About Us
Who
We Are
PT. Trisakti Mekarmandiri (TMM) was founded in 1988 by a mechanical engineer from the University of Indonesia with more than 16 years of experience in building construction and development.

Established with the vision of independent and professional practice, the company began as PT. Trisakti Arta Mekar before later becoming PT. Trisakti Mekarmandiri, with its core focus remaining unchanged.
Since 1992, TMM has focused on developing skilled, responsible, and independent Indonesian professionals. The company’s growth led to the establishment of its dedicated office in Jalan Kedoya Duri Raya in 1994 and the expansion of its project scope and design-and-build capabilities.
Guided by gratitude and responsibility, TMM continues to strengthen its management, systems, and teamwork to improve efficiency, quality, and relationships with all business partners. The company remains committed to delivering successful projects and achieving sustainable, shared prosperity.
