Abstract

An appeal has been tested for two methods of Wet Digester destruction with Muffle Furnace for determination of Pb (lead) metal ion content in hair. The Wet Digester destruction uses temperature 578oC for 4 hours and the addition of HNO3(p) at the beginning and end of destruction, while Muffle Furnace destruction uses temperature 600oC and addition of HNO3(p) at the end of destruction.Analysis of Pb (lead) metal ion content of destruction results was done with Atomic Absorption Spectrophotometer (AAS).Results of laboratory analysis that in the workers hair of heavy equipment Department Bintang PT. KPC is shown to contain Pb (lead) metal ions. To determine a more valid method of extraction performed linear regression testing, correlation coefficient, Ttabel test and determinant coefficient. The results of linear regression testing for the destruction of Wet Digester obtained r value = 0,867, the correlation coefficient r = 0,867 ≥ r table = 0,564 (positive correlation) and the coefficient of determinant % D = 75,2 %, while the results of linear regression testing for Muffle Furnace destruction obtained r value = 0,864, correlation coefficient r = 0,849 ≥ r table = 0,564 (positive correlation) and the coefficient of determinant % D = 74,8 %. The Destruksi Wet Digester is more valid than the Muffle Furnace destruction because the linear regretting value is closer to the value of r = 1 (perfect linear regression value) and the correlation coefficient and the determinant coefficient of Wet Digester destruction is higher than the correlation coefficient and the determinant coefficient of Muffle Furnace destruction . Keywords: Hair, Lead, Correlation Coefficient, Determination, Wet Digester, Muffle Furnace, Absorption Spectrophotometer (AAS)

Abstract

The use of settling pond dimensions in coal mining has been widely used to reduce chemical-physical pollution of wastewater. This study aims to take advantage of the dimensions of the settling pond in wastewater pollutants based on quality and to see the comparison of the actual load of wastewater with the maximum pollutant load in the settling pond location. The method in this research is descriptive qualitative. The sampling location consisted of 3 stations, namely the settling pond location 1, location 2 and location 3. The results showed that the decrease in the settling pond in treating mining wastewater based on chemical-physical parameters can reduce the pollutant load by 2% (0.0031 kg/second) for the settling pond location 1.21% (0.4281kg/second) for location 2 and 1% (0.0074 kg/second) for location 3.The actual pollutant load of wastewater, physical and chemical parameters are smaller than the pollutant load maximum (CPA<BPM). Actual pollutant load (BPA) of settling pond location 1 is 0.107 kg/second, location 2 is 0.032 kg/second and location 3 is 0.105 kg/second. Meanwhile, the maximum pollutant load (BPM) of settling pond for location 1 is 0.165 kg/second, location 2 is 2.01 kg/second and location 3 is 0.628 kg/second. Decreasing pollutant load in settling ponds. Several factors include vegetation, distance between the source of pollutants (catchment area) and the settling pond, dimensions of the settling pond (retention pond), the process of coagulant application, topography, type of lithology. Keywords : Settling pond, pollution reduction, pollutant load, chemical-physical

Abstract

An Analysis of Lead Metal Ion Levels (Pb2+) has been conducted on water, Cat fish (Pangasius pangsius), Gold fish (Cyprinus carpio L) and Parrot fish (Oreochromis sp.) in abandoned coal mine lake in Tenggarong Seberang sub-district. This research was intended to determine the Pb metal ion levels inside water and fish also to understand its appropriateness to be consumed by humans. This research was done with using destruction method on the woven basket water sample and fish’s meat sample (Catfish, Goldfish, and Parrotfish) and then proceed the analyzed using Atomic Absorption Spectrophotometer (AAS). Pb levels acquired in this research are 0,039 in Parrot fish woven basket, 0,031 ppm in Goldfish woven basket that exceeds the quality standards threshold according to PP RI No. 82 Tahun 2001, dissimiliar with Pb levels in Catfish woven basket in the amount of 0,016 ppm which is still far below the threshold. While the Pb levels in all three fishes are under standard quality threshold according to SNI 7387:2009 about maximum limit of heavy metal contamination inside foods, where the levels in Parrot fish is 0,138 ppm, goldfish meat as 0,060 ppm and catfish meat as 0,041 ppm. Keywords: Parrot fish, Goldfish, Catfish, Pb levels, Threshold
