Abstract

Vibrio harveyi is a Gram-negative marine bacterium from the genus Vibrio known for its ability to emit light (bioluminescence). This bacterium is rod-shaped, moves using flagella at one end, has facultative anaerobic properties, and thrives in environments with high salt content (halophilic). Vibrio harveyi is often found in tropical and subtropical marine waters, especially in coastal ecosystems. Nanotechnology, which is the focus of this study, is a technology based on objects (structures) that are at the nanometer level, often used in biomedical and environmental applications. The purpose of this study was to determine the effect of SLS (nanoenzyme) in inhibiting the growth of Vibrio harveyi, which can cause disease in various marine organisms, including fish and shrimp. The method used in this study was experimental with a quantitative approach, where various concentrations of SLS were tested on bacterial growth. This study was conducted from June to July 2024, under controlled laboratory conditions. The results of this study indicate that the effect of SLS (nano enzyme) cannot inhibit the growth of Vibrio harveyi bacteria at various concentrations, namely 100%, 40%, 20%, and 10%. This is thought to be due to the particle size of the nano, where a smaller nanoparticle size can increase its effectiveness as an antimicrobial. In addition, several other methods need to be tested on SLS (nano enzyme) to understand further its ability to inhibit the growth of Vibrio harveyi bacteria, such as combining with other antimicrobial materials or modifying the nanoparticle structure.

Abstract

This study aims to examine the effect of fermented maggot feeding on the survival and growth of tilapia (Oreochromis niloticus) as an effort to increase feed efficiency in fish farming. Maggots are known as an alternative feed source rich in protein, but the fermentation process is needed to increase the digestibility and availability of nutrients. This study was conducted for six weeks at the Moncongloe Aquaculture Institute using an experimental trial method with a Completely Randomized Design (CRD) consisting of four treatments, namely A (maggots without fermentation as a control), B (maggots fermented with SLS), C (maggots fermented with EM4), and D (maggots fermented with Yakult), with each treatment being repeated three times. The main parameters measured included survival and absolute weight growth of tilapia. Based on the results of the study, the highest survival data was obtained in treatment B with a value of 86.7%, followed by treatments C and D which were each 83.3%, and treatment A (control) of 73.3%. Meanwhile, the absolute weight growth parameter showed the highest value in treatment B at 5.92 g, followed by treatment C at 5.79 g, treatment D at 5.58 g, and treatment A at 5.29 g. The results of the analysis of variance (ANOVA) revealed that the provision of fermented maggot feed did not have a significant effect on the survival of tilapia, but had a significant effect on its absolute weight growth. The treatment of maggot fermented with SLS (treatment B) showed superior results compared to other treatments, indicating that certain types of fermentation can increase the effectiveness of feed in supporting the growth of tilapia. Thus, this study provides scientific evidence that maggot fermentation, especially using SLS, is a potential method to improve the quality of fish feed, so that it can be applied as an innovation in the development of more efficient and sustainable fish farming
