Jupen Sastro Nababan
Summary
Learn in every moment" and "Be useful" are principles I live by to this day. I started as a non-staff (mechanic) and was trusted all the way up to staff (foreman/supervisor).
One memorable moment was when our team won first place in the All Contractor Partners award from the Owner (Berau Coal) and also at Adaro Indonesia. The work area was accident-free and K3 implementation was orderly.
My life motto is: "What can be done today, do it, don't wait for tomorrow."
