<![CDATA[The Tuber T-645M machine is utilized in the production of cement bags made from kraft paper (pasted bags), converting paper rolls into semi-finished tubular forms (tubes). The Tuber machine consists of several operational sections, one of which is the Cutting Unit area. The Cutting Unit is responsible for cutting the continuously formed tubes produced by the Tube Forming Unit into predetermined lengths. Currently, the Cutting Unit does not have a scheduled component replacement program; therefore, components are replaced only after failure occurs. This condition leads to excessive machine downtime and disrupts the production process. This study aims to identify critical components and propose an appropriate maintenance strategy for the Tuber machine. The research employs the Failure Mode and Effects Analysis (FMEA) method to evaluate potential failure modes and their impacts. Based on the Risk Priority Number (RPN) analysis, four critical components were identified as the primary contributors to machine downtime, namely the differential gear, bearing, tear-off mechanism, and cam roller. The proposed maintenance strategy for the Cutting Unit of the Tuber T-645M machine is preventive maintenance, consisting of 28 scheduled component replacements and 38 maintenance activities to improve machine reliability and reduce downtime.]]>
