Improving the Loading and Unloading Process Efficiency with Lean Manufacturing Approach using Value Stream Mapping in Jakarta Container Yard

Abstract

Facilities and infrastructure of maritime logistics activities such as ports, vessels, and containers are important indicators for developing national export-import activities. Maritime Logistics activities in container terminals has a big problem of dwelling time while apparently there are also bigger problems in Container yards. This leads to process and time efficiency problem. Container utilization can be improved in the loading and unloading process at Container Terminals and Container Yards. The Loading and Unloading processes at container yards happen to be the longest duration of all logistics activities. Therefore, increased loading and unloading efficiency at container yards are needed as an effort to increase export-import activities. The study was conducted by observing the loading (lift-on) and unloading (lift-off) process flow to identify waste using the Value Stream Mapping (VSM) method. Waste of Waiting is identified both in Loading and Unloading processes. VSM design results in an increased level of efficiency up to 84.89% for the unloading process and 80.51% for the loading process. The VSM method is needed as waste identification and efficiency improvement efforts for container service in Jakarta container depot. The VSM method is needed as waste identification and efficiency improvement efforts for container service in Jakarta container yard.
