Abstract

PT. Trias Indra Saputra is a manufacturing company engaged in the production of cable support systems. One of the products it produces is a cable ladder. The problem that occurred was that it was discovered that there was a non-compliance with quality standards (defects) in the cable ladder product which exceeded the tolerance limit set by the company, namely 5%. Of the total 45,876 parts produced, there were 3,344 cable ladder units that were defective. This research aims to determine the most dominant types of defects and identify the causal factors for priority treatment. The methods used in this research are DMAIC and FMEA. The research results show that the most dominant type of defect in cable ladder products is chipped HDG with a percentage of 52%. In 2023, the DPMO value will be 14,500 with a sigma level value of 3.68. Based on calculations using FMEA, the most potential causal factors were obtained, namely that the temperature and duration of immersion did not comply with the RPN value of 392 and the condition of the product surface was less than clean with an RPN value of 294. The recommended improvements were: create an SOP for hot dip galvanized coating, create a list of hot dip galvanized coating provisions, dip galvanized based on the thickness of the material, as well as the temperature and duration of immersion, create an inspection report form, create an SOP control list.
