Abstract

The increasing demand for electricity has triggered the development of environmentally friendly alternative energy sources. One promising innovative technology is the Microbial Fuel Cell (MFC), which utilizes electroactive microorganisms such as exoelectrogens to generate electricity from organic materials. This research aims to analyze the impact of organic fertilizer soil and the addition of water on bi-electricity production in MFC systems. The experiment was conducted using organic fertilizer soil as a substrate, with parameters such as voltage and power density being measured regularly. The results show that exoelectrogenic microbes can significantly enhance electricity production, with specific treatments (P2 U1) providing the highest stability in electricity generation over 24 hours. The addition of water also positively impacted microbial activity and electron transfer. This study reinforces the potential of organic fertilizer soil-based MFCs as a sustainable and environmentally friendly renewable energy source.

Abstract

Microplastics have emerged as pervasive contaminants in coastal ecosystems and can accumulate in sessile organisms, particularly bivalves, through filtration mechanisms. This study aims to synthesize existing evidence on microplastic concentration, characteristics, polymer types, and identification methods in sessile organisms using a systematic literature review (SLR) approach. Literature selection was conducted following the PRISMA guidelines, with inclusion criteria limited to primary research articles published between 2015 and 2025. The synthesis results indicate that microplastics are consistently detected in sessile organisms, with concentrations varying among species and locations. Fibers represent the dominant microplastic shape, followed by fragments, while particle sizes are generally within smaller microplastic classes that exhibit high bioavailability. The most frequently identified polymer types include polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET), suggesting predominantly anthropogenic sources associated with domestic and fisheries-related activities. Across all reviewed studies, microplastic identification was primarily performed using spectroscopic techniques, particularly Fourier Transform Infrared Spectroscopy (FTIR) and its variants, which enable accurate polymer determination. Overall, this review highlights the potential of sessile organisms as effective bioindicators of microplastic pollution in coastal environments and underscores the need for standardized analytical methods to improve data comparability across studies.
