To commemorate the International Day of Botanic Garden Education 2026, Banua Botanical Garden of South Kalimantan held an interactive educational workshop under the global theme “Climate Action Through Education in Botanical Gardens” with the subtheme “Utilization of Kalimantan Medicinal Plants as Alternative Herbal Medicine and the Conservation of Pupur Bangkal.”

Held at the ex situ conservation area of Banua Botanical Garden, the event brought together researchers, environmental educators, herbal practitioners, conservationists, representatives from the Health Department, academics, vocational high school students in pharmacy and agribusiness, and young participants. In his remarks, the Head of Banua Botanical Garden emphasized the growing role of botanical gardens as centres of conservation and environmental education that contribute to addressing climate challenges. He highlighted the importance of preserving Kalimantan’s medicinal plants and strengthening local knowledge as part of sustainable solutions for the future.

The workshop explored the scientific and cultural value of Bangkal (Nauclea subdita (Korth.) Steud.), traditionally used as the main ingredient of Pupur Bangkal, a traditional cooling powder that reflects environmentally friendly local practices.

Participants were also introduced to medicinal plants from the garden’s collection, including tabat barito (Ficus deltoidea Jack) and mahkota dewa (Phaleria macrocarpa (Scheff.) Boerl.), to promote health resilience and biodiversity conservation.

Activities included exploration and identification of medicinal plants, a live product demonstration of bangkal powder and herbal beverages, and an interactive talk show on integrating indigenous knowledge into environmental education. Through this celebration, Banua Botanical Garden reaffirmed its commitment to becoming an inclusive natural classroom that inspires climate action through education rooted in Banua culture.
