Abstract

Plastic waste that is not managed properly will damage the environment by polluting the ecosystem. Plastic in waters can turn into micro-sized plastic waste. Plastics whose size is less than 5 mm are called microplastics. The emergence of microplastic pollutants is caused by increasing population activity in Percut Waters. Percut waters are waters located in the coastal area of North Sumatra where there are many anthropogenic activities that cause the emergence of microplastics. Microplastics can have a negative impact on exposed marine biota. Nowadays microplastics are not only found in the environment, but can also accumulate in the bodies of organisms, for example. This research aims to determine the abundance of microplastics in fish found in Percut waters. The research was carried out in October November 2022 in Percut Waters. Fish samples were caught using nets and the samples were separated from their digestive tract and diluted with the addition of NaCl and H2O2 lauric. The average abundance of microplastics in fish samples ranged from 24294 particles. The fish species where the most microplastics were found was mullet fish with 294 particles. The most common types of microplastics found in total are fiber microplastics.Keywords:MicroplasticDigestionCoastalPercut

Abstract

The Asahan River, located in the Tanjungbalai city area, is used for plantation, agriculture, animal husbandry activities, toilet washing facilities, hospitals, hotels, settlements, and industry causing the decrease water quality of Asahan River. The purpose of this study was to analyze the water quality and status of the Asahan River water quality in the Tanjungbalai City Area and develop a pollution control strategy that needs to be implemented to prevent a decrease in the Asahan River water quality in the Tanjungbalai City Area. Purposive sampling technique as used to determine the sampling station. In this study, there were 6 sampling stations based on the activities of the local community with 3 repetitions of sampling. The data analysis techniques from this study are Water Quality Analysis using the Pollution Index (IP) Method and Water Pollution Control Strategy Analysis. The results of water quality analysis based on the pollution index on Asahan river water in Tanjungbalai City show that the average water pollution index is in the moderately polluted category. The maximum of river water pollution index results were at station 2 is 9,086 and the minimum of river water pollution index results were at station 5 is 6,111.Water pollution occurs due to the parameters of phosphate, detergent, oil and grease, and total coliform which have exceeded the quality standard threshold based on Government Regulation of the Republic of Indonesia Number 21 of the year 2022 concerning Management of Water Quality and Control of Class I Water Pollution.Keywords:Asahan RiverWater pollution IndexWater Quality

Abstract

Sediments are temporary and long-term reservoirs for waste including microplastic particles.  Microplastics are large-sized plastics that are under 5mm in size. microplastic particles with a density greater than water can enter the sediment and accumulate. High water utilization activities can be a way for plastic waste from land to enter the waters, one of the rivers that has high utilization is the Siak River in Pekanbaru city. This study aims to analyze the abundance and distribution of microplastics based on 3 (three) stations in the Siak River. The research procedure consists of sampling, microplastic separation, and microplastic analysis. The results showed that the Siak River in Pekanbaru city contained microplastic types of fragments (32%), films (31%), fibers (25%), and granules (12%). The highest abundance of microplastics was at station 1 with an average abundance of 32.67/kg which was dominated by fragment-type microplastics. The Siak River in Pekanbaru city has been contaminated with microplastics which can be intentionally or unintentionally eaten by aquatic biota.
