Abstract

The physical and chemical environmental impact in a mining area is inevitable, particularly for open pit mining areas. The impact could affect soil and water quality where mining activities, such as land clearing, blasting and hauling, occur. Thus, environmental monitoring in mining areas should be taken to measure the impact of mining activity for reclamation purposes. The objective of this research focuses on the measure of environmental impact on soil quality in terms of the nutrient content in an abandoned mine area at Jantang village, Lhoong, Aceh Besar. The research was conducted by collecting 15 soil samples, followed by laboratory analysis using atomic absorption spectrophotometry to investigate sampled 'soil's nutrients which are pH, Carbon (C-organic), Nitrogen (N-total), Phosphor (P-availability), and Ferro substance (Fe-concentration). In addition, to estimate the soil properties at locations outside the sampling area, a spatial interpolation method called inverse distance weight with an optimum power was used. The result shows that the soil is acidic, with low C-organic in the range of 0.02%1.84%, N-total 0.02%0.16%, and P-availability 0.55%3.75%. In contrast, the Fe-concentration is very high, at 30003400 ppm.

Abstract

The large amount of liquid waste generated from urban activities can provide negative impacts, such as disease spread, environmental damage, and others. Therefore, treatment efforts before disposal into the environmental are crucial. One method of treating liquid waste that can be used is the trickling filter. The trickling filter method used in this research utilizes natural fibers, namely coconut fiber, as the packing media, replacing sand or plastic as the packing media in conventional trickling filters. Treatment of municipal liquid waste (domestic waste) using coconut fiber trickling filters is one application of biofilm technology in wastewater treatment, where a biological layer (biofilm) like mucus will grow on the surface of the media. This biological layer will meet the wastewater and degrade the pollutant compounds presentin the wastewater, resulting in water with lower biological oxygen demand (BOD) values than before. Theresult if water that is safe for disposal into the environment. This trickling filter reactor can degrade pollutants with degradation efficiency of BOD 91.3%, nitrate 50.25%, and ammonia 37.5% at the optimal flow rate of this study (0.256 L/min).
