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.

Abstract

This study aimed to determine the optimal salinity in increasing the growth rate of Chlorella sp in laboratory scale culture. This research was conducted in July 2023 at the Marine Biotechnology Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Riau. The experimental method was applied using a complete randomized design (CRD) with four treatments and three replicates. The treatments were as follows: T0 (control), T1 (25 ppt salinity), T2 (30 ppt salinity), and T3 (35 ppt salinity). The initial density of Chlorella sp was 250x103 cells/mL, and cell abundance observations were carried out for 14 days. The parameters observed were cell abundance, specific growth rate, and water quality (temperature and pH). The results showed that different salinity influenced the growth of Chlorella sp. 35 ppt salinity gave the best results on cell abundance of 266.66x104 cells/mL, with peak population occurring on day 10. Water quality during the study was still in the normal range and can be tolerated for the growth of Chlorella sp, and the temperature ranged from 25-31oC and pH 6.4-8.0

Abstract

Linear alkylbenzene sulfonate (LAS) is the main component of dispersants that function as cleaners of various materials. The increasing use of LAS causes this compound to dominantly pollute coastal waters. Phytoremediation is the most environmentally safe alternative to physical and chemical methods. One of the potential plants as a phytoremediator is Rhizophora mucronata. This research is an experiment as an application of LAS pollutant control by R.mucronata plants in waters. After acclimatization and preliminary tests, the implementation of LAS phytoremediation tests by R. mucronata plants in seawater media was carried out at concentrations of A1: 25 mg/L, A2: 100 mg/L, A3: 175 mg/L, A4: 250 mg/L, and A5: 325 mg/L and control (Control without plants) as a simulation of the presence of pollutants in coastal waters. The method used was a completely randomized design (CRD) with one treatment and 3 replications. The reduction of LAS concentration in the test media and its effect on R.mucronata leaf chlorophyll and dissolved oxygen were analyzed at week 2 to week 4. The analysis results showed that LAS compounds could be reduced to 91.48% at week 2 and 97.40% at week 4. Plant Water quality parameters (dissolved oxygen, temperature and pH) were measured daily. Based on the study results, LAS can be reduced by R.mucronata plants 87-90.4% in week 2 and 95.1-97.4% in week 4. LAS exclusion by plants had a significant impact on the reduction of leaf chlorophyll content until week 4. LAS reduction by R.mucronata in the media can increase dissolved oxygen content as an indication of improved water quality. R.mucronata plants can be used as an alternative to control LAS pollution in waters
