\u201cThis research underscores the importance of an interdisciplinary approach to protecting D. pugerensis, a relict species adapted to semi-arid karst forests yet highly sensitive to habitat disturbance,\u201d Aulia stated. She also proposed conservation strategies such as habitat protection, control of invasive species, as well as vegetative propagation and tissue culture techniques.<\/p>\n\n\n\n
The vegetation study results revealed high biodiversity in the habitat of D. pugerensis, with 90 species from 85 genera and 35 families, comprising more than 1,300 individuals. However, more than half of the species were represented by only one to two individuals, indicating a community structure that is highly vulnerable to local extinction. Molecular analyses using DNA barcoding and chloroplast genomes confirmed the identity of D. pugerensis and highlighted the potential of molecular markers for genetic conservation.<\/p>\n\n\n\n
Practical conservation efforts were also carried out through vegetative propagation using shoot cuttings, achieving a highest success rate of 57% and the fastest growth observed within 37 days. This approach demonstrates the potential of ex situ conservation as a complement to in situ protection in the species\u2019 natural habitat.<\/p>\n\n\n\n <\/p>\n\n\n\n Aulia emphasized that conserving D. pugerensis is not merely about saving a single species, but also about safeguarding an important evolutionary lineage as well as the ecological functions of tropical forests. \u201cProtecting this tree means preserving the forest ecosystem as a whole,\u201d she stated.<\/p>\n\n\n\n Thanks to this research, Aulia successfully earned her Doctoral degree with a Cum Laude distinction, under the supervision of Dr. Dra. Andi Salamah as promoter, and Dr. Iyan Robiansyah and Tety Maryenti as co-promoters. The open examination was attended by a panel of examiners who provided evaluations and scholarly feedback on her dissertation.<\/p>\n\n\n\n <\/p>","protected":false},"excerpt":{"rendered":" Depok, 7 Januari 2026 \u2013 Fakultas Matematika dan Ilmu Pengetahuan Alam Universitas Indonesia (FMIPA UI) menggelar sidang terbuka promosi doktor program studi Biologi dengan promovendus Aulia Hasan Widjaya.
