PERBAIKAN INSTRUKSI KERJA PATROLI MESIN TENUN SHUTTLE UNTUK PENINGKATAN EFISIENSI PRODUKSI

Abstract

In general, the weaving manufacturing process at PT XYZ still has low productivity (79%), low efficiency (75%), and low product quality (grade C-). In fact, the company has implemented comprehensive quality control (on materials, processes and products) in the form of patrol inspection work instructions for shuttle loom machines. This research aims to improve or update existing work instructions so that they meet the rules of work instructions that are clear, detailed, easily accessible and comprehensive. Improvements to work instructions are chosen among a variety of other causes because the variables of work instructions and the people who carry them out are relatively easier to do and do not take long time. The selected sample includes 6 types of weaving machines in the production period from January to July 2024. The construction of woven fabrics that are the object of research is the manufacture of woven fabrics from cotton warp yarn and weft yarn with yarn number 40, end per inch 94, pick per inch 70, 50 inch fabric width, plain woven type and 100000 meter fabric length.This production batch needs 36 weaving machine shuttle-type for 49 days. After the work instructions were corrected and the operator was given training to be consistent and correct in carrying out work instructions, there was a change in the quality of weaving production at PT XYZ. The productivity value increased to 81%, the efficiency value increased to 76% and the product grade became C+ grade.
