ABSTRACT: The purpose of this paper is to apply value stream
mapping (VSM) for enabling leanness in Directorate Airworthiness and Aircraft
Operation, Directorate General of Air Transportation, Ministry of Transportation
Republic of Indonesia. A current state mapping is made to determine the
activities that provide value-added and non-value-added activities or waste.
Weaknesses in the current state process mapping will be analyzed and improved
in the future state mapping to obtain a better flow, faster and more
efficiently. The reduction of total lead time, makes total cycle time decrease
significantly, i.e. 69%, or from 94.5
to 29.5 days, while the process time is constant, i.e. 18 days. Future state mapping can reduce lead time and
increase cycle time efficiency. Current State Mapping shows weaknesses/waste
and is non value added. Current state shows quite a high lead time value, so
that cycle time efficiency is low. The efficiency value is 0.112 and after
future state mapping becomes 0.70. Lean service research in government
organizations has been the first time done in Indonesia.
