Renewable energy systems
Geothermal conversion, thermodynamics, Organic Rankine Cycle systems, heat recovery, and energy and exergy analysis.
Renewable Energy Conversion Research Geothermal Systems Thermodynamics & ORC
I work on renewable-energy systems research, with a focus on geothermal power, Organic Rankine Cycle technology, thermodynamics, energy and exergy analysis, and research-informed engineering education.
Analytical lens
One analytical mindset
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.
Geothermal conversion, thermodynamics, Organic Rankine Cycle systems, heat recovery, and energy and exergy analysis.
Thermodynamic modeling, performance evaluation, uncertainty-aware assumptions, and system-level comparison for renewable-energy technologies.
Profile
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.
