, perawatan rutin, dan proofing desain secara konsisten, yang terbukti menurunkan tingkat cacat dan meningkatkan kualitas cetak. Penelitian ini diharapkan tidak hanya memberikan kontribusi dalam penerapan sistem pengendalian mutu berbasis data di industri percetakan, tetapi juga menjadi referensi praktis bagi mahasiswa maupun pelaku usaha grafika dalam memahami pentingnya workflow control dan metode Six Sigma dalam menciptakan kualitas produksi yang unggul.
