About Tekalumni

A senior team that has built and run the plants it assesses.

PT Tekalumni Konsultan was founded in 1996 by the ITB Chemical Engineering Foundation and a group of ITB alumni. Three decades on, we remain an engineering house led by operators: people who have designed, built, commissioned, and run energy and chemical plants, and who now bring that judgement to feasibility, engineering, and independent assessment.

Who we are

Operators first. Assessors by experience.

We help energy and chemical players move from concept to bankable, buildable projects: feasibility, engineering, delivery, and independent assessment. Our work spans state-owned, multinational, and private clients, with a focus on green technologies and the low-carbon transition. What sets us apart is simple: our assumptions come from the field, not the textbook.

What we stand for

  • Operator-grade insight. We have built and run the plants we now study.
  • Independence. Objectivity, not advocacy, is our deliverable.
  • Full lifecycle. Study, engineering, and assessment in-house.
  • ITB pedigree. Founded by the ITB Chemical Engineering Foundation.
Since 1996

Three decades of engineering judgement, earned in the field.
