PENERAPAN PDCA PADA PROSES PRODUKSI DENGAN MENGGUNAKAN MESIN HEIDELBERG SM102 8 COLOUR

Abstract
This research implements the PDCA (Plan-Do-Check-Act) method to improve the quality of Qur'an printing production using the Heidelberg SM 102 8-color machine at PT Gelora Aksara Pratama. The main problems included misregister, doubling, and ink inconsistency, causing up to 141 rejection cases/week. PDCA solutions such as sensor calibration, air pressure adjustment, and routine maintenance successfully reduced rejections by 55% within 4 weeks while improving production time efficiency by 20%. The results prove PDCA's effectiveness in continuous improvement of the printing process.

Penelitian ini menerapkan metode PDCA (Plan-Do-Check-Act) untuk meningkatkan kualitas produksi cetak Al-Qur'an menggunakan mesin Heidelberg SM 102 8 Colour di PT Gelora Aksara Pratama. Masalah utama meliputi misregister, doubling, dan ketidakstabilan tinta yang menyebabkan reject hingga 141 kasus/minggu. Solusi PDCA seperti kalibrasi sensor, penyesuaian tekanan angin, dan perawatan rutin berhasil menurunkan reject sebesar 55% dalam 4 minggu serta meningkatkan efisiensi waktu produksi 20%. Hasil penelitian membuktikan PDCA efektif dalam perbaikan berkelanjutan proses cetak.
