Abstract

Bileh fish (Rasbora sp.) is a fish that lives in freshwater and can be found in the waters of Ie Sayang West Woyla West Aceh District. Excessive exploration has caused the population of bileh fish in nature to decrease and be limited. The first step that needs to be done in aquatic resource management is to identify the type of bileh fish to adopt its cultivation techniques. Fish identification can be done morphologically or molecularly. Morphological identification refers to morphometric studies. This study aims to identify bileh fish species from Ie Sayang waters based on morphometric characteristics. The bileh fish was obtained from community catches in September-November 2023. Morphological identification was done by visualizing and measuring morphometric characters. Data were analyzed descriptively, and the relationship between morphometric characters was analyzed by linear regression. The morphology of bileh fish has a fusiform body shape, terminal mouth type, forked caudal fin, and linea lateralis visible from the operculum to the caudal part. Total length (TL) ranged from 36.94-65.78 mm and standard length (SL) 29.01-52.49 mm. The length-weight correlation of allometric fish was negative. TL characters were closely correlated with SL, HL, DFD, ED, CPD, and VFL.

Abstract

Scurrula ferruginea (Roxb. ex Jack) Danser is known for its role as an antimicrobial and antioxidant agent due to its content of phenolic compounds, alkaloids, and terpenoids. S. ferruginea has been widely used in traditional medicine for skin infections, diarrhea, hypertension, and digestive tract diseases. This study aims to determine the antimicrobial and antioxidant potential of various treatments of S. ferruginea mistletoe extracts. The experimental method used in this research is the nested pattern experiment. The extract treatments applied include fresh extract, boiled dry extract, boiled fresh extract, brewed dry extract, and brewed fresh extract. Antimicrobial potential was assessed using disc diffusion and dilution methods. Antioxidant activity (IC50) was determined using the DPPH (1,1-Diphenyl-2-Picryl-Hydrazine) method, and Total Phenolic Content (TPC) was also determined. The results indicate that the highest antimicrobial activity against Escherichia coli and Staphylococcus aureus was found in the strong category of fresh extract treatment, whereas there was no significant effect on Candida albicans growth. The fresh extract treatment exhibited the highest antimicrobial activity with a total phenolic content of 20.77321 mgGAE/mL. The Minimum Inhibitory Concentration (MIC) values for the fresh extract against S. aureus and E. coli were 6.25%, and the Minimum Bactericidal Concentration (MBC) values were 12.5% against both bacteria. The antioxidant value of the fresh extract was 101.26 μg/mL, categorized as moderate. Based on the conducted research, it can be concluded that S. ferruginea leaf extract can inhibit the activities of S. aureus and E. coli, while showing no effect on Candida albicans growth.
