About REGEN

REGEN develops efficient energy systems, environmentally friendly refrigeration and renewable fuels for Indonesia’s energy transition.

Who We Are

The Energy and Environment Research Group (REGEN) is a research group in the Department of Mechanical Engineering, Faculty of Engineering, Universitas Indonesia. It is led by Prof. Dr.-Ing. Ir. Nasruddin, M.Eng. Our members study how to produce, convert, store and use energy with less waste and less harm to the environment.

Together, REGEN members have published more than 490 research outputs, with over 5,100 Scopus citations.

Vision

To be a leading research group in Southeast Asia for efficient and sustainable energy systems.

Mission

  1. Conduct high-impact research on energy systems, refrigeration, adsorption and renewable fuels.
  2. Educate engineers and researchers through undergraduate, master’s and doctoral programs.
  3. Transfer technology to industry, government and communities across Indonesia.
  4. Build partnerships with universities and industries in Indonesia and abroad.

What We Do

  • Energy system optimization. Thermoeconomic and exergy analysis of power plants, multi-objective optimization, and cascade refrigeration with CO2 and hydrocarbon mixtures.
  • Refrigeration and air conditioning. Natural refrigerants such as R290 (propane), absorption chillers, loop heat pipes for HVAC, and performance testing of air conditioners and heat pumps.
  • Heat transfer and two-phase flow. Boiling heat transfer, pressure drop and flow patterns in microchannels; ice slurry generators for fishing vessels.
  • Adsorption and gas storage. Activated carbon and bio-MOF adsorbents for methane storage, CO2 capture and adsorption cooling.
  • Biomass and waste-to-energy. Gasification of rice husk and sago waste, hydrogen-rich syngas, tar reduction, and hydrothermal carbonization of municipal waste.
  • Thermal energy storage. Biochar from oil palm empty fruit bunches and water-glycol storage for building cooling.

Facilities

REGEN members work in the laboratories of the Department of Mechanical Engineering, UI Depok campus, including test rigs for refrigeration, adsorption kinetics, two-phase flow visualization and biomass gasification.
