| Summary: | PT. Dirgantara Indonesia (PTDI) is a State-Owned Enterprise (SOE) in the
segment of aerospace industry. In accordance with its vision to lead the medium &
light turboprop aircraft market and to become a reference for aerospace companies
in the Asia Pacific region by optimizing commercial and industrial competencies.
In achieving these vision, it is necessary to increase the capacity and efficiency of
the production process, one of the steps taken is to apply Lean manufacturing,
hereinafter referred to as lean.
To build lean strategies in PTDI that have a variety of production systems ranging
from job shops and batch shops in the Detail Part Manufacturing (DM) area, job
shops and flow shops in the Component & Assembly (CA) area, and flow shops in
the Final Assembly Area (FD) area, a lean assessment method is needed that is able
to assess the implementation of lean practice in multi-plant. This research conducts
the development of lean asessment tools in the aerospace industry context, focused
on lean practices implementation on manufacturing area, and eliminating lean
enabler.
Base model for the lean practices were developed from nine determinants model of
Karlsson & Åhlström (1996) and 22 manufacturing practices of Shah & Ward
(2003). Identification and elimination of lean enabler was performed based on
Oehmen (2012). After validated against PTDI’s production system, a total of 7
variables resulted as instrument of assessment.
Indicators of assessment are valid and reliable in evaluating the implementation of
lean in the aerospace industry. The developed model has been proven capable to
identify lean implementation level of PTDI, which has plants with various
production system characteristics. By observing degree of adaptation (DoA) of
each lean practice against degree of leanness (DoL), it was identified two lean
practices with DoA level below DoL level.
