Profile of Dr. Johannis W. D. Therik ST., MT.

A university lecturer and researcher focused on energy, environment, and agricultural innovation.

Dr. Johannis W. D. Therik is a university lecturer and researcher whose work sits at the intersection of energy, the environment, and agriculture.

His research asks a practical question: how can communities in East Nusa Tenggara farm productively without depleting the resources they depend on? That has led him to field trials of organic fertilizer, soil restoration projects, and work on low-cost inputs that smallholders can actually afford.

As Rotenia’s lead researcher, he helps design the demonstration plots and measurement methods behind our case studies, and he mentors students and farmers who want to run their own trials.

His approach is consistent throughout: test in real conditions, measure carefully, and share the results openly.
