Abstract

ABSTRACT Research on the growth patterns and eating habits of bearded fish (Esomus metallicus) in the Ogan River was carried out in April-May 2024. This research aims to study the growth patterns of bearded fish and analyze the types of food of bearded fish that live in the Ogan River, Palembang City. The research uses a survey method. Sampling was carried out at 3 stations. Station I is around water vegetation or is a natural habitat for fish, station II is around residential areas and station III is around a rubber factory. The fish obtained were taken as samples from 5 individuals each from each station. Each fish was measured for total length and weight. The sample was then dissected, the stomach was taken. The contents of the stomach are examined to see the composition of the types of food, and measure the total volume of food eaten and the volume of each type of food to determine the largest type of food (Index of Preponderance). The research results showed that the composition of the jangut fish's food was phytoplankton (44.39%), leaf debris (27.26%), zooplankton (0.26%) and unidentified (28.07%). The growth pattern of beard fish is negative allometric or growth in length is faster than growth in weight. Keywords: Esomus metallicus, Index of Preponderance, allometric

Abstract

Research has been carried out to analyze organic C levels in soil samples using a UV-Vis Spectrophotometer. Carbon in soil functions as a food source for microorganisms, which can accelerate decomposition activities and reactions of organic matter in the soil. The aim of determining organic C levels is to determine the amount of organic carbon contained in soil samples, which plays an important role in assessing soil fertility. The analytical method used is UV-Vis spectrophotometry. The analysis results showed that organic C levels in soil samples ranged from 0.15% to 2.27%. Samples with code D have the highest C-organic content, namely 2.27%, while samples with code A have the lowest C-organic content, namely 0.15%. Most organic C levels were detected in the deficiency (low) category. Low levels of organic C in the soil have an impact on plant growth that is less than optimal. To improve the quality and levels of soil organic C, it is recommended to add compost or urea to reach standards that correspond to good soil quality.

Abstract

    Checking blood levels of C-Reactive Protein (CRP) is one of the tests that can detect inflammation at an early stage. C-Reactive Protein (CRP) is an inflammatory marker that is synthesized in the liver. CRP levels increase due to trauma, bacterial infection and inflammation (inflammation and tissue damage). CRP plays an important role in the recognition of microbial organisms and as an immunomodulator in the body's defense system, CRP also plays a role in the recognition of necrotic tissue. Specimens that can be used for C-Reactive Protein examination are Serum, heparin plasma, and EDTA plasma C-Reactive Protein (CRP) examination consists of several methods, including the Latex method, automatic and others. The research design used posttest only design. This study was conducted in April 2023 at the Laboratory of RSU Bunda Palembang which amounted to 21 samples using venous blood samples Results: the results of CRP examination using the FIA method were 9.53 mg/L and CRP examination using the Sandwich Immunometry method was 9.43 mg/L. The results of the research data were analyzed using spss with the Dependent T test. There is no difference in CRP values between the Sandwich Immunometry method and the FIA method in venous blood samples of patients with indications of infection at Bunda Hospital Palembang in 2023.

Abstract

This study aims to analyze the growth rate of marine bacteria producing protease using variations in the concentration of skim milk media and to observe the relationship between cell growth and enzyme activity. The study was conducted using three concentrations of skim milk media (1%, 2%, and 3%) and observation of growth and enzyme activity for 108 hours. The results showed that 1% skim milk concentration produced the largest proteolytic zone diameter (13.8 mm) with the fastest growth (1 day). Observations of cell growth patterns and enzyme activity showed that the highest enzyme activity (0.5933 U/mL) occurred in the early growth phase and decreased in subsequent phases even though cell growth increased. This indicates that there is no linear relationship between cell growth and enzyme activity in marine bacteria-producing protease, where enzyme production and activity are influenced by various complex factors such as physiological conditions of the cells and nutrient availability.
