“…Shipping activities in Rupat strait primarily consist of transportation, storage, and oil distribution [5]. Other than shipping activities, industrial, agricultural, and urban activities are also common on the land across Rupat strait due to rapid growing socioeconomic activities promoted via growing number of populations [6]. Shipping, industrial, and urban activities within the coastal areas of Dumai could potentially give negative impacts to Rupat strait waters.…”

“…Hence, sediment quality was used as a contamination indicator [13]. Research on Rupat strait for the last decade has been done on its physical, chemical, biological analysis [14], organic content analysis [4,15], diatomic characteristics [15], bacterial characteristics [6], sediment characteristics and qualities [1,4], and metal content analysis [4]. This research aimed to determine contamination status of Rupat strait [3,2,16].…”

Rupat strait is located in the north of Dumai, Riau, Indonesia. Rupat strait is the center of shipping, industry, farming, and urban activities. The vast activities are expected to give pressures to Rupat strait ecosystem and its water quality. This study aims to identify the status of Rupat strait water contamination via determination of the degree of heavy metal pollution in Rupat strait water. Samples was taken from 10 location across Rupat strait while the remaining 1 location is the reference location. Sampling was conducted according to SNI 6964.8:2015 in both dry and wet seasons in 2022. The respective physical and chemical parameters were also measured during sampling. Based on the measurement, significant distinction of physical and chemical parameters other than water salinity, TSS, and turbidity (p>0.05) were observed in between wet season and dry season. Rupat strait water was moderately polluted in dry season with Pij 4-8 and mildly polluted in wet season with Pj 3-5. For heavy metal contamination, Rupat strait water was mildly polluted for the whole year with PLI 0.3-0.6. This finding is expected to contribute as references for the surrounding community to maximize the socioeconomic productivity in Rupat strait.

“…Organic matter is needed in water because it is a nutrient for the biota in the waters. However, if the amount of organic matter produced exceeds the threshold it will trigger water pollution 2 . This situation can cause the accumulation of organic matter which can interfere with the life of organisms in the waters, one of which is macrozoobenthos.…”

This research was conducted in March 2022 in the Coastal Waters of Dumai City. This study aims to analyze the amount of organic matter and the abundance of macrozoobenthos and the relationship between the amount of organic matter and the abundance of macrozoobenthos. The method used is a survey method consisting of 10 stations with 2 replications at each station. And 1 station is a control station located on the north coast of North Rupat District, Bengkalis Regency. Sediment sampling was carried out in the field and then taken to the Marine Chemistry Laboratory, Riau University for analysis of organic matter and macrozoobenthos analysis. Based on a simple linear regression test, the relationship between the amount of organic matter and the abundance of macrozoobenthos obtained a correlation value (r) = -0. 4637 with the mathematical equation y = -4.884x + 98.896. The test results show a weak and inverse relationship between the amount of organic matter and the abundance of macrozoobenthos. This means that with the increase in the amount of organic matter, the abundance of macrozoobenthos in the coastal waters of Dumai City will decrease. The value of the coefficient of determination (R2) is 0.2146. This figure shows that the effect of organic matter on the abundance of macrozoobenthos is small, namely 21.46%
