Abstract

This study aims to analyse the concentrations of Total Suspended Solids (TSS) and sediment organic matter, as well as their relationship, in the coastal waters of Bokor Village, Kepulauan Meranti Regency. The research was conducted from December 2024 to January 2025 using a survey method at three observation stations selected based on varying levels of human activity. TSS analysis was performed gravimetrically according to the Indonesian National Standard (SNI 6989.3:2019), while sediment organic matter was analysed using the Loss on Ignition (LOI) method. The results showed that TSS concentrations ranged from 10.4 to 17.56 mg/L and were within the good-quality standard for marine waters. The concentration of sediment organic matter ranged from 3.0% to 5.7%, which is categorised as low. A simple linear regression analysis indicated a weak positive correlation between TSS and sediment organic matter. This suggests that suspended solids account for only 10.1% of the variability in sediment organic matter, with the remaining variation influenced by other environmental factors.

Abstract

The research was conducted in December 2025 in the waters of Pangkalan Jambi. The purpose of this research was to analyze the total oil content in sediments, calculate the abundance of benthic diatoms, and explain the relationship between the total oil content in sediment and the abundance of benthic diatoms. The research uses a survey method; three sampling stations with three replications in each station were surveyed. The results showed that the average oil concentration in sediments exceeded the thresholds set by the Department of Water Resources Quality Assurance/Quality Control Program and the Australian and New Zealand Environment and Conservation Council. The results of the calculation of the abundance of benthic diatoms ranged from 2196.14 ind/cm2 to 3362.84 ind/cm2. The highest abundance is around small ports, while the lowest abundance is around the river mouth. Based on simple linear regression, the relationship between sediment oil content and benthic diatom abundance was y = 8281.7 – 1.1367x, with a coefficient of determination (R2)= 0.875 and a correlation coefficient (r) = 0.935. The value of r states a moderate relationship with a constant value b, which is negative, indicating that the higher the oil content, the lower the abundance of benthic diatoms in sediments.
