Analisis Keausan Roll Air Terhadap Hasil Cetak Cover Pada Mesin Offset Heidelberg MOV di CV Aldeaz Sejahtera Printing

Keausan rol air pada mesin Offset Heidelberg MOV dapat memengaruhi kestabilan sistem pembasahan sehingga menurunkan kualitas hasil cetak cover dan menimbulkan cacat cetak, terutama scumming. Tugas Akhir ini bertujuan untuk mengidentifikasi penyebab keausan rol air serta memberikan usulan perbaikan guna mengurangi cacat hasil cetak di CV Aldeaz Sejahtera Printing.
Pengumpulan data dilakukan melalui observasi, wawancara, dokumentasi, dan penggunaan check sheet. Identifikasi penyebab dilakukan menggunakan diagram fishbone berdasarkan faktor man, machine, material, method, dan environment. Hasil identifikasi menunjukkan bahwa penyebab utama keausan rol air meliputi kurangnya pemeriksaan rol secara berkala, tingginya beban kerja rol, kondisi rol yang menurun, penggunaan rol melebihi umur pakai, belum adanya SOP pemeriksaan khusus, serta kebersihan area produksi yang kurang terjaga.
Usulan perbaikan meliputi penyusunan SOP pemeriksaan rol air, pelaksanaan inspeksi berkala menggunakan check sheet, penggantian rol sesuai umur pakai, serta peningkatan kebersihan area produksi. Penerapan usulan tersebut diharapkan dapat mengurangi cacat hasil cetak dan meningkatkan kualitas produksi.

Water roller wear on the Heidelberg MOV Offset printing machine can reduce the stability of the dampening system and affect cover print quality, resulting in defects such as scumming. This final project aims to identify the causes of water roller wear and propose improvements to reduce printing defects at CV Aldeaz Sejahtera Printing.
Data were collected through observation, interviews, documentation, and check sheets. The causes of water roller wear were analyzed using a fishbone diagram based on five factors: man, machine, material, method, and environment. The analysis showed that the main causes include the lack of regular roller inspections, excessive roller workload, deteriorated roller condition, the absence of a specific inspection SOP, the use of rollers beyond their service life, and an insufficiently clean production environment.
The proposed improvements include implementing regular inspections using check sheets, replacing rollers according to their service life, establishing an inspection SOP, and improving workplace cleanliness. These improvements are expected to reduce printing defects and enhance production quality.
