One analytical mindset

Two disciplines.
One standard of evidence.

Engineering asks whether a system can work. Investing asks whether a business can create durable value. Both require clear assumptions, rigorous analysis, and respect for uncertainty.

I am a Professor of Renewable Energy Conversion Engineering Technology 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.

Investment perspective

Long-term ownership begins with disciplined analysis.

I approach public equities as a long-term owner. My research process focuses on business quality, industry structure, financial statements, valuation, risk, and capital allocation across Indonesian and U.S. markets.

My background in energy systems informs how I evaluate transition pathways, commodity cycles, and capital-intensive businesses.
