Abstract

Yarn spinning is an important aspect of the world of textiles. This is because spinning is the main focus of the textile industry sub-sector. Therefore, when yarn products are not suitable, this can have an impact on consumers and companies. This research then aims to look at the problem of the non-standard strength index of 30 TR 65/35 process cone threads using a problem-solving method through the PDCA concept. This research will be carried out using semi-quantitative methods. The analysis method used incorporates concepts from FTA (Fault Tree Analysis) and PDCA. The results of this research then found that the case study at PT X identified the main cause of non-standard tensile strength of 30 TR yarn as a combination of material suitability, machine condition, and environmental factors which had the most significant impact. The use of SFX brand polyester fiber and SPV brand rayon as raw materials, as well as an appropriate waste reuse sorting process, has been proven to increase the quality of the tensile strength of the yarn. Errors in twist values and suboptimal machine maintenance were also found to contribute to a decrease in yarn tensile strength. Production environmental conditions, such as high humidity, have a negative effect on yarn strength. An effective solution to this problem was found by adding wax to the thread, increasing its tensile strength by 7%.

Abstract

The spinning industry is an important part of the textile sector that faces efficiency challenges due to the large amount of waste in the production process. This study aims to analyze the implementation of Lean Manufacturing as a strategic approach to improving production efficiency in one of the medium-scale spinning companies in West Java. Using a qualitative descriptive method, data were obtained through direct observation, in-depth interviews with six key informants, and analysis of company documents. The results of the study indicate that the application of Lean principles such as 5S, Just-In-Time (JIT), Total Productive Maintenance (TPM), and Visual Management can reduce waiting time between processes by 55%, reduce the frequency of machine breakdowns by 62.5%, and increase the orderliness of the work area by 68%. Even so, the implementation of lean is not free from challenges such as the mismatch of production schedules with machine readiness, resistance to work culture from senior employees, and lack of in-depth understanding of lean tools. This study confirms that the success of Lean Manufacturing depends not only on the tools used, but also on the readiness of the organizational culture and supporting information systems. These findings provide practical contributions to the development of efficient and sustainable operational management strategies in the spinning industry, and offer recommendations in the form of integrated training, integration of production information systems, cross-departmental evaluation, periodic lean audits, and performance-based reward schemes.
