PEMANFAATAN Typha angustifolia DAN FUNGI MIKORIZA ARBUSKULAR UNTUK FITOREMEDIASI AIR ASAM TAMBANG

Abstract

Acid mine drainage is water originating from mines or rocks containing sulfide minerals which are exposed and oxidized as a result of open-pit mining activities. The high content of sulfates and metals in acid mine drainage causes environmental damage, so special handling is required. Phytoremediation can be used to overcome these problems so that it is in accordance with the environmental quality standards for acid mine drainage. The purpose of this study was to determine the effect of the application dose of arbuscular mycorrhizal fungi (AMF) on the growth and metal uptake of Typha angustifolia accumulator plants in acid mine drainage. This study used a completely randomized design with 4 treatments, namely m0 (0 g AMF/bucket), m1 (10 g AMF/bucket), m2 (12 g AMF/bucket), m3 (14 g AMF/bucket) and 4 replications, so that obtained 16 experimental units. The plant height, number of tillers, root-Fe, root-Mn, soluble-Fe, soluble- Mn, AAT pH and the relationship between variables were observed. The best dose to increase the growth of T. angustifolia was m3 treatment (14 g AMF/bucket), whereas for Fe and Mn absorption was m2 treatment (12 g AMF/bucket) with index fitoremediation (IFR) Mn and Fe of 98.94% and 57.93% have met environmental quality standards.
