“…It is a method used in quantitative and qualitative analysis to determine the quantity and type of particles by describing the optical properties of nanoparticles by absorbing part of the spectrum UV-Vis. By observing the color change of the solution from the pale yellow color of the extract with salt at the beginning of the reaction, it turns to brown at the end of the reaction, which indicates the formation of MgO NPs [16] and when scanning the sample with wavelengths ranging from (200-800) nm the appearance of an absorption peak at 270 nm shown in the Figure (1) , which falls within the resonance range that determines the formation of MgO NPs that is confined between (260-280) nm as stated in studies [17][18]. [21] and NH2 to amines respectively that confirm the presence of protein [22].…”

In our study, the green method was adopted using green tea leaf extract in the preparation of nano-magnesium oxide. This method was chosen in the preparation because it reduces toxicity and produces low-cost materials that do not require high energy and are environmentally friendly. The prepared magnesium oxide was diagnosed using UV-Vis, FTIR, XRD and FESEM techniques. After diagnosis, the prepared MgO NPs was used in the adsorption of heavy metal ions, lead and Cadmium, to determine the optimum conditions for the oxide adsorption process and study the experimental data through adsorption isotherms. (Langmuir, Freundlich and Temkin) in order to clarify how the correlation occurs between the adsorbate ions and the surface of the adsorbent material to understand the mechanism of adsorption.

Nothaphoebe coriacea (in Kalimantan, Indonesia, commonly known as gemor) is a native wetland-plants that can grow well in swampy areas. This tree is distributed throughout South and Central Kalimantan, Indonesia. The bark of Nothaphoebe coriacea is used for bioactive compound source for larvacide, mosquito repellent, hio and glue. The objective of this research was to investigate the ultrasound-assisted extraction methods for the extraction of antioxidants compounds of Nothaphoebe coriacea. The barks were subjected to ultrasound‐assisted ethanolic and hexane extraction followed by fractionation (using ethyl acetate, chloroform, and hexane) and the antioxidant activity test was performed. The activity of antioxidant was carried out through a DPPH method. The highest antioxidant activities are shown in ethanol extract with IC50 value of 72.36 μg/mL and chloroform fraction of ethanol extract with IC50 value of 54.18 μg/mL.

Chicken eggshell waste is a potential source of CaO which can be converted into heterogeneous catalysts. The purpose of this study was to utilize CaO heterogeneous catalysts to make biodiesel from waste cooking oil through the process of transesterification. A total of 4 g of catalyst was mixed with 200 g of waste cooking oil and 60 g of methanol, stirred at a speed of 700 rpm for 6 hours at a temperature of 600C ± 40C. The results were analyzed using GC-MS to confirm the formation of various methyl ester compounds. The product was found to have a density of 855 Kg/m3., viscosity of 3.74 mm2/s (cSt), and flash point of 1350C Based on the results, it be concluded that breed chicken eggshells can be converted as catalysts heterogeneous to make biodiesel from waste cooking oil. This information is very useful for further optimization of mass catalysts heterogeneous CaO from breed chicken eggshells including the production of biodiesel.
