Abstract

Study on the antioxidant activity test has been conducted using palado (agave angustifolia) leaves from Tondo, Central Sulawesi. Palado plant is one of the succulent plants that can grow to a large size, and it is possible to contain antioxidant compounds. This study was conducted by an experimental method using maceration extraction technique and 1,1-difenil-2-picrylhydrazyl (DPPH) as the free radicals source, and vitamin C as the positive control, whereas UV-Vis spectrophotometer as for determining wavelength (λ) of palado leaves extracts. Sample used as much as 5 grams palado leaves, and methanol as the solvent. Variation concentrations of palado leaves extract were 20, 40, 60, 80, 100, 120, and 140 ppm. The results showed that the IC50 value of palado leaves extract was 26.182 ppm. Palado leaves extract is classified as a very powerful antioxidant based on the IC50 value. The optimum percentage antioxidant activity of palado leaves extract in inhibiting free radicals was by 84.84%.

Abstract

Bioactive compounds contained in red fruit (pandanus conoideus De Vriese) among others are flavonoids and tannins. The compounds are classified as very powerful antioxidants and can inhibit free radicals. This study aimed to determine the effective concentration of the red fruit extract from Poso as an alternative for lowering blood sugar levels. The separatin method used was boiling. The animals test were 15 male of mice (Mmus musculus) induced by ethylene diamine tetra acetic (EDTA). The mice were divided randomly into 5 groups with different treatments. The first, the second, and the third treatments were given red fruit extract each with a concentration of 10%, 20% and 30%. The fourth treatment was given glibenclamide suspension as a positive control, and the fifth treatments was given Na-CMC as a negative control. Data were analyzed using a statistical analysis of variance (Anova) test followed by Duncan test. The results showed that the preclinical test of red fruit extract reduced blood sugar levels of mice, and the most effective concentration was 20% as much as 68% (w/v) with significance level a = 0.05.

Abstract

Moringa (moringa oleifera Lam) leaves contains many molecules as inhibitors for free radicals such as phenolic compounds (phenolic acids, flavonoids, quinones, coumarins, lignans, stilbenes, tannins), nitrogen compounds (alkaloids, amines, betalain), vitamins, terpenoids (including carotenoids), and several other endogenous metabolites as antioxidants. This study aimed to determine the antioxidant potency of water and ethanol extracts of moringa (moringa oleifera Lam) leave obtained by maceration and dekok. The concentration of free radical 1,1-diphenyl-2-picrylhydrazyl (DPPH) was analyzed using UV-Vis spectrophotometer after addition of various concentrations of Moringa leaves extracts. Various concentrations of moringa leave extracts used were 20 ppm, 40 ppm, 60 ppm and 80 ppm. Vitamin C solutions as the positive control were prepared on similar various concentrations. The negative control was prepared using DPPH solutions dissolved in absolute ethanol. The results indicated that the ethanol extract of moringa leaves prepared by maceration method showed the antioxidant potency with an IC50 value of 22.1818 ppm, but the IC50 value of water extract of moringa leaves prepared by dekok was 57.5439 ppm. While, the IC50 value of Vitamin C was 8.8084 ppm. Based on the IC50 data it can be concluded that Vitamin C is a stronger antioxidant than moringa leaves extracts.

Abstract

The Lake Lindu is one of the potential water resources in Central Sulawesi with various species of fish and one of the most commonly found fish are species mujair fish. Mujair fish processing wastes such as offal can be polluted the environment if not managed properly. The study aim is to determine the contents of NPK nutrients in the liquid organic fertilizer by adding MOL banana weevil. The contents of nitrogen (N), phosphorus (P), and potassium (K) was determined by using spectro direct. The NPK contents in the liquid organic fertilizer of mujair fish waste from Lake Lindu reached the maximum NPK contents of nitrogen (N) of 0.311% by addition 100 mL MOL banana weevil, phosphorus (P) 0.167% by addition 150 mL of MOL banana weevil, and potassium (K) of 0.037% by addition 150 mL MOL banana weevil.

Abstract

Today, the battery is the most practical and in expensive energy storage device in a modern community. A variety of new materials technologies has been developed in the manufacture of the battery, especially the development of the solid electrolyte (solid). Polymer Electrolytes can be found in the polymer batteries form such as lithium ion polymer battery. A natural polymer such as chitosan is potential as polymer electrolyte membrane for battery applications. The chitosan has amino and hydroxyl groups that allow for modification. The modification of chitosan membrane is expected to produce the better membranes characters. The aim of this research is to study the effect of the addition of inorganic filler kaolin on the conductivity of the polymer electrolyte that made of chitosan-polyvinyl alcohol than was added to the lithium salt. The ionic conductivity of the polymer electrolyte chitosan-polyvinyl alcohol-lithium-kaolin was measured by using an impedance spectroscopy. The measurement results showed that the polymer electrolyte chitosan-polyvinyl alcohol-lithium with the addition of 4% kaolin provide the highest ionic conductivity is large 6.551x10-5 S/cm. In comparison, characteristics of batteries that made from polymer electrolyte chitosan-polyvinyl alcohol-lithium with the addition of kaolin have a voltage of 2.4 volts which have similarities to the commercial batteries. This result indicates that the kaolin can be used as a filler to increase the ionic conductivity of the polymer electrolyte chitosan-polyvinyl alcohol-lithium, and then it can be developed as a battery.

Abstract

Testing of antioxidant activity of binahong (anredera cordifolia (tenore) steenis) leafs extracts has been done with 1,1-diphenyl-2-picrylhydrazyl (DPPH) using UV-Vis spectrophotometer. The aim of this research was to determine the antioxidant activity of binahong leafs extracts. Concentration of 1,1-diphenyl-2-picrylhydrazyl (DPPH ) after addition of binahong leafs extracts was determined using UV-Vis Spectrophotometer. Various concentrations of binahong leafs extracts were 20 ppm, 40 ppm, 60 ppm and 80 ppm. Vitamin C was the positive control used at similar variation concentrations, whereas DPPH solution dissolved in absolute ethanol was as the negative control. The results showed that the IC50 values obtained for binahong leafs extracts and vitamin C were 40.27 ppm and 49.20 ppm. Based on the IC50 data, it can be seen that binahong leafs extracts are stronger antioxidant than vitamin C.
