Abstract

Aeromonas hydrophila is an infectious agent that triggers Motile Aeromonas Septicemia (MAS) in freshwater fish, including catfish, leading to significant economic losses in aquaculture. This study aims to evaluate the antibacterial activity of Mango Bacang (Mangifera foetida L.) leaf infusion against A. hydrophila and its effect on catfish mortality. The research methods included the preparation of the infusion, phytochemical screening, antibacterial activity testing, and assessing the infusion's impact on catfish mortality. Phytochemical screening revealed that Mango Bacang leaf infusion contains alkaloids, flavonoids, phenols, tannins, and saponins, contributing to its antibacterial properties. The well-diffusion technique used to examine antibacterial effects demonstrated that the infusion at concentrations of 5–100% produced significant inhibition zones against A. hydrophila, with strong activity observed at a 5% concentration (14.38 ± 1.67 mm). However, toxicity testing on catfish indicated increased mortality with higher infusion concentrations, reaching 50% at 5% concentration. These findings suggest that Mango Bacang leaf infusion has potential as a natural antibacterial agent to control A. hydrophila, but its use requires precise dosage management to ensure safety for catfish. Further studies are necessary to optimize effective and environmentally friendly concentrations and explore applications on a broader scale.

Abstract

The Winogradsky column was pioneered by Surgei Winogradsky, a Russian microbiologist. Winogradsky created an isolation tool, he showed how microorganisms play a role in maintaining ecosystem balance and deep sustainability. The aim of this research is to identify and study various microorganisms involved in the conversion of inorganic compounds in the natural environment. The research method uses a descriptive method, which observes and describes the behavior of microorganisms in various environmental conditions. The research was carried out in the Jakung Dusun River, Cilowong Village, Taktakan District, Serang City using glass bottles containing a mixture of water, soil and various other organic materials which allows the formation of gradients of nitrogen, oxygen and sulfur. The research results show that microorganisms can adapt to convert inorganic compounds into more complex compounds with redox reactions.

Abstract

The vegetation composition and structure influence the dynamic of coastal ecosystem at Cemara beach, Kualo Bengkulu. Vegetation play a key role in protecting the environment from natural disasters such as tsunamis, coastal erosion, wave, habitat destruction, and water degradation. Therefore, understanding it is crucial for providing data on coastal vegetation and the impacts of disturbances. This study aims to present baseline data on vegetation composition and structure and carbon stocks. This supporting sustainable coastal forest management as a coastal mitigation effort. The method used purposive sampling with quadratic-transec plot to analyzed vegetation, carbon stocks, and environmental factors. The measurement results are as follows: light intensity in shaded areas was 941 cd, in exposed areas 1465 cd, soil pH 6.8, temperature 36.3°C, wind strength 2.3 knots, and air humidity 58 Rh. Sampling was carried out by counting vegetation in the strata of stakes, poles, and trees. while carbon stocks were calculated in poles and trees. The study obtained 12 types of plants in details: the sapling  was dominated by Terminalia catappa (IVI: 61%), the poles were dominated by Pandanus utilis (IVI: 181.96) and the trees were dominated by Casuarina equisetifolia (IVI: 251.89).

Abstract

This study aims to design and make an environmentally friendly fish smoking tool and contribute to the improvement of fish smoking practices and the utilization of coconut shell waste with a focus on determining the optimal temperature and time for smoking catfish using coconut shell waste as fuel and smoking tools using drum smoker type. The research method includes experiments (experiments) to reduce the mass of samples with time variations (4 hours, 5 hours, 6 hours), temperature variations (90 ° C, 100 ° C, 110 ° C) and organoleptic tests (appearance, taste, texture, and odor). From the results of the study, it was obtained that the optimal temperature and time for smoking salai patin fish had been carried out 3 times the experiment of smoking patin fish with temperatures of 90 ° C, 100 ° C, and 110 ° C respectively with variable times of 4, 5, and 6 hours, the ideal temperature was obtained for the process of smoking salai patin fish using this tool at a temperature of 100 ° C within 5 hours this was analyzed in terms of the appearance of color, taste, texture and smell of salai patin fish.

Abstract

Research of Analysis of Weeds in Rice Plantations (Oryza sativa) was conducted in April - June 2025, located in Wanasari Village, Semendawai Timur District, East OKU Regency. The purpose of the study was to analyze weed vegetation in rice plantations (Oryza sativa). This study uses survey methods. Sampling using on the plot which is carried out based on a rectangular plot measuring 2 m x 2 m with a total of 5 plots is placed systematically. The results of the study found 9 species from 7 genera and 7 families. The nine species are Scoparia dulcis, Ophiopogon japonicus, Ludwigia peploides, Ludwugia octovalvis, Ageratum conyzoides, Fimbristilys littoralis, Cyperus kyllingia, Cynodon dactylon, and Sida rhombifolia. The highest weed density calculation was in the Cynodon dactylon species with a value of 7.8 ind/m2 and the lowest in the Scoporia dulcius species with a value of 2.65 ind/m2. The highest important value index (INP) was Cynodon dactylon with an important value index value of 25.73%. While the lowest important value index was the Scoparia dulcis weed type with an important value index of 16.08%. Diversity index is included in the moderate category with a value of  2,13.

Abstract

  The study entitled The Effectiveness of Dragon Fruit Peel Ecoenzyme in Suppressing the Growth of Staphylococcus aureus Bacteria was conducted on May 8-9, 2025, at the Center for Public Health Laboratory of South Sumatra Province. The method used in the antibacterial test was the disc diffusion method. This study aimed to evaluate the effectiveness of ecoenzyme from dragon fruit peel (Hylocereus spp.) in suppressing the growth of Staphylococcus aureus bacteria, the cause of infection in humans. Ecoenzyme was made with the addition of EM4 to accelerate the fermentation process. Antibacterial activity tests were carried out using the disc diffusion method on NA agar media. The test results showed that dragon fruit peel ecoenzyme did not form an inhibition zone against the growth of Staphylococcus aureus at various concentrations tested. This finding indicates that the ecoenzyme does not have significant antibacterial ability against this gram-positive bacteria. This may be due to the low content of active antimicrobial compounds in the ecoenzyme, or because of the natural resistance of Staphylococcus aureus to the compounds contained in the ecoenzyme.
