Abstract

Microplastics are synthetic organic polymers with size range 0.001-5 mm. The existance of microplastics disperse in the environment are harmful to human and natural ecosystems along with possess damage effects on aquatic organisms. The aim of the research was to determine types and abundance of microplastics in Ngrowo River Tulungagung. Sampling of microplastics was conducted at three locations, namely north city, center city and south city. The stages of the research were start from abiotic factors measurement of water continued with sampling, filtering and drying sample, purifying and separation of microplastics particle and observation using stereo microscope. The microplastics types found were fragment, fiber, filament, granule and foam with the highest average of abundance 13,450 particles.(m3)-1 at the center city. The colors of microplastics obtained were dark blue, transparent, chocolate, white, black, grey and red with the highest number was dark blue. Microplastics are known derived from run off road the plastic particle, plastic degradation of domestic waste, industry and others anthropogenic activities.

Abstract

Microplastics are synthetic polymers with a size range of less than 5 mm. Microplastics dispersed in aquatic environments are hazardous to natural ecosystems and humans. This study aims to identify the types, colors, and abundance of microplastics at Sidem Beach, Tulungagung. Samples were collected from seawater and sediment. The research stages began with measuring abiotic factors of seawater, followed by sampling, sample drying, purification and separation of microplastic particles, and observation using a stereo microscope. The types of microplastics found in seawater include fragments, filaments, fibers, and foam, with an average abundance of 0,01-0,29 (0,1 ± 0,32) particles/L, with foam dominating at 76%. In sediment, the types of microplastics found include fragments, filaments, fibers, and granules, with an average abundance of 1,33-24 (10,8 ± 16,5) particles/kg, dominated by fibers at 55%. The colors of microplastics identified include transparent, blue, red, black, gray, and white, with white being the most common in seawater and transparent in sediment. The microplastics found in water and sediment at Sidem Beach are likely the result of the degradation of plastic waste originating from anthropogenic activities around the beach. Additionally, they may also come from culinary tourism activities along the Ngrowo River, as well as domestic waste, industrial, and agricultural carried by river flow to the coastal area.
