Abstract

Competition in the industry makes manufacturing companies do continuous improvement of production in order to achieve good quality. PT. XYZ is a company engaged in the manufacturing industries that produce granite tile. The problems that often arise on the production floor, especially in the process of sorting and polishing that is, the high defect products produced in the process. The purpose of this study is to minimize damage to the product on the S & P, Useful and finished product quality improvement plans. To support solving this problem, researchers used a method approach Root Cause Analysis (RCA). In the histogram obtained from the check sheets, Pareto diagrams visible damage in the S & P damage type of disability the most dominant is the Crack (57%), followed Thick (18%), Glaze Drop (11%), Black Coring (8%), and the last is the Scraper Defect (6%). From the research, a result that most of the damage is Crack. Factors causing these defects are the factors that cause deviations quality raw materials such factors, factors working methods irregularities in the implementation of the work, a factor that is less engine preventive maintenance, factor of fewer operators do not obey the standard factory operations. From the productivity results in the S & P, generate some suggestion in terms of minimizing the product is defective is implementing kaizen. Keywords: Root Cause Analysis (RCA), Application of Process Improvement, Kaizen, 5S, Granite Tile.

Abstract

The high changeover activity process for changing products causes the output produced by the loss Tabelt printing section to not meet the target, in data for September - December 2023 with total output only reaching 90.22%. This percentage is still less than the production standard set by the company which must reach 98%. Single Minute Exchange of Die (SMED) is a method from Lean Manufacturing that is used to reduce time in the setup/changeover process. Therefore, this research was carried out using the single minute exchange of dies (SMED) method. This research aims to determine the factors that influence the length of changeover time and make improvements using the Single Minutes Exchange of Dies (SMED) method. The total standard time for the changeover process obtained was 39581.7 seconds. before applying the SMED method, the changeover process had a total of 15 activities, with 13 internal activities and 2 external activities with an average total time of 39581.7 seconds. After implementing the SMED concept, it resulted in a total of 13 activities for the changeover process, 10 internal activities and 3 external. The simulation results of the proposed improvement have a total time of 30717.2 seconds with a reduction percentage of 22%. The results of the analysis using FTE changeover activities before and after implementing the SMED method, the total FTE was 1.57. Meanwhile, after implementing SMED, the total FTE was 1.2 with Normal information. Keywords: Changeover, Single Minute Exchange of Die (SMED), Stopwatch Time Study, Fishbone Diagram, Internal and external activities, FTE

Abstract

In line with technological advancements and increased consumer expectations, quality has become a key factor in the service industry. PT. XYZ, which operates in the aircraft maintenance field, faces the challenge of reducing defects in the aircraft painting touch-up process. This research aims to reduce these defects using the DMAIC method. The DMAIC phases include define, measure, analyze, improve, and control. In the define phase, it was found that dust defects were the most dominant. Initial measurements showed an average DPMO (defects per million opportunities) of 12,129 and a sigma of 3.773. Analysis using the Ishikawa diagram identified the root causes of the problem, and FMEA helped determine the priority root causes that needed immediate improvement. The main causes of the aircraft paint touch-up defects were material cleaning that left fibers on the surface to be painted, and the spray gun being in an un optimized condition for use. Suggested improvements included procuring the appropriate cleaning materials and implementing a preventive maintenance checklist for the spray gun. The implementation of these improvements showed a reduction in dust defects, with the DPMO dropping to 3,477 and sigma increasing to 4.209. These results demonstrate that the improvements made were effective in reducing defects and enhancing painting quality.Keywords: DPMO, sigma, DMAIC, dust defects, aircraft painting.
