Abstract

This research aims at quality measuring of steelfast trusses production process at PT. Kuda-kuda Total Prima based on Six Sigma concept. The study also indentifying divergences or defects of production processes. Each of the divergences has found will informated to the company as recommendations for process improvement. The research using cutting detail, roof layout, trusses detail and some of steelfast trusses production procedures as instrument for identifying data. Study obtains data with observations. The observation divided based on production places, they are fabrication and installation process. Total of data has collected are 1575 point, they are 514 point of materials, 288 point of joints, 65 point of stationings, 210 point of splices and 288 point of bracing. Result of the study show 255 data that idenficated as defect. Defect just occur at joints, splices, and bracing. Number of defect are equivalent 161904,76 DPMO (Defect Per Million Opportunities). This result able to applicated on sigma level, and then get the quality measuring of steelfast trusses production process achieve 2,6 sigma.
