Abstract

The rise in plastic usage in Indonesia has resulted in a buildup of plastic waste both on land and in water bodies. Because it does not break down easily due to the lack of microorganisms that can degrade it, plastic remains in the environment and pollutes various living beings. Thus, it is important to conduct studies on microplastic contamination to evaluate the safety of fish, which is a widely eaten source of food. This study aimed to determine the abundance and characteristics of microplastics in Ikan Tongkol (Euthynnus affinis) from the coastal waters of Ampenan Beach. Sampling was conducted using a random sampling method. Tuna samples were collected from fishermen along the Ampenan coast three times, totaling 30 fish. The analysis was conducted through sample preparation, oxidation of organic matter, filtration, and microscopic observation. The results showed that microplastics had accumulated in the digestive tract of the Euthynnus affinis, with an abundance of 2.3 MP/Ind. The most dominant type of microplastic found was fiber, accounting for 65% of the total sample, with black being the predominant color. Four types of microplastics were identified in the digestive tract: 65% fiber, 20% fragments, 10% film, and 5% granules.

Abstract

Ekosistem mangrove di Desa Ketapang Raya memiliki nilai ekologis yang tinggi dan berpotensi sebagai sumber belajar IPA, terutama bagi guru dan siswa di sekolah sekitar seperti SMP Gerupuk, Kecamatan Pujud, Lombok Tengah. Terdapat 10 spesies mangrove beserta biota asosiasi (Mollusca, Crustacea, Echinodermata, ikan) yang melimpah. Namun, guru IPA belum memanfaatkan potensi tersebut dalam pembelajaran berbasis lingkungan untuk meningkatkan literasi sains. Kegiatan pengabdian ini bertujuan untuk meningkatkan pemanfaatan nilai ekosistem mangrove sebagai sumber belajar IPA serta menanamkan nilai konservasi lingkungan melalui pendidikan formal. Metode yang digunakan adalah pelatihan, diskusi, dan praktik lapangan. Hasil kegiatan menunjukkan partisipasi aktif siswa dan guru dalam diskusi serta apresiasi terhadap materi pembelajaran berbasis mangrove. Luaran kegiatan berupa publikasi pada jurnal ber-ISSN dan terindeks SINTA.
