Abstract

Located in Teluk Bayur bay the port is of the five biggest and busiest ports in Indonesia. High sea transportation activities and anthropogenic activities may lead to heavy metal pollution. The purpose of this study was to determine the concentration of Pb and Cu metals, in seagrass (Sargassum sp.) and to analyze the feasibility of consuming Sargassum sp. The method used in this study is a survey method, by analyzing heavy metal at Laboratory Pekerjaan Umum of Riau Province. The water quality temperatures 30-31oC, and salinity of 30-31 ppt, appeared curred velocity 0.06-0.08 m/sec, water transparency 100% with a depth of ± 1 m and pH 7. Pb concentrations the highest is 2.9367 μg/g at stations close to the port and the lowest is 2.2506 μg/g at stations close to tourist areas, and the concentration of Cu metal shows the highest 3.3850 μg/g at stations close to community settlements, and the lowest is 2.7772 μg/g near the port area of ​​Teluk Bayur. Based on the PTWI value, Sargassum sp. those originating from the waters of Teluk Bayur, West Sumatra, are still safe for consumption. Based on the Anova Pb and Cu tests in Sargassum sp. do not different (p> 0.05).

Abstract

This research was conducted in February 2021 in the coastal waters of Pandan District, Central Tapanuli Regency, North Sumatra Province. The purpose of this study was to analyze the type and abundance of microplastics in water and sediment and to determine the relationship between the abundance of microplastics in water and in sediment. The method used in this research is survey method which is carried out by observing and taking samples directly in the field and followed by laboratory analysis. Based on the results of the study, the highest abundance of microplastics in water was 706.67 particles/m³, and in sediments was 14,193.33 particles/kg. The abundance of microplastics in water and sediment did not differ significantly between stations. Simple linear regression test showed that the abundance of microplastics in water had a weak relationship with the abundance of microplastics in sediments.
