Abstract

The presence of microplastics is dangerous for fish and human health. The small size of microplastics (0.0001-0.5cm) makes it easier for microplastics to enter and accumulate in the bodies of living creatures. This research aims to analyze the shape, color and abundance of microplastics in fish landed at Pasir Jambak Beach, Padang City. The research was carried out in April - September 2023. Microplastic observations were carried out at the LLDIKTI X Laboratory using an Olympus CX21 microscope. The results of the research showed that the three types of fish landed, namely Mackerel fish (Rastrelliger neglectus), Lemuru fish (Sardinella lemuru) and Tongkol fish (Euthynnus affinis), were contaminated by microplastics. The total abundance of microplastics in three fish meats was 130 particles/g. The highest percentage of microplastic abundance was found in fiber microplastics with a percentage of 77% and the dominant color of microplastics was black.

Abstract

Limbah cangkang kerang lokan (Geloina erosa) merupakan salah satu limbah perikanan yang memiliki kandungan kitosan yang memiliki sifat biorenewable, biodegradable, dan biofungsional. Tujuan penelitian ini adalah untuk mengetahui kandungan kitosan dan karakteristiknya dari cangkang kerang lokan (Geloina erosa). Penelitian dilakukan pada tanggal 20 November - 30 Desember 2025. Isolasi dan karakterisasi kitosan dilakukan di Laboratorium terpadu Fakultas Perikanan dan Ilmu Kelautan, Universitas Bung Hatta. Metode penelitian yang digunakan yaitu deskriptif. Hasil penelitian menunjukkan bahwa kitosan memiliki bentuk seperti serbuk dan berwarna putih. Pada hasil rendemen kitosan diperoleh rendemen tertinggi adalah 15,07% dan terendah 4,22%. Kitosan cangkang kerang lokan memiliki kadar air 1,83%, kadar abu 97,75% dan derajat deasetilasi 26%. Hasil analisis uji FTIR diperoleh gugus fungsi OH dan mode vibrasi regangan NH2.
