Abstract:
The automotive industry, including in Indonesia, has experienced rapid growth,
driving companies to continuously innovate to maintain competitiveness. PT
PN, a logistics company specializing in automotive distribution, faces challenges
related to high defect rates during loading and unloading processes, such as
scratches, dents, and waves on vehicle bodies. These defects lead to increased
operational costs, reduced time efficiency, and lower customer satisfaction. This
study aims to identify the root causes of product defects, analyze workers'
physical and mental workload using the NASA-TLX method, and propose
solutions to enhance operational performance. Data were collected through field
observations, interviews, and questionnaires involving 15 employees in the
outbound department. The results indicate that workers' mental and physical
workloads are classified as "high," significantly contributing to product defects.
Repair costs due to product defects amounted to IDR 125,850,000 during the
June–October 2024 period. The proposed recommendations include stress
management training, workload distribution optimization, improved safety
procedures, and enhancement of supporting facilities. Implementing these
strategies is expected to reduce defect rates, improve operational efficiency, and
help achieve the zero-defect target, thereby strengthening the company's
reputation in automotive logistics
