Tripatra has created a proactive safety culture  which focuses on three elements : worker, works, and environment.
  • Safe worker is healthy worker, competent, and behaviorally safe.
  • Safe work is for the work that is executed with proper procedure, safe equipment operation, competent operator, and safe storage, handling and usage of hazardous material.
  • Safe environment if these is no unauthorized person in the area, environmental aspect in control and  all environmental hazard in control.

Safe operation is maintained by the implementation of SHE management system which is driven by strong commitment and leadership.



One of the social concern is health issue. Tripatra often initiates medical program for community live nearby its sites. Realizing that access to proper medical treatment can be a privilege, Tripatra to bridge the gap starting from the nearest environment.

Another unavoidable health issue a for country living in the ring of fire can come from natural disaster. Affected by natural disaster caused by volcanic eruption, Tripatra gave fast and responsive act for community in Jogjakarta back in 2010.


Education is essential for development because it empowers people to have better and prosperous life. Believe in that, Tripatra put major concern in local and national education. Tripatra supports the schools facilities in areas nearby its sites such as Bojonegoro, Gunung Salak Bogor, and Garut. Proper infrastructure advantages better learning and teaching environment.
