Analisis Keanekaragaman Jenis Ikan Menggunakan Environmental Dna (Edna) Metabarkoding Di Perairan Desa Air Putih Kabupaten Bengkalis Provinsi Riau
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 type of sediment in the southern waters of Bengkalis Island are the mud type.
