Abstract

Aquilaria spp. merupakan kelompok tumbuhan penghasil aromatik bernilai komersil tinggi melalui produk gubal gaharu dan kamedangan. Budidaya tanaman gaharu merupakan salah satu langkah nyata di dalammenjalankan program pemanfaatan dari alam secara berkelanjutan. Untuk itu dilakukan penelitian mengenai usaha budidaya pohon penghasil gaharu di Provinsi Bengkulu. Penelitian dilakukan dalam bentuk rapidassessment pada bulan April 2008 dengan mengunjungi beberapa lokasi penanaman pohon gaharu (Aquilaria spp.) yang ada di Kabupaten dan Kota  Bengkulu.  Pada setiap kunjungan ke lokasi budidaya dilakukan wawancara terstruktur mengenai sejarah penanaman serta dilakukan pengukuran diameter setinggi dada (dbh) dan tinggi pohon-pohon gaharu. Kamedangan segar hasil tebangan dan gubal gaharu hasil inokulasidiukur berat dan kandungan airnya. Hasil penelitian menunjukkan bahwa penanaman pohon penghasil gaharu di tingkat masyarakat diprakarsai oleh perusahaan lokal. Sampai dengan Juli 2008 jumlah petani gaharubinaan mencapai 29 jiwa dengan luas penanaman 38,0 ha serta jumlah penanaman mencapai 5.000 pohon, sedangkan kegiatan inokulasi pada tumbuhan gaharu alam mencapai  53 ha. Pemahaman konsep budidayasesuai perundangan masih harus disosialisasikan mengingat adanya perbedaan persepsi, khususnya pada status pohon penghasil gaharu alam yang diinokulasi dengan sengaja. Jenis pohon penghasil gaharu yangdibudidaya dan tumbuh alami di perkebunan masyarakat adalah Aquilaria microcarpa Baill. dan A. malaccensis Lam. Berat gubal gaharu hasil inokulasi kondisi siap jual rata-rata 18,79 gram/potong (standardeviasi 8,85) dengan kandungan air 11,2-12,97%. Kandungan air pada kamedangan hasil tebangan baru adalah 46,3%. Satu pohon penghasil gaharu dengan tinggi 35 m dan dbh 118 cm setidaknya menghasilkan637,65 kg kamedangan kering siap jual

Abstract

In the S. E. Asiatic genus Spatholobus 28 species are recognized, 6 of which are never described before: S. albus S. auricomus, S. auritus, S. hirsutus, S. multiflorus and S. viridis. One variety (S. ferrugineus var. acutus) is also newly described. A key and full descriptions with plates and maps to illustrate the distribution are given.

Abstract

Two new species of Begonia, Begonia holosericeoides Ardi & D. C. Thomas and B. aketajawensis Ardi & D. C. Thomas, are described from Aketajawe Lolobata National Park, Halmahera, Indonesia. The two species belong to Begonia section Petermannia. Begonia  holosericea, previously only tentatively assigned to a section, is here assigned to section Petermannia based on the examination of newly available material. Additionally, a revised description and an illustration are provided. A key to the Moluccan species of Begonia is presented.

Abstract

One hundred forty-five individual lianas were distributed on 2 East facing ridges on the second highest mountain on Java, Mt. Slamet (3418 m.), Central Java, Indonesia. Twenty one colonies were observed on small flat areas on ridges. The liana species observed include: Embelia pergamacea, Toddalia asiatica, Elaeagnus latifolia, Schefflera lucida, Vaccinium laurifolium and Lonicera javanica. Diameter of each liana was measured and liana density/flat area calculated. Floristic collecting was under- taken within the elevational gradient of liana distribution. Data suggest an ecotone transition from lower to upper mon- tane forest is observed between 2200 and 2300 m, though forest types are difficult to determine due to disturbance caused by fire at the upper elevations. Observing lianas at these unusuall high elevations with near pluvial rainfall, con- tradict established scientific theory concerning global distribution and abundance of lianas.
