Application of Ectomycorrhiza (Scleroderma sp.) in Mangium (Acacia Mangium Willd.) using Artisanal Small-scale Gold Mining(ASGM) Tailings
Jurnal Sylva Lestari
Artisanal small-scale gold mining tailings frequently used hazardous toxic materials that could contaminate land, rivers, and lakes which harmful to the environment and health. Phytoremediation is one way to overcome the mining waste. Mangium (Acacia mangium Willd.) is one of plant that often used for mining land phytoremediation. However, it was difficult for mangium to be able to survive on land with such extreme conditions, therefore additional input is needed. Using ectomycorrhiza fungi
... ycorrhiza fungi could be an alternative. This study aimed to measure the adaptation of mangium in gold mining tailings and analyze the function of ectomycorrhiza (Scleroderma sp.) in the growth of mangium. The experimental design used a completely randomized design with six growth media as treatments with five replications. The growth media used were: (1) topsoil with mycorrhiza, (2) topsoil without mycorrhiza, (3) topsoil + tailings with mycorrhiza, (4) soil + tailings without mycorrhiza,(5) tailings with mycorrhiza, and (6) tailings without mycorrhiza. Data were analyzed statistically using analysis of variance followed with a Least Significant Difference test. The results showed that the survival rate of mangium life in tailing media with mycorrhizae was fairly high with a percentage of life reaching 60% even though the growth was less when compared to topsoil media with mycorrhiza that reached 100%. The highest growth rate was achieved by mangium in topsoil media without tailings and mycorrhiza (control). This research showed that ectomycorrhiza did not have any significant effects on mangium growth in gold tailing.Keywords: Acacia mangium, ectomycoriza, gold tailings, phytoremediation, Scleroderma sp.
