Abstract

PT Anugrah Insan Prima sebagai penyedia jasa logistik dan pergudangan
menghadapi permasalahan pada proses penerimaan barang seiring dengan
meningkatnya kebutuhan efisiensi untuk meningkatkan kualitas layanan di industri
logistik Indonesia, terutama pada aktivitas unloading yang belum berjalan efektif
dan efisien. Penelitian ini bertujuan untuk menganalisis dan memperbaiki
warehouse business process di PT AIPLOG menggunakan metode Lean Six Sigma
dengan pendekatan DMAIC (Define, Measure, Analyze, Improve, Control).
Pengumpulan data dilakukan melalui observasi langsung, wawancara dengan pihak
internal gudang, serta pengukuran durasi proses unloading selama periode Februari
hingga April 2025. Hasil awal menunjukkan rata-rata waktu unloading sebesar 43
menit dengan 8 kejadian melebihi batas toleransi 60 menit. Analisis Six Sigma
menghasilkan nilai DPMO sebesar 205.128 dengan level sigma 2,38 yang
mengindikasikan ketidakefisienan proses. Perbaikan dilakukan dengan menerapkan
sistem sloting truk, penyusunan SOP unloading, optimalisasi alat bantu dan tenaga
kerja, serta koordinasi lintas divisi. Setelah perbaikan, waktu rata-rata unloading
menurun menjadi 35 menit, keterlambatan menurun menjadi 2 kejadian, dan level
sigma meningkat menjadi 3,42. Dengan demikian, penerapan Lean Six Sigma
terbukti mampu meningkatkan efisiensi proses bisnis pergudangan, mengurangi
variasi, dan meningkatkan keandalan operasional di PT AIPLOG.
Kata Kunci: Lean Six Sigma, DMAIC, Unloading, Efisiensi Operasional, PT

Uncontrolled Keywords:	PT Anugrah Insan Prima, as a logistics and warehousing service provider, faces challenges in the goods receiving process in line with the increasing demand for efficiency to improve service quality in Indonesia’s logistics industry, particularly in unloading activities that are not yet effective and efficient. This study aims to analyze and improve the warehouse business process at PT AIPLOG using the Lean Six Sigma method with the DMAIC (Define, Measure, Analyze, Improve, Control) approach. Data were collected through direct observation, interviews with internal warehouse personnel, and measurement of unloading duration from February to April 2025. Initial results showed an average unloading time of 43 minutes, with 8 occurrences exceeding the tolerance limit of 60 minutes. Six Sigma analysisresulted in a DPMO of 205,128 and a sigma level of 2.38, indicating process inefficiency. Improvements were made by implementing a truck slotting system, establishing unloading SOPs, optimizing tools and manpower, and enhancing interdepartmental coordination. After improvements, the average unloading time decreased to 35 minutes, delays were reduced to 2 occurrences, and the sigma level increased to 3.42. Thus, the application of Lean Six Sigma proved effective in enhancing warehouse business process efficiency, reducing variation, and improving operational reliability at PT AIPLOG Keywords: Lean Six Sigma, DMAIC, Warehouse Business Process, Inbound, Operational Efficiency, PT AIPLOG.
