Abstract

Organic matter has an important role in marine ecology and it can be used as an indicator of water fertility. The content of organic matter in the waters in a certain amount can be useful for aquatic biota, but if it exceeds the acceptable threshold for the environment and organisms, it can cause disturbances. The content of organic matter in the waters will increase due to waste from households, agriculture, industry, and organic waste from land that is carried into the waters. Various community and industrial activities both on land and waters in the South of Bengkalis Island can provide input of organic matter in the waters. The method used in this research is a survey method that is carried out directly in the field to collect data and samples which are then analyzed. This study aims to determine the content of organic matter in water and sediment and analyze their possible relationship. The results showed that the organic matter content of the water ranged from 34.36 – 35.96 mg/L and the organic matter content of the sediment ranged from 4.78 – 13.78%. The content of organic matter in the waters has not exceeded the quality standard threshold. The results of a simple linear regression test showed a positive relationship with an R2 value of 0.712, which means that the relationship between the organic matter content of water and sediment is quite strong (71.2%). The types of sediment in the southern waters of Bengkalis Island are the mud type

Abstract

Plastics in the environment would eventually be degraded into plastic granules which are called microplastics. In recent years, microplastics have been spread widely not only inland but also in aquatic habitats, where averagely 5% of the plastic produced each year will end up in marine waters. The purpose of this study which was conducted in October to November 2020 was to identify the type and abundance of microplastics in the sediment as well as its possible relationship with the sediment organic matter in Dumai waters. Sediment samples were taken from Dumai coastal waters by using purposive sampling method. Identification of the types and abundance of microplastics as well as the analysis of sediment organic content were carried out in the Laboratory of Chemical Oceanography, Department of Marine Sciences, Universitas Riau. Microplastic and sediment particles were separated using 150 ml saturated NaCl solution. The types of microplastics found are fiber, fragment and films, where fiber was found to be the most commonly found (36.43%), followed by fragments (31.97%) and films (31.60%), respectively. No significant correlation found between microplastic abundance and the sediment organic content in Dumai coastal waters
