Abstract

Industrialization is an alternative development model needed by the country to spur economic processes. Apart from accelerating the economy, the development of industrialization also has impacts that need to be watched out for, including the presence of a waste industry. One of the companies that manages the waste, namely PT. AJU is also a service company for the procurement and sale of metal waste (metal scrap) in Karawang. The metal scrap studied is canned metal scrap, which is wasteful in the procurement and sales process. So that efforts are made to minimize the waste that occurs. This research uses the Value Stream Mapping method with VALSAT analysis. Based on the research results, the most common types of waste are waiting (28%), inventory (24%), and movement (20%). Then the mapping tools that will be used based on the results of converting the questionnaire scores into the VALSAT matrix are Process Activity Mapping (33%), Supply Chain Response Matrix (20%), and Demand Amplification Mapping (17%). The Value Added Ratio (VAR) before the repair has a value proportion of 3%, while after the repair analysis the VAR value becomes 9%.

Abstract

PT. Papertech is a company engaged in manufacturing that produces core board type paper. The process of making core boards is a continuous process where every day the company always produces coreboards that are not just one type of core board. Given these problems, one way to minimize defective product rosters is to use the six sigma method analysis and failure mode and effect analysis. Research analysis using the six sigma method goes through several stages, namely the Define stage, which defines a general picture regarding the influence of the process on customer service. Meanwhile, at the Measure stage, namely Critical To Quality, Control Map and DPMO and sigma calculations for the 3 highest causes of defects, namely low plybond, low gsm, low cobb. The DPMO value in November 2023 is 450000 with a sigma value of 1.626, December 2023 is 422535 with a sigma value of 1.695, January 2024 is 474934 with a sigma value of 1.563, February 2024 is 560000 with a sigma value 1,349, March in 2024 it will be 540,000 with a sigma value of 1,400. The Analyze stage is to determine the main cause of the defect using fishbone. The Improve stage is to make improvements using Failure Mode and Effect Analysis (FMEA) according to the highest Risk Priority Number (RPN) value level of 540 for material, 189 for machine, 540 for human and 61 for method. The Control stage is documenting the quality improvement results stage
