Abstract

Setiap perusahaan berusaha memberikan layanan terbaik kepada pelanggan dengan menyerahkan produk tepat waktu. Oleh sebab itu, faktor kualitas dan lead time produksi merupakan faktor yang perlu diperbaiki secara terus-menerus melalui penerapan strategi internal yang tepat. Penelitian ini menggunakan pendekatan konsep lean manufacturing untuk mengidentifikasi waste sepanjang value stream guna menemukan aktivitas yang tidak memberikan nilai tambah (non-value-added activities). Pada tahap awal, digunakan Big Picture Mapping untuk menggambarkan keseluruhan aliran proses, kemudian Process Activity Mapping digunakan untuk mengidentifikasi aktivitas value-added, non-value-added, dan necessary but non-value-added. Selanjutnya, Quality Filter Mapping digunakan untuk mengetahui secara lebih rinci permasalahan kualitas, khususnya jenis defect yang terjadi. Pada tahap akhir, Total Productive Maintenance (TPM) diterapkan untuk mengurangi defect melalui pengukuran Overall Equipment Effectiveness (OEE). Analisis sensitivitas OEE terhadap operating time, cycle time, dan defect dilakukan untuk mengetahui faktor yang paling berpengaruh terhadap peningkatan nilai OEE. Hasil penelitian menunjukkan bahwa cycle time merupakan faktor yang paling berpengaruh terhadap nilai OEE. Penurunan cycle time sebesar 10% dapat meningkatkan nilai OEE sebesar 10,20%.

Every company strives to provide the best possible service to its customers by delivering products on time. Therefore, product quality and production lead time are key factors that need to be continuously improved through the implementation of appropriate internal strategies. This research applies the lean manufacturing concept to identify waste throughout the value stream and determine activities that do not add value (non-value-added activities). In the initial stage, Big Picture Mapping is used to describe the overall process flow. Process Activity Mapping is then used to identify value-added, non-value-added, and necessary but non-value-added activities. Subsequently, Quality Filter Mapping is used to identify quality problems in greater detail, particularly the types of defects that occur. In the final stage, Total Productive Maintenance (TPM) is applied to reduce defects through the measurement of Overall Equipment Effectiveness (OEE). An OEE sensitivity analysis of operating time, cycle time, and defects is conducted to determine the factor that has the greatest influence on OEE improvement. The results indicate that cycle time is the most influential factor affecting the OEE value. A 10% reduction in cycle time can increase OEE by 10.20%.
