Abstract

Pranajiwa (Euchresta horsfieldii (Lesch.) Benn) is a medicinal plant, which is growing wild and it is regarded as a rare plant. Currently, its existence in the wild increasingly threatened. Pengelengan Hill is one of the natural habitats of E. horsfieldii in Bali. Study of autecology aims to describe the ecology of E. horsfieldii in their natural habitat. E. horsfieldii was found abundant in plots II with 16.02% relative density, 9.68% of relative frequency and 25.69 of Important Value, grow clumped together with other plants (Idk 2.72).

Abstract

Dicksonia blumei (Paku Kidang) termasuk dalam spesies prioritas konservasi Indonesia kategori B. Studi ekologi habitat alaminya di kawasan hutan Bukit Tapak, Bedugul Bali dilakukan dengan metode purposive sampling. Plot dapat dibuat sebanyak 3 (tiga) buah dengan ukuran 20 x 20 m untuk jenis tumbuhan pohon dan 2 x 2 m untuk jenis tumbuhan bawah. Berdasarkan hasil pengamatan Dicksonia blumei (Paku Kidang) pada habitat alaminya di kawasan hutan Bukit Tapak. Jenis paku ini tumbuh pada kondisi lingkungan fisik dengan kisaran ketinggian tempat antara 1.754–1.794 m dpl., kemiringan tanah berkisar antara 7–10%, pH tanah 6,4–7, kelembaban tanah 50–75%, temperatur 20,5–22,3°C, kelembaban udara 83,2–87,5% dan intensitas cahaya 618–10.030 Lux. Karakteristik komponen lingkungan biotiknya ditentukan berdasar Indek Nilai Penting (INP). Lima jenis tumbuhan pohon dengan INP tertinggi adalah Cyathea latebrosa (INP 98,7) kemudian diikuti oleh Saurauia bracteosa (INP 51,9), Astronia spectabilis (INP 42,7), Dicksonia blumei (INP 39,6) dan Homalantus giganteus (INP 35,3). Karakteristik jenis tumbuhan bawah untuk lima jenis tertinggi diduduki oleh Pillea sp. (INP 61,91), kemudian diikuti oleh Selaginella sp. (INP 40,6), Athyrium asperum (INP 27,5), Pteris tripartita (INP 18,3) dan Rubus sp. (INP 15,0). Kebersamaan tumbuhnya D. blumei dengan Cyathea latebrosa, tampaknya terkait dengan peran batangnya sebagai substrat spora D. blumei pada tahap perkecambahan dan pertumbuhan selanjutnya. Pada fase gametofit dan sporofit muda D. blumei tumbuh secara epifit pada batang Cyathea latebrosa setinggi 0,5–1,5 m dari permukaan tanah. Seiring dengan pertumbuhan akarnya yang berlahan-lahan mencari tanah, kemudian sporofit dewasa D. blumei akan tumbuh secara teresterial (hemi–epifit).

Abstract

Balinese Hindu community cannot be separated from plant in their life. The information on plant species and how to utilize them are easy to find but limited information about the potency of flowers in the Balinese Hindu community. Flowers have a meaning as sincerity, a symbol of Sang Hyang Widhi, the valour, and also have mythological values. This research aimed to determine the species of flowering plants that are often used for ceremonial and understand the meaning, the cultural conception related to conservation education. The study was carried out in four locations in Tabanan Regency (Baturiti, Penebel, Marga, and Tabanan). Data were collected using an interview with purposive sampling. Data analysis based on the value of Relative Frequency (FR) which is indicated plant most widely used.  A total of 36 species of flowers are used in traditional Hindu religious ceremonies, of which 29 species are cultivated plants and 7 species are still wild. There are ten of plants which have high FR value, such as: Cananga odorata (FR 0.069), Impatiens balsamina (FR 0.069), Hydrangea macrophylla (FR 0.069), Plumeria acuminata (FR 0.069), Tagetes erecta (FR 0.069), Magnolia champaca (FR 0.069), Gomphrena globosa / bunga ratna (FR 0.047), Gardenia jasminoides / jempiring (FR 0.039), Nymphaea spp./ tunjung (FR 0.030), and Hibiscus rosa-sinensis L./ pucuk (FR 0.030). This research revealed the role of flower in Hindu ceremony and describe the strategic plant conservation due to culture of Balinese Hindu community. Finally, this research expected to documented local knowledge about flowers used as Hindu religious ceremonies, to provide an understanding of the meaning and conceptions of culture related to conservation education.
