Abstract
Keberhasilan penerapan strategi logistik dapat dilihat dari peningkatan tingkat kepuasan pelanggan yang menunjukkan efektivitas dalam memenuhi permintaan dan kebutuhan pelanggan. PT Z menghadapi masalah berupa aktivitas pergudangan yang tidak efisien. Penelitian bertujuan untuk mengidentifikasi jenis-jenis pemborosan (waste) yang terjadi dalam aktivitas operasional pergudangan di PT Z dan menganalisis akar penyebab dari setiap pemborosan menggunakan pendekatan Lean Warehousing. Kemudian, merancang usulan perbaikan untuk mengurangi waste menggunakan metode Lean Warehousing. Desain penelitian yang digunakan menggunakan metode kuantitatif deskriptif dengan cara menggambarkan objek penelitian pada saat keadaan sekarang berdasarkan fakta-fakta sebagaimana adanya, kemudian dianalisis dan diinterpretasikan. Didapatkan persentase Non Value Added sebesar 31,25 % dan persentase Necessary Non Value Added sebesar 68,75 %. Waste dominan teridentifikasi pada Waste Motion, Overprocessing, dan Defect. Hasil Five Why Analysis mengungkap akar permasalahan waste yaitu kurangnya prioritas manajemen terhadap layout yang efisien, fokus pengukuran kinerja operasional lebih cenderung pada kecepatan loading barang, fokus pengukuran kinerja operasional lebih dominan pada kecepatan yang diturunkan, dan kepala operasional tidak mengajukan usulan perbaikan. Dilakukan pemetaan Future Process Activity Mapping dan Future Value Stream Mapping. Hasil usulan perbaikan menunjukan penurunan NVA Sebesar 19,47 % dan Kenaikan NNVA Sebesar 19,47%. Lead time proses mengalami penurunan sebesar 420 detik atau 7 menit. Pihak PT Z menilai usulan perbaikan yang diajukan tepat dan efisien dalam menjawab permasalahan di lapangan. The success of logistics strategy implementation can be observed through the increase in customer satisfaction, which indicates effectiveness in meeting customer demands and needs. PT Z is currently facing inefficiencies in its warehouse operations. This study aims to identify the types of waste occurring in the warehouse operational activities at PT Z and to analyze the root causes of each waste using the Lean Warehousing approach. Furthermore, this research proposes improvement recommendations to reduce waste through the application of Lean Warehousing methods in PT Z’s warehouse operations. The research design used is descriptive quantitative, by describing the research object in its current state based on existing facts, which are then analyzed and interpreted. The results show a Non-Value Added activity percentage of 31.25% and a Necessary but Non-Value Added activity percentage of 68.75%. The dominant wastes identified were Waste Motion, Overprocessing, and Defect. The results of the Five Why Analysis revealed root causes such as the lack of management priority on efficient layout, operational performance measurement that focuses more on loading speed, decreased emphasis on comprehensive performance metrics, and the absence of improvement initiatives from the operations manage. Future Process Activity Mapping and Future State Mapping were conducted. The proposed improvements led to a 19.47% decrease in NVA and a 19.47% increase in NNVA. Additionally, process lead time was reduced by 420 seconds or 7 minutes. PT Z considers the proposed improvements to be appropriate and effective in addressing the issues in the field.
