UMP Big Cleaning Day was launched on June 6, 2013. Gotong-royong was one of the activities that were required to be carried out in the planning calendar of every PTJ, a move to make sure that they have a good environment programme.  It is also the beginning to an initiative and to acculturate the 5S Practices that put emphasis on quality and organised working area, and to ensure that actions listed under the 5S Practises are actively implemented.
