Abstract

This study was conducted to collect information regarding carbon storage, particularly the carbon stored in the aboveground biomass as well as in the peat soil. The study site was in a conservation area of the PT National Sago Prima belonging to the PT Sampoerna Agro Tbk. Group. The work was undertaken in January-February 2012. The total aboveground biomass and carbon storage in the research site indicates  that the conservation area is a secondary peat swamp forest, with the biomass of 149.18 ton/ha and carbon stock of 70.12 ton C/ha. The aboveground biomass and carbon consisted of biomass and carbon of tree (83.97 ton/ha containing 39.47 ton C/ha, respectively), saplings (20.69 ton/ha containing 9.72 ton C/ha) and seedlings and undergrowth plants (0.03 ton/ha containing 0.01 ton C/ha), wood  necromass (24.06 ton/ha containing 11.31 ton C/ha), and litter (20.44 ton/ha containing 9.61 ton C/ha). An allometric equation was developed for Pandanus atrocarpus Griff. providing an estimated total biomass and carbon of 5.16 ton/ha containing 2.42 ton C/ha. The underground C with the mean peat depth of 5.5 m, mean bulk density of  0.18 g/cm3, and the mean organic C of 46.6 % was 464.895,94 ton C/ha. In the entire conservation forest area of 541 ha the total aboveground biomassa and carbon storage was estimated to be  80,708.64 ton and 37,934.00 ton C, while the total underground carbon was 238,96 million MT C.

Abstract

We studied the floristic composition and structure of the logged-over peat swamp forest in the  PT National Sago Prima of PT Sampoerna Agro Tbk. group for future management of the conservation area that has been  set aside by the company.  In January - February 2012, 25 quadrats of 20 m x 20 m were laid out systematically along a transect,  thus covering a sampled area of 1-ha.  The results showed that the study site was a regenerating and developing secondary peat swamp forests having high plant species richness.  The total number of species recorded was 73 species of 38 families, consisting of 49 species (30 families) of trees (DBH? 10 cm ), 42 species (24 families) of saplings (H > 1.5 m and DBH < 10 cm), and 41 species (27 families) of seedlings and undergrowth.  Tree density was 550 individuals/ha, and total tree basal area was 18.32 m2. The Shannon-Wiener’s Diversity Index for trees was high  (3.05)  Two tree species with the highest Importance Values (IV) were Pandanus atrocarpus (IV= 45.86 %) and Blumeodendron subrotundifolium (22.46  %).  The tree families with the highest IV were Pandanaceae (45.86), Myrtaceae (40.37), and Dipterocarpaceae (39.20). Forest structure dominated by trees with a diameter below 20 cm amounting to 408 trees/ha (74.05%). and  D and E strata with height of less than 20 m, and density of 431 trees/ha (78.36%). Jaccard Similarity index among species, showed  strong association between Pandanus atrocarpus and Blumeodendron subrotundifolium  and based on this association combined  with high IVs, the two parameters of species  characterized the forest, hence the forest could be designated as the Pandanus atrocarpus--Blumeodendron subrotundifolium association. Primary forest species with high economic values were still present in the forest. Eleven species can be included in the IUCN Red List, of which Shorea rugosa is in the category of Critically Endangered), Shorea tesymanniana Endangered and  Gonystylus bancanus vulnerable, hence they should  be protected.

Abstract

RAHMAH, KARTAWINATA, K., NISYAWATI, WARDHANA, W. & NURDIN, E. 2016. Tree species diversity in the lowland forest of the core zone of the Bukit Duabelas National Park, Jambi, Indonesia. Reinwardtia 15(1): 11 - 26. — An analysis of the composition and structure of a one-hectare plot of forest on a lowland hill slope in the eastern core zone of the Bukit Duabelas National Park, Jambi, was conducted in October and November 2012. The objective of the study was to obtain a descriptive account of the structure and tree species composition of a lowland forest in the eastern core zone of the park. The plot was divided into 100 subplots of  (10 m × 10 m) each and the seedling subplots (5 m × 5 m) were nested in the sapling subplots. A total of 414 trees were recorded with DBH (Diameter at Breast Height) ?10 cm, representing 113 species and 38 families, with the total BA (Basal Area)  of 25.71 m2 and Shannon- Wiener diversity index of 4.29. Prunus arborea with IV (Importance Value) of 19.19 is the dominant species and the other prevalent species were, Dracontomelon dao (IV =11.46) and Hydnocarpus sp. (IV =11.38). A total of 44 species (38.9%) had each density of 1 tree/ha, which may be considered locally rare. Ficus fistulosa had the highest density (24 trees/ha) and Prunus arborea had the highest BA (3.28 m2 = 12.8% of the total). Only 10 species had F (frequency) of 8-18%, of which Hydnocarpus sp. had the highest (18%); the remaining species had F<8%, which may be considered locally rare. Moraceae (IV= 34.05) was the dominant family. The two richest families were Moraceae (11) and Clusiaceae (9). A total of 61 species were registered in the Sumatra checklist and one of them was endemic (Baccaurea dulcis). A total of 13 species are listed in the IUCN Red List. The forest is a developing community after disturbance in the past with poor regeneration. Species with complete representation of trees, saplings and seedlings will probably remain in the forest in the future.

Abstract

Sumatra has rich diversity of orchids. The local communities in Sumatra have been used orchids as a ornamental plant, food, and medicine. Research on utilitation of orchids as medicinal plants by ethnic Batak of North Sumatra was conducted using ethnobotanical methods. The objectives of the research was to know species of orchids that were used as medicinal plants by Batak ethnic in North Sumatra. Respond-ents consisted of traditional medicine plants traders in the traditional markets and traditional healers. We found as many as seven species of 6 genera of orchids have been used as traditional medicine. Those orchids used as medicine for fever, aphrodisiac, maintain stamina, respira-tory disorders, and gastrointestinal disorders.

Abstract

Masyarakat Lereng Gunung Slamet memiliki pengetahuan diversifikasi satuan lanskap yang didasarkan atas fungsi, karakteristik, dan kepemilikan. Tujuan penelitian ini adalah untuk mempelajari struktur komunitas satuan lanskap yang dimanfaatkan oleh Masyarakat Lereng Gunung Slamet. Penelitian dilakukan pada bulan Juli 2019 — Januari 2020 di desa Lereng Gunung Slamet yaitu, (1) Desa Ragatunjung, (2) Desa Cipetung, dan (3) Desa Pandansari Kecamatan Paguyangan, Kabupaten Brebes. Pengumpulan data botani dilakukan dilakukan secara purposive sampling menggunakan transek kuadrat. Analisis vegetasi diolah menggunakan Indeks Nilai Penting (INP), Indeks Keanekaragaman (H’), Indeks Kekayaan (DMg), Indeks Kemerataan (e’), dan Indeks Kesamaan komunitas. Berdasarkan Analisis vegetasi ditemukan 136 spesies yang dikategorikan ke dalam 11 genus dan 55 famili. Analisis struktur komunitas dapat dilihat pada H’ berkisar antara 1,57—28,9 yang termasuk dalam kategori sedang. DMg berkisar antara 11,82 – 28,8 dan Indeks kemerataan berkisar antara 0,11—0,92. Indeks kesamaan antar satuan lanskap,  wanah dan majegan merupakan yang tertinggi yakni 62,67% yang termasuk kategori tinggi. Selanjutnya nilai Indeks kesamaan jenis lanskap yang sama antar desa, tertinggi pada lanskap majegan di Desa Cipetung dan Pandansari (45,71%.) dan wanah pada Desa Ragatunjung dan Desa Cipetung (42,86 %).
