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.

Abstract. Suparno, Yusra, Lubis AS, Viza AFY. 2024. Influencing the environmental factors on the abundance of puerulus Panulirus homarus in the Mentawai Islands, West Sumatra, Indonesia. Biodiversitas 25: 3758-3767. The lobster puerulus, the final larval stage of the spiny lobster, is significantly influenced by environmental factors, making it crucial for sustainable aquaculture development. This study aimed to analyze how these factors affect the abundance of puerulus Panulirus homarus (Linnaeus, 1758) in the Mentawai Islands, West Sumatra, Indonesia has practical implications for aquaculture. A one-way analysis of variance revealed that the temporal period significantly impacts the abundance of puerulus P. homarus (P<0.05). In February (west season), the abundance was not significantly different from April (transition season I), but both differed significantly from June (east season). The highest abundance occurred in June (33.8±4.21 ind/trip), followed by April (27.00±5.00 ind/trip) and February (23.20±2.22 ind/trip). Regression analysis showed that temperature (R²=0.8111), salinity (R²=0.5158), and phosphate (R²=0.5492) strongly correlated with puerulus abundance. In contrast, chlorophyll-a (R²=0.2236), nitrate (R²=0.4136), and sea current velocity (R²=0.0223) were less significant. These results emphasize the importance of temperature, salinity, and phosphate as key factors influencing puerulus distribution, providing valuable insights for sustainable aquaculture. Environmental parameters were observed using Aqua Modis satellite imagery. They included Sea Surface Temperature (SST), chlorophyll-a concentration, and current velocity, showing a good correlation with field measurements from the Copernicus Marine Environment Monitoring Service (CMEMs).

Abstract

This Community Partnership Empowerment Program (PKM) was launched with the Landia Saiyo Sahati Farmer Group in Kanagarian Koto Tinggi to resolve the issue of post-harvest organic waste, which typically causes environmental pollution and hinders land reutilization. The program established an integrated business system centered on Black Soldier Fly (BSF) larvae (maggot) and catfish. This model utilizes agricultural waste as maggot feed, subsequently employing the high-protein maggot harvest as catfish feed, aiming to substantially reduce production costs and foster new productive economic opportunities. Implementation involved site surveys, socialization, technical training on maggot and catfish cultivation, technology transfer, and continuous mentoring, monitoring, and evaluation. The results confirmed the farmer group’s ability to execute a complete maggot production cycle; the majority of the maggot was utilized for catfish feed, with 15% reserved for breeding stock. Cultivated catfish are now being marketed through local traditional channels. Partner feedback was highly positive, with 91.2% of participants reporting significant enhancement of their knowledge and skills. Ultimately, the PKM contributes to the green economy by effectively managing organic waste and generating sustainable income through this integrated system.
