Abstract

Penelitian ini untuk mengetahui jenis-jenis anggrek apa saja yang dapat ditemukan di hutan Mandahan dan mendriskripsikan tingkat Keanekaragaman jenis anggrek familia orchidaceae di hutan Mandahan Tumbang manjul Kecamatan Seruyan Hulu Kabupaten Seruyan.

Jenis penelitian ini adalah deskriptif eksploratif. Pengumpulan data dilakukan dengan observasi langsung di hutan Tumbang Manjul menggunakan metode pengambilan sampel dengan teknik Accidental Sampling yaitu menentukan tempat-tempat dimana ditemukan sampel semua jenis tumbuhan anggrek sedangkan penentuan wilayah menggunakan porpusive sampling yang terdapat di area hutan Mandahan Tumbang Manjul Kecamatan Seruyan Hulu kabupaten Seruyan. Pengambilan wilayah sampel terbagi menjadi dua yaitu hutan terbuka dan hutan semi tertutup.

Hasil penelitian ditemukan jenis anggrek di hutan terbuka 4 jenis,yaitu Dendrobium crumenatum Sw, Schoenorchis juncifolia, Dipodium paludosum dan Spathoglottis plicata Blume. Sedangkan di hutan semi tertutup ditemukan 13 jenis anggrek, yaitu Acriopsis javanica Reinw, Dendrobium crumenatum Sw, Bulbophyllum purpurascens, Bulbophyllum lepidum, Bulbophyllum lobii, Dendrobium aloifolium, Dipodium paludosum, Cymbidium finlaysonianum, Appendicula hexandra, Coelogyne pandurata, Coelogyne speciosa (Blume) Lindl, Coelogyne speciosa incarnata, dan Pematocalpa latifolia. Jenis anggrek yang ditemukan di dua tempat, hutan terbuka dan hutan semi tertutup berjumlah 2 jenis, yaitu Dendrobium crumenatum Sw dan Dipodium paludosum. Hasil perhitungan analisis indeks keanekaragaman jenis anggrek famila orchidacea di daerah kawasan hutan terbuka dan hutan semi tertutup menunjukan kategori sedang. Selanjutnya tidak terdapat perbedaan yang signifikan antara keanekaragaman jenis anggrek pada kawasan hutan terbuka maupun kawasan hutan semi tertutup dengan nilai indeks indeks keanekaragaman berturut-turut adalah 1,331 dan 2,499 dengan tingkat keaneragaman sedang.

ABSTRACT

The objective of this study is to find out what species of orchid can be found in Mandahan forest and to describe orchid species level diversity of Orchidaceae family in Mandahan Tumbang Manjul forest Seruyan Hulu Subdistrict Seruyan Regency.
This study used descriptive explorative. Data collection techniques were through direct observation in Tumbang Manjul forest and accidental sampling method which by determining the places where samples of all orchid species, while the determination purposive sampling were found in forest area of Mandahan Tumbang Manjul Seruyan Hulu Subdistrict Seruyan Regency. Area sampling was divided into two: opened forest and semi-enclosed forest.
The results showed that there were 4 species of orchid in opened forest, namely Dendrobium crumenatum sw, Schoenorchis juncifolia, Dipodium paludosum, and Spathoglottis plicata blume. Meanwhile, there were 13 species of orchid in semi-enclosed forest, such as Acriopsis javanica Reinw, Dendrobium crumenatum Sw, Bulbophyllum purpurascens, Bulbophyllum lepidum, Bulbophyllum lobii, Dendrobium aloifolium, Dipodium paludosum, Cymbidium finlaysonianum, Appendicula hexandra, Coelogyne pandurata, Coelogyne speciosa (Blume) Lindl, Coelogyne speciosa incarnata, and Pematocalpa latifolia. Further, there were 2 species of orchid that found in both opened and semi-enclosed forest: Dendrobium crumenatum Sw and Dipodium paludosum. The calculation result of index analysis of orchid species diversity of orchidaceae in opened forest and semi-enclosed forest showed medium category. Furthermore, there was no significant between orchid species diversity in opened forest and semi-enclosed forest area with index value were 1,331 and 2,499 on medium level.
