Abstract

Mining activities have a positive impact that can generate income for the state, but the activities also cause negative impacts in the form of soil damage, vegetation and animal losses to disrupt the ecosystems. Therefore, it is necessary to carry out a reclamation with revegetation using local plant species. PT Berau Coal has conducted revegetation using a local sugar palm plant (Arenga pinnata). The success of sugar palm plant growth in post-mining reclamation land is influenced by several factors, one of it is the symbiosis of the arbuscula mycorrhizal fungi (AMF) with the sugar palm planted by PT Berau Coal. The purpose of this study was to determine the diversity of indigenous spores in the arenga rhizosphere and root colonization of sugar palm plants. Identification of the AMF diversity was carried out by observing the soil taken from the palm rhizosphere with a depth of 0-20 cm and 20-40 cm. Isolation of spores using the wet pouring technique method with centrifuges and AMF spores were identified using the INVAM methods. The observation of AMF colonization on plant roots was carried out through the root staining technique with the Clapp modification method. The results showed that the AMF spores were found in 3 AMF genera at the observation site, namely genus Glomus (15 sp), Acaulospora (3 sp), and Gigaspora (1 sp). The highest spore abundance is genus Glomus sp at a soil depth of 0-20 cm. The AMF structures found colonizing the roots of sugar palm plants are hyphae, vesicles, and spores.

Abstract

Acid mine drainage (AMD) is one of the most serious environmental impacts of mining, characterized by low pH and high metal content. This study aimed to evaluate the neutralization efficiency of waste-based granules made from fly ash, bottom ash (FABA), and goat manure for AMD treatment under laboratory conditions. Two types of granules were produced: (i) 45% fly ash, 45% bottom ash, and 10% cement; and (ii) 45% fly ash, 30% bottom ash, 15% goat manure, and 10% cement. Each type was applied at different volumes (10%, 30%, and 50%) and positions (bottom and suspended) for 48 hours. Results showed that granule type, volume, and placement significantly influenced pH neutralization and metal removal. The best performance was achieved by the suspended granule without manure at 50%, raising AMD pH from 2.45 to 9.17 within 3 hours, with 88.7% Fe and 66.5% Mn removal. XRD and Micro-XRF analyses confirmed that neutralization occurred through dissolution of Ca-based minerals and formation of calcite and gypsum. The study demonstrates that FABA granules offer a low-cost, sustainable option for AMD treatment and can serve as a contextual learning model in environmental and chemistry education, linking waste utilization with real-world applications of acid-base reactions and environmental sustainability.
