Abstract

Pteridophyta, a group of vascular cryptogams, demonstrate remarkable adaptability to a wide range of environmental conditions. Within this group, the genus Pyrrosia (Polypodiaceae) is particularly notable for its unique morphological adaptations and the presence of trichomes key features in taxonomic identification and species delimitation. This study investigates the morphological characteristics and trichome structures of Pyrrosia species growing in the vicinity of Andalas University, West Sumatra, Indonesia. Field sampling was conducted through systematic exploration in the Biological Garden of the Faculty of Mathematics and Natural Sciences, Andalas University. Specimens were collected and examined using a binocular light microscope (Sinher XSZ-107) to observe the morphology of primary vegetative organs roots, rhizomes, and leaves as well as trichome characteristics on the leaf surface. Three Pyrrosia species were identified: P. angustata, P. piloselloides, and P. adnascens. Distinct morphological differences were observed among them. The sterile leaves of P. angustata are lanceolate, while those of P. piloselloides and P. adnascens are oblong. The fertile leaves also vary: lanceolate in P. angustata, elliptical in P. piloselloides, and narrowly pointed in P. adnascens. A consistent feature across all three species is the presence of stellate (star-shaped) trichomes, a characteristic of taxonomic significance within the genus. The findings of this study contribute to a better understanding of morphological variation within Pyrrosia and reinforce the importance of micromorphological traits, particularly trichomes, in supporting species identification and classification within the Polypodiaceae.

Abstract

Kegiatan pengabdian masyarakat internasional ini merupakan bentuk kolaborasi akademik dan sosial antara Universitas Andalas (UNAND) dan Universitas Malaya (UM), yang turut melibatkan komunitas lokal seperti Bundo kanduang Kerapatan Adat Nagari (KAN) Limau Manis dan Ikatan Keluarga Minangkabau Malaysia (IKMM). Tujuan utama kegiatan ini adalah memperkuat hubungan kelembagaan melalui lokakarya biologi terapan dan pertukaran pengetahuan berbasis nilai-nilai budaya Minangkabau. Permasalahan yang diidentifikasi mencakup terbatasnya integrasi pengetahuan biologis dalam konteks lintas budaya dan kurangnya media komunikasi efektif antar komunitas akademik dan masyarakat. Dengan pendekatan partisipatif, kegiatan ini meliputi lokakarya tematik, diskusi ilmiah, serta pertunjukan budaya yang menampilkan artefak tradisional seperti piring hitam yang masih tersimpan dan relevan hingga kini di Museum Universiti Malaya. Hasil kegiatan menunjukkan peningkatan pemahaman peserta terhadap penerapan biologi dalam kehidupan sehari-hari dan penguatan jejaring kerja sama antara institusi pendidikan dan masyarakat adat. Pendekatan berbasis budaya lokal terbukti efektif dalam menjembatani perbedaan dan memperkuat komunikasi ilmiah lintas negara. Kegiatan ini memberikan kontribusi penting dalam mendukung diplomasi akademik, pelestarian budaya, dan pemberdayaan masyarakat melalui ilmu hayati.
