Identifikas Jenis Dan Kelimpahan Mikroplastik Pada Sedimen Di Perairan Dumai Provinsi Riau
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 in
land 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 Dunai coastal waters.
