The SIGAP Mechanic Program (Safe, Initiative, Agile, Secure, And Professional) to Enhance Occupational Safety Culture and Prevent Accidents at PT Antareja Mahada Makmur Workshop

Abstract

The SIGAP Mechanic Program is an initiative to improve the occupational safety and health (K3) culture, implemented in the workshop area of PT Antareja Mahada Makmur at the Jobsite Mifa Bersaudara. This program emerged from a high number of unsafe actions and a history of incidents with the potential to cause serious accidents. Through a systematic approach based on the QCC method, the team identified problems, analyzed root causes, and set goals to foster a more disciplined, safe, and professional work culture. The improvement process involved safety training, strengthened communication between supervisors and mechanics, implementation of 5Rs, increased compliance with personal protective equipment (PPE) usage, continuous inspections, and creation of a WhatsApp-based reporting system to expedite follow-up on findings. All activities took place during the June–July 2025 period and involved synergy between the SHE and PLANT departments. Evaluation results showed a significant increase in K3 compliance, a reduction in unsafe actions, an improved assessment score for the mechanical team, and zero incidents during the program period. This improvement positively impacted quality, safety, cost efficiency, and worker morale. In addition to eliminating potential injuries, the program succeeded in reducing operational risks and driving cost efficiencies in accident handling. Ultimately, the implementation of SIGAP Mechanics proved effective in building a strong and sustainable K3 culture.
