Abstract

Most of the coastal zones of Aceh Besar are areas of accumulation of organic compounds such as C-Organic and CaCO3. Therefore, studying the distribution of organic carbon and carbonates in sediments in coastal areas is necessary. This study aims to analyze the distribution of C-Organic and Calcium Carbonate (CaCO3) coupled with pH and Salinity tests spatially on the surface at a depth of 40 - 60 cm in the coastal area of Aceh Besar District. The C-Organic content was analyzed using the Walkley and Black method, while Calcium Carbonate (CaCO3) was analyzed using the Titrimetric method. Soil pH and salinity tests were carried out in situ using a pH meter, and soil salinity tests were tested using a salinometer. The study results show that the distribution of C-Organic and Carbonate content differs in each location in Aceh Besar Coastal area. The distribution of organic carbon and carbonates in the northern part of Aceh Besar, in the Ujong Batee Puteh area, has an average value of 0.86% and 10.28%. While the distribution of C-Organic in the Lamreh area is, on average, 0.44% and carbonate (CaCO3) is 8.03%. On the other hand, in the western part of Aceh Besar, the distribution C-Organic in the Ujong Pancu area is, on average, 2.83%, and carbonate (CaCO3) is 8.05%. The distribution of C-Organic in the Lhok Seudu area has an average value of 1.07% and carbonate (CaCO3) of 9.65%. The results also reveal the fact that there are 3 (three) factors that influence the distribution of C-Organic and CaCO3. These factors are the topographic location that allows the material to be eroded due to runoff, vegetation that enriches organic matter composition, and the depositional environment. The results of the pH distribution test in soil showed that the pH in the coastal area of Aceh Besar is relatively alkaline, and the salinity distribution is relatively low, indicating the absence of seawater intrusion and salt deposits. Further studies need to be carried out for other depth variations to obtain more comprehensive results of other distributions.

Abstract

The Atomic Absorption Spectrophotometer method (AAS) and UV-Vis Spectrophotometer method are often used in analyzing elements and compounds in water and sediment. The comparative method of AAS and UV-Vis analysis in sediments in this article is studied to see the accuracy of the equipment used and the efficiency of the resulting analysis. Analysis of the comparative method of phosphate analysis in coastal sediments shows differences and similarities in the use of the two instruments used even though the methods used based on the results of the review do not show significant differences. Methodologically, various types of methods can be carried out to analyze coastal sediment phosphates. The UV-Vis spectrophotometric method is generally more widely used than the AAS method. For a small number of sediment samples, the ASS method is more efficient than the UV-Vis method; however, UV-Vis is more accurate for dissolved samples because less phosphate is released when identified than the AAS method. Based on this, the AAS method is more effective in analyzing phosphate sediments in coastal areas than the UV-Vis method, but the UV-Vis method for wet samples is more accurate.Keywords:Coastal SedimentPhosphateSpectrophotometerUV-VisAAS

Abstract

Heavy metal pollution is one of the problems that often occurs in Indonesian coastal waters. Comparative methods of looking at heavy metal content in coastal sediments include a way to show similarities and differences between one or more articles by using certain criteria. Different comparison methods to see the heavy metal content in sediments include the AAS (Atomic Absorption Spectrophotometer) method, AAN (Netron Activation Analysis), Regression, and USEPA methods. Based on the comparison of 2 methods, namely: AAS and AAN methods, the most efficient in analyzing heavy metals in sediments in coastal areas is the Atomic Absorption Spectrophotometry (AAS) method compared to the Neutron Activation Analysis (AAS) method.Keywords:CoastalSedimentHeavy MetalSpectrophotometer
