IKROPLASTIK PADA SALURAN PENCERNAAN IKAN SIDAT (Anguilla Sp.) DI DANAU POSO SULAWESI TENGAH DAN PEMANFAATANNYA SEBAGAI MEDIA PEMBELAJARAN

Thisstudy aimed to analyze the occurrence and abundance of microplastics in the digestive tract of eels (Anguilla
sp.) from Lake Poso and to implement the findings as an educational poster-based learning medium. A quantitative descriptive
method was employed using six eel samples collected from the Pamona area. Microplastic analysis was conducted through
organic matter digestion using 10% KOH solution, filtration with Whatman No. 42 filter paper, and microscopic particle
identification. The results showed that allsamples (100%) were contaminated with microplastics, with a total of 221 particles
and an average abundance of 36.8 particles per individual. The identified microplastic types consisted of fibers (56.56%),
fragments (23.53%), and films (19.91%), while pellets were not detected. The dominance of fibers suggests that the main
sources of contamination were likely domestic and fishing activities around Lake Poso. The research findings were
subsequently developed into an educational poster, which obtained an average feasibility score of 84% and was categorized
as highly feasible. These findings contribute to scientific knowledge on microplastic contamination in freshwater eels and
demonstrate the potential of local research findings to serve as contextual learning resources for improving students’
environmental literacy and awareness.
