Abstract

Analysis of the influence of vegetation density levels on the concentration of Total Suspended Solids (TSS) in aquatic areas is crucial in the Pomalaa District, an area characterized by extensive mining activities. This research aims to examine changes in vegetation density conditions and analyze the influence of vegetation density levels on TSS concentrations in the aquatic region. Changes in vegetation density conditions are analyzed through multi-temporal remote sensing image processing using the NDVI method. The TSS concentration is analyzed using the gravimetric method. Meanwhile, the influence of vegetation density level on TSS concentration is analyzed using the Pearson correlation coefficient equation. The results of the research show that there has been an increase in the area with very low levels of vegetation density and a decrease in the area with high levels of vegetation density in the period 2014 to 2023. The calculated results of TSS concentrations at the research location are 78 mg/l to 111 mg/l. The correlation analysis shows that the broader the area with very low vegetation density, the higher the TSS concentration in the aquatic environment. Additionally, the larger the area with high vegetation density, the lower the TSS concentration value of the water at the research locations.

Abstract

Waste pollution pollutes land and water, causing the content of several chemicals to be at the threshold of safety standards and will have a negative impact on living things. One of the compounds often found in pollution cases is Nitrogen in the form of Organic Nitrogen and Inorganic Nitrogen which play a role in the Nitrogen (N) cycle. Research was carried out to determine the content of these three compounds using the Kjedahl distillation method using refill drinking water samples taken from the DAMIU. Kjedahl distillation will produce a Kjedahl Total Nitrogen (TNK) value which must be explained through further treatment, namely measurement using a Uv-Vis Spectrophotometer. The results showed NO2 values ​​of 0.603 mg/l (pre-distillation) and 0.443 mg/l (post-distillation) with a maximum limit of 20 mg/l, NO3 values ​​< 0.0005 mg/l (pre-distillation) and 0.026 mg/l (post-distillation) with a maximum limit of 3 mg/l and NH3 values ​​of 0.045 mg/l (pre-distillation) and 0.096 mg/l (post-distillation) with a maximum limit of 1.5 mg/l. Other supporting parameters tested to determine drinking water quality include physical parameters, chemical parameters and microbiological parameters. The conclusion that can be drawn is that the production of drinking distilled water using the Kjedahl method will produce distilled water that is free of minerals and of good quality. Apart from that, distilled drinking water also has many health benefits, including reducing the risk of disease and reducing the risk of exposure to dangerous chemicals because this water is pure, free of minerals and metals..
