Abstract

Utilization of rhizosphere microbes such as arbuscular mycorrhizal fungi (AMF) and mercury-resistant bacteria (MRB) is one of the alternative technologies that can be used synergisti-cally to overcome the main problem in biologically rehabilitation of marginal and mercury (Hg) contaminated tailings in ex gold mining area. The research was aimed to get an effective combination of AMF isolates (Glomus sp. SS11, Glomus sp.SS15, Glomus sp.SS18) with MRB isolates (Bacillus sp. HgTA1 and Pseudomonas HgRA) in supporting seedlings growth of sengon laut (Paraserianthes falcataria (L.) Nielsen) and sengon buto (Enterolo-bium cyclocarpum Griseb) in mercury-contaminated tailings. Dual inoculation of Glomus sp. SS15 with Bacillus sp. HgTA1 or Pseudomonas sp. HgRA isolates; dual inoculation of Glomus sp. SS18 with Bacillus sp. HgTA1 or Pseudomonas sp. HgRA isolates; single inoculation or dual inoculation of Glomus sp. SS11 with Pseudomonas sp. HgRA isolates were proven to be very effective in increasing P. falcataria seedlings height. However, only single inoculation of Bacillus sp. HgTA1 isolate was effective in increasing E. cyclocarpum seedlings height. Hg accumulation in plant tissue of P. falcataria and E. cyclocarpum, either with or without rhizosphere microbial inoculation, indicated that both plants were highly potential as Hg phytoextraction or phytostabilization agents.  Key words: arbuscular mycorrhizal fungi, Enterolobium cyclocarpum Griseb, mercury, mercury-resistantbacteria, Paraserianthes falcataria (L.)

Abstract

This study aims to obtain information about the succession levels of natural vegetation on ex – community gold mining in Monterado. The method of this research was survey method through vegetation analysis by double plot size 20 m x 20 m. Placement of plots dileberately based on the tailing period of ex – community gold mining which were : < 1 year, 2-3 years, 5-7 years, and > 10 years. The result showed that kinds of shrub found in all age level of ex – community gold mining area. The type of woody plants at the seedling found in all period of ex – community gold mining area, whereas sapling, pole and tree only found in ex – community gold mining at age level > 10 years. Based on the vegetation analysis, it showed that Ischaemum rugosum and Melastoma malabathricum L. dominanted at all age level of ex – community gold mining. Seedling in the ex – community gold mining at all age level were dominanted by Dillenia suffruticus. The index of species diversity showed that it was still low on ex – community gold mining in Monterado.Until the age of tailing > 10 years, succession was still in the level of competition, so it was concluded to be slow. To accelerate succession, revegetation, land restoration, and people awareness should be undertaken.Keyword : Gold mining, Monterado Sub district, Succession.

Abstract

Pulai (Alstonia scholaris) is a fast growing local species that can be used rehabilitation activities on peat swamp forest. This study aims to obtain information application the response of growth and quality of pulai seedlings to wood vinegar and shade. The research was carried out at orchid exsitu observation site stock  and community service and in the silvicultural laboratory of Faculty of Forestry. This study applied an experimental method with a split plot design with a complete randomized design (CRD). The treatment consisted of two factors,“shading” as the main factor and kind of  organic vinegar as  sub  factor. The results obtained were based on observations 12 weeks after planting, the growth percentage of pulai seedlings for the 100%, while ofthen variables in this study had no effect. The main factor is organic fertilizer with 2 levels: chemical fertilizer and wood vinegar, while the shade factor is a main factor that less interest. Results showed that the response of height growth was significantly higher 13.0% to chemical fertilizer than wood vinegar when planted in a shadeless condition. However, if planted in conditions with a shade of 60%, the response was no different. The response of leaves growth to fertilizer is significant when planted under different shade conditions. In the condition without shade, the response of leaves is 11.8% higher compared to wood vinegar. Conversely, in condition with shading 60%, the response  the number of leaves growth on wood vinegar was 13.0% higher than that of chemical fertilizer. In this study, the concentration of wood vinegar as much as 4% was not effective enough to increase the enhance  of pulai seedlings.Keywoards: Organic vinegar, pulai seedlings, shade

Abstract

Phosphate in the soil is a nutrient that plays an important role in the process of plant growth. In nature, the availability of phosphate is aided by phosphate solubilizing bacteria (PSB) which are common in the rhizosphere. The purpose of this study is to obtain the information on density of PSB population density isolated from former burnt peatlands in Kuala Dua village with different depth and distance from the trench edges. Peat soil sampling was taken by using systematic sampling method and bacterial isolation was carried out on Pikovhskaya media using pour plate method, while the calculation of bacterial density was counted by plate method. The results showed that the lowest BPF colony population density on burnt peat soil was 9.17 x 104 CFU/g soil (isolated from peat depth of 20-50 cm) and the highest colony density of PSB was 141,000 x 104 CFU/g of soil (isolated from peat depth of 0-20 cm). The existence of PSB on burnt peatlands is a biological potential that could be developed to support the efforts of restoring the degraded peatlands.Keywords: burnt peatlands, phosphate solubilizing bacteria, restoration
