Abstract

The aim of carrying out the research is to determine the abundance and diversity of phytoplankton. The method used in this research is a survey method, namely data collection, documentation, and direct observation in the field. Samples were analyzed at the Marine Biology Laboratory of Riau University. The results of the research show that there are six types of phytoplankton found in the waters of Teluk Lecah Village, Rupat District, Bengkalis Regency, namely Synedra sp, Dactylococcopsis sp, Nitzschia sp, Tribonema sp, Cylindrotheca sp, and Rhizosolenia sp. The first highest phytoplankton abundance was at station II, with an abundance of 0.1660, followed by the second highest phytoplankton abundance at station I, namely the residential area, with an abundance of 0.1494 Ind/L, while the lowest phytoplankton abundance was at station III, namely at the harbor with an abundance of 0. ,0996 Ind/L. The species diversity index at stations I and III, H' > 3, means the level of species diversity is high and the water conditions are not polluted. At station II, 1 ≤ H' ≤ 3 means the level of species diversity is moderate, and the water conditions are lightly polluted. It can be concluded that the H' value still meets the criteria. The species diversity index at all stations, E > 0.5, means that the uniformity of organisms is in balance, and there is no competition for certain places or food. It can be concluded that the E value also meets the criteria. Species dominance index at all stations, D < 0.5 means no dominant species exists

Abstract

Aeromonas hydrophila is a gram-negative bacterium that can infect fish and is zoonotic to humans. Efforts to prevent this bacterial infection can be made using herbal plants due to the content of secondary metabolite compounds. This study aims to explore plants that have the potential as antibacterials, especially A. hydrophila bacteria. This research was conducted in February 2024 at the Marine Biotechnology Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Riau. The experimental method used included the stages of preparation of plant leaf samples and antibacterial tests using Kirby-Bauer discs. The plants used were the leaves of senduduk (Melastoma malabathricum), kantong semar (Nepenthes sp), lime (Citrus aurantifolia), belimbing bukit (Acetosella barreligeri), sirsak (Annona muricata), mucuna (Mucuna bracteata), Israel grass (Asystasia gangetica), and miana (Coleus scutellariodes). The results showed that the leaves of kantong semar, senduduk, and belimbing bukit could inhibit bacterial growth in a strong category. In contrast, the leaves of sirsak, mucuna, Israel grass, miana, and lime were classified as moderately inhibiting the growth of A. hydrophila bacteria. In conclusion, these herbal plants can potentially prevent A. hydrophila bacterial infection.
