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

Abstract

The distribution and abundance of fish are strongly influenced by several oceanographic parameters, one of which is chlorophyll-a. Chlorophyll-a is one of the oceanographic parameters that play an important role in primary productivity in the sea. The distribution of chlorophyll-a contained in phytoplankton can be used as a measure of fertility in water. With advances in geographic information systems or remote sensing, the distribution of chlorophyll-a can be used to estimate fish catchment areas. This study aims to look at the distribution of chlorophyll-a in Aceh waters both spatially and temporally to predict fishing locations. This study used satellite imagery combined with a Geographic Information System (GIS) to detect chlorophyll-a’s distribution. The results of satellite image processing show that the average monthly value of chlorophyll-a in Aceh waters ranges from 2.71 – 23.54 mg/m3, areas with high chlorophyll-a are generally located in the western waters of Aceh to the southwestern waters of Aceh, while areas with The lowest chlorophyll-a is generally in areas far from the coast (towards the open sea) with a range of 0.04 – 0.5 mg/m3 where the lowest average occurs in the east monsoon. However, in general, the potential locations for fishing grounds are more in the waters west of Aceh than in the waters north of Aceh, Aceh waters.Keywords:Chlorophyll-aSatellite imageFishing areaGeographic information SystemAceh Waters

Abstract

Most of the coastal areas of Aceh Besar are areas of accumulation of organic compounds, one of which is Organic Carbon (OC). The purpose of this study was to analyze the chemical content by looking vertically at the content of OC, soil pH and Calcium Carbonate (CaCO3) on the coast of Aceh Besar District. Analysis of the OC content using the Walkley and Black method, while to analyze the Calcium Carbonate (CaCO3) using the Titrimetric method. Especially for the analysis of soil pH, only use a pH meter. The results showed that each station had different levels of OC and carbonate. Generally, the presence of OC decreases with depth, while the carbonate content varies. Especially for soil pH, the pH is relative to the alkaline state for each depth. The range of OC content for all stations is 0.18 – 2.48%, Carbonate 5.36 – 13.27% and pH 6.37-8.73.Keywords:CoastalOrganic CarbonCarbonateSoil pH

Abstract

Sabang waters is one of the centers of capture fisheries production at the tip of the Sumatera Island which has a large potential of fish resources. However, information related to the performance of capture fisheries including fish production, fishing gear, fishing fleet, number of fishermen and fishing areas is still limited. This study aims to analyse and describe information related to capture fisheries performances in the waters of Sabang. Performance data were analysed descriptive quantitatively and obtained by survey method. The results showed that the trend of capture fisheries production tends to increase by 15% annually and catches are dominated by large pelagic fish, namely tuna (Thunnus sp). The type of fishery business is dominated by fishermen who operate vessels measuring 0 - 5 GT (57.9%) with fishing areas between the coast to 2 nautical miles. Fishermen in Sabang Waters are categorized as small businesses. because use small boats and using handlines as fishing gear that aim to meet daily needs, not for business scale.Keywords:Fish productionFishing gearFishing fleetFishing groundCapture fisheries

Abstract

The availability of accurate land data is useful in planning, policymaking, regional development, and preserving the environment. Banda Aceh is the center of education and development in Aceh, Indonesia, which is located in the coastal area. The tsunami has had a significant impact on development and settlements in Banda Aceh. Currently, settlements in Banda Aceh rapidly grow also the need for land and water resources. Therefore, mapping the potential for residential land in Banda Aceh is required. This study examines land suitability in Banda Aceh based on the FAO salinity criteria and spatial data analysis by remote sensing methods. Based on the results, it is known that Banda Aceh has land suitable for settlement of around 85% or 2975 hectares. These areas are generally located close to watersheds and receive sufficient freshwater input. Meanwhile, areas far from rivers and close to the coast have brackish salinity. This area is not suitable as a residential area. There are about three sub-districts in Banda Aceh which are not suitable for settlement.Keywords:KrigingRemote sensingSettlementSalinity mappingCoastalBanda Aceh

Abstract

This research studied the characteristic of bed sediment in the estuary of Krueng Cut, Banda Aceh. Analyzing the field samples from different site of stations along the channel from upstream to estuary shows different pattern and profile of deposited bed sediment. Therefore, sorting the size of sediment is important spatially because pattern of its deposition and characteristic will illustrate how distribution patterns indicate the nature of the channel. Hence, the study aims to determain the pattern of bed sediment distribution as well as its profile spatially. To implement the intended purpose, the coring method was employed by using purposive random sampling for 15 stations of taken sampling. The sample of sediment was proceeded by using a 2,5 cm diameter of PVC paralon at the depth of 25 cm from the bathymetry base. Sample was analyzed using wet sieve analysis method. The result informed that the dominant of bed sediment size are medium sand found around the mouth of the river, fine sand existed along the mixing area, and very fine sand occurred in the transition zone. Inthe region of coastal dynamic, the sediment was dominated by medium sand size, meanwhile in the area of river dominated flow, the sediment is subject to fine sand size.Thus, the fraction of very fine sand size of sediment was found in the zona of transition.
