MINIMASI KASUS OVERTONNAGE PADA AKTIVITAS OUTBOUND MELALUI PENDEKATAN DMAIC (STUDI KASUS: WDC-UNILEVER)
Abstract
As a leading FMCG company in Indonesia, Unilever faces challenges in efficiently
managing product inventory and ensuring product availability in the market. One of the
problems encountered by Unilever in its outbound activities at the West Distribution Center
is overtonnage. Overtonnage happens when the total weight or total volume of the products
being handled exceeds what it actually is planned, causing inefficienty. The purpose of this
study is to analyze the impact of overtonnage, to determine the contributing factors, and to
find solutions to reduce overtonnage cases. Using the Define, Measure, Analyze, Improve
and Control (DMAIC) approach from Six Sigma, this study assisted Unilever Indonesia to
find the root causes of the overtonnage problem and to provide a systematic solution. The
results revealed that overtonnage’s negative impacts include double handling costs,
potential lost sales, and decreased warehouse productivity. While the factors causing
overtonnage include Stock Keeping Unit (SKU) mix, layout of goods on trucks
(planogram),different truck size that is used in distribution, the lack of update in master
data, as well as some issues in the stage of planning. The proposed solution involves
updating the master data regularly based on the actual dimensions, changing the
dimensional check procedure, and updating the reporting system of overtonnage cases
