About Dr. Whika Febria Dewatisari

Researcher & educator

Science grounded in curiosity, service, and access.

I am Dr. Whika Febria Dewatisari, S.Si., M.Si., an Associate Professor (Lektor Kepala) in Biology at Universitas Terbuka. My work connects plant science, phytochemistry, microbiology, and open distance education.

In the laboratory, I investigate bioactive compounds and the antibacterial and antibiofilm potential of medicinal plants. In the classroom, I design approachable learning experiences that help distance learners ask better questions, test ideas, and build confidence in science.

Research focus

• Plant Phytochemistry & Secondary Metabolites: Extraction and TLC/GC-MS screening of flavonoids, saponins, tannins, and alkaloids from medicinal flora.
• Antibacterial & Antibiofilm Assays: Investigating cellular mechanisms of natural extracts (e.g. Sansevieria trifasciata) against pathogenic bacterial strains.
• Ethnopharmacology: Scientific evaluation of Indonesian herbal remedies like Wedang Uwuh and Mitragyna speciosa.
• Open & Distance Learning Pedagogy: Innovating virtual and distance practical modules for biology students across Indonesia.
