Abstract

Proses manufaktur yang efisien dan terstandardisasi memainkan peran penting dalam memastikan kualitas hasil produksi memenuhi standar yang ditetapkan. Namun, kompleksitas dan variasi produk yang tinggi di bidang manufaktur menimbulkan tantangan dalam menjaga kualitas dan meminimalkan kesalahan. Studi mengungkapkan bahwa tingkat cacat rata-rata dalam proses manufaktur di Indonesia adalah 31%–jauh dari tingkat cacat yang ideal atau ke arah zero defect. Temuan menunjukkan bahwa kesalahan manusia (human error) pada proses produksi yang dilakukan secara manual pada PT Spectrum Unitec memberikan kontribusi yang signifikan terhadap terjadinya cacat. Meskipun persentase cacat terbesar hanya 0,2% dari total produksi, kerugian finansial yang ditimbulkan cukup besar. Penelitian ini bertujuan untuk menyelidiki hubungan antara kelelahan (fatigue), tindakan tidak aman (unsafe acts), dan kesalahan manusia (human error), serta dampak potensial dari moderasi shift terhadap hubungan tersebut. Pengumpulan data dilakukan melalui penyebaran kuesioner kepada operator yang bekerja pada shift 1 dan shift 2. Hasil pengolahan data menggunakan aplikasi SmartPLS menunjukkan bahwa fatigue dan unsafe acts secara statistik berpengaruh positif dan signifikan terhadap human error. Hal ini ditunjukkan dengan perolehan p value < 0,05 pada kedua hubungan yang dimodelkan pada konstruk. Selain itu, unsafe acts juga terbukti secara statistik memediasi parsial hubungan fatigue dengan human error, yang salah satunya dapat juga dilihat berdasarkan perolehan p value < 0,05. / Efficient and standardized manufacturing processes play an important role in ensuring the quality of the output meets the established standards. However, the high complexity and variety of products in manufacturing impose challenges in maintaining quality and minimizing errors. Studies uncover that the average defect rate in manufacturing processes in Indonesia is 31%–a far cry from the ideal defect rate or towards zero defects. Findings show that human error in the manual production process at Spectrum Unitec Inc. significantly contributes to the occurrence of defects. Although the largest percentage of defects is merely 0.2% of total production, the financial loss incurred is considerable. This study aims to investigate the relationship between fatigue, unsafe acts, and human error, and the potential impact of shift moderation on the relationship. Data collection was conducted through distributing questionnaires to operators working on shift 1 and shift 2. The results of data processing using the SmartPLS application show that fatigue and unsafe acts have a statistically significant and positive effect on human error. This is indicated by the obtaining of p-value <0.05 in both relationships which have been modeled on the construct. Other than that, unsafe acts are also proven statistically to be partially mediating the relationship between fatigue and human error, one of which can also be identified based on the acquisition of p-value <0.05.
