A Grade 10 learner of Paul Roos Gymnasium is preparing to showcase his pioneering agricultural research on the world stage as he joins three fellow South African learners at the prestigious World Innovative Science Project Olympiad in Bali next week.
Albertus Willem van Niekerk, known as Wium, will present his award-winning study on sustainable citrus farming at the international competition, which takes place from Wednesday 10 to Saturday 13 December.
The young scientist’s research project, entitled “In vitro growth inhibition of Penicillium digitatum by lavender oil”, investigates whether lavender essential oil could serve as an environmentally friendly alternative to chemical fungicides in citrus production.
Praise for innovation
Van Niekerk’s controlled experiments demonstrated that higher concentrations of lavender oil deliver antifungal results comparable to imidazole, a conventional chemical treatment.
His findings offer a promising solution for sustainable postharvest disease management, addressing growing concerns about chemical residues in food production while maintaining crop protection efficacy.
The selectors praised Van Niekerk’s work for its scientific rigour, agricultural relevance and practical application in South Africa’s vital citrus industry.
The Stellenbosch learner will be joined by three other Gold medallists from the Eskom Expo International Science Fair: Dzunisa Chauke from Khanyisa Education Centre, who developed an AI voice-classification system; Milla Vorster from Curro Durbanville, whose work focuses on 3D bioprinting of vascularised organs; and Ismaail Hassen from Greenside High School, who created an assistive navigation device for visually impaired individuals.
on global stage
The delegation, led by Jane Wasonga, Eskom Expo Johannesburg Regional Science Fair director, will represent SA at the annual competition organised by the Indonesia Scientific Society. The event brings together young scientists from around the globe to present their research and innovations.
Mologadi Motshele, acting CEO of the Eskom Development Foundation, emphasised the importance of encouraging young people’s participation in science, technology, engineering, mathematics and innovation (STEMI) fields. “By developing a strong pathway of skilled and enthusiastic scientists and innovators through the Eskom Expo for Young Scientists, we can build a more promising future for South Africa.”
Parthy Chetty, Eskom Expo executive director, expressed pride in the delegation’s achievements. “SA proudly sends four exceptional learners to the International Science Fair in Indonesia. Their achievement reflects strong mentorship, community support and the power of science education to transform lives.”
