One analytical mindset

Two disciplines.
One standard of evidence.

Renewable-energy research asks how systems convert heat, fluid flow, and resources into useful power. Strong engineering requires clear assumptions, rigorous analysis, and respect for uncertainty.

I am a Professor of Renewable Energy Conversion at Universitas Sebelas Maret, Indonesia. My research spans geothermal systems, thermodynamics, Organic Rankine Cycle technology, energy and exergy analysis, renewable-energy conversion, and system optimization.

I earned my doctorate in Earth Resources Engineering from Kyushu University, where my research examined geothermal power-plant performance, exergy, and silica-scaling behavior. I also contribute to international scientific publishing as an editor and reviewer.
