Abstract

Pinus Jantho Forest (PJF) Nature Reserve has unique characteristics and distinctive ecosystem that plays an important role in the preservation of germplasm and the protection of natural resources. The sustainability of the PJF Nature Reserve is strongly determined by vegetation of its constituents. Therefore, an effort is needed to help its management properly, one of which is by knowing the diversity of plants that make up the community in PJF Nature Reserve. The purpose of this research is to analyze the composition and diversity of plant species in PJF Nature Reserve. Data collection and sampling were done using multiple square method. The plots were laid out by systematic sampling. PJF Nature Reserve composed of 111 species from 46 family. The seedling and understorey have the highest number individuals (1028 in total). Then there are 240 individuals at sapling level, 108 individuals at pole, and 72 individuals for tree.  The Euphorbiaceae family has the largest number of species (11 species). The highest Important Value Index (IVI) for seedlings and understorey, sapling and pole, and tree respectively were Chloranthus elatior (11.09%), Piper aduncum (21.90% and 19.32%), and Pinus merkusii (25.52%). The Diversity Index indicates a high level of plant species diversity (3.25-3.63).

Abstract

Tumbuhan Aren (Arenga Pinnata (Wurmb. Merr) memiliki aktifitas farmakologis dan telah dimanfaatkan sebagai obat diberbagai daerah dengan cara yang beragam. Masyarakat di Kabupaten Aceh Tengah sudah sejak lama memanfaatkan aren sebagai obat tradisional, namun pengetahuan mengenai kegunaannya sebagai obat belum terdokumentasi dengan baik. Penelitian ini bertujuan untuk memperoleh informasi tentang kegunaan tumbuhan aren sebagai obat oleh masyarakat lokal. Penentuan Lokasi penelitian dan responden dilakukan secara Purposive Sampling, sedangkan untuk kajian etnofarmakologi menggunakan Metode Participatory Rural Appraisal (PRA). Masyarakat Kabupaten Aceh Tengah memanfaatkan tumbuhan aren sebagai sumber obat-obatan untuk menyembuhkan 31 jenis penyakit. Selain penggunaan tujuh bagian tumbuhan, hasil produksi tumbuhan aren seperti air nira dan gula aren juga berkhasiat obat. Bagian tumbuhan yang paling banyak digunakan adalah buah (33,52%), sedangkan untuk hasil produksinya adalah air nira (64,29%).  Teknik pengolahan tumbuhan aren sebagai obat paling banyak digunakan dengan cara direbus (16 penyakit). Cara penggunaan tumbuhan aren paling banyak dikonsumsi secara oral. Tumbuhan aren di kabupaten ini merupakan tumbuhan liar yang populasinya saat ini menurun drastis akibat ditebang (61,73%) dan serangan beruang (38,27%).
