Abstract. Edwin T, Primasari B, Purnama RA. 2023. Characterization of microplastic in trawl fish caught in Padang City (Indonesia) coastal area. Biodiversitas 24: 516-522. Marine organisms can ingest microplastics that are distributed in the oceans. It can harm marine organisms because carcinogenic materials easily attach to microplastics. Trawl fish is a commercial fish with a high demand from people in Padang City, West Sumatera, Indonesia. This study aimed to analyze the abundance of microplastics in the gastrointestinal tract of fish. Also, analyze the microplastic characteristics in trawl fish caught on Pasir Jambak Coast and Purus Coast in Padang City. The species studied were Sulphur goatfish (Upeneus sulphureus), Indian mackerel (Rastrelliger kanagurta), and White sardinella (Sardinella albella). Microplastics were identified using microscopy and FTIR spectroscopy. Microplastic abundance in Sulphur goatfish, Indian mackerel, and White sardinella was 3.89±1.36 per fish, 4.22±1.28 particles per fish, and 2.50±0.46 particles per fish, respectively. The size of the most commonly found microplastics ranged from 1-5 mm and was categorized as the Large Microplastic (LMP) type. Fourier Transform Infra-Red (FTIR) spectroscopy analysis showed that the origin of the type of microplastic polymer found was Polyethylene Terephthalate (PET). Statistically, it shows that the difference in the location and time of sampling does not provide a significant difference in the concentration of microplastics in fish and seawater. The results of this study indicated that microplastics were found in the waters and all fish samples on the coast of Padang City studied. Microplastics in the trawl fish can be used to manage plastic waste in the city to prevent a worse impact due to plastic pollution in the future.

Abstract. Komala PS, Soeprobowati TR, Takarina ND, Subehi L, Wojewodka‑Przybyl M, Primasari B, Edwin T, Arlina L, Mardatillah R. 2026. Phytoplankton community response to seasonal eutrophication in Maninjau Lake, West Sumatra, Indonesia. Biodiversitas 27 (2): d270232. https://doi.org/10.13057/biodiv/d270232. The aim of this study is to analyze the seasonal trophic status of Maninjau Lake using the Comprehensive Trophic Status Index (CTSI) and to examine its spatial and temporal relationship with the phytoplankton community structure. The water and phytoplankton samples were collected from 10 sampling points in accordance with SNI 6989-57-2008 and the ecological protocol. Results show that CTSI values ranged from 62.59 to 73.28, indicating eutrophic to hypereutrophic conditions. The trophic sub-indices showed TSI-TP values of 53.24-82.20, TSI-TN values of 50.97-61.49, and TSI-Chl-a values of 52.98-62.07. Based on spatial analysis, the trophic status is relatively homogeneous across all sampling locations, indicating widespread nutrient loading in the lake. On the other hand, higher CTSI values during the rainy season and temporal variation of CTSI are significant. The increase in CTSI was associated with a change in phytoplankton dominance from Bacillariophyceae under eutrophic conditions to Cyanophyceae under hypereutrophic conditions, reflecting tolerance to increased nutrient concentrations. The hypereutrophic status of Maninjau Lake favored opportunistic taxa, as indicated by an increase in the dominance index and decreases in diversity and evenness. Rainfall contributes to shaping phytoplankton community dynamics, affecting the trophic status of the lake. This study highlights that integrating CTSI, phytoplankton ecological indices, and rainfall variability provides a useful framework for assessing air quality degradation and ecosystem stability in tropical lakes.

Abstract

Floating marine debris is one of the major environmental challenges affecting coastal ecosystems and marine activities. Accumulation of floating debris can interfere with fishing operations by increasing the amount of debris captured in fishing nets and reducing fishing efficiency. This study evaluated the density, composition, chemical characteristics, and recycling potential of floating marine debris along Gajah Beach and Pasir Putih Tabing Beach, Padang City, Indonesia. Floating marine debris was collected using fishing trawls under two environmental conditions: normal weather and one day after a rainfall event. Samples were collected from three sampling points representing the study area and analyzed for debris density, material composition, proximate characteristics, and recycling potential. The average debris density increased from 1.18 g/m² under normal weather conditions to 3.13 g/m² after rainfall. Five material categories were identified, namely plastic, wood, rubber, fabric, and coconut husk. Plastic was the dominant material, accounting for 90% of the debris under normal weather conditions and 50% after rainfall, with corresponding densities of 0.90 g/m² and 1.66 g/m², respectively. Proximate analysis showed average values of 25.05% moisture content, 56.33% volatile matter, 8.53% ash content, and 9.09% fixed carbon. The results also indicate that plastic, wood, fabric, and coconut husk have potential for recycling or resource recovery. These findings provide baseline information for marine debris monitoring and support the development of more effective coastal waste management and resource recovery strategies in Padang City.
