Abstract

The problems that are often experienced when cultivating goldfish are diseases caused by pathogens that attack cultivated fish. The cause of disease in fish is caused by interactions between fish, pathogens and their habitat environment that can cause death in fish. The solution to this problem is to provide a phytoimmunostimulant derived from mango leaves (Mangifera indica). The purpose of this study was to determine the effect of mango leaves on the hematology and physiology of common carp. This research was conducted in January-April 2022. The method used in this research is an experimental method by comparing data. Parameters observed were total erythrocytes, hemoglobin, hematocrit, blood glucose, absolute body weight growth, survival rate, and water quality. Based on the research that has been done, it can be concluded that the addition of 1.5% mango leaf powder into fish feed as a phytoimmunostimulant affects the hematological and physiological effects of common carp. Common carp treated with phytoimmunostimulants in fresh water had higher mean values ​​(total erythrocytes 1.75x106 cells/mm3, hematocrit 33.66%, and hemoglobin 8.13 g/dL) compared to data in brackish water (total erythrocytes 1.54x106 cells/mm3, hematocrit 30.66%, and hemoglobin 7.76 g/dL).

Abstract

The most commonly used method of vektor control is temephos (the synthetic larvicide). Currently in some areas there has been resistance of aedes aegypti larvae to temephos, so that natural larvicide is required as an alternative. Nypa exctract contains flavonoid compounds that are respiratory toxins that can kill aedes aegypty larvae.This research was conducted in January - February 2019. The purpose of this study was to determine the inhibitory power of nipah extract against larvae in brackhish water. The results of this study are expected to increase knowledge and provide information about the pontential of nipah as a soursce of bioactive compounds. The method used is the experimental method, where the location of the research sampel was obtained at one sampling location point in the Sungai Kayu Ara village, Siak Riau province. The results showed that the average mortality of larvae in nipah laeves in the 60th minute was 55, 80, 100 and 100%. While root extracts have larvae deaths as many as 60 minutes, namely 100, 90, 90, and 100%. For the average mortality of larvae at the root of nipah there are 60 minutes, which are 95, 100, 100 and 100%. As wel as positive and negative controls as a comparison. So it can be compared to 3 administration of nipah extract both leaves, roots and midrib so that the three conncentrations used are better than the use of midrib extract compared to leaf and root extract. It can be concluded that the more concentration used the higher the mortality of larvae is the concentration of 12%. For the concentration used the percentage of larvae mortality in the test media is as much as 6%, 9% and 12%. Every death of larvae has reristance to different bodies so that at the 30th minute there is a difference in mortality of larvae wich a given concentration. The larvae species used are aedes aegyti larvae. The highest mortality of dead es was found in midrib extract and also positive controls. So that the death of larvae is very effective against the given solution has the same ability. The mortality of A. aegypti larvae were then analyzed using probit analysis to obtain LC50 (Lethal Concentration 50) and LT50 (Lethal Time 50) values. The results of the probit analysis of leaf, root and midrib extracts are the estimation of LC50 1.493, 2.618, 0.005. while leaf , root and midrib extracts at the LT50 estimate were 2.841, 1.579, 2.227

Abstract

Spirulina is microalgae that spreads widely in nature and can be found in various types of environments, both in brackish, sea and fresh water. Spirulina is photoautotrophic, so it requires light as an energy source for cell growth and synthesis of various important substances involved in it. Lack of light can cause photosynthesis to not take place normally so that it will affect the growth of S. platensis. This study aims to determine the effect of different light colors on the biomass growth of S. platensis. This research was conducted from March to April 2019 at the Marine Microbiology Laboratory and the Marine Chemistry Laboratory, Faculty of Fisheries and Marine, Universitas Riau. The method used in this research was the experimental method. The study design used was a completely randomized design (CRD) with four treatments (red, yellow, blue and control colors) and three replications. The results showed that the light colors had a significant effect on the biomass growth of S. platensis. Yellow light gave the best biomass growth, followed by red and blue light.

Abstract

This research was conducted from April to July 2019 at the Center for Environmental Technology Laboratory (PTL), Geostech 820 Building, Serpong Region Puspitek, South Tangerang. The aim of this research was to determin growth of Chlorella vulgaris on media added with Pb at different concentrations, and to determine the ability to absorb Pb. The experimental method was conducted by using concentrations of Pb at 3 different levels consisting of 1 ppm, 5 ppm, 10 ppm in triplicate and control treatment without the addition of Pb. Each sample was analyzed by ICP-OES (Inductivly Coupled Plasma – Optical Emission Spectrometer). Data was analyzed by using ANOVA followed by LSD test. The growth of C. vulgaris biomass during the cultivation were Pb 1 ppm (10.38 g / l), k (9.10 g / l), Pb 5 ppm (8.36 g/l) and Pb 10 ppm (7.13) g/l). ANOVA test showed that different concentrations of Pb gave a very significant difference (Sig. <0.05) on the growth of C. vulgaris. Reduction in the concentration of Pb metal in culture media were Pb 10 ppm (96.8%), Pb 5 ppm (96.2%), Pb 1 ppm (90%) and there is no Pb found in control. ANOVA test results showed that C. vulgaris had a very significant effect (Sig. <0.05) on the decrease of Pb metal concentration. This shows that C. vulgaris has the capacity as bioremediation of Pb with different concentrations
