Abstract

Yogyakarta is the second-largest producer of plastic waste
in Indonesia. Plastic waste in the waters can be degraded into mi�croplastics that can enter the body of a fish. This study aimed to de�termine the presence of microplastics in the digestive tract of several
species of fish in Pantai Baron, Yogyakarta, Indonesia. This research
was an exploratory research conducted in April-September 2019 at
Pantai Baron, Yogyakarta. Two species of each pelagic and demersal
fish samples were taken by buying fish caught by fishermen. The di�gestive tract of fish was extracted with 10% KOH, filtered, then visual
identification. Microplastic types were estimated by FT-IR spectrome�try. The amount of microplastic of all fishes was done by Kruskal-Wal�lis test while the number of microplastics of the two categories of fish
was compared with the Mann-Whitney test. A correlation analysis was
carried out between the length of the fish, the weight of the diges�tive tract and the number of microplastics found. Microplastic shape,
color, size, and type data were analyzed descriptively. A total of 78 of
the 80 (97.50%) fish from four species studied contained microplas�tics with a total number as many as 3,651 (mean 45.60 ± 44.31 mi�croplastic/individual). About 100% of pelagic fish samples contained
microplastics, while only 95% of demersal fish samples contained
microplastics. Mann-Whitney test results showed the number of mi�croplastic/individual was significantly different between pelagic and
demersal fish (p <0.05). The most dominant shape of microplastic was
fiber (53.14%), film (36.97%) and fragments (9.89%). The type of pol�ymers detected was polyamide. The results showed that pelagic fish
swallowed more microplastics than demersal fish did because of the
microplastic nature that is lightweight and floats. Microplastic char�acteristic data can be used to estimate the main source of microplas�tic pollution in Pantai Baron so it can be managed appropriately.
