Abstract

Enrichment planting in logged-over area needs high-quality seedlings that have high competitiveness, when planted around or near to other plants that grow naturally. The aim of this study is to find techniques to produce high-quality ramin seedlings. The studie employr the following experimental methods : 1) split plot in time to study the arbuscular mycorrhizal fungi (AMF) colonization in roots of natural regeneration of ramin, 2) completely randomized design to study the growth of ramin seedlings in the nursery, 3) randomized block design to study plant growth of ramin at logged-over area. The results show that AMF colonization in the root of ramin seedlings taken from the field was highest at medium light intensity. Meanwhile, the optimum light intensity to raise mycorrhizal seedlings in the nursery is 55 % to 75 %. The AMF colonization increased height and diameter growth, fresh and dry weights, macro-nutrients absorption, dependency of P uptake (DPU), shoot-root ratio quality and index of ramin seedling in the nursery. Ramin is highly dependent on AMF having a relative mycorrhizal dependency (RMD) of more than 50 % and percent growth relative (PGR) of more than 100 %. Rock phosphate of 50 g/polybag is sufficient to support the growth of mycorrhizal seedlings in the nursery. The AMF colonization increases height and diameter of ramin seedlings after being planted in the field (logged-over area). It could be concluded that high quality ramin seedlings could be produced by inoculation of AMF under optimum light intensity and optimum dosage of rock phosphate.Key words : ramin (G. bancanus), light intensity, arbuscular mychorrhizal fungi (AMF), rock phosphate

Abstract

Gunung Palung National Park had lost 35% of its primary forests over the past 30 years. A forest restoration program is thus vital to restore the damaged forest ecosystems. This study aims to analyze the presence of orangutan food supply and Shannon-Wiener index at Alam Sehat Lestari (ASRI) restoration site in Gunung Palung National Park. The method applies a species data collection of orangutan food (in 91 sample plots) and calculation of Shannon-Wiener index (in six 2009's plots). The result depicted approximately 65 species from 25 families found in ASRI restoration site. Eighty percent of those species indicated orangutan food.  In addition, the restoration site is believed to prevent the orangutan conflict with a human due to food availability in restoration areas for orangutans. Analysis of the Shannon-Wiener index (H') demonstrated a value of H' = 2.789, which indicated that the reforestation forest was in stable condition. The effect of increasing biodiversity as characterized by orangutan nests at restoration sites escalates the presence of wildlife.Keywords: Forest Restoration, Gunung Palung National Park, OrangutanTaman Nasional (TN) Gunung Palung telah kehilangan 35% hutan primer selama 30 tahun terakhir.

Abstract

Ex-mining land use of cement was an alternative medium or planting medium, but this alternative was to meet the constraints of low soil fertility levels. Therefore, one way that could be attempted is creating suppressive soil in the form of applying biofertilizer such as rhizobium (Nitrogen Fixing Bakteria). Research methods used a complete randomized design. The first factor was the type of Rhizobium (control, Shinorhizobium sp (S8.4), Rhizobium sp (S10.3.1) which was inoculated on the plant Paraserianthes falcataria. Planting medium used was sterilized soil from ex-cement mining land. The results of rhizobium inoculation on plants showed different effectiveness in enhancing the growth of seedlings. Duncan test results of the influence of a single factor BFN showed Shinorhizobium sp (S8.4) could be associated with P. falcataria, to improved seedling growth and able to gave growth response better when compared with treatment of Rhizobium sp (S10.3.1) and control at variable observations on seedling diameters (1.65 mm), number of leaves (10.9 pieces), N absorption (2.10 g/plant) and P absorption (0.16 g/plant). Keywords: Paraserianthes falcataria, rhizobium, bacteria, seedlings, soil media of ex - cement mining
